Problems solved by technology

[0004] When the ambient temperature is lower than 10°C, the film-forming reaction speed is slow and cannot fully react, especially when the ambient temperature is below 0°C, it is difficult for ordinary amine curing agents and epoxy resins to cure and form a film, and the ambient temperature in winter in the north is often maintained. At around -10°C, due to the low ambient temperature, the construction period of the anti-corrosion project is delayed. It can be seen that the low-temperature curing performance of the existing epoxy resin coatings can no longer meet the actual needs.

Abstract

The invention discloses a low-temperature-cured liquid-state anticorrosive epoxy resin coating and a preparation method thereof. The coating is prepared from A liquid and B liquid. The A liquid is prepared from modified bisphenol-A epoxy resin, bisphenol-F epoxy resin, aliphatic glycidol ether, styrene alcohol, wollastonite powder, sericite powder, titanium dioxide, carbon black, a low-molecular-weight unsaturated carboxylic acid polymer, a polyether-modified poly-methyl alkyl siloxane solution and organobentonite. The B liquid is prepared from a modified aliphatic amine curing agent and a mercaptan amine curing agent. The preparation method comprises the steps that the A liquid and the B liquid are prepared separately and then mixed evenly to obtain the coating. The obtained coating has the good low-temperature curing property, and the preparation method has the advantages that the technology is simple, and the coating with the good low-temperature curing property can be prepared without needing special equipment.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings and preparation methods thereof, in particular to a low-temperature curing liquid epoxy resin anticorrosion coating and a production method thereof. Background technique [0002] Epoxy resin coatings are widely used in heavy-duty anti-corrosion engineering projects due to their excellent performance and chemical resistance. In the anti-corrosion epoxy resin coating system, amine curing agent is usually used for film-forming reaction with epoxy resin. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] When the ambient temperature is lower than 10°C, the film-forming reaction speed is slow and cannot fully react, especially when the ambient temperature is below 0°C, it is difficult for ordinary amine curing agents and epoxy resins to cure and form a film, and the ambient temperature in winter ...
