摘要
研究补强树脂间苯二酚SL-R80/六甲氧基甲基三聚氰胺树脂(HMMM)、间苯二酚-甲醛树脂SL-3020LFR/HMMM、酚醛树脂SL-2101/六亚甲基四胺(HMT)和高苯乙烯树脂S-6-H在全钢轮胎中的应用。结果表明:4种补强树脂对胶料的硫化均有延缓作用,其中采用SL-R80/HMMM的胶料t90最长,采用SL-2101/HMT的胶料t90最短;与空白胶料相比,只有采用S-6-H的胶料的t5延长,其余胶料均缩短;采用SL-3020LFR/HMMM的胶料加工流动性变差,其余胶料变化不大;4种补强树脂均能有效提高胶料硬度,其中SL-R80/HMMM的提高效果最佳;4种补强树脂对胶料的拉伸强度和拉断伸长率的影响都很小,但对撕裂强度有负面影响,其中SL-R80/HMMM的影响最大,SL-3020LFR/HMMM的影响最小;S-6-H树脂对胶料的生热基本没有影响,其他3种树脂均有负面影响,其中SL-3020LFR/HMMM的影响最大。
The application of reinforcing resin resorcinol SL-R80/hexamethoxymethylmelamine resin(SL-R80/HMMM),resorcinol formaldehyde resin SL-3020 LFR/HMMM,phenolic resin SL-2101/hexamethylene tetramine(SL-2101/HMT) and high styrene resin S-6-H,in all-steel tire were studied.The results showed that all four kinds of reinforcing resins had a delaying effect on the vulcanization of the compound. Among them,the t90 of SL-R80/HMMM compound was the longest,and that of SL-2101/HMT compound was the shortest. Compared with blank compound,the t5 of the compound with S-6-H was extended,and the rest of the compounds was shortened. The flow property of the compound with SL-3020 LFR/HMMM was poor,and the rest did not change. The four kinds of reinforcing resins could effectively improve the hardness of the compound,of which SL-R80/HMMM compound had the best improvement effect. The four kinds of reinforcing resins had little effect on the tensile strength and elongation at break of the compound,but they had a negative effect on the tear strength,of which SL-R80/HMMM had the greatest impact,and SL-3020 LFR/HMMM had the least impact. Resin S-6-H had no effect on the heat build-up of the compound,while the other three kinds of reinforcing resins had negative effects,of which SL-3020 LFR/HMMM had the greatest impact.
