Abstract

The invention discloses a high-speed rail rubber microporous cushion and a manufacturing method thereof. The high-speed rail rubber microporous cushion which is composed of the following components in percentage by mass: 25-50% of synthetic rubber, 16-26% of reinforcing agent, 19-27% of filler, 1.2-2.4% of activator, 10-12% of plasticizer, 2.5-3.5% of foaming agent and 1.0-1.5% of crosslinking agent. The manufacturing method comprises the following steps: (1) compounding; (2) discharging; and (3) vulcanizing. The manufacturing method is simple. The prepared high-speed rail rubber microporous cushion has the advantages of favorable mechanical properties, excellent heat resistance, excellent aging resistance and excellent water resistance, and is suitable to be used under different climatic conditions in different areas.

Description

technical field [0001] The invention relates to a shock-absorbing pad and a manufacturing method thereof, in particular to a high-iron rubber microporous shock-absorbing pad and a manufacturing method thereof. Background technique [0002] In recent years, China's high-speed railway has developed at an astonishing speed. In the medium and long-term railway planning by 2020, the total length of China's four-vertical and four-horizontal passenger dedicated line network will reach 16,000 kilometers. A large number of high-speed trains and climate conditions in different regions have put forward higher requirements on the shock absorption performance and service life of railways. The original rubber mat can no longer meet its requirements, and the heat resistance, aging resistance, water resistance, mechanical properties, chemical medium resistance, weather resistance and other aspects of the rail shock absorber must be continuously improved and improved.
