Silencing adhesive tape

The invention relates to a silencing adhesive tape, specifically relates to a high-strength silencing adhesive tape and belongs to the technical field of silencing adhesive tapes. The silencing adhesive tape disclosed by the invention comprises a matrix and a bonding layer coating on one surface of the matrix; and the matrix of the silencing adhesive tape contains the following components in partsby weight: 110-140 parts of silicon resin, 50-60 parts of highly-polymerized PVC, 10-20 parts of nanometer bone glue, 10-20 parts of chitin nanofibers, 3-8 parts of dahurian larch bark powder, 5-10 parts of a dispersant, 5-10 parts of a plasticizer and 5-10 parts of a solvent. The silencing adhesive tape is prepared by adding highly-polymerized PVC on the basis of taking the silicon resin as a main component, and therefore, that the prepared silencing adhesive tape has good rebound resilience and compression property can be ensured; and meanwhile, the added nanometer bone glue is used for improving the elasticity and
