Self-adhesive laminate and method of making it

Abstract

A decorative laminate includes a laminate substrate coated with an adhesive layer. The adhesive layer is a layer of a physically setting, solvent-free adhesive material including an acrylic polymer. The adhesive layer is self-adhesive at room temperature. The adhesive-coated laminate substrate has a peeling-off force of at least 0.2 N / mm2, after application on a carrier. A method for the production of the adhesive-coated laminate substrate, its use as a coating material, and a composite of the adhesive-coated laminate substrate and a carrier material are also provided.

AI Technical Summary

Benefits of technology

[0014] Another object of this invention is to provide a decorative adhesive-coated laminate substrate, which adheres rapidly and firmly on a carrier substrate surface, without having to accept the long waiting times.

[0025] The previously mentioned advantages provide a relatively simple and easy to install adhesive-coated laminate substrate for the private user and the craftsman without mechanical equipment. The processing can be undertaken directly on site, without machines or special apparatuses having to be used for the processing. By the simple and rapid possibility of the application, the adhesive-coated laminate substrate in accordance with the invention is suitable, in particular, also, for the home user, to upgrade and cover furniture, door surfaces, walls, etc.

Problems solved by technology

With a nonuniform adhesive application and an inexact maintenance of the pressing pressure, pressing temperature, and / or pressing time, unsatisfactory results can be obtained during the cementing.

Thus, for example, excessively high temperatures can lead to warping and material damage.

Low temperatures or pressures often result, on the other hand, in an insufficient adhesion.

Furthermore, the use of solvent-containing adhesives is generally classified as problematic from a health and environmental policy viewpoint.

The use of dispersion adhesives on a water basis, such as casein glue, frequently leads to the partial swelling of the carrier surface, which is frequently the case, for example, when using particleboard as the carrier material.

Furthermore, the drying of water- or solvent-containing adhesives may require several hours.

The circumstances mentioned above often make the use and the successful processing of laminated sheets relatively difficult, particularly for the private sector or in the craftsman's sector.
