Abstract

The invention discloses a flame-retardant material for textiles and a preparation method, and relates to the technical field of flame retardants. The flame-retardant material for the textiles comprises, by weight, 85-90 parts of ammonium polyphosphate and 5-10 parts of a siloxane coating agent, wherein the siloxane coating agent comprises, by weight, 5-8 parts of siloxane resin, 5-8 parts of a solvent and 0.1-0.3 part of a curing agent. By means of the material, an ammonium polyphosphate flame-retardant product and a textile material have good phase solubility so that the flame retardants canfully exert the flame-retardant effect. The material can be used for flame retarding of decorative fabrics, and the flame-retardant performance can reach the level B1; the material can be used for flame retarding of protective clothing fabrics, and the flame-retardant performance can reach the level B.

Description

technical field [0001] The invention relates to the technical field of flame retardants, which are used for flame retardant of textile products, and more specifically relate to a flame retardant material used for textiles and a preparation method. Background technique [0002] Textiles are a product made of textile fibers through processing and weaving. They are divided into two categories: woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. The main producing areas are Puyuan in Zhejiang and Qinghe in Hebei. [0003] With the development of modern science and technology and the progress of the textile industry, the types of textiles continue to increase, and their application scope continues to expand and extend to all aspects of people's production and life. However, textile materials are generally flammable or combustible, which can easily cause fire accidents. According to statistics, more than 20% of the fire acci...
