Preparation method of oil shale semicoke-based recyclable mulching film
The invention discloses a preparation method of an oil shale semicoke-based recoverable mulching film, which is characterized in that oil shale semicoke is pretreated through acid etching and calcining processes, so that unstable variable-valence metal ions, organic matters and associated biomass such as carbonate and pyrite in the oil shale semicoke are effectively removed, and the specific surface area of the oil shale semicoke is increased; the subsequent reaction is facilitated; then a magnesium-aluminum hydrotalcite compound is generated on the surface of the pretreated oil shale semi-coke through a hydrothermal reaction method, so that the thermal stability and the cold resistance of the mulching film are enhanced; then a butylbenzene copolymer structure is introduced into the oil shale semicoke, and the butylbenzene copolymer can provide certain thermal isolation in the environment due to low thermal conductivity of the butylbenzene copolymer and reduce convection of heat, so that the mulching film is helped to keep a relatively stable temperature, and the influence of day and night temperature difference on plants is further relieved.
本发明公开了一种油页岩半焦基可回收地膜的制备方法，本发明通过酸蚀和煅烧的工艺对油页岩半焦进行预处理，有效去除了油页岩半焦中不稳定的变价金属离子、有机质以及碳酸盐、硫铁矿等伴生物质，增大了油页岩半焦的比表面积，利于后续反应的进行；然后通过水热反应的方法，在预处理油页岩半焦的表面生成镁铝类水滑石化合物，增强了地膜的热稳定性和耐寒性能；再将丁苯共聚物结构引入到油页岩半焦中，丁苯共聚物的低热导率使其能够在环境中提供一定的热隔离，减少热量的对流，从而帮助地膜保持相对稳定的温度，进一步减缓昼夜温差对植物所带来的影响。
