本研究係以回收廢紙為原料經由添加不同比例之酚醛樹脂的方式做成板狀發泡體。文中探討紙漿發泡體加入酚醛樹脂後的成形、強力、透氣度、防火及吸水等物性。結果顯示酚醛樹脂添加比例在15%內,密度、尺寸安定性、拉伸強力、壓縮強力及彎曲強力有增加的情形,而透氣度及吸水性則呈減少的趨勢。隨著酚醛樹脂添加量的增加可提高其防火性,但添加量超過13%後則無明顯變化。
This research aims to mold pulp fiber into a foaming board and improve its physical properties with adding phenol-formaldehyde resin. In this paper, the experimental samples were made of pulp and phenol-formaldehyde resin with mixing by different ratio. We discussed the physical properties of the pulp fiber foaming board after adding phenol-formaldehyde resin to it, such as molding property, strength, air peameability, fireproof, and water absorption etc. The result shows that adding phenol-formaldehyde resin could change the physical properties of the pulp fiber foaming board when the ratio of phenol-formaldehyde resin was kept under 15%. The density, molding properity, tensile strength, compressed strength, and flexural strength would increase. The air peameaility and water absorption would decrease. As the adding of the phenol-formaldehyde resin, the fireproof would increase. When the ratio of the phenol-formaldehyde resin was more than 13%, the change of the fireproof was not much.
