Why zinc stearate can be used as a lubricant for glue?
What is zinc stearate?
Zinc stearate, also known as "zinc stearate", is a white fine powder with a melting point of 118 ℃~125 ℃ and a relative density of 1.095. It has a special smell. It is insoluble in water, and soluble in hot ethanol, benzene, toluene, turpentine, and other organic solvents. It is heated and dissolved in organic solvents, and then cooled to form a colloidal substance. It decomposes into stearic acid and corresponding zinc salt when meeting strong acids. It has a fire hazard under dry conditions, and its self-ignition point is 900 ℃, The minimum explosion limit of its dust and air mixture is 11.6 g/m3. It is hygroscopic and non-toxic and can be used for products in contact with food, with a toxicity coefficient of T=1000. It is generally a mixture of zinc stearate and zinc palmitate, and usually contains a slightly excessive amount of zinc oxide (13.5%~15%). It can be used as a stabilizer for PVC plastics, a reinforcing agent for styrene plastics, phenolic plastics, and amino plastics, a drying agent for paints, and coatings, a leveling agent for enamel, a drying agent, and a sanding agent, a Textile polishing agent, plastic molding release agent, waterproof agent, emollient in cosmetics, and pharmaceutical powder, tablet, ointment, etc.
Action principle of zinc stearate
It is found that during the manufacturing process of the master batch, the screw current will drop a lot after adding zinc stearate, and the mesh pressure will also drop. It feels that the material is smooth and has good fluidity. This is a layer of the lubricating film formed between the metal of the screw and the filter screen in the molten state of zinc stearate, and more importantly, zinc stearate can form a lubricating dispersion between the calcium powder and the plastic in the molten state, which is the same as the principle of hand soap.
Use of zinc stearate
Zinc stearate can be used as a lubricant of glue in the rubber industry, as a polishing agent in the textile industry, and as a cosmetic ingredient. In the production and processing of powder, it can also be used as an adhesive of powder to increase the adhesion of powder to the skin, and as a stabilizer of plastic products, playing a stabilizing role. In terms of dosage, there are usually different proportions according to the amount of solid, most of which are added by 50%.
Price of zinc stearate
Zinc stearate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of zinc stearate. A large amount of large amount will be lower. The price of zinc stearate can be found on our company's official website.
