Abstract

The invention relates to an ABS composite plastic and a preparation method thereof. The ABS composite plastic is composed of the following components according to the weight ratio: 40-46 parts of ABS resin, 12-14 parts of melamine-formaldehyde resin, 5-8 parts of urea-formaldehyde resin, poly 2-4 parts of butyl methacrylate, 3-4 parts of diethyl phosphate, 4-7 parts of methyl orthosilicate, and 5-7 parts of propanol. The preparation process of the ABS composite plastic of the present invention includes steps such as heating, stirring, mixing, and extrusion molding. The prepared ABS composite plastic has excellent flame retardancy and acid resistance, can be used in an acidic environment, and can prevent the plastic from burning.

Description

technical field [0001] The invention relates to a composite plastic and a preparation method thereof, in particular to a flame-retardant and acid-resistant ABS composite plastic and a preparation method thereof. Background technique [0002] ABS plastic is one of several major synthetic plastics. ABS plastic has excellent impact resistance, heat resistance, chemical stability and so on. ABS plastic is a terpolymer of acrylonitrile, butadiene and styrene. Because of its good impact resistance, it can be used in some mechanical equipment and parts, and has good performance. Conventional ABS plastics have poor acid resistance. After contacting acid, ABS plastics will be chemically destroyed, which affects the normal use of ABS plastics. In addition, the flame retardant effect of conventional ABS plastic is relatively common. [0003] Since conventional ABS composite plastics do not have good acid resistance and flame retardancy, improving the acid resistance and flame retarda...
