Abstract

The invention discloses a self-cleaning water-based woodware finish paint and a preparation method thereof. The self-cleaning water-based woodware finish paint comprises the following raw material components in parts by weight: 45-60 parts of water-dispersed polyurethane resin or water-dispersed alkyd resin, 15-25 parts of water-based silica sol, 10-25 parts of functional powder, 2.4-6.5 parts of a functional additive and 0.5-1.5 parts of water, wherein the functional powder comprises the following raw materials in parts by weight: 25-50 parts of nanometer talcum powder, 25-50 parts of nanometer calcium carbonate and 25-50 parts of nanometer kaolin. According to the water-based woodware finish paint, the property that the stability of the water-based silica sol is high is utilized, nanoscale aperture and a continuous three-dimensional network structure are adopted, and a nanometer filling material is added, so that the finally formed film has lower surface energy, the water-based woodware finish paint which can be dried in air and is lower in cost, healthy and safe, is prepared, the defect that the coating can easily shrink when being dried is overcome, and the coating can achieve the characteristics of being self-cleaning, antifouling, hydrophobic, oleophobic and the like.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a self-cleaning water-based wood topcoat and a preparation method thereof. Background technique

[0002] Due to its excellent environmental protection characteristics, water-based wood paint greatly reduces the emission of organic solvents to the atmosphere, avoids environmental pollution and physical hazards to construction workers, and has the advantages of convenient use and simple construction. With the continuous improvement of environmental protection requirements in various countries around the world , water-based wood coatings have also begun to replace traditional organic solvent-based coatings and have been widely used. At present, the biggest problems of water-based coatings are the disadvantages of poor water resistance, slow drying speed of the coating film, and low hardness.

[0003] Because the self-cleaning surface has many unique surface properties: such as ant...
