Abstract

This study explored the feasibility of Waste Cooking Oil (WCO)‐based Bio‐Polyurethane (Bio‐PU) as an eco‐friendly alternative to petroleum‐derived polyols in plywood adhesives. The objective is to evaluate the impact of varied WCO concentrations and methylene diphenyl diisocyanate (MDI) levels on Bio‐PU and plywood performance. The Bio‐PU's characteristics, rheology, and functional groups are studied. Plywood made from three layers of 100 mm x 100 mm × 2 mm rubberwood (Hevea brasiliensis) veneer is bonded with Bio‐PU using a dual spread approach at 180 g.m−2, hot pressed at 120 °C and 1 MPa for 4 min. The laboratory‐fabricated plywood is tested for physical, mechanical, and adhesive properties. Results showed that Bio‐PU exhibited unique adhesive characteristics, with excellent adhesive strength, despite a slight decrease with higher WCO concentrations. WCO insertion do not compromise delamination resistance. FTIR analysis confirmed successful polyurethane chain synthesis. This research highlighted the potential of WCO‐based Bio‐PU's as a sustainable, high‐performance plywood adhesive.

改性烹饪废油中提取的生物多元醇制成的聚氨酯在户外级胶合板中的粘合力和内聚力性能

本研究探讨了以废食用油（WCO）为基础的生物聚氨酯（Bio-PU）作为胶合板粘合剂中石油衍生多元醇的环保型替代品的可行性。目的是评估不同 WCO 浓度和亚甲基二苯基二异氰酸酯 (MDI) 含量对生物聚氨酯和胶合板性能的影响。对生物聚氨酯的特性、流变性和官能团进行了研究。用 180 g.m-2 的双层铺展法将三层 100 mm x 100 mm × 2 mm 的橡胶木（Hevea brasiliensis）单板与 Bio-PU 粘合，并在 120 °C 和 1 MPa 的压力下热压 4 分钟。对实验室制造的胶合板进行了物理、机械和粘合性能测试。结果表明，Bio-PU 具有独特的粘合特性，尽管 WCO 浓度越高，粘合强度略有下降，但粘合强度极佳。插入 WCO 不会影响抗分层性。傅立叶变换红外分析证实了聚氨酯链的成功合成。这项研究强调了基于 WCO 的生物聚氨酯作为一种可持续的高性能胶合板粘合剂的潜力。
