Problems solved by technology

However, in the prior art, due to its high water content and insufficient viscosity, the paint dries slowly during the actual painting process, because many steps in the decoration process need to be carried out after painting. , so the drying speed of the paint directly affects the progress of the decoration, and in the later period, the paint will fall off the wall. When the paint is repainted on the wall, if the drying speed of the paint is slow, it will affect the normal life.

preparation example Construction

[0019] The present invention also provides a coating preparation method, wherein the method includes mixing the main resin, organic bentonite, filler, solvent, defoaming agent, leveling agent and drier and mixing them uniformly; the amount of each substance is such that The content of the main resin in the prepared coating is 40-75% by weight, the content of the organic bentonite is 0.5-2% by weight, the content of the filler is 10-30% by weight, and the content of the solvent is 10-30% by weight, the content of the defoamer is 0.05-0.2% by weight, the content of the leveling agent is 0.05-0.2% by weight, and the weight of the drier is 0.1-0.6% by weight.

[0020] In the above coatings, in order to make the prepared coatings have better physical properties and achieve better quick-drying effects, preferably, the amount of each substance is such that the content of the main resin in the prepared coating is 55- 65% by weight, the content of the organic bentonite is 0.8-1.3% by weig...

Embodiment 1

[0032] Combine 55 parts by weight of short oil alkyd resin, 1.3 parts by weight of organic bentonite (the organic bentonite contains 0.12 parts by weight of bentonite, 1.15 parts by weight of ethyl acetate and 0.03 parts by weight of 95% ethanol) and 25 parts by weight Mix and stir evenly the butyl acetate of, to obtain a mixture M1; add 18 parts by weight of talc, 0.08 parts by weight of calcium oxide defoamer, 0.08 parts by weight of polyether modified polydimethylsiloxane and 0.54 parts by weight Add the dibutyltin dilaurate to the mixture M1, mix and stir evenly.

Embodiment 2

[0034] Combine 65 parts by weight of short oil alkyd resin, 0.8 parts by weight of organic bentonite (the organic bentonite contains 0.08 parts by weight of bentonite, 0.7 parts by weight of ethyl acetate and 0.02 parts by weight of 95% ethanol) and 16 parts by weight Mix and stir evenly to obtain a mixture M1; 17.5 parts by weight of talc, 0.1 parts by weight of calcium oxide defoaming agent, 0.1 parts by weight of polyether modified polydimethylsiloxane and 0.5 parts by weight Add the dibutyltin dilaurate to the mixture M1, mix and stir evenly.

Abstract

The invention discloses a coating and a preparation method thereof. Based on the total weight of the coating, the coating comprises the following components: 40-75wt% of matrix resin, 0.5-2wt% of organic bentonite, 10-30wt% of filler, 10-30wt% of solvent, 0.05-0.2wt% of defoaming agent, 0.05-0.2wt% of flatting agent and 0.1-0.6wt% of drier. Organic bentonite is added into resin, so that the viscosity of the coating is greatly increased; the solvent is added, so that the viscosity of the produced coating is kept relatively high; the drier is also added into the coating, so that the coating drying speed is increased, and furthermore, the effects of rapidly drying the coating and increasing the working efficiency can be achieved.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a coating and a preparation method thereof. Background technique [0002] With the increasing development of life, the construction industry has also developed by leaps and bounds. As an indispensable material in the construction industry, coatings have been extremely widely used in the construction industry. It can be said that there is almost no construction in daily construction. No paint is needed. However, in the prior art, the paint dries slowly in the actual painting process due to its high water content and insufficient viscosity, because many steps in the decoration process need to be continued after painting Therefore, the drying speed of the paint directly affects the progress of the decoration, and the phenomenon of paint falling on the wall in the later period, when the wall is repainted, if the drying speed of the paint is slow, it will affect normal life. [0003] Ther...
