preparation example Construction

[0039] The present invention also provides a kind of preparation method of No. 110 road petroleum asphalt, comprises the following steps:

[0040]100 parts by weight of No. 70 road petroleum asphalt, 1 to 12 parts by weight of minus three line wax oil and 0.2 to 1 weight part of polyphosphoric acid are mixed to obtain No. 110 road petroleum asphalt.

[0041] In the preparation method provided by the present invention, the No. 110 road petroleum asphalt provided by the present invention can be obtained by directly mixing the above-mentioned raw materials in proportion. Wherein, the mixing temperature is preferably 80-180°C, specifically 80°C, 85°C, 90°C, 95°C, 100°C, 105°C, 110°C, 115°C, 120°C, 125°C, 130°C, 135°C, 138°C, 140°C, 145°C, 150°C, 155°C, 160°C, 165°C, 170°C, 175°C or 180°C; the stirring speed of the mixing is preferably 60 to 1000 rpm, which can be specified 60 rpm, 100 rpm, 200 rpm, 300 rpm, 400 rpm, 500 rpm, 600 rpm, 700 rpm, 800 rpm, 900 rpm or 1000 rpm; the mi...

Embodiment 1

[0051] Take a certain quality of Haiyun No. 70 road petroleum asphalt, and conduct a blending experiment with the mass ratio of Haiyun No. 70 road petroleum asphalt: polyphosphoric acid: minus three-line wax oil at a ratio of 100: 0.3: 5.5. The order of reagent addition is first Add polyphosphoric acid to the asphalt, stir for 1 hour, add the minus three line wax oil and continue to stir for 1 hour, the stirring temperature is 138 ℃, and the rotation speed is 400 rpm. In this way, No. 110 road petroleum asphalt is obtained. The test results are shown in the table 2 shows:

[0052] The technical index of No. 110 road petroleum asphalt that table 2 embodiment 1 produces

[0053]

[0054] It can be seen that the indicators of No. 110 road petroleum asphalt prepared in Example 1 all meet the technical index requirements of No. 110 road petroleum asphalt.

Embodiment 2

[0056] Take a certain quality of Haiyun No. 70 road petroleum asphalt, and conduct a blending experiment with the mass ratio of Haiyun No. 70 road petroleum asphalt: polyphosphoric acid: minus three-line wax oil at a ratio of 100: 0.5: 5.5. The order of adding reagents is first Add minus three line wax oil to the asphalt, stir for 1 hour, add minus three line wax oil and continue stirring for 1.0 hour, the stirring temperature is 138°C, and the rotation speed is 400 rpm. In this way, No. 110 road petroleum asphalt is obtained. The test results are as follows Table 3 shows:

[0057] The technical index of No. 110 road petroleum asphalt that table 3 embodiment 2 produces

[0058]

[0059] It can be seen that the indicators of No. 110 road petroleum asphalt prepared in Example 2 all meet the technical index requirements of No. 110 road petroleum asphalt.

Abstract

The invention relates to the field of petrochemical engineering, in particular to #110 road petroleum asphalt and a preparation method thereof. The #110 road petroleum asphalt comprises the followingcomponents in parts by weight: 100 parts of #70 road petroleum asphalt; 1-12 parts of vacuum third-line wax oil; and 0.2 to 1 part of polyphosphoric acid. The #110 road petroleum asphalt meeting the index requirements is obtained by taking the #70 road petroleum asphalt as a main raw material and adding a proper amount of the vacuum third-line wax oil and the polyphosphoric acid as additives, andthe problems of high costs and substandard partial indexes in straight-run production of a small amount of #110 road petroleum asphalt are solved. Experimental results show that the #110 road petroleum asphalt provided by the invention meets the technical index requirements of #110 road petroleum asphalt in Technical Specifications for Construction of Highway Asphalt Pavements JTG F04-2004 of Ministry of Communications, and the key technical indexes are superior to those of straight-run #110 road petroleum asphalt.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to No. 110 road petroleum asphalt and a preparation method thereof. Background technique [0002] According to the different penetration at 25°C, road asphalt can be divided into No. 30 road asphalt, No. 50 road asphalt, No. 70 road asphalt, No. 90 road asphalt, No. 110 road asphalt and so on. According to the high temperature index and low temperature index of the area where road petroleum asphalt is used, it is divided into hot summer and severe cold winter, hot summer and cold winter, hot summer and cold winter, hot summer and warm winter, hot summer and severe cold winter, hot summer and cold winter. According to the performance of asphalt, combined with the characteristics of each temperature zone climate, the use of asphalt and asphalt is divided. For example, No. 70 road petroleum asphalt is suitable for areas with different climates such as hot summer and cold winter, ...
