Problems solved by technology

[0002] Compositions containing water, such as most liquid cleaners, water-based paints, printing fountain solutions, etc., are susceptible to microbial spoilage due to the presence of water, which not only impairs the performance of the product but, in extreme cases, Users cause health hazards. Therefore, in order to protect the service life of the product, fungicides are generally added during the product manufacturing process. At present, most of the solvent additives in the existing fungicides use alcohols, potassium hydroxide and hydroxide The price of sodium and alcohol solvents is relatively high, which will increase the cost of fungicides, and potassium hydroxide and sodium hydroxide solvents, in winter, potassium hydroxide and sodium hydroxide in fungicides will crystallize due to the drop in temperature , leading to a decrease in the bactericidal performance of the fungicide
