Problems solved by technology

[0004] The prior art has the following defects: ① After using the existing materials to pave the colored pavement and construct it, the problem of discoloration occurs, especially for light-colored colors
②The weather resistance is poor, and the color will fade about one month after the construction is completed
③Currently, the color pavement bonding materials on the market are uneven, and the quality is generally poor, which not only causes waste of resources and economic losses, but also seriously exceeds the standard of VOC, contains harmful substances, and endangers the health of the masses

preparation example Construction

[0027] A preparation method of environment-friendly colored pavement binder, specifically comprising the following steps:

[0028] (1) take each component raw material by weight percentage, for subsequent use;

[0029] (2) Put the environment-friendly aromatic oil into the reactor, and when heated to 150-170°C, add hydrogenated petroleum resin and terpene resin in turn, stir for 50-70min, maintain the temperature at 150-170°C, and stir at a speed of 600- 800rpm / min;

[0030] (3) Add styrene-butadiene rubber and SBS to the liquid after the reaction in step (2), continue to stir and swell for 20-40min, maintain the temperature at 150-170°C, and stir at a speed of 600-800rpm / min;

[0031] (4) Add oil-based color paste to the liquid after the swelling in step (3) is completed, and continue to stir for 20-30 minutes, the temperature is maintained at 150-170° C., and the stirring speed is 600-800 rpm / min;

[0032] (5) Add an antioxidant to the liquid after the reaction in step (4)...

Embodiment 1-5

[0035] The raw materials of each component were weighed according to the weight percentage in Table 1.

[0036] Table 1: each component weight percent (unit: %) of embodiment 1-5

[0037]

[0038]

[0039] According to the ratios and dosages proposed in the weight percentage scheme of each component raw material in Examples 1-5, the color binder was prepared by the same preparation method as above, and the performance test was carried out, as shown in Table 2.

[0040] The detection result of table 2 embodiment 1-5

[0041]

[0042]

[0043] It can be seen from Table 2 that based on the blending ratio and processing technology of the aforementioned components, the products of each example are better than the standard requirements of JTG F40-2019 for road petroleum ordinary asphalt, and most of them meet the requirements of JTG F40-2019 for polymer Standard requirements for modified asphalt. From the experimental data, it can be seen that the penetration index PI,...

Embodiment 6

[0045] A preparation method of environment-friendly colored pavement binder, specifically comprising the following steps:

[0046] (1) take by weighing each component raw material of weight percentage described in embodiment 3, for subsequent use;

[0047] (2) Put the environmentally friendly aromatic oil into the reactor, and when heated to 150°C, add hydrogenated petroleum resin and terpene resin in turn, stir for 50 minutes, keep the temperature at 150°C, and the stirring speed is 600rpm / min;

[0048] (3) Add styrene-butadiene rubber and SBS to the liquid after the reaction in step (2), continue to stir and swell for 20 minutes, maintain the temperature at 150° C., and stir at a speed of 600 rpm / min;

[0049] (4) Add oil-based color paste to the liquid after the swelling in step (3) is completed, and continue to stir for 20 minutes, the temperature is maintained at 150 ° C, and the stirring speed is 600 rpm / min;

[0050](5) Add an antioxidant to the liquid after the reacti...

Abstract

The invention discloses an environment-friendly colored pavement binder which comprises the following components: 20-45% of hydrogenated petroleum resin, 20-45% of terpene resin, 5-10% of environment-friendly aromatic hydrocarbon oil, 1-9% of butadiene styrene rubber, 1-9% of SBS, 2-9% of oily color paste and 1-3% of an antioxidant. The preparation method comprises the following steps: heating theenvironment-friendly aromatic hydrocarbon oil to 150-170 DEG C, sequentially adding the hydrogenated petroleum resin and terpene resin, and conducting stirring for 50-70 minutes; then controlling thetemperature to be 150-170 DEG C, adding styrene butadiene rubber and SBS, and then conducting stirring and swelling for 20-40 minutes; continuously conducting heating and stirring, adding the oily color paste, and conducting stirring for 20-30 minutes; and finally, adding an antioxidant, conducting grinding twice by a colloid mill, conducting sampling and detecting, and loading an obtained product into a finished product vehicle after the detection is qualified. The preparation method disclosed by the invention is simple, and the product has the advantages of low volatility, no toxicity, richcolors, strong weather resistance, lasting colors and the like.

Description

technical field [0001] The invention relates to the field of colored pavement construction, in particular to an environment-friendly colored pavement binder and a preparation method thereof. Background technique [0002] With the rapid development of our country's economic construction, in order to beautify the environment and show the style of the city, all provinces and cities try to make the urban environment "green" and the urban roads "light up" in the construction of urban infrastructure, so colored roads came into being , is an important symbol in the pace of urban modernization, and it has a wide range of practicability for social welfare undertakings such as beautifying public communities, embellishing urban buildings and garden buildings, and warning road traffic safety. [0003] The mechanical properties and rheological properties of colored pavement binders need to be the same as those of general road heavy traffic asphalt. The main principle of colored pavement ...
