Description
Technical field
The present invention relates to a kind of chromatic bituminous cement and preparation method thereof.
Background technology
Adopt color asphalt concrete road surface pavement in the road, one has beautifying city, road improvement environment, shows Urban style effect, is applied particularly to the ground such as avenue, square, landscaped area, park and tourist sight road; Its two Colorful Asphalt Pavement has induction wagon flow, makes the effect of traffic administration visualize, is applied particularly to the section and track of distinguishing difference in functionality, to improve the recognition effect of officer, increases the traffic capacity and the traffic safety of road; Its three novel Colorful Asphalt Pavement, higher than plain asphalt surface friction coefficient, so also have anti-skidding effect.When driver runs into emergency situation brake, colored road surface can prevent defective steering stabilizer.At different temperature and outside atmosphere effect, its high-temperature stability, anti-water damage and weather resistance are all very good, and there is not distortion, asphalt membrane such as to peel off at the phenomenon, good with basic unit cohesiveness.
Colorful Asphalt Pavement mainly refers to the bituminous concrete pavement adding pigment, use petroleum resin (albino bitumen) and in compound, add the bituminous pavement of pigment, what color asphalt used is light color (or colourless) agglutinate, use more kind at present, it adopts modern petrochemical product, as perfume oil, polymkeric substance, resin etc. mix the binder suitable with plain asphalt performance, then add certain pigment, make it to present certain color.
Chinese patent ZL03802619.X discloses a kind of colourable binder compositions for the synthesis of pitch, and described composition contains resin, lubricating oil and/or lubricating oil extract and amides additive; Chinese patent ZL93107531 discloses a kind of Binder for Colored Pavement, and its composition mainly comprises petroleum resin, SBS and lube oil finishing and extracts oil out.The principal feature of these patents is the synthetic asphalts adopting resin, lubricating oil and/or lube oil finishing to extract oil and a small amount of mixed with polymers formation colourable binder compositions out above.
Petroleum resin and extract oil of lubricating oil synthesis albino bitumen there is no the macromolecular substance such as traditional asphalt studies on asphaltene, therefore the performance of color asphalt comparatively general black pitch still have gap, especially high-temperature behavior.Partly can improve the performance of chromatic bitumen mixture by adding a large amount of high molecular polymer such as SBS, PE, EVA, SBR wherein, but effect is still undesirable.If polymkeric substance at the addition of color asphalt more than 10%, although chromatic bitumen mixture high-temperature behavior can be made to meet the demands, but the problem that viscosity is excessive can be produced, cause color asphalt producing, storage, transport, the paving of pumping and compound, the link such as roll and go wrong; On the other hand, the cost of the color asphalt of high polymers content is very high.Because the high-temperature behavior of color asphalt is not enough, cause it can not be applied in the occasions such as the comparatively large or porous pavement of southern high-temperature, the volume of traffic.

A kind of preparation method of chromatic bituminous cement, the rubber oil of above-mentioned weight percent is heated to 170 DEG C, then C5 petroleum resin, C9 petroleum resin, ethylene-vinyl acetate copolymer, polyamide resin and urethane is added according to above-mentioned weight percent, stir 2-4h, i.e. obtained chromatic bituminous cement.
Beneficial effect of the present invention is: this agglutinate high-temperature behavior is strong, Heat stability is good, adhesivity are strong, snappiness good, anti-water damage property is strong, and preparation method is simple, especially can the occasion use such as comparatively large or porous pavement at southern high-temperature, the volume of traffic.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail below:
A kind of chromatic bituminous cement, comprises the material composition of following weight percent: the urethane of the rubber oil of the C5 petroleum resin of 10%-40%, the C9 petroleum resin of 10%-40%, 30%-70%, the ethylene-vinyl acetate copolymer of 2%-8%, the polyamide resin of 2%-8% and 2%-8%.
Wherein, C5 petroleum resin are cuts of cracking ethylene, form through thermopolymerization or catalyzed polymerization, and average molecular weight is between 1000-3000.C5 petroleum resin are good with high, the fast viscosity of its stripping bonding strength, adhesiveproperties stable, melt viscosity is appropriate, are thus widely used.C5 petroleum resin most important function in color asphalt is to provide adhesivity, but because common C5 petroleum resin relative molecular mass is less, softening temperature is low and contain more unsaturated hydrocarbons, cause its equal Shortcomings in thermostability, intensity and acid resistance, solvent resistance etc., the softening temperature of the color asphalt that therefore common C5 resin-made is standby and thermostability poor.The present invention preferred high softening-point C5 petroleum resin are as raw material, the softening temperature of common C5 petroleum resin is at 90-110 DEG C, high softening-point C5 petroleum resin of the present invention refer to the C5 petroleum pitch of softening temperature more than 110 DEG C, the softening temperature that the C5 petroleum resin of high softening-point are modulated out is high, Heat stability is good, adhesivity is strong; It is raw material production that C9 petroleum resin refer to pyrolysis gasoline hydrogenation by product C9 cut, and molecular weight is generally 500-1000.Comparatively C5 petroleum resin are high for the softening temperature of C9 petroleum resin, are the key components of the high stability energy in color asphalt.The softening temperature of C9 petroleum resin is 100 DEG C-160 DEG C, and the preferred softening temperature of the present invention is at the C9 petroleum resin of 140 DEG C-160 DEG C.The petroleum resin of high softening-point can improve the high-temperature behavior of chromatic bituminous cement; Rubber oil is rubber processing oil, and rubber oil mainly improves the elasticity of rubber, snappiness, elasticity and workability.The object adding rubber oil in chromatic bituminous cement dissolves other composition of chromatic bituminous cement, improves snappiness and the low-temperature performance of color asphalt.The preferred naphthenic rubber oil of the present invention and aromatic base rubber oil, 100 DEG C of kinematic viscosity of rubber oil are 8-14; Ethylene-vinyl acetate copolymer is commercially available prod, UE653 as poly-in Asia, Taiwan, and wherein VA content is at 28%, MI:400g/10min; Polyamide resin is commercially available prod, as the molten type polyamide resin of rainbow space HY-108 benzene, wherein softening temperature is 112 DEG C, and polyamide resin improves color asphalt high-temperature behavior on the one hand, amide group can strengthen color asphalt and the adhesivity of gathering materials, and significantly improves the anti-water damage property of color asphalt; Urethane is diphenylmethanediisocyanate and the propylene glycol segmented copolymer according to quality 1:1 polycondensation, and preferably the molecular weight of urethane is 40000-100000, the high-temperature behavior that significantly can improve chromatic bituminous cement of urethane.
The preparation method of this chromatic bituminous cement: the rubber oil of above-mentioned weight percent is heated to 170 DEG C, then C5 petroleum resin, C9 petroleum resin, ethylene-vinyl acetate copolymer, polyamide resin and urethane is added according to above-mentioned weight percent, stir 2-4h, i.e. obtained chromatic bituminous cement.
Experimentally and summary of experience, the urethane of the rubber oil of the C5 petroleum resin of the material composition of this agglutinate and the weight percent of correspondence: 15%-25%, the C9 petroleum resin of 15%-25%, 40%-60%, the ethylene-vinyl acetate copolymer of 3%-6%, the polyamide resin of 3%-6% and 3%-6%.
