Description
Technical Field
The invention relates to a high-wear-resistance moisture-proof coating composition, a preparation method and application thereof, in particular to a high-wear-resistance fluorine-containing polymer composite coating composition which is used for high-wear-resistance water-proof, moisture-proof and corrosion-resistant purposes between an electronic device and a connecting piece thereof.
Background
With the continuous development of electronic technology, the use of portable electronic products is more and more popular, and the use places and environments are more complicated and harsh, which puts higher demands on the waterproof, moisture-proof and corrosion-resistant properties of the portable electronic products. The use of a fluorine-based solvent solution of a fluorine-containing alkyl acrylate polymer as a coating agent has attracted much attention because it can form a water-and moisture-repellent coating of 1 μm or less on an electronic device. However, the existing fluorine-based waterproof and moistureproof coating agent has low wear resistance, and touches or rubs the protective coating in the production, assembly or use process of consumers, so that the waterproof and moistureproof performance of the coating is reduced and the protective performance is lost.
Patent (CN 104220541) discloses a silicon-containing fluoroalkyl acrylate polymer obtained by radical polymerization of fluoroalkyl acrylate and alkoxysilyl group-containing radical polymerizable monomer, and the coating prepared therefrom shows better abrasion resistance. But the wear resistance still can not meet the requirements of some scenes.
The patent (CN 106833166) discloses a waterproof fluorinated liquid, which is composed of fluorocarbon resin, hydrofluoroether, perfluoroalkyl acrylate, carbon-hexa waterproof agent, nonionic fluorocarbon leveling agent, organic silicon, isocyanate, hydroxyethyl cellulose and water, wherein the waterproof agent is coated on a PCB substrate and is cured to form a transparent waterproof coating. The patent (CN 106555336) discloses a fluorine-containing water-repellent and oil-repellent finishing agent and a preparation method thereof, wherein a perfluoro monomer, an emulsifier, an organic solvent and water are emulsified, and then a vinyl monomer and an initiator are added for polymerization reaction to obtain a product. However, water is used as a solvent additive in the preparation process of the fluorine-containing moisture-proof agent, and the fluorine-containing moisture-proof agent cannot be directly used for spraying electronic elements, so that the application of the prepared moisture-proof agent in the aspects of water resistance and moisture resistance of electronic products is limited.
