Preparation method of self-repairing fluorocarbon coating for ships

Abstract

The invention relates to the technical field of coating preparation and in particular relates to a preparation method of self-repairing fluorocarbon coating for ships. The self-repairing fluorocarboncoating for the ships is prepared by taking a self-made oil-soluble capsule core and a sodium dodecyl benzene sulfonate solution as raw materials, emulsifying and dispersing to obtain oil-in-water emulsion, doping a self-made urea formaldehyde pre-polymer into the oil-in-water emulsion, treating to obtain a microcapsule, mixing and stirring a self-made co-solvent, PVDF (Polyvinylidene Fluoride) fluorocarbon resin and titanium white powder to obtain a pre-dispersed raw material and finally, stirring the pre-dispersed material, a self-made carbon nanotube dispersion solution and the microcapsuleat a high speed, and stirring and curing at a low speed; tourmaline powder is adsorbed on a rough surface of the microcapsule and can be used for preventing marine organisms, such as shells and alga,from being attached on ship bodies to grow; meanwhile, the salt spray resistance performance of the fluorocarbon coating is improved; carbon nanotubes are doped so that the siphon action generated bycracks can be enhanced; the capsule core in the microcapsule is slowly released so that the cracks of a coating layer are completely repaired at a relatively rapid speed and the self-repairing fluorocarbon coating has a wide application prospect.

Description

technical field

[0001] The invention relates to the technical field of coating preparation, in particular to a preparation method of a self-repairing fluorocarbon coating for ships. Background technique

[0002] Now our country is in a period of rapid urbanization and industrialization, with a total construction volume of about 2 billion square meters per year. With the development of real estate and architectural decoration industry, the building decoration material industry has also developed rapidly, especially the use of exterior wall paint has increased year by year, and the use of fluorocarbon paint has also increased year by year.

[0003] Fluorocarbon coatings are film-forming substances based on fluorine-containing copolymer resins or fluoroolefin copolymers, which are processed, modified and ground. They are also called fluorocarbon paints, fluorine coatings, and fluororesin coatings. Among all kinds of coatings, fluororesin coatings have particularly superior pro...
