Abstract

The present invention relates to a low VOC content expansion vibration-reduction rubber, and belongs to the technical field of expansion vibration-reduction. A purpose of the present invention is mainly to solve the problem of high VOC content in the existing expansion vibration-reduction rubber. The low VOC content expansion vibration-reduction rubber is mainly characterized by comprising 10-40 parts of liquid polybutadiene, 2-10 parts of a solid rubber, 5-15 parts of a plasticizer, 3-10 parts of sulfur, 2-10 parts of an accelerator, 0.1-3 parts of an antioxidant, 1-10 parts of an activator, 0.5-3 parts of a foaming agent, 0-1 part of a pigment, and 30-60 parts of a filler. According to the present invention, the VOC content of the expansion vibration-reduction rubber after curing can be significantly reduced while other performances are basically unchanged, the low VOC content expansion vibration-reduction rubber can be widely used for welding and filling between the outer plate and the strengthening beam of the welding wire vehicle body covering member so as to provide the buffer vibration-reduction effect, and volatiles and precipitates do not exist so as not to cause adverse effects on the vehicle body compartment odor.

Description

technical field [0001] The invention belongs to the technical field of expansion damping glue. In particular, it relates to an expansion and vibration damping rubber with low VOC content. 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 solder joints 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 welding. After bei...
