Abstract

The invention relates to the technical field of chemical materials, in particular to non-toxic long-acting solvent-free drinking water cabin paint and a preparation method thereof. The non-toxic long-acting solvent-free drinking water cabin paint comprises a component A and a component B, wherein the component A comprises epoxy resin, dimer acid modified epoxy resin, an amino silane coupling agent, a dispersing agent, a defoaming agent, non-toxic filler, glass flakes, a nanometer double-layer material and a thixotropic agent; the component B comprises an amine curing agent and an epoxy silanecoupling agent. Compared with the prior art, the non-toxic long-acting solvent-free drinking water cabin paint prepared through the preparation method is lower in VOC, and the VOC is lower than 50 g / L; the mixing viscosity is moderate, the salt fog resistance is excellent, and the salt fog resistance reaches 5000 h when the thickness of a dry film is 250 micron. Besides, the adhesive force is notlower than 11 MPa; through a sanitary performance test, long-acting anti-corrosion protection requirements of a drinking water cabin, drinking water conveying and distributing water pipelines and theinner wall of equipment are met.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a non-toxic, long-lasting solvent-free drinking water tank coating and a preparation method thereof. Background technique [0002] At present, most of the anti-corrosion coatings used for drinking water tanks, drinking water transmission and distribution pipelines and the inner walls of equipment are solvent-based epoxy coatings and solvent-free epoxy coatings. Among them, the solvent-free epoxy coating does not contain volatile solvents (VOC), has the characteristics of less volatile substances after film formation, low VOC emissions, and does not pollute water quality. Sanitation and safety of water quality and water quality provide a reliable guarantee, which is an important development trend of coatings for drinking water tanks. [0003] However, drinking water tanks and drinking water distribution pipelines and equipment generally have the characteristics of narr...
