Dimethyl silicone polymer marine antifouling paint containing sodium benzoate

Abstract

The invention discloses a dimethyl silicone polymer marine antifouling paint containing sodium benzoate, which relates to an antifouling paint containing the sodium benzoate, wherein the sodium benzoate is needed to be added into a dimethyl silicone polymer silicone resin matrix to prepare the antifouling paint. The dimethyl silicone polymer marine antifouling paint adopts the sodium benzoate, a dimethyl silicone polymer silicone resin, an organic solvent, deionized water and a curing agent, and is characterized by being prepared through the following steps: firstly, according to the mass percentage of the sodium benzoate in the dimethyl silicone polymer silicone resin, adding the sodium benzoate in the mass ratio of 10 percent into the deionized water, and performing magnetic stirring onthe mixture for 3 hours; secondly, gradually dropping the organic solvent of acetone, methylbenzene or acetonitrile into the mixture in the ratio of the organic solvent to the water of 3:5, continuously stirring the mixture for 3 hours, and performing ultrasonic vibration on the mixture for 1 hour; thirdly, slowly adding the obtained mixed solution into dimethyl silicone polymer, and placing the mixture which is stirred evenly through magnetic stirring into a ventilating cabinet for two days for volatilizing the organic solvent; and finally, adding the dimethyl silicone polymer curing agent into the mixture in the ratio of 1:10, and evenly mixing the mixture.

Description

technical field [0001] The present invention relates to polydimethylsiloxane marine antifouling paint containing sodium benzoate. Background technique [0002] The antifouling coatings originally used on ships mainly use toxic release antifouling as the main technical method. Through the releasable copper, tin, mercury, lead and other heavy metal antifouling agents in the coating, marine plant spores and spores are formed around the material. Marine animal larvae have a toxic material concentration layer that kills them, so as to achieve the antifouling effect. However, the poisonous antifouling agents of this type are very serious. Even a few parts per ten billion of organic tin is enough to deform some marine organisms, inhibit their reproduction, and is not suitable for consumption. After the 1970s, with the prohibition of antifouling agents such as mercury and arsenic, organotin compounds became representative antifouling agents. In the 1980s, it was discovered that or...
