The invention discloses a preparation method of nano-organic metal carboxylate. The invention effectively solves the problems of complicated water washing process, complicated preparation of lye, dangerous and uneconomical in the traditional production process of metal organic carboxylate, and proposes a A new technology for preparing high-quality organometallic carboxylate by using carboxylic acid, caustic soda, metal oxide or hydroxide as raw material and assisted by ball milling method. In addition to the efficient use of liquid caustic soda, the present invention can also obtain high-quality organometallic carboxylate, overcomes the technical prejudice that the prior art uses salts such as calcium chloride and sodium chloride for poor reaction efficiency, and fundamentally solves the problem. The problem of environmental pollution caused by the washing waste liquid in the existing process. At the same time, the addition of nonionic surfactants makes ball milling more efficient and significantly reduces product particle size. The present invention can bring better environmental protection benefits and economic benefits. |
