摘要
研究巨型工程机械子午线轮胎的变温硫化工艺。结果表明:与传统硫化工艺相比,采用变温硫化工艺(加热时间/保压时间比为1/1. 07)的巨型工程机械子午线轮胎胶料过硫化程度降低,物理性能提高;变温硫化工艺能提高巨型工程机械子午线轮胎硫化均匀性,解决局部过硫严重的问题;采用变温硫化工艺,调整加热时间与保压时间比,有利于提高巨型工程机械子午线轮胎性能和生产效率,节约能源。
Non-isothermal curing process of giant OTR radial tire was studied. The results showed that,compared with the traditional curing process,giant OTR radial tire cured with non-isothermal process(heating time/dwell time ratio was 1/1. 07) had a lower degree of over curing and better physical properties,nonisothermal curing process could improve vulcanization uniformity and solve the problem that some parts were over cured seriously. By adjusting the heating time/dwell time ratio during non-isothermal curing process,properties and production efficiency of giant OTR radial tire were improved,and the energy consumption of the production process was reduced.
