High toughness PC/ABS alloy material

Abstract

The invention discloses a high toughness PC/ABS alloy material, which comprises the following materials by weight: 40-50 parts of PC, 60-80 parts of ABS, 10-20 parts of a halogen-free intumescent flame retardant, 10-15 parts of an ethylene copolymer elastomer, 10-13 parts of nano-calcium carbonate, 12-15 parts of ethylene-acrylate, 1-5 parts of trimethylsilyl dimethyl methylphosphonate, 2-8 parts of melamine cyanurate, 5-8 parts of molybdenum trioxide, 2-8 parts of ammonium polyphosphate, 1-2 parts of stearic acid, 1-5 parts of stearate, 1-3 parts of stearamide, 1 part of silicone oil, 2 parts of tourmaline mineral micro-powder, 1-2 parts of poly-4-methyl-1-pentene, 5 parts of active calcium, 6 parts of stearic acid, 2-9 parts of a processing stabilizer, and 3-5 parts of a lubricant. According to the invention, the notch impact strength of a flame retardant PC/ABS material can be effectively improved, thus obtaining the high toughness flame retardant PC/ABS alloy material, which can be more adaptable to various high-tech manufacturing industries and has considerable economic benefits.

Description

technical field [0001] The invention relates to a PC / ABS alloy material with high toughness. Background technique [0002] PC / ABS is a plastic alloy material with excellent performance. It not only has good mechanical properties and molding processing properties, but also has good surface gloss and beautiful appearance, so it is widely used in electronics, home appliances and other industries. When PC / ABS alloy materials are used to manufacture electronic components, the materials are often required to have flame retardant properties. In this regard, people usually use the method of adding flame retardants to improve the flame retardant properties of materials. However, the addition of flame retardants will lead to a decrease in the notched impact strength of the PS / ABS alloy material, and the toughness of the material needs to be improved. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a PC / ABS alloy material with h...
