Problems solved by technology

[0003] At present, when the existing water-based paints on the market are used, the water-based paints are prone to precipitation and stratification during the long-term storage process, and the water-based paints are placed in a warm room when the external temperature is low, which is easy to cause Flocs appear inside the water-based paint, which affects the use of water-based paint;
[0004] Moreover, when the existing water-based paint grinder is in use, when the paint raw material is ground, it is prone to incomplete grinding, and the incompletely ground paint raw material will be directly discharged along with the raw material, requiring staff to filter the ground paint, And repeated grinding, resulting in a reduction in the efficiency of coating raw material grinding, affecting the processing and production efficiency of water-based coatings

Abstract

The invention discloses a preparation process of a high-stability water-based paint. The high-stability water-based paint is prepared from the following components in parts by weight: 80 to 120 partsof water-based resin, 7-12 parts of nano-calcium carbonate, 3-9 parts of a coalescing agent, 0.5-1.5 parts of a preservative, 8-12 parts of talcum powder, 0-24 parts of a pigment, 0.4-1.2 parts of a thickening agent, 0.2-0.6 part of a dispersing agent, 0.1-0.6 part of a defoaming agent and 40-60 parts of deionized water. The preparation method is scientific and reasonable in structure and safe andconvenient to use, the prepared water-based paint is optimal in storage stability, precipitation and layering are not likely to occur after long-time storage, the freeze-thaw stability is optimal, flocculates cannot occur after freezing and thawing, the PH value of the prepared water-based paint is closer to be neutral, and the corrosivity is lower.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a preparation process of high-stability water-based paints. Background technique [0002] Water-based coatings include water-soluble coatings, water-diluted coatings and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-formers, represented by polyvinyl alcohol and its various modified products. In addition, there are Water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer water-based resin, etc., water-based coatings need to go through material selection, stirring, crushing and grinding, secondary feeding and stirring, and filtration and screening in the process of production and packaging; [0003] At present, when the existing water-based paints on the market are used, the water-based paints are prone to precipitation and stratification during the long-term storage process, and the water-based paints are placed in...
