Graphene modified anti-stripping agent and high-heat-dissipation graphene composite modified asphalt

Abstract

The invention discloses a graphene modified anti-stripping agent and high-heat-dissipation graphene composite modified asphalt. The graphene modified anti-stripping agent is prepared from 0.1-1 part of graphene, 0.1-1 part of carbon nanotubes, 0.3-5 parts of porous activated carbon, 0.1-1 part of mahogany petroleum sulfonate, 1-5 parts of sulfur and 90-100 parts of an anti-stripping agent; the high-heat-dissipation graphene composite modified asphalt comprises 20-30 parts of waste tire powder, 0.1-1 part of graphene powder, 0.1-1 part of carbon nanotubes, 0.3-5 parts of porous activated carbon, 2-5 parts of a graphene modified asphalt anti-stripping agent, 60-70 parts of petroleum asphalt, 1-3 parts of a stabilizer, 1-3 parts of sulfur, 0.5-1 part of mahogany petroleum sulfonate and 1-3 parts of metal oxide. Graphene carbon atoms have excellent Young modulus, high specific surface area, intrinsic strength and thermal conductivity; the porous activated carbon with high specific surface area has a strong adsorption function; the high modulus and the high strength of the carbon nanotubes make the modified asphalt have good toughness, and the added graphene modified anti-stripping agent can significantly improve the softening point, toughness and heat-conducting property of the asphalt.

Description

technical field [0001] The invention relates to the field of petroleum asphalt modification, in particular to a graphene modified anti-stripping agent and high heat dissipation graphene composite modified asphalt. Background technique [0002] According to the needs of social development, the traffic volume is increasing, the demand for traffic roads is increasing, and the climate is getting hotter and hotter, and the requirements for asphalt pavement are getting higher and higher, so as to improve the high temperature stability, low temperature crack resistance, softening point and Thermal conductivity, and extending service life, etc. are imminent. At present, it is difficult for ordinary asphalt to meet the requirements, and then some modified asphalts appear, most of which are modified by SBS. The cost of SBS modified asphalt is high. When asphalt concrete is mixed, the temperature needs to be raised, which increases energy consumption. [0003] Graphene is a new materi...
