Embodiment 1

[0035] (1) Mix 35 parts of paraffin oil, 5 parts of inorganic pigments, nano-montmorillonite 8, and wollastonite 12 in a high-speed mixer for 20 minutes at a speed of 400 rpm to obtain material 1;

[0036] (2) Mix 15 parts of sarin resin, 5 parts of POE, 10 parts of light-colored rosin, and 10 parts of cross-linked polyethylene in a high-speed mixer. The speed of the high-speed mixer is 400 rpm, and the time is 5 minutes to obtain material 2;

[0037] (3) Add the material 2 in step 2 from the main feeding port and the material 1 in step 1 from the side feeding port into the parallel twin-screw extruder to granulate. Granules, and the resulting pellets were dried at 60°C for 2 hours to obtain the colored asphalt raw material.

Embodiment 2

[0039] (1) 45 parts of paraffin oil, 5 parts of inorganic pigments, 15 parts of nano-montmorillonite, and 5 parts of wollastonite were mixed in a high-speed mixer for 20 minutes at a speed of 400 rpm to obtain material 1;

[0040] (2) Mix 10 parts of sarin resin, 5 parts of POE, 8 parts of light-colored rosin, and 7 parts of cross-linked polyethylene in a high-speed mixer. The speed of the high-speed mixer is 400 rpm, and the time is 5 minutes to obtain material 2;

[0041] (3) Add the material 2 in step 2 from the main feeding port and the material 1 in step 1 from the side feeding port into the parallel twin-screw extruder to granulate. Granules, and the resulting pellets were dried at 60°C for 2 hours to obtain the colored asphalt raw material.

Embodiment 3

[0047] The preparation method of colored asphalt mixture is as follows:

[0048] The color asphalt raw material prepared in the above-mentioned 2 embodiments and comparative example 1 of 25% mass fraction and a small amount of crosslinking agent, dispersant and other auxiliary agents are added to the asphalt aggregate (coarse aggregate , fine aggregate, ore powder), shear and grind for 30 minutes through the mill of the mixer truck, and stir and develop into a colored asphalt mixture.

Abstract

The invention discloses color asphalt and a preparation method thereof. The color asphalt is prepared from the following ingredients in parts by weight: 30 to 45 parts of high-viscosity colorless paraffin oil, 8 to 18 parts of sarin resin, 3 to 6 parts of POE, 5 to 10 parts of pale rosin, 5 to 10 parts of crosslinked polyethylene, 2 to 15 parts of inorganic pigment, 6 to 15 parts of thickening agent and 5 to 15 parts of fillers. The colors of the color asphalt is various; different requirements of different application environment on the color can be met; the characteristics of peeling resistance, high-temperature resistance, weather resistance, no color change, high adhesion and waterproof performance can be realized; all characteristics of meeting the requirement of the hot mixed asphaltare realized; the application range is wide; the general road indication function is achieved; the visual attractiveness, warning effects and the like are also realized.

Description

technical field [0001] The invention relates to the application field of asphalt modification, in particular to a colored asphalt and a preparation method thereof. Background technique [0002] Asphalt is a product of crude oil processing. It is a black or dark brown viscous liquid, semi-solid or solid at room temperature. It mainly contains hydrocarbons and non-hydrocarbon derivatives. It is a black paving material that is very familiar to the public. [0003] With the development of science and technology, various kinds of colored asphalt gradually appeared, one of which is directly modified by asphalt, this kind of cement has the characteristics of strong anti-aging ability of asphalt, and the color is brownish red; It is made by directly decolorizing black asphalt to produce colorless binder and adding coloring material; there is also a binder that imitates petroleum asphalt components and is modified by blending petroleum resin, polymer modifiers, pigments, etc. , is t...
