Abstract

The invention provides a macromolecular composite membrane modified bituminous waterproof roll. The roll comprises at least one macromolecular composite membrane and at least one modified bituminous size layer bonded to the at least one macromolecular composite membrane, wherein the macromolecular composite membrane adopts a multilayer structure and can prevent layer separation, resist high temperatures and resist ultraviolet rays. Through optimization design of different membrane layer structures and materials of the multilayer macromolecular composite membranes in the macromolecular composite membrane modified bituminous waterproof roll, the waterproof roll has good bituminous swelling resistance and permeability, has good ultraviolet resistance at the high temperature and under ultraviolet irradiation and has the significant waterproof effect, and separation of composite membrane layers cannot occur easily.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a polymer composite membrane modified asphalt waterproof coiled material. Background technique [0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and prevent groundwater leakage. As the non-leakage connection between the engineering foundation and the building, the waterproof membrane is the first barrier for the waterproofing of the entire project and plays a vital role in the waterproof quality of the entire project. Waterproof membrane is a flexible building material product that can be rolled into a roll, and is made of asphalt or polymer waterproof material impregnated on the carcass. According to the different main components, it can be divided into asphalt waterproof membrane, polymer modified asphalt waterproof membrane and synthetic polymer waterproof membrane. According to the...
