Description

technical field [0001] The invention relates to a nanometer waterproof technology, in particular to a novel nanometer waterproof film for water pipe joints. Background technique [0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage, and can be divided into concrete pipes and reinforced concrete pipes according to their materials. Due to the generally long distance required for water delivery, it is usually necessary to connect multiple drain pipes or elbows to complete the flow of water to the designated location. Mechanical cooperation is usually used between the drain pipe and the drain pipe, or between the drain pipe and the drain elbow. Waterproof tape is then used to complete the interconnection of the drainage pipes. However, due to the limitation of the working environment of the drainage pipes, this waterproof leakage method is easy to corrode and seep water when the sewage is infiltrated for a long tim...
