Abstract
Description
technical field
[0001] The invention relates to an underwater repair material, more specifically an epoxy / polyurethane interpenetrating polymer network underwater repair material; the invention also relates to the preparation method and application of the underwater repair material. Background technique
[0002] Concrete defects are one of the most common and common diseases of hydraulic concrete buildings, especially the underwater part of concrete. Due to the long-term underwater and harsh working environment, once underwater concrete defects occur, dams and channels will leak , posing a direct hazard to the safe operation of the dam, resulting in a large amount of water loss from the channel. But due to operational requirements, many defective dams and channels do not allow water to be vented for repair, requiring underwater construction. For large-scale anti-seepage treatment under deep water conditions, materials and processes are a big problem. Therefore, the study o...
