摘要
采用乳液共混法,用少量淀粉等量替代炭黑,制备淀粉/炭黑/丁苯橡胶(SBR)复合材料,研究了淀粉用量对复合材料抗疲劳性能的影响。结果表明,当丁苯胶乳为100份、炭黑与淀粉的总量为50份时,淀粉最佳替代量为5～8份,在此条件下复合材料的抗疲劳性能大幅度提高;淀粉/炭黑/SBR复合材料的抗疲劳性能与硫化胶的抗切割性能、裤形撕裂强度以及损耗因子有一定的相关性。
Starch/carbon black （ CB ）/styrene-bu- tadiene rubber（SBR） composites were prepared by emulsion blending with small amount of starch equiv- alently replacing CB, and the effect of starch amount on fatigue resistance of the composites was investiga- ted. The results showed that the optimum replacing amount of starch was 5 -8 phr when styrene-butadi- erie latex was 100 phr, the total amount of CB and starch was 50 phr. Under this condition, the fatigue resistance of starch/CB/SBR composites was im- proved evidently. The fatigue resistance of starch/ CB/SBR composites had cutting resistance, trouser tot.
