Abstract

The invention discloses modified polyformaldehyde inflaming retarding plastic. The modified polyformaldehyde inflaming retarding plastic comprises, by mass, 50 parts of polyformaldehyde, 4-6 parts of magnesium hydrate, 2-3 parts of aluminum hydroxide, 2-3 parts of zinc borate, 2-3 parts of melamine and 1-2 parts of phenolic resin varnish. In this way, the modified polyformaldehyde inflaming retarding plastic has the advantages of being high in fire resistance, strength, hardness, rigidity, tenacity, impact strength, corrosion resistance, electrical property, self-lubrication and solvent resistance, safe, practical and the like, and has broad market prospects in terms of popularization.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a modified polyoxymethylene flame-retardant plastic. Background technique [0002] Engineering plastics can be used as engineering materials and plastics that replace metal manufacturing machine parts, etc. Engineering plastics have excellent comprehensive performance, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time, and can replace metals as engineering structural materials. , but the performance of the existing engineering plastics can not meet the higher requirements. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a modified polyoxymethylene flame-retardant plastic, which is formed by adding various flame retardants into the polyoxymethylene matrix to form a modified flame-ret...
