Matt polycarbonate styrene resin alloy and preparation method thereof

Abstract

The invention relates to a matt polycarbonate styrene resin alloy. The matt polycarbonate styrene resin alloy contains following raw material constituents of, by weight part, 50-80 parts of polycarbonate resin, 15-48 parts of polycarbonate resin, 2-5 parts of isocyanate chemical compounds, 0.5-2 parts of compatible agent and 0.5-1 part of processing agent. A preparation method of the matt polycarbonate styrene resin alloy includes following steps: mixing the above raw material constituents in a high speed mixer in advance for 3-10min, and then extruding and granulating the premixed materials through a double screw extruder under 230-280 degree centigrade so as to obtain the matt polycarbonate styrene resin alloy. The matt polycarbonate styrene resin alloy has the advantages that compared with the prior art, no matt master particle needs to be prepared, the polycarbonate styrene resin alloy excellent in matt effect can be directly prepared through a one step method, and the preparation method of the matt polycarbonate styrene resin alloy is simple in technical process, solves the technical problems that glossiness distribution is uneven, physical and mechanical properties are deteriorated, preparation technology is complex and the like, and can reduce cost.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer material processing, in particular to a matte polycarbonate styrene resin alloy and a preparation method thereof. 【Background technique】 [0002] Polycarbonate styrene-based resin alloys have been widely used, and matte 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 i...

AI Technical Summary

Problems solved by technology

[0009] However, the above-mentioned technical solutions often have deficiencies such as insufficient matteness, large fluctuations in physical and mechanical properties, uneven gloss of the product, and high cost. These defects especially greatly limit the use of polycarbonate styrene resin alloys in automobiles. Applications in the field of accessories

But about a kind of matte polycarbonate styrenic resin alloy with simple process, ultra-low gloss, excellent physical and mechanical properties and its preparation method, there is no report yet
