description The invention discloses a soft damping plate for vibration absorption and noise reduction. The soft damping plate is prepared from the following raw materials in weight portion: 45 to 50 portions of asphalt as a base stock; and 18 to 20 portions of waste rubber powder, 24 to 31 portions of mud powder and 4 to 5 portions of fine sand which are used as fillers; 2 to 3 portions of polypropylene as atemperature resistant additive; and glass fibre cloth as a tire base adopts. The materials are extruded and molded through heating a stirring machine. The soft damping plate for vibration absorption and noise reduction is prepared through adopting raw materials with wide source and low price and new mixture ratio. Through actual measuration, the wasting factor of the soft damping plate reaches over 0.5; noise can be reduced by over 10 decibels; the effect of vibration absorption and noise reduction belongs to upper intermediate degree; and under the condition of equivalent noise reduction, the cost of the soft damping
