Overview of Zinc Stearate

Zinc stearate is an organic substance with the chemical formula C36H70O4Zn, which is a white powder and insoluble in water. Mainly used as lubricant and mold release agent for styrene resin, phenolic resin and amine resin. At the same time, it also has the functions of vulcanization active agent and softener in rubber.

Zinc stearate production method

There are two production methods for zinc stearate: water method and melt method. Generally speaking, zinc stearate produced by water method is acidic, and molten method is alkaline.

The water method is also called the wet method. Under the condition of water as the medium, a catalyst is added, a certain temperature and pressure are controlled, and then a metal hydroxide is added, and the metal ions are replaced on the catalyst through the catalyst, and then replaced by the stearin through the catalyst itself. acid, so as to achieve the purpose of generating metal salts. The catalyst undergoes subsequent treatment and is recycled. The stearate is centrifuged, dried and ground to obtain a product with a mesh number of 200-600 that meets the industry standard. In water production, stearic acid is usually slightly excessive, so the finished product is acidic after the reaction.

The melting method, also known as the dry method, refers to the direct addition of metal oxides (zinc oxide) to the molten stearic acid. The temperature, pressure and stirring speed can be obtained through the reaction to obtain stearate. Due to the presence of catalyst, the product produced by the dry method can generally be completely reacted, and the metal oxide is slightly excessive, so the product is alkaline when detected.

Application of Zinc Stearate Emulsion

Zinc stearate emulsion can be used as heat stabilizer; lubricant; grease; promoter; thickener. For example, it is generally used as a heat stabilizer for PVC resins. For general industrial transparent products; can be used with calcium soaps. Can be used for non-toxic products.

Zinc stearate is commonly used as a mold release agent, heat stabilizer and lubricant in the plastics, polyolefins, polystyrene and rubber industries. Zinc stearate is also used as a polishing additive in wood coatings (lacquers). In cosmetics, zinc stearate is a lubricant and thickener that improves texture. Zinc stearate emulsion is widely used, including rubber, plastic, paint, ink, paint, thermal paper, cosmetics and other industries.
