What is zinc stearate? Property ofzinc stearate: white, fine powder, greasy, slightly pungent odor. Density (g/mL, 25/4 ℃): 1.0953. Melting point (℃): 130, self-ignition point (℃) 900. Solubility: insoluble in water, alcohol, and ether. Soluble in benzene, turpentine, and other organic solvents. It can be used as a non-toxic polyvinyl chloride stabilizer with low initial coloration and good weather resistance. It is not easy to use alone because it has a significant catalytic effect on the degradation of PVC. After some time, It can make the product change color rapidly. It can be used with barium cadmium soap for general soft products. The dosage of this product is not easy to be too large, but it can be appropriately increased when used with epoxy compounds and phosphorous esters.
Synthesis of zinc stearate (1) Preparation of sodium stearate solution Dissolve stearic acid in 20 times (mass) of hot water, add 1074 kg/m3 (10 ° B é) of caustic soda solution, and saponify at about 75 ℃ to produce a dilute sodium stearate solution (2) Add 1074 kg/m3 (10 ° B é) of zinc sulfate aqueous solution to the sodium stearate solution prepared above, and carry out the double decomposition reaction at about 60 ℃. The product zinc stearate is precipitated. Then, it is filtered, washed, and dried at about 90 ℃ to obtain the finished product (3) Dissolve 15g of sodium stearate in 1L of hot water and add it to the excess zinc chloride solution with a concentration of 1% while it is hot. Stir it fully to separate the solid zinc stearate soap, then wash it with water by pouring it until there is no zinc salt. Dry it in an air bath at 115~120 ℃ for 10~12h to obtain a flaky zinc stearate product. Crush it and store it in a sealed glass bottle.
Use of zinc stearate 1. It can be used as a non-toxic stabilizer for PVC, with low initial coloration and good weather resistance. This product is not easy to use alone because it has a significant catalytic effect on the degradation of PVC. After some time, it can cause sharp discoloration of the product. It can be used with barium cadmium soap for general soft products. The amount of this product is not easy to be too large, but it can be appropriately increased when used with epoxy compounds and phosphorous esters 2. It can also be a lubricant for styrene resins, including polystyrene, ABS, and SAN resins, and a release agent for transparent products. This product can be used in the rubber industry as a lubricant and a diaphragm agent (anti-sticking) for rubber materials. In addition, it can also be used as a textile polishing agent, a paint leveling agent, and a cosmetic ingredient.
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.
