Abstract
The invention relates to hard asphalt, comprising according to percent by weight: Boscan crude oil and Merey-16 crude oil having a weight ratio of 30-90%:10-70%, Boscan crude oil and Merey-16 crude oil having a weight ratio of 70%:30%, and additives: 20-40% of extract oil, 15-30% of rubber oil, 10-20% of second side stream of vacuum distillation, 10-20% of third side stream of vacuum distillation, and 10-20% of fourth side stream of vacuum distillation. A vacuum direct drawing process is used in the production method under a pressure of 1.33 kpa to 6.67 kpa at a vacuum vapor temperature of 290-360 DEG C, and temperature for conversion to normal pressure is 440-470 DEG C. The hard asphalt and the production method thereof have the advantages that softening point is high, high temperature performance is good, low temperature performance is improved, penetrating depth after addition remains in a qualified range, and the problem that the asphalt flows at high temperature in summer and cracks at low temperature in winter is solved.
Description
Technical field
The invention belongs to field of bitumen technology, specifically, relate to a kind of hard grades of bitumen and production method thereof。
Background technology
In recent years, China's transportation cause obtains fast development, and the volume of traffic constantly increases, and seriously, asphalt pavement rut becomes one of the most prominent early disease for heavy duty, overload so that increasing people participates in the research of hard grades of bitumen road surface。
Hard grades of bitumen needle penetration is low, and softening point is high, has good high-temperature stability, and the high temperature rutting resistance improving road is had good effect。
Hard grades of bitumen is a kind of low-grade Colophonium, and such Asphalt Penetration is low, softening point is high (>=60 DEG C), has good high-temperature stability, for road paving, the high temperature rutting resistance improving road is had good effect。It is domestic at present that what occupy main hard grades of bitumen market is 30, No. 50 asphaltic productses。
Colophonium, as the pavement material of road, building and water conservancy industry, develops very fast, but plain asphalt is relatively big to the sensitivity of temperature, the problem that there is summer high temperature trickling, winter low temperature cracking。
Summary of the invention
Instant invention overcomes shortcoming of the prior art, it is provided that a kind of hard grades of bitumen and production method thereof, softening point is high, and high-temperature behavior is good, and its cryogenic property is also improved。
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of hard grades of bitumen, including raw material: weight ratio is Persian bank crude oil and Ma Rui-16 crude oil of 30～90%:10～70%。
Further, weight ratio is Persian bank crude oil and Ma Rui-16 crude oil of 70:30%。
Further, add additive: tapped oil 20-40%, rubber oil 15-30%, decompression distillation second line of distillation 10-20%, the decompression distillation line 10-20% that subtracts three, the decompression distillation line 10-20% that subtracts four。
The production method of a kind of hard grades of bitumen, adopts decompression directly to pull out technique, directly pulls out decompressed pressure: 1.33kpa-6.67kpa, and reduce pressure vapor phase temperature: 290-360 DEG C, converts normal pressure temperature to: 440-470 DEG C。
Further, described decompressed pressure: 1.33kpa, reduce pressure vapor phase temperature, 305 DEG C, is equivalent to normal pressure temperature: 470 DEG C。
Further, described decompressed pressure: 1.33kpa, reduce pressure vapor phase temperature, 296 DEG C, is equivalent to normal pressure temperature 460 DEG C。
Further, described decompressed pressure: 6.67kpa, reduce pressure vapor phase temperature, 336 DEG C, is equivalent to normal pressure temperature 450 DEG C。
Compared with prior art, the invention has the beneficial effects as follows:
A kind of hard grades of bitumen of the present invention and production method softening point thereof are high, and high-temperature behavior is good, and its cryogenic property is improved, and makes the needle penetration after interpolation still within qualified scope simultaneously, the problem solving the trickling of Colophonium summer high temperature, winter low temperature cracking。
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention。
A kind of hard grades of bitumen of the present invention, including raw material: weight ratio is Persian bank crude oil and Ma Rui-16 crude oil of 70:30%, is simultaneously introduced additive: tapped oil 30%, rubber oil 25%, decompression distillation second line of distillation 20%, the decompression distillation line 15% that subtracts three, decompression distillation subtract four line 10%。
A kind of production method of hard grades of bitumen, adopt decompression directly pulls out technique, base material 1 directly pull out decompressed pressure: 1.33kpa, reduce pressure vapor phase temperature, 305 DEG C, be equivalent to normal pressure temperature: 470 DEG C。
Base material 2 directly pull out decompressed pressure: 1.33kpa, reduce pressure vapor phase temperature, 296 DEG C, be equivalent to normal pressure temperature 460 DEG C。
Base material 3 directly pull out decompressed pressure: 6.67kpa, reduce pressure vapor phase temperature, 336 DEG C, be equivalent to normal pressure temperature 450 DEG C。
