Abstract
The invention discloses an odorless water-based coating produced by using slag micro-powder, and a preparation method thereof. The preparation method comprises the following steps: adding water into areaction kettle, adjusting the rotating speed of the reaction kettle to 500 to 600 r/min, slowly adding hydroxyethyl cellulose in a stirring state, dispersing for 5 to 10 minutes to form a glue form,adding auxiliary agents such as a dispersing agent and a defoaming agent 5 to 10 minutes later, stirring for 5-10 minutes, then adding slag micro-powder, titanium dioxide, talcum powder, ground calcium carbonate powder and the like into a solution, stirring for 20 to 40 minutes to reduce the fineness of the coating to 50 [mu]m or less, grinding to below 50 [mu]m or less for the next step of operation if the fineness is too high , reducing the rotating speed to 500 r/min, adding an emulsion, a defoaming agent and the like, adding auxiliary agents such as an odor-free emulsion, a coalescing agent and the like, adding a certain amount of pigment to adjust the system to the required color, and adjusting the viscosity of the system to 75-110 KU by using alkali swelling or a polyurethane thickener. No dust pollution or air pollution is ensured in the construction process, and the performance is excellent.
