Problems solved by technology

Traditional anti-corrosion coatings, because they contain heavy metal compounds, are harmful to the environment and human body, and are gradually phased out
However, most of the anti-corrosion coatings based on environmentally friendly chlorinated rubber modified resins are used now. Its corrosion resistance and wear resistance are weak, and it has been unable to meet the new standards and requirements in the anti-corrosion market.

Abstract

The present invention discloses an epoxy resin curing agent and an epoxy resin coating material, wherein the epoxy resin curing agent mainly comprises a bisphenol A type epoxy resin, a curing agent, a diluent, a modifier, quartz powder and aluminum powder. According to the epoxy resin coating material, per 100 parts of water comprises, by mass, 46-48% of an epoxy resin, 12-14% of an epoxy resin curing agent, 17-19% of a filler, 12-14% of a pigment, and 10-12% of an auxiliary agent. The epoxy resin curing agent has characteristics of good curing property, low toxicity, strong adaptability and wide use performance. The epoxy resin coating material has characteristics of significantly-improved coating material corrosion resistance, low viscosity, fast curing, easy use, green environmental protection and high wear resistance.

Description

Technical field: [0001] The invention relates to the technical field of curing agents and the paint industry, in particular to an epoxy resin curing agent and an epoxy resin corrosion-resistant coating. Background technique: [0002] Nowadays, the curing agent used to synthesize epoxy resins usually uses ethylenediamine as the curing agent, but a highly toxic and irritating gas will be volatilized during curing, endangering human health. In addition, it cannot be used in low temperature and underwater operations or in humid environments, and the curing speed is slow. The above-mentioned curing agent has the disadvantages of low mechanical strength and high toxicity. [0003] In the field of anti-corrosion, epoxy resin anti-corrosion coating occupies an important position. Epoxy resin itself is thermoplastic and has a low molecular weight. It must be cross-linked with a curing agent to form a network-like macromolecule in order to show the advantages of epoxy resin and form...
