Problems solved by technology

[0003] BMC materials on the market usually add glass fiber (such as 201110154989.8, 201110155003.9, 201110155005.8). However, the addition of glass fiber will make the surface of the product prone to fiber marks and affect the appearance. The post-processing cutting tool wears quickly, and the dust is relatively large during the cutting process. Large and fine fiber scraps will invade the human skin, causing discomfort, and there will be quality problems such as blackening and intolerance to pollution after the corners are polished

Abstract

The invention relates to a bulk molding compound composite material, which is prepared from the following components in parts by weight: 70-90 parts of unsaturated polyester resin, 10-30 parts of low shrinkage additive, 2-10 parts of polyvinyl alcohol fiber, 60-240 parts of filler, 0.8-2 parts of thickener, 1-2 parts of initiator, 3-6 parts of internal releasing agent, 0.1-5 parts of pigment, and 5-20 parts of color chips, wherein the unsaturated polyester resin is orthophthalic unsaturated resin or M-unsaturated resin. A glass fiber is replaced by a polyvinyl alcohol fiber, so that the tenacity of the product is greatly improved when the rigidity of the product meets the requirements. The bulk molding compound composite material has good anti-fouling performance, a tool is not easily abraded in the cutting and polishing processes, and the bulk molding compound composite material is less in dust in the polishing process, good in anti-fouling performance after being polished, and beneficial to industrial production.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a bulk molding compound composite material and a preparation method thereof. Background technique [0002] With the development of the modern construction industry, requirements for light weight, high strength and beautiful appearance are put forward for building materials. Artificial marble appears under this trend. Artificial marble has good physical and chemical properties and is suitable for various purposes. It is now the construction industry. The main decoration material in the decoration market. At present, the countertops of cabinets and bathroom cabinets made of BMC (bulk molding compound) materials have appeared on the market. They are not only high in strength but also light in weight, and the surface of BMC materials is dense, non-porous, non-absorbent, and easy to clean. And acids, oils, tea, coffee, soft drinks, etc. will not leave marks o...
