This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The Small Business Innovation Research Phase I project aims at improving the reaction yield in synthesizing a new resin monomer material. The monomer was found to be processed to polymeric thermosetting resins useful for replacement of current urea-formaldehyde resins used as binders of various interior grade wood composite boards because of their excellent capability of reducing the formaldehyde emission levels of boards. Formaldehyde emission reduction or elimination from wood composite boards has been called for by general public as well as by various government regulations. There is currently no good commercial alternative binder resin system available to meet impending government regulations. For further development of the new resin system to the pilot plant and then to the commercial stage, the chemical synthesis method for the resin monomer material needs to be improved significantly in the laboratory. The proposed research aims to investigate the chemical synthesis method of the monomer by carrying out a series of reactions and measuring the yields of the product and byproducts to obtain the most optimum synthesis reaction parameters. The objective of research is to reach the chemical synthesis reaction yield of 95% or higher along with minimal associated costs of reaction. The Small Business Innovation Research Phase I project aims at expediting the commercialization of a new resin technology by optimizing the manufacturing process of monomer and thereby lowering the overall manufacturing cost. The new resin technology will enable the interior grade wood composite board industry to significantly reduce the formaldehyde emission levels of boards below the regulation levels. The industry will be able to continue the manufacturing of otherwise well-accepted wood composite boards, converting low value wood wastes into high-value wood composite boards. Further, the low formaldehyde emission of wood composite boards will directly result in significant health benefits to the public as well as lowering of environmental pollution. The proposed research and resultant implementation of the resin technology will enhance the technological understanding on the chemical and physical mechanisms of formaldehyde emission generally occurring in the hot press manufacturing of wood composite boards using UF resins. Relationship of the mole ratio of formaldehyde vs. functionality of base monomer of resins and resultant strength properties of boards and formaldehyde emission levels will be more clearly understood, which may lead to improvements in technologies that further reduce the formaldehyde emission levels of wood composite boards in the future.

该奖项由2009年美国复苏和再投资法案（公法111-5）资助。小企业创新研究第一阶段项目旨在提高合成新型树脂单体材料的反应产率。 发现该单体被加工成可用于替代目前用作各种室内级木材复合板的粘合剂的脲醛树脂的聚合物热固性树脂，因为它们具有优异的降低板的甲醛释放水平的能力。 公众和各种政府法规都要求减少或消除木质复合板的甲醛排放。目前没有良好的商业替代粘合剂树脂系统可用于满足即将到来的政府法规。为了将新树脂体系进一步开发到中试工厂，然后进入商业阶段，需要在实验室中显著改进树脂单体材料的化学合成方法。本研究的目的是通过进行一系列的反应，并测量产物和副产物的产率，以获得最佳的合成反应参数，研究单体的化学合成方法。研究的目的是以最小的反应相关成本达到沿着的95%或更高的化学合成反应产率。 小企业创新研究第一阶段项目旨在通过优化单体的制造工艺，从而降低整体制造成本，加快新树脂技术的商业化。新的树脂技术将使室内级木质复合板行业能够将板材的甲醛释放量大幅降低到法规水平以下。该行业将能够继续生产其他广受欢迎的木材复合板，将低价值的木材废料转化为高价值的木材复合板。此外，木质复合板的低甲醛释放将直接导致对公众的显著健康益处以及降低环境污染。拟议的研究和由此产生的树脂技术的实施将提高对甲醛释放的化学和物理机制的技术理解，通常发生在热压制造的木材复合板使用脲醛树脂。甲醛摩尔比与树脂基础单体官能度的关系以及由此产生的板材强度性能和甲醛释放水平将得到更清楚的理解，这可能导致未来进一步降低木质复合板甲醛释放水平的技术改进。
