Abstract

The invention relates to a composite flame retardant for polyesters and an application method thereof. The flame retardant is prepared through compounding any one of melamine cyanurate (MCA), melamine polyphosphate (MPP) and aluminium diethyl hypophosphite (1240) with bis(1-oxyphospha-2,6,7-trioxa bicyclo[2.2.2]octyl-4-methyl) phenyl thiophosphate (PPS-PEPA) in any weight preparation. The flame retardant disclosed by the invention has the advantages of multielement synergy, good material compatibility, high flame retardancy, environmental friendliness, and capability of reducing the application costs and the like.

Description

technical field [0001] The invention relates to a composite flame retardant for polyester and an application method thereof, in particular to a composite flame retardant for polyester PET and PBT and an application method thereof. Background technique [0002] The wide application of organic polymer materials has brought great convenience to people's lives, but because of its flammability, it often brings fire threats to human beings. Therefore, all countries in the world are committed to promoting the research of flame-retardant technology and flame-retardant materials. At the same time, the research on new, efficient and environment-friendly flame retardants is more urgent. [0003] The widely used polyesters are mainly PET for chemical fibers and PBT for engineering plastics. my country's engineering plastics PBT consumption is about 2 million tons / year, of which about 1 million tons / year is used for flame-retardant modification, and flame-retardant modified PBT is mainl...
