Problems solved by technology

Due to the lack of special emulsifiers for erucamide, even if emulsifiers, dispersants and anti-sedimentation agents are added to the existing water-based erucamide emulsions, the dispersion effect is not good, and it is easy to precipitate, and flocculation will occur after long-term storage. layer phenomenon
In addition, the existing method requires high-speed stirring and grinding under heating conditions in the process of preparing water-based erucamide emulsion, the production process is complicated, and the production cost is high.

Abstract

The invention relates to the technical field of erucamide emulsion preparation, and specifically discloses a water-based erucamide emulsion and a preparation method thereof. The water-based erucamide emulsion comprises the following components in parts by weight: 35-45 parts of erucamide; 8-12 parts of new emulsifier; 1-2 parts of defoamer; 0.1-1 part of preservative; 50-80 parts of water. The water-based erucamide emulsion has a simple production process, good dispersion effect, and can be stored for a long time.

Description

technical field [0001] The invention relates to the technical field of erucamide emulsion preparation, in particular to a water-based erucamide emulsion and a preparation method thereof. Background technique [0002] Erucamide, also known as cis-13-docosenoic acid amide, is an excellent fine chemical product with a wide range of applications. Because of its high melting point and good thermal stability, it is often used as an anti-adhesive and slip agent for various plastics and resins, and an excellent lubricant and antistatic agent for extruded films. [0003] Since erucamide is insoluble in water, emulsifiers, dispersants, solubilizers and anti-sedimentation agents usually need to be added during the preparation of water-based erucamide emulsions to achieve dispersion and anti-sedimentation effects. Due to the lack of special emulsifiers for erucamide, even if emulsifiers, dispersants and anti-sedimentation agents are added to the existing water-based erucamide emulsions...
