preparation example Construction

[0021] The preparation method of anticorrosion coating for seawater pipeline of the present invention:

[0022] (1) Preparation of piezoluminescent material: Dissolve bromotetraphenylethylene and 4-formylphenylboronic acid in toluene, add tetrabutylammonium bromide and potassium carbonate aqueous solution; Phenylphosphine) palladium, heated to 90 ° C for 24 hours; after the reaction, the reaction solution cooled to room temperature was poured into water, and extracted with ethyl acetate; after the organic layer was dried with anhydrous sodium sulfate, the solvent was evaporated and used Silica gel column chromatography is purified, and the mixed solvent of n-hexane and methylene chloride is used as the eluent to leaching, and the white product obtained is the piezoluminescence material, and the output rate is 88%; because the coating of the present invention is generally used Natural light is relatively poor on seawater piping components. Therefore, in order to ensure the act...

Abstract

The invention belongs to the technical field of paint. The invention aims at providing anticorrosive paint for seawater pipelines. The anticorrosive paint has the advantages of safety, no toxin, highefficiency and durability. The anticorrosive paint for the seawater pipelines is characterized by being prepared from the following raw materials in parts by weight: 10 to 15 parts of a piezoluminescence material, 6 to 8 parts of a photocatalyst material, 45 to 50 parts of modified natural polysaccharide type super absorbent resin, 20 to 25 parts of zinc acrylate resin, 0.5 to 1 part of emulsion paraffin, 1 to 2 parts of PP fiber, 1 to 3 parts of phospholipid emulsifier, 4 to 6 parts of organic bentonite and 2 to 3 parts of propylene glycol. The anticorrosive paint disclosed by the invention has the advantages of environmental friendliness, safety, long-lasting effectiveness, and ability in effectively preventing microbial attachment.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-corrosion coating for seawater pipelines and a preparation method thereof. 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 addition to the corrosion of seawater, the corrosion of microorganisms and fungi is also an important part of it. To solve the above problems in the prior art, toxic preservatives are generally added to the paint. Although a certain anti-corrosion effect has been obtained, it has also caused great damage to the marine ecological environment, especially the water environment around seawater pipelines. Contents of the invention [0003] The purpose of the present invention is to provide a safe, non-toxic, efficient and durable anticorrosion coating for seawater pipelines. [0004] In order to achieve the a...
