Its preparation method includes the following steps: firstly, adding the deionized water into a pre-dispersion kettle, then adding wetting dispersing agent emulsifying agent and stirring them, then adding zinc stearate and stirring them for 20-50 min, and adding defoaming agent, grinding and making emulsion so as to obtain the invented product.
Description
Technical field
The present invention relates to Zinc stearate water emulsified dispersed liquid, relate in particular to a kind of ultra micro Zinc stearate water emulsified dispersed liquid and manufacture method thereof, belong to sensitizer, lubricant technical field.
Background technology
At present, zinc stearate is widely used in industries such as papermaking, plastics as lubricant, and it is various in style for the industrial lubricants of being on sale throughout on the market, sensitizer.Because zinc stearate is water insoluble, be to be scattered in the use system and to bring into play it with particle to act on, so the big young pathbreaker of particle diameter directly influences the dispersion effect of active ingredient.Usually particle diameter is big, difficult disperses, and easy precipitation, and result of use is dissatisfied.The common tool of production is difficult to make zinc stearate to reach corpusculed, and zinc stearate also is the material of high emulsification difficulty simultaneously.So general zinc stearate is as lubricant, use is undesirable at its sensitizing of paper industry, lubricant effect, can not satisfy the production requirement of high-grade paper, special paper.
So, produce desirable Zinc stearate water emulsified dispersed liquid, on technology of preparing, must overcome technical barriers such as corpusculed, high emulsification treatment, need to adopt scientific formula and reasonable process conditions.
Summary of the invention
The purpose of this invention is to provide a kind of Zinc stearate water emulsified dispersed liquid and manufacture method thereof, adopt superfine grinding and special emulsification treatment technology and scientific formula, be intended to effectively solve problems such as zinc stearate content of effective, particle diameter, emulsification dispersion; Elimination is exposed to the conjunctiva phenomenon that occurs in the air, overcomes problems such as the crackle of paper coating when folding and decortication, and this product can be used as uses such as sensitizer, lubricant, is widely used in industries such as papermaking, plastics.
Purpose of the present invention is achieved through the following technical solutions:
Zinc stearate water emulsified dispersed liquid is characterized in that its component has following percentage by weight: wetting dispersing agent 1～4%, emulsifying agent 4～10%, zinc stearate 15～35%, defoamer 0.1～0.2%, deionized water 50.8～79.9%.
Further, above-mentioned Zinc stearate water emulsified dispersed liquid, described wetting dispersing agent are non-ionic dispersing agent, and described emulsifying agent is the modified polyvinylalcohol high polymer, and described defoamer is a silanes water-based defoamer.
Again further, the manufacture method of above-mentioned Zinc stearate water emulsified dispersed liquid is characterized in that: deionized water is added in the pre-dispersed pot earlier, under agitation add wetting dispersing agent and emulsifying agent then, under agitation add zinc stearate again, stirred 20～50 minutes, and made, add defoamer to being scattered in fully in the system, carry out superfine grinding and emulsification then, make the granularity of zinc stearate particle reach ultra micro level specification, stop to grind discharging.
Further, the manufacture method of above-mentioned Zinc stearate water emulsified dispersed liquid, the particle diameter after described zinc stearate particle grinds is less than 1 μ m.
The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in:
1. adopt the superfine grinding technology, realize pulverizing corpusculed, method is easy, and technology is reasonable;
2. use special emulsification treatment technology and scientific and reasonable compound method, the zinc stearate of the high emulsification difficulty of hydrophily is realized corpusculed through emulsification treatment, make its heat reactivity superior by corpusculed, use is an emulsifying agent to the little PVA of paper purposes influence, in the disperse water, form homogeneous latex emulsion rapidly;
3. atomic characteristic is given full play to its superior sensitizing effect;
4. the Zinc stearate water emulsified dispersed liquid that the present invention prepared is exposed in the air not conjunctiva, product is nontoxic, the feature of environmental protection good, sensitizing, lubricant effect are more satisfactory, can be used as the sensitizer of heat-sensitive paper, the uses such as lubricant of coated paper, are widely used in industries such as papermaking, plastics.
The specific embodiment:
The manufacturing prescription of Zinc stearate water emulsified dispersed liquid: wetting dispersing agent 1～4%, emulsifying agent 4～10%, zinc stearate 15～35%, defoamer 0.1～0.2%, deionized water 50.8～79.9%.Wherein: wetting dispersing agent is a non-ionic dispersing agent, active ingredient 100%; Emulsifying agent is modified polyvinylalcohol (PVA) high polymer; Defoamer is a silanes water-based defoamer.
The manufacturing technique of Zinc stearate water emulsified dispersed liquid: earlier deionized water is added in the pre-dispersed pot, under agitation add wetting dispersing agent and emulsifying agent then, under agitation add zinc stearate again, stirred 20～50 minutes, and made, add defoamer to being scattered in fully in the system, carry out superfine grinding and emulsification then, make the granularity of zinc stearate particle reach ultra micro level specification, stop to grind discharging; Below all add each material by the component requirement.
The present invention adopts the superfine grinding technology, and the zinc stearate particle is ground to below the 1 μ m by 75 original μ m through grinding, its particle diameter, realizes pulverizing corpusculed; Use special emulsification treatment technology and scientific and reasonable compound method, the zinc stearate of the high emulsification difficulty of hydrophily is realized corpusculed through emulsification treatment, superior by its heat reactivity of corpusculed, using the little PVA of paper purposes influence is emulsifying agent; In the disperse water, form homogeneous latex emulsion rapidly; Atomic characteristic is given full play to superior sensitizing effect.
