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 preparation of ethylene bis-stearic acid amide emulsion, and specifically discloses a water-based ethylene bis-stearic acid amide emulsion and a preparation method thereof. The water-based ethylene bis-stearic acid amide emulsion comprises the following components in parts by weight: 30-40 parts of ethylene bis-stearic acid amide; 5-10 parts of emulsifier A; 1-3 parts of emulsifier B; 1-2 parts of foaming agent; 0.1-1 part of preservative; 60-70 parts of deionized water. The water-based ethylene bis-stearic acid amide 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 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...
