Advantage of the present invention is: the passenger dedicated railway line sleeper has working resistance greater than 10 with rubber bearing owing in the product rerum natura down
8The requirement of Ω, so just can not use as the strengthening agent carbon black in the sizing material, this class prescription all adopted white carbon black to carry out the requirement of additional properties except black-reinforced originally more.But Line for Passenger Transportation is higher to the requirement of the ageing-resistant of product and sound stiffness ratio with rubber bearing, thus with white carbon black as a supplement strengthening agent do not satisfy the requirement of product.The present invention has adopted type material nano kaoline and nano-calcium carbonate.
Nano kaoline is because particle size is little, specific surface area is big, very strong surface effects, dimensional effect and macro quanta tunnel effect are arranged.Nanoparticle and polymkeric substance are compound, not only can obviously improve intensity, rigidity and the toughness of polymkeric substance, can also increase the functional performances such as barrier, thermotolerance and resistance to deterioration of polymkeric substance.
The nano kaoline crystal is laminar.Nano kaoline/rubber composite has good thermal stability, be on the one hand because the potter's clay lamella is arranged in parallel in matrix material in the form of sheets, rubber molecule interts between the potter's clay lamella, the part macromole directly is connected with lamella, wherein have strong interaction, clay layer is equivalent to cross-linking set; The potter's clay lamella has the good barrier properties energy on the other hand, and the decomposition of rubber macromolecule therebetween is suppressed, thereby has improved the thermal stability of matrix material.According to the data introduction, the initial weightless temperature of nano kaoline/rubber composite has improved 20～45 ℃ than white carbon black/rubber composite, stops degradation temperature and has improved 50～90 ℃, and this explanation nano kaoline more can improve the thermostability of rubber than white carbon black.This conclusion has also obtained confirmation in our rubber bearing test recipe.
