MRI: Acquisition of Instrumentation for Interdisciplinary Research and Training on Production and Characterization of Bio-based Adhesives from Swine Manure

1040246 Fini本提案要求提供资金，用于高压反应堆、加压鼓泡测试和光学Wilhelmy设备，以通过对猪粪水热处理获得的生物油进行化学修饰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。初步结果表明，猪粪水热处理可用于生产生物粘合剂，但由于其粘度和剪切模数较低，所生成的粘合剂只能部分替代石油基粘合剂。为了将生物粘合剂设计成独立的粘合剂，还需要进一步的加工。为此，将使用真空蒸馏和化学处理，然后聚合生物粘合剂，以开发具有所需机械和流变性的粘合剂，用于建筑和包装行业。因此，美国每年生产的530万吨猪粪可以供应约400万桶生物粘合剂，用于混凝土面板接缝、粘结剂锚固系统、高速公路和机场沥青路面、屋顶、工业地毯、包装、高速公路分界线安装和土壤稳定。

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.
