Abstract

The invention discloses a rusty paint using inorganic substances as the carrier of organic functional molecules. The carrier material is an inorganic carrier and has a material combined with organic molecules, including but not limited to nanoporous materials, inorganic molecular sieve materials, silicic acid Salt, wherein the pore size of the inorganic molecular sieve is not less than 100nm; the organic functional material refers to an organic molecular material that can combine with rust and inhibit rust corrosion; specifically, one side of the molecular material can be combined with the rust layer, and the other side can be combined with the organic Material combination; the present invention can flexibly design functional molecules according to the selected resin; the reaction is simple, no catalyst is needed, and the required compound can be obtained only by changing the synthesis temperature according to the difference in the functional groups connected in the molecular structure, and the side effects of the reaction The product also does not affect its performance.

Description

technical field [0001] The invention relates to the technical field of rusty coatings for coatings, specifically, a coating containing repairing materials is used to repair failed coatings, specifically the function of loading the repairing materials on molecular sieves and releasing them under appropriate conditions coating. Background technique [0002] With the increase of large-scale metal facilities, the protective coating of large-scale infrastructure has become a problem that needs to be solved. After the general coating is painted on the rusted coating, it will return to rust due to the corrosiveness of the rust. Therefore, the general The coating does not have the ability to be repaired by painting on the old coating, which requires the repair coating to have a low surface, inhibit rust and corrosion, improve the surface function between the old and new coatings, and increase the bonding force of the old and new surfaces. The film-forming substance does not have th...
