The objective of this award is to develop a collagen-based binder that can be used in foundry core sands. Cores create the hollow cavities within cast iron products; and the cores are comprised of silica sand plus a core binder. The aim is to replace petroleum-based binders that use phenolic urethane or furan / toluene. The collagen offers a means of creating a sustainable binder from a US food processing source that is otherwise mostly discarded. The collagen binder will release about 20-30% as much volatile organic compounds into the air, when compared to the conventional petroleum-based binders. The work herein will focus on discerning a favorable cross-linker that will cause one collagen strand to chemically bind to neighboring strands. This will increase the strength of the binder, and render it less susceptible to softening when immersed in water, as when applying a core wash. Preliminary results show that a cross-linker will yield a binder that hosts a tensile strength of 300-400 pounds per square inch, when 1% collagen-based binder is used. This transformative research aims to provide a means for foundries to diminish pollution while delivering high-quality iron castings. This will help the foundries be good neighbors in the local communities, while maintaining important manufacturing jobs in America. The research will open the way for collagen to be used in a broad range of new applications that include medicine, environmental sorbents, and electronics. This research and development will engage a Ph.D. candidate who has worked in the foundry industry. In this role, this student devised a means to cut foundry sand waste, via other NSF-funded projects. As a deliverable, the results will be widely disseminated via refereed journal papers and conference presentations. Also, with foundry partners, the subsequent aim is to test these collagen-based binders at the demonstration-scale or full-scale.This project is jointly funded by the Materials Processing & Manufacturing Program, of the Civil, Mechanical, and Manufacturing Innovation Division and by the Grant Opportunities for Academic Liaison with Industry Program of the Industrial Innovation and Partnerships Division.

该奖项的目的是开发一种可用于铸造芯砂的胶原基粘结剂。 型芯在铸铁产品内形成空腔;型芯由硅砂和型芯粘合剂组成。 其目的是取代使用酚醛聚氨酯或呋喃/甲苯的石油基粘合剂。 胶原蛋白提供了一种从美国食品加工来源中创造可持续粘合剂的方法，否则大多会被丢弃。 与传统的石油基粘合剂相比，胶原粘合剂将释放约20-30%的挥发性有机化合物到空气中。 本文的工作将集中在辨别一个有利的交联剂，将导致一个胶原链化学结合到相邻的链。 这将增加粘合剂的强度，并使其在浸入水中时不易软化，如在施加芯清洗时。 初步结果表明，当使用1%的胶原基粘合剂时，交联剂将产生具有300-400磅/平方英寸的拉伸强度的粘合剂。这项变革性的研究旨在为铸造厂提供一种在提供高质量铸铁件的同时减少污染的方法。 这将有助于铸造厂成为当地社区的好邻居，同时保持美国重要的制造业工作岗位。 这项研究将为胶原蛋白在医学、环境吸附剂和电子产品等广泛的新应用中的应用开辟道路。 这项研究和开发将聘请一位博士。在铸造行业工作过的候选人。 在这个角色中，这个学生设计了一种方法来减少铸造砂废料，通过其他NSF资助的项目。 作为一项交付成果，其结果将通过参考期刊论文和会议介绍广泛传播。 此外，与铸造合作伙伴，后续的目标是在示范规模或全尺寸测试这些胶原基粘合剂。该项目由土木，机械和制造创新部门的材料加工制造计划和工业创新和合作伙伴关系部门的学术联络与工业计划的资助机会共同资助。
