Preparation method of high-strength wood composite inorganic particle board
The invention relates to a preparation method of a high-strength wood composite inorganic particle board and belongs to the technical field of artificial boards. The preparation method comprises the following steps: taking bamboo powder as the raw material to prepare nanocrystalline cellulose, carrying out joint melt intercalation on the nanocrystalline cellulose and ethylene-methylacrylic acid polymer into organic montmorillonoid to serve as reinforcing fillers of the particle board, and taking wood particulate, straw particulate and an inorganic adhesive as the raw materials to prepare the high-strength wood composite inorganic particle board through the hot-pressing technology. According to the preparation method, the organic montmorillonoid is provided with silicate layers, joint meltintercalation is carried out on the nanocrystalline cellulose and ethylene-methylacrylic acid polymer into organic montmorillonoid, the layered silicate amounts to a physical crosslinking point in thepolymer matrix, and the physical crosslinking point and the particulates are nailed and anchored, so that when a system receives external force, the physical crosslinking point is damaged to absorb energy so as to improve the impact property and the bending property of the material.
本发明涉及一种高强度木材复合无机碎料板的制备方法，属于人造板技术领域。本发明以竹粉为原料制备一种纳米微晶纤维素，将纳米微晶纤维素和乙烯‑甲基丙烯酸共聚物共同熔融插层至有机蒙脱土中作为碎料板的增强填料，以木材碎料、秸秆碎料和无机胶黏剂为原料，通过热压工艺制备出一种高强度木材复合无机碎料板，本发明中有机蒙脱土拥有硅酸盐片层，将纳米微晶纤维素和乙烯‑甲基丙烯酸共聚物共同熔融插层至有机蒙脱土中，层状硅酸盐在聚合物基体中相当于“物理交联点”，该“物理交联点”与碎料“钉锚”在一起，因此，当体系受到外力作用时，这些“物理交联点”受到破坏，吸收能量，使材料的冲击性能和弯曲性能得到改善。
