Sodiumized Imonite Mixed Layer Clay

Abstract

The invention discloses a sodium-modified illite-montmorillonite mixed-layer clay. The technical scheme is as follows: the sodium-modified illite-montmorillonite mixed-layer clay is composed of illite-montmorillonite mixed-layer clay, magnesia, sodium carbonate, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium acid pyrophosphate. The sodium-modified illite-montmorillonite mixed-layer clay materials are input into a mill and milled, and the milled powder illite-montmorillonite mixed-layer clay is the sodium-modified illite-montmorillonite mixed-layer clay. The sodium modification can enhance the water absorptivity, colloid index, expansion coefficient, colloid viscosity, cation exchange capacity, and dispersivity and suspension percentage in an aqueous medium of the illite-montmorillonite mixed-layer clay. The sodium-modified illite-montmorillonite mixed-layer clay has the characteristics of favorable thixotropy, favorable lubricating property, favorable heat stability, higher plasticity and higher binding property. The sodium-modified illite-montmorillonite mixed-layer clay is suitable for papermaking, cosmetics, plastics, rubber, paints, ceramics, textiles, cable insulation materials and firefighting materials.

Description

technical field [0001] The invention relates to sodium treatment, in particular to a sodium-treated imonite mixed-layer clay. Background technique [0002] If two or more clay mineral structural unit layers are regularly superimposed on each other, it is called an ordered mixed layer, otherwise it is called a disordered mixed layer, such as an illite mixed layer, a green smectite layer, and an iridescent mixed layer. [0003] Illite can be transformed into montmorillonite under certain conditions. During the conversion process, illite-smectite mixed-layer minerals, a transition mineral, are first formed. The existence of illite-smectite mixed-layer minerals will affect the mineral properties and process performance of illite, limiting its industrial application range. [0004] In the Yimeng mixed layer clay mining area, excavators are used for mechanized mining of Yimeng mixed layer clay ore. What is excavated is a dense block of Yimeng mixed layer clay ore. The volume of Y...

Problems solved by technology

[0005] After the sodium treatment, there is no subsequent auxiliary modification treatment, which cannot fully improve the quality of the mixed-layer clay products.

[0006] There is a large amount of mixed-layer clay in my country, especially in Shangsi County, Guangxi Zhuang Autonomous Region. Under the sugarcane field that can't be forgotten at a glance, there is mixed-layer clay with a depth of more than 100 meters, but there are very few of them. used in actual production
