用间歇冷—热—冷法压制竹木复合结构长材 王传耀 杨文斌 陈刚 （福建农林大学材料工程学院，福建 福州 350002） 摘要 ：研究用间歇冷—热—冷法压出竹木复合结构连续长材的加工方法。试验采用竹集成层为表板与木单板层积层为次中板、竹丝集成层为中间芯板的5层对称均衡组坯工艺；设计装配一条间歇冷—热—冷热压长材生产线；试验工艺采用正交试验法，得出板厚17mm使用UF胶时的较佳工艺为热压温度120℃、单位压力2.4Mpa、热压时间16min（使用喷蒸装置可显著缩短至11min）、双面施胶量240g/㎡，达到试验预期较优指标。 关键词：竹木复合材料；结构用长材；加工工艺；设备;喷蒸装置 中图分类号：TS653.929 Study on the processing the long Bamboo-Wood Composite Materials, using method of the cold-hot-cold. press WANG Chuan-yao, YANG Wen-bin, CHEN Gang (College of Materials Engineering, Fujian Agricultural and Forestry University Fujian Fuzhou,350002,China) Abstracts： Study on the processing the long bamboo-wood composite materials using method of the cold-hot-cold press. The experiment uses five symmetries balanced groups craft that uses the bamboo integration as the table board ,the wooden veneer stacking as the order in the board and the bamboo filament integration as the among core level. Necessary reequips the cold - hot – cold press unit, takes the continual long lumber with the batch process hot press; After using the orthogonal testing method and the FU rubber, thick board, 17mm, obtains the good craft of the hot pressing temperature 120℃, unit pressure 2.4MPa, hot pressing time 16min（using the Steam-impacting press can greagly shorten the hot pressing time on 11min）spreading the rubber to measure 240g/M2.Achieves the experimental anticipated advanced target.
