Mud rock hydrophobic modification method
The invention provides a mudstone hydrophobic modification method, and relates to the technical field of geotechnical engineering. The mudstone hydrophobic modification method provided by the invention comprises the following steps: heating mudstone to obtain modified mudstone; the heating temperature is 140 to 340 DEG C; the heating time is 10 to 60 minutes. According to the invention, within a certain heating temperature range, each mineral component in the mudstone is not thermally decomposed within the temperature range, so that thermal damage to the mudstone is avoided; the mineral particles are heated to expand, so that mudstone pores are filled with water, infiltration channels are reduced, and the hydrophobicity of the mudstone surface is further improved; the moisture of the mudstone is evaporated at high temperature, so that the lubricating effect among particles is weakened, the friction force is increased, and the mechanical property of the mudstone is enhanced. The mudstone is modified by adopting a heating method, so that the method is economical, non-toxic and suitable for popularization and application.
本发明提供了一种泥岩疏水改性方法，涉及岩土工程技术领域。本发明提供的泥岩疏水改性方法，包括以下步骤：将泥岩进行加热，得到改性泥岩；所述加热的温度为140～340℃；所述加热的时间为10～60min。本发明在一定的加热温度范围内，泥岩中各矿物组分在该温度范围内并没有发生热分解，不会对泥岩造成热损伤；矿物颗粒受热膨胀，导致泥岩孔隙被填充水分入渗通道减少，进而进一步的提高泥岩表面的疏水性；泥岩在高温下水分蒸发，导致颗粒间的润滑作用减弱，摩擦力增大，从而导致泥岩的力学性能得到强化。本发明采用加热的方法对泥岩进行改性，经济、无毒，适宜推广应用。
