1040246FiniThis proposal requests funding for a high pressure reactor, a pressurized blister test and an optical Wilhelmy device to produce bio-adhesives through chemical modification and polymerization of bio-oil obtained from hydrothermal processing of swine manure. Swine manure will be converted to biomonomers by hydrolysis and then further converted by chemical synthesis to biodegradable polymers like polylactic acid. Preliminary results showed hydrothermal processing of swine manure can be used to produce bio-adhesive; however, due to its low viscosity and shear modulus, the resultant adhesive can only be used as partial replacement for petroleum based adhesives. To engineer bio-adhesive to be used as a stand alone adhesive further processing is needed. To do so, vacuum distillation and chemical processing followed by polymerization of bio-adhesive will be used to develop adhesives with desired mechanical and rheological properties for applications in construction and packaging industries. Therefore, the 5.3 million tons of swine manure produced in the U.S. annually can supply around four million barrels of bio-adhesive to be used in construction of joints in concrete panels, adhesive anchorage systems, highway and airport asphalt pavements, roofing, industrial carpeting, packaging, installation of highway delineators, and soil stabilization.

1040246.该提案要求资助一个高压反应器、一个加压起泡试验和一个光学Wilhelmy装置，以通过对从水热处理猪粪中获得的生物油进行化学改性和聚合来生产生物粘合剂。猪粪将通过水解转化为生物单体，然后通过化学合成进一步转化为可生物降解的聚合物，如聚乳酸。初步研究结果表明，猪粪水热处理可用于生产生物胶粘剂，但由于其粘度和剪切模量低，所得胶粘剂只能作为石油基胶粘剂的部分替代品。为了设计生物粘合剂以用作独立粘合剂，需要进一步加工。为此，将使用真空蒸馏和化学加工，然后聚合生物粘合剂，以开发具有所需机械和流变性能的粘合剂，用于建筑和包装行业。因此，美国每年生产的530万吨猪粪可提供约400万桶生物粘合剂，用于混凝土面板接缝的施工，粘合剂锚固系统，高速公路和机场沥青路面，屋顶，工业地毯，包装，高速公路轮廓标的安装和土壤稳定。
