摘要

本研究係以孟宗竹（＂phyllostachys pubescens＂, Mosobamboo）加工廢料、酚醛樹脂、混合型阻燃劑、對甲苯磺酸（p-Toluene sulfonicacid）、己烷（Hexane）等原料，以發泡方式製成各種耐燃竹粒片板，並探討其相關物性及耐燃性能'所得結果歸納如下：竹／酚醛樹脂製成之耐燃竹粒片板，在掃描式電子顯微鏡觀察下，顯示竹粒片與酚醛樹脂有良好之結合性及完整之封閉式泡孔，其平均密度為0.49 g/cm^3，平均含水率為10.5%；8mesh以上含30%未經阻燃劑處理竹粒片板之力學及物理性質比未添加竹粒片之盼酷樹脂耐燃板佳，其彎曲強度、內緊強度、木螺釘保持強度及吸水厚度膨脹率皆符合CNS 2215粒片板標準，而吸濕性則符合CN S8629之規定。經CNS 6532試驗結果知，竹粒片未分類或8mesh以上者及合20%及30%經阻燃劑處理者所製成之竹／酚醛樹脂耐燃板均可達CNS 6532耐燃三級之規定。熱重量損失分析（TGA）結果顯示，經阻燃處理之竹粒片含有較高之焦炭量，且隨竹粒片含量增加其焦炭含量亦隨之增加。未經／經阻燃劑浸潰之兩種竹粒片以TGA分析後之焦炭量，使用FTIR分析得知，所剩之C-O焦炭類物質可能為纖維素與半織維素之殘留物，顯示添加經阻燃劑浸潰處理之竹粒片於酚醛樹脂耐燃板對其耐燃性能具有正面影響。

The study was based on foaming method to manufacture the fire-retardant bamboo board (FREB) that synthesized from Moso bamboo residues, phenol formaldehyde resins (PF), fire retardants, p-Toluene sulfuric acid, and hexane. The objective of this study is to investigate the fire-retardant performance and the related characterization of various FRBBs. The results obtained are summarized as follows: FRBB was observed using scanning electron microscope (SEM). The SEM photographs showed a good combine condition as well as complete close foams hole for bamboo particles with PE The average density was 0.49 g/cm^3. The average Moisture content was 10.5%. The mechanical and physical properties of the particles over 8 mesh without processing fire retardants were better than the PF fire-retardant board without bamboo particles. Their Bonding Strength, internal bond strength (IB), screw holding (SH) and water absorption was corresponded with CNS 2215,the hygroscopic were corresponded with CNS 8629. The results from the tests of CNS 6532 showed that FRBB with all mesh particles and amount of 20 % and 30 % particles with fire-resistant treatment were able to reach the third grade of CNS 6532. From the results of TGA, a char was higher for FRBB with the bamboo particle processing with fire-retardants, and the more the amount of bamboo particle, the great the char. The char from the particle with/without fire retardants after the tests of the TGA was estimated to the tests of FTIR showed that some of C-O group was still existed. This char residues possible come from hemicellulose or cellulose, so that FRBB added with bamboo particles was a positive effect.
