Embodiment 1

[0017] 1. Attach a layer of kraft cardboard-like gypsum board on the surface to connect the gap, and use the method of scraping putty to make the surface of the joint smooth, and the height of the putty surface at the joint is less than 0.5mm above the surface of the gypsum board. And the joints and plasterboard surface are excessively smooth.

[0018] 2. Set the temperature of the coating environment at about 6°C and the relative humidity at about 40%; use water-based latex paint as the coating material, and adjust the viscosity of the water-based latex paint to 4000mpa.s; choose 200-250mm rolling short-haired wool brush.

[0019] 3. Start painting, the method of painting is roller brush and roller coating, the coating speed is controlled at 0.5m / s, the coating thickness is 30μm / time, and the roller coating is 3 times with an interval of 2 hours between each time. The total thickness is controlled at 90 μm.

[0020] 4. After the coating is completed, the inspection is carri...

Embodiment 2

[0022] 1. A layer of glass fiber cloth is attached to the outer surface of the gypsum board, and the gap between the gypsum boards is connected, and the putty method is used to make the surface of the joint smooth, and the putty surface at the joint is higher than the height of the surface of the gypsum board Less than 0.5mm, and the joints and the surface of the gypsum board are too smooth.

[0023] 2. Set the temperature of the coating environment at about 10°C and the relative humidity at about 50%; use water-based latex paint as the coating material, and adjust the viscosity of the water-based latex paint to 5000mpa.s; use a spray gun for spraying.

[0024] 3. Start coating, the coating method is spraying method, the coating speed is controlled at 0.6m / s, the coating thickness is 40μm / time, spraying 3 times, each interval is 3 hours, the total thickness of coating is 120 μm.

[0025] 4. After the coating is completed, the visual inspection method is used. The appearance o...

Abstract

The present invention provides a coating process for the external laminate layer of gypsum board, which includes setting the conditions for coating the external laminate layer of the gypsum board. The coating environmental conditions are that the temperature is above 5°C and the humidity is between 0 and 75%; Set the viscosity of the coating material to 1000 to 8000mpa.s, the coating speed to 0.2 to 1m / s, and the coating tool to be a soft brush or spray gun; times; simplify the coating process, shorten the construction period, reduce the cost by 10 to 12 yuan per square meter, and improve the coating quality and use effect.

Description

technical field [0001] The invention relates to a cardboard coating process, in particular to a process-simplified and cost-reduced coating process for an outer laminated layer of a gypsum board. Background technique [0002] At present, in most factory workshops, laboratories and home decoration, wall panels and partitions are made of gypsum boards, especially in production workshops and laboratories, because gypsum boards have light weight, environmental protection and good fire resistance. specialty. In order to achieve a beautiful and durable effect after decoration, it is generally necessary to attach a gypsum board to the outside of the board, and then paint various colors of water-based latex paint on the board, so as to achieve the effect of beauty and strength. [0003] The coating process of the existing gypsum board outer layer is to scrape and coat 2 to 3 layers of putty on the outer layer of gypsum board to fill up the seams and potholes existing on the surface...
