Description
Technical field
The present invention relates to a kind of thermosetting epoxy asphalt material and preparation method thereof, be mainly used in the building field.
Background technology
Pitch has good water-fast, moistureproof, non-corrosibility, and its aboundresources, and price is lower, is used to ground surface material and water-proof material etc. for a long time always.But, make it higher to temperature sensitivity because the bituminous relative molecular weight is low and its MWD broad.When elevated temperature, the bituminous strength degradation; Bituminous material becomes fragile when reducing temperature.So largely limit the bituminous widespread use.
Along with the fast development of highway in China construction, among national trunk road network is forming, a large amount of makings of high-grade highway, the construction of long-span bridge beam.Make the use of road bitumen material more and more seem important and general.China belongs to the country in many lakes, many rivers; Longspan Bridge is used widely in road construction; The long-span bridge beam has structure key light weight, transports and set up characteristics such as convenience, short construction period; Though the bridge deck structure of Longspan Bridge have construction simple, from the advantage of heavy and light, it is more and more outstanding that the problem of deck paving also seems.Especially bridge floor is easy to produce early damage.Because the bituminous concrete resistance to elevated temperatures is poor, and steelwork belongs to the good conductor of heat, and during summer high temperature, pass easily at the interface between carload and pyritous coupling lower steel plate and bituminous concrete; Simultaneously; Because bituminous concrete has certain gap, rainwater is prone to see through oil mat and oozes to surface of steel plate, under the acting in conjunction of water and air; The water-proof tack coat of surface of steel plate subjects to destroy, and then reduces the interface binding intensity between steel plate and the bituminous concrete.Make will occur when steel box girder bridge runs into summer high temperature in various degree passing, hold together diseases such as bag and rut.Need asphalt that stronger deformability is arranged during winter.Therefore, the pitch that the steel bridge deck paving is used not only needs the excellent high-temperature rutting resistance, low temperature cracking resistance ability, and need good antifatigue deformability.Obviously.Plain asphalt can not satisfy above-mentioned requirements, has only pitch is carried out modification, could satisfy above-mentioned requirements.
One is meant polymer modified asphalt modifying asphalt, and the type of polymer that is used for modification is a lot, and one is commonly used has tree elastomer, styrene-butadiene rubber(SBR), styrene butadiene block copolymer, Vilaterm, ethene one acetate ethylene copolymer and epoxy resin etc.Wherein epoxy modified asphalt is usually used in the modified asphalt material that motorway and bridge are used.In CN1546571, provided the epoxy bitumen material that comprises that a kind of motorway and bridge use with the polyisobutylene butanedioic anhydride modification.In CN1952012, provided senior fatty carbon chain that a kind of use contains low-pole and strong polar mannich base or epoxy resin and the dedicated compatibilizer modification of the epoxy bitumen material of the compound of polyvalent alcohol composition thermosetting epoxy asphalt material, it must not carry out chemical modification to pitch; Need not limit the bituminous kind yet; Only need in pitch, add dedicated compatibilizer, cooperate conventional epoxy resin and solidifying agent just can form thermosetting epoxy asphalt material.In CN101003688, provided relate to a kind of with pitch, solidifying agent, promotor, the high performance pavement material of epoxy asphalt that skimmer is formed.It has good solidity to corrosion, water tolerance, weathering resistance, resistance to fatigue, high temperature creep resistant and low temperature resistance to brittle fracture.In CN101020601, provided a kind of poured epoxytar laying of roadway material with modification alkylphenol, glycidyl ether modification.It is a kind ofly have that construction temperature is low, good fluidity, the poured epoxytar concrete material easily of constructing.USP6399680 has provided with the sulfuric acid of the 0.02-3% of modifying asphalt total amount, phosphoric acid, Glacial acetic acid min. 99.5 or nitric acid and has done promotor, contains the modifying asphalt that the multipolymer of epoxy group(ing) of the 0.2-15% of modifying asphalt total amount is processed; Provided among the USP4162998 with polyamines and epoxy resin modification bituminous method; USP5576363 has provided the method for preparing the two-pack modified asphalt material with modifications such as multipolymer that contains epoxide group and carboxylic acids; USP4360608 has provided with pitch, the epoxy bitumen material that epoxy resin and polyether glycol expanding material are formed, and as road surfacing material, it has thermal deformation resistant ability and trickling property preferably.Provided the modifying asphalt that the modifying asphalt that contains the mineral acid group and linearity or branched polymers prepare among the USP5095055, the road surface of laying this kind material has the visco-elasticity of the property improved, and softening temperature raises, the storage-stable property improvement.Provided the polymer modified asphalt material that total amount 0.1-5% contains epoxide group among the USP5306750; The polymkeric substance that contains epoxide group forms external phase in pitch; Obtain having anti-rut thus, low temperature cracking resistance, the thermosetting modification pitch of anti-flexible fracture and anti-wet damage ability.In the thermoplastic polymer modifying asphalt; Because epoxy resin and bituminous consistency are poor; Do not form netted crosslinking structure by the pitch in the thermoplastic polymer modifying asphalt, epoxy resin and polymkeric substance; Of long duration from asphalt component, separate out easily, thereby cause the downgrade of modifying asphalt.In the thermosetting epoxy resin modifying asphalt; Be that a small amount of epoxy resin is added in the pitch; Warp and solidifying agent generation curing reaction, the irreversible solidifying agent of formation cross-linked network, its curing reaction makes pitch from the thermoplasticity converted into thermoset; Therefore thermosetting epoxy asphalt have than plain asphalt excellent physics, the mechanical property of Duoing, like HS, good anti-fatigue performance, favorable durability and ageing resistance etc.
