Description
Technical field
The present invention relates to bituminous composition, be specifically related to a kind of radiactive and branching block copolymer and preparation method thereof.
Background technology
Petroleum pitch has been widely used in the fields such as highway, airport, building, but owing to himself there is a series of deficiency, as deliquescing during high temperature, low temperature becomes fragile, and ageing-resistant, fatigue is bad, greatly reduces the work-ing life on road surface.Along with the continuous increase of traffic loading, the maintenance cycle of prevailing roadway also constantly shortens, and maintenance cost increases sharply.Meanwhile, increasing of servicing time also have impact on traffic.The investigation and application of high performance modified bitumen has become an urgent demand of current road construction.
US4530652 describes the pitch roof of high-vinyl conjugated-diolefin/uni-vinyl aromatic block copolymers as modified rubber or the use of water-proof material properties-correcting agent.By introducing this type of properties-correcting agent, adding activity and the reactivity of polymkeric substance, improve the consistency of polymkeric substance and pitch.Modified polymkeric substance and pitch is blended can obtain excellent property and the good modifying asphalt of package stability.Due to the singularity of its polymkeric substance, use is subject to certain restrictions.
US4567222 adopts block SBS to be added in pitch, with polysulfide as coupling agent, produces force of cohesion and flexibility that irreversible chemical key improves pitch, modifying asphalt at high temperature Rut resistance and deal with the ability of cracking at low temperatures.But it must make mother liquor, mix with pitch again after compound and polysulfide being dissolved with crude oil Atmospheric vacuum distillate, the modifying asphalt that package stability is good can be obtained, but also need the lights removal in mother liquor in the operating process later stage, process versus busy and the light constituent removed easily causes environmental pollution.Simultaneously SBS is expensive, and its addition is subject to strict restriction, and the good high molecular SBS elastomerics of modification not easily disperses in pitch, and bad package stability and quite high viscosity all can cause polymer material to be difficult to process.
In sum, the problem solved emphatically is needed when the package stability can finding out modifying asphalt is asphalt modification, although above patent both provides some solutions, but also there is certain technical limitation, as complicated process of preparation, high to equipment requirements, or to environment, make it be subject to certain restrictions.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of radiactive and branching block copolymer and preparation method thereof.The present invention is undertaken composite by selecting the polymkeric substance of different composition or structure, utilizes the complementary action between their performances to carry out the good radiactive and branching block copolymer of processability.This radiactive and branching block copolymer preparation cost is lower, stability and good fluidity.
A kind of radiactive and branching block copolymer technical scheme of the present invention is that said composition comprises:
80-98 weight part pitch;
1-10 parts by weight of plasticizer;
1-10 weight part waste Crumb rubber;
0.1-2 weight part stablizer.
Pitch is one or more the mixture in petroleum pitch, coal-tar pitch, oil sands bitumen, rock asphalt.
The stable hydrocarbon of pitch is 5-25wt%, and aromatic hydrocarbon is 30-60wt%, and colloid is 20-40wt%, and bituminous matter is 0.05-15wt%.
Softening agent is one or more the mixture in the multipolymer of polyethylene wax, alpha-olefin and unsaturated epoxy compound and esters of unsaturated carboxylic acids, alpha-olefin and unsaturated carboxylic acid ester copolymer, Racemic glycidol ester compound, petroleum resin, coumarone indene resin.
Waste Crumb rubber is 40 order-80 orders.
Stablizer is one or more the mixture among organo-peroxide, metal oxide, sulphur, vulcanization accelerator.
The preparation method of described radiactive and branching block copolymer, it is characterized in that, step is: by the asphalt heating of 80-98 weight part to 100-250 DEG C, add the softening agent of 1-10 weight part successively, 1-10 weight part waste Crumb rubber and 0.1-2 weight part stablizer, 0.5-4 hour is reacted, rotating speed 500-5,000 rev/min under high shear forces.
Preferred steps is: by the asphalt heating of 80-98 weight part to 150-200 DEG C, adds the softening agent of 1-10 weight part successively, 1-10 weight part waste Crumb rubber and 0.1-2 weight part stablizer, 1-3 hour is reacted under high shear forces, rotating speed 1,000-3,000 rev/min.
Concrete steps are: 85 weight part petroleum pitch are heated to 160 DEG C, add 7 weight account polyethylene wax softening agent subsequently, 7 weight part waste Crumb rubbers, 1 part by weight of elemental S stablizer, with high-shear mixer 150 DEG C of mixing 80 minutes.
Beneficial effect of the present invention is: bituminous composition of the present invention comprises: 80-98 weight part pitch; 1-10 parts by weight of plasticizer; 1-10 weight part waste Crumb rubber; 0.1-2 weight part stablizer.Add waste Crumb rubber carry out modification can improve pitch itself exist some row problems, as deliquescing during high temperature, the factors such as low temperature becomes fragile, ageing-resistant, add softening agent can improve waste Crumb rubber and not easily process, in construction process or the situation that in storage process, waste Crumb rubber is easily separated with Asphalt Production looks.Stablizer can make waste Crumb rubber and softening agent in pitch, form crosslinked space net structure, part pitch can also be made to be grafted in the structure of waste Crumb rubber and softening agent simultaneously, thus increase the stability of modified pitch.
The present invention is undertaken composite by selecting the polymkeric substance of different composition or structure, utilizes the complementary action between their performances to carry out the good radiactive and branching block copolymer of processability, and composition or the different polymkeric substance of structure have different impacts to the performance after asphalt modification.Generally speaking, the polymkeric substance containing polar functional group in the lower or molecular structure of molecular weight and the consistency of pitch better, and the blended rear excellent storage stability of pitch.Radiactive and branching block copolymer preparation cost of the present invention is lower, stability and good fluidity.
