Abstract

The invention provides a special-type high-strength wear-resistant water-based epoxy paint and a preparation method thereof. The water-based epoxy paint comprises a component A and a component B. The component A comprises the following ingredients in parts by mass: 80-90 parts of water-based epoxy resin, 2-4 parts of modified compatibilizing resin and 5-15 parts of reactive diluent. The component B comprises the following ingredients in parts by mass: 40-45 parts of water-based amine hardener, 8-10 parts of tungsten carbide, 4-5 parts of spodumene, 3-5 parts of functional resin, 3-18 parts of pigment, 10-25 parts of filler, 0.1-0.5 part of defoaming agent, 0.1-0.3 part of wetting and leveling agent and 20-30 parts of water. The paint film formed by proportionally mixing the component A and component B of the water-based epoxy paint has the advantages of proper usable life, favorable constructability, favorable hardness, favorable wear resistance, favorable flexibility, favorable impact resistance, other physical and mechanical properties and chemical medium resistance, and is suitable to be used as a floor paint.

Description

technical field [0001] The invention relates to an epoxy floor coating, in particular to a special high-strength wear-resistant water-based epoxy paint and a preparation method thereof. Background technique [0002] Modern industrial floors require dust-proof, seepage-proof, corrosion-resistant, pressure-resistant, wash-resistant, etc. Epoxy floor coatings have good physical and mechanical properties and excellent chemical resistance due to the coating film, and are smooth, smooth and decorative. It is strong and can meet the requirements of modern industrial floors, so it is widely used. In recent years, with the rapid development of epoxy water-based technology, water-based epoxy paint has been developed and applied. Compared with solvent-based epoxy floor coatings, water-based epoxy paint has the following advantages: the coating has one-way air permeability, It avoids bad problems such as foaming or peeling due to moisture; using water as the dispersion medium, it is fl...
