Abstract

The invention relates to a flame-retardant ABS material and a preparation method thereof. The flame-retardant ABS material comprises the following raw materials in parts by weight: 50-55 parts of flowing ABS resin, 15-20 parts of a flame retardant, 10-12 parts of a synergistic aid, 1-2 parts of an antioxidant, 0.5-0.8 part of a light stabilizer and 4-6 parts of a processing aid; and the flowing ABS resin is used as a matrix, the flame retardant and the synergistic auxiliary agent synergistically exert effects, so that the flame-retardant material is endowed with excellent flame-retardant performance, halogen elements are not introduced, the flame-retardant material meets the environmental protection requirement, the molecular weight is increased, the branching degree is high, the flame retardant is not easy to separate out in the matrix, the flame-retardant performance is stable, the durability is high, by adding a small amount of the flame retardant, a matrix can be endowed with excellent flame retardant property, the damage to the physical property of the matrix material is reduced, and by adding an antioxidant and a light stabilizer, the weather resistance of the flame retardant material can be improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant ABS material and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-styrene-butadiene copolymer) resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. Dimensional stability, good surface gloss, etc., easy to paint and color, widely used in machinery, automobiles, electronic appliances, instrumentation, textiles and construction and other industrial fields, it is a thermoplastic engineering plastic with a wide range of uses. [0003] However, the oxygen index of ABS resin is only 18.3-20, which is a flammable material. Therefore, flame retardants must be added to products such as fire protection to meet the use requirements. At present, the common flame retardant modification method in the ma...
