Abstract

The invention relates to the technical field of auto parts, in particular to a composite multi-effect heat insulation board for automobiles, which includes a heat insulation board body and a long diversion groove; the heat insulation board body includes a thermal insulation base layer, a heat insulation protection layer and a sound insulation layer , a thermal insulation protective layer is arranged above the thermal insulation base, and the thermal insulation protective layer includes thermal insulation mortar and microporous ceramic balls; a reinforced metal grid is arranged above the thermal insulation protective layer, and a noise reduction damping layer is coated on the reinforced metal grid , a sound-insulating layer is arranged above the noise-reducing damping layer; a second layer of noise-reducing damping layer is arranged above the sound-insulating layer, and a heat-conducting layer is coated on the outside of the noise-reducing damping layer; A plurality of diversion long grooves are arranged at intervals on the heat insulation board body; the invention has simple structure, strong functionality, functions of heat insulation protection and noise reduction, and has strong stability and pressure resistance.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a composite multi-effect heat insulation board for automobiles and a preparation method thereof. Background technique [0002] Automobile body insulation board, also known as heat shielding board, is a metal sheet placed between adjacent surfaces in order to reduce the damage of radiation heat transfer surface to other parts in heat transfer engineering. The body heat shield is generally arranged on both sides of the engine and above the exhaust pipe channel at the bottom of the body. It mainly uses the principle of reflection and heat insulation of the heat shield to cut off the transfer of heat, and it also has a certain effect of local noise insulation. [0003] The heat transfer process of automobile heating parts to the interior of the car body is very unstable, and is greatly affected by factors such as ambient temperature, wind speed, and the motion state of the car it...
