Abstract

The invention discloses a preparation process of water-based paint. According to the technical scheme, the preparation method is characterized by specifically comprising the following steps: selectingraw materials: selecting the following components, by weight: 300-400 parts of water, 100-120 parts of acrylic resin, 150-180 parts of epoxy resin, 10-15 parts of fluorescent powder, 20-30 parts of ethylene glycol, 20-30 parts of propylene glycol monomethyl ether, 20-30 parts of a pure acrylic emulsion, 20-30 parts of coloring raw materials, 5-10 parts of a defoamer, 5-10 parts of a dispersant, 5-10 parts of a preservative, 5-10 parts of a wetting agent and 10-20 parts of a leveling agent, and 10-18 parts of a pH regulator; the water-based paint prepared by the preparation process of the water-based paint adopts the coloring agent and the fluorescent powder, so that the water-based paint is relatively bright and can generate weak fluorescence to a certain extent, and the night vision property is improved; the leveling agent is used in the raw materials, so that the water-based paint has self-leveling capability; and the defoaming agent and the wetting agent are adopted, so that the prepared water-based paint has fewer bubbles.

Description

technical field [0001] The invention relates to the field of water-based paint processing, in particular to a preparation process of water-based paint. Background technique [0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres firmly to the continuous coating film. Water-soluble coatings are coatings based on water-soluble resins and water is the solvent. Water-based coatings have a tendency to gradually replace organic solvent-based coatings. [0003] Existing notification number is the Chinese patent of CN110845932A, and it discloses a kind of preparation technology of water-based coating, and it comprises the following steps: S1 step: according to weight part, benzoyl peroxide is dissolved in mixed acrylate monomer, then Mix with modified polyurethane, stir at 50-55°C for 2-3h until the modified polyurethane is completely dissolved to obtain the first mi...
