Abstract

The invention discloses high-toughness waste rubber asphalt. The high-toughness waste rubber asphalt comprises substrate asphalt, waste rubber powder, an activating agent, a nanometer toughening agent and a crosslinking agent. A preparation method of the high-toughness waste rubber asphalt comprises the following steps: heating the substrate asphalt for melting, adding the waste rubber powder, the activating agent, the nanometer toughening agent and the crosslinking agent in sequence, mixing and uniformly stirring to obtain an asphalt mixture; and performing the process treatment of high-speed colloid milling, high-speed shearing, crosslinking reaction, stability development and the like on the asphalt mixture in sequence to obtain the high-toughness waste rubber asphalt. The high-toughness waste rubber asphalt has the advantages of reasonable preparation process, low product price, lower storage temperature than products of the same type, aging resistance, high bonding performance and high low-temperature crack resistance, and the defect of limitation on the toughness of conventional modified asphalt used in a low-temperature environment is overcome.

Description

technical field

[0001] The invention relates to a rubber asphalt and a preparation method thereof, in particular to a high-toughness waste rubber asphalt and a preparation method thereof. Background technique

[0002] With my country's economic development, the automobile industry has also developed rapidly, and the output of waste rubber has increased sharply. By 2013, the number of waste tires in China has reached more than 300 million, with a total weight of about 15 million tons. The resource utilization of waste tires has already become a problem that the Chinese government needs to solve. On the one hand, discarded tires pollute the environment, but they are also valuable resources. , plus rubber hoses, tapes, rubber shoes and other rubber products, the waste rubber produced every year exceeds 20 million tons. At present, the recycling and comprehensive utilization of waste rubber is mainly incineration to generate heat and produce recycled rubber. Incineration and he...
