Description
Technical field
The present invention relates to a kind of road bitumen, particularly a kind of pitch with modified from waste tire rubber powder the invention still further relates to this bituminous preparation method with modified from waste tire rubber powder.
Background technology
Rubber powder modified asphalt has just begun research and application as far back as the sixties in last century.Charles McDonald early start uses waste rubber powder modified asphalt, is used for the usefulness that road is repaiied the shop, is referred to as asphalt rubber (asphalt-rubber AR).The eighties begins a large amount of research and development later on, and the nineties is used widely in highway's surfacing later.Explore through long-term, verified rubber powder modified asphalt is laid highway and had series of advantages: production technique is easy, cost is low; Raw material sources are abundant, and are cheap; Construction technology is identical with plain asphalt; The road surface of laying has advantages such as good stability, wear-resisting, durable, antifreeze, anti-skidding, noise reduction sound and maintenance cost are low.Its cost performance has very remarkable advantages, has therefore obtained using widely.And with the pitch of shoddy modification, can waste rubber be utilized fully, help eliminating environmental pollution, can also improve the performance of bituminous pavement simultaneously.
But shoddy is through the sulfurized rubber powder; Generated three-dimensional space network through chemical bond; And containing carbon black and various additive, composition is very complicated, than more difficult swelling and the dispersion in pitch of general simple linear polymers such as primary rubber powder (like SBR, NR, BR etc.), plastics (PE, PP, EVA etc.) and thermoplastic elastomer SBS commonly used; Therefore can cause the package stability of waste rubber powder modified asphalt very poor, the effect of modifying asphalt is limited.So, be to make the shoddy degraded with shoddy to the key issue that pitch carries out modification, so that can uniform and stable being dispersed in the pitch.
To the problems referred to above, main several method below proposing in the external patent document makes the rubber powder degraded with technology: in the patent No. is the patent document of US6387965, propose, shoddy and organic solvent or aromatic hydrocarbon oil stirring under 150-300 ℃ are made its degraded; In the patent No. is the patent document of US5704971 and US5851276, propose, shoddy is mixed with hydrogen peroxide, utilize its strong oxidizing property, make the rubber powder degraded.When but these methods all existed price height, complex process and shoddy degraded, the problem of deterioration also can take place in asphalt performance.In the patent No. is the patent document of WO9414896 and WO9728220, propose, the rubber powder of high level is joined in the pitch, be mixed with high density performance pitch, the rubber powder modified asphalt of the package stability that can obtain degrading through high speed shear and high temperature.But the stability in storage with the waste rubber powder modified asphalt of this method preparation still remains to be improved.And the someone proposes to utilize the desulfurization of various shoddies to obtain the desulfurization rubber powder, then the desulfurization rubber powder is mixed with pitch and other composition high speed shear.For example in the patent No. is the patent document of ZL03134620.0, propose, microwave desulfurization rubber powder, styrene-butadiene rubber(SBR) and auxiliary component and pitch high speed shear are mixed rubber powder modified asphalt; In the patent No. is the patent document of CN1441005A, disclose a kind of preparation method of desulfurization glue powder-modified asphalt: epoxidation polybutylenes, GMA, SY-Monomer G or maleic acid improve desulfurization shoddy bituminous stability in storage.Perhaps, the patent No. proposed in being the patent document of ZL200410050792.X; Shoddy is through the coupling agent surface-treated; To strengthen the method for its dispersion stabilization in pitch; In the patent No. is the patent document of ZL200310104905.5, proposed, thereby added rubber improves the stability in storage of shoddy in pitch under the effect of linking agent method.But the loaded down with trivial details complicacy of method technology of above-mentioned waste rubber powder modified asphalt, but also need to add phase solvent or polymkeric substance, this makes production cost higher; In addition, shoddy improves stability in storage under the effect of coupling agent, but the addition of shoddy is limited, and cost is improved.
Summary of the invention
The objective of the invention is provides a kind of cost lower to above-mentioned deficiency, and preparation technology is simple, and can the good pitch with modified from waste tire rubber powder of stability in storage.
Another object of the present invention provides this bituminous preparation method with modified from waste tire rubber powder.
A kind of pitch with modified from waste tire rubber powder, it is mixed with by the following raw materials in parts by weight number and forms: the waste-tyre rubber-powder after the modification is 15-40 part, pitch 60-85 part; Waste-tyre rubber-powder after the wherein said modification is mixed with by the following raw materials in parts by weight number and forms: waste-tyre rubber-powder 84-97.8 part, heavy distillate 2-14 part, auxiliary agent 0.2-2 part.
The particle diameter of said waste-tyre rubber-powder is the 5-100 order.
The particle diameter of said waste-tyre rubber-powder is the 10-40 order.
Said auxiliary agent is one or more the mixture in sulphur, the agent of shortization of rubber.
Said heavy distillate is a kind of in long residuum, fluid catalytic cracking decant oil or the lubricating oil.
A kind of bituminous preparation method with modified from waste tire rubber powder, its step comprises:
1) be after the heavy distillate of 2-14 part is heated to 90-130 ℃ with parts by weight, the waste-tyre rubber-powder and the parts by weight that add parts by weight and be 84-97.8 part are the auxiliary agent of 0.2-2 part, mix then;
2) mixture in the step 1) is acted on 3-10 minute under microwave exposure and carry out desulfurization, obtain the waste-tyre rubber-powder after the modification;
3) under 160-200 ℃, adding parts by weight in the waste-tyre rubber-powder after parts by weight are the modification of 15-40 part is the pitch of 60-85 part, mixes;
4) with the mixture of step 3) 160-200 ℃ of following high speed shear, the mixture that obtains is the pitch with modified from waste tire rubber powder.
The particle diameter of said waste-tyre rubber-powder is the 5-100 order; Said auxiliary agent is one or more the mixture in sulphur, the agent of shortization of rubber; Said heavy distillate is a kind of in long residuum, fluid catalytic cracking decant oil or the lubricating oil.
Said step 2) mixture temperature is controlled at 150-180 ℃ in.
Said step 2) microwave frequency is 915 or 2450MHz in.
High speed shear in the said step 4) is with mixture under the rotating speed of 5000-10000rpm high speed shear 20-50 minute.
It is raw material that the present invention selects junked tire for use, is because junked tire is made up of vulcanized rubber, zinc oxide, carbon black and rubber accelerator, has higher elasticity, erosion resistance, higher relatively intensity and thermostability.With waste-tyre rubber-powder desulfurization under the microwave exposure effect, swelling; Mix with road pitch subsequently; High speed shear prepares the pitch of modified from waste tire rubber powder; Not only solved rubber powder and in pitch, be difficult to swelling and dispersive problem, thereby the pitch package stability of rubber powder modified is improved through desulfidation.Simultaneously, the present invention has made full use of junked tire, and raw material is simple and easy to, and can save cost, has also eliminated environmental pollution simultaneously, has also improved the bituminous performance.And bitumen production technological process with modified from waste tire rubber powder of the present invention is simple, has very strong practicality.
