preparation example Construction

[0022] The preparation method of the piezoluminescent material of the present invention is as follows: dissolve bromotriphenylethylene and 4-formylphenylboronic acid in toluene, add tetrabutylammonium bromide and potassium carbonate aqueous solution; (Triphenylphosphine)palladium, heated to 90°C for 24h; after the reaction, pour the reaction solution cooled to room temperature into water, and extract with ethyl acetate; after the organic layer was dried with anhydrous sodium sulfate, the solvent was evaporated , using silica gel column chromatography for purification, using n-hexane and dichloromethane mixed solvent as the eluent to leaching, the obtained white product is the piezoluminescence material, and the yield is 97%.

[0023] The general structural formula of the piezoluminescence material is:

[0024]

Embodiment 1

[0026] 1) Preparation of anti-fouling and anti-corrosion enhanced emulsion:

[0027] Take by weight 30 parts of piezoluminescent material, 10 parts of photocatalyst material and 40 parts of acrylic zinc resin; under the rotating speed of 300 rpm, add piezoluminescent material, photocatalyst material and acrylic zinc resin together in the mixer, stir Preliminary mixing for 5 minutes; then adjust the rotation speed to above 1200 rpm, and stir for 10 minutes to obtain an antifouling and anticorrosion enhanced emulsion;

Abstract

The invention belongs to the technical field of coatings, and aims at providing a preparation method of a marine antifouling and anticorrosive coating. The technical scheme is characterized in that the preparation method of the marine antifouling and anticorrosive coating comprises the following steps: 1), preparing antifouling and anticorrosive strengthening emulsion; 2), preparing an environmentally-friendly antifouling and anticorrosive coating; 3), mixing the antifouling and anticorrosive strengthening emulsion with the environmentally-friendly antifouling and anticorrosive coating. The marine antifouling and anticorrosive coating is safe, environmentally-friendly and long-lasting in effect and can effectively prevent microbial attachment.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a preparation method of marine antifouling and anticorrosion coatings. Background technique [0002] Marine corrosion refers to the corrosion of metal components in the marine environment. The marine environment is a complex corrosive environment. In this environment, seawater itself is a strong corrosive medium. At the same time, waves, waves, tides, and currents produce low-frequency reciprocating forces and impacts on metal components, plus marine microorganisms, attached organisms, and their metabolites. All of them have a direct or indirect acceleration effect on the corrosion process. Among the technologies that have been developed to prevent marine organisms from attaching and growing, antifouling coatings have developed the fastest and are most widely used in recent years because of their economical, effective and easy-to-operate advantages. Antifouling coa...
