Abstract

The invention relates to the field of polymer composite materials, in particular to a transparent low-temperature-resistant scuffing-resistant polycarbonate composite material. The polycarbonate composite material is prepared from, by weight, 300-800 parts of bisphenol A polycarbonate resin, 100-500 parts of siloxane copolymerized PC resin, 10-50 parts of organosilicone flexibilizer, 50-200 parts of surface hardness improving agent, 10-100 parts of nanometer scuffing-resistant master batch and 5-15 parts of additive. The siloxane copolymerized PC, the surface hardness improving agent and the nanometer scuffing-resistant master batch are composited for use, on the basis that the luminousness and the basic mechanical properties of PC are uninfluenced, the surface hardness and the low-temperature properties of the material are improved, the surface hardness can be increased to 2 H, the abrasion resistance of the surface of a product is obviously improved, and the surface glossiness and the weather resistance are also improved. Moreover, the surface tension of the product can be increased, and the product is easier to clean; the composite material is good in mechanical property, high temperature impact property and low temperature impact property.

Description

technical field

[0001] The invention relates to the field of polymer composite materials, in particular to a transparent low-temperature-resistant and scratch-resistant polycarbonate composite material and a preparation method thereof. Background technique

[0002] Polycarbonate is a plastic with good transparency. It has excellent comprehensive properties and is widely used. Its products are widely used in electronic appliances, automobiles, machinery manufacturing, computers and other technical fields.

[0003] However, the surface scratch resistance of polycarbonate material is poor, which greatly reduces the aesthetics of the product, and the scratches on the surface of the product will also lead to stress concentration. Usually used PC material products, in order to protect the appearance , generally to do coating treatment. In order to improve the scratch resistance of polycarbonate, there are patent reports to modify it by adding PMMA, carbon fiber, glass fiber, woll...
