Low-smell platable polypropylene material and preparation method thereof

Abstract

The invention discloses a low-smell platable polypropylene material. The low-smell platable polypropylene material comprises the following components in parts by weight: 650-720 parts of PP, 20-40 parts of CPP, 10-50 parts of a compatilizer, 200-300 parts of an inorganic filling material, 3-5 parts of a composite smell inhibitor, 4-8 parts of a composite anti-oxidant, 4-6 parts of a lubricant, 2-3 parts of a bridging agent, and 5-8 parts of conductive graphite. Through the addition of the composite smell inhibitor, the smell grade of the continuous glass fiber reinforced polypropylene composite material can reach more than 3, in addition, the polypropylene material has good electroplating performance, electroplating can be carried out according to an ABS electroplating technology, the adhesive force between a product after injection moulding with the material of the invention and a coating layer is strong, the surface gloss is high, the material cost is low, and the product after injection moulding can be recovered and used after being crushed.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-odor electroplatable polypropylene material and a preparation method thereof. Background technique [0002] With the rapid development of industry, the application of plastic electroplating is becoming more and more extensive, and it 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. ...

AI Technical Summary

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 performance requirements 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 meet the requirements of strength and mechanical properties, and is resistant to various organic solvents and acid-base corrosion, but because of its high crystallinity, the surface Roughening is more difficult, and the adhesion of the coating is poor, so it is difficult to obtain application in parts that require electroplating
