Abstract

The invention discloses a composite polypropylene material for an automobile igniter shell. The composite polypropylene material comprises the raw materials in parts by weight: 95-105 of main materials, 2-8 of sodium alginate compound, 5-15 of polyester fibers, 4-10 of carbon nanotubes, 2-6 of bentonite, 1-6 of mica powder, 0.2-0.6 of phthalic anhydride, 0.5-1.2 of tert-butyl hydroperoxide, 0.2-0.6 of p-phenylenediamine, 1-2 of sodium dodecyl benzene sulfonate, 1-2 of coumarone resin, 0.1-0.4 of lanthanum oxide, 0.1-0.6 of praseodymium oxide and 2-4 of anti-aging agent. The sodium alginate compound is prepared by adopting the following process: mixing monomethoxyl polyethylene glycol, lactide and stannous iso caprylate; carrying out heating and stirring under the protection of nitrogen; carrying out filtration; adding sodium alginate, single-walled carbon nanotubes and water to be mixed; carrying out microwave treatment; carrying out centrifugation to remove solids; dropwise adding themixture into a calcium chloride solution which is in a stirring state; and carrying out filtration and vacuum drying.

Description

technical field [0001] The invention relates to the technical field of igniter casings, in particular to a composite polypropylene material used for automobile igniter casings. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic, resistant to various organic solvents and acid and alkali corrosion, widely used in the industry, and is one of the common polymer materials. Polypropylene is a thermoplastic resin obtained by the polymerization of propylene. It is non-toxic and odorless. According to the arrangement of methyl groups, it can be divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. It has the advantages of high strength, high hardness, wear resistance, excellent chemical resistance, easy processing and low price, etc., and is currently widely used in automobile igniter housing materials. [0003] However, the impact strength and tensile strength of polypropylene plastic can not meet the d...
