Problems solved by technology

[0003] Generally speaking, the expansion-type vibration-damping rubber has a foaming structure, which is easy to absorb water. If the water absorption rate of the expansion-type vibration-damping rubber is too high, the vibration-damping rubber will absorb a large amount of water due to weather and other reasons during the actual use of the vehicle, resulting in vibration reduction. The aging of the glue or the corrosion of the steel plate by moisture will affect the beautification and even threaten the safety

Abstract

The invention discloses low-water-absorption-rate expansion vibration-damping glue, belongs to the technical field of expansion vibration-damping glue, and mainly solves the problem of high water absorption rate of the expansion vibration-damping glue in the prior art. The low-water-absorption-rate expansion vibration-damping glue is mainly characterized by including 10-40 parts of liquid polybutadiene; 0-10 parts of solid rubber; 0-20 parts of a softener; 0-10 parts of a tackifier; 0-10 parts of sulfur; 0-10 parts of a promoter; 0.1-3 parts of an antioxidant; 0.1-10 parts of an active agent; 0-3 parts of a foaming agent; 0-15 parts of parts of a film forming agent and 10-50 parts of a filler. The low-water-absorption-rate expansion vibration-damping glue has the advantages of significant reduction of water absorption rate of cured expansion vibration-damping glue with other properties remained basically unchanged, and can be widely used in bonding and filling between stiffening beams and outside plates of welding assembly line auto-body cover panels, and can play the role of buffering and vibration-damping.

Description

technical field [0001] The invention belongs to the technical field of expansion and vibration damping glue, and in particular relates to an expansion and vibration damping glue with low water absorption. Background technique [0002] In the automobile body manufacturing process, the combination of the outer panel and the reinforcement beam of the body cover is usually assembled by welding, such as the roof reinforcement beam of the body cab, the engine cover reinforcement beam and the trunk lid reinforcement beam, etc. and the outer panel Combination, all adopt welding method. Because there is a certain gap between the cover plate and the reinforcing beam, noise may be generated due to vibration during driving, and the welding spots on the cover plate also seriously damage the smoothness of the appearance. In order to overcome the above shortcomings, the expansion type vibration-damping adhesive can be coated on the stamped sheet and the reinforced beam structure before we...
