Abstract
The invention provides a preparation method of bulk zinc stearate. The preparation method comprises the following steps: a. feeding stearic acid at normal pressure to a reaction kettle, heating up to 130-160 DEG C, then adding a catalyst and zinc oxide to the reaction kettle, and taking reaction for 80-120 minutes till reaching the molten state; b. adding an antioxidant, and stirring for 5-20 minutes; c. adding the molten zinc stearate prepared in the step b to a mold with a framework; d. cooling to obtain the required bulk zinc stearate with a certain shape. The preparation method disclosed by the invention is to add the molten zinc stearate prepared by the dry method to the framework to prepare the bulk zinc stearate, and cannot generate particles or microparticle dust in a processing workshop, so as to effectively improve the environment quality of the workshop, greatly reduce influence on health of workers in the workshop, and achieve a great promotional value and social significance.
Description
Technical field
The present invention relates to promoter material preparation field, be specifically related to a kind of preparation method of block Zinic stearas.
Background technology
Zinic stearas, Chinese another name: zinc octadecanate, stearic acid zinc salt, Zinic stearas (lightweight), stearic acid zinc salt, Stearic Acid zinc, Zinic stearas, white lightweight powdery, proportion 1.095, there is soapy feeling, be not soluted in water, be dissolved in the ethanol of heat, benzene and turpentine wet goods organic solvent, meet strong acid and be then decomposed into stearic acid and corresponding zinc salt, this product has water absorbability.
The purposes of Zinic stearas widely, most common use: make thermo-stabilizer, lubricant, polishing agent, promotor, thickening material, sour trapping agent etc.
Current shape of product is on the market common is powdery, pearl, sheet.Powder-like product is generally used for the polishing agent of coating, and pearl and sheet are usually used in lubricant and the dispersion agent of modified plastics, filling master batch, colour batch etc.Although pearl and sheet can meet the processing request of most of modified plastics and filling master batch, colour batch at present, but to petrochemical industry polyolefine industry, use Banbury mixer to do look mother, filling master batch etc. to environment and the very high industry of craft precision requirement, can't meet the demands completely.
For the manufacturing enterprise of Zinic stearas, also there is certain dust production safety hidden danger in powder-like product and beaded product, and in transportation, easily the group of connecing, sheet such as to be squeezed at the situation such as sheet and part micro mist that diminishes flaked product.
How developing a kind of Zinic stearas working method being convenient to pack, transport and meet special industry requirement, is the difficult problem needing at present to capture.
Summary of the invention
Object of the present invention provides a kind of preparation method of block Zinic stearas, can make to reduce in Zinic stearas wrapping process after processing to the pollution of environment and the healthy effect being reduced to workshop packaging personnel.
For realizing object of the present invention, the invention provides following technical scheme:
A preparation method for block Zinic stearas, a, at ambient pressure stearic acid is put in reactor be heated to 130-160 DEG C after add catalyzer and zinc oxide reaction 80-120 minute for molten state; B, add oxidation inhibitor stir 5-20 minute; Adding in c, the Zinic stearas of melting that obtained by step b is placed with in the mould of skeleton; The block Zinic stearas of obtained required definite shape after d, cooling.
Described skeleton is polyethylene silk screen.
The weight ratio of described stearic acid, zinc oxide and oxidation inhibitor is: 1400:210-220:3-7.
Described catalyzer and stearic weight ratio are 50-85:1400.
Described catalyzer is one or more in water, ethanol, citric acid, hydrogen peroxide, acetic acid, sodium bisulfite, SODIUM PHOSPHATE, MONOBASIC and sodium pyrosulfate; Described oxidation inhibitor is epoxy compounds.
The preparation method of block Zinic stearas of the present invention, is equally applicable to the processing of calcium stearate, Magnesium Stearate, lithium stearate.
A purposes for block Zinic stearas, for banburying mach look mother, high-grade stopping composition and the polymerization of polyolefine petrochemical industry.
The invention has the advantages that:
1, the Zinic stearas of melting obtained online is directly added obtained block Zinic stearas in skeleton by the present invention, in job shop without particle or microparticle dust, effectively improves the environmental quality in workshop, greatly reduces the healthy effect to shop worker.
2, conveniently, reduce the requirement of meeting storage condition, spontaneous combustion or explosion index reduce for obtained block Zinic stearas transport and storage.
3, adding polythene net net in the present invention is skeleton, can block Zinic stearas crushing be cut off by nylon wire when needed or pull.
4, advantage of the present invention is: not airborne dust, and convenient transportation is non-friable, and damaged.
