Abstract
The invention relates to the field of high-polymer materials, and discloses a high-CTI (comparative tracking index)-value brominated flame-retardant HIPS (high impact polystyrene) material. The brominated flame-retardant HIPS material comprises the following raw materials in parts by weight: 51-66 parts of HIPS resin, 10-20 parts of brominated flame retardant, 2-5 parts of flame-retardant synergist, 10-20 parts of magnesium-containing compound, 5-10 parts of toughener, 0.4-1 part of antioxidant and 0.5-1 part of lubricant. The invention also discloses a preparation method of the brominated flame-retardant HIPS material. The brominated flame-retardant HIPS material provided by the invention has high CTI value and favorable tracking resistance; the flame retardancy is stable and can be up to the V-0 level; and the brominated flame-retardant HIPS material has excellent mechanical property and fine processability. Thus, the brominated flame-retardant HIPS material can be widely used for electronic/electrical equipment manufacturing.
Description
technical field [0001] The invention relates to the field of polymer materials, in particular to a brominated flame-retardant HIPS material with a high CTI value and a preparation method thereof. Background technique [0002] High-impact polystyrene (HIPS) is one of the cheapest engineering plastic varieties. It is easy to process and has excellent comprehensive performance. It is widely used in household appliances, office appliances, daily appliances and other components. Due to superior performance and low price, more and more HIPS are used. With the progress of society and the continuous improvement of use requirements and safety awareness, more and more attention has been paid to the flame retardancy and electrical safety performance of plastic products. [0003] The raw materials of HIPS are flammable materials, and the oxygen index is about 19%. The relative leakage index (CTI) of traditional flame-retardant HIPS is low, and it is difficult to meet the increasingly st...
