Embodiment 1

[0019] First add 79.9kg of deionized water into the pre-dispersion pot, then add 1kg of non-ionic dispersant and 4kg of modified PVA under stirring, then add 15kg of zinc stearate under stirring, and stir for 20 minutes until completely dispersed in In the system, add 0.1 kg of silane-based water-based defoamer, and then perform ultrafine grinding and emulsification, so that the particle size of the zinc stearate particles reaches the ultrafine size, stop grinding, and discharge.

Embodiment 2

[0021] First add 65.35kg of deionized water into the pre-dispersion pot, then add 2.5kg of non-ionic dispersant and 7kg of modified PVA under stirring, then add 25kg of zinc stearate under stirring, and stir for 30 minutes to completely disperse Add 0.15 kg of silane-based water-based defoamer to the system, then perform ultrafine grinding and emulsification, so that the particle size of the zinc stearate particles reaches the ultrafine size, stop grinding, and discharge.

Embodiment 3

[0023] First add 50.8kg of deionized water into the pre-dispersion pot, then add 4kg of non-ionic dispersant and 10kg of modified PVA under stirring, then add 35kg of zinc stearate under stirring, and stir for 50 minutes until completely dispersed in In the system, add 0.2kg of silane-based water-based defoamer, then carry out ultrafine grinding and emulsification, so that the particle size of the zinc stearate particles reaches the ultrafine size, stop grinding, and discharge.

[0024] After testing, the main physical performance indicators of various zinc stearate aqueous emulsified dispersions obtained by the technical solution of the present invention are shown in Table 1.

Abstract

The present invention provides a zinc stearate water emulsified dispersion liquor and its preparation method. Its composition includes the following components: (by wt%) 1-4% of wetting dispersing agent, 4-10% of emulsifying agent, 15-35% of zinc stearate, 0.1-0.2% of defoaming agent and 50.8-79.9% deionized water. 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 [0001] The invention relates to an aqueous zinc stearate emulsified dispersion, in particular to an ultrafine zinc stearate aqueous emulsified dispersion and a manufacturing method thereof, belonging to the technical fields of sensitizers and lubricants. Background technique [0002] At present, zinc stearate is widely used in papermaking, plastics and other industries as a lubricant, and there are many varieties of industrial lubricants and sensitizers on the market. Since zinc stearate is insoluble in water, it is dispersed in the use system by particles and plays its role, so the size of the particles will directly affect the dispersion effect of the active ingredients. Usually, the particle size is large, not easy to disperse, and easy to precipitate, so the use effect is not satisfactory. It is difficult for ordinary production tools to micronize zinc stearate, and zinc stearate is also a highly emulsified substance that is difficult to emulsify. There...
