<p>An exterior wall coating and preparation method therefor. The exterior wall coating comprises the following components: polyvinyl alcohol, light calcium carbonate, gentian violet, aluminum sulfate, sodium para-alkyl benzene sulfonate, and butanol. The weight ratios of components of polyvinyl alcohol:light calcium carbonate:gentian violet: aluminum sulfate:sodium para-alkyl benzene sulfonate:butanol are 1:12:6:1:0.6:0.1. The preparation method for the exterior wall coating comprises the following steps: using hot water to dissolve polyvinyl alcohol, sodium para-alkyl benzene sulfonate, and gentian violet; adding in aluminum sulfate and butanol; stirring to be uniform and then adding light calcium carbonate; stirring using a stirrer for 1.5 hours. The exterior wall coating has strong adhesiveness, is hard to peel, resistant to color change, and highly resistant to fog and mold.</p> |
