Abstract

The present invention relates to a high-extension copper tire based root puncture-resistant waterproofing coiled material. The waterproofing coiled material has a multilayer composite structure comprising an intermediate layer and a modified asphalt coating. The middle layer is a composite copper tire based non-woven fabric, and the upper and lower surfaces of the composite copper tire based non-woven fabric are coated with the modified asphalt coatings. The components of the modified asphalt coating comprise, by weight, 100 parts of matrix asphalt, 5-20 parts of a softener, 8-26 parts of a modifier, 5-15 parts of an extension accelerator, 0.1-0.5 part of an antioxidant and 0.1-1 part of a propionate derivative. The coiled material has excellent resistance to high and low temperature, high elongation percentage and root resistance performance.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a high-extensibility copper base base puncture-resistant waterproof coiled material and a preparation method thereof, belonging to the field of building waterproof materials. Background technique [0002] With the rapid development of urbanization and industrialization in our country, the building area has increased sharply and the green space has been continuously reduced. At the same time, the gas released by various energy consumption and automobile exhaust has continued to increase. The "urban heat island" effect is becoming more and more serious, and the ecological environment is deteriorating. One of the effective ways to solve the above problems is to develop planting roofs. [0003] Plant roots in planted roofing systems are known to be extremely penetrating and often penetrate waterproofing materials, causing building leakage. And when leakage occurs, it is difficult to...
