摘要

摘要: 研究了脲醛改性呋喃树脂合成过程中反应温度、甲醛与尿素的物质的量之比、pH值、加料方式及改性剂等因素对产品性能的影响,给出了合成高水分呋喃树脂的较佳工艺条件.通过工艺控制和添加改性剂,制得了树脂砂黏结强度为2.28MPa,水的质量分数为18.9%,游离甲醛的质量分数为0.23%,黏度(20℃)为31mPa·s,外观为棕红色透明液体的呋喃树脂.

Abstract: The influencing factors in the course of synthesis of furan resin modified by urea-formaldehyde resin, such as reaction temperatures, molar ratio of formaldehyde and urea, pH values, charging ways and the addition of modifying agents, have been studied.Meanwhile, a more proper processing condition of synthesis of furan resin with high water content has been found.The furan resin product is a brown transparent liquid, which has the performance:tensile strength 2.28 MPa, mass fraction of water 18.9%, mass fraction of free formaldehyde 0.23%, viscosity(20℃) 31 mPa·s.
