Electroplating polypropylene alloy material and preparation method thereof

Abstract

The invention discloses an electroplating polypropylene alloy material and a preparation method thereof. The electroplating polypropylene alloy material is prepared from 620-700 parts of polypropylene, 50-80 parts of acrylnitrile-butadiene-styrene copolymer, 10-50 parts of compatilizer, 200-300 parts of inorganic filler, 4-8 parts of antioxidant, 4-6 parts of lubricant and 2-3 parts of bridging agent by mixing and extrusion pelletization. The prepared electroplating polypropylene alloy material has good electroplating appearance and coating strength, the cost can be replaced, and electroplating ABS can be replaced; adhesive force between an electroplating polypropylene plastic part and a coating is improved, the weight of a workpiece is reduced, and heat resistance of the electroplating polypropylene alloy material is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an electroplated polypropylene alloy material and a preparation method thereof. Background technique [0002] With the rapid development of industry, the application of plastic electroplating has become one of the important means of surface decoration in plastic products. Compared with metal parts, plastic electroplating products can not only achieve a good metal texture, but also reduce the weight of the product. While effectively improving the appearance and decoration of the plastic, it also improves its electrical, thermal and corrosion resistance. Performance, improve its surface mechanical strength. However, the selection of plastic materials for electroplating should comprehensively consider factors such as the processing performance of the material, the difficulty of electroplating, and the dimensional accuracy. [0003] At present, the plastic products that c...

Problems solved by technology

[0003] At present, the plastic products that can be used for electroplating can only choose ABS materials, but due to their structural characteristics, they cannot meet the mechanical properties such as impact strength, tensile strength, and flexural modulus at the same time; and the cost of ABS materials has always been high.

Polypropylene (PP) is a semi-crystalline thermoplastic, which is cheap, can also meet the requirements of strength and mechanical properties, and is resistant to various organic solvents and acid and alkali corrosion, but because of its high crystallinity, It is difficult to roughen the surface, and the adhesion of the coating is poor, so it is difficult to obtain application in parts that require electroplating
