preparation example Construction

[0035] The second aspect of the present invention provides the preparation method of the reactive type room temperature colored asphalt of the present invention (sometimes referred to simply as "the method of the present invention" in the present invention), which comprises sequentially adding a specified amount of reactive solvent, aqueous Steps for epoxy resin, coupling agent and pigment. Specifically, it includes (1) heating the petroleum resin to 150-200°C, adding a reactive solvent, stirring at the first stirring speed for 5-10 minutes, and then continuing to stir at the second stirring speed for 1-5 minutes to obtain a mixed solution (2) add water-based epoxy resin to the mixed solution, stir at the first stirring speed for 3-5min, then continue to stir at the second stirring speed for 5-10min to obtain the suspension; (3) to the step (2) Add coupling agent to the suspension, stir at the first stirring speed for 1-5min, then continue stirring at the second stirring speed...

Embodiment 1

[0042] The preparation of the reaction type normal temperature colored asphalt of the present embodiment is as follows:

[0043] (1) take raw material respectively by following weight parts, the petroleum resin of 50 weight parts, 25 weight parts reaction type solvents, 15 weight parts coupling agents, 15 weight parts waterborne epoxy resins and 3 weight parts iron oxide red (99.6 % less than 0.15mm). The reactive solvent is obtained by mixing 20 parts by weight of oleic acid, 6 parts by weight of dodecyl dimethyl betaine and 4 parts by weight of tris-(dimethylaminomethyl)phenol polymer.

[0044] (2) Heat the petroleum resin to 170°C, and stir at a slow speed (30 rpm) for 1 hour, then keep warm at a slow speed and wait for the next process;

[0045] (3) Add the reactive solvent weighed by the above parts into the petroleum resin, stir at a slow speed for 6 minutes, then stir at a medium speed (70 rpm) for about 4 minutes until the reactive solvent is evenly dispersed; and sti...

Embodiment 2

[0051] The preparation of the reaction type normal temperature colored asphalt of the present embodiment is as follows:

[0052] (1) take raw material respectively by following weight parts, the petroleum resin of 55 parts by weight, 26 parts by weight of reactive solvent, 18 parts by weight of coupling agent, 20 parts by weight of water-based epoxy resin and 4 parts by weight of iron oxide yellow (98.6 % less than 0.15mm). The reactive solvent is obtained by mixing 23 parts by weight of oleic acid, 8 parts by weight of dodecyl dimethyl betaine and 3 parts by weight of tris-(dimethylaminomethyl)phenol polymer.

[0053] (2) Heat the petroleum resin to 170°C, and stir at a slow speed (35 rpm) for 1 hour, then keep it warm at a slow speed and wait for the next process;

[0054] (3) Add the reactive solvent weighed by the above parts into the petroleum resin, stir at a slow speed for 6 minutes, then stir at a medium speed (80 rpm) for about 4 minutes until the reactive solvent is...

Abstract

The invention discloses reactive-type normal temperature color asphalt and a preparation method and an application thereof. The color asphalt comprises, by weight, 50-60 parts of petroleum resin, 20-30 parts of a reactive solvent, 10-20 parts of a coupling agent, 10-20 parts of water-borne epoxy resin, and 2-5 parts of a pigment. The color asphalt is free of a heating step and an aggregate heatingstep before construction and application of a color asphalt mixture, so that the color asphalt is easier to construct and is more energy-saving and environment-friendly. Besides, the color asphalt can be mixed as required, so that the color asphalt is more extensive in application range.

Description

technical field [0001] The invention relates to the field of asphalt pavement materials, in particular to a reactive normal temperature colored asphalt and its preparation method and application. Background technique [0002] With the continuous improvement of people's aesthetic requirements in recent years, the requirements for the aesthetics or functional distinction of roads have become increasingly prominent. As a common pavement material, colored asphalt is mainly used in parks, scenic roads, greenways, and bicycle lanes due to its diverse and bright colors. It has the advantages of beauty, eye-catching, and visual guidance. [0003] At present, the preparation method of colored asphalt comprises: 1) ordinary asphalt is dyed after being decolorized; 2) petroleum resin is used as the main cementing material, and pigments can be directly used for coloring because the petroleum resin is light in color. The above-mentioned first method has been abandoned because it needs t...
