Description
Technical Field
The invention relates to an asphalt waterproof coating, in particular to a heat-reflection type color spraying quick-setting rubber asphalt waterproof coating and a preparation method thereof, belonging to the field of waterproof coatings.
Background
In recent years, the spraying quick-setting rubber asphalt waterproof coating is rapidly developed due to quick construction and excellent performance. The rubber asphalt emulsion is composed of a component A of rubber asphalt emulsion and a component B of a demulsifier, wherein the component A is composed of anionic high-solid-content emulsified asphalt, anionic neoprene latex, styrene-butadiene latex and other polymers, and is a water-based high polymer formed by blending and modifying. A, B components are mixed by special spraying equipment on site and then are demulsified and solidified quickly to form a waterproof coating. The multifunctional waterproof material integrates the functions of water resistance, corrosion resistance, seepage prevention and protection, and has wide application. However, asphalt is a material having a strong heat absorption property, and has a high heat radiation absorption rate to the sun, and asphalt can be converted from an elastomer to a plastomer at a high temperature, and its deformation resistance at a high temperature is rapidly reduced, and further, cracking, bubbling, sinking and the like occur.
And the traditional spraying quick-setting rubber asphalt waterproof paint is black in color, is very easy to absorb heat, and cannot meet the requirement of beautifying and decorating, so that the paint is inapplicable to exposed waterproof projects with higher visual effects and decoration requirements.

Although the above studies have provided some colored emulsified asphalts, the studies have not been yet matured, and improvements in the properties of the coatings are still needed. The important performance of the coating, such as water resistance, is not allowed in the actual production if the color is changed.
Therefore, the inventor group develops a heat-reflection type color spraying quick-setting rubber asphalt waterproof coating through years of research, and solves the problems that the color asphalt waterproof coating and the high aging resistance, self-healing performance and waterproof performance cannot be obtained simultaneously in the prior art.
