Description
Technical field
Present method relates to a kind of road bitumen properties-correcting agent, particularly polyurethane-type high temperature tracking-resisting modifier for a kind of road bitumen.
Background technology
Asphalt pavement rut is one of primary highway disease of China, it is under bituminous pavement car load repeated action, runway produces larger permanent deformation at the wheelpath place, and the pavement damage phenomenon of the similar groove of a kind of shape formed along vehicle heading on bituminous pavement.Rut generally occurs in the season that temperature is higher, and oil mat forms gradually in the lower generation tension set of repeatedly rolling of vehicle and VISCOUS FLOW.It the side direction protuberance occurs normally when following the oil mat compression subsidence.The appearance of rut, had a strong impact on work-ing life and the service quality on road surface, brought much harm to the pavement usage person: as affect the planeness on road surface, the security of reduction road-ability and goods; Pitch reduced thickness in the rut groove, reduce the pavement structure bulk strength, thereby be easy to bring out variety of issue, as check crack and Water Damage etc.; The rainy day Pavement surface drainage is not smooth, reduces the anti-slide performance on road surface, affects the safety of high speed traveling; Cause vehicle out of control when overtaking other vehicles or change direction, affect the stability of trailer reversing etc.
Anti-rut agent is a kind of multi-component Chemicals, adds shear strength or the non-deformability that can significantly improve bituminous pavement in pitch or its compound, thereby effectively stops or delay the generation of rut.Now widely used anti-rut agent is mainly organic and inorganic two large classes.Inorganic modified dose mainly comprises carbon black, diatomite etc., and organic modifiers is mainly Plastic, rubber-like and fiber-like, as polyethylene (PE), vinyl-vinyl acetate copolymer (EVA), styrene-butadiene rubber(SBR) (SBR) etc.Anti-rut agent product commonly used has French PRPLAST, the DUROFLEX of Germany and the rut king of Shenzhen Hai Chuan etc.This several prods is all to take polyethylene as main raw material, can significantly improve rutting-resistant performance of mixture, easy to use, but the selling price costliness, so it is applied and is restricted.Product high temperature elasticity is better in addition, but low-temperature performance is poor, and fragility is large, easily embrittlement and cracking, and the ageing resistance of product and antistrip performance are also poor.
Chinese patent CN 101063000A, CN 101165102A, CN 101857393A, CN 101906224A disclose the pitch physically modified agent of a class traffic anti-track, and such properties-correcting agent contains one or both in polyolefine and thermoplastic ethylene's base aromatic hydrocarbon-conjugated diene block copolymer (SBS class material), lignocellulose, rubber powder and oxidation inhibitor.Such properties-correcting agent can improve the rutting resistance of asphalt, but the flexural strength of compound only improves the 3Mpa left and right and stiffness modulus also only improves 15% left and right, and properties-correcting agent improves limited to the compound low-temperature performance.
Chinese patent CN 102181134A discloses a kind of anti-rut agent, bituminous material and preparation method, and anti-rut agent mainly is composited by urethane, polyethylene terephthalate, polymethacrylonitrile and calcium carbonate etc.Wherein urethane is the segmented copolymer that diphenylmethanediisocyanate and propylene glycol polycondensation form.Adopt this anti-rut agent make the dynamic stability of the anti-rut of high temperature of compound reach 10000 times/more than mm, but the properties-correcting agent addition accounts for 5%～15% of pitch gross weight, 5 ℃ of ductilities of pitch only can reach 2～5cm, show that this properties-correcting agent improves limited to the low-temperature performance of pitch.
The polyurethane chemistry modification is a kind of emerging asphalt modification method.The clear 62-50363 of Japanese Patent has announced a kind of method of road bitumen polyurethane chemistry properties-correcting agent.The base polyurethane prepolymer for use as that this patent adds the hydroxy-terminated polybutadienes polyvalent alcohol to react with polyisocyanates to make in the road matrix pitch is as chemical modifier, the elastomer latex that has then added the physically modified effect, thus this patent report should be the mixed modifier that a kind of polyurethane chemistry properties-correcting agent and the agent of elastomer latex physically modified are used simultaneously.In this polyurethane-modified pitch technology, the modifying asphalt softening temperature rises slowly, ascensional range is little, when common properties-correcting agent addition (5wt%), the leading indicator softening temperature only rises 7.1 ℃, with the SBS physically modified agent adopted, make pitch softening point improve 20 ℃ of left and right and differ larger, therefore the road bitumen by this modifier modification can not meet laying and the requirement in work-ing life of road under the severe weather environment of high temperature sweltering heat, and its use range is subject to certain limitation.
Russ P RU 2303613 C1 disclose a kind of method of modification of pitch being carried out with urethane, this method comprises active ingredient substance interaction in synthetic in advance polyurethane prepolymer and pitch, to generate urethane network structure in pitch, wherein prepolymer is to be made by polyvalent alcohol and isocyanate reaction.According to invention, the interaction of pitch and prepolymer is by being to realize by the method stirred in 0.25～1 hour in 60～140 ℃ of situations in temperature.Modified effect is to have obtained low temperature brittleness, water suction, the material that hot mastication, sticking power and tensile strength strengthen, and the corrosion stability material of improvement.The described properties-correcting agent of this patent, mainly for the sticking power to steel and the water-intake rate of pitch, do not relate to the anti-rut performance of high temperature of modifying asphalt, and the properties-correcting agent provided only can be increased to 50～64 ℃ by the softening temperature of pitch.
Chinese patent CN 102464892A has announced a kind of composite polyurethane modifier for road asphalt, its component comprises that the polyisocyanate prepolymers of NCO terminal or polymkeric substance, terminal hydroxy group are or/and amino compound, organic catalysts for polyurethanes etc. can form the component of polyurethane structural, and other property regulation component.This properties-correcting agent can improve matrix pitch softening temperature performance to approximately 70 ℃, and 5 ℃ of ductilities are to more than 20cm, and the modifying asphalt consistency of acquisition is good, excellent storage stability, modified effect are stable lasting.The process of this properties-correcting agent and matrix pitch hybrid process is simple simultaneously, processing temperature is low, thereby reduces energy consumption, low-carbon environment-friendly.This patent adopts polyisocyanate prepolymers or polymkeric substance reacts with chainextender in pitch and generates polyurethane structural, need synthesize in advance polyisocyanate prepolymers or polymkeric substance, complex technical process, and do not relate to the high temperature resistant anti-rut performance of modifying asphalt.
