| 摘 要： | 采用两种化学组成相对含量不同,矿物组成和微观形貌差异明显的粉煤灰:即普通粉煤灰(PC灰)和固硫灰(CFB灰)补强丁苯橡胶,并对复合材料的各项性能进行了研究。试验结果表明:CFB灰补强丁苯橡胶复合材料的100%定伸应力、拉伸强度、断裂伸长率、撕裂强度性能优于PC灰。由于絮状CFB灰表面疏松多孔,相较光滑密实的球形PC灰,其与丁苯橡胶存在更多交联点,有利于提升复合材料性能。复合材料硬度随粉煤灰添加量的增加而提高。经硅烷偶联剂活化后粉煤灰具有更好的补强效果。

| Abstract: | Abstract: Two typical samples, normal fly ash (PC ash) and circulating fluid bed ash (CFB ash)?respectively, with different chemical compositions, mineral components and micro-structures, were used to filled Styrene Butadiene Rubber (SBR) , and properties of SBR composites were investigated. The results showed that: CFB ash has a better reinforcing effect than that of PC ash. There are many porous in the surface of CFB ash, hence it has more cross-linking points with SBR compare to that of PC ash. It is beneficial to improve the properties, such as 100% modulus, tensile strength, elongation at break and tearing strength of CFB/SBR composites. Hardness reinforced of SBR composites were increased with fly ash addition. Silane coupling agent modified fly ash has better reinforcement effect than original ash. |
