Description
The present patent application is application number 201310026903.2, the applying date 2013 year 01 month 18 days, a kind of denomination of invention " water
The divisional application of cement concrete bridge floor waterproof material and preparation method thereof ".
Technical field
The present invention relates to a kind of waterproof material and preparation method thereof, the waterproof material and its system of particularly a kind of stable performance
Preparation Method.
Background technology
At present, the highway in China particularly expressway construction have developed rapidly.In constructing road, miscellaneous bridge
Occupy considerable part ratio in the total kilometrage of highway, for a long time, due to being paid little attention to the waterproof of cement concrete bridge deck,
Directly or carry out after simply improveing, roof waterpoof material is applied to bridge deck water-proof, often occurs such as grade separation in Practical Project
The problems such as bridge water permeating of bridge floor, pave-load layer peel off, floorings are broken.Bridge is caused to occur steel bar corrosion etc. due to the infringement of water resistance to
Long sex chromosome mosaicism, cause huge potential safety hazard and economic loss.Research shows, the infiltration of water is cause these to destroy most direct
One of with most important reason.The infiltration and delay of water, at temperature and load comprehensive function, not only cause surface layer it is loose,
Peel off and pit is destroyed, moreover, water leaking-in can cause basic unit's softening, intensity decreases, and then induce the more serious destruction of surface layer.
In order to protect floorings, prevent rut or crawler belt from directly wearing away bridge floor, and so as to disperseing the load of wheel, generally use cement
Concrete and asphalt concrete pavement bridge floor, and be to meet that good waterproof performance, stability are good, crack resistance is good, good endurance and layer
Between the good requirement of caking property, typically waterproof layer will be set in deck paving interlayer.Commonly used in concrete bridge deck waterproof
Water-emulsifying type waterproof coatings such as APP modified asphalt materials, neoprene pitch etc., composition structure it is single, with cement concrete bridge deck
The adhesion strength of plate is relatively low, and in the presence of vehicular load, passage, phenomenon of coming to nothing occurs in pave-load layer, so as to cause surface wave
The generation of the diseases such as wave, crack, loose, pit-hole.The bonding of solvent-type waterproofing paint and cement concrete bridge deck plate is preferable, but resistance to
High-temperature behavior is poor.Requirement of the response type water-repellent paint to construction technology is higher, and expensive.
The content of the invention
It is an object of the invention to provide a kind of good waterproof performance, adhesion strength height, heat resistance for cement concrete bridge deck
Good and good economy performance waterproof material.
It is a further object of the present invention to provide a kind of preparation method of cement concrete bridge deck waterproof material.
The purpose of the present invention realized by such technical scheme, a kind of cement concrete bridge deck waterproof material,
It is characterized in that：The waterproof material is to generate carbamate with Pluronic polyols by isocyanates, add and commonly hand over again
Pitch is through tertiary amine catalyst, composite anti-foaming agent and ethyl acetate is composite modified forms；Wherein described isocyanates be prepare it is poly-
The primary raw material of urethane, using toluene di-isocyanate(TDI) TDI or 4,4- methyl diphenylene diisocyanate MDI, it is preferred to use 4,
4- methyl diphenylene diisocyanates MDI；The Pluronic polyols that the present invention uses selects its chlorinated polypropylene glycol of two degrees of functionality
Mixed with its chlorinated polypropylene triol of three-functionality-degree using mass ratio as 4: 1~2: 1, Pluronic polyols mixture mainly provides
Hydroxyl-OH, isocyanates provide isocyanate group-NCO, and the mol ratio control of isocyanate group and hydroxyl is 5: 1~3: 1.
The common heavy traffic paving asphalt needle penetration is 60~100, using No. 70 or No. 90 pitches；Dosage is the aminomethyl of generation
The 75~85% of acid esters；
The catalyst is tertiary amine catalyst, using in stannous octoate, dibutyl tin laurate or triethanolamine one
Kind or several any mixing, dosage are the 0.3~0.6% of isocyanates.
The composite anti-foaming agent uses Ca (OH) 2 and silicone emulsion to be mixed using mass ratio as 1: 1~1: 1.3, dosage
For the 0.3~0.5% of isocyanates.
Solvent considers the feature of environmental protection and dissolubility, and the solvent selects ethyl acetate, dosage for isocyanates 5~
10%.
It is another object of the present invention to what is realized by such technical scheme：One kind, which prepares cement concrete bridge deck and used, prevents
The preparation method of water material, it is characterised in that：
After its chlorinated polypropylene triol of its chlorinated polypropylene glycol of 4: 1~2: 1 two degrees of functionality and three-functionality-degree is mixed
It is that 60~100 common heavy traffic paving asphalts are added in reactors with needle penetration, vacuumizes (make vacuum reach 0~0.05MPa when),
100 DEG C~120 DEG C 1~2h of dehydration, are then cooled to 30 DEG C~50 DEG C；The isocyanates of vacuum dehydration, tertiary amines are urged
Agent, composite anti-foaming agent are added in reactor, are warming up to 65 DEG C~75 DEG C, react 1.5~2.5h；The vinegar that dewater treatment is crossed again
Acetoacetic ester is added in reactor, 40 DEG C~60 DEG C 0.5~1h of insulation；Discharge and lead to nitrogen protection, encapsulation preserves.
By adopting the above-described technical solution, the present invention has the advantage that：
1st, due to containing unsaturated bond in isocyanate structural in cement concrete bridge deck waterproof material of the present invention, because
This has high activity, easily generates polyurethane elastomer with the polyalcohol containing activated hydroxy compound, adds it to common weight
Hand in pitch makes the water resistance of wet-solidifying single-component polyurethane and pitch be improved through composite modified and solvation, and this is anti-
Water material is firmly bonded with cement concrete bridge deck, and high and low temperature resistance is strong, is not trickled, does not slide, is not dripped under high temperature, low temperature
Under do not ftracture, the requirement of the comprehensive function of temperature inversion and long duration load can be subjected to, alleviate the bridge structure caused by infiltration
Destroy, delayed highway bridge service life.
2nd, cement concrete bridge deck of the present invention combines the excellent of solvent-borne type and response type water-repellent paint with waterproof material
Point, cost is greatly reduced than wet-solidifying single-component polyurethane and pitch on the premise of combination property is above standard requirement, is dropped
Inexpensive 25-40%.
3rd, by cement concrete bridge deck waterproof material of the present invention, constructing operation is safe and simple, and speed of application is fast, film forming
Time is short, less demanding to Roadway Construction, can rapid construction.
4th, the preparation method of cement concrete bridge deck waterproof material of the present invention, it is simple to operation, under dewatering state
Isocyanates, Pluronic polyols and ethyl acetate do not decompose, do not aoxidize under vacuum, it is ensured that the stabilization of each component material
Property, make waterproof material solids content height, the material property of preparation good.
