Abstract

To enhance the moisture resistance of wood adhesives, this work aims to add a branched co-monomer, such as tert-butyl acrylate, to polyvinyl acetate (PVAc) emulsion adhesive. This research focuses the development and testing of emulsion co-polymers containing vinyl acetate (VAc), vinyl neodecanoate (VeoVa), N-methylol acrylamide (NMA), and tert-butyl acrylate (Poly (VAc-VeoVa10-TBA-NMA)) as wood adhesives. Preservatives, plasticizer, polyvinyl alcohol (PVA) solution, and aluminum chloride solution are added to develop the emulsion-based adhesive samples. The VAc, VeoVa, methyl methacrylate (MMA) and NMA (Poly (VAc-VeoVa-MMA-NMA)) adhesive are then compared with the poly (VAc-VeoVa-TBA-NMA)-based adhesive sample. The EN 204–205 standard was followed in testing the tensile strength of bonded wood specimens in both wet and dry circumstances to evaluate the adhesives’ performance. When compared to a co-polymer-based adhesive based on MMA, EN 204 demonstrates that after 6 h of bonding, the tensile shear strength of a TBA-based adhesive increased by 25.31% in a dry environment and by 31.58% in a wet environment. The established approach provides a simple and useful way to produce adhesives with better water resistance and bonding strength by using TBA as a branching co-monomer.

丙烯酸叔丁酯（TBA）共单体基防水木材胶粘剂：合成与表征

为了提高木材胶粘剂的抗湿性，本研究旨在向聚醋酸乙烯酯（PVAc）乳液胶粘剂中添加支链共聚物，如丙烯酸叔丁酯。本研究的重点是开发和测试含有醋酸乙烯基（VAc）、新癸酸乙烯基（VeoVa）、n -甲基丙烯酰胺（NMA）和丙烯酸叔丁酯（聚（VAc- veova10 - tba -NMA））的乳液共聚物作为木材胶粘剂。加入防腐剂、增塑剂、聚乙烯醇（PVA）溶液和氯化铝溶液，形成乳化型胶粘剂样品。然后将VAc、VeoVa、甲基丙烯酸甲酯（MMA）和NMA （Poly (VAc-VeoVa-MMA-NMA)）粘合剂与Poly （VAc-VeoVa- tba -NMA）基粘合剂样品进行比较。按照EN 204-205标准测试粘接木材试样在湿和干环境下的抗拉强度，以评估胶粘剂的性能。与基于MMA的共聚物基胶粘剂相比，EN 204表明，在粘合6小时后，tba基胶粘剂在干燥环境下的拉伸剪切强度提高了25.31%，在潮湿环境下提高了31.58%。所建立的方法为以TBA为支链共聚物制备具有较好耐水性和粘接强度的胶粘剂提供了一种简单实用的方法。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
