Plastic for flame-retardant, wear-resistant and aging-resistant mobile telephone shell

Abstract

The invention discloses a plastic for a flame-retardant, wear-resistant and aging-resistant mobile telephone shell. The plastic comprises the following raw materials in parts by weight: 10-18 parts of polycarbonate, 5-18 parts of polypropylene, 20-40 parts of an ethylene-octene copolymer, 15-25 parts of polyvinyl chloride, 8-16 parts of a maleic anhydride grafted ethylene-ninyl acetate copolymer, 2-8 parts of silicon carbide, 1-2.5 parts of a silane coupling agent SI-69, 1-4 parts of aluminum oxide, 2-10 parts of iron-based montmorillonite, 1-3 parts of boron nitride, 8-12 parts of nanosilicon dioxide, 5-16 parts of modified opal powder, 8-14 parts of calcined kaolin, 1-3 parts of phenylene maleic imide, 1-3 parts of natural rubber grafted polymethyl methacrylate, 1-3 parts of caprolactam, 1-2 parts of benzoyl peroxide, 0.2-0.6 part of triethylenetetramine, 0.2-0.6 part of cyclohexanone peroxide, 1-2 parts of t-butyl perbenzoate, 1-3 parts of octadecyl alcohol, 1-3 parts of p-phenylenediamine and 1-3 parts of trioctyl. The plastic disclosed by the invention is wear-resistant, aging-resistant, and excellent in flame retardance.

Description

technical field [0001] The invention relates to the technical field of mobile phone shells, in particular to a flame-retardant, wear-resistant and aging-resistant plastic for mobile phone shells. 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 ...

Problems solved by technology

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.
