Technical Field

The invention belongs to the technical field of coatings, and particularly relates to a water-based ship biological antifouling industrial coating and a preparation method thereof.

Background

Coating materials, also called paints, are continuous films which are applied to the surface of objects to be protected or decorated and which form a firm bond with the object to be coated, and are generally viscous liquids based on resins, oils or emulsions, with or without pigments, fillers, and with the addition of corresponding auxiliaries, formulated with organic solvents or water.

There are more than 2000 kinds of attached organisms in sea areas around the world, and larvae and spores of the attached organisms float in the ocean and attach to the bottom of a ship, settle down and further reproduce when they develop to some extent. The organisms increase the fuel consumption and destroy the paint film at the bottom of the ship, and meanwhile, the organisms secrete organic acid, so that the destruction of the steel plate at the bottom of the ship and underwater facilities is aggravated, and the service life is obviously shortened. To solve this problem, various antifouling paints for ships have come into play.

The traditional antifouling paint is used for poisoning attached organisms through seepage of an antifouling agent to achieve the antifouling purpose, and the method can pollute the environment more or less, so people are trying to design and develop the antifouling paint from a new idea, on one hand, an antifouling high polymer material is searched to simulate the skin state of some organisms, and on the other hand, a proper natural biological antifouling agent is searched to prevent the organisms from attaching on the premise of not damaging the environment.

Disclosure of Invention

The invention aims to solve the technical problems and provides a water-based marine biological antifouling industrial coating and a preparation method thereof, which mainly solve the problems that the attached organisms are poisoned by the seepage of an antifouling agent to reduce the attachment amount of the organisms in the traditional antifouling coating and the like.

In order to achieve the purpose, the invention adopts the following technical scheme:

the raw material composition of the water-based marine biological antifouling industrial coating comprises, by weight, 25-60 parts of a film-forming substance, 5-50 parts of a biological antifouling agent, 1-20 parts of a pigment, 1-50 parts of a filler, 5-10 parts of an auxiliary agent and 10-30 parts of water.

The preparation method of the water-based marine biological antifouling industrial coating comprises the following steps:

s1, sequentially adding water and the auxiliary agent into a reaction cylinder, and stirring until the water and the auxiliary agent are completely dissolved to obtain a mixture A;

s2, adding the pigment and the filler into the mixture A in sequence while stirring, dispersing and grinding to reach the average fineness of 30-50 mu m to obtain a mixture B, and adjusting the rotation speed to 500 r/min;

Compared with the prior art, the invention has the beneficial effects that:

the water-based ship biological antifouling paint mainly comprises a biological antifouling agent and a film forming substance, and can form a uniform antifouling protective layer on the bottom surface of a ship. Wherein capsaicin [ trans ] 8-methyl-N-vanillyl-6-nonenamide ] in the biological antifouling agent is an active ingredient of pepper, capsaicin and compounds related to the capsaicin are called capsaicin, and are secondary metabolites produced by the pepper and form deterrents to herbivores, and pure capsaicin is a water-repellent lipophilic colorless odorless crystalline or waxy compound. The low-surface-energy non-toxic antifouling paint prepared by taking powdery capsaicin as a natural antifouling agent can resist the adhesion of bacteria and marine organisms and has good adhesion to metal, wood, cement and the like; the sodium benzoate in the biological antifouling agent is easy to dissolve in water, the solubility is about 53.0g/100ml at normal temperature, the lipophilicity of the sodium benzoate is larger, the sodium benzoate easily penetrates cell membranes to enter cell bodies, the permeability of the cell membranes is interfered, the absorption of the cell membranes to amino acid is inhibited, the sodium benzoate enters the cell bodies to ionize and acidify the alkali storage in the cells, the activity of a respiratory enzyme system of the cells is inhibited, and the condensation reaction of acetyl coenzyme A is prevented; tannic acid in the biological antifouling agent is a strong fixing agent which can fix a plurality of proteins and saccharide derivatives, and is a mordant which can enhance the absorption of heavy metals (such as uranium and lead) so as to enhance the contrast of samples, particularly cell outer membranes, elastic fibers, cell junctions, muscle fibers and the like. The sodium benzoate and tannic acid have anesthetic effect on larvae of crustacean and marine periphyton, do not kill the periphyton, and can be recovered only by placing in fresh seawater.
