전이금속 산화물이 SBR 가교에 미치는 영향 = Effect of transition metal oxide for SBR vulcanization

다국어 초록 (Multilingual Abstract)

Sulfur and accelerator of the factors determining the physical properties of vulcanized rubber are changed largely to the cross-linking density and type of rubber. Cross-linking of the rubber is formed mainly by the sulfur, and reacting dose and the rate of the vulcanization reaction is determined by the action of a catalyst and activator.
In general, SBR may be a compound using a compounding ingredient similar to NR. However, SBR is good to apply strong vulcanization accelerator or active vulcanization accelerator due to slow vulcanization than NR. SBR can be blended with diene rubber same NR, IR, BR. The many styrene content of the polymer is widely used by blending with diene-based rubber for the purpose of improving the abrasion resistance and hardness at the same time lowering the specific gravity.
In this study, the adsorbed active oxygen on the oxide using a transition metal oxide are the experiment involved in cross-linking, when cross-linked SBR were investigated for cross-linking effect by the addition of a transition metal oxide, and to provide the basic database in the art. First, determine the characteristics of the transition metal oxide prepared by a transition metal selected one transition metal oxides, the mechanical properties by selected transition metal oxide production process and changes in the content and pH conditions were compared to measurements. And through chemical analysis such as XRD(X-ray Diffractometer) and FT-IR(Fourier Transform Infrared Spectroscopy) and DSC(Differential Scanning Calorimeter), it was to confirm some of the properties studied the effect of transition metal oxide.
