Problems solved by technology

The current coatings generally have the defect of long drying time, especially in low-temperature and high-humidity areas in the south in winter, the drying time is greatly prolonged, which not only affects the construction progress, but also because the drying time is too slow and the strength rises too slowly, it is easily damaged by rainwater. and other damage; and in the process of coating (or coating) the coating, since the coating layer has a certain thickness, it will not only affect the drying rate of the coating, but also the uniform thickness of the exterior wall coating layer is difficult to control

Embodiment 1

[0022] A coating method for a quick-drying coating for wallboards, comprising the steps of:

[0023] Step 1: Prepare coating equipment, such as figure 1 , 2 As shown, the coating equipment includes a coating plate 2 and two gripping groove-making units. A support block 3 is respectively welded on both sides of the lower end of the coating plate 2. The support block 3 is flush with the side wall of the coating plate 2. The support block The length of 3 is less than the width of coating plate 2.

[0024] The upper end of the coating plate 2 is welded with a material holding tank 4, and the coating plate 2 is provided with a strip groove 5, and the material holding tank 4 communicates with the lower end of the coating plate 2 through the strip groove 5, and the coating material is housed in the material holding tank 4; There is also a material leakage groove 6 on the plate 2, and a material delivery groove 7 is opened in the support block 3, and the material leakage groove 6 is...

Embodiment 2

[0033] On the basis of Embodiment 1, a rubber pad is stuck on the grip bar, which is convenient for manual gripping; in addition, the coating equipment also includes a delivery pump, a material holding box and a delivery pipe, and the material holding box is used to hold the ready-to-use coating after preparation , the delivery pump is set in the material storage box, the delivery pump and the material storage tank 4 are connected by a delivery tube, the delivery tube is a corrugated tube, and the delivery tube has an excess length. When the paint plate 2 moves away from the material storage box, the delivery tube can also meet Length required.

Embodiment 3

[0035] The difference from Example 1 is that a quick-drying paint formulation for wallboards includes the following raw materials: 50 g of water, 10 g of absolute ethanol, 1 g of cellulose with a viscosity of 100,000, 0.5 g of MZ bentonite, and a pH regulator 0.5g, wetting and dispersing agent 3g, ethylene glycol 8g, defoamer 0.5g, alcohol ester twelve 3g, preservative 1g, styrene-acrylic emulsion 110g, heavy calcium powder 110g, expanded perlite 8g, titanium dioxide 10g, quartz Sand 530g, thickener 1g.

Abstract

The invention relates to the field of the coating of coatings, and particularly relates to a quick-drying coating formula for a wallboard. The quick-drying coating formula comprises the following raw materials in parts by mass: 50-70 parts of water, 10-30 parts of absolute ethyl alcohol, 1-3 parts of cellulose, 0.5-1 part of MZ bentonite, 0.5-2 parts of a pH regulator, 3-5 parts of a wetting dispersant, 8-12 parts of ethylene glycol, 0.5-2 parts of a defoaming agent, 3-5 parts of texanol, 1-3 parts of a preservative, 110-130 parts of a styrene-acrylic emulsion, 110-130 parts of heavy calcium powder, 8-12 parts of expanded perlite, 10-30 parts of titanium dioxide, 630-650 parts of quartz sand and 1-3 parts of a thickening agent. The coating method of the quick-drying coating for the wallboard comprises the steps of 1, preparing coating equipment; 2, coating the coating in a flat and seamless mode; and 3, manufacturing an overflow tank. When the scheme is adopted, coating solidification can be accelerated.

Description

technical field [0001] The invention relates to the field of paint coating, in particular to a quick-drying paint formula and a paint method for wallboards. Background technique [0002] After the building exterior wall is coated with paint, it is necessary to carry out construction on the paint layer, such as brushing and other operations. The current coatings generally have the defect of long drying time, especially in areas with low temperature and high humidity in the south in winter, the drying time is greatly prolonged, which not only affects the construction progress, but also because the drying time is too slow and the strength rises too slowly, it is easily damaged by rainwater. and other damages; and during the coating (or coating) construction process of the coating, since the coating layer has a certain thickness, it will not only affect the drying rate of the coating, but also the uniform thickness of the exterior wall coating layer is difficult to control.
