Description
Technical field
The invention belongs to highway crack repair materials and preparation method thereof technical field, be specifically related to a kind of matrix material repairing highway crack and preparation method thereof.
Background technology
Crack is that road surface is the most common, one of the most incident early disease.Although the use properties of crack to highway pavement that Road surface Initial produces has no significant effect, along with extension and the expansion in crack, road surface will accelerated deterioration and badly damaged.Simultaneously, if process the crack that highway pavement occurs not in time, rainwater is under fracture void infiltrates and accumulates in road surface base plate, under traffic load repeated action, the rainwater accumulated and roadbed effect produce purt mud phenomenon, cause road to have to heavily spread or overhaul, the generation of traffic accident will be caused time serious, cause personnel and property damage.
At present, the material of squeegeeing that redeck adopts mainly contains: heated bitumen class, bitumen emulsion, proprietary material class etc.Wherein, heated bitumen class squeegees that material has that temperature sensitivity is large, energy consumption is large in use procedure, cohesive force is not enough, construction time and the shortcoming such as the road closure time is longer and lower temperature resistance is poor; The shortcomings such as emulsified bitumen class gap-grouting material has that adhesive property is poor, moisture is not volatile, solidification is slow and the road closed time is long; And proprietary material class gap-grouting material exist viscosity too large, fully should not infiltrate crack, need to add the shortcoming such as a certain amount of organic thinner and feature of environmental protection difference in use.
Urethane road surface material of squeegeeing has that soft or hard is adjustable, set time is adjustable, viscosity is low and cohesive strength advantages of higher, avoids pavement excavation, repair time is long and affect the problems such as traffic.Use urethane pavement crack repair materials, can obviously save roadupkeep cost, improve maintenance efficiency, be the economy in maintenance of surface and effective means.
Publication number CN102516492A discloses a kind of two-component polyurethane grouting material for road maintenance maintenance and preparation method thereof, low as there is viscosity during asphalt pavement crack-filling materials'use, solidification in 1 ~ 10 minute under normal temperature, and by the kind of catalyzer, the advantage of consumption adjustment solidification required time added, the problem of the long-time blocked road of road repair time need in the past can be solved.But this invention belongs to one and can to foam Embedding Material, and embedding post-foaming amount is uncontrollable, often foaming exceeds road surface, causes pavement crack place projection, the comfortableness of impact driving and the planarization of road, and the rear strength of materials of foaming is lower.
Publication number CN101885827 A discloses a kind of double-component polyurethane caulking agent for repairing road cracks, this caulking agent comprises polyol-mixture component A and base polyurethane prepolymer for use as component of mixture B, wherein component A counts by weight and at least comprises: polyether glycol 100 parts, ethylene glycol 5 ~ 20 parts, TriMethylolPropane(TMP) 0 ~ 10 part, 0.1 ~ 5 part, hydrogen peroxide, tin catalyst 0.0001 ~ 0.01 part; B component is the base polyurethane prepolymer for use as mixture prepared as follows: diphenylmethanediisocyanate and molecular weight be 300 ~ 3000 polyester polyol carry out polyreaction obtain base polyurethane prepolymer for use as by weight 100:30 ~ 80, then the ferrous salt of this base polyurethane prepolymer for use as with 0.1 ~ 1wt% based on gross weight to be mixed.The advantages such as it is low that the present invention has viscosity, good penetrability, the strong and clean environment firendly of cohesive force.But the tensile yield of this invention is lower.
Publication number CN103540122A discloses a kind of carbon fiber reinforced polyurethane road and sews and mend material and preparation method thereof, can increase substantially the cold-resistant hot and weathering resistance that glue sewed and mend by urethane when sewing and mend materials'use as road surface; But it is in use owing to employing carbon fiber, running into small gap perviousness can be affected, and needs acetone to do solvent contamination environment in addition, and the impact certain on the healthy generation of workmen.
Publication number CN103613333 A discloses a kind of asphalt-base composite materials for pavement crack repair, and it is made up of following raw materials by weight portion ratio: component A: anionic emulsified bitumen 120 ~ 150 parts, water reducer 1 ~ 3 part, defoamer: 1 ~ 3 part, binding agent: 3 ~ 8 parts, water: 0 ~ 10 part; B component: cement 100 parts, sand 70 ~ 110 parts, swelling agent: 0.01 ~ 0.06 part.The present invention has the flexibility of pitch and the rigidity of cement, for the cementation of fissures, there is certain intensity transmission load force can be carried, add binding agent in material and play the effect of cohesive force between strongthener and slotted wall and pavement life is extended not easily occur cracking phenomena again.Simultaneously the present invention have cheap, construction is simple, low to the requirement of workmen, consume energy low, that cohesive force is strong, permanently effective advantage, can be widely used in the repairing of crack on road.But the pavement crack repair materials described in this invention is long for set time, and the road closed time is long, affect the current smoothly of vehicle.
Publication number CN103589390 A discloses a kind of pavement crack repair material and preparation method thereof, comprises following component by mass percentage: petroleum pitch 35 ~ 65%; Properties-correcting agent 6 ~ 12%; Unique edge corner material powder 6 ~ 10%; Softening agent 2 ~ 5%; Softening oil 8 ~ 15%; Waste Crumb rubber 10 ~ 25%; Tackifier or nano-oxide 3 ~ 10%; Described unique edge corner material powder is the scrap stock of Cowhells sole and chloroprene rubber, to grind form according to the mass ratio of 3:2.5 through masher.The present invention has the splitting resistance of good low temperature, the stability of high temperature, the cohesiveness at interface, resistance to deterioration and anti-fatigue performance, is suitable for pitch under the cold climate conditions of pole or the crack of cement concrete pavement and the repairing of seam.But there is the slow deficiency of sclerosis equally in this invention product.
Publication number CN103361026 A discloses a kind of pavement crack repair material and preparation method thereof, it is characterized in that a kind of when being under pressure impact, namely there is recoverable deformation, also there is viscous deformation simultaneously, viscous deformation can consume most striking energy, and the portion of energy that recoverable deformation is put aside can make material slowly return to the material of the shape before pressurized after external force is removed, by microcellular polyurethane elastomer surface material, fiber reinforced material and sizing agent composition, this material can stand to drive a vehicle the power of expanding with heat and contract with cold in the shearing force that causes and crack self for a long time, repair efficiency maintains more than 5 years.This invention is the technical scheme of long, convenient, low-carbon environment-friendly, the cost performance much higher purposes pavement crack repair material of constructing of a kind of life-span and preparation method thereof.This material belongs to a kind of veneer restorations material of adhesive bandage formula, and this crack patching material can make it reduce with the cohesiveness on road surface because of expanding with heat and contract with cold, and even can come off, come out again in crack under the shearing force repeatedly and pressure effect of wheel.
