Problems solved by technology

However, in recent years, brominated flame retardants have been troubled by the problem of dioxins. At the same time, the polymer materials flame-retardant with its bromine-antimony system will generate a large amount of smoke and corrosive gases during thermal cracking and combustion, and the antistatic property is not good. Strong, the European Union and Japan have issued laws and regulations to prohibit the use of such flame retardants

Abstract

The invention relates to a halogen-free flame-proof antistatic polypropylene agglomerate comprising raw materials of the following constituents (by weight proportion): polypropylene 20-40%, combustion inhibitor 30-60%, aliphatic acid 1-4%, aliphatic acid metallic soap 1-2%, charcoal forming agent 1-5%, antistatic agent 10-20%, anti-oxidant 0.1-1%.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant and antistatic polypropylene master batch, which has high-efficiency flame-retardant performance and antistatic performance, can be used for electronic and electrical components and polymer products with environmental protection requirements, and belongs to the technical field of modified polypropylene. Background technique [0002] Polypropylene is a general-purpose plastic widely used in various electronic and electrical components. However, nearly 80% of the flame retardants used in the current flame-retardant polypropylene are halogen-containing flame retardants, especially the bromine-containing flame retardants represented by polybrominated diphenyl ethers and polybrominated biphenyls have high efficiency and low dosage. The performance of the material has little influence, and the price is moderate, and its performance and price ratio cannot be matched by other flame retardants. Therefore, 7...
