Colored asphalt and preparation method thereof

Abstract

The invention relates to asphalt and a preparation method thereof, and specifically relates to colored asphalt and a preparation method thereof. The colored asphalt comprises the components of, by weight: 30-50% of C5 petroleum resin, 30-55% of C9 petroleum resin, 5-30% of an inorganic pigment, 1-6% of a powdery styrene-butadiene rubber SBR modifying agent, 0.5-6% of a powdery thermoplastic styrene-butadiene rubber SBS modifying agent, and 5-20% of powdery solid rosin. According to the colored asphalt and the preparation method thereof provided by the invention, the colored asphalt is prepared into powdery solid or solid particles, and is directly added into a stirring tank and is mixed with heated graded stones with a certain temperature, such that colored asphalts with various colors can be directly produced, and road pavement and rolling constructions can be carried out. With the method, colored asphalt mixture preparation process is greatly simplified, and colored pavement construction is greatly simplified.

Description

technical field [0001] The invention relates to asphalt and its preparation process, in particular to a colored asphalt and its preparation method. Background technique [0002] With the improvement of people's living standards, new requirements have been put forward for the beauty of roads. At present, colored asphalt is mainly made of liquid decolorized asphalt, which becomes liquid and viscous at room temperature, and is packaged in iron drums or liquid large-scale transport special asphalt trucks. When in use, it needs to be removed from the drum and heated repeatedly. It is necessary to set up special drum removal equipment, storage tanks, heating equipment, pipeline equipment, etc., first heat the liquid viscous asphalt to remove the drum, then enter the storage tank, and then heat it. There are special pipelines For the production of colored asphalt mixture by pumping, the pigments need to be put in separately, which is very inconvenient to use, and repeated heating ...

AI Technical Summary

Problems solved by technology

[0003] 1. It requires special debarrel equipment or special asphalt truck for liquid large-scale transportation, which consumes a lot of energy and requires a long production time;

[0004] 2. Special colored asphalt storage equipment is required. Repeated heating is required during the production process, and a large amount of liquid colored asphalt will remain in the pipeline, which will cause serious aging, heavy pollution, and high energy consumption, which will reduce the mechanical properties of the colored asphalt mixture;

[0005] 3. Special pipelines are required, and other black asphalt mixtures cannot be produced, and they cannot be polluted and increase costs;

[0006] 4. The pigment needs to be put in separately, and the preparation process is more complicated
