Problems solved by technology

[0002] Because thermosetting plastics form a cross-linked structure after curing and molding, they cannot be melted and molded again, so recycling is difficult and the environment is seriously polluted
However, the amount of thermosetting plastics is extremely large, and the current recovery rate is less than 10%, resulting in a great waste of resources
[0003] With the rapid development of my country's highway industry, the demand and consumption of raw materials such as asphalt and mineral materials have greatly increased. In response to the national call for energy conservation and emission reduction, waste materials such as waste tire rubber powder and waste thermoplastics are used in the asphalt industry. , and achieved good results, especially for waste tire rubber, but the application for huge waste plastics is still relatively rare

Abstract

The invention relates to waste thermosetting plastic modified asphalt and a preparation method thereof. The modified asphalt is prepared from, by weight, 100 parts of matrix asphalt, 20-40 parts of waste thermosetting plastic, 1-5 parts of modifying agent, 0.1-0.2 part of foaming agent, 0.2-0.5 part of foam stabilizer, 0.1-0.2 part of antifoaming agent, 0.05-0.1 part of stabilizer, 10-20 parts ofvinyltriethoxysilane and 30-50 parts of water. According to the waste thermosetting plastic modified asphalt, by adding vinyltriethoxysilane, the matrix asphalt and the waste thermosetting plastic arecompactly combined through a coupling effect of vinyltriethoxysilane, and the viscosity and compactness of the asphalt are improved; in the preparation process, firstly, the foaming agent is added, the modified asphalt is foamed, the internal structure of the modified asphalt is temporarily turned into a honeycomb shape, the structure is more stereoscopic, the internal connection is more uniformand compact, the matrix asphalt and the waste thermosetting plastic are compactly combined, the formed structure is treated by the antifoaming agent, the formed connection structure is extruded and ismore compact, the viscosity and connectivity are greatly improved accordingly, and fracture is effectively prevented.

Description

technical field [0001] The invention relates to the field of asphalt preparation, in particular to a waste thermosetting plastic modified asphalt and a preparation method thereof. Background technique [0002] Since thermosetting plastics form a cross-linked structure after solidification and molding, they cannot be melted and molded again, so recycling is difficult and the environment is seriously polluted. However, the amount of thermosetting plastics is extremely large, and the current recovery rate is less than 10%, resulting in a great waste of resources. [0003] With the rapid development of my country's highway industry, the demand and consumption of raw materials such as asphalt and mineral materials have greatly increased.
