Problems solved by technology

Due to the low hardness and poor wear resistance of traditional metal surface anti-corrosion coatings, the coating is easy to be scratched and damaged; the toughness is poor, and the coating is prone to cracking and peeling; the weather resistance is poor, and cracking and discoloration are prone to occur after a period of use; the preparation method is complicated , higher construction requirements
Therefore, the comprehensive anti-corrosion performance is average, and it cannot effectively protect the metal substrate for a long time.

Abstract

The invention discloses a hydrophobic anti-corrosion ceramic coating, which uses epoxy resin and modified silicone resin as a film-forming material, and adds various fillers, auxiliary agents and solvents, including body fillers, pigments and fillers, curing agents, coloring Agent, toughener, diluent, leveling agent, epoxy coupling agent and solvent. The hydrophobic anti-corrosion ceramic coating of the present invention has stable performance, strong adhesion, excellent salt water resistance, strong acid and alkali corrosion resistance, good weather resistance, high hardness, and excellent wear resistance; and it is environmentally friendly and non-toxic (low VOC), and has Good protection, decoration and functional effects, low price of raw materials, simple preparation method, suitable for the surface of metal substrates that need to be protected under harsh corrosion environments.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a hydrophobic anti-corrosion ceramic coating and a preparation method thereof. Background technique [0002] The phenomenon of metal corrosion widely exists in people's production practice and life. A large amount of metal materials are lost due to corrosion every year in the world, and the harm caused by it cannot be underestimated. At present, there are many methods for anti-corrosion of metal surfaces, but the most widely used, most economical and practical method is surface anti-corrosion coating. In the face of increasingly harsh corrosive environments, anti-corrosion coatings are also playing an increasingly important role. Due to the low hardness and poor wear resistance of traditional metal surface anti-corrosion coatings, the coating is easy to be scratched and damaged; the toughness is poor, and the coating is prone to cracking and peeling; the weather res...
