Abstract
The invention provides a preparation method of mixed wax capable of enhancing smoothness of a coating. The preparation method comprises the following steps: in a reaction kettle, adding a certain amount of dispersant, imitator, and polyethylene (PE) wax/hexafluoropropene trimer/silicyl vinyl unsaturated silane; heating to reaction temperature, thus obtaining surface-grafted PE wax powder after reaction; then, mixing the PE wax powder with polytetrafluoroethylene (PTFE) powder; and grinding and crushing the mixture in a flour mill to obtain the mixed wax provided by the invention. PE wax spheres are surface-modified through the hexafluoropropylene trimer and the hydrolytic silicyl vinyl unsaturated silane, so that the compatibility of the PE wax spheres with PTFE is improved. Meanwhile, the hexafluoropropene trimer and the hydrolytic silicyl vinyl unsaturated silane are polymerized to form a net structure with branch chains, thereby improving binding force of the PE wax powder with the PTFE micro powder in blending. The mixed wax can be widely applied to various water-based paints or alcohol soluble paints.
