摘要

【目的】用沙柳材的多元醇液化产物(LP)制备生物质聚氨酯硬质泡沫材料(LP-PU)。【方法】将纳米有机蒙脱土(OMMT)与沙柳材的多元醇液化产物(LP)在超声波震荡条件下均匀混合,然后将混合物(LP-OMMT)和异氰酸酯(PAPI)混合发泡。通过傅里叶红外光谱仪(FTIR)、X射线衍射仪(XRD)、透射电镜(TEM)和热重分析仪(TG)对泡沫材料的结构和性能进行表征和测试。【结果】在超声波振荡条件下,FTIR图谱表明加入OMMT使泡沫材料结构中的氢键指数增大,内聚能增大; XRD图和TEM照片显示OMMT在泡沫材料中层间距增大达到5.5 nm,出现插层态或剥离态; 材料的TG曲线向高温方向移动,残炭率为38.51%,热稳定性提高; 材料密度比纯液化产物聚氨酯泡沫材料降低了34.9%,但压缩强度基本不变; 泡沫材料的氧指数升高到37.2%,阻燃性能增强。【结论】加入适量的OMMT能够以插层和剥离态分散在泡沫材料中,并显著提高材料的力学性能、热稳定性和阻燃性能。

Abstract

【Objective】Foam biomass polyurethane rigid foam(LP-PU)by liquefaction products of salix(LP).【Method】Mix the organic montmorillonite(OMMT)and liquefaction products of salix(LP)under the condition of ultrasonic wave concussion and subsequently put the mixture(LP-OMMT)and isocyanate together to foam. The structure and property of obtained foam were characterized and tested by means of FTIR, XRD, TEM and TG. 【Result】The experimental results indicated that, under ultrasonic wave concussion, the FTIR shows that the addition of OMMT had increased the hydrogen bond index and cohesive energy of foam. It was observed from XRD and TEM images that the layer spacing of OMMT was 5.5 nm and it was more easily to disperse in the form of intercalation and the form of exfoliation. The TG curve of the materials moved to higher temperature and the carbon yield of foam was 38.51%. Therefore, the thermostability value increased. Moreover, the density of foam was 34.9% less than pure foam, while the compression strength almost remained unchanged. The flame retardant property reinforced, as the oxygen index of foam increased to 37.2%.【Conclusion】Intercalated or exfoliated OMMT can be prepared by adding just the right amount, which significantly improved themechanical properties, thermal stability and flame retardance of materials.
