Waterborne wood paint and preparation method thereof

Abstract

Undercoat comprises the following components by weight: 50-80% of emulsion, 0.1-0.5% of a wetting agent, 0.1-0.5% of a defoamer, 0.5-2% of waterborne zinc stearate, 2-8% of a coalescing agent, 1-5% oftalcum powder, 0.1-0.5% of a thickener, and 10-30% of deionized water; finishing coat comprises the following components by weight: 50-80% of emulsion, 0.1-0.5% of a wetting agent, 0.1-0.5% of a defoamer, 1 to 5% of waterborne wax, 2-8% of a coalescing agent, 1-5% of sub-fine powder, 0.1-0.5% of a thickener, and 10-30% of deionized water. The modified styrene-acrylic emulsion is used to successfully develop the waterborne wood paint, the preparation method of the wood paint is simple, the cost of the wood paint is low, and the performance meets the requirements of the relevant national standard on the wood paint.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to a water-based wood paint and a preparation method thereof. Background technique [0002] Water-based wood paint is more and more popular in the market due to its advantages of environmental protection, non-toxic, odorless, very little volatile matter, high safety of non-flammable and non-explosive, non-yellowing, and large painting area. However, there are still many problems in water-based wood paint. For example, poor physical and chemical properties of the coating film, easy cracking, wrinkling, whitening, poor adhesion, and high price are the main problems of water-based wood coatings. [0003] In order to solve the above problems, the present invention adopts modified styrene-acrylic emulsion, and adds appropriate amount of water-based zinc stearate, water-based wax, etc. to modify it during the paint mixing process, so as to obtain low-cost and good-performance wood va...
