Description
Technical field：
The present invention relates to field of heat insulating materials, and in particular to a kind of back edge sealing type vacuum heat-insulating plate.
Background technique：
Vacuum heat-insulating plate (VacuumInsulationPanel) is a kind of Novel heat insulation material that fast development is got up in recent years
Material, compared to heat-insulating materials such as traditional polyurethane foams or glass fibre, VIP is not used in its production and application process
Ozone depleting substances (Ozone Depleting Substances), and thermal coefficient can achieve 3~4mW/m*K,
Thermal resistance be equivalent to conventional insulation material 10 times are even higher, and its thickness is only the 1/7 of conventional insulation material, have environmental protection and
Energy-efficient two-fold advantage, thus be widely used in fields such as refrigerator, buildings, it is current efficient guarantor state-of-the-art in the world
Adiabator.
Traditional vacuum heat-insulating plate, it is general using covering materials outside three banding envelope types, then vacuum-pumping density is honored as a queen more
Remaining film bag (edge sealing) adhesive tape or glue folding are fixed on product surface.The product of this form, because of size caused by flanging
Deviation is larger, and has used a large amount of adhesive tape or glue, causes the increase of cost.
Application number 201230298065.0 has applied for a kind of appearance patent.Vacuum for building is made using three banding modes
Heat-insulating shield has the function of reducing certain heat bridge.But the covering material that this mode makes can only make, such as of a kind of material
Fruit selects the composite membrane containing Metal Substrate, and heat bridge effect is still very big；Moreover, the not mode of bound edge, causes head and the tail both ends to have
A large amount of membrane material aggregations, are unfavorable for the application extension of product.
Summary of the invention：
The present invention is not concordant after flanging for traditional vacuum heat-insulating shield heat bridge corner, and especially in splicing, gap is excessive,
The drawbacks of causing heat insulation effect to reduce devises a kind of new structural vacuum heat-insulating plate.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of back edge sealing type vacuum heat-insulating plate, it is characterised in that：Using back edge sealing type structure, by membrane material edge sealing position
It is located at the upper surface of film bag, " " font is presented in film bag side view.
The edge sealing position can also be located at below film bag or simultaneously in top and bottom edge sealing.
The edge sealing, at least twice.
Membrane material between the twice edge sealing, can choose same kind, also can choose different type, to reach
Various Optimization Plans such as cost, performance, heat bridge effect.
The film bag inner wall smears insulation cold glue.
The insulation cold glue includes ethylene oxide-capped polyethers 20%~21%, polymer polyatomic alcohol 5%~7%, ammonia
Base polyethers 5%~8%, small molecule dihydric alcohol 5%~7%, coloring agent 0.5%~2%, catalyst 0.5%~3%；Gather to benzene
Naphthalate 20%~22%, glycol-modified~polyethylene terephthalate 8%~10%, poly- terephthalic acids
Fourth diester 3%~5%, thermoplastic elastomer 1%~2%, phosphate ester flame retardants 3%~5%, lubricant：0.01%~
0.05%, soluble metallic salt 3%~5%, surplus is water.
The insulation cold glue preparation method is：Glycol-modified-polyethylene terephthalate is passed through 70~75
DEG C dry 6 hours；
Dried glycol-modified-the polyethylene terephthalate mix making with other raw material
Grain；
The material grain made will be blended and pass through high-speed mixer after mixing, dry 4 is small under the conditions of 145 DEG C -150 DEG C
When；
Stop drying, naturally cools to 35-40 DEG C, soluble metallic salt is placed in high-speed mixer, is stirred evenly；
Continue 70~75 DEG C drying 2 hours, dried mixture is passed through into extruder extrusion molding.
Beneficial effects of the present invention：
" " font is presented in sack made of this mode, side view, and internal packing material can be maximized and outer
The contact of portion's sack surrounding, manufactured vacuum heat-insulating plate side is without extra membrane material, thus caused by reducing conventional products because of flanging
Gap problem when dimensional discrepancy and splicing.
The cold glue adhesive strength is high, and good stability of the dimension, Good Heat-resistance, curing rate is fast, and it is quick to be suitable for automation
Production, it is environmentally friendly, and there is lower cost advantage, it will help improving production efficiency and properties of product；
The cold glue is sharply shunk after heated, is tensed edge sealing, is played better edge sealing effect, while heat shrinkable caudacoria bag
With the contact of internal packing material maximizing, structure is more compact, preferably keeps the temperature；
Using soluble metallic salt, to form the pore structure of perforation in the jelly of extrusion, which is conducive to
Shrink space is provided in subsequent contraction process.
