Abstract

The invention discloses an odor-removing transparent color paste which is prepared from the following raw materials in percentage by weight: 40-45% of TDI modified linseed alkyd resin, 6-9% of anti-settling resin, 7-9% of hydroxyl castor oil alkyd resin, 7-9% of dispersing agent, 0.8-1% of anti-skinning agent, 1-3% of dryer, 18-22% of transparent pigment and the rest of d80 solvent oil. Accordingto the odor-removing transparent color paste disclosed by the invention, different kinds of resin are dried so as to effectively avoid the risk of collapse of the product wiping a color strip on a solid-wood white body.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an odor-free transparent color paste and a preparation method thereof. Background technique [0002] The color paste is a mixed paste obtained by adding fillers and some additives to the pigment. The color paste is dispersed in the paint to form a colored paint. Among them, the color paste with pure oil as adhesive is called oily color paste; the color paste with resin paint as adhesive is called resin color paste; the color paste with water as medium is called water-based color paste; [0003] The existing products for rubbing color on solid wood furniture are mainly Grace color paste products, which have the characteristics of uneven color rubbing and not deep coloring of white blanks, so it is often necessary to spray or brush one coat on white blanks during construction. Close the bottom and then rub the color. Because the depth of coloring is not enough, and it cannot p...
