Document Type and Number:
Japanese Patent JP7475743
Kind Code:
B2
Abstract:
The present disclosure discloses an economical epoxy resin material for epoxy asphalt with low-temperature resistance and high flexibility as well as a preparation method thereof. The material comprises 60 parts of an epoxy resin main agent, 0.4 parts to 1.6 parts of a modifying agent, 31 parts to 36.5 parts of an active curing agent, 0.5 parts to 1.5 parts of a titanate coupling agent, and 1.6 parts to 6.4 parts of a reversible deformation additive. The epoxy resin material in the present disclosure has good compatibility with asphalt, can be fully crosslinked in the asphalt to form a network structure, and the synthesized epoxy asphalt has excellent flexibility and long retention time in a low-temperature environment; meanwhile, the epoxy resin system adopts China-made epoxy resin, the price of the used curing agent material is low, and the economy is far superior to that of other high-property epoxy resin system materials on the market. The economic epoxy resin system for epoxy asphalt with low-temperature resistance and high flexibility has excellent properties and a relatively low cost, and is suitable for preparing epoxy asphalt for paving high-grade highway pavements, concrete bridge pavements and steel bridge pavements.
