木质素改性热塑性酚醛树脂中试装置的设计

Design on Pilot Plant of Lignin Modified Thermoplastic Phenolic Resin

根据木质素改性热塑性酚醛树脂产品生产工艺的要求,研制设计了一套年产1 kt木质素改性热塑性酚醛树脂中试装置,经过监测,本工艺配方和装置生产的木质素改性热塑性酚醛树脂软化点89-95℃、聚合速度78-95 s、流淌度72 mm,完全达到了模塑料用木质素酚醛树脂的要求,选择经过液化降解的木质素参与合成的热塑性酚醛树脂,具有良好的分子结构和固化性能。

According to the request of the production process of lignin modified thermoplastic phenolic resin product,researched and designed a set of pilot plant of lignin modified thermoplastic phenolic resin,the annual output was 1000 tons.Through monitoring,the softening point of the lignin modified thermoplastic phenolic resin produced by this process,formula and device was 89~90℃,the polymerization speed was 78~95 s,the flowing degree was 72 mm,which completely reached the requirement of moulding compound for lignin in modifing phenol resin,the synthetic resin using lignin after lique faction degradation had good molecular structure and curing performance.
