Description
Technical field
The present invention relates to butyl reclaimed rubber series high-performance damping gluing agent material formula, particularly take butyl reclaimed rubber as matrix, the high performance material take damping imparting agent and mineral filler as additive.
Background technology
High polymer damping material is based on the visco-elasticity of superpolymer, and namely in the glass transition zone, the internal friction that is produced by molecular chain movement partly changes mechanical energy or the acoustic energy of outer field action into heat energy dissipation, and has the functional materials of damping noise reduction effect.In addition, the distinctive viscoelasticity behavior of macromolecular material makes colloid under less power effect, viscous fluid flow occur, and and formed Van der Waals force between glutinous thing, thereby produce higher bonding force, make it be used to sizing agent.
The temperature range of the glass transition of general homopolymer is narrow, and the temperature range that produces effective damping is roughly near second-order transition temperature ± and 10～15 ℃, the use temperature of material is limited in scope.The glass transition region． of rubber type of material occurs in below room temperature mostly, can not well satisfy the actual needs that use.Therefore, development use temperature a wider range and controlled damping material become this area technical problem in the urgent need to address.
Isoprene-isobutylene rubber is the multipolymer of polybutene and a small amount of polyisoprene, in its molecular structure, the methyl of a large amount of regular arrangements makes isoprene-isobutylene rubber have the advantages such as low air penetrability, Heat stability is good, damping performance are good, anti-ozone, is widely used in the fields such as aerospace cause, communications and transportation, mechanical means, construction work and daily life.Yet isoprene-isobutylene rubber due to self curability and self-adhesion not good enough, therefore make its application in the sizing agent field only limit to insulating glass sealant, the industry such as automobile sealed.
Along with a large amount of uses of isoprene-isobutylene rubber, the quantity of waste butyl rubber is also increasing.Reclaimed rubber is main path and the method that waste butyl rubber is recycled, and it is the rubber that has certain plasticity-and can again vulcanize, and with itself and rubber and use, can save rubber, and reduction power consumption of polymer processing and product cost are improved processing performance.And the butyl reclaimed rubber good processability, the very fast and operational safety of vulcanization rate generally can incipient scorch, is easy to mixing, calendering, and power consumption is few.
Butyl reclaimed rubber series high-performance damping gluing agent material has the damping capacity that is better than isoprene-isobutylene rubber, and has overcome the not good enough shortcoming of isoprene-isobutylene rubber material self-adhesion, has good damping capacity and adhesive property, is a kind of high performance damping sizing agent.
