Flame retarding aging resistant plastic for mobile phone shell

Abstract

The invention discloses flame retarding aging resistant plastic for a mobile phone shell. The flame retarding aging resistant plastic is prepared from, by weight, 10-30 parts of styrene-butadiene-styrene copolymer, 15-30 parts of organic silicon resin, 5-18 parts of polypropylene, 5-15 parts of polyurethane, 5-15 parts of acrylnitrile-butadiene-styrene copolymer, 2-8 parts of boron nitride, 4-8 parts of Fe-OMT, 1-5 parts of aluminum oxide, 1-2 parts of titanate TTS, 2-8 parts of silicon carbide, 5-15 parts of calcined clay, 5-15 parts of clay, 8-16 parts of modified opal powder, 1-3 parts of polypropylene grafted maleic anhydride, 0.5-1.5 parts of polycaprolactone, 0.5-2 parts of natural rubber grafted poly methyl methacrylate, 0.5-1.5 parts of dithiodimorpholine, 1-2 parts of tert-butyl hydroperoxide, 1-2 parts of methylenebis(2-chloroaniline), 1-2 parts of poly-nitrosobenzene, 0.5-1.5 parts of 1,2-dihydro-2,2,4-trimethylquinoline homopolymer, 0.5-1.5 parts of 1-hexadecanol and 0.5-1.5 parts of distearyl thiodipropionate. The flame retarding aging resistant plastic is resistant to abrasion and aging and superior in flame retarding performance.

Description

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

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.
