Abstract

The invention discloses a PVC composite material used for forming a sunlight-shielding fabric fiber skin layer. The PVC composite material comprises PVC matrix resin, a phosphorus-nitrogen flame retardant and an ethylene-vinyl acetate copolymer. In addition, the invention discloses a preparation method and application of the PVC composite material. The method disclosed by the invention utilizes asynergistic principle of the phosphorus-nitrogen flame retardant and the ethylene-vinyl acetate copolymer, and the obtained sunlight-shielding fabric fiber skin layer not only has good flame-retardantperformance, but also has better mechanical properties; in addition, antibacterial properties, UV resistance and color fastness properties of the obtained skin layer can also meet the needs of a market; and a sunlight-shielding fabric prepared from the skin layer is suitable for architectural sunshading and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of polymer materials. Specifically, the present invention relates to a PVC composite material for forming the fiber skin layer of sun fabrics, its preparation method and application. Background technique [0002] In the field of building sunshade, solar fabric is a kind of product that is widely used. As the name suggests, sunshine fabrics are functional auxiliary fabrics used to block sunlight and ultraviolet rays. According to different subdivision functions, some sunshine fabrics focus on flame retardant performance, some focus on antibacterial performance, some focus on anti-ultraviolet performance, some focus on color fastness performance, and some focus on environmental protection performance. As the national laws and regulations on energy conservation and emission reduction become more and more stringent, the market demand for high-flame-retardant solar fabrics is increasing. [0003] Sunshine fabric is a te...
