Description
One, technical field
The present invention relates to a kind of isoprene-isobutylene rubber/poly-(methyl) acrylate composite damping material and preparation method thereof, belong to Polymer Synthesizing and forming process field.
Two, background technology
Isoprene-isobutylene rubber is owing to just have two symmetrical substituent methyls every a carbon atom on the pib molecule segment, and the substituting group number is many, and the lax resistance of segment is big, and the in-fighting peak height is a kind of traditional damping material.But the maximum damping value of isoprene-isobutylene rubber appears at-30～-40 ℃, and in the time of 0 ℃, damping value is on the low side, more than 10 ℃, is close to the forfeiture damping function, has reduced near the effective damping function of isoprene-isobutylene rubber room temperature widely.In order to widen near the effective damping functional zone of isoprene-isobutylene rubber room temperature, have a lot of experts and scholars isoprene-isobutylene rubber to be carried out improvement in performance both at home and abroad by grafting, compatibilizing and co-mixing and dynamic vulcanization etc.:
Isoprene-isobutylene rubber and other rubber such as natural rubber, chloroprene rubber, the terpolymer EP rubber blend can improve the processing characteristics of isoprene-isobutylene rubber significantly, and gives isoprene-isobutylene rubber good thermotolerance, oil-proofness and mechanical property.But this blend belongs to rubber-rubber blend, and is because the second-order transition temperature of two kinds of rubber is more or less the same, little for the influence of the effective damping function temperature province of isoprene-isobutylene rubber.Luo Quan Kun professor has reported the research (≤China Synthetic Rubber Industry 〉=magazine 2004.NO.1) of isoprene-isobutylene rubber and chloroprene rubber blend, and the result shows that its blend compatibility is good, an in-fighting peak occurs in the time of 0 ℃, but is difficult to its maximum damping value (tan δ
Max) move to higher temperature province again.Kioura, Renzo etc. have reported research work (J.Appl.Polym.Sci., 1999,74 of isoprene-isobutylene rubber/polymeric amide being carried out compatibilizing and co-mixing with the two segmented copolymer, 3548), the result shows: expanding material has significant improvement effect to the consistency of the two, and the phase farmland that shows as Compatibilized blends reduces, and physical and mechanical properties improves greatly, but, because polymeric amide damping value itself is not high, causes its high-temperature zone damping value still on the low side, tan δ
Max≤ 0.15.T.C.Chang, W.Janvikul and R.Bernard etc. are at USA Magazine Polymer, 1995, report in 36 (18), on the isoprene-isobutylene rubber main chain, pass through free radical grafting methyl methacrylate etc., two complete isolating in-fighting peaks appear in this graft copolymer on its dynamic mechanical spectra, cause mixture damping function district discontinuous.
Carrying out dynamic vulcanization with polypropylene, is a research focus that improves the isoprene-isobutylene rubber performance.But, give birth at Polymer according to Taiwan's scholars Liao Fu, 1994,35 (12) middle reports, in chlorinated butyl rubber/polypropylene blend, because the effect of thermal stresses, polypropylene changes (T to liquid-liquid of isoprene-isobutylene rubber
H) restraining effect is arranged, cause its maximum damping value tan δ
Max＜0.35, be difficult to satisfy application requiring to damping noise reduction.
Three, summary of the invention
