摘要
通过差示扫描量热仪(DSC)对不同相对分子质量的酚醛树脂进行非等温和等温固化评价,并将达到相同固化度的酚醛树脂所需的时间与加入酚醛树脂胶料的焦烧时间进行对比研究。结果表明,在DSC等温模式下,通过处理固化曲线得到的酚醛树脂固化度与时间的变化关系曲线可以反应其固化的快慢,并与加入酚醛树脂胶料的焦烧时间变化趋势一致。
The non-isothermal and isothermal curing of phenolic resin with different molecular weight were evaluated by differential scanning calorimetry （ DSC ） , and the time required to achieve the same curing degree of phenolic resin and the scorch time of the rubber compound containing phenolic resin were comparatively studied. The results showed that under isothermal condition, the phenolic resin＇ s of curing degree and time relationship curve acquired by curing curve reflected the curing speed of the phenolic resin and it showed the same change trend as the scorch time of the compound containing phenolic resin.
