Abstract

The invention discloses a composite spraying quick-setting emulsifier and a preparation method, a preparation method of an anionic emulsified asphalt based on the composite spraying quick-setting emulsifier, and a waterproof coating using the anionic emulsified asphalt. The composite spraying quick-setting emulsifier includes 50%-90% of anionic surfactant, 5%-20% of polyamine, and 5%-40% of betaine. The preparation method is as follows: adding polyamine to the anionic surfactant, stirring at 40°C for 2-4h, and mixing uniformly to obtain product A, adding betaine to product A, stirring at 40°C for 2-4h, and mixing uniformly. The emulsifier of the invention has better cohesive force with the base surface, can emulsify the SBS modified asphalt, and the prepared emulsified asphalt has good stability.
