the invention uses mineral filler and halogen flame retardant to realize that CTI required by household appliances achieves the index of 600V, and can enable the impact toughness to reach the level of common flame-retardant ABS on the market on the premise of achieving flame retardance V0. Meanwhile, the antimony trioxide is cooperated with the halogen flame retardant to have better flame retardant effect.
Specifically, the toughening agent is P/D181 powder of the Hanjin lake, and the relative molecular mass is 120000 g/mol.
Furthermore, the particle size of the antimony trioxide is 0.7-0.9 um. The antimony flame retardant with the particle size has good flame retardant effect and better synergistic effect with halogen flame retardant. If the particle size of the antimony trioxide particles is too small, the antimony trioxide particles are not easy to disperse, and if the particle size is too large, the flame-retardant synergistic effect is poor.
Further, the halogen flame retardant is brominated triazine and/or decabromodiphenylethane. The two halogen flame retardants have small influence on the toughness of ABS, and simultaneously have high flame retardant efficiency and good flame retardant effect in cooperation with antimony trioxide.
Further, the mineral filler comprises one or more of talcum powder, kaolin or montmorillonite. The mineral fillers have high metal ion content, are easier to conduct heat, can conduct heat and obviously improve CTI.

The mineral filler with the particle size characteristic has good synergistic flame retardant effect and small influence on the impact property of the ABS material.
Furthermore, the relative molecular mass of the SAN resin is 80000-120000 g/mol, wherein the styrene content is 70-75%, and the acrylonitrile content is 25-30%. The SAN resin with the characteristics has good processability and easy toughening, and if the molecular weight of the SAN resin is too low, the toughening efficiency is poor, and if the molecular weight of the SAN resin is too high, the processability is poor.
Further, the flame-retardant ABS material with high CTI and high impact comprises the following components in parts by weight:
0.1-1 part of antioxidant;
1-2 parts of a lubricant;
0.1-0.5 part of anti-dripping agent.
Further, the antioxidant is one or more of 2, 6-di-tert-butyl-4-methylphenol, dilauryl thiodipropionate, distearyl thiodipropionate, tris (2, 4-di-tert-butylphenyl) phosphite, bis (2, 4-di-tert-butyl) quarternary alcohol diphosphite and pentaerythritol diphosphite dioctadecyl alcohol; the lubricant is one or more of ethylene bis stearamide, stearate and silicone lubricant, and can effectively improve the processing performance of the material; the anti-sag agent is SAN coated PTFE which has good compatibility with ABS resin and is easy to process.
The preparation method of the flame-retardant ABS material with high CTI and high impact comprises the following steps:
(1) adding the raw materials except the halogen flame retardant and the mineral filler into a mixing stirrer according to a formula ratio for mixing to obtain a mixture;
(2) and (2) putting the mixture obtained in the step (1) into a main feeding port of a double-screw extruder, putting the halogen flame retardant and the mineral filler into feeding ports on two sides of the extruder, and performing blending granulation by the double-screw extruder to prepare the flame-retardant ABS particles with high CTI and high impact.
