Calcium stearate is an organic compound with the molecular formula of C36H70CaO4, which is a white powder and insoluble in water. It can be used as a waterproofing agent, lubricant, and plastic additive.
Manufacturing method of Calcium Stearate Powder 1. Synthesis of calcium stearate. Calcium chloride solution with the content of 1074 kg/m3 was added to the sodium stearate solution prepared above, and the double decomposition reaction was carried out at about 65℃, and the product calcium stearate was precipitated. And then filtering, washing with water, and drying at about 90 DEG C to obtain the finished product. 2. Suspend 5.60g(0.1mol) of calcium oxide in 300ml of hot water at 55℃. Then, 51.3g of chemically pure stearic acid was dissolved in 350 ml of hot water at 70℃, and then 0.75g of diethanolamine was added and stirred to emulsify it. Gradually add the prepared stearic acid emulsion into calcium oxide suspension within two h, and fully stir, filter out the formed white insoluble substance, namely calcium stearate, and dry to obtain the product. 3.By the direct method, a certain amount of stearic acid and CaO are added into a reaction kettle equipped with a stirrer and a thermometer, the temperature is raised to melt, the catalyst H2O2 is slowly added under constant stirring, and the vacuum is pumped, and the reaction temperature is controlled at 140-150℃ for 1.5-2.0h. After the reaction, discharging, cooling, and crushing to obtain the product. 4. Double decomposition method: dissolve stearic acid in 20 times hot water, add saturated caustic soda solution, and saponify at about 75℃ to generate a dilute sodium stearate solution. Then, the calcium chloride solution with a content of 1074kg/m3 was added into the sodium stearate solution, the double decomposition reaction was carried out at about 65℃, and the product calcium stearate was precipitated. And then filtering, washing with water, and drying at about 90 DEG C to obtain the finished product. Uses of Calcium Stearate Powder Used as heat stabilizer of PVC, lubricant, and release agent for various plastics processing, etc. In hard products, the gelation rate can be increased when it is combined with basic lead salt and lead soap. It is also used for soft films and appliances that require no toxicity, such as food packaging and medical appliances. As a plasticizer in rubber processing, it can soften natural rubber and whole rubber but has almost no effect on vulcanization. It is also used as a lubricant for polyolefin fiber and molding compound, a thickening agent for lubricating grease, a waterproofing agent for textiles, a flatting agent for paints, a plasticizer for making plastic records, etc. In addition, it is used as a halogen absorbent in polyethylene and polypropylene; a Lubricant and release agent for thermosetting plastics such as phenolic and amino; a Thickener of lubricating grease; a Waterproof agent for waterproof fabric; a Flattening agent for paint and lubricant for pencil lead, etc. Food grade calcium stearate is used as an anti-caking agent. Calcium stearate is also used in pencil lead production, medicine, and the spice industry.
