Reactive normal-temperature cold patch cementing material and preparation method thereof

The invention discloses a reactive normal-temperature cold patch cementing material, which comprises the following components in parts by weight: 100 parts of BC-1 type cationic slow-breaking emulsified asphalt, 5-20 parts of non-ionic waterborne epoxy emulsion, 2-7 parts of a fatty amine addition type curing agent and 1-6 parts of SBR styrene-butadiene latex asphalt modifier, wherein the non-ionic waterborne epoxy emulsion is prepared from a non-ionic compound emulsifier and a bisphenol A epoxy resin, and the nonionic composite emulsifier is composed of 100 parts of a bisphenol A epoxy resin,40 parts of ethylene glycol monobutyl ether, 16 parts of diethanol amine, 214 parts of polyethylene glycol 600, 6 parts of N,N-dimethylethanolamine and 16 parts of bromoethane. The reactive normal-temperature cold-patch cementing material and the preparation method thereof have the beneficial technical effects that the reactive normal-temperature cold-patch cementing material is used for preparing the reactive normal-tem
