Abstract

The invention discloses a high flame-retardant material for a mobile phone shell. The high flame-retardant material is prepared from the following raw materials in parts by weight: 65 to 75 parts of PC (polycarbonate), 27 to 33 parts of ABS (acrylonitrile butadiene styrene), 4 to 7 parts of compound compatilizer, 13 to 17 parts of compound flame retardant, 0.2 to 0.7 part of polytetrafluoroethylene, 0.5 to 1.2 parts of diisobutyl phthalate, 0.3 to 0.7 part of pentaerythritol stearate, 0.4 to 1 part of zinc stearate, 0.2 to 0.8 part of phosphate, and 0.3 to 0.8 part of 2,6-ditert butyl-4-methylphenol. The prepared high flame-retardant material has excellent flame-retardant property and flowing property.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a highly flame-retardant material for a mobile phone casing. Background technique [0002] Polycarbonate, referred to as PC, is a polymer whose main chain contains carbonate bonds. Polycarbonate can be roughly divided into two categories: one is aromatic carbonate, mainly bispan polycarbonate; Class is aliphatic polycarbonate. ABS resin is a complex phase structure composed of acrylonitrile, butadiene and styrene ternary copolymerization. It is a two-phase system composed of a dispersed phase and a continuous phase. The continuous phase is styrene-refined acrylonitrile copolymer (SAN ) resin whose dispersed phase is polybutadiene (PB) rubber particles. [0003] Mobile phone cases are mainly made of metal or plastic. The metal mobile phone case has the advantages of good texture and high strength, but it has problems such as high cost, difficult processing, signal pro...
