Abstract

The invention discloses a method for preparing sunshine fabric fiber with high flame resistance and high mechanical strength. The sunshine fabric fiber comprises a core layer and a skin layer, whereinthe core layer is prepared from polyester fiber; the skin layer is prepared from a PVC (Polyvinyl Chloride) composite material; a weight ratio of the PVC composite material to the polyester fiber is(60 to 80):(40 to 20). The method comprises two steps of PVC composite material pelleting and polyester fiber coating, wherein the step of the PVC composite material pelleting comprises the steps: stirring PVC matrix resin, a phosphorus-nitrogen flame retardant, an ethylene-vinyl acetate copolymer and an optional additive according to a certain proportion, thus obtaining a PVC composite material mixture in uniform dispersion; extruding the PVC composite material mixture by using a double-screw extruder, and pelleting after cooling by a water tank, thus obtaining master batches of the PVC composite material. According to the preparation method disclosed by the invention, a synergistic interaction principle of the phosphorus-nitrogen flame retardant and the ethylene-vinyl acetate copolymer is utilized, and the obtained sunshine fabric fiber not only has good flame resistance, but also has better mechanical performance; in addition, the antibacterial performance, the anti-UV (Ultraviolet)performance and the color fastness performance can also meet demands of a market, sunshine fabric can be prepared and is suitable for building shading, and an application prospect is wide.

Description

technical field [0001] The invention belongs to the field of textile fiber materials. Specifically, the present invention relates to a high flame retardancy and high mechanical strength solar fabric fiber for building sunshade and its preparation method. 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 ...
