Embodiment 1

[0033] (1) Preheat part of the compatibilizer to 140°C in the reaction kettle, then add petroleum resin, stir to make the compatibilizer and petroleum resin form a uniform and stable first mixture, the temperature during stirring is 120°C, and the time is 40min. Then raise the temperature of the first mixture to 170°C, then gradually add the polymer to the first mixture, stir continuously to make it fully swell and mix evenly, the swelling temperature is 170°C, and the time is 40min, and then the mixture is passed through a colloid mill Prepare a homogeneous system by shearing, add vulcanizing agent, anti-aging agent, and activator to the homogeneous system, stir until the reaction is complete, the stirring temperature is 170°C, and the stirring time is 5h, then stop heating the system to obtain the second mixture;

[0034] (2) Heat the remaining compatibilizer to 70°C in another reactor, then add viscosity reducer 1 and viscosity reducer 2, and keep stirring for 30 minutes to...

Embodiment 2

[0040](1) Take part of the compatibilizer and preheat it to 140°C in the reaction kettle, then add petroleum resin, stir to make the compatibilizer and petroleum resin form a uniform and stable first mixture, the temperature during stirring is 140°C, and the time is 30min . Then raise the temperature of the first mixture to 170°C, then gradually add the polymer to the first mixture, stir continuously to make it fully swell and mix evenly, the swelling temperature is 170°C, and the time is 40min, and then the mixture is passed through a colloid mill Prepare a homogeneous system by shearing, add vulcanizing agent, anti-aging agent, activator 1 and activator 2 to the homogeneous system, stir until the reaction is complete, the temperature of stirring is 170°C, the time is 6h, and then stop heating the system, obtain the second mixture;

[0041] (2) Heat the rest of the compatibilizer to 80°C in another reactor, then add viscosity reducer 1 and viscosity reducer 2, and keep stirr...

Embodiment 3

[0047] (1) Take compatibilizer 1 and preheat it to 130°C in the reaction kettle, then add petroleum resin 1 and petroleum resin 2, stir to make the compatibilizer and petroleum resin form a uniform and stable first mixture, and the temperature during stirring is 110 ℃, the time is 40min. Then raise the temperature of the first mixture to 175°C, gradually add polymer 1 and polymer 2 into the first mixture, stir continuously to make it fully swell and mix evenly, the swelling temperature is 175°C, and the time is 30min, and then The mixture is sheared by a colloid mill to prepare a homogeneous system. Add vulcanizing agent, anti-aging agent, activator 1 and activator 2 to the homogeneous system, and stir until the reaction is complete. The temperature of stirring is 175°C, the time is 4h, and then stop heating the system to obtain a second mixture;

[0048] (2) Heat compatibilizer 2 to 70°C in another reaction kettle, then add viscosity reducer 1 and viscosity reducer 2, and ke...

Abstract

The invention discloses a repairing material for a color asphalt pavement, and a preparation method thereof, wherein the repairing material comprises, by mass, 10-22% of a petroleum resin, 35-50% of acompatibilizer, 2-9% of a polymer, 15-50% of a viscosity reducing agent, 0.05-1.0% of a vulcanizing agent, 0.1-1.5% of an anti-aging agent, and 0.05-1.0% of an activator. According to the present invention, the repairing material has advantages of excellent high-temperature performance, excellent low-temperature performance, good stability, high softening point, strong adhesion, high low-temperature elongation rate and high low-temperature ductility, can be stored at room temperature for more than one year, and can be well mixed with color pigments at a room temperature so as to effectively repair the color asphalt pavement with small-area damage after the mixing.

Description

technical field [0001] The invention relates to a patching material and a preparation method thereof, in particular to a patching material for colored asphalt pavement patching and a preparation method thereof. Background technique [0002] Colored asphalt pavement improves the black monotony of ordinary asphalt pavement, can match and coordinate with surrounding buildings and landscapes, and has obvious landscape effects. As a paving material with beautifying environment, colored asphalt has entered the stage of experimentation and promotion. Many cities have tried to use colored asphalt concrete to pave urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. In addition, the role of colored asphalt in traffic organization and management has been paid more and more attention. Different colors of asphalt pavement can improve the recognition effect of the driver, and can also make the driver's attention more concentrated, thereby playing the role of i...
