Pavement coating material and preparation method thereof

Abstract

Provided are a pavement coating material and a preparation method thereof. The method for preparing a pavement coating material, includes: S1, adding a film-forming aid to a pure acrylic emulsion and mixing, to obtain an organic material; S2, adding a silane coupling agent to a silica sol and mixing, to obtain an inorganic material; S3, adding a part of a dispersant and a nano-catalyst to deionized water and mixing, to obtain a catalyst aqueous solution; and S4, mixing the organic material and the inorganic material by stirring to obtain a mixed base material, adding the catalyst aqueous solution, a hollow microbead, titanium dioxide, and carbon black sequentially to the mixed base material and mixing, to obtain a mixture, and adding a remaining part of the dispersant and a defoamer to the mixture and mixing, to obtain the pavement coating material.
