Abstract

The invention relates to a flame-retardant polypropylene barrier explosion-proof material. The material is of a porous reticular structure and can divide a space into a plurality of small units; and the material is prepared from, by weight, 70-80 parts of polypropylene, 20-30 parts of a halogen-free composite flame retardant, 5-10 parts of a compatibilizer, 1-3 parts of a synergist and 1-2 parts of an antistatic agent. The barrier explosion-proof material can be customized into matched specifications according to the shape of a gas pipeline, and is of the porous structure, and the space of thestructure is divided into the plurality of small units. The barrier explosion-proof material provided by the invention belongs to a nonmetallic material, has flame retardant property, has the advantages of oxidation resistance, low possibility of deformation, high strength and low cost compared with a reticular aluminum alloy material, is filled in a gas transmission pipeline, has less influenceon the liquidity of gas, and has good barrier explosion-proof effect.

Description

technical field [0001] The invention relates to the field of fuel oil and gas barrier explosion-proof technology, in particular to the application of a porous flame-retardant polypropylene barrier explosion-proof material filled in a gas pipeline. Background technique [0002] In recent years, hazardous chemical explosion accidents have occurred frequently at home and abroad, and the safety production situation is severe. Typical dangerous chemicals, such as natural gas, gasoline, ethanol, combustible metal dust, etc., have huge safety hazards due to their flammable and explosive characteristics, especially accidents caused by combustible gases have occurred frequently in recent years, and their use and storage Transportation safety has always been the focus of attention. Therefore, for the storage and transportation of flammable gases, liquids, and high-risk dust, research on new high-efficiency fireproof and explosion-proof materials has become an important means of preve...
