Abstract

The invention relates to an anticorrosive material. The material is prepared from the following raw materials in parts by weight: 50 to 80 parts of an isocyanate-terminated polyurethane prepolymer, 2 to 5 parts of aminopropyltriethoxysilane, 3 to 5 parts of filler, 3 to 5 parts of fly ash, 15 to 28 parts of zinc powder, 3 to 5 parts of modified tin dioxide, 3 to 5 parts of a carbon nanotube material, 10 to 30 parts of water, 5 to 6 parts of anticorrosive microcapsules and 0.5 to 2 parts of amino trimethylene phosphonic acid. According to the invention, the anticorrosive microcapsules are added into the anticorrosive material, so that the anticorrosive material has certain self-repairing performance, when the anticorrosive material generates cracks under the action of external force, the microcapsules are broken and release linseed oil and tung oil in the microcapsules, and the linseed oil and tung oil have a repairing effect on the cracks, so that the self-repairing effect on an anticorrosive coating is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to an anti-corrosion material and a production process thereof. Background technique [0002] Anti-corrosion material, that is, a material that inhibits chemical corrosion and electrochemical corrosion of the anti-corrosion object through this material, is widely used in many fields such as marine, energy, construction, transportation, aerospace, and military equipment. Among all anti-corrosion measures, organic coatings are the most widely used. Organic coatings isolate the metal substrate from corrosive media such as moisture, oxygen, and ions through physical shielding, thereby preventing the occurrence of electrochemical corrosion reactions. However, during the service and transportation of equipment, the coating will inevitably be damaged and cracked. If it is not repaired in time, the protective effect of the coating on the metal substrate will be reduced. At...
