Abstract

The invention discloses a spraying quick-setting rubber asphalt waterproof coating and a preparation method thereof. The coating comprises a component A and a component B. The component A comprises unvulcanized rubber latex, anionic emulsified asphalt, stearate, colloidal sulfur, a first stabilizer and a pH regulator; and the component B comprises nano zinc oxide, dithiocarbamate, a second stabilizer, quaternary ammonium salt, calcium bromide and water. After the spraying quick-setting rubber asphalt waterproof coating is sprayed, vulcanization crosslinking among rubber particles can be realized, the acting force among the rubber particles in a coating is improved, and the problem of poor use performance caused by no crosslinking among the rubber particles after traditional rubber modified asphalt is sprayed is solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a spraying quick-setting rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Spraying quick-setting rubber asphalt waterproof coating is a two-component system, in which component A is a rubber-modified asphalt latex, and component B is a special curing agent solution. After the component reacts, it breaks the emulsion and adsorbs on the base layer, and solidifies to form a waterproof, anti-seepage, anti-corrosion and protective film. [0003] Generally, the rubber-modified asphalt latex of component A is compounded by anionic emulsified asphalt and rubber latex. Performance and bond strength have been effectively improved. For example, a rubber-modified asphalt waterproof coating disclosed in the prior art and its preparation method and use method, wherein the A component of the rubber-modified asphalt waterproof coatin...
