preparation example Construction

[0012] A preparation method of zinc stearate, said preparation method comprising:

[0013] Select a kneader that can be purchased from outside, and add all the above-mentioned components into the kneader at one time according to the proportion, control the temperature at 110-120°C, and knead the time at 1.6-2.4 hours.

[0014] A preferred embodiment of the present invention is: the preparation method includes: adding all the components into the kneader at one time according to the proportion, controlling the temperature at 115° C., and kneading for 2 hours.

Embodiment 1

[0015] Embodiment 1: a kind of zinc stearate, described zinc stearate is made up of following component and weight ratio: the stearic acid of 9.1 weight parts, the zinc oxide of 1.45 weight parts, the catalyst of 0.2 weight part; And Wherein the octadecane content in the stearic acid is more than 42%, the zinc content in the zinc oxide, that is, the zinc purity reaches more than 96%; the catalyst is hydrogen peroxide or ammonia.

[0016] A preparation method of zinc stearate, said preparation method comprising:

[0017] Select a kneader that can be purchased from outside, and add all the above-mentioned components into the kneader at one time according to the proportion, control the temperature at 115°C, and knead for 2 hours.

Embodiment 2

Abstract

The invention discloses a zinc stearate and a preparation method. The zinc stearate comprises, by weight, 8-10 parts of stearic acid, 1.2-2 parts of zinc oxide and 0.1-0.3 part of a catalyst, and is formed in a kneader by using a one-step method; the eighteen carbon content in the stearic acid is more than 42%, the zinc content, namely the degree of purity of zinc, of the calcium hydroxide is more than 96%, and hydrogen peroxide or ammonia water is selected to serve as the catalyst. The preparation method comprises the steps that a kneader which can be outsourced is selected and used, the components are added to the kneader according to proportion, temperature is controlled ranging from 110 DEG C to 120 DEG C, and the kneading time ranges from 1.6 h to 2.4 h. The calcium stearate and the preparation method have the advantages that the raw material sources are wide, the preparation process is simple, and the calcium stearate and the preparation method can be applied to the industries such as food, medicine and cosmetic conveniently and safely.

Description

technical field [0001] The invention relates to medicinal zinc stearate and a preparation method thereof, belonging to the technical field of auxiliary materials in industries such as pharmacy. Background technique [0002] Commonly used zinc stearate is a common industrial product, also known as zinc octadecanoate. Zinc stearate is mainly used as a lubricant and release agent for styrene resins, phenolic resins, and amino resins. At the same time, it also has the functions of vulcanization active agent and softener in rubber. Therefore, the above-mentioned zinc stearate is seldom used in products that directly contact the human body such as food, medicine, cosmetics, etc. at present, and its reason is the difference of material selection and preparation method. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a kind of zinc stearate and preparation method that a kind of raw material sour...
