Embodiment 1
[0015] Embodiment 1, a kind of preparation method of improved zinc stearate, comprises the following steps:
[0016] (1) Take raw materials according to the mass ratio of stearic acid, zinc oxide, catalyst and deionized water as 80:10:6:4, the purity of zinc oxide is more than 99.6%;
[0017] (2) Put stearic acid and deionized water into the reactor under normal pressure and heat to 70-95°C, then add zinc oxide to react for 0.5 hour, and the reaction temperature is 75-105°C;
[0018] (3) Add catalyst to the reaction kettle and stir the raw materials in the reaction kettle at a high speed. The temperature is maintained at 95-155°C throughout the process, and the stirring time is 0.8-1.5 hours. After cooling, the material is discharged to obtain zinc stearate.

Abstract
The invention discloses a preparation method of modified zincstearate. The method is characterized in that the method comprises the following steps: 1, taking raw materials according to a mass ratio of zincstearate to a zinc compound to a catalyst to deionized water of 80:10:6:4; 2, adding zinc stearate and deionized water to a reaction kettle under normal pressure, heating to 70-95DEG C, adding the zinc compound, and reacting at a temperature of 75-105DEG C for 0.5h; and 3, adding the catalyst to the reaction kettle, carrying out high speed stirring on the raw materials in the reaction kettle at a temperature of 95-155DEG C for 0.8-1.5h, cooling, and discharging to obtain zinc stearate. The preparation method of modified zinc stearate has the advantages of simple process, easy implementation, good product quality, reduction of the labor intensity of workers, improvement of the productivity and the economic benefit, reduction of the influence on the environment, and protection of the surrounding environment.
Description
technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a preparation method of an improved zinc stearate. Background technique [0002] Zinc stearate is mainly used as non-toxic stabilizer for polyvinyl chloride, lubricating release agent for plastic products, paint polishing aid, softener and release agent for rubber compound in the rubber industry, halogen absorber, textilewaterproofing agent and cosmetics Additives and tablet release agents have a wide range of markets at home and abroad. Especially with the strengthening of people's awareness of environmental protection and the introduction of relevant laws and regulations, zinc stearate and calcium stearate are important raw materials for calcium-zinc composite stabilizers. attention. [0003] The earliest production process of zinc stearate is metathesis method. The technical process is roughly as follows: firstly, stearic acid and caustic soda are reacted in a large...
