透气保水喷膜材料研究

Membrane-spraying material with the function of ventilation and water retention

提出了一种用于荒漠化地区固沙植草的新材料技术。以OP-10、吐温20和吐温80为乳化剂对可完全降解的废弃植物油乳化,然后对取自荒漠化地区流沙下层的细土质憎水改性,最后配以草籽,混合均匀制成土质憎水改性固沙植草材料。通过对该材料进行水分蒸发测试、模拟植草试验、显微分析、热分析和孔径-孔容分析,结果表明该材料具有透气保水功能,在人工气候箱中模拟植草试验效果明显,其最佳配方:乳化液与分散剂体积比为1:20,乳化液与土质颗粒比3:20(mL/g)。

This paper developed a new type technique of material which was used to plant grass and stabilize sands in desertification region.Take the OP-10,Vomit 20 and Vomit 80 to emulsify the discard vegetable oil,which can decompose completely,then carry on a hydrophobicity-modification towards the native soil from desertification region,in the end,mix with the grass seed for making into a stabilizing sands and planting grass material based on hydrophobicity-modified soil particles.According to the analyse of humidity evaporation,planting grass in the synthetic climate box,microstructure,thermoanalysis,aperture-aperture capacity to that material,the results show it has the function of ventilation and water retention and also performs well in the test of planting grass in the synthetic climate box which can imitate surroundings of the desert.The best proportion is that the hydrophobic component is 1：20（v/v） to water and 3：20（mL/g） to soil.
