Problems solved by technology

[0008] In addition, when the general solvent-free epoxy coating is at a low temperature of about 70°C, the reaction speed is slow and the hardening time is long, so it is difficult to adapt to the actual coating process requirements
[0009] In addition to certain toxicity and potential safety hazards, the existing solvent-based epoxy coatings have high requirements for the surface treatment of the substrate. The coatings have many deficiencies in terms of elasticity, adhesion, construction performance, etc., and the overall performance is not excellent enough.

Abstract

The invention relates to epoxy potable water tank paint and its preparation method. The paint provided by the invention is mainly composed of a component A and a component B: 1) the component A comprises the following ingredients: by weight, 23-40% of epoxy resin, 2-12% of ethanol, 15-38% of butanone, 0.5-1.2% of fumed silica and 20-60% of pigment and filler; and 2) the component B comprises the following ingredients: by weight, 73-90% of a curing agent for epoxy resin, 2-8% of ethanol and 7-20% of butanone. The preparation method comprises the following steps: mixing epoxy resin, butanone, ethanol, pigment and filler and the auxiliary agents according to the formula ratio, dispersing, carrying out sand milling until the fineness reaches the technical requirement, filtering the obtained mixture and packaging so as to obtain the component A; and packaging the obtained component A and the component B according to the mass ratio.

Description

technical field [0001] The invention relates to the technical field of epoxy coatings, in particular to an epoxy drinking water tank coating and a preparation method. Background technique [0002] Modern material civilization is inseparable from coatings everywhere, from ships, bridges, docks, port facilities to toys and other daily necessities are all protected and decorated with coatings. [0003] Drinking water tank coating refers to the coating applied on the inner surface of the ship's drinking water tank, which has anti-corrosion properties and can ensure the quality of drinking water. Most of the existing paint products for drinking water tanks contain benzene solvents, which are harmful to the environment and construction personnel. [0004] At present, the coatings used in the drinking water tanks of ships are basically pure epoxy coatings, and their varieties include solvent-based epoxy coatings, high-solid epoxy coatings and solvent-free epoxy coatings. Due to t...
