Problems solved by technology

Due to the lack of special emulsifiers for ethylene bis stearic acid amide, even if the existing water-based ethylene bis stearic acid amide emulsions are added with emulsifiers, dispersants and anti-sedimentation agents, the dispersion effect is still poor, easy to precipitate, and long-term Flocculation and stratification will occur after time is left
In addition, the existing method requires high-speed stirring and grinding under heating conditions in the process of preparing water-based ethylene bis-stearic acid amide emulsion, the production process is complicated, and the production cost is high.

Abstract

The invention relates to the technical field of ethylene bisstearamide emulsion preparation and specifically discloses a waterborne ethylene bisstearamide emulsion and a preparation method thereof. The waterborne ethylene bisstearamide emulsion comprises the following components in parts by weight: 30-40 parts of ethylene bisstearamide, 5-10 parts of emulsifying agent A, 1-3 parts of emulsifying agent B, 1-2 parts of defoaming agent, 0.1-1 part of preservative and 60-70 parts of deionized water. The waterborne ethylene bisstearamide emulsion is simple in production process and good in dispersion effect and can be stored and placed for a long term.

Description

technical field [0001] The invention relates to the technical field of preparation of ethylene bis-stearic acid amide emulsion, in particular to a water-based ethylene bis-stearic acid amide emulsion and a preparation method thereof. Background technique [0002] Ethylene bis-stearamide, also known as vinyl bis-stearamide, is a hard and brittle white high-melting point wax. Its industrial products are small yellowish particles. It is non-toxic, has no side effects on the human body, and is insoluble at room temperature. For most solvents, it is often used as plastic lubricants and additives for paints and inks. [0003] Since ethylene bis stearic acid amide is insoluble in water, it is usually necessary to add emulsifiers, dispersants, solubilizers and anti-settling agents in the process of preparing water-based ethylene bis stearic acid amide emulsions to achieve dispersion and anti-settling effects. Due to the lack of special emulsifiers for ethylene bis stearic acid amid...
