As a railroad track, a roadbed made of ballast such as crushed stone or gravel is provided on the roadbed, and sleepers are placed on the roadbed to fasten the rails. The ballast made of this ballast has the role of distributing the train load transmitted from the sleepers and transmitting it to the lower roadbed, and absorbing the vibration when the train passes.

ある。However, in a ballast using a ballast, the ballast moves or collapses due to vibration caused by passing trains. As a result, there is a problem in that the resistance force to the train lateral pressure of the sleepers decreases and it becomes a dangerous state. In addition, when a train runs at high speed, the surface layer of the roadbed floats up by the wind pressure of the train, collides with a train passing directly above, and the ballast may scatter, which is dangerous.

It is known that the ballast is fixed by spraying the mixture etc. on the surface of the roadbed, but since these water-based resins cure slowly, they flow down deep inside the roadbed before curing, and the ballast collapses when walking on the roadbed. Will end up. In addition, if there is rainfall before hardening, it will be washed away by rainwater and will flow into the fields and rivers, which poses the risk of secondary pollution.

The pot life from the mixing of the liquids to the use is restricted. Especially, if the curing time is shortened, the pot life is shortened and it is necessary to carry out the construction in a short time.

The urethane elastomer disclosed in this publication has a curing rate. It is slow and takes a long time of 10 to 24 hours to develop a target strength. Therefore, an amine catalyst and a metal catalyst are used together in order to accelerate the curing.

However, there is a defect that the cured product foams or becomes brittle.

ことから取扱い性、作業性においても優れている。In the anti-scattering material composition, it is considered that the amine polyol (A) acts as a reaction accelerating catalyst when the isocyanate group reacts with moisture in the air or moisture in the contact substance. Generally, as the reaction promoting catalyst, a metal catalyst is used in addition to a tertiary amine. However, when these catalysts are blended with the urethane prepolymer to make it one-component, the reaction of the isocyanate group with the nurate formation reaction or However, three-dimensional structuring such as burette reaction occurs, which causes thickening or gelation, which makes it difficult to store for a long time. On the other hand, in the present invention, the amine polyol (A) contains an aliphatic amine in the molecule and has a reaction catalytic activity, but has a three-dimensional structure such as a nurate-forming reaction or a buret-forming reaction of an isocyanate group. Since it does not undergo chemical conversion, it has excellent storage stability. Moreover, since the amine polyol (A) has an aliphatic group having 2 to 24 carbon atoms, it has good compatibility with other polyol components and polyisocyanate, and excellent adhesive strength and curing promoting action can be obtained. . Further, since it is a one-liquid type, it is excellent in handleability and workability.
