摘要
研究丁苯橡胶(SBR)/轮胎再生橡胶(TRR)用量比对农业轮胎胎面胶性能的影响。结果表明:SBR和TRR总用量为80份或SBR用量为50份时,随着TRR用量增大,混炼胶的硫化速率增大,硫化胶的耐臭氧老化性能提高;SBR/TRR用量比为30/50,20/60和10/70时,炭黑在胶料中的分散性较好;SBR/TRR用量比为10/70时,硫化胶的压缩生热较低;SBR/TRR用量比为10/70和50/0时,硫化胶的耐热氧老化性能较好;SBR/TRR用量比为10/70时,胶料的综合性能较好。
The effect of styrene-butadiene rubber （SBR）/recycled tire rubber （TRR） blending ratio on the properties of tread compound of agricultural tire was studied. The results showed that, with increase of TRR amount, the curing rate of the compound increased and the ozone aging resistance of the vulcanized rubber were improved. When the SBR/TRR blending ratio was 30/50, 20/60 or 10/70, the dispersion of carbon black was good. When the SBR/TRR blending ratio was 10/70, the heat build-up was low. When the SBR/TRR blending ratio was 10/70 or 50/0, the thermo-oxidative aging resistance was good. It was found that the overall performance of the compound was better when the SBR/TRR blending ratio was 10/70.
