Description
Technical field
The present invention relates to a kind of chemical materials, and preparation method thereof with its using method, especially a kind of unsaturated resin composition, and preparation method thereof with its using method.
Background technology
Railway particularly the development of high-speed railway be solve that the national economy high speed development sharply increases logistics, the stream of people and energy shortage between contradiction, reduce the effective way of transportation cost, but along with train running speed improves constantly, the ballast aggregate efflorescence of ballasted track and the speed of railway roadbed accumulated deformation are accelerated thereupon, must satisfy the requirement of high-speed railway to circuit high ride, high stability by track structure reinforcement and frequent maintenance work.Compare with ballasted track, ballastless track has the significantly outstanding advantage of minimizing of trajectory stability, rigidity homogeneity and good endurance, ride comfort height, maintenance load.Therefore, from the early sixties in last century, the countries in the world railway is carried out with monoblock type in succession or is solidified the systematic study that railway roadbed substitutes all kinds of ballastless track structures of bulk solid ballast aggregate, and some countries have popularized ballastless track in an all-round way and used as the main track structure pattern of high-speed railway.
On high-speed railway, use ballastless track, with Japan, Germany is the most extensive.Wherein Japanese the Shinkansen plate-type slag-free orbit pattern be up to now working time the longest, lay the longest plate-type slag-free orbit of mileage.China's ballastless track construction last century the nineties begin design and build with test, it is the dog river grand bridge (straight line) of 741m and two what grand bridge (curve) examination bed board formula track that length is 740m that Qinhuangdao Shenyang Special Passenger Line in 1999 is selected length, in the June, 2003 and the end of the year 2003 are again in the examination shop of having carried out slab track in No. 2 tunnels of cobble mouth, bosom, Chongqing, finish the construction of the line 13.6km ballastless track comprehensive test section that changes then the end of the year 2006, and carried out the operation that is open to traffic of speed per hour 250km, open new page on the railway construction in China history.
Plate-type slag-free orbit is made up of ready-formed track plate, concrete bed and marginal CA filled with mortar layer, establishes convex blocking platform between 2 blocks of track plates.For slab track, the concrete convex blocking platform that the track plate is played position-limiting action directly bears longitudinal force and the transverse force that is delivered to sub rail foundation by rail, comprising: the longitudinal force that the interphase interaction of beam rail produces, the track plate contractility that temperature variation causes, horizontal drag, starting and the damping force of track, the horizontal force between wheel track etc.Except above-mentioned mechanical effect, the packing material around the convex blocking platform, also need bear expose to the sun and rain, stress that environment such as ultraviolet ray produces is with aging, easier destruction.Because the complicacy of convex blocking platform Working environment and to the diversity of performance requriements, require packing material under condition of different temperatures, all cement structures spare to be had good cohesiveness, with transmitted load, and have suitable elasticity and do not produce big deformation and cracking to bear the external force effect.In addition, under all temps condition, must consider that also it uses manufacturability, but suitable working viscosity and usage period and curing speed, more than every performance requriements do not obtain in the prior art satisfying well.Packing material around the convex blocking platform, what Japan adopted in early days is the CA mortar, through having disrepair phenomenon after the operation after a while, use the synthetic resins material substitution CA mortar of intensity height, elasticity and good endurance afterwards instead, used synthetic resins mainly is urethane resin.
Though it is urethane resin has favorable elasticity and splitting resistance as the convex blocking platform potting resin, not so good to the bond effect of cement.The more scabrous processing performance that is to use operation will be reacted generation CO because urethane resin, is met water to water vapor sensitive
2, a large amount of bubbles appear easily, influence the compactness and the homogeneity of potting resin.In the open air under the execution conditions, can not use heating cure shelter isocyanate and can only be in ambient cure, the cement product is difficult to drying, steam is difficult to get rid of, and brings very big difficulty to construction.In order to reduce the generation of bubble, often promotor is quickened gel and the solidified way realizes by adding, but the promotor add-on also is difficult to hold, and it is bigger that its consumption is influenced by temperature, add-on very little, then set time is long, foaming is serious, and add-on has little time to use with regard to gel at most.
Except that urethane resin, also can adopt the packing material of Resins, epoxy as the plate-type slag-free orbit convex blocking platform.Compare with urethane resin, it uses manufacturability and all more excellent to the cohesive force of cement, but the ordinary epoxy resin cured article is more crisp hard, Young's modulus is too high, does not meet retaining platform packing material and has certain elastic requirement, though can produce certain elasticity by adding softening agent or toughner, but as time passes, softening agent or toughner may be moved to the surface owing to itself do not participate in curing reaction, and resin becomes fragility again.
In addition, contain the two keys of a large amount of phenyl ring in common polyurethane resin and the ordinary epoxy resin molecular structure, can cause chain rupture under long-term uviolizing, cause resin-oatmeal to melt and split, bring hidden danger for railway operation steady in a long-term, maintenance cost increases.
