Abstract

The invention belongs to the technical field of coating materials, and particularly relates to a water-based phenolic epoxy coating material and a preparation method thereof. The water-based phenolic epoxy coating material comprises a component A and a component B, wherein the component A comprises the following components in percentage by mass: 40-50% of water-based phenolic epoxy emulsion, 0.4-1% of a wetting dispersant, 0.1-0.5% of a wetting leveling agent, 0.1-0.3% of a defoaming agent, 0.1-0.5% of an anti-settling agent, 5-10% of titanium dioxide, 10-25% of a filler, 5-10% of an anti-rust pigment, 10-15% of a conductive aid, 0.5-1% of a thickening agent, 1-2% of an adhesion promoter, 2-5% of a film forming aid, and the balance of water, and the component B comprises a water-based amine adduct curing agent and water in a mass ratio of (4-6): 1. The water-based phenolic epoxy coating material disclosed by the invention has chemical resistance and heat resistance, is low in VOC content and good in chemical stability, and has wide application prospects in the fields of petrochemical pipelines, storage tanks and the like.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to a water-based novolac epoxy coating and a preparation method thereof. Background technique [0002] The form of corrosion in the petrochemical industry does not exist alone. Due to the complex organic and inorganic mixtures as the corrosive medium, the harsh application environment, etc., will cause corrosion damage to storage tanks and pipelines and cause extremely serious losses. The corrosion loss of petrochemical industry accounts for 6% of the total output value of the industry, which is more than double that of other industries. What is particularly frightening is that this kind of corrosion not only affects the quality of crude oil, but may also cause hazardous chemical accidents. Once an accident occurs, it will often cause a large number of people Casualties, environmental pollution and property losses, etc., are irreparable disasters. [0003] The interior wall coat...
