Abstract

The invention relates to an epoxy coating and its preparation method. The coating provided by the invention comprises a component A and a component B, wherein the component A comprises 20-35 wt% of an epoxy resin liquid, 4-15 wt% of a phenolic resin liquid, 4-15 wt% of a petroleum resin liquid, 1-7 wt% of an anti-settling agent, 20-50 wt% of a filler, 4-15 wt% of a pigment, 5-20 wt% of a solvent and 0.3-5 wt% of a cosolvent; the component B comprises 30-80 wt% of a curing agent and 20-70 wt% of a solvent; and the mass ratio of the component A to the component B is 10-1:1. The coating provided by the invention has a light color, is suitable for a priming paint and a finishing coat, and has good waterproof and antirust properties.

Description

technical field [0001] The invention relates to an epoxy resin coating and a preparation method thereof, in particular to a tar-free epoxy resin coating and a preparation method thereof. Background technique [0002] The development of modern shipbuilding, shipping, transportation and other industries is inseparable from metal materials, and the surface of all unprotected metal materials will be severely corroded in the atmosphere or other corrosive environments, resulting in huge economic losses. For example, ships sailing in the ocean, because the underwater parts have been fouled by marine organisms for many years, the result of fouling not only greatly increases the weight of the hull, reduces the speed of the ship, consumes more fuel, but also greatly accelerates the corrosion of the hull. However, if the corresponding marine coatings are used for protective coating, the metal hull can be isolated from the atmosphere and other corrosive media, thereby preventing oxygen,...
