Abstract

The invention relates to a high speed train damping sound insulation sheet material and a manufacturing method thereof. The sheet material consists of a sound insulation main body damping basal layer, a damping seam gum layer and a resin fiber layer. The manufacturing method comprises the following steps: firstly, mixing raw material components of the sound insulation damping basal layer in percentage by weight, putting the mixture into an internal mixer to perform mixing operations, and discharging the materials; secondly, transferring the discharged rubber materials into a mixing mill to perform hot mixing; thirdly, sending the rubber materials after the hot mixing into a calender to perform calendering operations to manufacture rubber sheets; fourthly, coating a damping adhesive on the rubber sheets, and adhering resin fibers to the damping adhesive; and finally, transferring the rubber sheets coated with the damping adhesive and the resin fibers into a coating and drying compound machine to coat a binding agent, and simultaneously packaging release paper outside the binding agent. The manufacturing method can obtain a damping sound insulation material which obviously reduces vibrations and noise radiations of sheet material structures and other components on a carriage of a high speed train.

Description

technical field [0001] The invention relates to a sound-insulating sheet and a manufacturing method thereof, in particular to a damping sound-insulating material for high-speed locomotives and a manufacturing method thereof. Background technique [0002] Nowadays, people's material, cultural and living standards have been developed by leaps and bounds, especially in my country's transportation industry, and the speed of trains has been increased many times. In recent years, the speed of high-speed trains has reached 300 kilometers per hour. It is convenient and quick for people to travel from south to north. Although the well-developed transportation has provided many conveniences for people's travel, the noise from various locomotives, especially high-speed locomotives, has seriously affected people's physical and mental health. In order to provide people with a good working and living environment, effective measures must be taken. In recent years, many manufacturers and ...
