Abstract

The quick leak blocking glue consists of two components, including glue liquid and composition curing agent, in the weight ratio of 65-90 to 10-35; or consists of epoxy resin, isocyanate and their pre-polymer, polyol, KH series of silane coupling agent, curing promoter and catalyst. When used, the two components are mixed and mixture is applied in the leakage to cure and block in 10-30 sec. The quick leak blocking glue may be used in blocking leakage of flange, valve, etc. in dangerous chemical storage, reactor and pipeline, and the operation may be completed by one robot. The present invention has the advantages of simple glue compounding and fast curing.

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...
