Environment-friendly nano-epoxy silicone heavy anti-corrosion coating and preparation method and using method thereof

Abstract

An environment-friendly nano-epoxy silicone heavy anti-corrosion coating comprises a component A and a component B, wherein the component B is polyamide, and the component A is prepared by water-borne epoxy resin, a solvent, silicon carbide, aluminum oxide, nano-quartz powder, titanium dioxide power, zinc powder, aluminum powder, ceramic powder, cobalt-nickel ultrafine metal powder and graphite. A using method of the environment-friendly nano-epoxy silicone heavy anti-corrosion coating is that the component A and the component B are mixed evenly according to the weight ratio of 30-50:1 and then directly sprayed or brushed on the surface of an anti-corrosion object at the normal temperature. A coating layer formed by the coating has good abrasion resistance, corrosion resistance, impact resisting performance and flexibility and can effectively isolate corrosion of acid, alkali, salt and sea water. The surface of the coating layer is compact and smooth and has small resistance to a transmission medium. The coating can be widely applied to oil transportation pipelines, oil storage tanks, chemical equipment, ships, grinding wheel blades, pumps, dust removers, offshore steel structures and the like. In addition, the environment-friendly nano-epoxy silicone heavy anti-corrosion coating is water-based coating, does not contain harmful ingredients and is convenient and efficient in use.

Description

technical field [0001] The invention relates to coatings, in particular to an environment-friendly nano-epoxy silicon heavy-duty anti-corrosion coating and its preparation method and application method. Background technique [0002] With the rapid development of the marine economy, the process of using marine space is accelerating, and marine structural engineering, such as breakwaters, wharves, sea airports, submarine tunnels and sea-crossing bridges, has become more and more widely used. At the same time, due to long-term immersion in seawater, erosion, and the impact of wind waves and tides, the corrosion problem of marine structural engineering has become increasingly prominent, seriously endangering the safety and durability of marine structural engineering. Therefore, more and more attention has been paid to the corrosion protection of marine structural engineering. [0003] Coating technology is an important and effective method for marine structural engineering prot...

AI Technical Summary

Problems solved by technology

In the past, metal protective materials were used for corrosion protection coatings of marine concrete structures. Generally, chlorinated rubber, polyurethane, chlorosulfonated polyethylene and epoxy coatings were used, and their comprehensive properties could not meet the requirements of harsh marine environments to some extent.

In addition, conventional water-based coatings and special protective materials for concrete, such as permeable concrete protective materials and fiber-reinforced materials, still have problems such as high requirements for the construction environment, difficulty in forming effective surface protection structures, and difficult construction.
