Embodiment 1

[0016] Weigh 15 kg of acrylate emulsion (model DC-W10, purchased from Beijing Dechang Weiye Construction Engineering Technology Co., Ltd.), 6 kg of 5-(4-hydroxybenzyl)thiazolidine-2,4-dione, iron red 2 kg, 3 kg of EFKA 6745, 2 kg of BD-3032, 2 kg of talcum powder, 2 kg of hydroxyethyl cellulose and 80 kg of water, fully stirred and mixed at 250r / min for 30 minutes, poured into a conical mill for grinding , to obtain a pigment slurry, weigh 1.5 kg of Dow Corning DC-65 additive and 3 kg of alcohol ester-12, slowly add to the pigment slurry under low-speed stirring 200r / min, stir for 30min, filter, and discharge to obtain.

Embodiment 2

[0018] A water-based antifouling paint was prepared in the same manner as in Example 1, except that 5-(4-hydroxybenzyl)thiazolidine-2,4-dione was not used.

experiment example

[0020] A low-carbon steel plate of 150×70×2mm was used as the bottom plate of the sample. After grinding and derusting, acetone degreasing. The paint prepared in the examples was painted on it to form an antifouling coating. Using the SL200D contact angle tester of Shanghai Solon Information Technology Co., Ltd., the contact angle of the antifouling coating was tested by the pendant drop method (sea water). The results show that the contact angle of the antifouling coating in Example 1 can reach 163°, while that of the antifouling coating in Example 2 is only 103°, and there is a significant difference between the two (P<0.05). The larger the contact angle is, the stronger the antifouling property is, thus it can be seen that the coating of the present invention has stronger antifouling property.

Abstract

The invention relates to use of 5-(4-hydroxy phenylmethyl) thiazolidin-2,4-dione serving as an anti-fouling agent in an aqueous coating material. The aqueous anti-fouling coating material disclosed by the invention has a relatively good anti-fouling effect and has broad prospects in industrial application.

Description

technical field [0001] The invention relates to the field of coatings, in particular, the invention relates to an antifouling agent for water-based coatings. Background technique [0002] With the development of human industry, the application of antifouling technology has become increasingly widespread. Among all antifouling technologies used by human beings, the use of antifouling coatings is the most mature, economical and widely used method. Organotin self-polishing antifouling coatings developed in the 1970s have been widely used due to their high efficiency and spectral properties. However, subsequent studies have shown that organotins are harmful to ecology and human health. Traditional coatings use organic solvents as solvents, which will release volatile organic gases (VOC), pollute the environment and harm the health of workers. Therefore, the development of high-efficiency, low-toxicity, non-toxic, water-based antifouling coatings has become an inevitable devel...
