Problems solved by technology

However, the flame retardancy of ABS resin itself is extremely low, the oxygen index is only about 18, and the vertical burning test cannot meet the UL94V-2 standard. Legislative and environmental protection requirements, the flame retardancy of materials is developing towards the trend of halogen-free and low toxicity, which puts forward higher requirements for the flame-retardant modification of ABS resin, which itself is difficult to flame-retardant.
[0003] There are many reports on the flame retardant treatment of ABS resin by using phosphonate compounds, but the common problem is that the flame retardant efficiency is not good, and there is no flame retardant used in conjunction with it

Embodiment 1

[0021] The components and parts by weight of the novel halogen-free flame-retardant ABS resin of the present invention are shown in Table 1, and the physical properties are shown in Table 2. Among them, the ABS resin is 8391 of DOW Company, the PPE is S202A of Asahi Kasei Company, the TPP is the product of Dahachi Chemical Company, the epoxy resin is E-51 of Shanghai Resin Co., Ltd., and the antioxidant is 1010 of ciba refinement.

[0022] The preparation method is as follows: the first step is to mix ABS resin, polyphenylene ether, phosphonate, epoxy resin, light and heat stabilizer and other components uniformly through high-speed stirring; the second step is to feed the above mixture The feeder is fed into the extruder, fully melted and compounded under the conveying and shearing action of the screw, and then extruded through the machine head, drawn, cooled, pelletized, and finally packaged.

[0023] The aspect ratio of the twin-screw extruder used in the preparation method...

Abstract

The halogen-free flame retardant ABS resin consists of ABS resin 100 weight portions, polyphenylene oxide 2-30 weight portions, phosphonate 5-20 weight portions, epoxy resin 1-10 weight portions, light and heat stabilizer 0.2-2 weight portions and processing assistant 1-5 weight portions. The halogen-free flame retardant ABS resin has the excellent performance of ABS resin maintained, flame retardant property, and the synergistic flame retarding effect of different flame retardant components. The preparation process of the halogen-free flame retardant ABS resin is also disclosed.

Description

technical field [0001] The invention relates to a flame retardant resin, and also relates to a preparation method of the flame retardant resin. Background technique [0002] ABS resin is a thermoplastic with excellent performance, which has high impact strength, heat resistance and dimensional stability. Due to its various advantages, it is widely used in industrial parts, housings and transmission parts of electronic and electrical products. and other fields. However, the flame retardancy of ABS resin itself is extremely low, the oxygen index is only about 18, and the vertical burning test cannot meet the UL94V-2 standard. Legislative and environmental protection requirements, the flame retardancy of materials is developing towards the trend of halogen-free and low toxicity, which puts forward higher requirements for the flame-retardant modification of ABS resin, which itself is relatively difficult to flame-retardant. [0003] There are many reports on the flame retardan...
