[0002] As an indispensable key material in the construction industry, waterproof membrane refers to a rollable block-shaped waterproof material made through a specific production process. These materials usually use specially made paper, chemical fiber paper or cotton fabric as the base material, and are impregnated with modified asphalt, asphalt mastic or polymer asphalt concrete to provide waterproof protection. Waterproof membrane is widely used in engineering fields such as building walls, roofs, tunnels, roads and landfills. As the first line of defense against external rainwater and groundwater leakage, its importance is self-evident.

They lack sufficient weather resistance and are prone to aging and cracking under extreme climatic conditions, thus affecting their waterproof performance. The membrane lacks a self-adhesive layer design, which complicates the construction process and reduces construction efficiency. Therefore, a modified asphalt waterproof membrane is proposed.

SBS polymer asphalt is the core material of the waterproof layer, which has excellent waterproof performance and good adhesion, and can ensure that the coiled material forms a continuous waterproof barrier during use.
