A kind of quick-drying coating formula and coating method for wallboard

Abstract

The invention relates to the field of paint coating, in particular to a quick-drying paint formula for wallboards, comprising the following raw materials in parts by mass: 50-70 parts of water, 10-30 parts of absolute ethanol, and 1-3 parts of cellulose , 0.5-1 part of MZ bentonite, 0.5-2 parts of pH regulator, 3-5 parts of wetting and dispersing agent, 8-12 parts of ethylene glycol, 0.5-2 parts of defoamer, 3-5 parts of alcohol ester twelve, 1-3 parts of preservative, 110-130 parts of 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, 1-thickener 3 parts; a coating method for quick-drying coatings for wallboards, comprising the following steps: Step 1: preparing coating equipment; Step 2: coating the coating evenly and seamlessly; Step 3: making overflow tanks. When this scheme is adopted, it is beneficial to accelerate the solidification of the coating.

Description

Technical field [0001] The present invention relates to the field of coating coating, specifically to a fast-drying coating formulation for wall panels and a coating method. Background [0002] After the exterior walls of the building are coated with paint, construction needs to be carried out on the paint layer, such as brushing and other operations. The current paint generally has the defect of a long drying time, especially in the winter in the south of the low temperature and high humidity and other areas, the drying time is greatly extended, not only affecting the construction progress, and because the drying time is too slow, the strength rise is too slow, it is easy to be damaged by rainwater, etc.; and in the process of coating (or coating) construction of the coating, because the coating layer has a certain thickness, it will not only affect the drying rate of the coating, but also the thickness of the outer wall coating layer is uniform and difficult to control.

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
