Problems solved by technology

[0004] The coatings that can be painted with stone effects on the market mainly include multi-color paints, real stone paints, and rock flake paints. Effect, and can not achieve the texture effect of stone
Furthermore, these coatings all use water as the dispersion medium, which increases transportation costs and energy consumption.
In addition, these coatings require special construction tools for construction, mainly spraying; special construction tools make the construction more complicated and increase the difficulty of construction; spraying construction also increases energy consumption, increases noise, and atomized coatings are easy to harm the human body And enter the air to cause air dust pollution

Embodiment 1

[0027] Embodiment one: prepare imitation stone material dry powder coating of the present invention

[0028] Weigh each component according to the formula in Table 1, stir and mix each component evenly to obtain the imitation stone dry powder coating of the present invention.

[0029] Table 1

[0030] Element

Embodiment 2

[0031] Embodiment two: the construction of imitation stone material dry powder coating of the present invention

[0032] Take the imitation stone dry powder coating prepared in Example 1, add water and stir to mix evenly, and the weight ratio of coating to water mixing is 100:30.

[0033] Use batch scraping method to evenly coat the paint on the building wall to form a coating film. After 35 minutes, the coating film is dry and wet the surface of the coating film with water.

[0034] Use a brush to wipe the surface of the coating film to loosen the fine powder on the surface of the coating film from the coating film, and then immediately pour water on the surface of the coating film to completely detach the loose fine powder from the coating film, showing the Colored sand and rock flakes form a coating film with a stone-like effect.

Embodiment 3

[0035] Embodiment three: performance test of imitation stone material dry powder coating of the present invention

[0036] Each component was weighed according to the formula in Table 2, and each component was stirred and mixed evenly to obtain the imitation stone dry powder coating of each comparative example.

[0037] Table 2

[0038]

[0039] Performance tests were performed on the imitation stone dry powder coatings prepared in Example 1 and Comparative Examples 1-6, and the test results are shown in Table 3.

[0040] table 3

[0041]

[0042]

[0043] From the above test results, it can be seen that the imitation stone dry powder coating of the present invention has good scratch resistance, scrub resistance and crack resistance, and high tensile bond strength.

[0044]From the comparison of the results of Example 1 and Comparative Example 1, it can be seen that the addition of food-grade calcium hydroxide can improve the scrub resistance of the dry powder coati...

Abstract

The invention discloses a simulated stone dry powder coating and a construction method thereof. The simulated stone dry powder coating is prepared from the following raw materials in percentage by weight: 30-35% of Portland cement, 5.0-10% of VAE emulsion powder, 5.0-10% of light calcium oxide, 0.1-0.3% of polyacrylamide, 0.4-0.6% of lignocellulose, 0.2-0.4% of hydroxypropyl methyl cellulose ether, 0.1-0.3% of water reducer, 5.0-30% of quartz powder, 5.0-30% of quartz sand, 10-30% of color sand, 1.0-10% of rock slice and 0.0-3.0% of color powder. The simulated stone dry powder coating can generate a visual effect of a stone, can generate a texture effect of the stone, can be directly constructed in a dry powder manner and is simple in construction and environmentally friendly.

Description

technical field [0001] The invention relates to a building coating and a construction method thereof, in particular to a stone imitation dry powder coating and a construction method thereof. Background technique [0002] Coating refers to the general term for materials that can form a tough protective film applied to the surface of objects. Architectural coatings are an important category of coatings. In China, coatings used for interior walls, exterior walls, ceilings, floors, and toilets are generally called For architectural coatings. [0003] Generally speaking, architectural coatings have the functions of decoration, protection and habitability improvement. Compared with other decorative materials, architectural coatings are safe, energy-saving, convenient for construction, low in price, and have obvious effects. As people return to the basics and get close to the natural psychology, architectural decorative coatings that can be painted with stone effects and whose pr...
