The invention provides sound insulation cotton for automobile covers, and belongs to the technical field of automobile sound insulation cotton. The sound insulation cotton comprises a sound insulation cotton body. The sound insulation cotton body comprises a heat dissipation cushion layer, and a plurality of heat conduction columns are evenly arranged on the surface of the bottom face of the heat dissipation cushion layer. A sound insulation cotton layer is arranged on the bottom face of the heat dissipation cushion layer, a plurality of through holes are evenly formed in the surface of the sound insulation cotton layer, and the through holes correspond to the heat conduction columns in position. The heat conduction columns are sleeved with the sound insulation cotton layer through the through holes. A net-shaped heat conduction layer is arranged on the bottom face of the sound insulation cotton layer, a plurality of clamping rings are evenly arranged on the surface of the net-shaped heat conduction layer, the clamping rings correspond to the heat conduction columns in position, and the net-shaped heat conduction layer is connected with the heat conduction columns in a clamped mode through the clamping rings. Heat generated in the working process of an engine can be transferred out, and the sound insulation cotton layer is prevented from being damaged by heat accumulation.
