Wear-resistant composite plastic for shells of mobile phones

Abstract

The invention discloses wear-resistant composite plastic for shells of mobile phones. The wear-resistant composite plastic is prepared from raw materials in parts by weight as follows: 15-25 parts of polypropylene, 10-18 parts of polycarbonate, 20-30 parts of epoxy resin, 10-20 parts of polyethylene, 15-30 parts of a maleic anhydride grafted ethylene-vinyl acetate copolymer, 2-6 parts of alumina, 1-5 parts of carbon nano tubes, 1-5 parts of boron nitride, 2-10 parts of Fe-based montmorillonoid, 0.5-1.8 parts of a silane coupling agent KH-550, 10-30 parts of modified opal powder, 15-35 parts of fly ash, 5-18 parts of nano-carbon black, 1-2 parts of polycaprolactone, 1-2 parts of polypropylene grafted maleic anhydride, 1-2 parts of chlorinated polyethylene, 0.5-1.2 parts of phenol formaldehyde resin, 0.5-1.2 parts of a 2,4-toluene diisocynate bipolymer, 1-3 parts of zinc diethyl dithioformate, 0.1-0.5 parts of dicumyl peroxide, 1-2 parts of diphenylamine, 1-2 parts of thiodipropionic acid diester and 1-2 parts of bis(2,2,4-trimethyl-1,3-pentanediol monoisobutyrate). The wear-resistant composite plastic is excellent in wear resistance, ageing resistance and flame retardance.

Description

technical field [0001] The invention relates to the technical field of mobile phone shells, in particular to a wear-resistant composite plastic for a mobile phone shell. Background technique [0002] The mobile phone case is particularly important as a component to protect the core components inside the mobile phone. The existing mobile phone cases are generally made of metal or plastic. The mobile phone case made of metal has the advantages of high hardness, high strength, and metal texture, while the mobile phone case made of plastic has the advantages of light weight, rich colors and corrosion resistance. Among them, the mobile phone case made of plastic, compared with the mobile phone case made of metal, due to the simple manufacturing process and low cost, the plastic mobile phone case is widely used in actual production, but the existing plastic mobile phone Compared with the metal mobile phone case, the shell has poor wear resistance, aging resistance and flame retar...

The existing mobile phone cases are generally made of metal or plastic. The mobile phone case made of metal has the advantages of high hardness, high strength, and metal texture, while the mobile phone case made of plastic has the advantages of light weight, rich colors and corrosion resistance. Among them, the mobile phone case made of plastic, compared with the mobile phone case made of metal, due to the simple manufacturing process and low cost, the plastic mobile phone case is widely used in actual production, but the existing plastic mobile phone Compared with the metal mobile phone case, the shell has poor wear resistance, aging resistance and flame retardancy, which will shorten the life of the plastic mobile phone case.
