Preparation method of environment-friendly chitosan-based flame retardant

Abstract

The invention discloses a preparation method of an environment-friendly chitosan-based flame retardant, and belongs to the technical field of environment-friendly flame retardants. The method comprises the following steps: mixing a pretreated environment-friendly chitosan-based flame retardant with water in a mass ratio of 1:8-1:10, adding mixed organosilane which is 1-2 times the mass of the pretreated environment-friendly chitosan-based flame retardant, sodium hydroxide which is 0.2-0.3 times the mass of the pretreated environment-friendly chitosan-based flame retardant and benzethonium chloride which is 0.1-0.2 times the mass of the pretreated environment-friendly chitosan-based flame retardant, performing stirring for a reaction, and performing filtering and drying to obtain the environment-friendly chitosan-based flame retardant. The environment-friendly chitosan-based flame retardant prepared with the technical scheme has the characteristics of excellent flame retardant performance, and has broad prospects in development of the technology industry of environment-friendly flame retardant materials.

Description

technical field [0001] The invention discloses a preparation method of an environment-friendly chitosan-based flame retardant, belonging to the technical field of environment-friendly flame retardants. Background technique [0002] Polysaccharide natural polymer materials have the advantages of wide source, low price, biodegradability, renewable and random replacement of fossil resources, and reduction of environmental pollution. They have been widely studied and applied for many years. Natural polymers are diverse in nature and rich in types. According to the differences in their chemical structures, natural polymers can be divided into the following categories: nucleic acids, such as ribonucleic acid and deoxyribonucleic acid; polyamides, such as proteins and polyamino acids; polysaccharides Classes, such as cellulose, chitin chitosan, starch and pectin; organic polyoxygen esters, such as polyalkylene fatty acid esters and cutin; polyphenols, lignin and humic acid; polyiso...
