Abstract
The present invention relates to emulsified asphalt modified by adopting water-base epoxy resin. It is characterized by that it utilizes water-base epoxy resin emulsion and solidifying agent to modify the emulsified asphalt, in which the general emulsified asphalt content is 100 portions, water-base epoxy resin emulsion content is 3-15 portions and the solidifying agent content is 20%-25% of water-base epoxy resin emulsion content.
Description
Technical field
The present invention relates to asphalt pavement conserving and keep in repair used modified emulsifying asphalt, be specifically related to a kind of emulsified bitumen that adopts the aqueous epoxy resins modification.
Background technology
Along with rapid development of national economy, the damage of bituminous pavement has been quickened in being on the rise of the increasing substantially of the heavy-duty day by day of traffic loading, the volume of traffic, overloaded vehicle.Therefore strengthen the maintenance of bituminous pavement and the research of repairing technique, and the work-ing life that how to prolong bituminous pavement, good market outlook had.
With the emulsified bitumen is the asphalt road surface local repairing technique of matrix material, have applied range, construction facility, save energy and reduce the cost, reduce plurality of advantages such as polluting, reduce the construction time, but therefore low, the shortcomings such as snappiness is poor, insufficient strength of single emulsified bitumen caking ability have restricted the promotion and application of emulsified bitumen in asphalt pavement conserving and maintenance.
In view of the outstanding advantage of asphalt road surface local repairing technique that with the emulsified bitumen is matrix material, applying of it is imperative, but problem is how to improve the performance of emulsified bitumen, promptly emulsified bitumen is carried out modification, make it have stronger cohesive force, high-temperature stability, superior elastic recovery capability and higher compression, non-deformability or the like, to satisfy the requirement in asphalt pavement maintenance and maintenance.
Summary of the invention
Purpose of the present invention aims to provide a kind of every technical indicator and all is better than common emulsified bitumen, can satisfy the asphalt roads use properties better, prolongs the road modified emulsifying asphalt in work-ing life.
The present invention is a kind of emulsified bitumen that adopts the aqueous epoxy resins modification, adds aqueous epoxy resin emulsion, solidifying agent in emulsified bitumen; The weight percent of said components is: 100 parts of emulsified bitumens, 3～15 parts of aqueous epoxy resin emulsions, solidifying agent are 20%～25% of aqueous epoxy resin emulsion.
Above-mentioned solidifying agent is a kind of fragrant same clan amine of modification, and its main component is aromatic amine, DMP-30 promotor and the phenylcarbinol of modification.
The molecular formula of the aromatic amine of above-mentioned modification is:
The molecular formula of above-mentioned DMP-30 promotor is:
The molecular formula of above-mentioned phenylcarbinol is:
The molecular formula of above-mentioned Resins, epoxy is:
Wherein: n=0.1～0.5 mean polymerisation degree
Oxirane value eq is 0.41～0.55
Epoxy equivalent (weight) is 244～182.
501 reactive thinners:
Emulsifying agent is A: Sodium dodecylbenzene sulfonate B:Tx-10
Protective colloid: PAAS sodium polyacrylate
The explanation of described material
1, emulsified bitumen is mainly by pitch, and emulsifying agent and water are formed.This patent adopts the emulsified bitumen of cationic emulsifier preparation, and it is good that it has adhesion, reaches advantages such as self stable storing performance is good by force with the adaptability of aggregate.
2, aqueous epoxy resin emulsion is a kind of environmental protection low toxicity type water-dispersion emulsion that does not contain volatile organic solvent (VOC); it is mixed and heated to certain high temperature by a certain percentage by Resins, epoxy, emulsifying agent and stirs, and then adds a certain amount of thinner, protective colloid and distilled water therein and stir and make.Its maximum characteristics are dispersed in butyrous Resins, epoxy in the water exactly, make the external phase of system change water mutually into by epoxy solution, and phase reversion (being that W/O becomes O/W) has taken place, and do not contain organic solvent and low toxic and environment-friendly.Aqueous epoxy resin emulsion can cohere with multiple material well, embodied its good performance of sticking, and kept the distinctive performance of Resins, epoxy itself simultaneously again.
Every performance index of aqueous epoxy resin emulsion are as follows:
Oxirane value (eq/100g): 0.41～0.55 epoxy equivalent (weight) (g/eq): 182～244
Viscosity (25 ℃) is (Pas): 0.01～0.025
3, solidifying agent is a kind of fragrant same clan amine of modification, mainly contains following composition: the aromatic amine of modification, promotor, phenylcarbinol softening agent.It mainly acts on is the cohesive material that the aqueous epoxy emulsion curing cross-linked is become tridimensional network, excellent property, and the characteristics of this solidifying agent are that curing cross-linked speed is fast, can shorten construction period greatly.
The key technical indexes contrast before and after the modification:
Illustrate: 1, penetration test is to carry out in 25 ℃ constant temperature waters, the tapering of the standard pin that adopts be 9 ° 31 ', loading 100g, the injection time is 5s.
2, water temperature is heated since 5 ℃ in the softening point test tank.
3, ductility test is to carry out in 25 ℃ constant temperature waters, and draw speed is 50mm/min.
Outstanding advantage of the present invention and unusual effect
1, adopts described solidifying agent, can make the not conglomeration of emulsified bitumen after the modification, keep original liquid.
2, the emulsified bitumen viscosifying power after the modification improves significantly, can fine and original road surface bonding.
3, anti-shearing deformability and Marshall performance index (comprising stability, flow valuve, modulus) are significantly improved than the emulsified bitumen before the modification.
4, simple to operate, do not need heat during construction, can directly mix in concrete or the mortar, form emulsification asphalt cement mortar or emulsified bitumen concrete concrete or emulsified bitulith.Emulsification asphalt cement mortar after the modification or emulsified bitumen concrete concrete or emulsified bitulith early strength height, the length of time lack, and can shorten the time of closing traffic greatly when pavement maintenance.
