【摘要】 <正>硅藻土是一种生物成因的硅质沉积岩,其化学成分主要是非晶质SiO₂,具有细腻、松散、质轻、多孔、吸水和渗透性强等特点,硅藻土具有广泛的用途。本文采用硅藻土作为补强剂,制备得到具有特殊功能的天然橡胶/硅藻土复合材料,以其部分取代传统天然橡胶的补强剂炭黑和白炭黑。更多还原

【Abstract】 The research paper reports the successful development of a natural rubber composites reinforced with unmodified and modified diatomite.Its vulcanizing property、mechanical property、thermal resistance property and dynamic mechanical property are investigated.The results show that the t₁₀、t₅₀ and t₉₀ increase,but their ranges are very limited;The effect of diatomite reinforcement is best as adding 10phr modified diatomite,and the tensile strength reachs30.373 MPa,which is 14.56% larger than that of NR;The thermal resistance property of diatomite reinforced NR attains enhancement;The diatomite reinforced NR has higher glass-transition temperature（Tg） and storage modulus（E′）、loss modulus（E″）,increasing its cross-linked rubber’s rigidity and toughness.更多还原
