Abstract

Disclosed are concrete channel permeability-reducing agent and a preparation method and purpose thereof. The concrete channel permeability-reducing agent comprises, by weight, 40-50 parts of etherified starch (at least 90% of solid content), 30-50 parts of fluorosilicon resin (at least 90% of solid content), 80-100 parts of waterborne fluorocarbon emulsion (48% of solid content), 10-15 parts of methylene dimethyl binaphthol sulfonate polymer (at least 90% of solid content), and 300-350 parts of water. The fluorosilicon resin is synthetic resin formed by mixing fluorine resin and organic silicon resin. The waterborne fluorocarbon emulsion is copolymer of vinyl fluoride and hydroxyl vinyl ether, wherein concentration percentage by weight of fluorine is 8-11.5%, and a main chain contains fluorine atom. The concrete channel permeability-reducing agent is economical in formula, fine in permeability-reducing effect, and long-lasting in function. The preparation method of the concrete channel permeability-reducing agent includes mixing and ultrasonic dispersing. The purpose of the concrete channel permeability-reducing agent is to form a permeability-reducing film on the surface of the concreted channel by roller coating, brush coating or spay coating the permeability-reducing agent on the surface of the concreted channel. By the permeability-reducing film, fine permeability-reducingeffect of the concrete channel can be achieved.

Description

technical field [0001] The invention relates to an anti-seepage agent, more specifically, the invention relates to a concrete channel anti-seepage agent, and at the same time, the invention also relates to a preparation method and application of the concrete channel anti-seepage agent. technical background [0002] At present, there are a large number of various concrete channels in the construction of water conservancy projects in my country (such as reservoir dams, river and lake embankments) and water sewage discharge. played a crucial role. However, the anti-seepage effect of the concrete channel is poor and the leakage is serious. According to the investigation, it is found that the amount of water seepage from canals accounts for the vast majority of the water loss in the canal system, and under normal circumstances, the amount of water seepage from canals accounts for 30-60% of the diversion water at the head of the canal. The water loss of the canal system not only ...
