Polyethylene wax (PEW) is a very efficient and valuable product that the production rate of this material is more than 10,000 tons per year in Iran petrochemical complexes, and modification it to oxidized wax for use in various industries such as paint, polymer, coating industry, and also one of the most widely used application of it is in production the emulsion of polyethylene waxes and, etc., which is economically very valuable. The aim of conducting this project is the production of water-based PEW emulsion, which requires the use of oxidized polyethylene wax (o-PEW). Produced polyethylene wax emulsion has wide and various applications in coating the different levels. Anionic, cationic and nonionic surfactants were used to prepare emulsion of polyethylene wax kind. In this project, the various percentages of surfactants and their effect were investigated on the made emulsion that the obtained results reflect this fact that the use of different percentages of surfactants does not cause change in the pH of the made emulsion. Nevertheless, stability, uniformity, and size of particles of obtained emulsion, are sustained non-negligible changes by changing the weight percentage of surfactants. In continue, using the potassium hydroxide (KOH) and its effect on the pH of the obtained emulsion were examined that obtained results showed an increase in the amount of pH of the emulsion with increasing the amount of used potassium hydroxide. In continue the effect of stirring speed and also conducting the tests of obtaining the acid number for synthetic waxes and also conducting the dynamic light scattering test (DLS) on the made emulsion were investigated to measure the size of synthesized particles.
