Description

LAMINATED BENDED PANEL, PREFERRED PARABOLIC, WITH MIRROR AND PROCEDURE FOR ITS MANUFACTURING

TECHNICAL FIELD OF THE INVENTION Solar mirror, parabolic mirror

TECHNICAL PROBLEM

A technical problem solved by the invention of the patent is the issue of rigidity of thin-walled curved mirrors. Curved mirrors are known in the art, and are commonly used, as can be seen in the description of the prior art. The curvature of thick-walled parabolic mirrors is otherwise performed at high temperatures. Due to the thickness of the glass, such a mirror has poor performance and also does not achieve as high an accuracy as a cold-curved thin mirror. In addition, its attachment is problematic, which eventually breaks. This technical problem is solved with thin-walled mirrors, which themselves (a) do not have sufficient rigidity to bear their own weight and (b) do not retain their shape after bending, but return to their original shape. They are also impossible to attach without supporting layers.

It is particularly important for the implementation of the present invention that a thin-film glass mirror or some other thin-film reflex metal or plastic material could be successfully used as a solar reflex material. To date, there is no serial production of parabolic thin mirrors, despite the fact that such a mirror has a somewhat higher efficiency than the existing thick glass parabolic mirrors. The method and method of manufacture and composition of the laminated panel described herein (for the purposes of this application also referred to as a multilayer mirror) will give the rigidity sufficiently large to allow thin parabolic mirrors to be used and not to be broken.

BACKGROUND OF THE INVENTION

Multilayer mirrors are described in detail in U.S. Patent 7,077,532, which is referenced in this application and is summarized by reference. The patent comprises a glass mirror and a composite panel where the back of the mirror is attached to the front of the composite panel.

Advances in the prior art are disclosed in JP 57,198,403, which describes a sandwich composition of a panel in which a thin-layer mirror is attached to a rigid panel such that the mirror is curved along the surface of the rigid panel by curving a middle layer comprising a honeycomb and secured to a rigid glue panel. This patent application is also referenced in this application and summarized by reference.

There are still more solutions to be found, which are further away from the new solution of this invention than those cited above.

In the prior art, laminated (multilayer) panel is known, which as such is not new, insofar as we would use quality filler material (9) extruded PVC, which has a price of 25 EUR / m2 at a thickness of 15 mm and was chosen in previous studies as the best. This material is expensive and difficult to produce in large quantities. Nevertheless, the rigidity and time stability of such a parabolic mirror does not satisfy all the requirements. There is still a foam filler material that loses its shape under load.

DESCRIPTION OF THE NEW SOLUTION

The technical problem described above is solved by a laminated curved panel, preferably parabolic, with a mirror and a process for its manufacture. According to the invention, the panel presented is lightweight, rigid, robust and accurate.

The essence of the invention is in the implementation of a laminated curved panel to which is attached, either exhibit or non-exhibit, mirror, preferably glass, or other light reflecting layer, such light reflecting layer being well known in the art. For the purposes of this application, the term "light reflecting layer" includes any layer, regardless of composition, which reflects light to such an extent that it is technically usable for the purposes of which mirrors or other light reflecting surfaces of the prior art are used, preferably for the purposes of solar mirrors.

According to the prior art, a thin-walled mirror is attached (glued) to a sheet of comparable tensile properties. In fact, there are no sheets with the same tensile properties as glass. A solid joint of two surfaces that extend differently results in a shear stress in the joint (adhesive). Insofar as the joint is made primely, and insofar as it does not compensate for its tension properties, the joints are transferred to both layers. Because glass does not or does not tolerate shear stresses (as well as tensile and flexural), it breaks down in the event of a different elongation (due to, for example, temperature rise or fall, or temperature difference), which is an undesirable consequence. These stresses also cause the bursting of all the layers that make up the light-reflecting surface, ultimately separating the reflex layer directly applied to the glass.

According to the prior art, the sheet of metal is further attached to the core and to the other layer of sheet.

The solution to the technical problem so defined is in the construction of a panel to which a light reflecting layer is attached (which, as already written, can be either a glass mirror or another light reflecting surface such as metal foil backed, preferably Au, Ag, Cu, Al etc. which are suitably peeled or otherwise surface treated to maximize the reflectance of the sun's rays and furthermore the layers are weatherproofed with as thin transparent coatings as possible).

Also in US 7,077,532, the light reflecting layer is attached to a laminated panel, only to give the top layer of the laminated panel used there a sheet.

In the embodiment of the present invention, a mesh, preferably a metal mesh, may be used instead of a sheet metal, it may also be made of artificial materials that tolerate tensile strengths similar to metallic materials. The mesh is glued to the back of the light reflecting layer, and due to the freedom levels that the mesh has, it allows it to stretch (and contract) along with the mirror. The elongation coefficient of the material is not decisive, because the geometry of the mesh causes it to be overburdened by excessive overload or a difference in the tension of the wire (or knit fibers) forming the mesh. The mesh comprises wires of which it is composed, the term wire for the purposes of this application means any constituent material of the net, including but not limited to metal knitting, plastic knitting, fiber knitting, nets made by perforating or cutting metal and non-metallic materials, and compact nets made by plastic injection molding.

This solution differs from JP 57,198,403 in that it is not a honeycomb structure (which is, by its nature, medium rigid), but rather a structure which, in combination with a thin-layer mirror and adhesive, will serve as a supporting layer and will transmit all forces through spacer material through the bushings to the other supporting side of the panel.

The reticle is glued to the light reflecting layer with an adhesive, preferably with a polyurethane adhesive (it can also be epoxy or TPU / temperature-sensitive polyurethane adhesive / obtained in foil form, heated to 80 ° C and polymerized) or with epoxy adhesive .

The mesh is attached to a spacer material, preferably of expanded polystyrene (styrofoam), which is pre-punched prior to assembly and molding, for example by holes in diameter after embodiment and in raster according to embodiment described below.

The spacer material is intended for the manufacture of bushings made of filler-adhesive material, preferably polyurethane or other suitable material. Binders are essentially cylindrical or prismatic elements that connect the mirror mesh on one side to the supporting sheet or mesh on the other, thus providing adequate rigidity to the panel to which the light reflecting layer is attached. Alternatively, synthetic or natural rubber bushings with suitable admixtures, plastic or other suitable material may be made.

In the embodiment, the bushings are designed to fill the holes in the spacer material with the filling and adhesive mass before assembling the panel so that, after curing, the bushings are fixed to the mesh and the light reflecting layer on one side and to the outer support layer on the other. , or to a mesh attached to the inside of the outer carrier layer, or to the mesh and outer carrier layer.

The laminated curved panel according to the invention may also have several layers which further increase the rigidity and strength, but this does not change the essence of the invention.

The laminated curved panel according to the invention is designed to assemble a multilayer panel by first placing a light reflective layer on the assembly surface (either a thin-layer mirror coated with an adhesive layer or a different light reflecting layer or a sandwich panel comprising light reflective foil, preferably metal, adhesive layer and inner support layer), at least a mesh in the adhesive mass or laid on the adhesive layer is placed on this layer, a hole spacer material is provided thereon, which also has holes filled with adhesive mass, and on this spacer material lay at least an outer protective layer that may have a reticulum attached to the inside. Such a panel, in whole or in part, during the process, is laid on an internal convex molding tool (mold), and on such an assembled structure it is placed on an external concave molding tool and pressed together by a hydraulic or other suitable press, both of which may be molding tools. greta. The panel is thus shaped into the desired shape, preferably parabolic.

As a result of the press, the adhesive fills in the remaining gaps, for example through holes in the hole spacer material, the spaces between the wires of the mesh, and the rest of the adhesive is extruded along the sides. The panel can remain in the mold (between molding tools) until it dries. The excess adhesive must then be removed from the edge, but the edge may be sealed with a border before compression, or an adhesive tape that prevents the adhesive from leaking out and does not need to be cleaned later.

In the embodiment, through holes are inserted into the spacer material. After filling these through holes with a suitable adhesive, preferably polyurethane or epoxy, and after hardening them, the holes are formed, which become the supporting element of the multilayer mirror of the present invention. According to this embodiment, the bushings fasten at least two webs that are connected to the bushings through the spacer material on both sides. The rigidity according to this embodiment no longer depends on the properties of the spacer material, but rather the rigidity depends most on the hardness of the adhesive. In addition to the adhesive, both meshes are important, as they greatly contribute to the rigidity of preferably thin support plates (3 and 14) and (19 and 14), respectively, when a light-reflecting layer uses a thin-layer glass mirror or a thin-layer metal reflective material or any material that it forms a layer that can be designated as a light reflecting layer according to this application.

In the embodiment, the laminated curved panel comprises at least a mesh 7 such that the adhesive of the spacer adhesive layer 8 fills substantially all the blank spaces between the wires of the mesh and further fills substantially all of the holes 10 in the spacer material 9, with the adhesive on the other side of the contact stretcher z and secures the outer support layer 14, and in the specific embodiment also the mesh 12.

The laminated curved panel thus constructed is fixed on the outer (concave) side to the outside by the light of the reflecting layer, which according to the embodiment comprises either:

(a) light reflecting layer 1 of reflex material, preferably flexible, preferably polished metal or non-metallic film, metallized film, adhesive layer 2, inner support layer 3, preferably sheet or thin-layer polyurethane layer, or (b) reflective layer 19, preferably of carrier polyester, teflon, acrylic, polyurethane, glass material with a micron layer of metal with high solar reflectance, such as silver (Ag), Al, Ni, Cr, Ti, Cu and others, and alloys of these or other metals.

Thus, at least two embodiments are performed according to the patent:

The laminated curved panel according to the first embodiment thus comprises a light reflecting layer 1, preferably flexible, preferably a foil, which is attached by an adhesive layer 2 to an inner support layer 3, to which a mesh 7 is attached to the adhesive layer 8 such that the adhesive of the spacer adhesive layer 8 fills the majority of the voids between the wires of the retina and further adheres to the filler-adhesive mass of the filler-adhesive layer 11, which fills substantially all of the holes 10 in the spacer material 9, with the filler-adhesive mass of the filler-adhesive layer 11 further to the second sides of the spacer material 9 contacts and secures the mesh 12 and the outer support layer 14.

The laminated curved panel according to the second embodiment thus comprises a reflective layer (19) to which a mesh 7 is glued to the adhesive layer 8 such that the adhesive of the spacer adhesive layer 8 fills the majority of the empty spaces between the wires of the mesh and further adheres to the filling-adhesive the mass of the adhesive layer 11, which fills substantially all of the holes 10 in the spacer material 9, wherein the filling and adhesive mass of the adhesive layer 11 further contacts and secures the mesh 12 and the outer support layer 14 on the other side of the spacer material 9.

The commercially available reflective materials thus prepared reflect light layer 1 having adequate protection against UV rays and atmospheric influences on the reflective layers. On the market, the materials are available under the designation 3M VM2000 radian mirror film, 3MSA-85 school film, ACROSOLAR, ACRYLIC and others. Some materials have adhesive layer 2 already applied on the back, so it does not need to be applied separately. The overall thickness of the material thus prepared is very thin and in practice ranges between 50 and 200 microns. There are a number of other materials in development, such as SYLVERED POLYMER TECHNOLOGY and / or Advanced Solar Reflective Mirror (ASRM), presented by Science Applications International Corporation (SAIC) and the National Renewable Energy Laboratory. All such materials are very thin and consequently require a robust supporting parabolic shape - for example, the solution of the invention in layers 3-16. In the technology described above, the high-reflective solar layer fabrication is protected by an ALUMINA glass front coating with Ion Beam Assisted Deposition Technology (IBAD). 3M is developing Ali polymeric multilayer RADIANT technology to bring solar radiation reflectance up to 99%. For all development materials with a reflective layer up front, manufacturers are still improving the UV protective layers and only the layer's robustness and durability in all different weather conditions.

In a particular embodiment according to the invention, the light reflecting layer 1 is attached by an adhesive layer 2 to a support sheet or a solid composite material of the inner support layer 3. When different thin films are used for the reflex material of a thin-layer mirror 1, the material of the inner support layer 3 may be preferably 0.5 - 1 mm thick sheet of aluminum or steel or a similar alloy which is properly galvanized or painted. Material 3 may also be a non-metallic composite containing glass, carbon or other fibers. The thickness of the composite material of the inner support layer 3 is also preferably between 0.5 and 1 mm.

Lay the layers so prepared 1,2,3 on a flat surface with the light reflecting layer 1 facing down. Apply a side adhesive layer 4 to the periphery of the inner support layer 3 and then a protective edge 5. The process is easier if the adhesive layer 5 is already prematurely applied.

Apply an intermediate adhesive layer 6 to the prepared composition of Ido 5 layers. Lay a mesh 7 on the intermediate adhesive layer 6. Transfer the prepared layers 1-7 from a flat surface and place them on a convexly shaped inner part of the forming tool 17. spacer material 9 adhesive spacer adhesive layer 8. With the adhesive coated spacer material 9, turn it over and place it on layers 1 to 7 which are already laid on the inner part of the forming tool 17. Now apply filler-adhesive mass of the filler-adhesive layer 11 to the spacer material 9 and fill through holes 10, for example with a spatula. After curing the filler adhesive, preferably polyurethane or epoxy, through holes are formed in the through holes 10. Alternatively, substantially cylindrical or prismatic plugs of suitable material, for example rubber, polymeric material, polyurethane, polyester, polyester or polyester can be inserted into the holes 10 of the spacer material 9. full or tubular pipe material, preferably aluminum.

In this way, the connecting pieces 20 connect the entire assembly to a suitably rigid laminated curved panel via meshes 7 and 12 and the outer 14 and the inner support layer 3 or the reflective layer 19.

Adhesive layers 6, 8, 11 and 13 can be one or two component polyurethane or epoxy adhesives that achieve adequate hardness at room temperature for 10 minutes to one hour. At elevated temperatures, the curing or polymerization time of the adhesive can be only a few minutes. In the specific specific embodiment, the adhesive used by the Slovenian manufacturer MITOL MITOPUR A2 / 45 was used. All other adhesives that are sufficiently high in strength and non-aggressive and adhesive to the layer 3 and 19 material, mesh 7 and 12 and spacer material 9 may also be used. temperatures. These films may in practice be either low temperature (60-80 ° C) thermoplastic polyurethane TPU or high temperature (150 ° C) ethylene vinyl acetate (EVA film) or temperature reaction macromolecular adhesive. In the case of adhesive films, the filler adhesive mass 11 must be used in addition to the film to fill the holes 10 in the spacer material 9, and the adhesive mass in the holes 10 must adhere to the material of the two adhesive layers. 8 and 13. In the case of thermoplastic adhesive films, the outer 18 and 17 of the forming tool must be heated to the appropriate temperature at the time of compression, depending on the type of film used.

The spacer material 9 may be any suitable carrier material, preferably polystyrene, polyurethane, polyvinyl chloride (PVC) foam, cardboard or aluminum honeycomb. It is important for the adhesive layers 6, 8, 11 and 13 to be non-aggressive and gives it a stable temperature range of -40 to + 80 ° C. The load-bearing capacity, elongation and rigidity of the material are of less importance, since its role is merely to keep distance in the manufacture of the object of the invention. It is important that the spacer layer 9 has pre-made holes 10, which are filled in the manufacturing process by the filler-adhesive mass of the filler-adhesive layer 11. The advantage of the process and object of the invention is that soft, cheapest and lightest spacer materials can be used , while their quality does not affect the rigidity, accuracy and lifetime of the product. The rigidity of the product is determined by the adhesive and filler material 6, 8, 11 and 13. In a special embodiment, expanded polystyrene (polystyrene) was used for spacer material 9, into which holes of 6-8 mm in diameter x 50 mm in diameter were made. , which does not limit otherwise meaningful embodiment of the invention and other dimensions of holes and raster.

In a specific embodiment, at least two meshes 7 and 12 are provided at the outer support 14 and the inner support layer 3. In the case of non-metallic materials, glass, carbon or other non-stretchable plastic nets may be used. The thicknesses of the wires (threads) of these meshes are preferably between 0.2 and 0.5 mm and the mesh openings (windows) are preferably from 5 x 5 mm to 10 x 10 mm. In most cases these are knit nets with square openings. In a particular embodiment, a 0.3 mm thick fiberglass mesh with 5x5 mm openings was used. The rigidity of the fabricated panel was lower than that of metal meshes, but significantly greater than if the mesh were not used. If any of the meshes 7 or 12 is of metal, it should be of the same material as the materials of the carrier layers 3 or 13. When using a 1 mm thin glass as a reflex material of thin glass, the mesh shall be of steel having a coefficient of expansion 11 x 10 ' ⁶ m / m K to 13 11 χ 10' ⁶ m / m K (glass has a coefficient of expansion between 5.4 χ 10 ' ⁶ m / m K and 9 χ 10' ⁶ m / m K). Using the mesh, the disadvantages of the solution of US patent 7,077,532 were remedied, where a metal sheet was glued directly to the glass. Different metal meshes 0.5 mm thick were used for the experiment. The openings may be larger than for non-metallic meshes. We tried different types of meshes. There is no significant change in stiffness if different nets of the same thickness are used. Expanded metal mesh is most suitable for its price and weight. Perforated sheet nets that are slightly more expensive and heavier can also be used. As much as a welded mesh is used, which due to the method of making double thickness and therefore greatly contributes to the rigidity, the consumption of adhesive is greater. A knitted metal mesh that has approximately the same characteristics as a welded mesh may also be used.

In a particular embodiment, a spacer material 9 is applied to the filler-adhesive mass of the filler-adhesive layer 11 with all other layers on the lower part of the forming tool 17 and a second mesh is applied on the second flat surface. of the outer support layer 14 glue the outer adhesive layer 13. With the adhesive coated, the outer support layer 14 is turned and placed on the inner forming tool 17.

In order to avoid dimensional variations in the shape of the multilayer mirror at different temperatures, it is advantageous that the outer support 14 and the inner support layer 3 are of the same material.

As soon as all the layers are placed on the inner molding tool 17, with the precision hydraulic press, we approach the outer molding tool 18 and compress all the layers with it,

preferably with a force of 2-6 bar. Experiments have found that vacuum mode compression as described in US 7,077,532 is not sufficient.

The inner 17 and the outer molding tool 18 may have directional ducts in which hot water or oil flows. This way, both parts of the tool are warm and the polymerization time of all the adhesives is shorter.

After a time depending on the type of adhesive and the temperature of the inner 17 and the external molding tool 18, preferably 5 minutes to one hour, when all the adhesive layers 6, 8, 13 and the filling and adhesive mass of the filling and adhesive layer 11 have solidified, the press opens . A laminated curved panel is removed from it. Immediately afterwards, all the outer edges are cleaned so that U profile 16 can be attached to them. To do this, first cut U profiles 16 to the appropriate lengths at an angle of 45 degrees, squeeze the weight of the adhesive layer 15 into them and then place them on all four edges, so that the mass of the adhesive carrier layer 15 fills the space between the curb and all layers of composite material as much as possible. U profiles are always designed to grasp the curved panel in its shape and further strengthen it.

In the practical case, we used U profiles made of ALUMINUM and stainless steel.

In case we do not use a light reflecting layer 1 of thin flexible reflex material, but instead of layers 1 to 3 we use either a thin glass mirror (preferably 0.8 - 1.2 mm,) or a carrier sheet with a light reflecting layer or a supporting composite instead of layers 1 to 3. the material on which the light reflecting layer is already applied, the manufacturing process proceeds exactly the same as in the first case, with the application of the adhesive layer 2 and the thin flexible reflex material light reflecting layer 1 omitted.

When a thin glass mirror was used as the reflecting layer 19, the solar mirror of the manufacturer AGC ASAHI GLAS EUROPE was used. The glass was 0.9 mm thick and 1500 x 1400 mm in size. Instead of glass, we also used Al sheet thickness 0.5 and thickness 0.7 mm as reflective layer 19. The material is MIRO-SUN and is from the manufacturer ALANOD. The reflecting surface is anodized, then coated with a PVD process and a nano protective transparent layer.

In all cases, the product robustness achieved is sufficiently large to prevent deformation under the influence of higher wind speeds. At the INSTITUTE OF METAL STRUCTURES in Ljubljana, the basic characteristics of the composite were also measured. If a 1500 x 1400 mm multi-layered curved mirror is fixed four points and exposed to winds of up to 100 km / h, there is no overload. Likewise, manufactured mirrors were already exposed to the weather for one year without noticeable consequences.
