Abstract
The present invention provides a stabilizer composition for polymer modified asphalt; the stabilizer composition consists of a dispersion stabilizer and a crosslinking reactant, wherein the dispersion stabilizer consists of an acid substance and polyol ester, the mass fraction of the dispersion stabilizer is 10-90%, the crosslinking reactant is one or a mixture of more than one of sulfur and compounds thereof, peroxide and inorganic metal oxide, the mass fraction of the crosslinking reactant is 10-90%, the stabilizer composition can be directly used in the production process of the polymer modified asphalt, and can be sequentially added during physical shearing grinding or after the shearing grinding is finished, the addition amount accounts for 0.1-2% of the total amount of the polymer modified asphalt, and after the stabilizer composition is added, the polymer modified asphalt has good storage stability, and the prepared modified asphalt has excellent high and low temperature performance.
Description
Technical field
The present invention relates to a kind of preparation for polymer modified asphalt, particularly the preparation process of the stablizer of polymer modified asphalt.
Background technology
Compare with cement concrete pavement, bituminous pavement have surfacing, without seam, the driving comfortable, wear-resisting, the advantages such as vibration is little, noise is low, the construction time is short, simple maintenance, thereby the acquisition more and more widely the application.Along with the develop rapidly of economy, the highway mileage of China will increase year by year, take in Xinjiang as example, highway mileage will double during following " 12 ", simultaneously, along with the increase of traffic flow, the maximization of vehicle, also more and more higher to the specification of quality of bituminous pavement.Plain asphalt is the stronger material of a kind of temperature sensibility, in the time of near temperature is reduced to brittle point, pitch is vitreous state, lose flexibility, embrittlement very easily occurs in compound, causes the road surface crack to occur, when running into the rainy day again, rainwater causes pitch and sandstone to come off and causes Moisture Damage from crack infiltration compound, causes the road surface groove to occur cheating; Then become viscous state in the time of near temperature rises to softening temperature, lose visco-elasticity, this moment, the stiffness of pitch was very little, and compound is yielding under external force, caused the road surface that rut occurs or gathered around the harm such as bag.Therefore, it is large that plain asphalt has been difficult to satisfy the special bus flow, and the speed of a motor vehicle is fast, the requirement of the extreme weathers such as load is heavy and high and cold, high temperature.Modifying asphalt is as the road surface novel material, pitch is all improved at aspects such as temperature sensibility, stability, weather resistance, adhesivity, resistance to deteriorations comprehensively, can improve the comprehensive use properties in road surface, especially SBS modifying asphalt, can satisfy simultaneously the high temperature performance requirement, have again the advantages such as suitability is wide, become the main force in the modified bitumen product.
But, because polymkeric substance and pitch are in many difference of the aspects such as molecular weight, density, polarity, solubility parameter and other physics, chemical property, cause the consistency between polymkeric substance and the pitch very poor, thereby polymkeric substance is very easily separated from modifying asphalt, do not reach the purpose of polymer modified asphalt, the most polymers modifying asphalt can only be produced at the scene.Although need not consider the problem of polymkeric substance segregation when taking situ production, job mix, but site production of modified asphalt one is having relatively high expectations to equipment, investment is large, the 2nd, only be simple physical mixed between polymkeric substance and pitch, the performance of modifying asphalt does not often reach the requirement of standard, pavement life is shorter, therefore how to realize the batch production production of modifying asphalt and guarantees that the high-temperature storage stability of modifying asphalt becomes the focus of in recent years polymer modified asphalt research.
For this problem, people have mainly done a large amount of research work around the type of the preparation technology of modifying asphalt, polymer modifiers, matrix pitch, stablizer.In the middle of aspect these four, most study for stablizer, this is because will prepare high temperature storage stable, the satisfactory polymer modified asphalt of performance, adopt which kind of technique no matter be, use which kind of properties-correcting agent or matrix pitch, all need in the modifying asphalt system, to add dissimilar stablizers.
At present, use more stabilizer types can be summarized as four classes.The first kind is sulphur and compound thereof, mainly is the organic sulfides such as elemental sulfur and thiazole, thiuram; Equations of The Second Kind is acid, mainly is mineral acid, such as sulfuric acid, phosphoric acid etc.; The 3rd class is superoxide, and benzoyl peroxide (BPO) and dicumyl peroxide (DCP) etc. are typically arranged, and the 4th class is metal oxide, and calcium oxide, magnesium oxide, aluminum oxide and zinc oxide etc. are typically arranged.Using more in this four classes stablizer is sulphur and compound thereof, it is cheap and easy to get that it has raw material, rate of crosslinking is fast, the advantages such as applied range, but the add-on of sulphur and adding speed are very large on the impact of reaction result, and disposable adding sulphur is too fast or too much, can make asphalt-polymer occur excessively crosslinked and are condensed into colloid, cause flow difficulties, can't continue to produce.
For solving the bad problem of polymer modified asphalt package stability, and used sulphur-containing stabilizer exists crosslinked inhomogeneous, the easy gelation problems of overvulcanize effect, make linking agent with sulphur among the WO984537, take the mode that repeatedly adds slowly, cause processing step loaded down with trivial details, course of processing length consuming time, therefore, treatment capacity is restricted; CN1644625 discloses a kind of modifying asphalt for high-grade highway, dam and preparation method thereof, modifying asphalt is comprised of package waste polymer PE, matrix pitch, dispersion agent, tensio-active agent, its dispersion agent is pentaerythritol stearate, tensio-active agent is the polyvinyl chloride sorbitan ester, this stablizer is the stablizer without sulphur, can avoid the gelation problems because of overvulcanize effect generation, but narrow application range makes it not possess popularity; CN101173072 provide equally a kind of for polymer modified asphalt without the sulphur stabiliser composition, comprise EVA and P contained compound, can directly add in the pitch, can prepare the polymer modified asphalt with good high-temperature storage stability, but because having used a large amount of P contained compounds, the low-temperature performance of modifying asphalt is not fine; It is a kind of main by composite stabiliser composition that forms such as vulcanization crosslinking agent, crosslinking accelerator, dispersion agents that CN1408750 provides, this stabiliser composition is under a kind of parcel of fatty acid amide dispersion agent, can make linking agent evenly spread to rapid reaction in polymkeric substance/bitumen dispersions system, avoided the formation of gel, and can make polymer modified asphalt have better stability in storage; CN101628989A is take sulphur as the main reaction agent, take aromatic hydrocarbons viscous crude class as dispersion agent, by reaction promoter is dissolved in the dispersion agent, promoted the mixing uniformity of reagent and reaction promoter, also increased simultaneously the homogeneity of stablizer and matrix pitch reaction, avoided partial cross-linking excessively to produce the phenomenon of caking, but the stabiliser composition of mentioning in above two patents to prepare in advance and could use complex technical process.
