The invention discloses a composite transmission material for reducing impact sound and a preparation process thereof, relates to the technical field of composite materials, and solves the problem that the impact sound cannot be effectively reduced because a damping material only depends on the self foaming principle. The composition comprises the following components in parts by weight: 70-80 parts of a polyol polyester resin; 20-35 parts of organic silicon resin; 30-35 parts of expanded perlite powder; 25-30 parts of sepiolite powder; 15-20 parts of glass ceramic powder; 10-12 parts of ammonium phosphomolybdate; 1-3 parts of cycloprophane oil; 0.5-1.5 parts of zinc dialkyl dithiophosphate; 0.5-1.5 parts of quaternary ammonium salt; 0.3-0.7 parts of toner; 15-23 parts of a plasticizer; 2-6 parts of a stabilizer. The composite impact sound reduction transmission material can effectively reduce impact sound when being impacted greatly, and has good use effect. |
