Low-smoke flame-retardant acrylonitrile butadiene styrene (ABS) alloy material

Abstract

The invention relates to the technical field of the high polymer material, in particular to a low-smoke flame-retardant acrylonitrile butadiene styrene (ABS) alloy material. The ABS alloy material comprises the following components in percentage by weight: 50-90% of ABS resin, 0.1-30% of brominated flame retardant, 0.1-10% of auxiliary flame retardant, 0.1-20% of toughening agent, 0.01-1% of anti-dripping agent, 0.01-1% of antioxidant and 0.01-1% of lubricating agent. The auxiliary flame retardant in the low-smoke flame-retardant ABS alloy material is antimony sodium silicon composite flame retardant, zinc borate, aluminium magnesium carbonate compound and antimonous oxide or combination of several of the antimony sodium silicon composite flame retardant, the zinc borate, the aluminium magnesium carbonate compound and the antimonous oxide. According to the auxiliary flame retardant, the use amount of antimony white can be lowered, the production cost of the flame-retardant ABS alloy material is lowered, the smoke release rate and the smoke release amount in the material burning process are lowered, and the low-smoke flame-retardant ABS alloy material has the advantages of good flame-retardant effect and obvious social benefit and industrial application value.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-smoke flame-retardant ABS alloy material. Background technique [0002] ABS resin is a terpolymer synthesized from acrylonitrile, butadiene, and styrene as monomers. It has high impact strength, high heat resistance, chemical corrosion resistance, low temperature impact resistance, good electrical insulation performance, and excellent dimensional stability. It has excellent characteristics such as small molding shrinkage rate and excellent processing performance.

Chinese patent CN101463177B discloses a preparation method of a high-gloss flame-retardant ABS modified resin. This method improves the flame retardancy of ABS while improving its surface gloss. The flame retardants used are brominated flame retardants and antimony The combination of white, CN102079842A discloses a preparation method of ultra-high flow flame retardant ABS modified resin, which improves the problem of poor fluidity of flame retardant ABS alloy materials due to the addition of flame retardants, and the used flame retardant The flame retardant is still a combination of brominated flame retardants and antimony white

[0004] Although the flame-retardant ABS alloy material prepared by using brominated flame retardants and antimony trioxide can meet the requirements of UL V0 according to the standard, it will release A lot of smoke, and in the course of a fire, 80-90% of the victims are suffocated by the smoke released during the burning process
