Embodiment 1

[0033] 1) Add 30 parts of degradable polyurethane resin with broken main chain, 20 parts of cuprous oxide and 5 parts of SeaNine-211 antifouling agent into a metal tank with a sealed cover. Shake at / min for 10 minutes, and at the same time pass condensed water through the metal tank to cool down to ensure that the temperature is not higher than 50°C;

[0034] 2) Add 4 parts of white vaseline, 1 part of bentonite, 15 parts of zinc oxide, 15 parts of talcum powder, and 10 parts of xylene into the metal tank in turn, vibrate for 2 hours at a speed of 3000r / min on the paint rapid disperser, and cool down with condensed water , to ensure that the reaction temperature is not higher than 50°C;

[0035] 3) Use a scraper fineness meter to detect the fineness of the paint, and when the fineness of the paint reaches below 50 microns, the required antifouling paint can be obtained.

[0036] The prepared antifouling paint is evenly coated on the surface of the hanging board to form an an...

Abstract

The invention discloses an antifouling paint which comprises the following components in parts by weight: 20-40 parts of main chain fracture type degradable polyurethane resin, 20-40 parts of cuprous oxide, 20-30 parts of a pigment filler, 5-15 parts of an auxiliary anti-pollution auxiliary, 2-5 parts of an auxiliary and 10-20 parts of an organic solvent. Compared with the prior art, the antifouling paint has the advantages of good antifouling effect, long release time, environmental friendliness and the like. In addition, the invention further discloses a preparation method of the antifouling paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to an antifouling coating and a preparation method thereof. Background technique [0002] Biofouling is a natural phenomenon in which marine fouling organisms attach to man-made equipment and adversely affect the operation and safety of the equipment. With the development and utilization of marine resources and energy, more and more marine engineering equipment is operating in the underwater environment of the ocean. Biofouling has become a difficult problem for human beings to conquer the ocean. Effective and safe prevention of marine biofouling has become a research hotspot. [0003] The attachment of sea organisms to marine structures of Binhai nuclear power plant will have some adverse effects, especially for nuclear power plants with long-distance water delivery tunnels, the attachment of sea organisms will increase plant power consumption, redu...
