A method for producing an oil wax barium soap, characterized by comprising steps of preparing raw materials, preparing an oxidized wax paste, saponification, water washing, and blending. Compared to existing technologies, this invention uses wax paste as the raw material and adds a small amount of oxidized wax paste as an initiator, which improves the adhesion performance of the product, making it less likely to fall off after use and providing the intended protective effect. It features a shorter oxidation time, lower energy consumption, an appropriate final pH value, lower cost, and better rust prevention on the finished product.
