Abstract

The present invention relates to a microencapsulation red phosphorus fire retardation antistatic polyethylene pipe composition, and belongs to the technical field of plastic processing. The composition comprises the following raw materials, by weight, 45-60 parts of a polyethylene resin, 30 parts of an electric conduction carbon black master batch, 6-10 parts of microencapsulation red phosphorus, 6-10 parts of a melamine isocyanurate, 1.0-3.0 parts of a coupling agent, 0.1-0.3 part of an antioxidant, and 1.0-3.0 parts of a dispersing agent. With the present invention, the problem of not good fire retardation effect during fire retardation of polyethylene through single microencapsulation red phosphorus is solved; a synergetic fire retardation agent MCA is added so as to reduce the amount of the red phosphorus and improve a fire retardation effect of the composition; the microencapsulation red phosphorus fire retardation antistatic polyethylene pipe composition is an environmental protection type material, and has characteristics of good extrusion processability and good mechanical property; and compared with the bromine-antimony fire retardation system, the composition has characteristics of low raw material cost, low density, good economic benefits, and good market application prospects.

Description

technical field [0001] The invention relates to a microencapsulated red phosphorus flame-retardant antistatic polyethylene pipe material composition, which belongs to the technical field of plastic processing. Background technique [0002] Polyethylene pipes have the advantages of low cost, light weight, convenient installation, and environmental protection. With the promotion of national policies, they are widely used in various fields. Among them, in addition to the physical and mechanical properties of general plastic pipes, polyethylene pipes for mining should also meet the special requirements of coal mines, that is, they must have antistatic properties and self-extinguishing properties, and the combustion products must not be toxic. Polyethylene is an organic polymer material with a very high volume resistivity of 10 16-20 Ω / cm, static electricity will be generated by friction, and it will accumulate on the plastic surface, which may cause fire and gas explosion. Ther...
