摘　　要：研究了掺混树脂的用量对不同型号的PVC糊树脂发泡性能、黏度、力学性能、加工性能等的影响。结果表明:①对于发泡制品,掺混树脂的最佳替代比例为30%(质量分数);②加入掺混树脂可降低PVC增塑糊的黏度,且在放置时间为24h时黏度最大;③加入掺混树脂会降低PVC增塑糊的力学性能和加工性能。The effects of blending resin amount on the foaming properties, viscosities, me- chanical properties and processing properties of different types of PVC plasticized pastes were stud ied. The results showed that： the optimum substitution ratio of blending resins was 30% （mass fraction） for the foaming products; the viscosities of PVC plasticized pastes reduced af- ter adding blending resins, and the viscosities reached the maximum after 24-h standing; the mechanical properties and processing propcrtics of PVC plasticized pastes reduced after adding blending resins.
