摘要
以生物油、苯酚及多聚甲醛为原料制备出可发性生物油-酚醛树脂,通过正交实验法优选出最佳合成工艺,采用FTIR表征了其产物结构,并测定了由此树脂制备出的生物油-酚醛泡沫材料的性能。结果表明,适宜制作泡沫材料的生物油-酚醛树脂的最佳合成反应条件如下:多聚甲醛与苯酚物质的量比为2.2∶1,生物油添加质量分数20%,NaOH与苯酚物质的量比为0.35∶1,反应时间20 min。该树脂具有较高活性和更多醚键。以其制备的生物油-酚醛泡沫综合性能良好,可用于建筑保温材料。
The foamable bio -oil phenolic resin was prepared using bio -oil, phenol and paraformaldehyde as raw materials. The optimal synthesis process was determined by orthogonal experiment. The product structure was char- acterized by FFIR. The properties of the bio - oil phenolic foam from the product were tested. The results showed that the optimum synthesis conditions of bio - oil - phenolic resin suitable for foam were as follows ： molar ratio of poly formaldehyde to phenol 2.2： 1, bio - oil mass fraction 20%, molar ratio of NaOH to phenol 0. 35：1 and reac- tion time 20 min. The resin had high activity and more ether bonds. The phenolic foam from the product resin had good comprehensive performance and could be used for building insulation materials.
