Water-based quick drying painting and preparation method thereof

A fast-drying coating and water-based technology, applied in the field of coatings, can solve the problems of affecting the color of decorative coatings, affecting the appearance quality of coatings, and hindering the diffusion of water vapor, so as to shorten the curing cycle of coatings and reduce the migration and drying of moisture to the outside. Process, the effect of improving hardness and wear resistance

Problems solved by technology

[0002] With the improvement of environmental protection requirements, more and more products or environmental occasions choose to use water-based coatings. On the one hand, it can reduce environmental pollution and on the other hand, it can reduce production costs. The air permeability of the paint is relatively poor, and the poor air permeability of the paint will hinder the diffusion of water vapor, affect the color of the finishing paint, generate stress, cause the paint to bubble and fall off, and the interior contains a lot of water. During the drying process, in order to To form a dry film coating, it needs to wait for a long time for the internal moisture to migrate out, which prolongs the construction or product production cycle. Sometimes in order to facilitate the drying of the paint, multiple coatings may be performed, and the thickness of each coating can be selected. The order of magnitude is small, and during the drying process of the paint, the surface of the paint layer will also be irregularly sunken due to internal water loss, which greatly affects the appearance quality of the paint

Embodiment 1-2

[0024] A preparation method for water-based quick-drying paint, comprising the steps of:

[0025] 1), prepare the pigment (color paste) by water-based resin and pigment in proportion;

[0026] 2) Mix resin, color paste, filler, defoamer, leveling agent, wetting agent and water in proportion and stir evenly;

[0027] 3) Before the coating operation, add the anti-corrosion quick-drying inorganic film-forming agent (sodium dihydrogen phosphate mixed with phosphogypsum powder) and the dispersant into the resulting mixture and stir rapidly for 10 minutes to obtain the water-based quick-drying coating.

Embodiment 3-4

[0029] A preparation method for water-based quick-drying paint, comprising the steps of:

[0030] 1), prepare the pigment (color paste) by water-based resin and pigment in proportion;

[0031] 2) Mix resin, color paste, filler, defoamer, leveling agent, wetting agent and water in proportion and stir evenly;

[0032] 3) Before the coating operation, add the anti-corrosion and quick-drying inorganic film-forming agent (phosphate system, such as Zhongshan Kebang's phosphate, grade 9800) and dispersant to the resulting mixture and stir quickly for 15 minutes to obtain a water-based quick-drying coating .

Abstract

The invention discloses a water-based quick drying painting and a preparation method thereof. The key point of the technical scheme is that the water-based quick drying painting comprises the following components in parts by weight: 45-60 parts of water-based resin, 6-15 parts of filler, 3 parts of pigment, 8-13 parts of auxiliaries, 5-20 parts of antiseptic quick drying inorganic film-forming agent and 5-20 parts of water. The water-based quick drying painting disclosed by the invention is capable of increasing the setting rate of water-based painting, meets the quick coating requirement forthick coatings and is capable of improving the poor coating appearance.
