改性微晶纤维素的制备及其对丁苯橡胶性能的影响

研究微晶纤维素（MCC）和改性微晶纤维索（MMCC）对丁苯橡胶（SBR）各项性能的影响．结果表明：当MCC和MMCC用量均为20份时，SBR硫化胶的拉伸强度最大，分别为15.3和19.0 MPa；填充MMCC的SBR胶料的阿克隆磨耗量比填充MCC的SBR胶料降低了41%；填充20份MCC和MMCC的SBR胶料具有相似的玻璃化温度。;The properties of microcrystalline cellulose（MCC）and modified microcrystalline cellulose（MMCC）filled SBR were studied. The results showed that，when the addition levels of MCC and MMCC were 20 phr，the SBR vulcanizates had maximum tensile strength（15.3 and 19.0 MPa，espectively）.Compared with the MCC filled SBR vulcanizate.the Akron abrasion loss of MMCC filled SBR vulcanizate was 41% lower.The SBR vulcanizates filled with 20 phr MCC and MMCC had a similar glass transition temperature
