Abstract

The invention discloses a matte repairable BMC material and a preparation method thereof. The matte repairable BMC material comprises the following raw materials in percentage by weight: 15%-25% of unsaturated polyester resin, 5%-10% of an additive, 50%-60% of filler, 10%-20% of glass fiber, 1%-2% of an initiator, 1%-2% of an internal release agent, 1%-2% of a thickening agent, 0.5%-1% of a coloring agent and 1%-2% of a dispersing agent. According to the invention, previous ingredients are re-proportioned, a new kneading technology is applied, and then high-temperature mould pressing is carried out, so that the product has specific glass fiber lines and more uniform particle distribution, and more importantly, the product has unique characteristics and is polishable and repairable, and a sanitary appliance product produced by the reformed technology is fine, smooth, clean and moist in surface, good in durability, good in durability, elegant in shape, comfortable in body feeling, high in strength and durable in service.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a matte repairable BMC material and a preparation method thereof. Background technique [0002] Existing sanitary ware, building materials and wall panels are of a great variety, such as metal products, ceramic products, glass products, and composite products. Especially in the field of composite materials, the production process includes pouring, RTM, acrylic blister and molded composite products, but because the molded sanitary ware products are not repairable or the surface is polished, the final pass rate of the product is reduced due to surface defects. It is often difficult to apply the molding technology to the production technology of civil sanitary ware products and change it to industrial intermediate products. Therefore, need provide a kind of new technical scheme and give solution. Contents of the invention [0003] The object of the present invention is to ...
