Bamboo-wood fiber board using bio-based non-formaldehyde adhesive and preparation method thereof
The invention discloses a bamboo-wood fiber board using bio-based non-formaldehyde adhesive and a preparation method thereof. The fiber board comprises the raw materials of, by weight, 60-70 parts offirst fiber, 6-10 parts of second fiber, 10-20 parts of adhesives, 25-35 parts of hydrophobic auxiliary agents, 6-8 parts of additives and 6-8 parts of modifiers. The second fiber is prepared from anhydrous aluminum chloride, aluminum powder, water, magnesium lactate and acetic acid, a sol-gel method is adopted during preparation, and the anhydrous aluminum chloride, the aluminum powder and the water are polymerized under a reaction condition to form a linear polymer to obtain polyaluminium chloride sol; and the magnesium lactate is added, the acetic acid is used as a stabilizer, and a spinning solution is obtained by stirring and reduced pressure distillation. According to the fiber board and the preparation method, the bamboo-wood fiber board is reasonable in component design and simplein process operation, the prepared bamboo-wood fiber board does not contain formaldehyde, benzene and xylene toxic substance release, formaldehyde pollution is effectively avoided, and the bamboo-woodfiber board has excellent mechanical property, high strength, excellent hydrophobic property and high practicability.
本发明公开了一种使用生物基无醛胶的竹木纤维板及其制备方法，所述纤维板各组分原料包括：以重量计，第一纤维60‑70份、第二纤维6‑10份、胶黏剂10‑20份、疏水助剂25‑35份、添加剂6‑8份、改性剂6‑8份。第二纤维由无水氯化铝、铝粉、水、乳酸镁、醋酸制备得到，在制备时采用溶胶‑凝胶法制备，先通过无水氯化铝、铝粉、水在反应条件下水解聚合形成线性聚合物，得到聚合氯化铝溶胶；再加入乳酸镁，并以醋酸为稳定剂，搅拌减压蒸馏得到纺丝液。本发明组分设计合理，工艺操作简单，制备得到的竹木纤维板中不含甲醛、苯、二甲苯类有毒物质释放，有效避免了甲醛污染，该竹木纤维板具有优异的力学性能，强度高，疏水性能优异，具有较高的实用性。
