Abstract

The invention relates to self-emulsifying fluorosilicone modified dual-component waterborne epoxy floor coating. The floor coating is characterized in that the floor coating includes an A component and a B component; the A component includes, by weight, 30-40 parts of an amine curing agent, 3-5 parts of a zirconate coupling agent and 0-20 parts of an alcohol diluent; the B component includes 50-80parts of emulsifiable organic fluorosilicone epoxy resin, 0.5-1 part of a leveling agent, 0.8-1.5 parts of a wetting and dispersing agent, 0.1-0.3 part of a defoamer and 15-50 parts of a pigment filler; the emulsifiable organic fluorosilicone epoxy resin is used for the waterborne epoxy floor coating so that the floor coating has a self-emulsifying property, can be directly emulsified with waterand diluted and is waterborne and environmentally friendly; through modification with fluorosilicone, water resistance, corrosion resistance and hydrophobicity of the floor coating are improved; and the process is simple, convenient to operate and prone to industrial production.

Description

technical field [0001] The invention relates to an epoxy floor paint, in particular to a self-emulsifying fluorine silicon modified two-component water-based epoxy floor paint, which belongs to the technical field of water-based paint. Background technique [0002] The epoxy resin structure contains active groups such as epoxy groups, hydroxyl groups and ether bonds, and has many excellent electrical insulation properties, physical and mechanical properties, corrosion resistance and bonding properties. It penetrates into people's lives directly or indirectly. In all aspects, in the economic and high-tech fields, such as aerospace, anti-corrosion coatings, building materials, industrial floor coatings, etc. Epoxy resin coatings are generally divided into solvent-based epoxy resins and water-based epoxy resins. With the development of world economy and science and technology, people's awareness of environmental protection is increasing day by day. Solvent-based epoxy resin i...
