Abstract

The invention discloses a PC / ABS alloy, which comprises the following parts: 40-60% PC, 25-40% ABS, 2-5% compatible agent, 3-8% full acroleic acid core-shell impact modifier, 6-15% bromine-system fire retardant, 2-5% antimony-system fire retardant, 0.2-0.5% polytef, 0.1-0.3% lubricant. The invention improves the notch impact strength with high-toughness flame-proof PC / ABS alloy material, which has observable economic benefit.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a plastic alloy material. 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. [0003] 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 [0004] In view of the above problems, the object of th...
