Abstract

The invention discloses ultraviolet curing transparent color-repairing mother liquid as well as a preparation method and application thereof. The ultraviolet curing transparent color-repairing motherliquid comprises the following raw materials: 27 to 63 parts of polyurethane acrylate oligomer, 10 to 45.5 parts of epoxy acrylate oligomer, 2 to 5 parts of epoxy resin, 10 to 20 parts of active monomer, 2 to 10 parts of bridging agent, 0.01 to 1.5 parts of ultraviolet absorber, 1 to 3.5 parts of free radical photoinitiator, 1.5 to 3.5 parts of cationic photoinitiator, 0.1 to 0.3 part of defoamingagent, 0.5 to 1.0 part of leveling agent and 0.8 to 1.5 parts of wetting agent. The ultraviolet curing transparent color-repairing mother liquid is prepared from the acrylate oligomer containing an unsaturated double bond, the epoxy resin and the active monomer which serve as main film-forming substances as well as the photoinitiator and various other aids through dispersing and stirring; and theprepared color-repairing mother liquid has the advantages of high storage stability, excellent curing property and no influence on adhesive force when 25 percent of color concentrate can be added atmost for one time.

Description

technical field [0001] The invention relates to a color-correcting auxiliary material for coatings, in particular to a UV-curable transparent color-correcting mother liquor and a preparation method and application thereof. Background technique [0002] In the process of furniture making, in order to make it appear more beautiful and more diverse colors, it is often necessary to color the paint and combine different painting construction techniques to make the furniture into a design effect. Among them, the color can be divided into transparent color and solid color. After painting, only the color of the board surface is changed, but the texture of the substrate can still be seen. Only the color of the paint itself is displayed, and the furniture painted in solid color is often pure white, pure black, pure blue, etc. [0003] Transparent color furniture samples are often made of base coloring, surface coloring or base coloring and surface coloring. The base coloring is appl...
