Zinic stearas production technique is the earliest double decomposition.Its technological process is roughly, and first the reaction in a large amount of water mediums of stearic acid and caustic soda is obtained to sodium stearate, then adds zinc salt to carry out metathesis to obtain Zinic stearas and corresponding water-soluble sodium salt.Being filtered dry a large amount of clear water of rear use carries out the clean post-drying of rinsing, pulverizes and obtain Zinic stearas.The whole technological process production cycle is long, complicated operation, and labour intensity is large, and production cost is high, and wastewater flow rate is large.So, for adapting to the needs of high-end field of plastics processing, further widen Zinic stearas market, be necessary the production technique of Zinic stearas to improve.
Summary of the invention
For the deficiencies in the prior art; technical problem to be solved by this invention is; provide a kind of preparation technology simple; easily implement; good product quality, has reduced workman's labour intensity, has improved productivity and economic benefit; reduce the impact on environment, protected the preparation method of the modified form Zinic stearas of surrounding enviroment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of preparation method of modified form Zinic stearas, comprises the following steps:
(1) it is 80: 10 by the mass ratio of the compound of stearic acid, zinc, catalyzer, deionized water: 6:4 gets raw material;
(2) be heated to after 70-95 ℃ in stearic acid, deionized water being put into reactor under normal pressure, add the compound reaction 0.5 hour of zinc, temperature of reaction is 75-105 ℃;
(3) in reactor, add the raw material in catalyzer high-speed stirring reactor, whole process maintains the temperature at 95-155 ℃, churning time 0.8-1.5 hour, and cooling rear discharging, obtains Zinic stearas.
The preparation method of above-mentioned modified form Zinic stearas, the compound of described zinc is zinc oxide.
The preparation method of above-mentioned modified form Zinic stearas, described zinc oxide purity >99.6%.
Preparation method's advantage of modified form Zinic stearas of the present invention is:
1, the preparation method of modified form Zinic stearas of the present invention, preparation technology is simple, easily implements, and has reduced workman's labour intensity, has improved productivity and economic benefit, has reduced the impact on environment, has protected the environment of periphery.
2, see by batch production situation, this process costs is lower, and product detects through higher level's quality department, all reaches the Ministry of Chemical Industry's industry standard first grade specification of quality.This technique can improve company technique level, quality product, reduces production costs, and improves the competitive power of company's product in market, reaches the object of energy-saving and emission-reduction.
