Abstract
This invention provides a producing method of high lever fatty acid lubricant, which consists of unfreezing the high lever fatty acid, adding the emulsifying agent, then the talked high lever fatty acid can be emulsified to translucence latex, next the dispersant is added into the solution to stable, and the alkali compound is added and mixed to react for 4-8 hours at 50-95deg.C, at last the producer is dispersed, homogenized to get the high lever fatty acid lubricant. The advantage of this invention not only has small particle radium and low viscidity, but also the stability is good and the usage volume is low. Because the particle radium of this invention is small, the contrast surface area is large, so during the high speed coating, the dope can disperse homely, the fluidity and even is good. It can effectively solve the draw of current stearic acid calcium lubricant.
Description
Technical field
The present invention relates to a kind of is the preparation method of the ultra-fine lubricant of raw material with the higher fatty acid salt, mainly as paper making and cloth coating process auxiliary agent and functional aid.
Technical background
Higher fatty acid salt lubricant is a water-insoluble metallic soap class surfactant, and the domestic SCD dispersion liquid that is commonly called as claims NOPCOTE C-104 abroad.Generally be made into the aqueous suspension dispersion liquid about 50%, be added in the coating with 0.5～5% of pigment oven-dry weight, its lubrication is very obvious.
The higher fatty acid salt dispersion liquid is just used in the paper industry in China as far back as the beginning of the eighties in last century as the coating lubricant of coated paper, and calcium stearate lubricant production at present spreads all over the country, but solid content basically all between 40～45%, solid content is on the low side.Storage time is long slightly, and the easy brightness reversion of product has peculiar smell, phenomenons such as easy layering.A small amount of in addition high product of solid content, the viscosity height, the particle of dispersate is thick.
Summary of the invention
The objective of the invention is to disclose a kind of preparation method of higher fatty acid salt lubricant, to overcome the above-mentioned defective that prior art exists.
Method of the present invention comprises the steps:
With the higher fatty acids heat temperature raising to dissolving, add emulsifying agent then, said higher fatty acids emulsification is become translucent emulsion, add dispersant then and stablize, stir, add alkali compounds, 50～95 ℃ ℃ were reacted 4～8 hours, with the product that obtains, adopt mechanical means, disperse, homogeneous promptly obtains higher fatty acid salt lubricant;
The emulsifying agent addition is 0.5～5% of an alkali compounds quality;
The addition of dispersant is 0.2～3% of an alkali compounds quality;
The mol ratio of higher fatty acids and alkali compounds is: 1: 2～3;
It is 12～30 aliphatic acid that said higher fatty acids is selected from carbon number, preferred laurate, stearic acid, palmitic acid or triacontanoic acid;
Alkali compounds is selected from calcium hydroxide, magnesium hydroxide, calcium oxide or zinc oxide.
Said dispersant is selected from one or more mixtures in polycarboxylate, polyacrylate or the fatty alcohol-polyoxyethylene ether silane, optimization polypropylene acid sodium, enuatrol, methyl trichlorosilane or polyacrylic acid potassium;
Said emulsifying agent is selected from aliphatic acid polyethenoxy ether, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene or its mixture,, preferred sorbitan monooleate, polyoxyethylene nonylphenol, polyoxyethylene fatty acid ester or its mixture.
Prepared lubricant viscosity scope 250～500cps, particle size range 20～80nm, weight solid content are 10～55%.
The higher fatty acid salt lubricant that the present invention synthesizes, at first higher fatty acids is emulsified into translucent microemulsion with emulsifying agent, it is stable to add dispersant then, and then slowly add alkali compounds and generate higher fatty acid salt, in this course of reaction, keep the excessive sufficient reacting that could make of alkali compounds, otherwise can directly influence the stability of product.
Higher fatty acid salt lubricant particle size range 20～80nm that the present invention synthesizes, viscosity 250～500cps, solid content 10～55% has good flowability simultaneously.
Compare with existing home products, it is little that the present invention not only has a particle diameter, the advantage that viscosity is low, and have good stability, the advantage that consumption is few.Because this product cut size is little, specific area is big, and dispersion is even and mobile in the high-speed coating process of coating, levelability is all better.Solved the technological deficiency that present calcium stearate lubricant is produced effectively.
