  • Patent number: 12247143
    Abstract: A two-stage epoxy bonding oil includes a main agent A and a curing agent B in a weight ratio of 1:1 to 3:1. The curing agent B includes 70 to 90 parts of a linear bifunctional secondary amine curing agent, 10 to 30 parts of a high-melting-point latent curing agent and 1 to 5 parts of an anti-settling agent. A two-stage curing of epoxy bonding oil includes a first-stage curing at room temperature whereby the cured product is in a thermoplastic state and a second-stage curing at 100° C. to 180° C. whereby the cured product is in a thermosetting state. It solves the contradiction between sticking wheels and bonding performance of the bonding layer in field of road and bridge pavement, exploring a new direction for the waterproof bonding layer materials in road and bridge pavement such as steel bridge deck pavement, concrete bridge deck pavement and tunnel pavement.
