Abstract

The invention discloses high-light-resistance glass fiber reinforced PC plastic. The PC plastic comprises the following components in percentage by weight: 48%-88% of PC resin, 1%-5% of MBS, 1%-5% of EMA, 3%-30% of glass fiber, 5%-15% of TiO2, 0.2%-0.5% of a coupling agent, 0.1%-0.3% of an antioxidant, 0.3%-0.8% of a lubricating agent and 0.001%-0.5% of carbon powder. The PC plastic is high in light resistance, low in warping degree, stable in size and easy to demold.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a high-resistance glass fiber reinforced PC plastic and a preparation method thereof. Background technique [0002] In the prior art, the plastic frame of the backlight display module (such as the plastic frame of the mobile phone, LCD, TV, industrial control, vehicle backlight, etc.), and the lamp bottom case for LED lighting change the product assembly mode and reduce the product manufacturing process. Inject the plastic directly on the backlit iron frame (in the past, the plastic was made into a frame and bonded to the iron frame through an adhesive). This type of molding method is called plastic-iron integrated injection molding in the injection molding industry. During the preparation process of existing materials (materials from Japan, South Korea, Taiwan, etc.), this type of product prepared has a large shrinkage rate and low material strength, resulting in deformation and war...
