Embodiment 1

[0049] Take various raw materials according to the raw material formula of Table 1, wherein MBS resin (the weight percent content of methyl acrylate is 5~45%, butadiene content is 10~40%, styrene content is 15~60%), PMMA resin (Refractive index is 1.492, Vicat softening point is greater than 110°C, under the condition of 200°C / 5Kg, its melt index is 1.5-3.5g / min), SAN resin (refractive index is 1.56, the content of acrylonitrile should be lower than 15-24%, the Vicat softening point is greater than 105°C) and dried at 80°C for 3 hours before use, and various raw materials (including auxiliary materials) were added to a high-speed mixer and mixed at high speed for 2 minutes, and then discharged at a low speed. The mixed material was melted and granulated to obtain a high fluidity and high transparency ABS thermoplastic resin composition, and the test data of product properties are shown in Table 2. Melting and granulation conditions are: main engine screw speed 500r / min, feedin...

Abstract

The invention belongs to the technical field of polymer engineering plastics and particularly relates to an ABS (Acrylonitrile Butadiene Styrene) thermoplastic resin and a preparation method thereof. The invention solves the technical problem to provide an ABS thermoplastic resin with high fluidity and high transparency. The ABS thermoplastic resin is prepared from the raw materials in parts by weight: 20-75 parts of SAN (Styrene Acrylonitrile) resin, 20-60 parts of PMMA (Polymethylmethacrylate) resin, 2-25 parts of MBS (Methacrylate-butadiene-stryrene) resin, 0.2-04 part of antioxidant, 0.05-0.2 part of light stabilizer, 0.05-0.2 part of whitening agent and 0.05-0.2 part of lubricant. The ABS thermoplastic resin has the advantages of good surface glossiness, good rigidity, good transparency, good mechanical property and good forming and processing property, and each key index of the ABS thermoplastic resin exceeds that of commonly used transparent plastics such as transparent ABS and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer engineering plastics, in particular to ABS thermoplastic resin and a preparation method thereof. Background technique [0002] ABS resin (acrylonitrile-butadiene-styrene) is a new general-purpose thermoplastic engineering plastic developed in the 1940s. It has excellent electrical properties, chemical resistance, impact resistance, low temperature resistance, cold resistance, Surface gloss, coloring performance and dimensional stability, easy to process and shape, the product has excellent gloss, and has both toughness and flexibility. Therefore, ABS resin is widely used in household appliances, industrial spare parts, casings and transmission parts of electronic and electrical products, office supplies, instruments and meters and other fields. [0003] With the continuous innovation of product appearance design and the continuous improvement of technological level, the research and application o...
