Abstract

The invention provides a self-adhesion sound-insulating expansion adhesive. The adhesive comprises the following components in parts by weight: 100 parts of butyl rubber, 300-500 parts of filler calcium carbonate, 30-50 parts of processing oil, 70-100 parts of polyisobutylene, 10-30 parts of tackifying resin, 2-5 parts of an anti-aging agent, 10-20 parts of carbon black, 10-15 parts of expanded microbeads, and 2-4 parts of a cobalt salt. A preparation method of the adhesive comprises the following steps: performing kneading on the butyl rubber and a part of filler calcium carbonate in a kneading machine for 10 min, adding the polyisobutylene, the anti-aging agent, the carbon black, the processing oil and the remaining filler calcium carbonate, and performing kneading for 30 min; adding thetackifying resin and the cobalt salt, and continuing kneading for 30 min; adding the expanded microbeads, and performing kneading for 1 h; and performing extrusion through a screw extruder, performing calendaring, and performing lamination to obtain the self-adhesion sound-insulating expansion adhesive. The adhesive provided by the invention has good initial stickiness when being in contact withother parts; and the adhesive does not have crosslinking, and can continuously maintain excellent binding performance under high-temperature conditions.

Description

technical field [0001] The invention belongs to the technical field of expansion glue, and in particular relates to a self-adhesive sound-insulating expansion glue and a preparation method thereof. Background technique [0002] Most of the traditional sound-proofing expansion rubber for automobiles uses EPDM (ethylene propylene diene monomer) as the main body, adding various additives, fillers, and cross-linking agents, and is formed by banburying and molding. The knot layer is bonded to the automotive part. Prior art has following defect and deficiency: [0003] 1. The current sound-insulating expansion glue and auto parts mainly rely on adhesives. First, the cost of adhesives is relatively high. At the same time, several production processes are added in the production process, which increases the processing cost and operation difficulty; secondly, the use of In the process, the failure of the combination of the adhesive and the expansion glue may occur, which reduces th...
