Problems solved by technology

[0002] At present, there are various grades of indoor top surface decoration materials on the market, and they are generally made of aluminum, rock wool, calcium carbonate or gypsum ceiling panels, and their decorative effects are relatively simple.
The surface of the aluminum ceiling board is relatively smooth, the cost is also high, and it reflects light greatly, causing a large contrast in the indoor light effect and giving people a bad visual effect; the ceiling board made of rock wool is light in weight, but its waterproof effect is poor. After a long time, it is easy to sag due to moisture; the ceiling board made of calcium carbonate or gypsum is easy to break, causing inconvenience in construction, and easy to absorb water

Embodiment 1

[0017] Take 8 parts of synthetic solid melamine formaldehyde resin, 0.3 part of dispersant, 0.3 part of thickener, 20 parts of kaolin, 20 parts of calcium carbonate, 0.2 part of defoamer, and 51.2 parts of water. Pour water into the reaction kettle, add condensed phosphate dispersant to disperse at high speed for 5 minutes, add hydroxymethyl cellulose to disperse at high speed for 5 minutes, add calcium carbonate and kaolin to disperse at high speed for 35 minutes, add melamine formaldehyde resin emulsion and stir at slow speed for 10 minutes, add The defoamer was stirred at a slow speed for 5 minutes, and the stirring was stopped to obtain a back coating.

[0018] The construction process of the present invention includes the following three processes: base plate test → roller coating and back coating → high temperature baking (crosslinking and curing).

[0019] The specific construction process is as follows:

[0020] 1. Base plate test:

[0021] The base plate must be cle...

Embodiment 2

[0028] Take 20 parts of synthetic liquid melamine formaldehyde resin, 0.3 part of dispersant, 0.3 part of thickener, 20 parts of kaolin, 20 parts of calcium carbonate, 0.2 parts of defoamer, and 39.2 parts of water. Pour water into the reaction kettle, add condensed phosphate dispersant to disperse at high speed for 5 minutes, add hydroxymethyl cellulose to disperse at high speed for 5 minutes, add calcium carbonate and kaolin to disperse at high speed for 35 minutes, add melamine formaldehyde resin emulsion and stir at slow speed for 10 minutes, add The defoamer was stirred at a slow speed for 5 minutes, and the stirring was stopped to obtain a back coating.

Abstract

The invention discloses a preparation and a construction process for a back-coating used for a mineral cotton ceiling floor. The back-coating used for the mineral cotton ceiling floor is a liquid-typelayer material. The construction process comprises three procedures of testing substrate plates, rolling and coating the back-coating and high-temperature baking (crossing and curing). The back-coating used for the mineral cotton ceiling floor has the advantages of quick crossing speed, high compactness, large tensile strength, excellent fire-proof and moisture-proof function, reinforcing the tensile strength of the plate, mildew resistance, reducing noise, long service life, yellowing resistance, low VOC, convenient construction, etc. The back-coating used for the mineral cotton ceiling floor is matched with the mineral cotton ceiling floor, has unique moisture-proof, air-permeable and anti-settlement effects, can ensure the long-term smooth visible effect of the ceiling and is applicable to the decoration of ceiling finishes of various top-grade buildings.

Description

Technical field: [0001] The invention relates to a back-coating paint for a mineral wool ceiling board and a construction process, in particular to a back-coating paint for a mineral wool ceiling board constructed on a mineral wool ceiling board and a construction process. Background technique: [0002] Various grades of interior top surface decoration materials appear on the market at present, generally all are the ceiling panels of aluminum material, rock wool, calcium carbonate or gypsum material, and its decorative effect is relatively simple. The surface of the aluminum ceiling board is relatively smooth, the cost is also high, and it reflects light greatly, causing a large contrast in the indoor light effect and giving people a bad visual effect; the ceiling board made of rock wool is light in weight, but its waterproof effect is poor. After a long time, it is easy to sag due to damp; the ceiling board made of calcium carbonate or gypsum is easy to break, causing incon...
