Abstract

The invention discloses a low VOC and high adhesion alkali-resistant floor primer water paint and a preparation method thereof. The low VOC and high adhesion alkali-resistant floor primer water paint comprises the following components by mass percentage: 55-65% of water-borne epoxy resin, 8-13% of a water-borne macromolecular epoxy curing agent, 1-3% of an environment-friendly neutralizer, 10-15% of deionized water, 1-2% of a special substrate adhesive agent, 1-2% of an adhesion promoter, 0.5-1% of a defoaming agent, 2-4% of a high efficiency penetrant, 5-6% of an anti-pinhole leveling agent, 1-2% of an alkali-resistant bactericide, and 0.5-1% of a polyurethane thickener. The floor primer water paint provided by the invention has the advantages of good alkali resistance, strong corrosion resistance, low VOC, fast drying, and strong bacteria resistance and bacteriostasis and adhesive force.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a low-VOC, high-adhesion and alkali-resistant floor primer water paint and a preparation method thereof. Background technique [0002] With the enhancement of environmental regulations and people's awareness of environmental protection, water-based floor coatings will be widely used, and the research and development of water-based floor coatings will have great economic and social benefits. Water-based floor coatings have comparable performance to solvent-based floor coatings. Existing water-based floor coatings can be used in production plants, office buildings, warehouses, and laboratories in pharmaceutical, food, hospital, textile, chemical, and electronics industries. Ping coating, especially suitable for the first floor, basement, underground parking lot and other relatively humid environments. As a green environmental protection product, water-based floor paint must be recognized a...
