Problems solved by technology

[0003] Behenic acid amide is hardly soluble in most solvents at room temperature, is a waxy solid, insoluble in water, slightly soluble in organic solvents at room temperature, has good compatibility and adhesion with resins, and has good thermal stability. Stable in acid, alkali and water medium, behenic acid amide has poor compatibility with other components, easy to separate, low viscosity and poor fluidity

Abstract

The invention relates to a water-based behenamide emulsion and a preparation method thereof. The water-based behenamide emulsion comprises the following raw materials in parts by weight: 60-70 parts of purified water, 3-5 parts of a water-based efficient dispersant and 27-35 parts of solid behenamide. According to the water-based behenamide emulsion disclosed by the invention, through the combined action of the raw materials, the prepared water-based behenamide emulsion is uniform in dispersion, uniform and stable in emulsification system and not easy to layer, and has good properties of lubrication, demolding, isolation, smoothness and the like. According to the preparation method of the water-based behenamide emulsion, the purified water and the water-based efficient dispersing agent are firstly mixed to form the water-based behenamide emulsion, and the system can be more stable and not prone to layering; the particle size of the prepared water-based behenamide emulsion can reach 0.1-1 micron through high-speed shearing homogenization treatment, so that the lubricating performance of the system is better, and the system is more stable.
