Usage
Copper naphthenate (abbreviated as CuN), also known as copper naphthoate and copper petrolic acid, has a molecular formula of (C10H19COO)2Cu. It is a complex of alkylphenol polyoxyethylene ether. It can be dissolved in water of any hardness, is resistant to acids and alkalis, and has excellent properties such as emulsification, leveling, wetting and diffusion. It can be mixed with various types of surfactants and dye resin prepolymers. Copper oxide or copper carbonate is co-dissolved with naphthenic acid, or copper naphthenate is prepared by double decomposition reaction of soluble copper salt and sodium naphthenate. Commercial copper naphthenate contains 6% to 8% copper. It is a dark green viscous substance, insoluble in water but soluble in petroleum solvents. It has a special musty smell and is very low in toxicity to humans and animals. Its chemical properties are relatively stable. It is a high-efficiency, low-toxicity and environmentally friendly wood preservative. In recent years, it has received special attention. It is mainly used for the preservation of joinery, horticultural and shipbuilding materials. It has a strong ability to prevent damage from marine boring animals. As an exuding additive in antifouling paint, it is used in ship antifouling paint, which can play the effect of toughening the paint film and increasing the exudation rate of antifouling agents. To achieve the purpose of regulating and controlling the exudation of antifouling agents. Recommended dosage: 0.05-0.2% (metal to resin solid content). It can also be used as an anticorrosive and mildew preventive agent for cables, fabrics and leathers. Recently, water-borne copper naphthenate has been developed, using organic amines as solvents, which creates conditions for the popularization and application of copper naphthenate.
