Abstract

The invention discloses a waterborne double-component epoxy resin coating containing an UV (ultraviolet) curable waterborne fluorine-containing epoxy curing agent. The waterborne double-component epoxy resin coating is composed of the following components in parts by weight: 20-30 parts of the UV curable waterborne fluorine-containing epoxy curing agent, 80-100 parts of waterborne epoxy resin emulsion, 20-30 parts of trimethylolpropane triacrylate, 3-6 parts of a photoinitiator, 1-3 parts of a levelling agent, and 0.2-1 part of a wetting dispersant. The preparation method comprises the following steps of: uniformly mixing and dispersing the UV curable waterborne fluorine-containing epoxy curing agent with trimethylolpropane triacrylate at first; then adding the levelling agent, the wetting dispersant and the photoinitiator, and uniformly stirring to prepare a varnish; and then adding the waterborne epoxy resin emulsion, and uniformly mixing and stirring to obtain the waterborne double-component epoxy resin coating containing the UV curable waterborne fluorine-containing epoxy curing agent. The coated film obtained after coating and curing the waterborne double-component epoxy resin coating is good in flexibility, water resistance and alkali resistance, and small in contact angle for water.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a water-based two-component epoxy resin coating containing a UV-curable water-based fluorine-containing epoxy curing agent and a preparation method and application thereof. Background technique [0002] Due to the advantages of water-based epoxy resin coatings in terms of ecology, health and safety, the applicability to various substrates and excellent coating performance, strong adhesion to concrete, excellent wear resistance, water resistance, and water resistance Chemicals and other advantages make it have many successful application examples in China in terms of industrial floors, food workshops and large parking floors. [0003] Common water-based epoxy resin coatings are mostly two-component systems formed by water-based epoxy resin emulsion and water-based epoxy curing agent. Like solvent-based systems, waterborne two-component epoxy coatings are als...
