Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The composition of the raw materials of the ASA composite materials prepared in Examples 1-5 and Comparative Examples 1-8 is shown in Table 1, and the preparation method is as follows: After drying each raw material at 80°C for 4 hours, add it to a high-speed mixer, and adjust the speed of the mixer to 500r / min, stirred for 5 min, then transferred to a twin-screw extruder, extruded, cooled, granulated, and dried to obtain an ASA composite material.

[0028] The ASA composite material was first dried (85°C for 3h), and then injection molded (injection temperature was 200°C) as a standard test sample for performance testing. The test results are shown in Table 2.

Abstract

The invention relates to the field of polymer materials, and discloses a 5VA grade flame-retardant ASA material with excellent weather resistance, low smoke and environmental protection and a preparation method thereof, which consists of 60-70 parts of ASA resin, 12-15 parts of CPE resin, brominated epoxy 10 parts, 3 parts of antimony trioxide, 2-3 parts of melamine polyphosphate and its derivatives, 4-6 parts of magnesium hydroxide whiskers, 0.5 parts of anti-dripping agent, 0.5 parts of stabilizer, 0.5 parts of lubricant, water Composed of 0.5 parts of talc. At the same time, a preparation method of the low-smoke and environment-friendly 5VA grade flame-retardant ASA material with excellent weather resistance is also disclosed. The preparation method of the invention is simple, and the process operation is easy to realize, and the prepared ASA composite material can meet the product safety requirements of household appliances, automobiles, and electronic and electric industries.

Description

technical field [0001] The invention relates to a polymer material, in particular to a 5VA grade flame-retardant ASA material with excellent weather resistance, low smoke and environmental protection and a preparation method thereof. Background technique [0002] ASA resin, as a new variety in the ABS resin series, is a graft copolymer composed of acrylonitrile-styrene-acrylate. Compared with ABS, due to the introduction of acrylate rubber without double bonds to replace polybutadiene rubber with double bonds, the weather resistance of ASA has been fundamentally changed, and the mechanical strength of ABS resin has been significantly improved after long-term exposure outdoors. Decline, the color gradually turns yellow under the action of sunlight, etc. [0003] ASA resin is a combustible material, which belongs to the HB level according to the UL94 standard. When it catches fire, it will emit a large amount of poisonous gas and black smoke, which will pose a great threat to...
