【摘要】：本研究以木纖維、木粉、發(fā)泡劑、膠黏劑等為原料,采用微波成型工藝制備木纖維多孔緩沖材料,系統(tǒng)研究了材料配比對木纖維多孔緩沖材料特性的影響規(guī)律,獲得了優(yōu)化的材料配方。結(jié)果表明:采用正交試驗法優(yōu)選得出基于微波成型工藝的木纖維多孔緩沖材料最佳配方為木纖維用量6.8%,加水量61.8%,AC用量1.6%,木粉用量9.0%,由此配方制得試樣的密度為1.47×105 g·m-3,0.17 MPa應力所對應的緩沖系數(shù)為6.52,平均回彈率為75.6%。與傳統(tǒng)熱壓成型工藝相比,微波成型工藝可以降低98%以上的能耗,對工業(yè)化生產(chǎn)意義更大。
[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.
