Water-based integrated ceiling finish paint compounded from various emulsions and preparing method thereof

Abstract

The invention discloses water-based integrated ceiling finish paint compounded from various emulsions and a preparing method thereof. The water-based integrated ceiling finish paint compounded from various emulsions comprises, by weight, 42-48 parts of the hydroxyacrylic acid emulsion, 4.5-6.5 parts of the silicone acrylic emulsion, 25.5-26.5 parts of titanium dioxide slurry, 5-6.5 parts of waterborne polyurethane dispersoid, 0.25-0.35 part of a defoaming agent, 0.2-0.3 part of a pH regulator, 3.7-4.5 part of water-based amino resin, 0.75-0.85 part of a thickening agent, 0.06-0.08 part of a flatting agent and 28.04-6.02 part of water. The titanium dioxide slurry comprises, by weight, 25-26 parts of water, 0.2-0.3 part of a preservative, 0.02-0.04 part of a defoaming agent, 0.25-0.35 part of a wetting agent, 2.5-3.5 parts of a dispersing agent and 71-73 parts of titanium dioxide. The prepared water-based integrated ceiling finish paint is free of toxin and environmentally friendly, thewater-based performance and environmentally friendliness in the production process can be ensured when the water-based integrated ceiling finish paint is used for the finish of an integrated ceiling,and the protection environment of a workshop and the mental and physical health of production workers can be easily protected.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to the technical field of a water-based integrated ceiling finish coating compounded by various emulsions and a preparation method thereof. 【Background technique】 [0002] In the past two decades, China's interior furnishing industry has formed a unique integrated ceiling industry in the world, especially an industrial cluster with aluminum formwork as the main body in Zhejiang. The finishing paint of the existing integrated ceiling adopts oil-based baking varnish, and the coating adopts the method of high-temperature reaction of roller coating material to form a film. The coiled aluminum plate generally adopts 0.4mm thick aluminum plate, after pickling, drying, roller coating, It is prepared by processes such as drying, printing, cutting and stamping. The main production process parameters are: [0003] 1) Dry film thickness: about 17μm; [0004] 2) Drying temperature: around...

AI Technical Summary

Problems solved by technology

The above indicators are quite different from the indicators of the integrated ceiling finish paint, and none of them can meet the multiple performance requirements listed in the above table 1

Major performance deficiencies include insufficient flexibility, solvent resistance, and boiling water resistance of the emulsion polymer

However, flexible emulsion polymers cannot reach the required hardness and adhesion, and the solvent resistance and boiling water resistance of flexible polymers will generally be further reduced.
