Abstract

The invention relates to the technical field of paint, in particular to a two-component high-hardness waterborne specially-clear primer and a preparation method thereof. The primer includes an A component, a B component and water. The B component is waterborne polyisocyanate. The A component includes crosslinked acrylic resin, a polysiloxane defoamer, an organosilicon leveling slipping agent, a polyether modified wetting agent, a polymer dispersant, zinc stearate, dipropylene glycol methyl ether, dipropylene glycol butyl ether, a polyurethane associated type rheological auxiliary agent, and water. Through synergistic effects of all components, waterproofness and chemical resistance of waterborne wood paint can be effectively improved, and paint film hardness, fullness, clarity and anti-blocking properties are improved. The method has characteristics of simplicity, strong operability and low production cost, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a two-component high-hardness water-based special clear primer and a preparation method thereof. Background technique [0002] Currently used in home decoration, wood coatings in furniture production are basically solvent-based coatings, which contain a large amount of volatile organic compounds, which in turn makes the indoor VOC content high, leading to environmental pollution and damage to the health of painters and consumers. It is inflammable and explosive, and wastes oil resources. Therefore, in order to improve the above-mentioned defects, water-based wood coatings have appeared. Water-based wood coatings use water as the dispersion medium, which has the advantages of low VOC content, low odor, no triphenyl, free TDI, no harm to human body, and no pollution to the environment. However, the water-based wood primers in the prior art have disadvantages such as poor water res...
