preparation example Construction

[0025] Meanwhile, the present invention provides the preparation method of above-mentioned waterborne paint, and this preparation method specifically comprises following operation steps:

[0026] (1), preparation of 7% special silicate liquid: take and prepare the following components by weight: 928 parts of water, 2 parts by weight of industrial preservatives, and 70 parts of special silicate, mix each component and Disperse at a speed of 800r / min until uniform and particle-free to obtain a 7% special silicate solution for use;

[0027] (2) Preparation of base material: Weigh and prepare the following components by weight: 221.5 parts of water, 1 part of AMP95 multifunctional additive, 1 part of industrial preservative, 10 parts of propylene glycol, 10 parts of lauryl alcohol, silicon 250 parts of acrylic emulsion, 6 parts of 50% TT-935 thickener, and 0.5 part of mineral oil defoamer; first mix water, AMP95 multifunctional additive, industrial preservative, propylene glycol, ...

Embodiment 1

[0033] Weigh 928kg of water, 2kg of industrial preservative, and 70kg of special silicate, mix the components and disperse at a high speed of 800r / min until uniform and particle-free to obtain 1000kg of 7% special silicate solution, which is ready for use;

[0034] Weigh 221.5kg of water, 1kg of AMP95 multifunctional additive, 1kg of industrial preservative, 10kg of propylene glycol, 10kg of lauryl alcohol fat and 250kg of silicon acrylic emulsion and mix them, and stir at a low speed of 400r / min until uniform, and add 6kg of 50% TT-935 thickener, after being completely stirred evenly, add 0.5kg of mineral oil defoamer, and continue to stir until evenly to obtain 500kg of base material for use;

[0035] Weigh 490kg of water, 2kg of industrial preservatives, 4kg of anionic surfactants, 10kg of propylene glycol, 8kg of lauryl alcohol, and 2kg of mineral oil defoamers and mix them evenly at a stirring rate of 400r / min; then add 25kg of silicone Resin, stir evenly at a stirring rate...

Embodiment 2

[0038] Compared with embodiment 1, the differences in this embodiment are:

[0039] (a) Take by weighing 490kg water, 2kg industrial preservative, 4kg anionic surfactant, 10kg propylene glycol, 8kg lauryl alcohol fat, and 2kg mineral oil defoamer and mix, then adopt a stirring rate of 600r / min to stir evenly; ( b) After putting in 25kg of silicone resin, the stirring rate used is 600r / min; (c) 2kg of polyurethane thickener is added at a revolution of 900r / min; (d) after adding polyurethane thickener, use 900r / min Min stirring speed stirring 10min.

Abstract

The invention provides a water-based coating. The water-based coating is prepared from the following components in parts by weight: 20 parts of 7% special silicate liquid, 5 parts of water, 40 parts of basic paint and 35 parts of a base material. The water-based coating has good color retention property; and by utilizing pearl powder, the water-based coating has multiple colors, so that the defectthat an existing water-based coating is relatively single in color is solved, and the water-based coating can be well favored by customers. Furthermore, the invention simultaneously discloses a preparation method of the water-based coating. The preparation method has the beneficial effects that the preparation process is easily operated, the material is conveniently acquired, and the cost is relatively low.

Description

【Technical field】 [0001] The invention relates to decoration materials used in the construction field, in particular to a water-based paint and a preparation method thereof. 【Background technique】 [0002] Water-based paint is a paint that uses water as a medium and diluted. Compared with organic solvent paint, water-based paint not only reduces the emission of organic solvents (VOC) but also saves organic material resources, thereby greatly reducing the impact of organic solvent volatilization on the atmosphere in the paint. Pollution and fire hazards during construction. Water is an extremely abundant resource on the earth. It is easy to use and low in cost. It is used as a solvent in paint and will not cause damage to water resources or less. Therefore, water-based coatings not only reduce the emission of volatile organic solvents, but also save resources and energy, and are convenient for transportation and storage. With the enhancement of people's awareness of environm...
