Description
Technical field
The invention belongs to road engineering asphalt material technical field, it particularly relates to arrive a kind of based on UV curing actions
Selfreparing pitch and preparation method thereof.
Background technology
" interface " that bituminous paving is directly related as road with driving, has special heavy in whole pavement structure
The meaning wanted.During the long-term use of bituminous paving, the test of various complex environments is experienced at its structure, some are small
Cracking and local damage can be produced inevitably, such as can not in time control these micro-damages, and these micro-cracks will be in outside
Extended in the presence of load and ftractureed, and then the service life of pavement structure, structure heavy then that whole road can be destroyed can be influenceed.Institute
How timely and effectively to repair the crackle that occurs in road surface and main asking of damaging that the person that becomes road work is concerned about
Topic.Pitch possesses certain self-healing capability in itself, but closely related with residing temperature, the time repaired, in practical application
Seldom there is long-time hot stage for its generation self-healing.Therefore, it is necessary to seek a kind of new technology, to inside asphalt pavement
The crackle of appearance and damage can in time be perceived and actively repaired, and its self-healing capability be lifted, to extend road surface service life.
Self-repairing microcapsule is the selfreparing means that a class is carried out with material supply mode.Cyst wall is taken to coat the hand of capsule-core
Microcapsules, when material produces micro-crack, are produced stimulation, cyst wall rupture to discharge core materials by section, and core materials run into point
The catalyst in system is dispersed in, goes out to react in micro-crack, improved substrate performance, delay material damage, extension material lifetime.
There is applicability wide, mature preparation process due to microcapsules selfreparing, small influenceed on substrate performance, the concern being subject to
Research is the most extensive.
Ultraviolet light (UV) curing technology refers under the ultraviolet light of appropriate wavelength and light intensity, in light-cured resin system
Light trigger absorb radiation energy after form the material containing unsaturated double-bond or epoxide group in active group, and then initiation system
Between chemical reaction (mainly each type of polymerization), formed containing crosslinking space network high molecular polymer.UV consolidates
Change material to be typically made up of prepolymer, diluent, light trigger and other auxiliary agents.Current photocuring technology is obtained in the world
Develop rapidly, be widely used in coating, ink, adhesive, printing board material, electronics industry, microfabrication and rapid shaping etc. and permitted
It is multi-field.Compared with traditional heat cure, ultraviolet light polymerization has various advantages：Save energy；Fast (the 0.1- of curing rate
10s), temperature is low, production efficiency is high；Solvent-free or comprise only a small amount of solvent, volatile quantity is small, safe of low pollution；Can one-component.
At present, the research for UV-curing technology being applied into pitch is also relatively fewer.
The content of the invention
In order to solve the above technical problems, the invention provides one kind improve asphalt performance, increase the service life based on UV
Selfreparing pitch of curing action and preparation method thereof.
A kind of selfreparing pitch based on UV curing actions of the present invention, the selfreparing pitch includes being dripped by oil
Blue or green and self-repairing microcapsule, the two mass ratio is 100：0.1-10；The asphalt is《Asphalt highway construction technology
Specification》One kind in matrix 70# asphalt, 90# asphalt or modified oil pitch specified in JTG F40-2004；Institute
Self-repairing microcapsule is stated to be made up of cyst wall and capsule-core, and external skin photomask agent；The cyst material is C5 Petropols, capsule
Core material is UV solidified resin systems, and the two mass ratio is (1:3)-(3:1).
