What is Stearic Acid Amide

stearic acid amide is a white emulsion and is widely used as an important additive for synthetic materials such as plastics, rubber, chemical fibers, and coatings. Its unique chemical structure can not only significantly improve the processing performance of polymer resins, but to a certain extent can also endow products with good application performance.

Characteristics and Uses of Stearic Acid Amide


Stearic acid amide is non-toxic, non-polluting, harmless and environmentally friendly. It is easy to disperse in water and has the characteristics of ultra-fine, low viscosity and good dispersibility. Mainly used in inks, coatings, leather coatings, etc. to improve slip resistance, abrasion resistance and anti-blocking; it can also be used in textile post-processing additives, paper coatings, thermal paper sensitizers, etc.


Preparation of Stearic Acid Amide

Since stearic acid amide is insoluble in water, emulsifiers and dispersing agents need to be added in the process of preparing water-based stearic acid amide emulsion to achieve the dispersion effect. The existing water-based stearic acid amide emulsion still has poor dispersion effect even if emulsifier and dispersant are added, and it is easy to precipitate, and flocculation and stratification may occur after long-term storage. The preparation method of water-based stearic acid amide: first add stearic acid amide and emulsifiers A and B into water and stir for 60 min (stirring speed is 2500r/min), then add defoamer and preservative and stir for 40 min (stirring speed is 2500r /min) to obtain the aqueous stearic acid amide emulsion. The prepared water-based stearic acid amide emulsion has a solid content of 41.7% by weight and a viscosity of 146 mPa·S; the water-based stearic acid amide emulsion is centrifuged at 20000 r/min for 30 minutes, and no delamination is seen; Stearic acid amide emulsion was placed at 20~35℃ for 3 months without flocculation and stratification.
