The invention discloses biological epoxy asphalt. The biological epoxy asphalt contains a component A, a component B and a component C, wherein the component A contains epoxidized soybean oil and a diluent, the component B contains a curing agent, an accelerant and a defoaming agent, and the component C contains asphalt; and the mass ratio of the component A to the component C is (105-126) :45, and the mass ratio of the component A to the component B is 100 : (57-520). Compared with the prior art, the biological epoxy asphalt can be used for replacing traditional petroleum asphalt; by utilizing the materials of epoxidized soybean oil, a biological curing agent and the like, the cost is remarkably lowered, and meanwhile, the thermoplastic property of a traditional asphalt material can be effectively improved, so that the biological epoxy asphalt has excellent high-low-temperature performance and anti-aging property and can be widely applied to the pavements of roads, tunnels and the like and the pavement of bridge surfaces. The invention discloses a preparation method of the biological epoxy asphalt.
Description
technical field [0001] The invention belongs to the field of construction, and in particular relates to a biological epoxy asphalt and its preparation method and application. Background technique [0002] Epoxy asphalt is a three-dimensional continuous phase thermosetting material formed by an irreversible chemical crosslinking and curing reaction of epoxy resin, curing agent, and petroleum asphalt. As the temperature rises, epoxy asphalt will not soften like traditional asphalt, and has good aging resistance and chemical corrosion resistance. The fatigue performance of epoxy asphalt concrete is three orders of magnitude greater than that of Superpave polymer modified asphalt concrete, which can be easily It is suitable for heavy load, large traffic volume and wide-area temperature, which greatly improves road performance. On the other hand, as an alternative product of traditional petroleum asphalt, bio-asphalt can be made from a variety of biomass materials, such as wheat...
