Embodiment Construction
[0013] The present invention is further described as follows in conjunction with specific examples:
[0014] A steel bridge deck pavement interface adhesive is a bonding material for the steel bridge deck and the upper pavement layer. It is composed of A group material and B group material in a weight ratio of A: B = 5: 2.
[0015] The components and weight percentages of group A materials are:
[0016] Bisphenol A type epoxy resin CYD-128 90%
[0017] Phenol Novolak Epoxy Resin 10%
[0018] The components and weight percentages of group B materials are:
[0019] Polyamide 650 50%
[0020] Polysulfide rubber 18%
[0021] Amine curing agent T31 30%
[0022] Coupling agent KH-550 2%
[0023] In group A, phenol novolac epoxy resin is introduced into bisphenol A epoxy resin CYD-128 to increase the density of benzene rings per unit volume of the system, thereby improving the temperature resistance of the cured product system.
[0024] In group B, since polyamide 650 is forme...
