DE1594021B - Process for attaching cladding made of wood, cardboard, metal or plastic to any surface - Google Patents

Description

Approval of the installation of a tub and sound-absorbing cladding on walls and ceilings in that special slatted frames or slatted frames are omitted as fastening elements. Also are previous plastering work no longer necessary. In 5 of the previous use of special adhesive and Reaction adhesives, which did not foam, had to be absolutely necessary to attach the plates a level surface must be provided in order to achieve the largest possible gluing; here but the necessary level surface was often difficult to produce, such bonds were only flawlessly on a small part of the surfaces to be bonded. The one scored with the foam glue Filling all cavities between the unplastered wall or ceiling and the cladding or insulation panel then results in a 100% connection of the entire slab and sub-floor surfaces. This achieves that the plate one has an absolutely solid bond with the subsurface and no condensation can form later.

By filling all the joints, including the one between the ceiling and the wall, with foam and through the additional heat and sound insulating effect of the bond and by filling the wall and uneven ceilings also experience the sound and heat insulation compared to the previous one Procedure attached insulation boards a significant improvement.

The foam bonding also creates an absolutely moisture-insulating layer between the masonry and insulation boards.

A major advantage of the method according to the invention is that the cladding work Can already be done after the shell is already finished with windows and doors was provided, so that the interior has become winterproof. As a result, it is possible To complete buildings regardless of weather conditions in any season. There a drying out the rooms are omitted due to the omission of the plaster in the method according to the invention, are those according to Rooms lined with this method are ready for occupancy much earlier.

Embodiment

The insulation boards 2 (30 x 30 cm) cut to the appropriate wall height or ceiling area 1 are with 50 g of a mixture of 1 part polyether (molecular weight 3000 to 3500) and 1 part diisocyanate provided, which foams after application. The applied foam should definitely have a result in an even layer between 3 and 10 mm, depending on the unevenness of the substrate 4. After the foam has been applied, the insulation board 2 is pressed lightly onto the wall or ceiling 1. The foam is soft and easily deformable. Due to the favorable ratio of the Plate surface to its weight, the adhesive effect is so great that the plate is now shifted sideways can be. There is no further need to fix the plate. After a corresponding Time (about 30 minutes) the foam solidifies. Their final hardness or final strength reaches the Foam adhesion after 1 to 2 hours.

An application of a coating on rough and Claim: uneven surfaces are therefore difficult to achieve bound and the bonding less than satisfactory. Method for attaching cladding The object of the invention is to provide a method for attaching made of wood, cardboard, metal or plastic to bring cladding made of wood, cardboard, metal To create a substrate made of the same or one and plastic, in which on simple other material by means of an intermediate layer way a relatively thick cellular adhesive layer Structure, characterized by a structure that is marked directly at the place of use, that it can be placed on one of the surfaces to be connected that have a firm bond a layer of a hardening, not yet OK on smooth as well as on very rough and uncured Manufactures plastic foam that ensures flat surfaces and where the cellular Cladding presses onto the substrate and the structure of the adhesive layer even after it has hardened allows the foam to harden in situ. remains and thus at the same time an insulating layer forms. 15 The subject matter of the invention is a method for Attaching cladding made of wood, cardboard, metal or plastic to a substrate from the same or a different material by means of a It is already known, panels or insulating interlayer of cellular structure. The method is plates on their subsurface with the help of adhesive 20 characterized in that one of the fabrics to be attached. In addition to the connecting surfaces, a layer of hardening, conventional gluing is also known, as is the so-called foam plastic foam that has not yet hardened, in which the adhesive solution creates foam and substances are added to the cladding by pressing it onto the substrate. In most cases, the foam is allowed to harden in situ,
worked with foam impact devices. After the end of the foaming and after the foam formed, the cell structure of the artificial lining is applied to the hardening with glue applicators, which then practically does not apply to the sub-fabric foam at all. This hafgrund is pressed on, whereby the foam structure is firmly destroyed without being destroyed. Such a working method is surrounding surfaces and connects them with one another, tedious and expensive, and the aqueous glue by using all the solutions available to him is not suitable for a wide range of applications and therefore all unevenness in the area of application. facing surfaces of the to be connected to one another Fills in parts for attaching ribbons, badges, signs. The application of the foam adhesive can be advantageous known, a prefabricated pressure-sensitive adhesive layer on the 35 with appropriately equipped two-component carrier produce, which applied as a fine-pored foam spraying and foaming devices per se will. In this case, a rubber-like known type will be carried out.
