| 中文摘要: |
| 研究试验温度和停放时间对胶料加工性能的影响。结果表明，试验温度对胶料的门尼粘度、门尼焦烧时间和硫化特性均有一定影响。门尼粘度测定的试验温度选择100 ℃；门尼焦烧时间测定的试验温度一般选120 ℃，SBR胶料可提高至130 ℃左右，以缩短试验时间；硫化特性测定的试验温度一般选185 ℃。试验前模腔达到规定温度后再保持15 min，以使转子与模腔温度一致。胶料停放时间应控制在2 h左右。 |
| 英文摘要: |
| The influence of the test temperature and conditioning time on the processibility of rubber compound was investigated.The results showed that the test temperature had certain influence on the Mooney viscosity,Mooney scorch time and curing behavior of rubber compound;100 ℃ should have been chosen to determine the Mooney viscosity;120 ℃ or 130 ℃ for SBR should have been chosen to determine the Mooney scorch time in order to shorten the test time;185 ℃ should have been chosen to determine the curing behavior;the temperature of the mold cavity should have been kept for 15 min when it raised up to the specified value to make the rotor temperature in accordance with the temperature of the mold cavity;and the conditioning time should have been 2 h. |
