Abstract

The invention discloses a high performance self-cleaning building structure membrane material and a preparation method thereof. The preparation method comprises the technical steps as follows: (1) the preparation of a sizing agent for a PVC coat, (2) the PVC coat, and (3) superficial treatment. Compared with the prior art, the invention has the advantages as follows: polyvinylidene fluoride (PVDF) solution modified from acrylic ester is used as a surface treatment agent containing fluorine; wherein, the acrylic ester ensures the interconsistency between a surface treatment layer and the PVC coat, and ensures the handling characteristic of the product; and the polyvinylidene fluoride ensures the antifouling property, self cleaning and resistance to elements of the building structure membrane material; through adjusting the compoment ratio of the acrylic ester and the polyvinylidene fluoride, the comprehensive effect that the performances such as the working quality, the self cleaning, the resistance to elements, etc. of the building structure membrane material are combined is obtained.

Description

technical field [0001] The invention belongs to the technical field of architectural membrane materials, and more specifically relates to a high-performance self-cleaning building that can be widely used as roof materials for large stadiums, open stands, arched inflatable warehouses, open-air exhibition halls, hangars and other buildings. Structural membrane material and its preparation method. Background technique [0002] Architectural structural membrane material (hereinafter referred to as architectural membrane material) is a branch of polyester fiber reinforced polyvinyl chloride composite material. It is the most outstanding quality and strongest variety in this series of products. , The international standard for fire protection. The application of architectural membrane materials in China is developing rapidly. According to statistics, in 1995, the use of architectural membrane materials in my country was less than 10,000 square meters, but b...
