Composite environment-friendly flame retardant for PC (Poly Carbonate) and PC flame retardant plastic

Abstract

The invention discloses a composite environment-friendly flame retardant for PC (Poly Carbonate) and PC flame retardant plastic. The composite environment-friendly flame retardant is composed of the following components in parts by weight: 10-20 parts of Phosphonic acid, P-[(trimethylsilyl)methyl]-, dimethyl ester, 30-50 parts of melamine cyanurate, 10-20 parts of tri-oxidation bi-antimony, and 40-60 parts of dimethyl methylphosphorate. The PC flame retardant plastic is composed of the following components in parts by weight: 100 parts of PC resin and 6-10 parts of composite environment-friendly flame retardants for the PC. The composite environment-friendly flame retardant for the PC does not contain halogen, has a good flame retardant function, and is mainly taken as engineering plastics to be widely applied to transparent materials, parts of electric appliances, medical equipment, machinery housing and the like.

Description

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

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
