摘要

This study has made the styrene butadiene rubber (SBR)/organoclay nanocomposite through the latex method by using the 3-aminopropyltriethoxysilane (APTES) and N,N-dimethyldodecylamine (DDA) as modifier and has studied the cure characteristics, swelling ratio, morphology, mechanical properties, and dynamic viscoelastic properties in order to evaluate the effect of APTES and DDA. Since the SBR/organoclay compound made with DDA has shown the fastest scorch time, optimal vulcanization time, and cure rate. In case of SBR/organoclay compound using APTES, we have measured the behavior of dynamic viscoellatic property according to the change in the strain amplitude in order to find out whether the covalent bond is formed between APTES and bis(triethoxysilylpropyl)tetrasulfide (TESPT). The dispersion of silicates with the rubber matrix was a little low since the polarity of silicates modified with APTES was relatively highter than that of the organoclay modified with DDA although APTES has formed a covalent bond with TESPT, and a low mechanical property values are shown. Consequently, the mechanical properties of the SBR/orgnoclay nanocmposite made with DDA were improved more than the compound made with APTES siince the vulcanizaiton effect by alkylamine and the dispersion of silicates within the rubber matrix was relatively excellent.
