Novel halogen-free and environment-friendly fire retardant and finishing method of novel halogen-free and environment-friendly fire retardant for textiles

Abstract

The invention discloses a novel halogen-free and environment-friendly fire retardant and a finishing method of the novel halogen-free and environment-friendly fire retardant for textiles and belongs to the technical field of functionality design of the textiles. The fire retardant comprises components in parts by weight as follows: 3-4 parts of phosphoric acid, 2-3 parts of ethanol, 0.5-1.2 parts of gamma-(2,3-epoxy propoxy) aminopropyl-trimethoxysilane, 0.2-0.7 parts of vinyl phosphate and 0.7-1.5 parts of urea. The finishing method of the novel halogen-free and environment-friendly fire retardant for the textiles comprises technological procedures as follows: preparation of a work solution, twice-dipping twice-rolling, drying, baking, washing and drying. With the adoption of the novel halogen-free and environment-friendly fire retardant, the fire retardant effect of the textiles is remarkably improved through the synergistic effect of different fire-retardant elements, the development direction of the composite halogen-free and environment-friendly fire retardant is developed, meanwhile, the textiles have good water-wash resistance, and the fire retardant and the finishing method have good market popularization value.

Description

technical field [0001] The invention belongs to the technical field of textile functional design, and relates to a halogen-free environment-friendly flame retardant and a fabric finishing method thereof. Background technique [0002] Textiles are prone to fire, and once ignited, the fire is not easy to contain. Therefore, inhibiting or slowing down the burning of fabrics is of great significance to reducing the occurrence of fires and ensuring the safety of life and property. Because the post-finishing method is simple, flexible, low-cost, and applicable to various fiber fabrics, it has become the main method for producing flame-retardant fabrics. [0003] Flame retardant is a substance that can reduce the burning properties of polymer materials. Its main function is to prevent the fabric from burning while maintaining the original properties of the material. [0004] Halogen-containing flame retardants have many varieties and are widely used. They are an important class o...

[0005] However, when it is burned or thermally cracked, it will generate more smoke, corrosive gases and some toxic products (such as polybrominated diphenyl ethers can generate polybrominated dibenzodioxins and polybrominated dibenzofurans, Chlorine flame retardants will generate carbon tetrachloride when they burn) In July 2004, the RoHS environmental protection directive issued by the European Union clearly stipulated that from July 1, 2006 onwards, new electrical and electronic equipment put on the market must not use more Halogenated flame retardants such as brominated diphenyl ethers or polybrominated biphenyls
