An artificial timer and preparing method thereof. The artificial timber includes the following components in parts by weight: 35-50 parts of cellulose, 20-35 parts of hemicellulose and 15-35 parts of lignin, wherein the artificial timber has a density of 0.01-0.05 g/cm3. The preparing method includes: (1) dissolving 15-35 parts by weight of lignin, 35-50 parts by weight of cellulose and 20-35 parts by weight of hemicellulose with an ionic liquid; (2) cleaning and replacing it with water to obtain a lignocellulose hydrogel; and (3) drying the lignocellulose hydrogel to obtain an artificial timber. The prepared artificial timber is large in specific area, low in density, low in material energy consumption, moderate in condition and easy for operation. The obtained artificial timber is regular in shape and shaped like a sandy beige cylinder without obvious damage and deformation, which indicates that such artificial timber with high specific area has well molding capacity.
一种人造木材及其制备方法。人造木材包括以下重量份数的组分:35-50 份纤维素、20-35 份半纤维素和 15-35 份木质素,其中人造木材的密度为 0.01-0.05 克/立方厘米。制备方法包括(1) 用离子液体溶解 15-35 份(重量)木质素、35-50 份(重量)纤维素和 20-35 份(重量)半纤维素;(2) 清洗并用水代替,得到木质纤维素水凝胶;(3) 干燥木质纤维素水凝胶,得到人造木材。制备的人造木材比面积大、密度小、材料能耗低、条件适中、易于操作。制得的人造木材形状规整,形似沙米色圆柱体,无明显损伤和变形,表明这种高比面积的人造木材具有良好的成型能力。
