摘要/Abstract

摘要： 对比分析了添加羟甲基脲(MMU)、丙二醇碳酸酯(PC)、碳酸钠(Na₂CO₃)3种单组分固化剂及其复配固化剂的酚醛(PF)树脂的凝胶时间、适用期及固化性能。结果表明:单组分和复配两类固化剂添加到酚醛树脂后凝胶时间至少缩短了74 s,但添加固化剂PC及MMU+PC后PF树脂黏度在3 h内由初始的178 mPa·s增加到18 000和9 000 mPa·s左右,黏度增加过快,不符合胶合板生产至少4 h适用期的要求;复合固化剂MMU+Na₂CO₃显著降低PF树脂固化反应的起始和峰顶温度,实现低温快速固化同时符合人造板适用期要求,是一种可用于胶合板生产的PF树脂快速固化剂。

Abstract: The gel time, pot life and curing properties of phenol-formaldehyde resin (PF) resins induced by single curing agents, namely methylolureas (MMU), propylene carbonate(PC), sodium carbonate (Na₂CO₃), and their hybrid were investigated. The results demonstrated that the gel times of PF resins induced by single curing agent and two kinds of their counterpart hybrid curing agents were shortened by at least 74s. However, the viscosities of PF resins in presence of PC and MMU+PC increased to 18 000 and 9 000 mPa·s from 178 mPa·s in 3h respectively, and the pot lifes were too short to meet the production requirement of 4 hours at least. The curing agents MMU+Na₂CO₃ had significant effect on lowering the onset and peak temperature of curing reaction. Thus the aim of fast curing of PF resin, and the needs of production were achieved. Therefore, the curing agent of MMU+Na₂CO₃ was suitable for fast curing at lower temperature in plywood production.

Key words: phenol-formaldehyde resin, curing agent, fast curing
