Abstract

The present invention relates to a flame-retardant styrene resin composition, which comprises the following components in weight part: 85-90 parts of styrene resin, 4-6 parts of halogen-based flame retardant, 1-2 parts of antimony-based flame retardant, 3-5 parts of phosphorus-based flame retardant, 0.1-0.2 part of antioxidant, and 0-2.0 parts of impact modifier. According to the technical scheme of the invention, under the synergistic effects of the antimony-based flame retardant, the phosphorus-based flame retardant and the halogen-based flame retardant, the flame-retardant efficiency of styrene resin is effectively improved. The flowability and the apparent quality of styrene resin are improved. Therefore, the problems in the prior art that styrene resin is difficult in injection molding and low in gloss can be solved. As a result, the flame-retardant styrene resin composition has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a flame-retardant styrenic resin composition and a preparation method thereof. Background technique [0002] At present, styrene resins are widely used in electronic appliances, automobile industry, office equipment, communication equipment, household appliances and other fields. They are flammable polymer materials. Flame retardant modification to meet its use requirements in terms of safety and fire prevention. At present, the most commonly used flame retardant system for styrene resins with the best effect is the synergistic system of halogenated flame retardants and antimony trioxide, which achieves flame retardancy through the mechanism of gas phase flame retardancy. The application of other types of flame retardants in styrene resins is less, the main reason is that the addition of other types of flame retardants such as phosphorus flame retardants will destroy...
