[0002] Solar power generation pavement is a road surface that can convert solar energy into electrical energy. As for the top of the pavement subgrade, it is composed of multiple pavement modules electrically connected, and finally connected to the grid to realize photovoltaic power generation; the solar power generation pavement module and the cement concrete or Adhesive materials are required for bonding between asphalt concrete and between the various structural layers of the solar power generation surface module. In the prior art, the structural layer bonding materials with multiple bases mostly use epoxy resin-based adhesives, epoxy resin It is widely used as an adhesive in the field of construction and other fields after being cured and cross-linked under the action of a curing agent. However, epoxy resin-based adhesives have some inherent defects, including hard and brittle after curing, and are not aging-resistant for outdoor use. , Long-term use in a vibration environment is prone to cracks, breakage and loss of bonding effect; in addition, when it is applied to solar power generation surfaces, the temperature shrinkage performance of epoxy resin-based adhesives is different from that of solar power generation surfaces, asphalt concrete, and cement concrete. There are obvious differences, which will cause a series of problems that directly affect the quality of the project.
