Improved flame-retardant nylon composite

Abstract

An improved flame-retardant nylon composite is prepared from, by weight, 35-55 parts of high-temperature-resistant nylon, 4-7 parts of chlorinated polyethylene, 2-4 parts of nanosilicon dioxide, 1-3 parts of barium sulfate, 2-4 parts of curing agents, 3-8 parts of molybdenum dibutyldithiocarbamate, 12-16 parts of natural fibers, 0.4-1 part of sodium persulfate, 3-4 parts of butyl methacrylate, 4-8 parts of flame retardants, 8-16 parts of fumed silica, 0.4-0.7 part of chloroform, 1-2 parts of silane coupling agents, 1-2 parts of chain extenders, 4-7 parts of isocyanate coupling agents, 8-14 parts of melamine resin and 1-2 parts of antioxidants. The improved flame-retardant nylon composite has the advantages of excellent flame-retardant effect, good mechanical property, high heat resistance and strength, easiness in operation, environmental friendliness and capability of overcoming adverse effect of high filling quantity of the flame retardants on composite performance.

Description

technical field [0001] The present invention relates to an improved flame-retardant nylon composite material. Background technique [0002] The places where polymers and their composite materials are used are also the main places for human production and life. While they bring unprecedented comfort and convenience to people, they also bring potential fire hazards. Every year, fires around the world cause huge losses to human life and property. In 9 years, 179% of the direct and indirect economic losses caused by fires in my country exceeded 100 million yuan, and almost all of these fires involved polymers and their composite materials. of burning. With the improvement of people's awareness of fire safety, materials with flame retardant properties are more and more widely used in the industrial field and daily life. In order to broaden the application range of high-temperature-resistant nylon and further expand the use of nylon, flame-retardant and glass fibers are widely us...

AI Technical Summary

Problems solved by technology

In order to broaden the application range of high-temperature-resistant nylon and further expand the use of nylon, flame-retardant and glass fibers are widely used in nylon. It is hoped to further improve the performance of nylon to meet the needs of use, but there are still many deficiencies in flame-retardant nylon on the market. , the effects of high temperature resistance, mechanics and corrosion resistance are not good, and the production process is complicated and the cost is high, which needs further improvement
