Description
Technical fieldThe present invention relates to a kind of Cement Concrete bridge floor with bituminous epoxy sticking material and preparation method thereof.
Background technologyThrough construction practice and experimental study in recent years; Understanding to bridge deck water-proof tack coat is goed deep into gradually; Construction quality also is significantly improved, but some problems below also existing: the one, the water-proof material quality is very different, and the advanced deficiency of industry standard makes material screen difficulty; Mechanical property is generally not enough, is difficult to tackle the requirement of harsh road conditions; The 2nd, the material workability is not good, causes construction technology without ready patterns to follow, is difficult to guarantee construction quality; The 3rd, on-the-spot detect (like shearing resistance, bonding strength) have to be strengthened so that effective control engineering quality.This shows that pavement performance is good, the novel material that workability is excellent is the key point that solves the bridge deck water-proof tack coat quality problems.
When on the Cement Concrete bridge deck paving of asphalt being set, oil mat should have with concrete slab bonding firmly, waterproof infiltrates, antiskid is wear-resisting, the superperformance of low temperature cracking resistance, the anti-rut of high temperature, antistripping.
The cement concrete bridge deck asphalt pavement should be made up of adhesion coating, waterproof layer and oil mat, and bridge deck water-proof tack coat promptly is the address that adhesion coating and waterproof layer are united two into one.How to carry out this one deck, along with improving constantly of road quality classification, its requirement is also increasingly high.
Summary of the inventionBut the present invention is according to the objective requirement of bridge deck water-proof adhesive linkage to mechanical characteristic, endurance quality application property and engineering economics property; In conjunction with transportation industry and relevant national standards; Each related test subject of physical and chemical standards, use properties and endurance quality of water-proof bond material has been proposed; Test conditions and index request, and the foundation and the reasonableness of associated viscera analyzed.
The technical scheme of the object of the invention is that pitch, epoxy resin, dispersion agent, epoxy curing agent, the agent of polymer toughness combine.Pitch is at least a in petroleum pitch, oxidized bitumen, coal-tar pitch or the lake pitch; The agent of polymer toughness comprises at least a in styrene-butadiene-styrene block copolymer, Vilaterm, Vestolen PP 7052, nylon, SE, ethylene-methyl acrylate copolymer, ethylene-propylene rubber(EPR), ethyl acetic acid-vinyl acetate random copolymers, tree elastomer, polyhutadiene, TR 301, butyl rubber, SBR styrene butadiene rubbers, neoprene latex and the waste tire rubber powder; Epoxy resin cure comprises at least a in trolamine, 1,6 hexanediamine, Dyhard RU 100, A40 epoxy hardener, 590 solidifying agent, the Amino Terminated polyether(ATPE); Dispersion agent comprises at least a in TKK 021, Natvosol, gelatin, tsp, the industrial sodium hexametaphosphate.
The Cement Concrete bridge floor stirred pitch, epoxy resin and macromolecule modifier 4 hours with the preparation method of bituminous epoxy sticking material on high speed dispersor, temperature is controlled at 40 ~ 60 ℃; Cool the temperature to 20 ~ 25 ℃, slowly add epoxy curing agent and dispersion agent and stir after 2 hours, promptly get Cement Concrete bridge floor of the present invention and use the bituminous epoxy sticking material.
Cement Concrete bridge floor of the present invention is following with bituminous epoxy sticking material performance:
Solid content >=43%; Cohesiveness >=0.4MPa;
High temperature shearing resistance (60 ℃) >=0.16MPa; Watertightness: 30min does not seep water under the 0.3MPa pressure;
Snappiness: (20 ± 2) ℃, flawless, fracture; Frost resistance :-20 ℃, do not ftracture for 20 times;
Anti-pressing against brokenly and infiltration: after exposing rolling test (0.7MPa, 100 times), do not seep water under the 0.3MPa hydraulic pressure
Construction technology:
1. the cleaning of bridge floor and flushing
Remove the cement concrete bridge deck sand-cement slurry by regulation with ball blast technology or milling technology, and the water flushing, guarantee cleaning surfaces, the secondary pollution of visible dust, greasy dirt and other dirt must not be arranged.
2. spray the Cement Concrete bridge floor and use the bituminous epoxy sticking material
Behind the moisture content dryness in the sun of bridge floor flushing, promptly available intelligent distribution vehicle sprays NKY water-proof binding layer material.Vertically be connected and spilt the cloth 10cm of overlapping.It is 0.8～1.0kg/m2 that the Cement Concrete bridge floor uses bituminous epoxy sticking material consumption.On bridge floor, place square plate during sprinkling, spill the cloth amount with measurement; Square plate is taken the down blank bridge floor using artificial benefit in back away and is spilt water-proof material.
3. water-proof bond material carries out natural curing after spilling cloth immediately, mustn't the pedestrian or vehicle pass through because sticking wheel and paver crawler belt after the drying of materials, so do not need the spreading rubble.
4. after the water-proof tack coat drying, should carry out bituminous mixture laying as early as possible.
EmbodimentTake out specific embodiment of the present invention below:
The example 1, petroleum pitch, epoxy resin and macromolecule modifier were stirred on high speed dispersor 4 hours, its ratio is a pitch: epoxy resin: (styrene-butadiene-styrene block copolymer+tree elastomer+polyhutadiene)=60:30:10; Temperature is controlled at 40 ~ 60 ℃; Cool the temperature to 20 ~ 25 ℃, slowly add epoxy curing agent and dispersion agent and stir after 2 hours, promptly get Cement Concrete bridge floor of the present invention and use the bituminous epoxy sticking material, the barrelling sealing is preserved.
Example 2, with example 1, different is, macromolecule modifier be (styrene-butadiene-styrene block copolymer+butyl rubber+SBR styrene butadiene rubbers), fully stirring promptly gets product.
