Abstract

The rapid plugging adhesive used in hazardous environments belongs to the two-component leak plugging adhesive, and relates to a two-component room temperature rapid curing adhesive with epoxy resin and polyurethane as the main components, which is suitable for robot operation, and a preparation method. It overcomes the problems of high viscosity, cumbersome glue dispensing and inconvenient robot operation of the traditional quick plugging glue. The glue is composed of two-component glue (1) and composite curing agent (2), and the mass ratio of the two is 65-90:10-35, that is, epoxy resin, isocyanate and its prepolymer, polyol, KH series silane coupling agent, curing accelerator and catalyst composition. When using, mix (1) and (2) and plug in the leakage, and the leakage will be cured within 10-30 seconds. The glue can be used for rapid repair of leaks in hazardous chemical storage, reactors, pipe enamel, valves, etc. Without affecting normal operation, the leak can be completed by robots. advantage. The invention adds a new variety to the plugging glue.

Description

technical field [0001] The invention belongs to two-component leak-stopping glue, and relates to a two-component room-temperature fast-curing glue with epoxy resin and polyurethane as the main components and its preparation method, in particular to a kind of adhesive which is suitable for operation by robots and is used in dangerous chemical The invention discloses a glue for fast repairing leaks in product storage, reactors, pipeline enamel, valves, etc., and its use and preparation method. Background technique [0002] The rapid repair of hazardous chemical storage, reactor and pipeline leakage has always been a difficult problem in the chemical process. At home and abroad, there are many researches and developments on leak detection system and fast plugging glue. Due to the extreme danger brought by the leakage of hazardous chemicals and the people-oriented working idea, remote sensing detection by sensors and on-site repair systems by robots have been paid more and more...
