Problems solved by technology

However, the modified PC / PET alloy resin is difficult to make the blackness meet the high black requirement and the gloss is not enough
In order to make PC / PET alloy resin achieve spray-free effect, it requires high gloss, color and wear resistance. Generally, PC / PET alloy resin cannot achieve spray-free effect, and when PC / PET alloy resin is used When it comes to automotive trim, the wear resistance is still not as good as that of painted parts

Abstract

The invention discloses high-glossiness and high-blackness spraying-free PC / PET alloy resin and a preparation method thereof. Preparation raw materials for the PC / PET alloy resin comprise the following components: 50 to 70 weight parts of PC, 30 to 50 weight parts of PET, 1.3 to 2 weight parts of a silicone wear-resisting agent, 0.5 to 1 weight part of a lubricating agent, 0.2 to 1 weight part ofa coupling agent, 0.2 to 0.8 weight part of an antioxidant, 1 to 1.2 weight parts of solvent purple, 0.5 to 0.7 weight part of solvent yellow and 0.3 to 0.5 weight part of solvent orange. The PC / PET material prepared through the preparation method disclosed by the invention finally solves the problems that the PC / PET coloring blackness is insufficient and the wear resistance is low; meanwhile, asa spraying-free product, the PC / PET material reduces the spraying cost and improves environmental pollution.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a PC / PET alloy resin and a preparation method thereof, in particular to a high wear-resistant PC / PET alloy resin with high gloss, high black and spray-free effect and a preparation method thereof. Background technique [0002] PC (polycarbonate) is a strong thermoplastic polymer, colorless, transparent, heat-resistant and impact-resistant, has good mechanical properties in the temperature range of use, and has good processing performance, but PC has poor wear resistance and water resistance solution stability is poor. After trying to modify PC, it is found that PC / PET alloy resin has good mechanical properties, super toughness and the wear resistance of PC has increased to a certain extent. [0003] Generally, the surface treatment method of automotive interior and exterior materials is generally spraying or electroplating, and most of the interior and exterior materials of automo...
