Abstract

The invention relates to a PC (polycarbonate)/ABS composition capable of improving the photocorrosion phenomenon of an air conditioner panel and a preparation method thereof. The PC/ABS composition consists of the following raw materials in parts by weight: 30-90 parts of PC, 10-70 parts of ABS, 0.1-1 part of titanium dioxide, 0.1-1 part of an antioxidant, 0.1-2 parts of a lubricant and 0-1 part of an additive; and the additive consists of a UV adsorbent and a colorant. The preparation method comprises the following steps: stirring the raw materials in a high-speed mixer according to a ratio; uniformly mixing, and then conveying into a twin-screw extruder by a metering device; with the conveying, shearing and mixing of screws, melting and compounding the materials; and performing extrusion, bracing, cooling and grain-sized dicing to obtain the PC/ABS composition. The materials of the PC/ABS composition provided by the invention are proper, and the prepared PC/ABS material can remarkably improve the photocorrosion phenomenon when used as the air conditioner panel.

Description

technical field [0001] The invention relates to the technical field of modified resins, in particular to a PC / ABS composition capable of improving the photocorrosion phenomenon of an air-conditioning panel and a preparation method thereof. Background technique [0002] At present, people's demand for air-conditioning products has already broken through the limitations of the basic functions of the products. Whether the appearance of the products is beautiful and whether they are harmonious and unified with the home environment has become one of the main factors that people consider when purchasing household appliances. On the other hand, the three major technological development trends of frequency conversion, energy saving, and environmental protection lack support in the current industry environment, and their development is relatively slow. However, the change of product appearance brought about by the fine-tuning of basic technologies is becoming an irresistible trend. I...
