Abstract

The invention provides a special impact-resistant polystyrene material for new-energy vehicles and a preparation method of the material and relates to the technical field of high-polymer materials. The special impact-resistant polystyrene material for the new-energy vehicles is prepared from the following raw materials: high-impact-resistance polystyrene resin, acrylate epoxy resin, polyurethane elastomers, modified fibers, graphene oxide, nano talc, triphenyl phosphate, isophorone diisocyanate, tris(2,4-di-tert-butyl-pheny)phosphite, silicone oil, a plasticizer and a toughening agent. The special impact-resistant polystyrene material for the new-energy vehicles has the relatively high impact resistance, tensile strength, heat resistance and bending resistance and can keep the excellent impact resistance in the relatively wide temperature spectrum range.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an impact-resistant polystyrene material specially used for new energy vehicles and a preparation method thereof. Background technique [0002] With the continuous development of my country's economic construction and the continuous improvement of people's living standards, automobiles have entered the family, and the demand for oil is also increasing. The fuel of my country's automobiles mainly comes from oil, and the demand for oil is increasing. Because of the limited oil reserves, the oil faces the danger of depletion, and it also seriously pollutes the environment. For this reason, the country advocates the development of various new energy vehicles. [0003] High impact polystyrene resin is one of the cheapest engineering plastics. Compared with acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), PC / ABS, the gloss of the material is compared Poor...
