【摘要】：本研究以木纤维、木粉、发泡剂、胶黏剂等为原料,采用微波成型工艺制备木纤维多孔缓冲材料,系统研究了材料配比对木纤维多孔缓冲材料特性的影响规律,获得了优化的材料配方。结果表明:采用正交试验法优选得出基于微波成型工艺的木纤维多孔缓冲材料最佳配方为木纤维用量6.8%,加水量61.8%,AC用量1.6%,木粉用量9.0%,由此配方制得试样的密度为1.47×105 g·m-3,0.17 MPa应力所对应的缓冲系数为6.52,平均回弹率为75.6%。与传统热压成型工艺相比,微波成型工艺可以降低98%以上的能耗,对工业化生产意义更大。
[Abstract]:In this study, wood fiber, wood flour, foaming agent and adhesive were used as raw materials to prepare wood fiber porous buffer material by microwave molding technology. The effects of material ratio on the properties of wood fiber porous buffer material were systematically studied. The optimized material formula was obtained. The results showed that the optimum formula of wood fiber porous buffer material based on microwave molding technology was the amount of wood fiber 6.8, water content 61.8% AC 1.6, wood flour 9.0%. The results showed that the optimum formula of wood fiber porous buffer material based on microwave molding technology was as follows: the amount of wood fiber was 6.8, the amount of water added was 61.8 and the amount of AC was 1.6. The density of the sample prepared by the formula is 1.47 脳 105g m ~ (-3) m ~ (-3) MPa stress. The buffer coefficient corresponding to the stress is 6.52, and the average springback is 75.6%. Compared with the traditional hot pressing process, Microwave molding technology can reduce the energy consumption by more than 98%, which is more significant for industrial production.
