Environment-friendly nano antifouling algicide and preparation method thereof

Abstract

The embodiment of the invention discloses an environment-friendly nano antifouling algicide and a preparation method thereof. The environment-friendly nano antifouling algicide is prepared from the following raw materials by mass percent: 5 to 10 percent of water-based nano silver dispersoid size, 10 to 20 percent of 4,5-dichloro-N-octyl-4-isothiazoline-3-one, 5 to 10 percent of 2-octyl-4-isothiazoline-3-one, 5 to 10 percent of benzimidazole, 3 to 5 percent of emulsifier, 5 to 8 percent of antifreeze, 1 to 3 percent of penetrant, 1 to 3 percent of amine neutralizer, 1 to 3 percent of thickener, 5 to 10 percent of solubilizing stabilizer, 5 to 10 percent of synergist, 5 to 8 percent of ethanol and 20 to 30 percent of deionized water. The environment-friendly nano antifouling algicide and the preparation method thereof disclosed by the invention have the characteristics of low manufacturing cost, low toxicity, safety for water source and environment, and are of great significance for saving energy, protecting the environment and creating a harmonious relationship between human and nature.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of functional fine chemical materials, specifically a degradable and environmentally friendly nano-scale antifouling and algae-removing agent that can be widely used in industrial fields and a preparation method thereof. Background technique [0002] For many years, the problem of marine biofouling has plagued human development and application of the ocean, and the prevention and control of marine biofouling has also become a worldwide problem and research hotspot. Ships, warships, submarines and other underwater vehicles are submerged in seawater for a long time. Not only are they corroded by seawater, but their surfaces are also prone to adhere to marine organisms and are fouled by marine deposits. On the one hand, it increases the weight and frictional resistance of the hull, increases fuel consumption, and if there is data on the surface, biofouling can lead to an increase in fu...

Problems solved by technology

[0007] At present, traditional antifouling and algicides still have many disadvantages, such as high cost, harmful and toxic volatile substances such as VOC, aromatic hydrocarbons, and heavy metals, which seriously pollute the environment and water sources, and the antifouling methods of certain varieties are single and static. Poor antifouling performance, short antifouling period, poor broad spectrum, unsatisfactory physical properties, etc.
