精品 丁苯橡胶∕炭黑∕纳米凹凸棒土复合材料的制备及其性能研究 摘要：炭黑、白炭黑这些高能耗产品价格猛涨等因素的影响，在 HYPERLINK / \o 橡胶 \t _blank 橡胶工业制品中采用的原材料品种有变化的趋势，对无机浅色填料主要是天然无机填料的需求量迅速增大。由于对无机填料的需求急增，对新型填充材料的性能要求也随之有所扩大。而AT储量丰富，价格低廉，因而有很好的市场发展前景。凹凸棒土(简称凹土) 是一种天然纳米针状硅酸盐（Mg5Si8O20(OH2)4·4H2O），是一种具有层链状结构的含水富镁硅酸盐矿物。其晶体呈棒状或纤维状，长0.5-0.15μm，宽0.05-0.15μm，层内贯穿孔道，表面凹凸相间布满沟槽，因而具有较大的比表面积。凹土的矿物学组成和微观形态特点均为其作为 HYPERLINK / \o 橡胶 \t _blank 橡胶填充补强材料提供了可能性。此外，相对于炭黑、白炭黑这些传统填料，AT储量丰富，价格低廉，因而有很好的市场发展前景。因而，本文将硅烷偶联剂KH-560，KH-570 ，KH-590，Si-69偶联剂改性过的AT与丁苯橡胶(SBR)复合，制备出性能优异的AT/SBR纳米复合材料，并对其力学性能测试。研究结果对比表明，KH-590对AT的改性效果最好，再用KH-590改性后的凹凸棒土与炭黑不同比例混合填充丁苯橡胶，通过实验对其力学性能测试，结果表明当AT与炭黑并用比为3：2时，其拉伸强度、撕裂强度、扯断伸长率分别达到22.77MPa，74.20 KN/m和511%。与填充50份炭黑的丁苯橡胶的复合材料力学性能相媲美。因此，可考虑用AT与炭黑并用，来部分代替炭黑，从而降低橡胶制品的成本。 [关键词] 凹凸棒土 丁苯橡胶 偶联剂 炭黑 并用  Preparation and property investigation of the SBR/carbon black/nano-attapulgite composites Properties Yun-Long Yang Xuzhou Institute of Industry Technology [Abstract]: The carbon black and silica products, these high energy prices soared and other factors, in the rubber industry raw materials used in variety of products, there is a change in the trend of light-colored inorganic filler is mainly the demand for natural inorganic filler increases rapidly. Because of the surge in demand for inorganic filler, filler material on the performance of the new requirements also will be expanded. The AT rich reserves, low prices, which have good market prospects. Attapulgite (referred to as attapulgite) is a natural nano-silicate (Mg5Si8O20 (OH2) 4 ? 4H2O), is a kind of chain structure of the water-rich layer of magnesium silicate minerals. The crystals were rod-like or fibrous, long 0.5-0.15μm, width of 0.05-0.15μm, layer through the pores, uneven surface covered with white trench, which has a larger surface area. Au composition and mineralogy of soil morphology are characterized by a reinforcing material as a rubber offers the possibility of filling. Furthermore, compared with carbon black and silica filler these traditions,
