Description
Technical field
The invention belongs to pavement construction material field, relate to a kind of preparation technology and preparation method of road engineering bioconjugation material modified asphalt material.
Background technology
At present, the petroleum pitch of the binder used in bituminous pavement mostly for refining from crude oil, due to overexploitation and use, petroleum resources will be petered out.The present situation of petroleum resources and environmental development problem force the equivalent material of the continuous search for oil asphaltic binder of road investigator.Due to bioenergy comparatively fossil energy compared the features such as recyclability, the feature of environmental protection and economy, generally believe that bioenergy solves energy starved main method from now on both at home and abroad.Compared with petroleum pitch, bioconjugation material is similarly the product of the biological material course of processing, is refuse and the residue of biological industry, is obtained by complete processings such as the distillation of biological material, extraction, blending and oxidations.Bioconjugation material and petroleum pitch character close, using bioconjugation material as petroleum pitch substitute or material modified, both can realize the recycling of new forms of energy chemical field waste material, again for new developing direction opened up by road novel material.
Pitch is typically used as paves the way and water-proof material, belongs to a kind of thermoplastic material in essence.The road surface of asphalt paving used now by this property list, during summer high-temperature season, under heavy lift effect easily there is rut in road surface, easily warm plastic forming is there is during cold season in winter, along with the raising of road quality classification and the generally employing of Large-span Steel Box Beam structural bridge, very high requirement is proposed to the intensity of pavement material, deformation stability and fatigue durability etc., in use properties, also been proposed high agglutinating value(of coal) and the particular requirement such as waterproof simultaneously.As the important component part of bridge car system, the quality of deck paving directly has influence on the security of driving, comfortableness, bridge durability and economic benefit of investment.Obviously, so high performance requriements is that plain asphalt institute is incompetent, must use modifying asphalt.Although most of bioconjugation material has certain plasticity-and cohesiveness, and supporting capacity is general.
The bioconjugation material of usual employing derives from sawdust and the agroforestry such as stalk, rice husk by product or waste, although the Biological asphalt prepared to a certain extent can petroleum replacing pitch, but because in these waste materials, heavy ingredient is more, can affect greatly aspects such as the petroleum pitch low-temperature performancies mixed with it.This is very disadvantageous for this kind of Materials.Chinese patent CN1276820A discloses the made paraffin modification pitch of employing expense-holder synthesis method, but the shortcoming of this method to be the low-temperature performance of modifying asphalt bad, its use is subject to great limitation.Chinese patent 01126386.5 reports and adopts the filler of nucleocapsid structure independent or composite with polymkeric substance, as asphalt modifier to prepare the modifying asphalt of shelf-stable, but this method complicated process of preparation, production cost is high.
Summary of the invention
First object of the present invention is the deficiency that non-renewable petroleum pitch resource is petered out in order to solve, waste and scrap recycles problem and common Biological asphalt low-temperature performance aspect, and provides a kind of road engineering bioconjugation material modified asphalt material.
Second object of the present invention is to provide that a kind of preparation method is simple, the preparation method of the road engineering bioconjugation material modified asphalt material of handling ease.
For reaching above object, the present invention adopts following technical scheme to realize.
Raw material of the present invention is formed with parts by weight proportioning by bioconjugation material and petroleum pitch, and wherein, bioconjugation material weight percent is 5%--35%, and the weight percent of pitch is 65%--95%.
Bioconjugation material source is cottonseed and soybean, by resistates after refining grease through chemical technologies such as distillation, oxidations, and the appurtenant of acquisition.
The SBS modifying asphalt that petroleum pitch model is No. AH50, be matrix pitch modification with No. 70 pitches.
The road engineering preparation method of bioconjugation material modified asphalt material, specifically comprises the steps:
Step 1, respectively bioconjugation material and petroleum pitch are heated to 115-145 DEG C, make bioconjugation material and petroleum pitch have good mobility.
Step 2, take bioconjugation material and petroleum pitch in step 1.Carry out proportioning according to weight, wherein, bioconjugation material weight percent is 5%--35%, and the weight percent of petroleum pitch is 65%--95%.
Step 3, by thermostatically heating equipment, the blend temperature of bioconjugation material and petroleum pitch is maintained within the scope of 130--190 DEG C, adopt high speed shear emulsifying device with the blend 15--60min of the rotating speed high speed shear bioconjugation material of 500rpm--4000rpm and petroleum pitch, the blend of bioconjugation material and petroleum pitch is made to continue to grow by the mode stirred again, until the bubble mixed in blend disappears substantially, obtain finished product.
The mode stirred can be mechanical stirring equipment stirring at low speed, high-speed shearing equipment stirring at low speed or artificial Keep agitation or be manually interrupted.
The present invention has following useful technique effect:
1) preparation technology of the present invention is simple, the bioconjugation material modifying asphalt produced can improve the low-temperature ductility of petroleum pitch, effectively improve the antifreeze resistance to cleavage of petroleum pitch under low temperature environment, can partly replace road petroleum pitch, the consumption of non-renewable petroleum pitch can be slowed down to a certain extent;
2) bioconjugation material of the present invention derives from the waste material in industrial production, cheap, effectively can realize waste material recycling,
3) the bioconjugation material adopted in the present invention, its starting material are reproducible Biological resources, abundance, and output is sufficient, environmental protection.
