Problems solved by technology

Matting powder or diatomaceous earth and other powders with matting effect are evenly dispersed in the paint film after being applied to the emulsion system, forming a layer of uneven rough surface on the surface, increasing light scattering to reduce the gloss of the paint film, but This method can easily lead to poor storage stability of the product, easy delamination, poor appearance, poor transparency, poor water whitening resistance when applied to exterior walls, etc.

Embodiment

[0040] The three kinds of matte clear finish paints in this embodiment include the raw material components shown in Table 1 by weight percentage.

[0041] Table 1

[0042]

[0043] The preparation method of the above-mentioned modified hydroxyethyl cellulose aqueous solution is as follows: add water to the modified hydroxyethyl cellulose according to the stated mass concentration, disperse at a low speed for 20 minutes to prepare a pregel solution, and leave it overnight.

[0044] The preparation method of above-mentioned matte cover clear finish paint, comprises the steps:

[0045] Mix and stir the water and thickener for 5 minutes, add dispersant, wetting agent, defoamer, and film-forming aid in sequence, and mix and stir for 10 minutes; then add the core-shell structure acrylic copolymer emulsion and mix for 5 minutes, and finally mix the wax Emulsion, preservative, antifungal agent, antifreeze, pH regulator and rheological additive are added in sequence, and stirred fo...

Abstract

The invention relates to matte finishing clear coat and a preparation method thereof. The matte finishing clear coat is made from the following materials according to percent by weight: 25-65% of core-shell acrylic copolymer emulsion, 0.05-6% of a thickener, 0.1-5% of a rheological aid, 0.1-0.6% of a dispersant, 0.1-0.6% of a wetting agent, 1.5-2% of a film-forming aid, 0.5-5% of a wax emulsion, 0.1-0.5% of a defoaming agent, 1.5-7.0% of a functional aid, and 20-65% of water. The matte finishing clear coat is still good in matte effect even no matting agent is added, storage stability of a system is good, a coat film has good transparency and water white resistance, and the matte finishing clear coat has excellent comprehensive performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a matte clear finish paint and a preparation method thereof. Background technique [0002] In recent years, as people pay more attention to the decorative effect of the wall, not only the functionality of the wall paint is required, but also the good appearance and decorative effect of the wall are required. The varnish topcoat can not only increase the protection of the paint coating for external use, improve performance requirements such as durability, stain resistance, and temperature change resistance, but also increase the protection and decorative effect of the interior paint. [0003] At present, the clear finish paint used for interior and exterior walls is mainly bright, and the effect after construction is high gloss and dazzling. After being applied to exterior walls, it is easy to be polluted by dust, impurities and other pollutants in the air, losing the decorative effect, an...
