Study On Different Kinds Of Addition Agent Influence For Damping Polymer Performance

Different kinds of addition agent influence for damping polymer performance were studied by analyzing three experiments. First, the effect of new type filler(hollow microphere)with different kinds and different weight fraction on property of isobutene-isoprene damping rubber was studied. Secondly, the effect of different kinds of and different Phr. low molecular compounds on property of some damping polymer was studied. Thirdly, using organic hybrid of chlorinated polyethylene and low molecular compounds to improve damping properties of polymer. Mooney viscosity, vulcanization curve, tensile strength, lag losing, rebound resilience, aging properties and dynamic viscoelastic properties of vulcanized were measured.The result showed that the mixture filled different type and different weight fraction hollow microphere expressed different effect .The mixture with lOOmesh hollow microphere had better damping property. Even along with the increase of the quantity (10.20.30.phr),the rebound resilience diminish ,the damping property was relatively better.The damping property of mixture was affected by different kinds and different Phr. of low molecular compounds. Among the compounds, the rebound resilience of the mixture filled accelerative DZ(N,N-Dicyclohexyl-2benzothiazole sulphenamide) and anti-aging RD(Polymerized 2,2,4-trimethyl-l,2-dihydroquinoline) was littler. Other general properties are better too.Polymer with high damping property could be made by using organic hybrid of chlorinated polyethylene and low molecular compounds. The loss tangent (tg δ ) for the mixture is over 0.98 in a certain temperature range, some are over 1. As added PS, tg δ diminished a bit, but the thermo transmogrification could be improved. While added SBS, the damping peak widened, but tg δ diminished more. Added short nylon and polyester fiber, the rebound resilience of the mixture did not decline more. Added a certain weight white carbon black and Si69, the rebound resilience peak widened obviously and the rebound resilience declined.
