Technical field
The present invention relates to a kind of road-making material, particularly a kind of composition, preparation method and its usage of high-performance environment-friendly stable form rubber asphalt.
Background technology
According to the definition of traditional rubber asphalt, rubber asphalt is to be processed into rubber powders more than 20 orders with damaged tire, adds pitch to more than 15% part by weight, reacts after 45 minutes more than 180 DEG C, realize the swelling and partial desulfurization of pitch to rubber powder, thereby obtain rubber asphalt mixture.Waste Crumb rubber can obviously improve the high temperature performance of pitch, has long, the advantage such as noise is low of life-span with the road of its laying, has realized the high-efficiency environment friendly utilization of waste resource.
But more than the processing temperature higher (180 DEG C) of rubber asphalt, cold rubber powder adds in heated bitumen lowers the temperature soon, and viscosity is larger, cause the difficulty that heats up, cause not only that power consumption is large, working (machining) efficiency is low, and discharge a large amount of harmful dusty gass in pitch and rubber.In addition when running into the rainy day, hot rubber asphalt do not construct, once park,, there is obviously decay in its performance, viscosity does not meet index request, causes and can not use, once rubber asphalt stops stirring in addition, and the gathering of rubber powder in pitch will occur, and causes equipment damage.
In addition,, when rubber asphalt is produced, because of the volume density lower (0.5 left and right) of rubber powder, rubber powder granule is loose, easily fly upward, the more difficult pitch of sneaking into, causes and is deposited in asphalt surface, assemble heat-dissipating, hold fire hazardous, therefore need special rubber powder and pitch premixing device system.The processing temperature of rubber asphalt is high, and therefore rapid heat dissipation needs the special system that is rapidly heated, and guarantees rubber asphalt normal process.Below the problems such as rubber asphalt device investment is high, and output is restricted have all been caused.
For addressing these problems, patent 03118863.X " asphalt modified with desulfurized rubber powder ", has proposed the asphalt modified with desulfurized rubber powder that a kind of Road construction is used.This modifying asphalt is stirred by high speed shear under comparatively high temps by desulfurization rubber powder, pitch and compatilizer or the grinding of colloidal mill makes, its medium pitch accounts for 70～95% of raw material gross weight, desulfurization rubber powder accounts for 5～30% of raw material gross weight, and compatilizer accounts for 0～1.5% of raw material gross weight.Because properties-correcting agent is desulfurization rubber powder, it has good dissolving swelling property in pitch, simultaneously because desulfurization has produced more active group at vulcanized rubber powder, be conducive to the chemical bonding of rubber powder with pitch, and compatilizer can further increase the interaction of rubber powder and pitch, the modifying asphalt that invention obtains has good high temperature performance and storage stability.Though this invention has proposed desulfurization rubber powder stable system, but the processing temperature of modifying asphalt is high, and the impaired reduction of high-temperature behavior, desulfurization rubber powder is easily reunited and is difficult for adding.
Patent 200710017861.0 " a kind of pitch of rubber asphalt production facility and rubber powder mixing tank ", has proposed rubber powder premixing system, improves rubber powder and sneak into speed and the effect of pitch.Establish supporting seat in the upper end of tank body and be processed with opening for feed, in tank body, the batch mixing bucket connecting with blocking material ring is established in bottom, bottom in tank body is provided with the support of bearing support, on supporting seat, establish electric motor, shaft coupling and propeller shaft couplings for the output shaft of electric motor, between shaft coupling and supporting seat, establish head bearing, and establish scattering plate on the scattering plate axle of propeller shaft couplings, between scattering plate axle and bearing support, set bearing.The pitch of this structure of inventing and rubber powder mixing tank, make liquid bitumen can fully be mixed with rubber powder.Can on rubber asphalt production facility, promote the use of.But this occupation area of equipment is large, invest high.
Manufacture reclaimed rubber for rubber powder desulfurization and also have at present patent; patent 200710132935.5 " a kind of waste and old tyre rubber high shear stress induced desulfurization and method of modifying "; propose to add in high rotating speed, high-shear type co-rotating twin screw extruder; melt extrude that desulphurization reaction sweetening process efficiency is high, productive rate is high, energy expenditure is low; be easy to maximization, mass-producing; desulphurization reaction is easy to control, and reaction process environmental pollution is little.Patent 200910080211.X " a kind of method that adopts twin screw extruder desulfurization regeneration of vulcanized rubber " realizes the desulfurization environment of High Temperature High Pressure under the effect of extruder screw, realizes the desulfurization regeneration of rubber, and this technology is mainly used in reclaimed rubber manufacture.
Patent 200510016292.9 " production unit of appts of modified asphalt by utilizing waste tyre rubber powder " and patent 200610047442.7 " a kind of preparation method who is applicable to industrial rubber powder modified asphalt ", multistage shear at high temperature mill has all been proposed, to improve the blending dispersion effect of rubber powder, but, there is power consumption and pollute the problems such as large in shear at high temperature process, rubber asphalt still exists the problem of easy generation storage segregation and high temperature viscosity decay.
Patent ZL101747637 discloses a kind of low-temperature environment-friendly rubber asphalt, wherein specifically disclose following technology, be after recycle polyethylene mixes by rubber powder and desulfurizing assistant agent and bonded pelleting agent, mix and plastify granulation with screw extrusion press, obtain plasticized granule, particle size is 1-10mm, density 0.6-1.lg/cm3, realize low-temperature environment-friendly modification processing, though but this technique has solved low-temperature environment-friendly problem, but when the storage of gained rubber asphalt, rubber powder easily precipitates, and polyethylene floats, cause segregation, can not be used for quality stability, residual desulfurizing assistant agent can accelerate its further degraded in pitch on the other hand, performance decays.
Summary of the invention
The object of the present invention is to provide a kind of rubber asphalt and preparation thereof and application.Carrying out high temperature by rubber powder and polyolefin elastomer mixes, extrude a kind of desulfurization of preparation, devolatilisation particle, adhesion between this particle, there is higher density, greatly reduce the volume of rubber powder, not only can directly be distributed to fast in pitch, and pass through high temperature desulfurizing because of particle, cross-linked network is most of to be destroyed, as easy as rolling off a log and pitch is fused to one, at 160 DEG C, process dispersion, because the pollutent of generation having been carried out to vacuum removal in pyroprocess, and pitch is not volatile at 160 DEG C, the flue gas of pitch greatly reduces like this, rubber volatile component reduces greatly, thereby gas contamination is reduced greatly.
What is more important, owing to containing polyolefin elastomer in this desulfurization particle, less (the about 0.91g/cm of its density
3) and contain a large amount of active lateral groups, extruding rubber powder generation Chemical bond easy in sweetening process and that density is large, reduce rubber powder and the sedimentation in pitch certainly.Because polyolefin elastomer has excellent processing characteristics, high temperature performance and ageing-resistant performance, it can supplement the performance degradation that rubber powder is degraded and caused at high temperature desulfurizing with in heated bitumen greatly simultaneously.
The preparation method of a kind of environmental protection stable form rubber asphalt of the present invention, after the auxiliary agent such as will give up rubber tyre rubber powder and stablizer mixes, carries out high temperature mixing desulfurization, devolatilization granulation with screw extrusion press, obtains desulfurization devolatilization particle; After being mixed with linking agent, this particle add pitch to be prepared into rubber asphalt; This rubber asphalt is for water-proof tack coat, asphalt and stress absorbing layer.The part by weight scope of described pitch and desulfurization devolatilization particle is: 70～80:30～20.
In the present invention, rubber powder used is the fine powder of truck waste tire rubber goods processing and grinding, and order number is 10～80 orders; Stablizer used is polyolefin elastomer, is specially ethene and alhpa olefin copolymer elastomer, accounts for 10～30% of rubber powder weight; Adjuvant used is tenderizer, and wherein tenderizer is furfural extract oil, accounts for 3～20% of rubber powder weight; Linking agent used is sulphur, and linking agent weight is 0.2～5% of desulfurization devolatilization particle.
The preparation method of desulfurization devolatilization particle of the present invention, that rubber powder and stablizer, auxiliary agent are mixed at 20～100 DEG C of temperature, then the forcing machine of mixture being produced with reclaimed rubber desulfurize, at 180～250 DEG C of temperature, extrude, the end of forcing machine is provided with vacuum volatilization device, the material of after devolatilization, forcing machine being extruded causes desulfurization devolatilization particle by die face cutting equipment, and wherein desulfurization devolatilization particle is of a size of 2～6mm, and density is 0.8～1.1g/cm
3.
By adding pitch after desulfurization devolatilization particle and linking agent mixing, within 10-30 minute, be prepared into rubber asphalt at 120～160 DEG C of temperature down cuts.Can be used for water-proof tack coat, asphalt and stress absorbing layer.Under high temperature with respect to traditional rubber asphalt more than 180 DEG C, prepare pitch, need special premixing tank and heating unit, therefore there is advantages such as investing little, energy-conservation and environmental protection.
The advantage that the present invention prepares rubber asphalt is:
(1) loose rubber powder being extruded to kneading becomes particle, and rubber powder is compacted rear volume and obviously reduces, and has greatly improved the density of rubber powder, and the density of its density and pitch is approached, and is not easy to swim in asphalt surface.After rubber powder granulating, the viscosity rise of pitch is not obvious, and under stirring action, particle easily enters in pitch, has greatly saved the time of mixing with pitch.Less with the mixed viscosity increase of pitch, when passing through after cutting mill, rubber powder just mixes with pitch, absorbs fast the oil content in pitch, and viscosity obviously raises, and temperature also raises under shearing action, has obtained qualified rubber asphalt.
(2) by rubber powder high temperature desulfurizing extrusion, realize the desulfurization degraded of rubber powder, by the powerful shearing force of screw extrusion press, make rubber powder issue reducing of untreated rubber powder particles at comparatively high temps, disconnected sulphur and the desulfurization of rubber powder, thereby make its more easily swelling and reaction in pitch, easier and pitch becames one.
(3) because reaction extrusion is through high temperature desulfurizing, devolatilization process, very easily low temperature dispersion in pitch of particle, pollutent is eliminated in high temperature desulfurizing process simultaneously, can realize low-temperature environment-friendly processing.
(4) in rubber powder pyroreaction desulfurization extrusion, there is combination with the little polyolefin elastomer of density, polyolefin elastic can play stabilization has reduced on the one hand the subsidence rate of rubber powder, improved package stability, high performance polyolefin elastomer is given rubber asphalt good elasticity performance and resistance to shelf characteric on the other hand.
