Abstract

The invention belongs to the field of textiles, and particularly relates to a preparation method of a textile flame retardant. Acrylamide and maleic anhydride are used as basic raw materials and mixed with an additive and the like to form a raw material A, then glycidyl methacrylate and the like are used as basic raw materials to form a raw material B, and next, the raw material A and the raw material B react under the action of an initiator and the like to form a porous structure. Maleic anhydride modified acrylamide coated acrylate polymers improve the flame retardant effect, then copper sulfate is utilized to form nano-copper under the action of sodium hypophosphite, the nano-copper is deposited on the polymers, and meanwhile, aminosilane is added to improve the water resistance and improve the bonding performance with the fabric; and polyglutamic acid and the polymer are compounded, the degradation performance of the flame retardant is reduced through aminosilane, and the geraniol can be well wrapped and combined by utilizing the polyglutamic acid to form the textile flame retardant, so that the problem of poor flame retardant effect of an existing flame retardant is effectively solved.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a preparation method of a textile flame retardant. Background technique [0002] Cotton fiber has excellent moisture absorption and air permeability, good dyeability and ecological relevance, and is widely sourced and economical, so it is widely welcomed by people. But cotton fiber belongs to flammable fiber, has the danger of burning, and the fire caused by cotton fabric has seriously affected people's life and property safety. While cellulose fibers bring us various products, they also bring us fire hazards. For example, a large number of textiles and interior decorations used on airplanes, trains, and ships, including carpets, curtains, and wallpapers, are very flammable substances. In response to this situation, many countries have successively formulated many flame retardant regulations. In order to prevent fire and protect the safety of human life and property. As an...
