Composite environment-friendly flame retardant for nylon 6 and nylon 6 flame-retardant plastic

Abstract

The invention discloses a composite environment-friendly flame retardant for nylon 6 and a nylon 6 flame-retardant plastic. The composite environment-friendly flame retardant for nylon 6 is prepared from the following components in parts by weight: 10-20 parts of trimethylsilyl dimethyl methyl phosphonate, 30-50 parts of melamine cyanurate, 10-20 parts of antimony trioxide, 10-20 parts of barium metaborate and 40-60 parts of ammonium octamolybdate. The nylon 6 flame-retardant plastic is prepared from the following components in parts by weight: 100 parts of nylon 6 resin and 10-20 parts of composite environment-friendly flame retardant for nylon 6. The composite environment-friendly flame retardant for nylon 6 is free of halogens, and has favorable flame retardancy. The nylon 6 flame-retardant plastic can be used for producing connectors, reels, timers, protecting cover circuit breakers, switch shell seats, automobile radiator fans, doorknobs, fuel tank caps, intake fences, water tankprotecting covers, lamp holders and the like.

Description

technical field [0001] The invention relates to a flame retardant and nylon 6 plastic, in particular to a composite environment-friendly flame retardant for nylon 6 and nylon 6 flame retardant plastic. Background technique [0002] Fire is a symbol of human civilization. Its application in human life has promoted the progress of history, but at the same time, it can swallow a large amount of social wealth in an instant and endanger people's lives. According to statistics, there are more than 5 million fires every year in the world, nearly 100,000 people die in the sea of ​​fire, hundreds of millions of properties are destroyed, and countless people lose their relatives. [0003] In our country, the fire situation is also not optimistic, and some major fire accidents occur frequently. For example, on November 15, 2010, a major fire broke out in a 28-story apartment building in Jing'an District, Shanghai. The official investigation started because unlicensed welders illegall...

Problems solved by technology

[0007] (2) After the flame retardant is added, it cannot affect the mechanical strength of the plastic, especially it cannot reduce the thermal deformation temperature, mechanical temperature and electrical insulation performance of the plastic product;

Mechanisms such as: protective film mechanism, otherwise gas mechanism, cooling mechanism, and termination chain reaction mechanism are given in existing textbooks. These can provide a vague direction for the selection of flame retardants, but they cannot provide real effective information. s help
