Abstract

The invention relates to an anti-impact polypropylene material, which is prepared from the following raw material ingredients including modified polypropylene, titanium dioxide quantum dots, antioxidants 1076 and calcium stearate, wherein the modified polypropylene is prepared from polypropylene, 1-butyl-3-methyl imidazole stearate, stearic acid and polyurethane resin through reaction. The 1-butyl-3-methyl imidazole stearate is prepared from stearic acid, 1-butyl-3-methyl imidazole acetate, 1-butyl-3-methyl imidazole chlorine salt and ethyl alcohol through reaction; the polyurethane resin is prepared from diphenylmethane diisocyanate, glycol, 1,4-butanediol, polycarbonate diol, polytetrahydrofuran ether diol, polyester polyol CM-580 and dibutyl tin laurate through reaction; the titanium dioxide quantum dots are prepared from tetrabutyl titanate, stearic acid, ethanol, KH-560 couplin agents and Tween 60 through reaction. The anti-impact polypropylene material has excellent impact intensity.

Description

technical field [0001] The invention relates to an impact-resistant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene has the advantages of greater rigidity, low density, high transparency, and heat resistance, but polypropylene has the disadvantage of low impact strength. Low impact strength limits the range of applications for polypropylene. Polypropylene is usually widely used in computer and mobile phone film, plastic food packaging, water delivery pipes, food boxes, municipal water supply and drainage pipes, automobile bumpers and other fields. [0003] At present, the impact strength of polypropylene materials needs to be further improved. The invention uses modified polypropylene, titanium dioxide quantum dots, antioxidant 1076, and calcium stearate to prepare an impact-resistant polypropylene material, and the impact-resistant polypropylene material prepared by the method has excellent impact strength.
