Embodiment 1

[0043] The SBR with a combined styrene content of 23wt% was pulverized in advance, with a particle size of 5-19mm, and set aside. Warm up the kneader and set aside.

[0044] Weigh 2.0kg of pulverized SBR, 2.0kg of triphenylmethane triisocyanate, 2.0kg of N,N'-diphenyl-p-phenylenediamine, 1.0kg of silane coupling agent (KH560), and 3.0kg of four-line extraction oil Put it in a kneader for kneading, the kneading temperature is 130°C, and the kneading time is 60min; then extrude, the extrusion temperature is 110°C to obtain a pasty anti-stripping agent. The distribution ratio of each group is shown in Table 1.

Embodiment 2

[0046] The SBR with a combined styrene content of 45wt% was pulverized in advance, with a particle size of 5-15mm, and set aside. Warm up the kneader and set aside.

[0047] Weigh 13.0kg of pulverized SBR, 8.0kg of triphenylmethane triisocyanate, 7.0kg of N-cyclohexyl-N'-phenyl-p-phenylenediamine, and 6.0kg of aluminate coupling agent in a kneader for mixing. Refining, while mixing, add furfural to refine the extracted oil, add in portions, add 5.0kg every 5 minutes, until the added amount reaches 25.0kg, continue to mix, the mixing temperature is 160°C, and refine from 25.0kg of furfural After the extraction oil is completely added, the mixing time is 90 minutes; then extrusion, the extrusion temperature is 140°C. A thick paste is formed after extrusion, resulting in an anti-stripping agent. The distribution ratio of each group is shown in Table 1.

Embodiment 3

[0049] The SBR with a combined styrene content of 34wt% was pulverized in advance, with a particle size of 5-16 mm, and set aside. Warm up the kneader and set aside.

[0050] Weigh 3.2 kg of pulverized SBR, 3.2 kg of triphenylmethane triisocyanate, 3.2 kg of N-phenyl-N'-isopropyl-p-phenylenediamine, and 2.2 kg of silane coupling agent (KH570) and place them in a kneader Carry out mixing inside, add catalytic cracking oil slurry while mixing, add in two times, add 2.4kg every 5 minutes, until the addition amount of catalytic cracking oil slurry reaches 4.8kg, continue mixing, mixing temperature is 135 °C, counting from the time when 4.8kg of catalytic cracking oil slurry is completely added, the mixing time is 65 minutes; then extrude at a temperature of 115 °C to obtain a pasty anti-stripping agent. The distribution ratio of each group is shown in Table 1.

Abstract

The invention discloses an anti-stripping agent as well as a preparation method and application thereof. The anti-stripping agent comprises the following raw materials: styrene butadiene rubber, triphenylmethane triisocyanate, a p-phenylenediamine compound, a coupling agent and aromatic oil. The preparation method comprises the following steps: uniformly mixing the materials, mixing and extruding to obtain the anti-stripping agent. The asphalt anti-stripping agent is pasty and does not need to be cured in the using process, the production time of anti-stripping asphalt is shortened, and the working efficiency is improved. The anti-stripping agent disclosed by the invention is used in airport asphalt, can remarkably improve the adhesion strength of the asphalt and improve the anti-stripping performance, and has relatively strong adaptive capacity to a high-temperature wake flow environment of an airplane.

Description

technical field [0001] The invention belongs to the field of petroleum industry and basic material chemistry, in particular to an asphalt anti-stripping agent and a preparation method thereof, and is especially suitable for airport asphalt runways. Background technique [0002] The highest temperature of the airflow ejected by modern jet aircraft engines can reach 850°C-900°C, and the airflow speed can reach 180m / s, which spreads to the airport runway in an elliptical shape, and the surface temperature of the road surface rises rapidly, causing damage to the asphalt pavement . The measured data shows that when the summer temperature is 40°C, the maximum temperature of the asphalt pavement reaches 140°C due to the influence of the high-temperature wake of the aircraft. Therefore, in order to avoid damage to the pavement, anti-blow pads are installed at the ends of the runways of civil airports to provide sufficient preparation time for aircraft during takeoff. However, it i...
