摘要

在聚合二苯基甲烷二异氰酸酯(pMDI)树脂中部分(10%至30%)替代大豆粉，大大减少了颗粒垫热压过程中的压板粘着。将大豆粉添加到固定剂量的pMDI中(而不是替代它)，可以在更大程度上减少压板粘连。大豆减少了固化pMDI的粘性，从而减少了树脂颗粒转移到压板的倾向。大豆对固化pMDI的减粘效果与对未固化pMDI的减粘效果形成对比，未固化pMDI的减粘效果增加了。

Soy Flour Substitution in Polymeric Diphenylmethane Diisocyanate Resin Reduces Press Platen Sticking

Partial (10% to 30%) substitution of soy flour in polymeric diphenylmethane diisocyanate (pMDI) resin substantially reduces platen sticking during hot-pressing of particle mats. Adding the soy flour to a fixed dose of pMDI (instead of substituting it) reduces platen sticking to an even greater extent. The soy decreases the tack of cured pMDI, thereby reducing the propensity of resinated particles to transfer to the platen. The tack reduction effect of soy on cured pMDI contrasts with its effect on uncured pMDI, where the cold tack is increased.

期刊介绍： Forest Products Journal (FPJ) is the source of information for industry leaders, researchers, teachers, students, and everyone interested in today''s forest products industry. The Forest Products Journal is well respected for publishing high-quality peer-reviewed technical research findings at the applied or practical level that reflect the current state of wood science and technology. Articles suitable as Technical Notes are brief notes (generally 1,200 words or less) that describe new or improved equipment or techniques; report on findings produced as by-products of major studies; or outline progress to date on long-term projects.
