Problems solved by technology

[0002] Nowadays, due to the increase in population density and the concentration of housing, textiles have become a major consumer in housing interior decoration, but textiles are known to be flammable materials, and fires caused by textiles are rarely reported, which will lead to Great loss of people's personal safety and economic property
At present, most of the existing flame retardant finishing agents on the market are halogen flame retardant finishing agents. Hydrogen halide gas and carbon monoxide, carbon dioxide, nitrogen oxides and other gases produced by the combustion of the fabric itself will cause secondary damage to the human body, affect human health, and even cause cancer

Abstract

The invention discloses a novel environment-friendly flame-retardant finishing agent. The novel environment-friendly flame-retardant finishing agent is prepared from, by weight, 20-30 parts of glycerophosphate, 10-25 parts of ethylene glycol monostearate, 5-11 parts of ammonium acetate, 8-12 parts of hydroxymethyl cellulose, 3-7 parts of chitosan, 4-9 parts of potassium xylenesulphonate, 11-22 parts of guaifenesin, 6-12 parts of ethoxymethylenmalonic acid diethylester, 2-7 parts of 3-(2-aminoethylamino)propyl-dimethoxymethylsilane and 15-25 parts of sorbitol. The flame-retardant level and flame-retardant property of the finishing agent can be significantly improved, and the finishing agent is environmentally friendly, free of pollution and friendly to the environment.

Description

technical field [0001] The invention belongs to the field of finishing agents, and in particular relates to an environment-friendly flame-retardant finishing agent and a preparation method thereof. Background technique [0002] Nowadays, due to the increase in population density and the concentration of housing, textiles have become a major consumer in housing interior decoration, but textiles are known to be flammable materials, and fires caused by textiles are rarely reported, which will lead to Great loss of people's personal safety and economic property. At present, most of the existing flame retardant finishing agents on the market are halogen flame retardant finishing agents. Hydrogen halide gas and carbon monoxide, carbon dioxide, nitrogen oxides and other gases produced by the combustion of the fabric itself will cause secondary damage to the human body, affect human health, and even cause cancer. Therefore, there is an urgent need to develop an environmentally fri...
