Cut into granules with a particle size of 3 mm to obtain the anti-shedding agent. The distribution ratio of each group is shown in Table 1.

Embodiment 3

[0055] The SBR with a bound styrene content of 39wt% was pulverized in advance, with a particle size of 5-17 mm, and set aside. Warm up the kneader and set aside.

[0056] Weigh 58 kg of pulverized SBR, 48 kg of polyethylene oxide with a molecular weight of 3.9 million, 17 kg of styrenated phenol, 78 kg of polyester resin, 38 kg of octadecyltrimethylammonium chloride, 2,5-bis 29 kg of amino-4,6-dihydroxypyrimidine hydrochloride was placed in a kneader for mixing at a temperature of 190°C for 110 minutes; then extruded to granulate at a temperature of 175°C. Cut into granules with a particle size of 4 mm to obtain the anti-shedding agent. The distribution ratio of each group is shown in Table 1.

Abstract

The invention discloses an anti-shedding agent as well as a preparation method and application thereof. The anti-shedding agent comprises the following raw materials: styrene butadiene rubber, polyethylene oxide, styrenated phenol, resin, alkyl ammonium chloride and a nitrogen-containing aromatic compound. The preparation method of the anti-shedding agent comprises the following steps: uniformly mixing the materials, mixing, extruding and granulating to obtain the anti-shedding agent. The anti-shedding agent disclosed by the invention is granular, is used in airport asphalt, can remarkably improve the adhesion strength of the asphalt and improve the anti-shedding 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, and in particular relates to an anti-shedding 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, i...
