Problems solved by technology

[0008]1. Use patterned or printed water-based paper or base paper as the raw material for veneer materials. Although it can produce finished products with various patterns on the surface, or achieve real wood grain And the effect of stone, but the surface of the product is easy to be damp and moldy; due to the low strength and toughness of the paper, cracks will appear on the surface of the product after long-term use, which seriously affects the apparent quality of the product;
[0009]2. The matrix resin of the veneer material is unsaturated polyester resin such as bisphenol A type unsaturated resin, the corrosion resistance of the veneer layer formed after curing The toughness and toughness cannot meet the application requirements of the product in the sanitary field, the surface layer is easily corroded, and the surface quality of the product cannot be maintained for a long time;

Abstract

The invention discloses glassfibre reinforced plastics and a preparation method thereof. The reinforced plastics comprises a structural layer and a surface layer, wherein the structural layer is made of a resin base material and glassfibres dispersed in the resin base material, and the surface layer is attached on the surface of the structural layer and is made of a surface lining material; the surface lining material is formed by uniformly coating resin paste on a facing material, and then precuring and drying; and the resin paste is formed by mixing the following components in parts by weight: 100 parts of vinyl resin, 1-2 parts of initiator, 2-4 parts of inner mold release agent, 30-130 parts of inorganic fillings, 20-90 parts of wear resistant powder, 15-50 parts of vinyl benzene, 0.5-2 parts of coupling agent and 1-20 parts of low shrink additive, wherein the wear resistant powder has the grain size of 10-74mum and the hardness of 8-10Mohs, and the facing material is a non-woven fabric of 60-100g / cm<2>. The reinforced plastics has favorable surface quality after being stored for a long term and is particularly suitable for application occasions with severer environments in the fields of bathrooms and the like.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic and a preparation method thereof. Background technique [0002] Glass fiber reinforced plastics, commonly known as glass fiber reinforced plastics, are made by adding fibrous reinforcement materials to thermosetting resin substrates, and are usually manufactured by compression molding. Compression molding includes lamination molding, compression molding, hand lay-up molding and other methods. At present, the rapid development is the block or bulk molding compound molding process (BMC, DMC) and sheet molding compound molding process ( SMC). [0003] In reinforced plastics, unsaturated resins and m-phenylene resins are the most commonly used resin substrates, in which glass fibers, inorganic fillers, and metal oxides such as magnesium oxide are added as reinforcing materials. According to the different characteristics of the product, the amount of glass fiber added usually fluctuates between 20%...
