Embodiment Construction
[0025] The present invention will be further described below in combination with specific embodiments.
[0026] 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.
[0027] 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 of the ASA material. The ASA material is composed of the following components: 60-70 parts of ASA resin, 12-15 parts of CPE resin, 10 parts of brominated epoxy resin, 3 parts of antimony trioxide, 2-3 parts of melamine polyphosphate and a derivative of the melamine polyphosphate, 4-6 parts of magnesium hydroxide crystal whiskers, 0.5 part of an anti-dripping agent, 0.5 part of a stabilizer, 0.5 part of a lubricant, and 0.5 part of hydrotalcite. At the same time, the invention discloses a preparation method of the 5VA-grade flame-retardant ASA material with excellent weather resistance, low smoke and environmental protection. The preparation method provided by the invention is simple, and the process operation is easy to realize, and the ASA composite material prepared by the method can meet the requirements for product safety in home appliance, automobile, electronic and electrical 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...
