A material emergency repair system

Abstract

The invention discloses an emergency material repair system, comprising a first liquid storage tank, a second liquid storage tank and a to-be-repaired material, wherein the to-be-repaired material is internally provided with a continuous channel; the upper part of the first liquid storage tank is communicated with a first gas push device, and the lower part of the first liquid storage tank is communicated with one end of the continuous channel of the to-be-repaired material; the upper end of the second liquid storage tank is communicated with the first gas push device, and the lower part of the second liquid storage tank is communicated with the other end of the continuous channel of the to-be-repaired material, so that a closed communicating system is formed; the first liquid storage tank is internally filled with a DCPD solution; the second liquid storage tank is internally filled with a dichloromethane solution containing a catalyst; the first gas push device and a second gas transmission device are internally filled with adjustment gas, and the adjustment gas is used for adjusting and controlling the gas pressure in the closed communicating system to be higher than the standard atmospheric pressure. The emergency material repair system has the advantages of being immediate in repair, large in area, high in efficiency and low in cost, thus having an important actual application value.

Description

technical field [0001] The invention belongs to the technical field of material repair, and in particular relates to a material emergency repair system based on the fast curing reaction of dicyclopentadiene (DCPD). Background technique [0002] With the development of science and technology, we have higher and higher requirements for materials in many fields, and traditional materials are prone to leakage and other accidents after being impacted, which will eventually have an incalculable impact on the devices themselves. Especially in special fields such as navigation and aviation, once an accident such as impact and leakage occurs, it will cause a major threat to personal and property. Therefore, it is of great practical significance to explore an emergency material self-repair system. [0003] The metal carbene catalyst has high reactivity, and when it is mixed with DCPD, it can produce a relatively rapid reaction. Whether it is a system based on the rapid reaction betwe...

AI Technical Summary

Problems solved by technology

The repair system formed in this way has a series of defects such as complicated synthesis of microcapsules, time-consuming, a lot of waste of catalysts, high cost, large mechanical properties of the material itself, and too small repair range, which is not conducive to large-scale use in production and life.
