Problems solved by technology

Due to the lack of special emulsifiers for oleic acid amide, even if the existing water-based oleic acid amide emulsions are added with emulsifiers, dispersants and anti-sedimentation agents, the dispersion effect is not good, 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 oleic acid amide emulsion, the production process is complicated, and the production cost is high

Abstract

The invention relates to the technical field of oleic acid amide preparation, and specifically discloses a water-based oleic acid amide emulsion and a preparation method thereof. The water-based oleic acid amide emulsion comprises the following components in parts by weight: 30-40 parts of oleic acid amide; 3-6 parts of new emulsifier; 1-2 parts of defoamer; 0.1-1 part of preservative; 50-70 parts of water. The production process of the water-based oleic acid amide emulsion is simple, and the dispersion effect is good, and it can be stored for a long time.

Description

technical field [0001] The invention relates to the technical field of oleic acid amide preparation, in particular to a water-based oleic acid amide emulsion and a preparation method thereof. Background technique [0002] Oleic acid amide, also known as cis-9-octadecenoamide, belongs to unsaturated fatty acid amide, which is a white crystalline or granular solid with polymorphic structure. Insoluble in water, soluble in ethanol, ether, acetone and other organic solvents. It is often used as a lubricant, antistatic agent, and anti-caking additive for polyolefin, polyvinyl chloride, polystyrene, phenolic resin, amino resin, polyester, acetate fiber, nitrocellulose, etc. [0003] Since oleic acid amide is insoluble in water, it is usually necessary to add emulsifiers, dispersants, solubilizers and anti-sedimentation agents in the process of preparing water-based oleic acid amide emulsions to achieve dispersion and anti-settling effects. Due to the lack of special emulsifiers ...
