Description
Technical Field
The invention relates to the field of track slab insulating materials, in particular to a prepolymer composition and an insulating material.
Background
The isolation material is sprayed on the track slab at the position which can be contacted with cast-in-place concrete to form a material which is attached to the track slab and has a certain thickness. The main functions are as follows: (1) the cast-in-place concrete and the precast slabs are isolated, so that the track slab can be conveniently separated from the cast-in-place structure during hoisting when the track slab needs to be replaced after the track traffic is operated; (2) the limiting part of the track plate plays a certain role in buffering, so that the problem of stress concentration of the track plate at the limiting structure is avoided; (3) the isolation material also has good waterproof and insulating properties, is favorable for preventing the surface of the track slab from seeping water and protecting stray current, and improves the durability of the track slab.
However, the cracking of the track slab is one of the important technical problems in the construction and operation of the high-speed railway, and once the crack is formed, the crack causes great harm, which reduces the durability of the track, reduces the insulating performance of the track, weakens the bearing capacity of the track, and may also cause adverse effects on the use safety of the track. Because the high-performance concrete has large cement consumption and high hydration heat, the internal temperature of the concrete rises and the concrete expands; the concrete external temperature will decrease due to the non-adiabatic state of the element. When the tensile stress produced by the shrinkage of the concrete exceeds the tensile strength of the concrete, the concrete will crack.
At present, the rail plate cracks caused by temperature are not effectively solved, a later-stage repairing technology is mostly adopted, a repairing material is usually high-permeability organic resin, the material can effectively delay reinforcing steel bar corrosion and concrete carbonization caused by the cracks, and the problems cannot be fundamentally solved.

In a more preferred embodiment of the present invention, the aromatic diisocyanate having 8-26 carbon atoms is more preferred from the viewpoint of prepolymer reaction conditions and product characteristics; specifically, MDI or TDI is preferred.
In the study, by comparing the amounts of prepolymer I and prepolymer II, it was found that when the amount of prepolymer I was adjusted, the high temperature resistance and low temperature resistance were substantially unchanged, while the water soak resistance and water impermeability were significantly reduced, which was caused by the decrease in the crosslink density and/or the increase in the number of defects in the polymer chain due to the presence of prepolymer I alone. The comparison shows that the prepolymer I obtained by the reaction of the raw materials in the prepolymer I and the polyisocyanate has enough time and complete reaction, and then the prepolymer I and the prepolymer II react, so that the ordered regular arrangement of macromolecules is easily formed, and the water immersion resistance and water impermeability of the prepolymer I and the prepolymer II can be improved together.
When the content of the prepolymer II relative to the prepolymer I is very high and exceeds the preferable range (33-38): (18 to 23), the viscosity may be high, and cracks may be caused by self-thermal degradation after a test at a high temperature, and the thermal degradation phenomenon may be accelerated by the powder filler. Too small a content can also result in unstable water resistance of the isolating material; therefore, within a reasonable range, after cross-linking polymerization, the hard chain segment and the soft chain segment are most easily arranged in order, in fact, the difficulty that the stable and ordered arrangement of the chain segments can be controlled only by reducing the viscosity of the system under the premise of ensuring a certain solid content is generally solved in that the adjustment and control are needed under the conditions of a large amount of polyhydric alcohol and less isocyanate, but the adjustment and control of the proportion of the polyhydric alcohol and the isocyanate in the prior art obviously influence the high-temperature and low-temperature performance, and experiments prove that the lower viscosity can be ensured and the larger interaction and the better microphase separation degree among the macromolecules of the prepolymer can be promoted after the compound of the general formula (1) is considered.

4. Water impermeability: the prepared isolation material in each example is prepared into a sample with the thickness of 2mm, and after the sample is solidified and is tested for 28 days according to the test method in GB328.10-2007 test method for waterproof coiled material for building asphalt and polymer coiled material impermeability, the result is 0.3MPa and 100d, and the waterproof performance is realized.
The results are shown in Table 1, and the results are rated using +, ++, +++ with more + indicating better results.
