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，从硫酸盐法制浆过程产生的黑液中分离和提纯木质素。从这个过程中分离出的木质素具有巨大的潜力，可以作为加拿大纸浆厂的一种新的高价值产品。**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。这项提案**旨在将木质素加入胶粘剂配方中。有两种方法被认为是很有前途的：一种是通过水基工艺的**淀粉基胶粘剂配方，另一种是通过自由基聚合技术作为压敏**胶粘剂(PSA)配方的组份。淀粉型粘合剂通常**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。该项目的目的不仅是为了说明木质素作为一种增值产品的用途**，而且是为了用一种基于生物的资源取代传统的石油成分。**渥太华的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。杜贝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、聚合物表征和粘合剂性能测试方面**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.**
