Mixed passenger and freight railway rubber adapter plate

Abstract

The invention provides a mixed passenger and freight railway rubber adapter plate. The rubber adapter plate adopts a composite rubber material, and the composite rubber material adopts the following components in parts by weight as raw materials: raw materials in a primary rubber mixing process comprising butadiene-styrene rubber, zinc oxide, stearic acid, a first anti-aging agent, a second anti-aging agent and a silane coupling agent; raw materials in a secondary rubber mixing process comprising high abrasion furnace black, a bonding agent and nano-clay; raw materials in a third rubber mixingprocess comprising a first accelerant, a second accelerant and sulfur. The rubber adapter plate disclosed by the invention has the beneficial effects that the butadiene-styrene rubber is taken as a base stock, a reinforcing agent, a vulcanizing agent, the bonding agent and other assistants are added to cooperate with rubber mixing, and the formula is reasonable, so that vibration reduction performance of the composite rubber material is greatly improved, and the composite rubber material is simple in preparation process and low in cost input, and is improved on aspects such as wear resistanceand aging resistance of the rubber material.

Description

technical field [0001] The invention relates to a technology for laying train tracks, in particular to a rubber backing plate for passenger and cargo collinear railways. Background technique [0002] The key point of modern railway operation is how to solve the impact of vibration and noise on the environment and residents' life in rail transit. Vibration and noise reduction has also become the focus of people's attention on subway construction, and has become the key to the sustainable development of urban rail transit construction. one. The vibration and noise produced by the passing of the train will still directly affect people's life and health, and also cause adverse effects on the surrounding environment to a certain extent. The heavy responsibility of vibration reduction technology in terms of vibration reduction and noise reduction falls on the rubber pad under the middle rail of the track fastener. [0003] In order to meet the new standards of QCR563-2017 spring...
