Problems solved by technology

[0004] The Chinese patent application number 201310022160.1 discloses a high-gloss ABS alloy and a method for preparing the alloy by using matt ABS. It adds 20-60% AS and 0.2-2% light stabilizer to prepare a high-gloss ABS alloy material , the gloss is much higher than that of ordinary ABS, but it is not a flame-retardant material, and its impact resistance is much lower than that of ordinary ABS; the Chinese patent application number 200810203577.7 discloses a high-gloss alloy material, which has added 30 %~60% PMMA and 4%~15% MBS, the gloss has been greatly improved, but its flame retardancy is not ideal, and it also has defects such as poor impact resistance and easy stress cracking.

preparation example Construction

[0021] A preparation method of flame-retardant ABS alloy material, comprising the following steps:

[0022] 1) Weigh the raw materials ABS resin, AS resin, white oil, toughening agent, brominated flame retardant, flame retardant synergist, antioxidant and lubricant according to the formula ratio;

[0023] 2) First put ABS resin, AS resin and white oil in a high-speed mixer and stir for 1~3min, then add other raw materials and mix for 1~3min;

[0024] 3) Add the mixture after step 2) into a twin-screw extruder for extrusion granulation, and after cooling, dehydration, and drying processes, a flame-retardant ABS alloy material with high gloss and strong impact resistance is obtained, wherein , The extrusion temperature is 190~210°C.

Abstract

The invention discloses an anti-flaming acrylonitrile-butadiene-styrene (ABS) alloy material, comprising the following raw materials by mass percent: 50-70% of ABS resin, 8-20% of AS resin, 0.1-0.3% of white oil, 5-20% of flexibilizer, 10-15% of brominated flame retardant, 3-6% of flame retardant synergist, 0.2-0.5% of antioxidant and 0.2-0.5% of lubricant, wherein the flexibilizer is methyl methacrylate-butadiene-styrene ternary copolymer powder of which the grain size is 50-300nm; the brominated flame retardant is one or more than one of tetrabromobisphenol A, decabromodiphenylethane, brominated epoxy resin and tri-cyanurate; the flame retardant synergist is nanoscale antimony trioxide of the grain size is 0.5-100nm. By adopting the anti-flaming ABS alloy material disclosed by the invention, the flame retardance of the material is considered when high glossiness and high impact resistance are achieved; the incident angle when the glossiness is 20 degrees reaches over 99.6 GU.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant ABS alloy material with high gloss and high impact resistance, and also relates to a preparation method of the flame-retardant ABS alloy material. Background technique [0002] ABS resin is a multi-component copolymer produced by the copolymerization of acrylonitrile, butadiene and styrene. Due to its excellent performance and beautiful appearance, it is widely used in the fields of electronics, electrical appliances, construction, electromechanical, instruments and instruments. It is widely used and occupies a large part of the entire resin market. [0003] With the development of society, people have higher and higher requirements for products. In the case of similar performance, they prefer products with beautiful appearance. Therefore, there is high-gloss ABS, which is used in LED display frames and bases, and refrigerators. There are many daily necessities...
