This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The research objective of this Grant Opportunity for Academic Liaison with Industry (GOALI) award is to devise a low volatile organic carbon (VOC) core binder that is comprised of a collagen-alkali silicate hybrid. The use of these binders can save energy and money in foundry processes, while diminishing their petroleum dependence. We aim to replace conventional petroleum-based binders, which cause significant volatile organic carbon pollution. Collagen is the triple-helical protein structure that comprises animal tendons and hides; and collagen has the tensile strength of steel. Collagen releases 15-25% as much VOC pollution as do phenolic urethanes in a foundry setting; and silicates release negligible amounts of VOCs. Together, collagen-alkali silicate hybrids favorably offer the promise of good thermal integrity, high tensile strength, good casting quality, and good shake-out, as discerned from preliminary results. To accomplish the research objectives, we will prepare collagen-alkali silicate bindered cores with an array of collagen-to-silicate proportions, mixing protocols, and curing processes. Per foundry criteria, we will appraise these relative to their resistance against molten iron erosion; and their tensile strength, hardness, shakeout propensity, and thermal integrity. Also, per fundamentals, we will characterize bonding by infrared analysis, nuclear magnetic resonance, and electron microscopy. These fundamental characterizations will steer the collagen-alkali silicate chemistry and processing protocol, so as to select the most favorable binder system.The expected benefits of this research will be to initiate a transformative rewriting of adhesives chemistry based on new metrics. The new metrics are to pursue US petrochemical independence with environmentally benign manufacturing, while devising sustainable products from bio-resources. This research will also expand fundamentals of adhesives and nitrogen chemistry; thermal effects on collagen and alkali silicates; curing kinetics; waterproofing; and environmental and industrial engineering. In addition to these important impacts this GOALI project team will conduct full-scale demonstrations of these collagen-alkali silicate binders at the HMAC-Lawrenceville, PA foundry, providing tremendous industrial value for the community.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该学术与工业联络资助机会 (GOALI) 奖的研究目标是设计一种由胶原蛋白-碱金属硅酸盐混合物组成的低挥发性有机碳 (VOC) 核心粘合剂。 使用这些粘合剂可以在铸造过程中节省能源和金钱，同时减少对石油的依赖。 我们的目标是取代传统的石油基粘合剂，这种粘合剂会造成严重的挥发性有机碳污染。 胶原蛋白是三螺旋蛋白质结构，由动物肌腱和兽皮组成；而胶原蛋白具有钢铁般的抗拉强度。 在铸造环境中，胶原蛋白释放的 VOC 污染比酚醛聚氨酯高 15-25%；硅酸盐释放的挥发性有机化合物的量可以忽略不计。 从初步结果可以看出，胶原蛋白-碱硅酸盐混合物有望提供良好的热完整性、高拉伸强度、良好的铸造质量和良好的落砂效果。 为了实现研究目标，我们将通过一系列胶原蛋白与硅酸盐的比例、混合方案和固化工艺来制备胶原蛋白-碱硅酸盐粘合芯。 根据铸造厂标准，我们将评估它们对铁水侵蚀的抵抗力；及其拉伸强度、硬度、落砂倾向和热完整性。 此外，根据基础知识，我们将通过红外分析、核磁共振和电子显微镜来表征键合。 这些基本特征将指导胶原-碱硅酸盐化学和加工方案，从而选择最有利的粘合剂系统。这项研究的预期好处将是基于新指标对粘合剂化学进行变革性重写。 新指标旨在通过环境友好的制造来追求美国石化的独立性，同时利用生物资源设计可持续产品。 这项研究还将扩展粘合剂和氮化学的基础知识；对胶原蛋白和碱金属硅酸盐的热效应；固化动力学；防水；以及环境和工业工程。除了这些重要影响之外，GOALI 项目团队还将在宾夕法尼亚州 HMAC-劳伦斯维尔铸造厂对这些胶原碱硅酸盐粘合剂进行全面演示，为社区提供巨大的工业价值。
