Copper pyrithione (CPT) is a broad-spectrum, low-toxicity and environmentally friendly antibacterial and bacteriostatic agent, which is widely used in civil coatings, adhesives, carpets and other fields; It can also be used as a ship antifouling paint to prevent crustaceans, seaweed, and aquatic organisms from attaching to the ship's hull. Due to the low toxicity and stability of CPT, it can be added to the coating so that the coating exhibits gel stability and prolongs the storage time of the coating. Copper thiorione was prepared by the reaction of slightly soluble alkaline copper salt with thithione-alkali metal salt, and the crystal size of the product was small, and the average particle size was not more than 5 μ m. In addition, the alkaline copper salt, which is the residue of impurities in thithione copper products, is mixed with the antifouling coating on the bottom of the ship, which is the cause of the gelation of the coating during storage. CPT and its similar products have great application potential and broad application prospects in the field of pesticides due to their low toxicity and excellent broad-spectrum performance.
