Formula of reinforcement and flame retardant polypropylene

Abstract

The invention discloses a formula of reinforcement and flame retardant polypropylene, which comprises polypropylene, a flame retardant, an antistatic agent, a flexibilizer, a heat resistant agent and a wear resistant agent, wherein the flame retardant is magnesium hydroxide, antimony oxide and hexabromocyclododecane; the antistatic agent is sodium alkyl sulfate; the flexibilizer is a copolymer of ethylene and octylene; the wear resistant agent is glass fiber; and the wear resistant agent is graphite. The formula of reinforcement and flame retardant polypropylene enables the prepared reinforcement and flame retardant polypropylene to have efficacies of good flame retardance, high plasticity, electric static resistance, good flexibility, high temperature resistance, wear resistance and the like.

Description

technical field [0001] The invention relates to a plastic formulation, in particular to a formulation of reinforced flame-retardant polypropylene. Background technique [0002] In recent years, with the improvement of polypropylene production process and polymerization process, great progress has been made in the development and application of high-fluidity polypropylene products; reinforced flame-retardant polypropylene has good processability, mechanical properties, and flame-retardant properties And heat resistance and other advantages, has been widely used as housing parts, connectors and insulating spacers in electronic and electrical products. Polypropylene injection molding products are widely used in packaging, transportation, home appliances, automobiles, offices and other fields. [0003] Polypropylene products are divided into homopolymerization type and copolymerization type, and copolymerization type is divided into block copolymerization type and random copoly...

Problems solved by technology

When the high fluidity homopolypropylene is impacted by low temperature, the toughness is poor, the molding shrinkage is large, and the parts are easy to warp and deform, but its fluidity is good, the tensile strength and bending strength are high; the high fluidity copolymer polypropylene improves the low temperature Impact resistance, good flexibility, high flow rate and good physical properties make the design of large thin-walled injection molded products with complex structures feasible; and the processing cycle can be shortened and the processing temperature can be reduced in the production process , injection molding pressure and energy consumption; it has the advantages of good processing energy, easy punching and less product warping and deformation; relatively speaking, the fluidity of copolymerized polypropylene is slightly worse than that of homopolypropylene, and the tensile strength and bending strength are not as high as High fluidity homopolymer polypropylene
