Novel solid-color multi-coating composition layer

Abstract

The invention relates to a novel solid-color multi-coating composition layer which is characterized by sequentially comprising a UV (ultraviolet) bottom layer, a solid-color coating layer and a UV upper surface layer, wherein the primary pulp of the UV bottom layer is formed by adding mineral powder into UV coating primary pulp for uniform stirring; the solid-color coating layer is formed by adding alkyd resin with an adhesion infiltration effect into a solid-color coating. According to the novel solid-color multi-coating composition layer, the characteristic that another coating layer cannot be adhered to the surface of the UV coating primary pulp due to the fact that the molecular density of the UV coating primary pulp is increased (namely gaps between molecules are gradually reduced) in a drying process of the UV coating primary pulp is actually utilized, a physical principle is utilized, the mineral powder is added into the UV coating primary pulp, and the mineral ions of the mineral powder enter the molecular gaps of the UV coating primary pulp, so that the molecular density of the surface of the UV coating primary pulp is lower than that of a UV coating in the prior art after the UV coating primary pulp is dried, and the solid-color coating layer can be conveniently and smoothly arranged on the upper surface of the UV bottom layer.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a novel composite layer of multi-coating solid-color coatings. Background technique [0002] Traditional coatings are generally composed of grease, pigments, and fluxes. However, traditional coatings have been proven to pollute the environment and endanger human health. At the same time, with the advancement of science and technology, a new type of coating has gradually entered the coating market, that is, ultraviolet light. Curing coating (UV), which is an environmentally friendly and energy-saving coating characterized by the use of radiation curing technology. Compared with traditional coatings, UV coatings have some excellent properties such as energy saving, pollution-free, high efficiency, and suitable for heat-sensitive substrates. However, this new type of coating still has some defects (it cannot be used as a full-covering solid color), that is, when the UV coating is applied to ...

[0002] Traditional coatings are generally composed of grease, pigments, and fluxes. However, traditional coatings have been proven to pollute the environment and endanger human health. At the same time, with the advancement of science and technology, a new type of coating has gradually entered the coating market, that is, ultraviolet light. Curing coating (UV), which is an environmentally friendly and energy-saving coating characterized by the use of radiation curing technology. Compared with traditional coatings, UV coatings have some excellent properties such as energy saving, pollution-free, high efficiency, and suitable for heat-sensitive substrates. However, this new type of coating still has some defects (it cannot be used as a full-covering solid color), that is, when the UV coating is applied to the surface of the object to be coated, due to drying, the molecular density in the UV coating becomes smaller, and it cannot be used in other areas. The surface is covered with nitro-based solid-color paint, so when making a solid-color multi-coat combination layer, UV paint will not be used as the bottom layer, and when the traditional surface is treated with solid color, it is more common to use baking varnish. way, but in this way, it is prone to surface foaming, which has pollution
