Abstract
The invention discloses a colorful asphalt binder. The component of the colorful asphalt binder of the invention calculated by weight percentage comprises that: 20-65 per cent of petroleum resin, 30-79 per cent of lubricant refined extract oil and 1-5 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, which allows an easy construction. As the same time, the reduction of construction temperature and odor emitted by the binder are which are in favor of environment protection. As the same time, add of SEBS and 3 -9 per cent of SIS allows the colorful asphalt binder to be provided with better high-temperature stability.
Description
Technical field
The present invention relates to a kind of bituminous cements, particularly a kind of agglutinate that is used for color asphalt.
Background technology
The mechanical property of chromatic bituminous cement and rheological property and general road are identical with heavy traffic paving asphalt, the cardinal principle on chromatic bituminous cement road surface adopts chromatic bituminous cement exactly, make it have various needed colors by various adding pigment, simultaneously by adopting color aggregate or light building stones, make it that more permanent color effect be arranged, good chromatic bituminous cement should satisfy the requirement of following three aspects:
The performance of chromatic bituminous cement is good, should reach the requirement of heavy traffic paving asphalt even modifying asphalt as far as possible; Anti-rut performance is good; Anti-water damage property is good.
At present, there have been many patents and document to disclose chromatic bituminous cement separately, the suitability for industrialized production that has, as the technology that patent GB1226234, EP-A0179510 and EP-A0330281 are disclosed, and the technology reported of Chinese patent application 03802619.X and ZL93107531.A significant defective of above-mentioned patent disclosure is, when concrete construction, need be heated high temperature, not only need a large amount of energy consumptions, and contaminate environment, constructional difficulties also can not add too much ratio of polymer in composition, limited the high-temperature stability of chromatic bituminous cement, be unfavorable for promoting the use of, therefore, a kind of new chromatic bituminous cement of development research has very expectation.
Summary of the invention
This therefore, and the technical problem that the present invention solves is exactly to disclose a kind of chromatic bituminous cement that is easy to construct, to overcome the above-mentioned defective that prior art exists.
The concrete technical scheme that the present invention taked is:
A kind of chromatic bituminous cement, its component comprises by weight percentage:
Oil 30～79%, polyethylene wax 1～5% are extracted in petroleum resin 20～65%, lube oil finishing out.
The petroleum resin of the above-mentioned preferred C9 of petroleum resin can adopt commercially produced product, produce as Korea S Kolon company, and trade(brand)name: the product of Hikotack P140, softening temperature are 100～160 ℃, and preferred 130～150 ℃, molecular-weight average (GPC method) 800～3200;
Lube oil finishing is extracted oil out and is extracted oil out for the lube oil finishing with 360-560 ℃, and 40 ℃ of viscosity are 2～7Pa.S, and fragrance divides content: 50～80wt%.
Its molecular-weight average of above-mentioned polyethylene wax is 3000-6000, and softening temperature is at 120-150 ℃.Add polyethylene wax, construction temperature can obtain lower, and construction is become easily, because construction temperature reduces, the also corresponding minimizing of the smell that agglutinate distributes helps environmental protection, but can not improve high-temperature stability simultaneously.
Therefore, the solution of the present invention also can be mixed styrene-ethylene/butylene-styrene SEBS 3-9% or/and styrene isoprene styrene block copolymer (SIS) SIS 3-9%.SEBS molecular weight 3-35 ten thousand, preferred 10-25 ten thousand; SIS molecular weight 3-30 ten thousand, preferred 10-20 ten thousand.More than two kinds all can adopt the commercially available prod.Add SEBS and SIS and all can improve adhesivity and high-temperature stability.
The preparation method of chromatic bituminous cement of the present invention comprises the steps:
Extract lube oil finishing out oil and be heated to 170～180 ℃, proportionally add petroleum resin, polyethylene wax and SEBS and SIS then, mixed 0.5～3 hour, promptly prepare chromatic bituminous cement.
Chromatic bituminous cement of the present invention can mix the formation asphalt with pigment, pitch, aggregate, is used for making color asphalt road surface, and the addition of chromatic bituminous cement is generally 4～7% of compound weight.
The contriver is through overtesting, be surprised to find, by in conventional chromatic bituminous cement, introducing small amounts of polyethylene waxes, can reduce the mixing of asphalt greatly, pave and roll temperature, and can final color asphalt road surface not had a negative impact, owing to added polyethylene wax, the construction temperature of chromatic bitumen mixture can obtain lower, make construction become easy, simultaneously because the construction temperature reduction, the also corresponding minimizing of the smell that agglutinate distributes helps environmental protection, and the adding of polyethylene wax simultaneously also can make chromatic bituminous cement have better high-temperature stability.
