What is zinc stearate emulsion?
Zinc stearate is an organic substance with a chemical formula of C36H70O4Zn. It is a white powder and is insoluble in water. Mainly used as lubricant and release agent for styrene resin, phenolic resin, and amino resin. At the same time, it also has the function of vulcanization activator and softener in rubber.
The aqueous emulsion of zinc stearate is called zinc stearate emulsion . It has a wide range of applications and can be used as a release agent, color retention agent, lubricant, release agent, etc.
Z inc stearate emulsion Characteristics
Insoluble in water, soluble in hot organic solvents such as ethanol, benzene, toluene, turpentine, etc. ; decomposes into stearic acid and corresponding salts when encountered with acid; fire hazard under dry conditions, spontaneous ignition point 900; hygroscopic
Z inc stearate preparation
There are two production methods of zinc stearate: the water method and the melting method.
Generally speaking, zinc stearate produced by the water method is acidic, and the melting method is alkaline. The water method is also called the wet method. Under the condition of the water as the medium, a catalyst is added to control a certain temperature and pressure, and then a metal hydroxide is added. The metal ions are replaced by the catalyst through the catalyst and then replaced by the catalyst itself to stearin. Acid, so as to achieve the purpose of generating metal salts. The catalyst undergoes post-processing and is recycled. The stearate is centrifuged, dried, and ground to obtain a product with a mesh number of 200-600 that meets industry standards. Water production usually has a slight excess of stearic acid, so the finished product appears acidic after the reaction.
The melting method is also called the dry method, which means that the metal oxide (indirect method zinc oxide) is directly added to the molten stearic acid (of course, under the presence of a catalyst, otherwise the conversion rate of the reaction will be very long and very long) Control a certain temperature, pressure and stirring speed to obtain stearate through reaction. The products produced by the dry method can be completely reacted due to the presence of the catalyst in general reaction results, and the metal oxides are slightly excessive, so the product is alkaline when tested.
Use of zinc stearate emulsion
Zinc stearate can be used as a heat stabilizer; lubricant; grease; accelerator; thickener, etc. For example, it can generally be used as a heat stabilizer for PVC resin. Used in general industrial transparent products; used with a calcium soap, can be used in non-toxic products, generally, this product is mostly used in soft products, but in recent years, hard and transparent products such as mineral water bottles, water pipes, and other products have been used. This product has good lubricity and can be used. It can improve the appearance of fouling, and can also be used as a lubricant, a release agent, a flattening agent for paints, and an additive for paints.
Zinc stearate emulsion has a wide range of applications, including rubber, plastics, coatings, inks, paints, thermal paper, cosmetics, and other industries.
Rubber industry: release agent, release agent, active agent, etc.
Plastic industry: internal release agent
Coating industry: color retention agent, filler, etc.
Paint industry: grinding aids
