Problems solved by technology

A notable defect disclosed in the above-mentioned patent is that it needs to be heated to an extremely high temperature during specific construction, which not only requires a large amount of energy consumption, but also pollutes the environment, makes construction difficult, and it is impossible to add too much proportion to the composition. Polymers that limit the high temperature stability of colored asphalt binders are not conducive to popularization and use. Therefore, it is very desirable to develop and research a new colored asphalt binder

Embodiment 1～6

[0018] Raw materials used:

[0019] Refined lubricating oil, viscosity at 40°C: 3.5Pa.S, flash point: 335°C, aromatic content: 68wt%, density at 15°C: 0.98g / cm3

[0020] Petroleum resin, produced by Korea Kolon Company, trade name: Hikotack P140, softening point 145°C, average molecular weight (GPC method) 2200

[0021] Polyethylene wax, molecular weight 3000-6000, softening point 120-150℃

[0022] SBR, the grade produced by Qilu Petrochemical is 1502

[0023] Heat the extracted lubricating oil to 175°C, then add petroleum resin, polyethylene wax and SBR, and stir with a stirrer at a speed of 200 rpm for 60 minutes to prepare the finished colored asphalt binder. The specific composition ratio (percentage by weight), and the performance results of the binder and the mixture tested by the testing method specified in the JTJ052-2000 standard "Testing Procedures for Asphalt and Asphalt Mixtures in Highway Engineering" of the Ministry of Communications of China are shown in Table...

Abstract

The invention discloses a colorful asphalt binder. The component of the colorful asphalt binder of the invention calculated by weight percentage comprises that: 20 per cent-65 per cent of petroleum resin, 30 per cent -79 per cent of lubricant refined extract oil and 1 per cent -5 per cent of polyethylene wax. By pulling a little of polyethylene wax into conventional colorful asphalt binder, temperature of mixing, spreading and rolling of asphalt mixture can be greatly reduced and negative influence on final colorful asphalt pavement is not caused. As the polyethylene wax is added, a reasonably low construction temperature can be obtained, which allows an easy construction. At the same time, the lowering of construction temperature decreases correspondingly the odor emitted by the asphalt binder, which is in favor of environmental protection. Simultaneously, the adding of SBR allows the colorful asphalt binder to be provided with a better high-temperature stability.

Description

technical field [0001] The invention relates to an asphalt binder, in particular to a binder for colored asphalt. Background technique [0002] The mechanical properties and rheological properties of colored asphalt binder are the same as those of general road heavy traffic asphalt. The main principle of colored asphalt binder pavement is to use colored asphalt binder and add various pigments to make it have various required colors. At the same time, by using colored stones or light-colored stones, it can have a longer-lasting color effect. A good colored asphalt binder should meet the following three requirements: [0003] Colored asphalt binder has good performance and should try to meet the requirements of heavy traffic asphalt or even modified asphalt; it has good anti-rutting performance and good water damage resistance. [0004] At present, there have been many patents and documents disclosing their own colored asphalt binders, some of which have been industrialized, ...
