Aqueous semitransparent pigment type colorant used for carpentry paint and preparation method thereof

Abstract

The invention discloses an aqueous semitransparent pigment type colorant used for carpentry paint and a preparation method thereof. The aqueous semitransparent pigment type colorant contains the following materials by weight percent: 20-40% of aqueous linseed oil, 20-40% of anba powder or transparent ferric oxide pigment and organic pigment, i.e. permanent yellow, rose Bengal and black pigment, 2-5% of aerosil, 1-3% of aqueous dispersant, 10-20% of propanediol and 10-20% of water. The preparation method of the aqueous semitransparent pigment type colorant comprises the following steps: (1) adding the aqueous linseed oil into a container; (2) then, adding the propanediol and the water into the container; (3) then, adding the aqueous dispersant into the container, and uniformly stirring and mixing the materials; (4) finally, adding the aerosil, the anba powder or the transparent ferric oxide pigment into the container; (5) uniformly stirring the materials, and then grinding the materials into 15 UM to be qualified by a grinder so as to be used. The invention can be used for the wiping and coating process of pseudo-classic furniture or American furniture.

Description

technical field [0001] The invention relates to a water-based colorant in wood furniture paint and a production method thereof, in particular to a colorant in antique furniture wiping coating or American furniture wiping coating and a production method thereof. Background technique [0002] The colorants in wood furniture paint are mainly divided into two types: pigments and dyes. Pigments are colorants that are insoluble in common solvents, so in order to obtain ideal coloring performance, it is necessary to uniformly disperse the pigments in the base material by mechanical means. Pigments can be divided into organic pigments and inorganic pigments according to their structure. Inorganic pigments have excellent thermal stability and light stability, high relative density, low price, but relatively poor tinting power; organic pigments have high tinting power, low relative density, bright color, complete chromatogram, and the disadvantages are heat resistance, weather resist...

Problems solved by technology

The first defect of this colorant is that the solvent in it is harmful to the human body, it will cause harm to the personnel who paint the construction, and pollute the environment; the second defect is that the colorant will precipitate when it is stored for a long time Or thicken, affecting the quality of the coating; the third defect is that the colorant is difficult to show the wood grain on the furniture
