Description

A kind of modified plastics composite membrane

Technical field

The utility model relates to furnishing fields, particularly relates to a kind of modified plastics composite membrane.

Background technology

Along with global economy and the fast development of science and technology, the quality of life of people improves constantly, and the use of home decoration material is also more and more extensive.Overlay film is widely used in home decoration material, door-window section bar and outdoor wallboard.Plastic foil, with its cheap cost, is used widely in a lot of field.

At present, in ornament materials, particularly decoration diaphragm used is generally PVC film above metal material, and there is a significant drawback is exactly that the weatherability of these films is too poor, is easy to weather stain.Often there is the defects such as product surface has line, out-of-flatness, rough, distortion, percent defective high by the colored door and window of direct co-extrusion.

Utility model content

The utility model is exactly that overcome the problem existing for existing composite membrane, the utility model provides a kind of modified plastics composite membrane to satisfy the demands in order to solve the problem.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of modified plastics composite membrane, comprise surface layer, intermediate layer and bottom, described modification composite membrane is made up of at least one deck of surface layer, intermediate layer and bottom, described surface layer is overlying on above intermediate layer or bottom, described surface layer is selected from one or both of PVDF, PMMA, described intermediate layer is selected from one or more of PVDF, PMMA, ASA, PVC, ABS, and described bottom is selected from one or more of ASA, PVC, ABS.

Above-mentioned a kind of modified plastics composite membrane, described composite membrane gross thickness is 0.005-0.5mm.

Above-mentioned a kind of modified plastics composite membrane, PVDF and PMMA of described surface layer is that true qualities are transparent.

The beneficial effects of the utility model are: by modification improving composite membrane performance while, reduce production cost, and expanded the purposes of composite membrane.Because PVDF material itself has good weatherability, durability, resistance to chemical attack and good wearability, stain resistance; PMMA has stronger resistance to ag(e)ing, scratch resistance, weatherability, wearability; ASA has the mechanical properties such as good weatherability, chemical resistance, is therefore finally shown the performance of good weatherability, damage resistant, anti-pollution, rub resistance by the composite membrane of this different materials participation modification.

Accompanying drawing explanation

Fig. 1-Fig. 5 is the utility model specific embodiment structural representation;

Wherein: 1-PVDF (Kynoar); 2-PMMA (polymethyl methacrylate); The 3-ASA terpolymer of cinnamic acrylic ester (propylene is fine-); 4-PVC (polyvinyl chloride); 5-ABS (acrylonitrile-butadiene-phenylethylene copolymer)

Detailed description of the invention

Below in conjunction with the utility model embodiment and accompanying drawing; clear, complete description is carried out to the utility model specific embodiment; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on embodiment of the present utility model, those skilled in the art are not making other embodiments obtained under creative work prerequisite, are all the scopes of the utility model protection.
