A kind of water-based thick coating type water-based acrylic hybrid epoxy floor paint and preparation method thereof

Abstract

The invention relates to an aqueous thick coating type aqueous acrylic hybrid epoxy floor paint, which comprises a component A and a component B, wherein the component A comprises, by weight, 60-72% of an aqueous acrylic hybrid epoxy resin emulsion, 3-5% of a pigment, 2-8% of titanium dioxide, 2-15% of precipitated barium sulfate, 1-2% of a hardening anti-wear agent, 0.3-0.5% of an aqueous dispersion agent, 0.1-0.2% of an aqueous defoamer, 0.2-0.3% of an aqueous leveling agent, 0.2-0.4% of a surfactant, 0.5-1% of an aqueous polyamide wax slurry, 7-10% of deionized water, 2-3% of a film formingaid, 3-5% of a cosolvent, 0.3-0.6% of a coating material neutralizing agent, and 1-2% of an aqueous graphene slurry, and the component B is an epoxy curing agent. The aqueous thick coating type aqueous acrylic hybrid epoxy floor paint of the present invention has advantages of fast drying, no foaming during thick coating, good leveling property, good wear resistance, good water resistance, good chemical resistance, high gloss, good weather resistance, low VOCs and the like.

Description

technical field [0001] The invention relates to a water-based thick coating type water-based acrylic hybrid epoxy floor paint and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] With the vigorous improvement of the environment across the country, local governments and various industries have also issued relevant oil ban policies. The China Flooring Association also stipulated that some provinces and cities across the country responded to the call of the local government and banned the use of solvent-based epoxy floor paint and solvents. Type acrylic polyurethane floor paint, but after a period of market verification, there are many construction problems in water-based epoxy floor paint, such as: 1. The humidity is too high, the drying is too slow, and the film-forming effect of the floor paint is very poor, resulting in A series of problems such as low hardness, low gloss, poor water resistance, poor wear resistance, ...

Problems solved by technology

[0002] With the vigorous improvement of the environment across the country, local governments and various industries have also issued relevant oil ban policies. The China Flooring Association also stipulated that some provinces and cities across the country responded to the call of the local government and banned the use of solvent-based epoxy floor paint and solvents. Type acrylic polyurethane floor paint, but after a period of market verification, there are many construction problems in water-based epoxy floor paint, such as: 1. The humidity is too high, the drying is too slow, and the film-forming effect of the floor paint is very poor, resulting in A series of problems such as low hardness, low gloss, poor water resistance, poor wear resistance, poor adhesion, floating color and fading; 2. The usable time of water-based epoxy floor paint is too short, generally only about 1 hour, which cannot meet the on-site construction Requirements; 3. Compared with solvent-based epoxy flooring, water-based epoxy flooring has low gloss, short service life, and poorer appearance than solvent-based epoxy flooring, resulting in poor market acceptance; 4. During the construction process, construction personnel Fans must be used around to strengthen the convection of the underground garage and speed up the evaporation of water. There is no problem with the garage with a small area. When the area exceeds 50,000 square meters, it cannot be operated at all.
