Description
Technical field
The present invention relates to modified asphalt technology field, especially a kind of water-base epoxy asphalt waterproofing bonding layer material and system thereof
Preparation Method.
Background technology
China's bridge deck water-proof tack coat material great majority in early days are changed by architectural waterproof material, therefore its point
Class situation is roughly the same with architectural waterproof material.Mostly with Colophonium for substrate material in present stage China's water-proof bond material for bridge deck pavement
Material, mainly includes roll of material and coating class.
China's highway bridge floor water-proof tack coat is main based on common emulsified asphalt before calendar year 2001, typical project
Having and rather connect at a high speed, but later stage engineering practice proves, the type water-proof tack coat can not meet pavement performance requirement.
In recent years, China has also carried out research and the engineer applied of various new water-proof binding layer material, mainly has high score
Sub-water-base epoxy Colophonium, bituminous epoxy, epoxy resin, emulsion epoxy resin, single-component epoxy Colophonium etc..Novel epoxy class is waterproof
Bonding layer material indoor performance is excellent, and main experimental section engineering includes that Su-Tong Brideg access bridge part uses bituminous epoxy water-proof binding
Layer, sea, river highspeed portion bridge floor use bituminous epoxy and epoxy resin water-proof tack coat.Show according to achievement in research, use novel
The pave-load layer behaviour in service of water-proof tack coat is good.
According to national planning, being up to 10.8 ten thousand kilometers to China's highway in 2015, network of highways total kilometrage reaches 450
Ten thousand kilometers, pavement construction material market is the hugest, and highway increases by 10,000 kilometers according to average annual, network of highways total kilometrage according to
Average annual growth by 100,000 kilometers, then bridge mileage calculates according to 20%, calculates according to two-way 4 tracks, freeway bridge over the nearlyest 3 years
Face construction of waterproof layer area reaches 27,000,000 squares, and state's provincial highway arterial highway construction area reaches 2.7 hundred million squares.
Therefore, extend the service life of bituminous epoxy water-proof tack coat the most further, reduce cost, increasingly gone
Attention in the industry.
Chinese invention patent CN102321372A disclose a kind of Waterborne polyurethane epoxy resin modified emulsified asphalt and
Preparation method, the indices of this emulsified asphalt is superior to the most common modified emulsifying asphalt, has good low tenderness
Toughness and high-temperature stability, use for maintenance of surface or the binding material do not stopped as preventive maintenance and pit-hole.But should
Emulsified asphalt relatively costly, and still have much room for improvement its service life.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of water-base epoxy asphalt waterproofing bonding layer material
And preparation method thereof.
A kind of water-base epoxy asphalt waterproofing bonding layer material, including the composition of following percentage by weight:
Epoxy curing agent aqueous solution 5-15%
Nanoscale expanded vermiculite powder 0.2-0.5%
Aqueous polyurethane epoxy resin 15-25%
Emulsified asphalt 35-45%
Quartz sand 20-30%
Graphene 0.001-0.002%
Sodium polyacrylate surplus.
Preferably, the solid content of described emulsified asphalt is 50-55%.
Preferably, the particle diameter of described quartz sand is 500-800 μm.
Preferably, the particle diameter of described nanoscale expanded vermiculite powder is 30-80nm.
The preparation method of a kind of water-base epoxy asphalt waterproofing bonding layer material, comprises the following steps:
A, the preparation of epoxy curing agent aqueous solution；
B, the preparation of aqueous polyurethane epoxy resin；
C, sodium polyacrylate is dissolved in water, adds nanoscale expanded vermiculite powder and Graphene, exist with high speed dispersor
High speed dispersion 2-3min under conditions of 3000-5000rpm；
D, epoxy curing agent aqueous solution, aqueous polyurethane epoxy resin, emulsified asphalt, property-modifying additive and quartz sand are mixed
Water-base epoxy asphalt waterproofing bonding layer material is i.e. obtained after closing uniformly.
It is swollen that the present invention adds quartz sand, nanoscale on the basis of traditional water-base epoxy asphalt waterproofing bonding layer material
Swollen vermiculite power and Graphene.
The purpose adding quartz sand is to increase the intensity of bonding layer material, and the repair to crackle is good, has blocked cement
Concrete surface capillary hole, has stopped the generation of " whiting " phenomenon.
And add nanoscale expanded vermiculite powder and mainly have the effect of two aspects, one is that it has layer structure, has non-
The best impact resistance；Two is owing to the price of Graphene is higher, and it is that the dispersion of Graphene provides template, only needs to add
The Graphene of trace, at utmost increases the surface area of Graphene while low cost, plays the performance of Graphene.
And the Main Function adding Graphene has: one be Graphene be the thinnest material, be also the most tough material, fracture
Taller 200 times of the steel that strength ratio is best, it has again good elasticity simultaneously, and stretch range can reach the 20% of own dimensions,
It is the material that current nature is the thinnest, intensity is the highest, adds Graphene and can be greatly increased intensity and the toughness of material, and improves
Water proofing property.
And Graphene combines with nanoscale expanded vermiculite powder and also has extraordinary flame-retardant smoke inhibition effect, if it occur that fiery
Calamity, expanded vermiculite powder can be with absorbed portion volatile material, and Graphene is attached on nanoscale expanded vermiculite powder, due to graphite
The aperture of alkene is the least, and volatile material cannot evaporate in air through Graphene, presses down cigarette function well, and material outer layer
Oxygen also is difficult to cross Graphene and enters material internal, so having cut off the oxygen needed for material internal burning, it is the best to play
Fire retardation.
Having the beneficial effect that of the preparation method of the present invention
1, material dosage form is advanced.This material is W/O structure, and Surface Permeability is good, and crackle is had repair.Meanwhile, block
Cement Concrete surface capillary hole, has stopped the generation of " whiting " phenomenon.Parcel surface particles, the tolerance to Cement Concrete surface cleaning
High.Modest viscosity, stable, during spread, sprayability is good.Environmental protection, does not use organic solvent.
2, excellent material performance.This material at low temperature pliability is excellent, and high-temperature behavior is good, does not feels like jelly, the most tacky.Mechanical property
Brilliance, shear strength, adhesion strength are greatly improved.Impermeability is strong, and anti-to press against brokenly pierceability good.Durability is strong, and freeze thawing resistance-water damages
Good cycle is alkaline-resisting good with salt water resistance corrosivity.
3, workability is advanced.Easy construction, does not spread rubble, identical with spread adhesion coating emulsified asphalt, and room temperature is constructed, energy-conservation
Environmental protection, rapid draing, climate adaptability is good.After drying can be with open to traffic.When heavy duty truck/crawler belt paver rolls, even if
At high temperature also non-scale in midsummer, not viscous wheel.
4, system easy to control the quality.In work progress, quality control index is single, it is only necessary to control spread quantity.
5, waterproof effect is excellent.Material itself does not seeps water, and after pave-load layer paves, intermediary water cannot ooze down, and moisture-locking is mated formation
Layer surface occurs without water stain.
6, cost is moderate.The cost of all kinds of waterproof material of Integrated comparative, water-base epoxy water-proof tack coat affordable, sexual valence
Than optimum.
7, service life is long, typically can reach more than 15 years.There is extraordinary impact resistance, intensity and toughness, simultaneously
Also there is good flame-retardant smoke inhibition effect.
