Description
Technical field
The present invention relates to a kind of novel high speed highway and epoxy asphalt material for road-bridge and preparation method thereof.
Background technology
The staple of petroleum pitch is the mixture of fat hydrocarbon and arene, and its SP is about 8.66, and the SP of epoxy resin is 10.36, therefore is difficult to compatible.For effective preparation bituminous epoxy starting material, scientists has adopted following technology: cosolvent method, modifying asphalt method, use special epoxy resin method and use modified firming agent method etc.Like U.S.Pat.3, adopt in 012,487 Stockholm tar as epoxy resin and bituminous cosolvent;, successfully prepared the bituminous epoxy adhesives, and be applied in concrete surface and the roadbed as solidifying agent with diethylenetriamine, Tetra hydro Phthalic anhydride etc.; Obtain antiskid coating hard, coarse, anti-solvent, obviously, Stockholm tar as the solvent final residue in system; Performance to material produces bigger influence, and the product that obtains is hard, crisp; U.S.Pat.4 has synthesized two kinds of active cosolvent in 360,608, and simultaneously to discussing as the situation of cosolvent with phenols (like NP etc.), when finding to adopt 40 parts of NPs as the cosolvent of system, and the product homogeneous phase, but flexural strength is lower; U.S.Pa t.:4,139,511 are adopted as a small amount of maleic anhydride (5%, 10%) or maleic anhydride ester carries out modification to pitch under the pyritous situation; Pitch and the epoxy resin of finding gained have good consistency, and employing amine value is 315 a polymeric amide during as solidifying agent, and the ultimate tensile strength of the material that obtains is 2.1MPa; Unit elongation is 60%, yet it requires at the high temperature more than 200 ℃ the bituminous modification; And long reaction time, energy consumption is big, and unit elongation is with respect to the bituminous epoxy of the Chemco System of present engineering use; Its unit elongation is still very little, is difficult to satisfy the requirement of some paving steel bridge decks; CN200710019324.X adopts modified tung oil acid anhydrides and modified castor oil acid to mix as solidifying agent, and the maximum elongation at break of the bituminous epoxy of preparation is 441%, and tensile strength is 5.62MPa, but its its domestic application also is not very wide at present.
Yet, the still main dependence on import of present domestic bituminous epoxy, its price very expensive 10-20 of plain asphalt (approximately be doubly), and domestic research and development to bituminous epoxy also only are at the early-stage.
Summary of the invention
The object of the invention is in order to overcome problem and the defective that prior art exists; A kind of motorway and epoxy asphalt material for road-bridge and preparation method thereof are provided; The prepared bituminous epoxy of the present invention has good tensile strength and high-elongation, and technology is simple, and is with short production cycle; The part that can fill up domestic bituminous epoxy technical field is blank, and can be easy to satisfy the demand of domestic extensive construction.
Thinking of the present invention is based on the judgement principle of the consistency between the macromolecular material, and molecular structure is designed, and prepares the epoxy bitumen material that can be used for the road and bridge aspect of HS, high-elongation and ultra fatigue performance.
Technical scheme of the present invention is:
A kind of motorway and epoxy asphalt material for road-bridge is characterized in that: be made up of A, B two portions, and the A part is 2.0-3.5 with B mass ratio partly: 1;
Described A part is made up of following each component; Each components in mass portion meter: 300 parts of pitches, tung oil-modified epoxy resin 90-250 part, aliphatic dicarboxylic acid or gather aliphatics dicarboxylic acid anhydride 30-90 part; Epoxy resin cure promotor 0-1 part, unsaturated acid anhydride 40-70 part;
Described B partly is that epoxy resin is or/and contain the glycidyl ether of epoxy group(ing).
The described glycidyl ether that contains epoxy group(ing) is that butanediol diglycidyl ether, pentanediol diglycidylether are or/and hexanediol diglycidyl ether.
Described pitch is petroleum pitch, oxidized bitumen, coal-tar pitch or lake pitch.
Described epoxy resin is a kind of in the epoxy resin of bisphenol A-type, bisphenol S type, Bisphenol F type or mixture more than two kinds.
Described unsaturated acid anhydride is a kind of in methyl tetrahydro phthalic anhydride, maleic anhydride, the tung oil acid anhydride or mixture more than two kinds.
Described aliphatic dicarboxylic acid is a kind of in oxalic acid, propanedioic acid, Succinic Acid, pentanedioic acid, hexanodioic acid, pimelic acid, nonane diacid, sebacic acid, dodecanedioic acid, the tetradecane diacid or or mixture more than two kinds.
Through adjustment A, the two-part ratio of B, can obtain the epoxy bitumen material of different purposes.
The epoxy bitumen material preparation method that motorway of the present invention and bridge are used has following two kinds:
Method one:, with aliphatic dicarboxylic acid or gather in the pitch that aliphatics dicarboxylic acid anhydride, unsaturated acid anhydride and epoxy resin cure promotor joins 90-160 ℃, stir until the system viscosity homogeneous by above-mentioned each material consumption prescription; Add tung oil-modified epoxy resin then; Stirring prepares the A component until the system viscosity homogeneous, and the epoxy resin that adds the B part again is or/and contain the glycidyl ether of epoxy group(ing); Mix, make the epoxy bitumen material that motorway and bridge are used.The epoxy bitumen material that motorway that the present invention makes and bridge are used is directly as road surface adhesive linkage material; Or admixing building stones again, insulation 5hr carries out road pavement again.
Method two: by above-mentioned each material consumption prescription, (1) or/and butanediol diglycidyl ether, tung oil-modified epoxy resin are heated to 80 ℃, mixes subsequent use epoxy resin; (2), stir, until the system viscosity homogeneous with aliphatic dicarboxylic acid or gather aliphatics dicarboxylic acid anhydride, unsaturated acid anhydride and epoxy resin cure promotor adds in 140 ℃ the pitch and disperses; (3) with (1), the mixture that makes of (2) step mixes and makes the epoxy bitumen material that motorway and bridge are used.The epoxy bitumen material that motorway that the present invention makes and bridge are used is directly as road surface adhesive linkage material; Or admixing building stones again, insulation 5hr carries out road pavement again.
Tung oil-modified epoxy resin of the present invention is Hubei University's Materials Academy production.
Epoxy bitumen material of the present invention solidifies the back system and is homogeneous phase, introduces a large amount of flexible chains in the system, and whole epoxy systems toughness and plasticity are strengthened, and be different from the rubber toughened theory of Traditional use: promptly rubber is island shape structure distribution in system; The cured product that obtains has HS, high-elongation and ultra fatigue performance, and its performance adjustability is very strong; Technology is simple, and is with short production cycle.
The present invention can be used for motorway and bridge etc. and requires high higher occasion, also can be used for arterial street, motorbus bus stop and airport pavement, in addition, also can be used for the pavement patching such as the cementation of fissures etc.
