Benefits of technology

This patented technology describes how graphynes are used for treatments with bituminous mixtures that contain volatile substance such as hydrocarbons or other compounds like methane gas (CH4). By modifying them chemically, these compositions may be more effective at reducing malodors caused during production processes compared to traditional methods without adding any chemical agents. Additionally, this modified layered graphite also helps reduce degradation over time due to factors like UV light exposure. Overall, this new method allows for better control and optimization of asphaltic mixings while maintaining their quality level.

Problems solved by technology

This patented technical problem addressed in this patents relating to improving the quality of shale oil used as raw material for producing environmentally friendly materials like paints or coatings that are resistant to damage caused from various factors including harmful gasses released when mixed with other substances.

Abstract

The invention discloses an odorless asphalt mixture, a preparation method thereof and an application of the odorless asphalt mixture on a pavement, and the preparation method comprises the following steps: carrying out low-temperature plasma modification on a graphdiyne nano material to obtain a graphdiyne modified solution; mixing 1-10 parts by weight of magnesium hydroxide, 1-2 parts by weight of TEOS, 1-5 parts by weight of vegetable oil, 1-10 parts by weight of SBS and 1-2 parts by weight of an odor inhibitor to obtain an asphalt composite modifier; heating the matrix asphalt to 150 to 170DEG C; then adding an asphalt composite modifier and graphdiyne modification liquid; wherein the weight ratio of the matrix asphalt to the asphalt composite modifier to the graphdiyne modification liquid is 100: (1-5): (10-25), shearing and heating to 185-220 DEG C, shearing and swelling for 0.5-2 hours, then cooling to 170-180 DEG C to obtain the odorless asphalt mixture, drying and packaging toobtain the odorless asphalt mixture. By selecting a novel nano material graphdiyne, compared with traditional materials such as graphene and carbon nanotubes, the optimization efficiency of the performance of the odorless asphalt is higher.
