Abstract

The invention belongs to the technical field of asphalt materials, and relates to bio-based flame-retardant modified asphalt and a preparation method thereof. The bio-based flame-retardant modified asphalt comprises 100 parts of hard asphalt, 0.5-5 parts of a warm mixing agent, 1-5 parts of a plasticizer, 1-5 parts of a stabilizer, 1-50 parts of modified plant asphalt, 1-5 parts of an antiaging agent and 1-20 parts of a microcapsule flame retardant. Compared with the prior art, the bio-based flame-retardant modified asphalt has the advantages as follows: with the hard asphalt and the bio-basedplant asphalt as raw materials, own advantages of the hard asphalt and the bio-based plant asphalt are fully combined to form a combined effect of softness and hardness; meanwhile, supplemented by additives and modifying measures for making up own defects, bio-based modified asphalt with excellent performance is finally prepared; meanwhile, through addition of the microcapsule flame retardant, the bio-based flame-retardant modified asphalt has flame-retardant and smoke-suppressing functions. In the preparation process, used materials are environmentally friendly, wastes are turned into treasures, and the obtained flame-retardant modified asphalt not only has various excellent performance, but also can achieve flame retardance and smoke suppression, and is of great advantage to reducing casualties and material loss in a fire disaster.

Description

technical field

[0001] The invention belongs to the technical field of asphalt materials, and in particular relates to a bio-based flame-retardant modified asphalt and a preparation method thereof. Background technique

[0002] With the vigorous development of my country's transportation industry and the continuous improvement of infrastructure, the problems of energy shortage and environmental pollution have become increasingly prominent. Petroleum bitumen is a product of the crude oil processing process, which is the residue after crude oil distillation. Due to its own properties, it is widely used in road paving and construction fields, and the global demand for bitumen remains high. According to the latest report of "Transparency Market Research" in the United States, the global demand for asphalt is expected to reach 121.99 million tons in 2018, with a compound annual growth rate of 2.3% from 2012 to 2018. As the pace of development accelerates, the defects of asphalt ...
