Abstract

The invention relates to the technical field of coating and in particular discloses double-component quick-dry wear-resisting waterborne epoxy coating and a preparation method thereof. The double-component quick-dry wear-resisting waterborne epoxy coating is prepared from a component A and a component B, wherein the mass ratio of the component A to the component B is (5 to 7) to 1; the component Ais prepared from the following raw material components in percentage by mass: 45 to 55 percent of waterborne epoxy emulsion, 0 to 0.5 percent of an anti-rust auxiliary agent, 2 to 3 percent of a dispersant, 0.3 to 0.4 percent of a de-foaming agent, 4 to 6 percent of an environment-friendly co-solvent, 30 to 40 percent of pigment and filler, 0.5 to 1 percent of an anti-sedimentation agent, 0.5 to1 percent of a base material wetting agent, 5 to 13 percent of de-ionized water and 1 to 2 percent of a thickening agent; the component B is prepared from the following raw material components in percentage by mass: 65 to 75 percent of an amine curing agent and 25 to 35 percent of de-ionized water. The double-component quick-dry wear-resisting waterborne epoxy coating provided by the invention hasthe characteristics of rapid drying speed, good adhesive force, high rigidity, excellent wear resistance and anticorrosion performance.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component quick-drying wear-resistant water-based epoxy coating and a preparation method thereof. Background technique [0002] Traditional solvent-based two-component epoxy coatings have excellent properties such as low film forming temperature, strong adhesion, good wear resistance, and high hardness. They are widely used as primers for industrial protection, wood furniture and automobiles. However, with the continuous implementation and improvement of environmental protection policies and the continuous enhancement and improvement of consumers' environmental awareness, traditional oil-based paints are gradually being replaced by environmentally friendly paints. Among them, environmentally friendly paints represented by water-based paints are flourishing in modern green paints. important parts of. Water-based paint is recognized by consumers for its low VOC, energy-saving, n...
