中文摘要 | 本研究旨在探討以苯乙烯-丁二烯橡膠乳液(SBR)為主劑之膠合劑,應用於天然木化粧合板之單板貼面膠合之適用性。本試驗所使用之膠合劑是由水性SBR乳液,配合適當之PMDI(Polymeric diphenylmethane diisocyanate)交聯劑及填充劑(高筋澱粉、玉米澱粉)所組成的一種膠合劑。此膠合劑有優良的膠合強度,不僅能全面改善木材膠合劑游離甲醛釋出之問題,也可提升耐冷熱反覆乾裂循環數和耐沸水性,且符合天然木化粧貼面合板Type-I試驗(JAS-1999第3條特殊天然木化粧合板)之合格要求,也提高了木材加工品質。又從膠合劑之黏度經時變化的試驗結果得知,其可使用時間可長達3小時,符合天然木化粧合板之單板貼面膠合製程之現場作業條件,極具實用性。 |
英文摘要 | The main purpose of this study was to investigate the process of making fancy plywood by using Styrene-Butadiene Rubber adhesive. The adhesive components included SBR latex, PMDI crosslinking agent, and filler. The adhesive exhibited excellent bonding strength. It not only solved the problem of free formaldehyde releasing, but also improved the cyclic cold-hot cycle test and boiling water-resistance. Using the non-formaldehyde SBR adhesive for natural fancy plywood could meet the regulation of Type I test as specified in Article 3 of JAS-1999 of special natural fancy plywood standard. The pot life property is greater than 3 hours, which demonstrated that it could be used in manufacturing site, therefore it is worthy of practical application. |
