摘要

超薄高密度纤维板作为纤维板行业的新兴产品，因其超薄的厚度（＜1.5 mm）在胶合板贴面、建筑装饰装修等饰面领域广泛应用。以酚醛树脂（PF）为胶黏剂，探讨热压时间（60、90和120 s）和热压温度（150、170和190 ℃）变化对1 mm厚PF超薄高密度纤维板的弯曲强度、内结合强度和24 h吸水厚度膨胀率的影响，并使用扫描电子显微镜观察纤维和树脂结合状况。研究结果表明，在一定范围内随着热压时间的延长和热压温度的升高，纤维板的性能逐渐提高；当热压时间为120 s，热压温度为190 ℃时，纤维板的性能最优，其弯曲强度达到88.5 MPa，内结合强度达到5.70 MPa，24 h吸水厚度膨胀率为6.8%，达到团体标准T/CNFPIA 3007—2019《超薄高密度纤维板》的要求。

Abstract

As a new product in the fiberboard industry, ultra-thin high density fiberboards have been widely used as veneers for the plywood furnishing, architectural decoration, and other fields because of the ultra-thin thickness (about 1.5 mm). In this study, phenol-formaldehyde resin (PF) was used as an adhesive to investigate the effects of the hot-pressing time (60, 90, and 120 s) and temperature (150, 170, and 190 ℃) on the modulus of rupture, internal bonding strength, and the 24 h water absorption thickness swelling rate (24 h TS) of 1 mm PF ultra-thin fiberboards. The scanning electron microscope was used to observe the bonding situation between fiber and resin. The results showed that with the extension of the hot-pressing time and the increase of hot-pressing temperature within a certain range, the performance of fiberboards was gradually improved. When the hot-pressing time was 120 s and the hot-pressing temperature was 190 ℃, the performance of fiberboards was the best. The modulus of rupture reached 88.5 MPa. The internal bonding strength reached 5.70 MPa and the 24 h TS was 6.8%. These properties meet the requirements of the standard T/CNFPIA 3007—2019 ,Ultra-Thin High Density Fiberboard,.
