Abstract

The invention relates to an antibacterial polypropylene material and a preparation method thereof. The antibacterial polypropylene material is prepared from the following raw materials: homo-polypropylene resin, nanometer calcium silicate, a maleic anhydride grafted polypropylene homopolymer, a titanium dioxide dispersing agent, an antioxidant, salicylic acid phenyl ester, an 8-hydroxyquinoline Lacoordination complex, methyl ammonium iodide and ferrocene methyl alcohol; the preparation method comprises the following steps of pre-dispersion, mixing, squeezing and the like. The prepared antibacterial polypropylene is good in antibacterial effect, environment-friendly and non-poisonous, the mechanical strength and thermal deformation temperature are improved, and the shrinking percentage islowered.

Description

technical field [0001] The invention belongs to the field of modified plastics, in particular to an environment-friendly, non-toxic and durable antibacterial polypropylene material. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene. According to the arrangement position of the methyl group, it can be divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. [0003] When the methyl groups are arranged on the same side of the molecular main chain, it is called isotactic polypropylene. If the methyl groups are arranged randomly on both sides of the molecular main chain, it is called atactic polypropylene. When the methyl groups are arranged alternately on both sides of the molecular main chain, it is called interstitial polypropylene. Regular polypropylene. In the polypropylene resin produced in general industry, the isotactic structure content is about 95%, and the ...
