Abstract

A process for preparing high-stability emulsified paraffin wax is characterized by that the paraffin wax is emulsified by cationic surfactant as emulsifier in weakly acidic condition. The resultant paraffin wax emulsion has features of high stability, flowability and content of paraffin wax, and fine granularity.

Description

(1) Technical field: [0001] The invention belongs to the invention of chemical product manufacturing method (two) background technology: [0002] Emulsified paraffin is an emulsion in which paraffin is stably dispersed in water by emulsifiers and other additives. To prepare a kind of emulsified paraffin wax with good stability, its preparation technology is very difficult. Most of the currently produced emulsified paraffins use anionic surfactants, nonionic surfactants or fatty acid soaps as emulsifiers under alkaline conditions. The disadvantage of this method is that the amount of emulsifier is large and the stability of the emulsion is poor. The prepared emulsified paraffin is generally treated with a homogenizer or a colloid mill to improve its stability, and the production process is complicated, the technology is difficult to master, and the production cost is high. [0003] The purpose of the present invention is: under the premise of improving the stability of emu...
