Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building materials, and more particularly relates to a non-asphalt-based non-cured waterproof coating, a preparation method and application thereof. BACKGROUND

[0002] The root penetration resistant waterproof layer is one of the basic structure layers of the roof and garage greening of a building, and is usually composed of a common waterproof layer and a root penetration resistant layer. The root penetration resistant waterproof layer is mainly composed of a root penetration resistant waterproof roll material. Although the waterproof roll material is uniform in thickness and stable in root penetration resistance, a large number of joints make water have the possibility of penetration, and the human factors during construction cause the root penetration resistance to fail due to the failure of adhesion to the base layer. The combination of the waterproof coating and the waterproof roll material can be applied to any complex-shaped base surface and form a dense and seamless root resistant system. Therefore, the construction of the new root penetration resistant waterproof layer by the coating-roll combination is the key process for the success of the roof and garage greening.

[0003] The non-asphalt-based non-cured waterproof coating is mainly composed of softening oil, petroleum resin, rubber and other materials. The waterproof product has good high-temperature and low-temperature performance. However, due to the compatibility problem of the chemical root inhibitor in the coating, the elongation performance, heat aging performance and thermal stability of the non-asphalt-based non-cured waterproof coating are reduced. At the same time, the adhesion of the coating in the prior art is poor, and the connection with the waterproof roll material is unstable, which easily causes waterproof failure.

[0004] Therefore, it is of great significance to develop a non-asphalt-based non-cured waterproof coating with high elongation performance and high stability (heat aging resistance) for constructing a new coating-roll combined root penetration resistant waterproof system and realizing the waterproof requirement with the same service life as the planted roof building.
