Problems solved by technology

[0005] (3) Once the two components of the epoxy resin potting material are mixed, the crosslinking reaction starts and the viscosity increases. When the viscosity is high enough, the perfusion pipe will be blocked. Due to the need to balance the curing speed and operating time, the operating time is generally less than 40 Minutes, the risk of pipe blockage is high if the depth of perfusion is below 100 meters

Description

Technical field: [0001] The invention relates to a polymer perfusion material for deep-sea repair equipment and a preparation method thereof. technical background: [0002] In marine engineering, when underwater pipelines, structures and other equipment are corroded by the marine environment for a long time and fail to meet the original design requirements, they need to be repaired. Infusion repair is widely used as an important repair process. This method can restore the original size of the equipment without leaving a gap. Cement or underwater epoxy resin is usually used for on-site construction, because the cost of dismantling or replacing equipment is huge. The performance of specially designed underwater epoxy resin infusion is usually better than that of cement, but it also has the following defects: [0003] (1) Ordinary underwater epoxy resin potting material obtains adhesion by absorbing or emulsifying the moisture on the surface of the metal substrate, but cannot absorb...
