The high-hardness, wear-resistant and heat-resistant material comprises the following raw materials in parts by weight: 80-120 parts of modified ethylene propylene diene monomer, 30-50 parts of styrene-butadiene rubber, 30-50 parts of epoxy resin, 30-50 parts of coumarone resin, 20-50 parts of polycarbonate, 5-15 parts of wollastonite, 2-8 parts of nano calcium carbonate, 1-5 parts of magnesium carbonate, 3-6 parts of trioctyl trimellitate, 4-8 parts of 2,6-di-tert-butyl-4-methylphenol, 2-9 parts of dicumyl peroxide, 3-4 parts of phthalic anhydride, 2-6 parts of an anti-stress-cracking agent, 2-6 parts of a lubricant, 1-5 parts of a flame retardant, 2-6 parts of a foaming agent and 2-5 parts of a toughening agent. The high-hardness, wear-resistant and heat-resistant material for the cell phone cases, disclosed by the invention, is high in hardness and good in wear resistance and heat resistance.

Description

technical field [0001] The invention relates to a mobile phone casing material, in particular to a high-hardness wear-resistant and heat-resistant material for the mobile phone casing. Background technique [0002] At present, the plastic materials commonly used for mobile phone casings mainly include PC, ABS and PC+ABS. Japanese mobile phones mainly use PC+ABS, and even ABS is used for mobile phone casings. [0003] The hardness, wear resistance and heat resistance of the mobile phone shells in the prior art cannot meet the needs of actual production, so it is urgent to develop a material for mobile phone shells with high hardness, high wear resistance and high heat resistance. Contents of the invention [0004] In order to solve the technical problems in the background technology, the present invention proposes a high-hardness wear-resistant and heat-resistant material for a mobile phone shell, which has high hardness, good wear resistance and heat resistance. [0005] ...
