Material para forração laminado com múltiplas camadas

Patente de Invenção: "MATERIAL PARA FORRAçãO LAMINADO COM MúLTIPLAS CAMADAS". A invenção refere-se a um material de forração com múltiplas camadas e forma de chapa, que pode ser cortado do tamanho desejado. A invenção refere-se especialmente a uma chapa de base usada como um forro da área de carga de veículos comerciais ou veículos de passageiros. O material de forração é fabricado por meio de uma lâmina moldada de TPO (TPO = poliolefina termoplástica) (12) que é colocada sobre uma camada de apoio (16) de maneira fixa. A camada de apoio (16) é composta de partículas de espuma de PP (PP = polipropileno). This invention concerns a multilayer lining material in the form of sheeting which can be cut to size. Such lining materials are used, for example, as floor plates to cover the loading areas of utility vehicles and as floorboards for passenger vehicles. The lining material can be cut to size, so it can also be punched to obtain a shape corresponding to the loading area.A known lining material which is used as a floor plate consists of a wood fiberboard on the bottom side. A laminated material consisting of a TPO compact film (TPO=thermoplastic polyolefins) with a laminated nonwoven bonded to the wood fiberboard. Thus, the lining material consists of three layers.The known lining material has a complicated design because first a nonwoven must be laminated to the TPO compact film and then the wood fiberboard must be glued to the laminated material consisting of the TPO compact film and the nonwoven. This makes production very cost-intensive. In addition, the finished lining material has a high weight due to the wood fiberboard used in it in particular. Furthermore, the sound insulating effect is unsatisfactory, and finally, disposal of an old floor plate that is no longer needed poses problems because it is made of different materials.The object of this invention is to create a lightweight and yet strong lining material which can be manufactured inexpensively. In addition, the lining material should have a good sound insulating effect and it should be easy to recycle.This object is achieved according to the present invention by the features of Patent claim 1.
