密炼工艺对木质素基酚醛树脂纤维性能的影响
The influence of compounding process on the properties of lignin-based phenol-formaldehyde resin fibers
摘要
Abstract
Lignin,with its phenolic hydroxyl groups,can be used to replace phenol in the synthesis of thermoplastic lignin phenol-formaldehyde resin.Lignin phenol-formaldehyde resin was used as a raw material to prepare phenol-formaldehyde resin fibers,and the effects of compoun-ding time,compounding temperature,and compounding speed on the mechanical properties of the fibers were studied.Prolonged compounding time,high compounding temperature,and fast compounding speed can result in significant friction and heat generation between resin mixers,leading to resin pyrolysis due to excessive heat.This leads to a decrease in resin viscosity and molecular weight,thereby affecting the mechanical properties of the fibers.The optimal compounding process for the resin was found to be a compounding time of 15 minutes,a compounding speed of 45 rad/min,and a compounding temperature of 135℃.关键词
