本文对正确选择有机过氧化物可以改进弹性体的配炼工艺进行了论述,并对几种过氧化物对改善弹性体加工性能和硫化性能的作用进行了详尽介绍。DBPH-50-HP是一种独特的防焦烧过氧化物配方,当将其添加到FKM胶料中时,它可以解决与FKM弹性体有关的混炼和硫化问题。与对比过氧化物相比,它能延长混炼温度下的防焦烧时间一倍并具有相同的硫化性能。在177℃硫化温度下,可提高蛛网状模具填充系数(从DBPH-50的35%提高到DBPH-50-PH的75%),从而降低废品率。
In this paper, the correct choice of organic peroxides can be improved elastomer compounding process are discussed, and several peroxide to improve the elastomer processing performance and vulcanization performance are described in detail. DBPH-50-HP is a unique anti-scorch peroxide formulation that addresses the mixing and curing problems associated with FKM elastomers when added to FKM compounds. It extends the anti-scorch time at the compounding temperature by a factor of two and possesses the same vulcanisation properties as the comparative peroxide. At a curing temperature of 177 ° C, the cobweb mold filling factor (from 35% of DBPH-50 to 75% of DBPH-50-PH) can be increased, thus reducing the rejection rate.
