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 stearic acid amide under stirring, and stir for 30 minutes until completely dispersed in In the system, add 0.1 kg of silane-based water-based defoamer, then perform ultrafine grinding and emulsification, so that the particle size of the stearic acid amide 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 stearic acid amide under stirring, and stir for 35 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 stearic acid amide 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 stearic acid amide under stirring, and stir for 40 minutes until completely dispersed in In the system, add 0.2kg of silane-based water-based defoamer, then perform ultrafine grinding and emulsification, so that the particle size of the stearic acid amide particles reaches the ultrafine size, stop grinding, and discharge.

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

Abstract

The invention provides a water emulsification dispersion liquor of ultramicro-hard fatty acid amide and manufacturing method. The liquor comprises by weight 1-4% of moistening dispersant agent, 4-40% of emulsifier, 15-35% of hard fatty acid amide, 0.1-0.2% of antifoam agent and 50.8-50.9% of de-ionized water. The production means is that installing de-ionized water into the pre-dispersion cooker, joining moistening dispersant agent, emulsifier, hard fatty acid amide orderly into the cooker under the mixing condition in 30-40 minutes so that they are dispersal in the system, joining antifoam agent, carrying out ultramicro grinding and emulsification so as to make granularity of hard fatty acid amide granulation less than 0.4 mum, stopping grinding and discharging. The water emulsification dispersion liquor of ultramicro-hard fatty acid amide, which is no bonding film, nonhazardous and can be used as sensililization agent for heat-sensitive paper or anti-friction material for coating paper, is widely applied in paper-making, plastic material and so on.

Description

technical field [0001] The invention relates to a stearic acid amide aqueous emulsified dispersion, in particular to an ultrafine stearic acid amide aqueous emulsified dispersion and a manufacturing method thereof, belonging to the technical field of sensitizers and lubricants. Background technique [0002] At present, stearic acid amide is widely used in papermaking, plastics and other industries as a lubricant, and there are many varieties of industrial lubricants and sensitizers sold on the market. Since stearic acid amide is insoluble in water, it is dispersed in the use system by particles and plays its role, so the particle size will directly affect the dispersion effect of 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 stearic acid amide, and stearic acid amide is also a highly emulsified substance that is difficul...
