Abstract
The invention provides a shock absorption backing plate for a rail and a preparation method thereof. The shock absorption backing plate for the rail is mainly prepared from the following raw materials in parts by weight: 40-60 parts of TPU (Thermoplastic Polyurethane) particle, 10-29 parts of silicone rubber, 20-40 parts of butadiene styrene rubber, 20-30 parts of white carbon black, 1-5 parts of a coupling agent, 2-3 parts of a cross-linking agent and 1-3 parts of an initiator. According to the shock absorption backing plate and the preparation method provided by the invention, by using the synergistic effect of phenolic resin, the silicone rubber and the butadiene styrene rubber according to the weight parts, the obtained shock absorption backing plate for the rail has the advantages of good mechanical properties and shock absorption and buffering effects, excellent oil resistance, weather resistance and insulating performance.
Description
Technical field
The present invention relates to a kind of rail shock-absorption backing plate and preparation method thereof.
Background technology
China is carrying out large-scale Line for Passenger Transportation and high speed railway construction, to build up more than 10,000 kilometer of Line for Passenger Transportation to the year two thousand twenty, form the Line for Passenger Transportation skeleton of " four horizontal four vertical ", build up more than 2000 kilometer of the high-speed railway in ring Bohai Sea Hai Quan, the Yangtze River Delta and area, Pearl River Delta.Along with improving constantly that people require train running speed, how solving the vibrations and the impact that in Vehicle Driving Cycle process, cause becomes a very crucial problem.
In order to reduce vibrations, to reduce noise, Novel fastener system has designed resilient sleeper-bearing under iron chair, is the key elastic element in high-speed railway fastener system, and rigidity, fatigue property and over-all properties to whole fastener system play a decisive role.
Silicon rubber molecular backbone chain alternately forms siloxane bond by Siliciumatom and Sauerstoffatom, siloxane bond bond energy is more much bigger in conjunction with bond energy than ordinary rubber carbon-to-carbon, siloxane bond helically configuration, Chain Flexibility large (larger than C-C or silicon-carbon bond), these constitutional featuress make its cross-linked rubber softness and are rich in excellent elasticity.In the time of temperature change, the reactive force between molecule changes very little, so its various performances, especially Flexible change is very little, and the Flexible change of ordinary rubber is greatly because temperature reduces the cause that rear Intermolecular Forces greatly strengthens.In addition, silicon rubber also has excellent oil resistant, high-low temperature resistant, ageing-resistant and insulating property.The shortcoming of silicon rubber is that mechanical property is poor, and especially tensile strength is low, and therefore, for a long time, people do not select the material of main part of silicon rubber as resilient sleeper-bearing.
CN 102618038 A disclose a kind of railroad track damping resilient sleeper-bearing and preparation method thereof.Resilient sleeper-bearing of the present invention is made up of by mass parts following starting material: 100 parts, silicon rubber, 25～70 parts of strengthening agents, 1～6 part of constitution controller, 0.5～3 part of vulcanizing agent.This invention selects the silicon rubber with excellent resilience as material of main part, by complete processings such as mixing, sulfidization moldings, prepared a kind of rubber bearing with excellent fatigue property and lower static rigidity, this invention possesses following performance: 1. snappiness, low static rigidity.2. the fatigue property of excellence (by " the provisional technical qualification of passenger special railway line fastener system " regulation, having passed through 3,000,000 fatigue tests).3. possess good oil-proofness, Weather-resistant and insulating property, played good damping, shock absorption, improved bullet train riding comfort and security.But the main rubber adopting due to this invention is silicon rubber, mechanical property is poor.
