Abstract

The invention discloses a composite waterproof structure and a preparation method thereof, and belongs to the field of building waterproof materials. The composite waterproof structure is prepared from a waterproof coil layer, a reaction type macromolecular elastic coating layer and a waterproof base layer in turn from top to bottom, wherein the waterproof coil layer is prepared from an upper surface layer and a self-sticking material layer in turn from top to bottom; the self-sticking layer is self-sticking polymer modified asphalt. According to the composite waterproof structure and the preparation method thereof disclosed by the invention, separation between the coating and the coil is avoided, and the waterproof effect is perfect.

Description

technical field [0001] The invention belongs to the field of building waterproof materials, and in particular relates to a composite waterproof structure and a preparation method. Background technique [0002] With the development and progress of modern society, waterproofing occupies an increasingly important position in the modern construction industry and has become an important factor affecting people's work and life. In order to solve the problems and defects caused by using waterproof coatings or coils alone, people began to combine coatings and coils to form a composite waterproof system. Nowadays, the more popular non-curing composite waterproof system will delaminate from the coating and the membrane as time goes by, making it difficult to guarantee the waterproof quality. Contents of the invention [0003] In order to solve the above-mentioned problems of delamination of the paint and the coiled material and difficulty in ensuring waterproof quality, the present...
