Abstract
The invention discloses a tung oil modified paraffin emulsion and its preparation and application methods. The preparation method comprises the following steps: firstly mixing required paraffin and tung oil and an emulsifier, heating, stirring and fusing; then, adding water and stirring at high speed and simultaneously carrying out high-speed emulsification and shearing by the use of emulsification equipment; and finally naturally cooling. Solid concentration of the prepared tung oil modified paraffin emulsion is 30% and above, and its stability reaches 6 months and above. When the tung oil modified paraffin emulsion is used, a proper amount of a dry-promoter additive is doped in the tung oil modified paraffin emulsion so as to promote film-formation drying of the tung oil modified paraffin emulsion and simultaneously raise water resistance and adhesive force of a paraffine film. According to the invention, the problem that film-formation drying time of the paraffin emulsion is long during the concrete curing and using process, a formed paraffine film has poor adhesive force on the surface of concrete and poor water resistance and is easy to wash out by rain to lead to shedding and low water-retention rate of concrete is solved.
