Utilization and Properties of Modified Epoxy Resin for Colorful Anti-Slip Pavements

The performance of the bonding materials of colorful anti-slip pavements is a critical factor influencing their service life. To obtain a bonding material with good flexibility and durability, TDI-polyether polyurethane prepolymer modified epoxy resin (TDI-PUP-M-ER) was prepared. The basic performances of TDI-PUP-M-ER were studied. The optimal amount of TDI-polyether polyurethane prepolymer (TDI-PUP) and preferred curing agents for the TDI-PUP-M-ER were determined. Furthermore, the durability of the TDI-PUP-M-ER bonding material was systematically evaluated. The results showed that the flexibility and mechanical strength of the epoxy resin are considerably improved by adding TDI-PUP. When the content of TDI-PUP in epoxy resin was 10%, compared with the pure epoxy resin, the tensile strength of TDI-PUP-M-ER was improved by 52.8%, its elongation at break by 112%, its bending strength by 21.6%, and its bending deformation by 61.1%. After corrosion condition, the final mass loss rate of the resin was only 0.69–1.08 mg/g, showing that the TDI-PUP-M-ER bonding material exhibits good durability.
