Abstract
A pavement repairing material 'Cuoliping' for the pavement of express way is composed of two components, which are proportionally mixed before them are applied. After it is applied to pavement, it can be solidified within tens min and quickly reach high strength (10-80 MPa).
Description
Technical field
The invention belongs to the polymer-function material field.Relate to a kind of simple and efficient cement concrete patching material-mistake upright flat and method for making and purposes.
Background technology
The speedway concrete pavement faulting of slab ends is a general phenomenon very, and it makes, and driving is beated, " nodding ", and causes the road surface fracture, sinks, and jeopardizes the safety of driving and operation, is the hang-up of speedway maintenance management.With quick cement or bituminous concrete or macromolecular material (comprising epoxy resin and polyurethane) is the common method of repairing faulting of slab ends.The subject matter that above method exists is 1) engineering time is long, and is low to the cohesion of former pavement concrete, can not carry out the thin layer repairing on former concrete, need destroy original layer of concrete, builds the leveling faulting of slab ends more again.Therefore, should technology easy, hardening time short, cohere the jail at present for the rigid pavement of faulting of slab ends how directly in former road surfacing, the concrete patching material of good, the good endurance of abrasion resistance again, this remains and waits the problem that solves both at home and abroad.
The purpose of this invention is to provide a kind of proprietary material-mistake upright flat and method for making and purposes with the very fast leveling of speedway faulting of slab ends
Summary of the invention
Wrong upright putting down is made up of bi-component, can solidify in dozens of minutes, and its solidification intensity rises to 10Mpa immediately, finally reaches 80Mpa, and its cohesion and abrasion resistance are all very good.Its manufacture method is simple, and is easy to use, can be with the rapid leveling in faulting of slab ends road surface, and drop into normal the use immediately, and concrete structure had repair and protection and the comprehensive function that strengthens.It is to make speedway can accomplish the good material of meticulous maintenance, scientific management.
Wrong upright flat composed as follows:
The A component is formed: (by weight calculating)
Epoxy resin 100
Furfural acetone resin performed polymer 5-10
Inorganic filler 20-30
Through chemically treated SiO
240-55
The B component is formed (by weight calculating)
Varies 20-25
The inorganic material 20-30 that adds
Through chemically treated SiO
245-60
The weight ratio of A component and B component is: 2: 1.
Wherein, the present invention also provides furfural acetone resin performed polymer and chemical treatment SiO
2The preparation method.The preparation method of furfural acetone resin performed polymer, this method is mixed by 10: 4.0 weight ratio by furfural and acetone, adds 0.05～0.15% the NaOH that accounts for gross weight and makes catalyzer, stirs down normal temperature or 40 ℃, reaction is to boiling, and product is the furfural acetone resin performed polymer.Can use after the cooling.
Chemical treatment SiO
2Concrete preparation method will be through washing, dry, the SiO of sieve (≤40 order)
2, handle with the surfactant of weight 0.1%.For making the full and uniform distribution of surfactant energy, can be earlier with adequate amount of ethanol or acetone diluted.
In addition, epoxy resin set forth in the present invention be two officials of bisphenol A-type roll into a ball can and/or multi-functional epoxy resin; Varies can be fatty amine, acid amides and arylamine and compound thereof; Surfactant can be selected multiple silicone surfactant for use.Inorganic filler is selected from titanium dioxide, dry powder, feldspar powder, dolomite dust or calcium carbonate etc.
Technique effect of the present invention is 1) epoxy resin with contain α-active H, hydroxyl-OH and-the furfural acetone resin performed polymer of C=C-, varies, under the catalytic action of highly basic, generate induration rapidly with space network; 2) in pre-reaction, discharged the part heat thereby reduced heat in the overall reaction hurried and produce sudden and violent poly-may; 3) use of varies can be controlled in the bigger scope amine amount of adding, and is easy to use; 4) adding of surfactant has improved the surface affinity of organic material and inorganic material.Above technical design makes cement concrete patching material of the present invention have good physical and mechanical property and operating characteristics.Now as follows with the main mechanical property contrast of ordinary concrete, steel fiber feinforced cement mortar, ordinary mortar:
The wrong main mechanical property of putting down of standing of table 1 with ordinary concrete, steel fibre mortar, ordinary mortar
| Test item | Unit | Testing result | |||
| Wrong upright flat | Ordinary concrete | The steel fibre mortar | Ordinary mortar | ||
| Compressive strength | MPa | ?58.3(3d) | ???18.3(3d) | ??35.0~56.0 | ??43.7(3d) |
| Rupture strength (bending) | MPa | ?21.3(3d) | ???2.8(3d) | ??5.5~26.0 | ??7.0(3d) |
