The invention relates to the technical field of automobile parts, in particular to a composite multi-effect automobile heat insulation plate which comprises a heat insulation plate body and long flowguide grooves. The heat insulation plate body comprises a heat insulation base layer, a heat insulation protection layer and a sound insulation layer, and the heat insulation protection layer is arranged above the heat insulation base layer and comprises heat insulation mortar and microporous ceramic balls; a reinforcing metal grid is arranged above the heat insulation protection layer, the upperportion of the reinforcing metal grid is coated with a noise reduction damping layer, and a sound insulation layer is arranged above the noise reduction damping layer. A second noise reduction dampinglayer is arranged above the sound insulation layer, and the outer side of the noise reduction damping layer is coated with a heat conduction layer; the section of the heat insulation plate body is ofa continuous waveform structure, and a plurality of long flow guide grooves are formed in the heat insulation plate body at intervals. The composite multi-effect automobile heat insulation plate is simple in structure and high in functionality, has the effects of heat insulation protection and noise reduction, and is high in stability and pressure resistance.
