Abstract

The invention discloses a wear-resisting and break-resistant PC (polycarbonate) composite material for a mobile telephone shell. The wear-resisting and break-resistant PC composite material is prepared from raw materials in parts by weight as follows: 60-80 parts of PC, 25-40 parts of polylactic acid, 15-30 parts of organic silicon resin, 10-18 parts of polypropylene resin, 0.8-1.8 parts of poly-p-phenylene terephthamide, 1-3 parts of bamboo fiber, 4-8 parts of waterborne polyurethane, 1.5-3 parts of polysulfonamide, 10-15 parts of filler, 2-3 parts of sodium dihydrogen phosphate, 1-1.5 partsof zinc acetate and 0.8-1.5 parts of stannous chloride. The wear-resisting and break-resistant PC composite material for the mobile telephone shell is good in wear resistance and flame retardance, high in toughness and good in breaking resistance, and the service life of the mobile phone shell is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of mobile phone materials, in particular to a wear-resistant and drop-resistant polycarbonate composite material for a mobile phone shell. Background technique [0002] With the rapid development of communication technology, mobile phones have undergone several upgrades in just a few decades. As a powerful protective umbrella for the mobile phone, the mobile phone shell can effectively reduce the invasion of dust, reduce the damage caused by accidental drops, improve the service life of the mobile phone, and improve the user's product experience. Polycarbonate materials have become one of the commonly used materials for mobile phone casings due to their good mechanical properties and heat resistance. However, at present, polycarbonate materials have defects such as insufficient wear resistance, flame retardancy and drop resistance, which affect the service life of mobile phone casings. .
