Abstract

Studies were conducted on the effects of filler loading and 3-aminopropyltriethoxysilane (SCA) on the physical characteristics of epoxidized natural rubber (ENR)-alumina nanoparticles composites (ENRAN). The filler loading varied from 10, 20, 30, 40, 50, and 60 phr in the absence and presence of 2 phr SCA in every formulation. The alumina nanoparticles have a positive interaction with the ENR matrix since they increase the glass transition temperature of the composites [Mohamad, N., Muchtar, A., Ghazali, M.J., Dahlan, H.M. and Azhari, C.H. (2008). The Effect of Filler on Epoxidized Natural Rubber-Alumina Nanoparticles Composites, Eur. J. Sci. Res., 24: 538—547]. The addition of SCA decreased the maximum torque (MH) and the torque difference (MH-ML) of ENRANs compound as well as causing the curing process to occur at a very fast rate. The spherical alumina particles were dispersed in ENR matrix and a uniform particle distribution was observed under scanning electron microscope enabling the increase of the torque values in the composites.

填料用量和硅烷偶联剂对环氧化天然橡胶-氧化铝纳米复合材料物理特性的影响

研究了填料和3-氨基丙基三乙氧基硅烷(SCA)对环氧化天然橡胶(ENR)-氧化铝纳米复合材料(ENRAN)物理性能的影响。在每种配方中，在没有和存在2 phr SCA的情况下，填料的负荷从10、20、30、40、50和60 phr不等。氧化铝纳米颗粒与ENR基体有积极的相互作用，因为它们增加了复合材料的玻璃化转变温度[Mohamad, N.， Muchtar, a .， Ghazali, m.j.， Dahlan, H.M.和Azhari, C.H.(2008)]。填料对环氧化天然橡胶-氧化铝纳米复合材料的影响。j .科学。[j].自然科学与技术，2008,24(4):538-547。SCA的加入降低了ENRANs化合物的最大扭矩(MH)和扭矩差(MH- ml)，并使固化过程发生得非常快。球形氧化铝颗粒分散在ENR基体中，在扫描电镜下观察到均匀的颗粒分布，使复合材料的转矩值增加。
