An asphalt damping sheet, which comprises the following components in indicated amounts based on the total mass of the asphalt damping sheet: a paint slag-containing waste limestone powder 20-50 parts; soft pitch 1-5 parts; hard pitch 11-15 parts; a non-metallic mineral 29-59 parts; PET short fiber 0.1-1.5 parts; and said non-metallic mineral is selected from the group consisting of quartz sand, pottery clay and mica powder. The technical process in the invention uses the paint slag-containing waste limestone powder generated in dry separation process of overspray adopted by vehicle manufacturer paint shops as filler in the asphalt damping sheets, such asphalt damping sheets can be used in the field of machine manufacturing such as automobiles and ships, and also can be used in the field of building waterproof materials, and the goal of resource recycling is achieved. |
