The invention provides a sound insulation board for interior decoration of a railway passenger car and a preparation method and application of the sound insulation board. The sound insulation board for the interior decoration sequentially comprises a sound insulation board panel layer, a corrugated sandwich board layer and a sound insulation board lining board layer, wherein the corrugated sandwich board layer sequentially comprises a corrugated sandwich board upper-layer panel layer, a middle corrugated core layer and a corrugated sandwich board lower-layer panel layer. The sound insulation board panel layer comprises short carbon fibers and a flame-retardant material, and the corrugated sandwich board layer and the sound insulation board lining board layer respectively comprise basalt fibers and a flame-retardant material. The heat treatment method is adopted for preparing the sound insulation board for the interior decoration, the process is simple, the forming period is short, the production efficiency is high, the sound insulation board is applied to the railway passenger car, the sound insulation effect can reach 30 decibels or above, the requirement for light weight of the railway passenger car is met, the weight can be reduced by 20% or above, and meanwhile the strength, impact resistance and flame retardance of a door plate structure can be improved.
