Abstract

The invention relates to a novel water pipe joint nanometer waterproof film production process, which comprises: (1) preparing a base film: carrying out stirring mixing on nanometer silica, nanometer titanium dioxide and nanometer zinc oxide, adding to a bottom solvent formed by mixing a silicone acrylic emulsion and butyl acrylate, and carrying out mold pressing and sintering turning to obtain a base film; (2) preparing an antistatic coating material: carrying out stirring mixing on octadecyl amine and imidazolinium salt ethylacrylamide salt, and adding graphite to obtain an antistatic coating material; and (3) preparing a nanometer waterproof film: spraying the antistatic coating material onto both surfaces of the base film to obtain the nanometer waterproof film. According to the present invention, the process is simple, the novel formula and the novel dosage form are used, the long-term use of the water pipe joint is effectively ensured, effects of water resistance and seepage resistance are provided, and the cost is reduced.

Description

Technical field [0001] The invention relates to a nano waterproof technology, in particular to a production process of a novel nano waterproof film for a water pipe joint. Background technique [0002] Drainage pipes are mainly responsible for drainage of rainwater, sewage, irrigation and drainage of farmland, and can be divided into concrete pipes and reinforced concrete pipes according to their materials. Due to the long water delivery distance, it is usually necessary to connect multiple drain pipes or elbows to complete the water flow to the designated location. The drain pipe and the drain pipe, or the drain pipe and the drain elbow, are usually mechanically matched. Then use waterproof tape to complete the connection of the drainage pipes. However, due to the limitation of the working environment of the drainage pipes, this type of waterproof leakage method is prone to corrosion and seepage under the condition of long-term infiltration of sewage and high soil cover humidity...
