Abstract

An SBS modified asphalt heat insulation and waterproofing coil belongs to the technical field of waterproof materials. The SBS modified asphalt heat insulation and waterproofing coil comprises a waterproof layer and a heat insulation layer, an SBS modified asphalt layer is arranged on the waterproof layer, the upper surface of the heat insulation layer is provided with a polyester film isolation layer, a braided cloth layer is arranged between the heat insulation layer and the SBS modified asphalt layer, and all above layers are respectively thermocompression-bonded to form one body. The SBS modified asphalt heat insulation and waterproofing coil has the advantages of good waterproof effect, simple structure, energy saving, environmental protection, low cost, high strength, convenience in construction, no harmful substances in the production process, no adhesion, high softness, high strength and high toughness, and is especially suitable for constructing the top surfaces of subways, tunnels and dam water gates.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to an SBS modified asphalt thermal insulation and waterproof coiled material, which belongs to the technical field of waterproof materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building, which is the first barrier for waterproofing of the whole project and plays a vital role in the whole project. The main products are asphalt waterproofing membrane and polymer waterproofing membrane. However, the existing waterproof membrane has the problems of poor low-temperature flexibility, easy aging, poor anti-degeneration performance and short service life. Contents of the invention [0003] The object of the present invent...
