What is Water-based calcium stearate?
Calcium stearate lubricant is a water-insoluble metallic soap class surfactant. Generally, it is made as an aqueous liquid dispersion. Water-based calcium stearate refers to water-based calcium stearate, also known as calcium stearate emulsion and dispersion. Water-based calcium stearate is used as a white emulsion; it has an exceptionally slight smell and a slippery feel when it comes in contact with the skin. This product is mutually soluble in water, ethanol, or ether and is mainly used as a lubricant, anti-sticking agent, and glidant. It is especially suitable for producing oils and medicinal extracts with good fluidity and compressibility. They are used as a glidant in direct compression. It can also be used as a filter aid, clarifying agent, foam-dropping agent, suspending agent, and thickening agent for liquid preparations.
Application of water-based calcium stearate
Water-based calcium stearate is a stabilizer and lubricant of polychloroacetic acid, but it has poor stabilization and good long-term thermal stability. It can be used as non-toxic food packaging, medical equipment, and other soft film appliances. Used as a halogen absorbent for polyethylene and polypropylene, it can eliminate the adverse effect of a residual catalyst in the resin on the color and stability of the polish. It can also be used as a lubricant for polyolefin fibers and molded products. Water-based calcium stearate can also be used for phenolic, amino, and other thermosetting plastics. Moisturizing and releasing agents for polyester-reinforced plastics, thickening agents for grease, waterproofing agents for textiles, and flattening agents for paints.
Preparation of calcium stearate dispersion with low viscosity
Calcium stearate dispersion with low viscosity was prepared by an improved emulsifying process with stearic acid and calcium hydroxide as the primary raw materials. Single-factor tests studied the effects of dosage of the additive, variety, dosage, and composition of the emulsifier, the mass ratio of calcium hydroxide to stearic acid, and reaction time on dispersion properties, especially on the viscosity. Experimental results showed that the suitable mass ratio of the calcium hydroxide to stearic acid is 1.15∶1; using octyl phenol ethoxylate(OP-10) and oleoyl alcohol ethoxylate(O-20) at a mass ratio of 3∶1 as blend emulsifier with a dosage of 8%(mass of the blend emulsifier to the assembly of the total primary raw materials); dosage of the additive is 1.9%(w). At a reaction temperature of 90 ℃ for 1.5 h, a product dispersion with a solid content of 50%(w) at a dispersion level of 2 grade and viscosity of 59.7 mPa·s can be obtained.
