Embodiment 1

[0041] A preparation method of water-based paint for magnesite handicrafts, the method may further comprise the steps:

[0042] (1) According to the formula requirements, 40 kg of modified acrylate emulsion 1 (glass transition temperature is 20-22°C) and 35 kg of modified acrylate emulsion 2 (glass transition temperature is 50-52°C) are put into the dispersion Tank, start stirring, under the speed of 300-500r / min, put in 4 kg of propylene glycol butyl ether, 2 kg of dipropylene glycol propyl ether, 0.2 kg of defoamer, 0.5 kg of surfactant, 18 kg of deionized water, thickener 1.0 kg, 0.1 kg preservative, keep stirring for 15-30 minutes;

[0043] (2) Regulate the viscosity of the solution obtained in step (1) with deionized water, so that the time for the solution obtained in step (1) to flow through the ISO6# outflow cup is 30~50s;

[0044] (3) Weigh and pack to obtain the water-based paint for magnesite handicrafts.

Embodiment 2

[0046] A preparation method of water-based paint for magnesite handicrafts, the method may further comprise the steps:

Abstract

The invention relates to a water-based paint for magnesite handicrafts and a preparation method thereof. The water-based paint is made of the following components and raw materials in parts by weight: 70-80 parts of water-based emulsion, 5-7 parts of film-forming aids, and 0.2 parts of defoaming agent ~0.4, preservative 0.1~0.3, thickener 1.0~1.5, surfactant 0.5~1.0, deionized water 12~20; the preparation method is: put the water-based emulsion into the dispersion tank, start stirring, at a speed of 300~500r / Add film-forming aids, defoamers, surfactants, deionized water, thickeners and preservatives in sequence, and keep stirring for 15-30 minutes; adjust the viscosity of the obtained solution with deionized water, and let the obtained solution flow through The time for ISO 6# to flow out of the cup is 30-50s; weigh and pack. Compared with the prior art, the water-based paint for magnesite handicrafts prepared by the present invention has good adhesion, the drying time of the water-based paint is short, the anti-blocking property and stain resistance are good, and the total volatile organic compound content of the water-based paint less, good for the environment.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a water-based coating for magnesite handicrafts and a preparation method thereof. Background technique [0002] Magnesite handicrafts use concrete materials and molded sculpture techniques to produce sculptures that imitate stone, imitation wood, imitation porcelain, and imitation metal. They have simple process, high strength, light weight, no deformation, cold resistance, aging resistance, and waterproof , Fireproof, mothproof, corrosion resistance and other excellent properties, the rapid development. [0003] Magnesite handicrafts use oil-based release agents in the production, the surface tension is low, and the general coating is difficult to adhere. After coating, there are defects such as poor adhesion and flakes falling off, which affect the appearance of the product. [0004] Chinese patent CN1164702C has announced a kind of water-based coating, comprises p...
