Embodiment
[0030] A polypropylene composite material suitable for electroplating reactions comprising, by weight percent:
[0031]
[0032]
[0033] The polypropylene in this example is homopolypropylene, and its melt index at a temperature of 230°C and a test load of 2.16kg is 2-4g / 10min; the inorganic filler composition is calcium carbonate and calcium carbonate with a particle size of 3-10 microns. Two mixtures of barium sulfate; the mixing ratio is calcium carbonate: barium sulfate = 2:1 by mass ratio. The grafted monomer compound is a compound system of two unsaturated carboxylic acids, and two monomers of glycidyl methacrylate and acrylic acid are used for compounding, wherein glycidyl methacrylate and acrylic acid are grafted The weight ratio of the monomers is 1.5:1 to 2:1 respectively.
[0034] The initiator in the present embodiment is benzoyl peroxide; Antioxidant includes main antioxidant and auxiliary antioxidant, main antioxidant and auxiliary antioxidant are mixed b...
