About Stearic Acid Amide Emulsion:
Stearic acid amide is a white emulsion, the product is non-toxic, non-polluting, non-hazardous, and environmentally friendly. It is easy to disperse in water and has the characteristics of ultra-fineness, low viscosity, and good dispersibility.
Stearamide is also called stearamide. Its chemical formula is C17H35CONH2. The stearic acid amide insoluble in water, slightly soluble in organic solvents at room temperature. It can improve the dispersion effect and affinity of dyes and pigments.
Good adhesion, lubricity and mold release, no moisture absorption and other advantages. It is miscible with paraffin wax. The ammonium salt is formed by the reaction of stearic acid and ammonia and then dehydrated to obtain the final product. It has no hygroscopicity, good smoothness, can improve the dispersion effect of pigments and dyes, and has lubricity and mold release properties. Used as a surface-active agent, fiber oil agent, release agent, polyvinyl chloride and urea resin lubricant, pigment ink and color crayons mixed agent.
Stearamide can be used as a sensitizer and slip agent in thermal paper coatings, as well as a slip agent and anti-blocking agent in polyolefin films. Stearates are based on fatty saturated linear monocarboxylic acids derived from natural vegetable oils.

How is Stearic Acid Amide Emulsion produced?
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 a poor dispersion effect even with the addition of emulsifier and dispersant and is easy to precipitate, and flocculation and stratification may occur after long-term storage. In addition, the existing method requires high-speed stirring and grinding under heating conditions in the process of preparing the aqueous stearic acid amide emulsion, the production process is complicated, and the production cost is high.
The preparation method of water-based stearic acid amide: first add stearic acid amide and emulsifiers A and B to 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 solids content of 41.7% by weight and a viscosity of 146 mPa·S; the water-based stearic acid amide emulsion is centrifuged at 20000r/min for 30 minutes, and no delamination is seen; Stearic acid amide emulsion was placed at 20-35°C for 3 months without flocculation and delamination.
Applications of Stearic Acid Amide Emulsion:
Plastics and rubber processing: stearic acid amide emulsions are mainly used as lubricants and dispersants in plastics and rubber processing. It can reduce the friction coefficient of materials, reduce wear, improve production efficiency and product quality. In addition, stearic acid amide emulsion can also improve the processing properties of plastics and rubber, reduce energy consumption and reduce production costs.
Coatings and paints: Stearic acid amide emulsions are used primarily as thickeners and stabilizers in coatings and paints. It can improve the viscosity and stability of the coating and prevent the coating from settling and delamination. At the same time, stearic acid amide emulsion can also improve the leveling and gloss of the coating, making the coating more smooth and beautiful.
Adhesives and sealants: stearic acid amide emulsions are mainly used in adhesives and sealants as viscosifiers and leveling agents. It can improve the initial viscosity and retention of the adhesive, so that the adhesive can better adhere to the surface of the adhesive. At the same time, the stearic acid amide emulsion can also improve the constructability and sealing performance of the sealant, making the sealant more uniform and dense.
Personal care products: Stearic acid amide emulsions are used primarily as emulsifiers and stabilizers in personal care products. It can improve the stability and moisture of the product, making the product more delicate and easy to apply. For example, adding stearic acid amide emulsion to lip balm can increase the flexibility and moisturization of lip balm, and improve the use experience of lip balm.
Pharmaceutical and medical: stearic acid amide emulsion is mainly used as a drug carrier and drug additive in pharmaceutical and medical treatment. It can improve the stability and solubility of the drug, making the drug easier to absorb and use. In addition, stearic acid amide emulsion can also be used to make drug microspheres and drug patches to improve the efficacy and targeting of drugs.
Agriculture and plant growth: Stearate amide emulsions are used primarily as plant growth regulators in agriculture and plant growth. It can improve the stress resistance and disease resistance of plants, and enhance the adaptability and tolerance of plants. At the same time, stearic acid amide emulsion can also promote plant root growth and chlorophyll synthesis, improve plant growth rate and yield.
Metal processing: stearic acid amide emulsion is mainly used as a lubricant and protective agent in metal processing. It can reduce the friction and wear of the metal surface and improve the processing accuracy and surface quality of the metal. In addition, stearic acid amide emulsion can also prevent metal oxidation and corrosion, extending the service life of the metal.
Textile processing: stearic acid amide emulsion is mainly used as softening agent and antistatic agent in textile processing. It can improve the softness and comfort of textiles, making textiles more suitable for wearing and use. At the same time, stearic acid amide emulsion can also reduce the surface resistance of textiles and improve the antistatic properties of textiles.
Water treatment and environmental protection: stearic acid amide emulsion is mainly used as flocculant and precipitator in water treatment and environmental protection. It can improve the efficiency and quality of water treatment, making the water more pure and clear. At the same time, stearic acid amide emulsion can also be used for waste oil and wastewater treatment to reduce environmental pollution.
Electronics and appliances: Stearic acid amide emulsion is mainly used as insulation material and cable material in electronics and appliances. It can improve the insulation performance and weather resistance of electronic products to ensure the safety and service life of electronic products. At the same time, stearic acid amide emulsion can also be used to make cable insulation layer and cable joint protective agent.
