Problems solved by technology

[0004] The traditional overmold coating must be baked or sprayed after the molding compound has been thermally processed, which requires a separate paint production line, which must be cleaned before painting, and then undergoes painting and curing procedures; the paint production line requires a large investment in equipment and more manpower High investment, high power consumption, and easy release of organic gases that are harmful to the environment. The final product's baking paint layer has poor scratch resistance and frequent friction performance

Abstract

The invention provides a PIMC (Powder in Mould Coating) coating for BMC (Bulk Molding Compounds) / SMC (Sheet Molding Compounds) with the effect of brilliant silver metal. A formula of the PIMC coating is prepared from the following components including resin, a curing agent, a flow agent, titanium dioxide powder, a pigment / filler, other adjuvants and silver powder. The PIMC coating is prepared by the following steps of raw material weighing, premixing, melt extrusion, crushing, sieving, packaging and finished production preparation. A coating method of the powder coating comprises the following steps of using electrostatic spraying equipment to carry out spraying, spraying the powder coating on a heated die, and then adding SMC / BMC to carry out press forming.

Description

technical field [0001] The invention belongs to the field of chemical materials, and in particular relates to a PIMC coating for BMC / SMC with flashing silver metal effect and a preparation method thereof. Background technique [0002] PIMC is the English abbreviation of Powder in Mold Coating, which means in-mold coating. PIMC can not only make the outer surface of the product compact and beautify, but also be used as a primer / primer. BMC is the abbreviation of Bulk Molding Compounds, that is, bulk molding compound, also known as unsaturated polyester bulk molding compound, and SMC is the abbreviation of Sheet Molding Compounds, that is, sheet molding compound. These two materials have excellent electrical properties , mechanical properties, heat resistance and chemical corrosion resistance, and adapt to various molding processes, widely used in automobile production, railway transportation, construction accessories, mechanical and electrical products and other fields.
