Abstract

The invention belongs to the field of building materials, and particularly relates to a water-based asphalt coating and a preparation method thereof. The water-based asphalt coating is prepared from the following raw materials in percentage by weight: 40 to 80 percent of emulsified modified asphalt, 10 to 60 percent of polymer emulsion, 0.1 to 0.5 percent of amino silane solution and 0 to 30 percent of filler. The mechanical property of the prepared water-based asphalt coating is greatly improved compared with that of a common water-based asphalt coating, and the water-based asphalt coating can be compounded with a coiled material to be used for side wall waterproofing.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically relates to a water-based asphalt coating and a preparation method thereof. Background technique [0002] At present, the commonly used waterproof schemes in the field of side wall waterproofing include the composite system of coil and coil, and the composite system of coil and coating. However, in practical applications, the composite system of coil and coil is difficult to construct and the actual full viscosity is low. The composite system of coil material and coating has problems such as low peel strength and weak anti-slip ability, which eventually lead to poor application results. Compared with the composite system of coils and coils, the composite system of coatings and coils has wider applicability, especially the composite system of water-based asphalt coatings and coils. Water-based asphalt coatings have good adhesion to both dry and wet bases Good compatibility w...
