Abstract

Paper mulching films are affected by wind and rain in the field, which lead to the problems of water absorption, shrinkage, and friction with the soil surface. In order to achieve better hydrophobic durability and wear resistance of paper mulching films, a paper mulching film with ZnO/SiO2 composite coating was prepared by the brush coating method. Taking ceramic balls as friction pairs, reciprocating friction tests were carried out with two kinds of paper mulching films at different temperatures. The morphology of the raw paper mulch film and the ZnO/SiO2 composite-coated paper mulch film after rubbing at different temperatures and the reason of the hydrophobic durability of the coated paper mulch film were analyzed using a scanning electron microscope and a three-dimensional topography instrument. The results show that ZnO/SiO2 composite coating can improve the wear resistance and hydrophobic durability of the paper mulch film. Through surface morphology analysis, it can be found that the composite coating plays a role in modification and filling and improves the adhesion between the fibers by reducing the pores on the surface of the paper mulch film, finally improving the wear resistance and hydrophobic durability of the paper mulch film.

氧化锌/二氧化硅复合涂层纸地膜的摩擦和磨损特性研究
纸地膜在田间受到风雨的影响,会出现吸水、收缩以及与土壤表面摩擦等问题。为了使纸地膜具有更好的疏水耐久性和耐磨性,采用刷涂法制备了一种具有 ZnO/SiO2 复合涂层的纸地膜。以陶瓷球为摩擦副,在不同温度下对两种纸地膜进行了往复摩擦试验。使用扫描电子显微镜和三维形貌仪分析了原纸地膜和 ZnO/SiO2 复合涂层纸地膜在不同温度下摩擦后的形貌以及涂层纸地膜疏水耐久性的原因。结果表明,ZnO/SiO2 复合涂层能提高纸地膜的耐磨性和疏水耐久性。通过表面形貌分析可以发现,复合涂层起到了改性和填充的作用,并通过减少纸地膜表面的孔隙提高了纤维间的粘附力,最终提高了纸地膜的耐磨性和疏水耐久性。
