Abstract

The invention relates to water-based paint, which comprises the following raw materials by part by weight: 52 to 55 parts of water, 0.5 to 0.7 part of sodium dodecyl sulfate, 30 to 70 parts of emulsion or aqueous dispersoid resin, 0.8 to 1 part of ammonia water, 0.1 to 0.2 part of defoamer, 0.05 to 0.1 part of sodium acetate, 0.5 to 5 parts of germicide, 0.1 to 1 part of corrosion inhibitor and 0.1 to 0.2 part of potassium peroxydisulfate. The invention further provides a preparation method for the water-based paint. The water-based paint is non-poisonous and harmless and causes little pollution to the environment. A coating formed by applying the water-based paint has high brightness and excellent firmness and resistance to crack, is hard to a certain extent, contains few VOCs and no heavy metal and have the functions of antibiosis and both mold and rust prevention. Therefore, the water-based paint is environmentally friendly and safe.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a low-VOC, heavy metal-free water-based paint with antibacterial, anti-mildew and anti-rust functions and a preparation method thereof. Background technique [0002] Coatings include water-based coatings and solvent-based coatings. Although the coatings formed by some oil-based coatings can meet the requirements of high brightness and subsequent rapid bronzing processing, they will volatilize more harmful substances during use, causing great environmental pollution. Reach environmental protection requirements (especially the organic volatile matter limit requirements of the cigarette pack industry), and the cost is relatively high. [0003] Water-based paint is a paint that mainly uses water as a solvent. Water-based coatings have many advantages. For example, water-based coatings use water as a solvent, saving a lot of resources; water-based coatings eliminate the fire hazard during const...
