Composite environment-friendly flame retardant for ABS (Acrylonitrile Butadiene Styrene) and ABS flame-retardant plastic

Abstract

The invention discloses a composite environment-friendly flame retardant for ABS (Acrylonitrile Butadiene Styrene) and ABS flame-retardant plastic. The composite environment-friendly flame retardant for the ABS consists of the following components in parts by weight: 10-20 parts of trimethylsilyl methyl methylphosphonate, 30-50 parts of melamine cyanurate, 10-20 parts of zinc borate and 40-60 parts of magnesium hydroxide. The ABS flame-retardant plastic consists of the following components in parts by weight: 100 parts of ABS resin and 20-40 parts of composite environment-friendly flame retardant for the ABS. The composite environment-friendly flame retardant for the ABS contains no halogen, has high flame retardant function and excellent compatibility with the ABS, is not migrated, separated or extracted in the ABS, is easy to disperse uniformly, has high weather resistance and lasting property and is not decomposed in a high-temperature fusion and thermal forming processing project;the performance such as the thermal deformation temperature, the mechanical temperature and the electrical insulation of the prepared ABS flame-retardant plastic are not affected; and the plastic haslong-term flame retardancy.

Description

technical field [0001] The invention relates to a flame retardant and ABS plastic, in particular to a composite environment-friendly flame retardant for ABS and ABS 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 illegally operated, ...

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
