Problems solved by technology

[0003] For ultra-thin and large-sized mobile phones, the internal all-enclosed steel-plastic frame or half-enclosed steel-plastic frame is particularly important; however, the existing all-enclosed steel-plastic frame or half-enclosed steel-plastic frame generally has a poor reflection and light blocking effect. Poor, easy to warp and shrink, insufficient toughness, low strength and easy to break, easy to degumming

Abstract

The invention discloses high-strength PC (poly carbonate) which comprises the following components by weight percentage: 47.4-80.7% of PC resin, 3-7% of flexibilizer, 5-8% of TiO2, 0.2-0.4% of antioxidant, 0.1-0.3% of anti-drip agent, 0.3-0.5% of plasticizer, 0.5-1% of lubricant, 0.2-0.4% of coupling agent and 10-35% of glass fiber. PC with the component proportion can achieve high-reflection and high-light-resistance effects, is low in warpage, low in contractility and good in toughness, and does not rupture or degum.

Description

technical field [0001] The invention relates to the technical field of PC plastics, in particular to a high-strength PC. Background technique [0002] With the continuous development and progress of electronic technology, mobile phones are gradually becoming thinner. Among them, ultra-thin and large-sized mobile phones have gradually entered people's field of vision. [0003] For ultra-thin and large-sized mobile phones, the internal all-enclosed steel-plastic frame or half-enclosed steel-plastic frame is particularly important; however, the existing all-enclosed steel-plastic frame or half-enclosed steel-plastic frame generally has a poor reflection and light blocking effect. Poor, easy to warp and shrink, insufficient toughness, low strength and easy to break, easy to degumming. Contents of the invention [0004] The purpose of the present invention is to provide a high-strength PC for the deficiencies of the prior art. The high-strength PC can achieve the effect of hig...
