Abstract
The invention discloses modified asphalt. The modified asphalt is characterized in that the modified asphalt is prepared by using petroleum resin, rubber operating oil, naphthenic oil, thermoplastic styrene-butadiene rubber (SBS) and polypropylene wax as raw materials, the modified asphalt comprises the following raw materials in parts by weight: 40-50 parts of petroleum resin, 10-15 parts of rubber operating oil, 10-15 parts of naphthenic oil, 12-15 parts of SBS and 0.01-0.03 part of polypropylene wax. The modified asphalt disclosed by the invention has excellent performances, can be used as heavy-duty traffic asphalt, is light yellow, has relatively good coloring property and excellent adhesive property to a coloring agent, can be manufactured into colored asphalt to beautify the environment, has strong color contrasts, and can be used for dividing different lane uses and reducing the traffic accidents. In addition, compared with conventional black asphalt which can cause pollution because of volatilization of a large amount of light-weight components, the modified asphalt disclosed by the invention is stable in performance, less in volatile component, safe and environmental friendly.
Description
Technical field
The present invention relates to a kind of traffic pitch, be specifically related to a kind of light modifying asphalt.
Background technology
Pitch is that the mankind apply the earliest and one of a large amount of engineering materialss that use still so far.But traditional matrix pitch is black, therefore, for a long time, road surface form only has two kinds of the cement concrete pavement of grey and the bituminous concrete pavements of black.Along with social development, the road surface form of solid color cannot meet people for the requirement of the division of function path and sight.Change road color, become the focus that road industry is tried to be the first and paid close attention to.For pitch, change colour, existing two kinds of methods: the one, with suitable solvent, the dark asphalt matter in petroleum pitch is sloughed, leave other components of paler colour; The color asphalt custom that this kind of mode produced is called decolouring pitch, although obtained having the albino bitumen of color-adjustable, this production technique is extremely complicated, energy dissipation is huge, therefore cost is also very high, finally causes holding at high price, and has no market.The 2nd, utilize modern petrochemicals to mix light color cementing material, but its pavement performance can not meet compare Gao road with requiring.
Polymer modified asphalt definition, be the additive (properties-correcting agent) such as admixture rubber, resin, high molecular polymer or other fillers in pitch, or take measures such as pitch mild oxidation processing, the performance that makes pitch is improved and the asphaltic binder made.
Summary of the invention
The object of the invention is to provide a kind of modifying asphalt, this modifying asphalt be light, tasteless, pavement performance is remarkable, be easy to colorant combination, be the high-quality color pitch with good market.
Another object of the present invention is to provide the preparation method of above-mentioned modifying asphalt, the method simple process, with low cost.
The object of the invention realizes by following technical measures, below all in weight part and or mass ratio:
A modifying asphalt, is characterized in that: take petroleum resin, rubber processing oil, naphthenic oil, thermoplastic styrene butadiene rubber (SBS) and Poly Propylene Wax makes as raw material; Described petroleum resin account for 40～50 parts, and rubber processing oil accounts for 10～15 parts, and naphthenic oil accounts for 10～15 parts, and SBS accounts for 12～15 parts, and Poly Propylene Wax accounts for 0.01～0.03 part.
Above-mentioned petroleum resin are preferably one or more in carbon nine resins, carbon five resins or coumarone indene resin.Further preferred mass is than being the coumarone indene resin of 3:2 and carbon five resins.
Preferably, in order to improve the performance of modifying asphalt of the present invention, above-mentioned petroleum resin account for 44～47 parts, and rubber processing oil accounts for 13～15 parts, and naphthenic oil accounts for 10～12 parts, and SBS accounts for 13～14 parts, and Poly Propylene Wax accounts for 0.014～0.019 part of whole system.
More preferably, above-mentioned petroleum resin account for 46 parts, and rubber processing oil accounts for 14 parts, and naphthenic oil accounts for 10 parts, and SBS accounts for 14 parts, and Poly Propylene Wax accounts for 0.02 part of whole system.
Above raw material petroleum resin, rubber processing oil, naphthenic oil, thermoplastic styrene butadiene rubber (SBS) and Poly Propylene Wax are the marketable material that those skilled in the art know.
The preparation method of above-mentioned modifying asphalt, is characterized in that, carries out as follows:
A. raw material is prepared
Take the petroleum resin of above-mentioned weight part, rubber processing oil, naphthenic oil, thermoplastic styrene butadiene rubber (SBS), Poly Propylene Wax;
B. production feeds intake
The petroleum resin of aforementioned proportion, rubber processing oil, naphthenic oil are followed to stir and add in 155 ℃～160 ℃ oil bath devices, melt to petroleum resin, by amount, add again SBS, the Poly Propylene Wax of aforementioned proportion, added and continued to stir 15min～30min after raw material each raw material is merged evenly, during keep oil bath device temperature at 155 ℃～160 ℃; Then enter shear, shearing rate is controlled at 5000r/min～9000r/min, shear time 15min～30min; Shear the complete modifying asphalt of the present invention that makes afterwards.
Modifying asphalt of the present invention has following beneficial effect:
Pavement Performance of Modified Asphalt of the present invention is excellent, can be used as Heavy Traffic pitch; This modifying asphalt is light yellow simultaneously, has better tint permanence, excellent with the adhesion property of tinting material, is made into color asphalt and beautifies the environment, and strong color contrast, divides different tracks purposes, reduces traffic accident.In addition, conventional black pitch brings pollution because of a large amount of volatilizations of light component, and the present invention changes the stable performance of surname bituminous material, and volatile matter is few, safe green environmental protection.
Embodiment
Below by embodiment, the present invention is specifically described; be necessary to be pointed out that at this following examples are only used to further illustrate the present invention; can not be interpreted as limiting the scope of the invention; without departing from the spirit and substance of the case in the present invention; the modification that the inventive method, step or condition are done or replacement, all belong to scope of the present invention.Below all in weight part and or mass percent.
