Composite environment-friendly flame retardant for polypropylene, and polypropylene flame retardant plastic

Abstract

The invention discloses a composite environment-friendly flame retardant for polypropylene, and polypropylene flame retardant plastic; the composite environment-friendly flame retardant for the polypropylene comprises the following components in parts by weight: 10-20 parts of trimethylsilyl dimethyl methylphosphonate, 30-50 parts of melamine cyanurate, 10-20 parts of magnesium hydroxide and 40-60 parts of aluminium hydroxide; and the polypropylene flame retardant plastic comprises the following components in parts by weight: 100 parts of polypropylene resin and 25-40 parts of composite environment-friendly flame retardant for the polypropylene. The composite environment-friendly flame retardant for the HIPS does not contain halogen and has good flame retardant function; and the prepared polypropylene flame retardant plastic is not influenced in the aspects of thermal deformation temperature, mechanical temperature, electric insulation performance and the like, has long-term fire resistance, and can be used for easily processing parts with different shapes by injection molding technology, thus being used for making an automobile sealing part, various operating handles, a pull handle and the like.

Description

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

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
