Description
Technical field
The present invention relates to a kind of filling cut of asphaltum road surface glue and preparation method thereof, belong to petrochemical industry.
Background technology
Petroleum pitch is the residue of oil after atmospheric and vacuum distillation, and petroleum pitch has higher temperature sensitivity, and the easy deliquescing of high temperature, low temperature easily become fragile, and therefore, bituminous pavement easily ftractureed in the winter of northern area, occurred Permanence Pavement crack.When rainy season set or ice dissolution, the meetings such as water are penetrated into by crack in the basic unit on road surface and go, and cause the destruction of sub-surface, significantly damage the work-ing life of bituminous pavement.
While adopting plain asphalt or modifying asphalt to repair asphalt pavement crack, pitch softening point is low, the phenomenon that high temperature is prone to bellding and is taken away by vehicle, during low temperature, pitch can become fragile again, easily come off, the stress that is difficult to stand the expansion of pavement crack low temperature, easily ftractures, and repairing is short work-ing life.Base joint grouting glue is to be exclusively used in the bituminous material that asphalt pavement crack is repaired, and has excellent high and low temperature performance and elastic recovery properties, can stand the flexible strain bringing in crack, extends and repairs work-ing life.
Chinese patent CN200810055524.5 adopts after water, aqueous adhesive, pitch, dispersion agent copolymerization, through macromolecular water-soluble resin and rubber latex modification, and a kind of embedding, joint seal material that the auxiliary agents such as admixture stablizer, thickening material form.The crack of bituminous pavement generally produces in the winter time and repairs, and water-based gap-grouting material is cold snap constructional difficulties in the winter time; The general viscosity of water-based gap-grouting material is low, the depth of penetration of wayward gap-grouting material; In water-based gap-grouting material, contain a large amount of water, these water cannot volatilize conventionally after construction, are persisted to road surface Xia Dui basic unit and have destruction.
Chinese patent application CN201010189080.1 adopts the material proportion of 10%-15% aromatic hydrocarbons, 3%-10% properties-correcting agent, 1%-3% organosulfur based compound toughener, 3%-10% inorganic chlorine based compound solubility promoter, 30%-60% petroleum resin mixture, heavy traffic paving asphalt 10%-20%, preparation method is first heated to aromatic hydrocarbons 60 ℃～70 ℃, then adds properties-correcting agent stir about 30 minutes; Progressively slowly add again toughener and fusing assistant; Finally resin and pitch are added, be incubated 120 ℃, in the situation that stirring, keep preparing for 30 minutes the base joint grouting glue of resin type.Resene gap-grouting material low-temperature performance is poor, be not suitable for northern cold climate, the physical index of the resin fissures cementation glue that this patent provides is: 5 ℃ of ductility >30cm, softening temperature >70 ℃, recovery of elasticity >75%.According to the JT/T740-2009 of domestic communication portion product standard, the low-temperature performance of base joint grouting glue is adopted to cryogenic tensile index, but not 5 ℃ of stretch indexes; Softening temperature requires >=80 ℃; Recovery of elasticity requires 30% ~ 70%.Preparation method's flow process of this Patent Application Publication is longer, is unfavorable for suitability for industrialized production.
