MULTILAYER LAMINATED MATERIAL WITH INHERENTLY LATENT PROTECTION AGAINST DEFORMATION UNDER THERMAL ACTION FOR COMPENSATING THE BIMETALLIC EFFECT

摘要

A solvent-free multilayer laminated material comprises a lower substrate layer comprising a thermoplastic polymer or a mixture of thermoplastic polymers, an intermediate layer comprising a flexible material, a further fibrous intermediate layer comprising plastic and provided with an adhesive material, and an upper layer of metal, plastic, or wood or wood-like material. An independent claim is included for a process for the production of a multilayer laminated material comprising introducing the material for the lower substrate layer into one half of an injection mold and the material for the upper layer into the other half of the injection mold. After the mold has been closed the flexible material is injected between the lower substrate layer and the upper layer at 150-330[deg] C and 5-2500 bar. The mold temperature is adjusted to be 8-160[deg] C on both sides. The mold is cooled to ambient temperature for 0.01-5 minutes.
