中文摘要:木质陶瓷是一种功能性木质炭素新材料,残碳率是木质陶瓷的一个重要指标,论文试图选择合适的阻燃剂以提高木质陶瓷的残碳率。试验选取了麦秸、热固型酚醛树脂、酒精等为原料,氯化锌、碳酸钾、磷酸氢二氨以及硼砂等为阻燃剂,按照一定的比例混合均匀并热压成一定尺寸的坯体,再将坯体在氮气保护下按两种升温模式分别烧结至300℃、400℃、500℃、600℃、700℃和800℃,制备出各温度点下的木质陶瓷,观察分析了阻燃剂对其残碳率的影响。结果表明,与对照组比较,添加适量的阻燃剂后,在两种升温模式下,木质陶瓷的残碳率分别提高了大约6%和10%,而其抗弯强度、密度、显气孔率及电阻率等性能没有受到影响。结果证明了通过此工艺用麦秸制备木质陶瓷的可行性,同时表明了氯化锌、碳酸钾、磷酸氢二氨以及硼砂等阻燃剂对木质陶瓷残碳率提高的良好效果,试验结果也为麦秸的综合利用开辟了新的方向和空间。

Abstract:Woodceramics is a kind of new functionality wood charcoal material, the ratio of remaining carbon is an important parameter of woodceramics. This thesis tries to choose appropriate additives to increase the ratio of remaining carbon of woodceramics. Wheat straw, thermosetting resin, alcohol ,etc, were selected as raw materials and Zncl2, K2CO3, (NH4)2HPO4 and Na2B4O7·10H2O as additives. All these components were mixed uniformly according to the proportion and hot-pressed to sample with the dimension. The samples were put into the vacuum furnace and sintered in the atmosphere of nitrogen ,and the termination temperature was 300℃, 400℃, 500℃, 600℃, 700℃ and 800℃, respectively, and woodceramics were prepared and the effects of the additive on the ratio of remaining carbon were investigated. It showed that, compared with contrasting group, after adding proper additive , the ratio of remaining carbon of woodceramics increased about 6% and 10% separately under two heating models , while other properties such as bending strength, density, porosity and resistivity of woodceramics don’t change. The result testfies the feasibility of preparing woodceramics using wheat straw by that technique. At the same time, it indicates that the ratio of remaining carbon of woodceramics can be increased significantly. using ZnCl2, K2CO3, (NH4)2HPO4 or Na2B4O7·10H2O as additives. The presented work also pioneers a new aspect and space for recycling wheat straw synthetically.
