Aviation interior decoration thin-film composite material and method for preparing same

Abstract

The invention discloses an aviation interior decoration thin-film composite material and a method for preparing the same. The aviation interior decoration thin-film composite material comprises a material layer, an aluminum foil layer and a grid layer. The material layer is made of compositions of one type or a plurality of types of PVDF (polyvinylidene fluoride), PVF (polyvinyl fluoride) and PEEK(polyether-ether-ketone), the thickness of the material layer is 18-25 micrometers, the grid layer is made of nylon 66 fibers, plain weave or cross weave is carried out on the nylon 66 fibers, the distance between every two adjacent fibers is 2-3.5 mm, and the thickness of the aluminum foil layer is 6.5-12 micrometers; the material layer is arranged on one side of the aluminum foil layer, and thegrid layer is laid on the other side of the aluminum foil layer. The aviation interior decoration thin-film composite material and the method have the advantages that the aviation interior decorationthin-film composite material is light, is low in surface density and good in flame-retardant property as compared with ordinary interior decoration materials, and a layer of PET (polyethylene terephthalate) materials on each layer stricture is omitted; mass production can be implemented by the aid of the method, the method is high in efficiency and yield and low in cost, and the like.

Description

technical field [0001] The invention relates to a film composite material for aviation interior decoration and a preparation method thereof. Background technique [0002] The aerospace field has high requirements for interior materials, which need to have properties such as light weight, flame retardancy, anti-fouling, corrosion resistance, and wear resistance. Conventional vehicle-grade interior film materials have low strength and poor installation and processing performance. The insulation effect is poor, the quality is heavy, and it cannot meet the requirements of use. Problems such as moisture are prone to occur during use, and the maintenance cost is high, so it is not suitable for long-term service. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a film composite material for aviation interior decoration and a preparation method thereof. [0004] The technical solution of the pr...
