Incorporation of lignin in adhesive formulations

BC Research Inc.（BCRI）及其母公司NORAM Engineering and Constructors开发了一种专有工艺，用于从硫酸盐制浆过程产生的黑液中分离和纯化木质素。从这一过程中分离出的 ** 木质素具有作为加拿大纸浆厂米尔斯新的高价值产品的巨大潜力。**他们正在寻找将这种高质量的木质素融入新的商业产品的方法。该提案 ** 寻求将木质素掺入粘合剂制剂中。两种方法已被确定为有前途的：通过水基工艺的淀粉基粘合剂配方，以及通过自由基聚合技术作为压敏粘合剂（PSA）配方中的组分。淀粉基粘合剂通常用于瓦楞纸板和包装应用，而PSA产品包括标签，胶带和保护膜。该项目的动机不仅是说明木质素作为增值产品的用途，而且是用生物基资源取代传统的石油基成分。uOttawa聚合物反应工程研究设施非常适合粘合剂的合成，** 表征和最终产品测试。Dubé教授和他的研究团队 ** 在多组分乳液聚合、纳米复合材料生产、聚合物 ** 表征和粘合性能测试方面经验丰富。**

BC Research Inc. (BCRI), with its parent company NORAM Engineering and Constructors, have developed a**proprietary process to isolate and purify lignin from black liquor generated from the Kraft pulping process. The**lignin isolated from this process has significant potential as a new high-value product for Canadian pulp mills.**They are seeking ways to incorporate this high quality lignin into new commercial products. This proposal**seeks to incorporate lignin in adhesive formulations. Two approaches have been identified as promising: a**starch-based adhesive formulation via a water-based process, and as a component in pressure-sensitive**adhesive (PSA) formulations via free-radical polymerization techniques. Starch-based adhesives are commonly**used in corrugated cardboard and packaging applications while PSA products include labels, tapes, and**protective films. The motivation of the project is to not only illustrate the use of lignin as a value-added**product but to displace traditional petroleum-based components with a bio-based resource.**The uOttawa polymer reaction engineering research facilities are uniquely suited to the synthesis,**characterization and end-product testing of adhesives. Prof. Dubé and his team of researchers are**well-experienced in multicomponent emulsion polymerization, nanocomposite production, polymer**characterization and adhesive property testing.**
