Problems solved by technology

[0003] Water-based matte clear topcoats are widely used in wood coatings, but when water-based matte clear topcoats are applied to large-scale furniture coatings, the following problems often occur: some have good transparency but poor gloss; Requirements but poor transparency, can not show the beauty of wood; and there is also poor storage stability, a period of time due to the precipitation of matte powder resulting in unstable luster

preparation example Construction

[0033] On the other hand, the present invention also provides a preparation method of a high-resistance, anti-yellowing special clear matte varnish, which comprises the following steps:

[0034] Step 1, add water-based acrylic resin, matte water-based acrylic resin and deionized water into the reactor and mix well;

[0035] Step 2, add defoamer at a speed of 500-600r / min, and disperse for 10-20min at a speed of 1000-1200r / min;

[0036] Step 3, pre-mix the film-forming aid, pH regulator and deionized water evenly and add them to the reaction kettle, disperse at 1000-1200r / min for 10-20min, until the fineness is ≤20μm, pH8-9 And no shrinkage cavity;

[0037] Step 4: Add a wetting and leveling agent into the reaction kettle, disperse for 15-20min at a speed of 600-800r / min; then add a thickener, and stir for 10-20min at a speed of 800-1000r / min, until the viscosity 65-75s.

[0038] Alcohol resistance described in the present invention is to test 1H in 50% ethanol solution.

Abstract

The invention provides ultra-clear matt finish paint with high resistance and yellowing resistance. The finish paint is prepared from 50-60 parts by mass of aqueous acrylic resin and 20-25 parts by mass of matt aqueous acrylic resin, wherein the aqueous acrylic resin and the matt aqueous acrylic resin are mixed in a ratio being (2-3) / 1. The ultra-clear matt finish paint with high resistance and yellowing resistance has the advantages of good resistance, good yellowing resistance, good transparency and good stability.

Description

technical field [0001] The present invention relates generally to the field of coatings, and in particular, to high-durability, anti-yellowing ultra-clear matte clear topcoats and methods for their preparation. Background technique [0002] With people's increasing requirements for environmental protection and health, as well as the continuous improvement and strengthening of domestic and foreign environmental protection laws and regulations, water-based wood coatings have attracted more and more attention. [0003] Water-based matte clear topcoats are widely used in wood coatings, but when water-based matte clear topcoats are applied to large-scale furniture coatings, the following problems often occur: some have good transparency but poor gloss; It is required but the transparency is poor, and the beauty of wood cannot be displayed; and there is also poor storage stability, and the matte powder precipitates over a period of time, resulting in unstable luster. [0004] The...
