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可用于Foundry Core Sands的基于胶原蛋白的粘合剂。 核心在铸铁产品中创建空心腔。核心由二氧化硅砂和核心粘合剂组成。 目的是替代使用酚氨基烷或呋喃 /甲苯的基于石油的粘合剂。 该胶原蛋白提供了一种从美国食品加工来源创建可持续粘合剂的方法，否则该粘合剂主要被丢弃。 与常规石油基粘合剂相比，胶原蛋白粘合剂将释放出约20-30％的挥发性有机化合物。 这里的工作将集中于辨别一个有利的交联链，该交联链将导致一条胶原蛋白链化学结合相邻的链。 这将增加粘合剂的强度，并在浸入水中的情况下使其不易变软，就像施加核心洗涤时一样。 初步结果表明，当使用1％基于胶原蛋白的粘合剂时，交联将产生的粘合剂每平方英寸的拉伸强度为300-400磅。这项变革性研究旨在为铸造厂提供一种减少污染的手段，同时提供高质量的铁铸件。 这将帮助铸造厂成为当地社区的好邻居，同时维持美国重要的制造业工作。 这项研究将为胶原蛋白在包括药物，环境吸附剂和电子产品在内的广泛应用中使用。 这项研究和发展将获得博士学位。曾在铸造行业工作的候选人。 在这个角色中，这位学生通过其他由NSF资助的项目设计了一种减少铸造砂废物的方法。 作为可交付的，结果将通过卷发期刊论文和会议演讲广泛传播。 此外，与Foundry合作伙伴一起，随后的目的是在演示规模或全面测试这些基于胶原蛋白的粘合剂。本项目由民用，机械和制造创新部的材料加工与制造计划共同资助。并通过工业创新和合作伙伴部行业计划的学术联络机会。
