The invention discloses a vibration and noise reduction polyimide foam heat insulation composite material for a ship cabin and a mounting method. The material comprises a primer, a damping coating, apolyimide heat insulation foam board, a flame-retardant white cloth and a putty layer which are sequentially adhered to the inner wall of a cabin. The mounting method comprises the following steps that firstly, the primer is brushed on the inner wall of a cabin; secondly, the damping coating is brushed; thirdly, the polyimide heat insulation foam board is laid; fourthly, the flame-retardant whitecloth is laid; fifthly, putty is brushed and coated. The heat conductivity coefficient of the polyimide heat insulation foam board is smaller than or equal to 0.040 W/m.K, the limit oxygen index is larger than or equal to 32%, and the flame resistance reaches the V-0 level. The material has good vibration and noise reduction effects, does not increase the weight burden of the ship and is extremelyhigh in safety.
