Abstract

The invention discloses a transparent cold-resistant flame-retardant polypropylene material and a preparation method thereof. The material comprises the following components in parts by weight: 65-85 parts of polypropylene resin, 0.1-0.3 part of white oil, 5-20 parts of ethylene-octene copolymer, 3-10 parts of linear low-density polyethylene, 1-5 parts of phosphorus-nitrogen-bromine composite flame retardant, 0.1-0.4 part of flame-retardant synergist, 0.1-0.4 part of nucleating agent, 0.2-0.5 part of antioxidant and 0.2-0.5 part of lubricant. The phosphorus-nitrogen-bromine composite flame retardant comprises the following components in parts by weight: 60-90 parts of organic or inorganic hypophosphite, 10-30 parts of phosphoric-acid-containing piperazidine hydrobromide and 0.5-5 parts of silane coupling agent. The polypropylene material disclosed by the invention has high transparency and high cold resistance as well as flame retardancy. The material has the advantages of favorable compatibility and precipitation resistance, and can be used for preparing plastic products requiring high transparency, high cold resistance and flame retardancy.

Description

technical field [0001] The invention relates to a transparent cold-resistant and flame-retardant polypropylene material with high transparency, low temperature resistance and flame retardancy of the material; the invention also relates to a preparation method of the flame-retardant polypropylene material. Background technique [0002] Polypropylene (PP) is a general-purpose thermoplastic obtained by the polymerization of propylene. Due to its rich source of raw materials and relatively simple synthesis process, PP has the characteristics of low density, low price and good processability compared with other general-purpose thermoplastics. Its yield strength, tensile strength, surface hardness and elastic modulus are all excellent. And it has outstanding environmental stress cracking and wear resistance, and has been widely used in various fields of industrial production. [0003] Due to the relatively slow crystallization speed of polypropylene melt, large spherulites are ea...
