Abstract

The invention discloses a ceramic coating sprayed on an SMC plate. The ceramic coating comprises a primer paint, scatter paint and finish paint, which are sequentially coat the SMC plate. The primer paint is prepared from the following raw materials by weight: 25-40 parts of ceramic resin, 5-10 parts of metal oxide solution, 1-10 parts of a coloring pigment, 0.5-2 parts of an orientation additive,4-7 parts of a dispersing agent, 2-4 parts of modified polylactic acid and 12-20 parts of water. The scatter paint is prepared from the following raw materials in parts by weight: 15-30 parts of ceramic resin, 5-15 parts of a metal oxide solution, 1-10 parts of coloring pigment, 10-15 parts of basic filler, 1-5 parts of thermal insulation filler, 0.5-2 parts of orientation additive, 2-5 parts ofa scatter additive, 2-6 parts of polylactic acid, 0.5-2 parts of polyhydroxybutyrate and 12-20 parts of water. The finish paint is prepared from the following raw materials in parts by weight: 20-30 parts of ceramic resin, 5-10 parts of polybutadiene latex, 2-5 parts of 3-propylene glycol, 1-3 parts of polyethylene glycol, 4-7 parts of a dispersing agent and 12-20 parts of water. The ceramic coating has a three-layer structure and is high in decoration property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a ceramic coating sprayed on an SMC board and a preparation method thereof. Background technique [0002] SMC is a new type of thermosetting FRP molding material, which is made of unsaturated polyester resin paste impregnated with chopped fiber roving with thickener, low shrinkage additive, filler, release agent and colorant. A sheet of film plastic. SMC materials have excellent electrical insulation properties, mechanical properties, thermal stability, and chemical corrosion resistance, so SMC products have a wide range of applications. In specific use, they need to be sprayed with paint for decoration. At present, conventional paints are used to spray SMC boards. There are the following disadvantages: First, the bonding ability between ordinary paint and SMC board is poor; second, ordinary paint is a single coating, once the coating cracks, the water and corrosive substances ...
