preparation example Construction

[0032] A kind of preparation method of light-colored asphalt of the present invention, as attached figure 1 As shown, the specific steps are as follows:

[0033] step one

[0034] Sequentially weigh 21-23 parts of petroleum refining products, 53-56 parts of copolymerized petroleum resin, 4-6 parts of styrene-butadiene-styrene triblock copolymer, 15-16 parts of ethylene-vinyl acetate For the copolymer, add the above-mentioned components weighed into the reaction container in sequence, seal the reaction container and put it into an oven for heating, the heating temperature is 145°C-155°C, and the heating time is 3 hours;

[0035] step two

[0036] After the above-mentioned step one heating is completed, take out the reaction vessel from the oven, then open the reaction vessel, place it under a high-speed shearing instrument for shearing, the rotating speed of the high-speed shearing instrument is 6000r / min, and the shearing time is 1 hour. During shearing, heating equipment s...

Embodiment 1

[0069] step one

[0070] Weigh 21 parts of petroleum refining products, 53 parts of copolymerized petroleum resin, 4 parts of styrene-butadiene-styrene triblock copolymer, and 15 parts of ethylene-vinyl acetate copolymer in sequence. Add the above ingredients into the reaction container in sequence, seal the reaction container and put it into an oven for heating, the heating temperature is 145°C, and the heating time is 3 hours;

[0071] step two

[0072] After the above-mentioned step one heating is completed, take out the reaction vessel from the oven, then open the reaction vessel, place it under a high-speed shearing instrument for shearing, the speed of the high-speed shearing instrument is 6000r / min, and the shearing time is 1 hour. During shearing, heating equipment such as an electric furnace is used to control the temperature of the reaction vessel so that the temperature of the reaction vessel is 155°C;

[0073] step three

[0074] After the above-mentioned step 2...

Embodiment 2

[0078] step one

[0079] Weigh in turn 22 parts of petroleum refining products, 54.5 parts of copolymerized petroleum resin, 5 parts of styrene-butadiene-styrene triblock copolymer, and 15.5 parts of ethylene-vinyl acetate copolymer. Add the above ingredients into the reaction container in turn, seal the reaction container and put it into an oven for heating, the heating temperature is 150°C, and the heating time is 3 hours;

[0080] step two

[0081] After the above-mentioned step one heating is completed, take out the reaction vessel from the oven, then open the reaction vessel, place it under a high-speed shearing instrument for shearing, the speed of the high-speed shearing instrument is 6000r / min, and the shearing time is 1 hour. During shearing, heating equipment such as an electric furnace is used to control the temperature of the reaction vessel so that the temperature of the reaction vessel is 160°C;

[0082] step three

[0083] After the above step 2 is completed,...

Abstract

The invention discloses a light-colored asphalt and a preparation method thereof. The light-colored asphalt is prepared from the following components by mass: 21-23 parts of petroleum refining products, 53-56 parts of copolymerized petroleum resin, The content of styrene-butadiene-styrene triblock copolymer is 4-6 parts, and the content of ethylene-vinyl acetate copolymer is 15-16 parts. The beneficial effect of the present invention is that the production cost of light-colored asphalt is reduced, and the light-colored asphalt has good adhesion, high-temperature performance, and excellent adhesion performance; it has excellent adhesion performance and relatively large cohesive force, which greatly improves the Anti-erosion and anti-stripping ability of asphalt mixture; color asphalt can be prepared after adding pigments.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, relates to a light-colored asphalt, and also relates to a preparation method of the light-colored asphalt. Background technique [0002] With the rapid development of society in recent years, many places have begun to build colored roads. Compared with ordinary black asphalt pavement, colored asphalt pavement of different colors not only has the characteristics of bright colors and beautification of the environment, but also can improve the visibility of the road surface, guide the orderly flow of traffic, reduce the occurrence of traffic accidents, and play an important role in organizing urban traffic. play a positive role. [0003] Light-colored asphalt is the basis for preparing colored asphalt and light-colored emulsified asphalt. [0004] There are two main sources of light-colored asphalt: one is to use conventional black asphalt, and use special technology to remove asphalte...
