Manufacturing method of sound insulation baffle plate, sound insulation baffle plate and high-speed train

Abstract

The invention provides a manufacturing method of a sound insulation baffle plate, the sound insulation baffle plate and a high-speed train. The method comprises the following steps: step (1) cleaning: performing cleaning treatment on a baffle plate sectional material; step (2) pre-spraying coating: spraying sound insulation damping coating on the surface of the baffle plate sectional material treated in the step (1) so as to form a sound insulation coating layer with the thickness of 40-50 microns on the surface of the baffle plate sectional material; step (3) pre-drying: performing drying treatment on the sound insulation coating layer of the baffle plate sectional material treated in the step (2); step (4) spraying coating: continuously spraying the sound insulation damping coating on the baffle plate sectional material dried in the step (3) so as to further form a sound insulation coating layer with the thickness of 200-300 microns on the surface of the baffle plate sectional material; step (5) drying: performing the drying treatment on the sound insulation coating layer on the baffle plate treated in the step (4); and step 6) sequentially repeating the step (4), namely spraying the coating, and the step 5), namely drying, till the thickness value of the sound insulation coating layer on the baffle plate sectional material is in the range of 2.5-3.5mm so as to form the sound insulation baffle plate.

Description

Technical field [0001] The invention relates to mechanical equipment for passenger cars, in particular to a method for manufacturing a soundproof baffle, a soundproof baffle and a high-speed train. Background technique [0002] At present, rail passenger cars are commonly used vehicles in people's daily life. With the continuous development of listing technology, high-speed trains are widely used in passenger transportation. When a high-speed train is running on the track, the vibration and noise generated between the wheels and the rail will be transmitted to the car through the floor. Excessive noise will affect the rest of the passengers and even affect the normal conversation of the passengers. In order to reduce the noise generated by wheels and rails from being transmitted into the car, the high-speed train in the prior art is provided with a baffle at the connection between the floor and the side wall. On the one hand, the baffle serves to block external water from the con...
