Economical low-temperature-resistant high-flexibility epoxy resin material for epoxy asphalt and preparation method thereof

The invention discloses an epoxy resin material for economical low-temperature-resistant high-flexibility epoxy asphalt and a preparation method of the epoxy resin material. The epoxy resin material comprises 60 parts of an epoxy resin main agent, 0.4-1.6 parts of a modifier, 31-36.5 parts of an activated curing agent, 0.5-1.5 parts of a titanate coupling agent and 1.6-6.4 parts of a reversible deformation additive. The epoxy resin material disclosed by the invention has good compatibility with asphalt and can be fully crosslinked in the asphalt to form a net structure, and the synthesized epoxy asphalt shows excellent flexibility in a low-temperature environment and is long in holding time; meanwhile, the epoxy resin system adopts domestic epoxy resin, the used curing agent material is low in price, and the economical efficiency is far better than that of other high-performance epoxy resin system materials on the market. The epoxy resin system for the economical low-temperature-resistant high-flexibility epo
