Abstract

The invention discloses a plastic shell material for electronic equipment and a processing method thereof. The plastic shell material comprises the following raw materials by weight: 100 to 120 parts of polycarbonate, 50 to 60 parts of polystyrene, 35 to 40 parts of ABS plastic, 35 to 38 parts of C15-20 fatty primary amine, 20 to 23 parts of a biomass material, 22 to 25 parts of bamboo charcoal particles, 15 to 18 parts of zinc borate, 10 to 12 parts of starch, 18 to 20 parts of diatomite, 18 to 20 parts of vinyl bisstearamide, 10 to 13 parts of sodium dodecyl sulfate, 10 to 12 parts of glycerin, 10 to 12 parts of grease, 9 to 11 parts of a plasticizer, 8 to 10 parts of amine-terminated polyether, 8 to 10 parts of phosphonitrilic chloride, 8 to 10 parts of white carbon black, 8 to 10 parts of ginger oleoresin and 6 to 8 parts of pigment. The can release negative ions, overcomes the problem of great odor of plastic shells and has excellent resistance to wear and oxidation.

Description

technical field [0001] The invention relates to the field of plastic casing materials for electronic products. More specifically, the present invention relates to a plastic casing material for electronic equipment and a processing method thereof. Background technique [0002] Shells made of plastic shell materials are widely used in electronic products. For example, the shells of household consumer electronic products such as mobile phones, cordless phones, remote controls, etc. are all made of plastic shell injection molding, surface oil spraying, silk screen laser engraving or electroplating. . It has the advantage of simple process. At present, how to further optimize the plastic case material has become the focus of development and design. It is necessary to solve the problems of poor anti-aging performance of the plastic case material on the market, easy to become brittle and crack after a long time, and the bonding force between the plastic case material and other co...
