Embodiment 1

[0031] The asphalt anti-aging agent mentioned in this example is composed of the following raw materials in parts by weight:

[0032]

[0033] The stabilizer is light stabilizer UV-770.

[0034] Preparation:

[0035] a. Mix quercetin, lignin, stabilizer and sodium xanthate evenly for later use;

[0036] b. Put the aromatic oil in an oven and heat it to 160°C and take it out. Add the well-mixed mixture of quercetin and lignin into the aromatic oil, stir with a stirring rod, and take out the stirring rod when roughly mixing. Put the mixed aromatic oil into the electric heating mantle, set the temperature of the electric heating mantle to 160°C, and insert the sensor into the cup wall. Place the rotor of the shearing instrument in the aromatic oil, adjust the position of the rotor so that there is a certain gap between the rotor and the cup wall and the bottom of the cup, open the shear switch to ensure that the aromatic oil does not spill out of the container. 1000r / min re...

Abstract

The invention relates to an asphalt anti-aging agent, which comprises the following components in percentage by weight: 3 to 10 percent of quercetin, 10 to 15 percent of stabilizer, 40 to 70 percent of aromatic hydrocarbon oil, 10 to 30 percent of lignin and 10 to 15 percent of sodium xanthate. The sum of the weight percentages of the quercetin, the stabilizer, the aromatic oil, the lignin and the sodium xanthate is 100%, and the asphalt anti-aging agent is formed by uniformly mixing the sodium xanthate, the quercetin, the stabilizer, the aromatic oil, the lignin and the sodium xanthate. The asphalt anti-aging agent has the advantages of good ultraviolet aging resistance, no volatility and easiness in asphalt fusion, and can effectively solve the problem of serious ultraviolet aging of asphalt in the Qinghai-Tibet Plateau region.

Description

technical field [0001] The invention belongs to the field of anti-ultraviolet aging road asphalt, and particularly relates to an anti-aging agent for asphalt used in the Qinghai-Tibet Plateau region and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, the construction of high-grade highways in my country has developed rapidly, and asphalt pavement has been widely used due to its excellent performance. Compared with cement pavement, asphalt pavement has many advantages, such as driving comfort, low noise, and convenient maintenance. In my country's high-grade pavement construction, the proportion of asphalt pavement is as high as 90%. The designed service life of highway asphalt pavement is 15 to 20 years, but the actual service life is far below this figure. The annual maintenance cost of highways in my country is as high as 82.59 billion yuan. Improving the service life of asphalt pavement is an important direction of roa...
