Abstract

The invention discloses a polypropylene composite material suitable for electroplating reaction. The polypropylene composite material suitable for electroplating reaction comprises, by weight, 35 to 75% of polypropylene, 20 to 45% of an inorganic filling material composition, 0.5 to 1% of a grafting monomer composite material, 0.3 to 0.5% of an initiator, 0.2 to 0.8% of an anti-oxidant, 0.1 to 0.5% of a lubricant, and 0.3 to 1% of a polymer type surfactant. The invention also discloses a preparation method of the polypropylene composite material. The polypropylene composite material possessesexcellent hydrophilic performance, is convenient for electroplating pretreatment; the plating layer glossiness and clunging force of products obtained via electroplating are excellent.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene composite material suitable for electroplating reaction and a preparation method thereof. Background technique [0002] Plastic electroplating is an important means to improve the surface properties of plastic parts, prolong the service life and expand the scope of use. After electroplating, the surface of plastic has a metallic luster, which improves heat resistance, wear resistance, thermal stability and corrosion resistance. Polypropylene is one of the five general-purpose plastics, and there are many types of modified polypropylene, which are widely used. Polypropylene has the characteristics of high crystallinity and low polarity. Although it can be electroplated under a specific process, the process is complicated and the electroplating cycle is long, which greatly limits its application in electroplating. [0003] At present, the plas...
