摘　　要：在国家大力发展绿色低碳经济的背景下,充分利用林木生物质资源生产功能性树脂意义重大。为降低3D打印用光敏树脂的成本并改善其性能,采用林木生物质热裂解产生的生物油来部分替代苯酚合成新型双酚F型酚醛环氧树脂,并替代部分商用树脂制备混杂型光敏树脂,重点探究了添加量对树脂黏度和3D打印试件性能的影响。考察了后处理工艺对试件力学强度的影响,成功打印出多个平面和立体镂空样品。结果表明:林木生物油的引入降低了光敏树脂的黏度和线性收缩率,提升了3D打印材料的拉伸强度。此外,后处理进一步提高了生物油混杂光敏树脂打印件的力学性能。以林木生物油为原料制备生物基光敏树脂,不仅拓宽了林木衍生资源的利用途径,而且为光固化3D打印行业提供一种新型低成本的绿色环保新材料。In the context of the country's efforts to develop a green and low-carbon economy,making full use of wood-based biomass resources is important for reducing carbon emission and environmental protection.In order to reduce the cost and improve the properties of photosensitive resin for 3D printing,in this paper,phenol was partially replaced by bio-oil to synthesize bisphenol F epoxy resin,which was then mixed with commercial photosensitive resin to produce a hybrid photosensitive resin.The effects of the addition amount on the viscosity of UV resin and the properties of 3D printed samples were evaluated.Planar and hollow 3D samples were successfully printed.Results showed that addition of bio-oil reduced the viscosity,linear shrinkage,and also improved the tensile strength.Posttreatment enhanced the tensile strength of bio-oil hybrid UV resin printed samples.Using bio-oil to synthesize biobased photosensitive resins gave more possibilities to the application of wood-derived resources and also provided a new low-cost and environmental friendly photosensitive resin for 3D printing industry.
