Abstract

The invention relates to a polycarbonate styrene resin alloy and a preparation method thereof. The polycarbonate styrene resin alloy comprises the following raw material components in parts by weight:30-60 parts of polycarbonate resin, 25-60 parts of styrene resin, 5-30 parts of branched polycarbonate, 5-15 parts of assistant crosslinking resin and 0.5-1.0 part of a processing aid. The preparation method comprises the following steps: premixing the raw materials in a high-speed mixer for 3-10 min, and carrying out extrusion granulation on the premix through a double-screw extruder at the temperature of 230-280 DEG C to obtain the ultralow-gloss polycarbonate styrene resin alloy. Compared with the prior art, the polycarbonate styrene resin alloy with ultralow gloss is directly prepared bya one-step method without preparing low gloss master batch, the preparation method and the technological process are simple, the problems of insufficient gloss, uneven gloss distribution, deterioration of physical and mechanical properties, complex process, high cost and the like are solved, and the resin alloy is particularly suitable for the field of automotive interiors.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a polycarbonate styrene resin alloy and a preparation method thereof. Background technique [0002] Polycarbonate styrene-based resin alloys have been widely used, and low-gloss surface effects are expected in some fields such as electronic appliances and automotive interior parts, such as computer casings, keyboards, mice, and instruments in automotive interior parts. panels, sun visors, navigator frames, etc. Especially in the field of automotive interiors, in order to avoid the visual disturbance caused by the reflection of sunlight on the driver and reduce the driver's visual fatigue, so as to achieve the purpose of safe and comfortable driving, matting or matte treatment is generally carried out to reduce the interior as much as possible. surface gloss of the piece. Generally, there are mainly the following methods to reduce the surface gloss of interio...
