Problems solved by technology

[0003] At present, only simple and rough sound insulation treatment has been carried out on the power cabin, that is, coating a layer of damping colloid on the surface of the power cabin or using a separator mechanically filled with porous materials such as sponge and foam between two metal plates, while the entire power cabin Almost no effective protective measures have been taken for the heat insulation of the cabin, and the heat insulation and sound insulation performance cannot meet the requirements. At the same time, due to the integral structure, welding is required, the disassembly cycle is long, the maintenance of the power cabin is inconvenient, and the density is high, which cannot meet the requirements of the body. overall weight loss requirements

Abstract

A restrained damping heat and sound insulation device is characterized by comprising a sealed shell and heat and sound insulation functional composite materials filled in the shell. A preparation method of the restrained damping heat and sound insulation device includes preparation, assembly and sealing of the heat and sound insulation functional composite materials and the shell. Reliable connection between a sealing material and a heat and sound insulation plate is ensured, the end face and the periphery of a power cabin truss of an engine are doubly sealed and prevented from directly contacting with open flame, flame resistance and vibration resistance are high, the restrained damping heat and sound insulation device is fixed by screwing or riveting during assembly, welding deformation is avoided, and heat and sound insulation effects are ensured.

Description

technical field [0001] The invention relates to the field of functional composite materials, in particular to a constrained damping heat and sound insulation device and a preparation method thereof. Background technique [0002] Tanks and armored vehicles are the main equipment of light mechanized units and quick response units. They are widely used in anti-terrorism, peacekeeping and other occasions. With the increase of engine power, the heat and noise generated are getting bigger and bigger, causing the temperature of the engine compartment to reach 100 ℃ and above, the noise is as high as 117dB~121dB, causing the temperature in the cockpit to reach as high as 50℃~70℃, the temperature in the passenger cabin to reach above 40℃, and the noise to reach above 115dB, resulting in an extremely bad human-machine environment, which is harmful to the physical and mental health of drivers and passengers It causes great harm and seriously affects the normal performance of the tactic...
