[0003] Erucamide can be used to make erucamide emulsion as a slip agent for water-based inks, a lubricant for water-based paints, a release agent and release agent for rubber products, and leather coatings, etc., but because erucamide is insoluble in water , the usual erucamide has a large particle size, is not easy to disperse, and is easy to layer, and the ...

Abstract

The invention belongs to the technical field of lubricating agents, and particularly relates to a water-based erucyl amide emulsion, which is prepared from the following components in parts by weight:60 to 70 parts of deionized water, 30 to 40 parts of erucyl amide, 3 to 7 parts of dispersing agent, 1 to 3 parts of emulgator, 0.5 to 1.5 parts of solubilizer, 1 to 3 parts of water-based foam inhibitor, and 0.3 to 0.5 part of anti-settling agent. The particle size of the erucyl amide in the emulsion ranges from 0.1 to 1 mu m, and the emulsion is uniform in dispersion, even and stable, has excellent smoothness and lubrication performance when being used as a smooth agent for water-based ink and a lubrication agent for a water-based paint, and can be used for producing high-end leather. According to the preparation method of the water-based erucyl amide emulsion provided by the invention, a process is adjusted, the produced water-based erucyl amide emulsion is small in viscosity during aproduction process, and the water-based erucyl amide emulsion with the ground erucyl amide reaching a micrometer scale and even a nanoscale can be obtained favorably.
