Study On The Interaction Between And Carbon-Black And SSBR

The interaction between SSBR and carbon-black is studied which include physical interaction and chemical interaction. Carbon-black is the main filler for rubber products. The characters of carbon-black which include particle size specific surface area and chemical surface groups and so on decide the interaction between SSBR and carbon-black. The subject provide theory basis for the use of carbon-black and the modify of carbon-black.The properties of SSBR filled different type of carbon-black are different. The type of interaction and contribution to mechanical properties are studied by testing the bound rubber in and not in NH3 and compare the mechanical properties after and before processed in NH3. The result show that the interaction contain physical interaction and chemical interaction, when the particle size of carbon-black become smaller, the chemical interaction increase while the physical interaction decrease and the mechanical properties increase. There exists a critical particle size near 100nm. In this subject, RPA is used to character the processing properties which include the influence of type of carbon-black and amount of carbon-black on the Payne effect. And the dependence G' G'' and tan of the type of carbon-black and the amount of carbon-black.The influence of carbon-black on the cross-link density of SSBR is studied by Magnetic Resonance Crosslink Density Spectrometer which include physical cross-link density and chemical cross-link density. We can get the influence law of carbon-black on the interaction between SSBR and carbon-black by analyzing the physical cross-link density and on the rubber vulcanization by analyzing the chemical cross-link density.The influence of carbon-black on vulcanization of rubber is studied by MFK. When the particle of carbon-black becomes smaller, the Ea of vulcanization decreases and the time used to vulcanization become shorter in the same condition. The detail of the vulcanization of rubber at different temperature can also be predicted. The thermo stability of SSBR filled different type of carbon-black is studied by MFK and the detail of thermal decomposition of SSBR can be predicted at some temperature.
