Sodied sepiolite clay

Abstract

The invention discloses sodium modified sepiolite clay. The key points of the technical scheme are as follows: the sodium modified sepiolite clay is prepared from the following raw materials: sepiolite clay, magnesium oxide, sodium carbonate, instant sodium silicate, polyvinyl alcohol and hydroxypropyl methyl cellulose; the sodium modified sepiolite clay is prepared by virtue of following the steps: inputting the raw materials of the sodium modified sepiolite clay into a mill and grinding the raw materials into powder, wherein the grinded powder is the sodium modified sepiolite clay. The sepiolite clay is firstly modified by sodium and then the raw materials are compound, so that the sodium carbonate is prevented from reacting with the instant sodium silicate, polyvinyl alcohol and hydroxypropyl methyl cellulose; the sodium modified sepiolite clay can improve properties of the sepiolite clay, such as adsorbability, rheological property, heat stability, plasticity, caking property, catalysis, specific surface area, porosity and the like; the sodium modified sepiolite clay has good rheological property, thus becoming a valuable thickener, a suspending agent and a thixotropic agent, and being applicable to industries such as cosmetics, toothpaste, soap, paint, coating, fire protection and the like.

Description

technical field [0001] The invention relates to sodium treatment, in particular to a sodium-treated sepiolite clay. Background technique [0002] Sepiolite clay is a kind of clay with sepiolite as the main component, accompanied by attapulgite, montmorillonite, talc, etc., and non-clay minerals mixed with quartz, calcite, lapis lazuli, etc. [0003] In the sepiolite clay mining area, excavators are used to mechanize raw sepiolite clay ore, and what is excavated is a dense block of sepiolite clay raw ore. The raw sepiolite clay ore is relatively large and cannot be directly used for sodium treatment. For processing, most of them are crushed into fine particles by pulverizers, which can easily destroy the crystal structure of sepiolite clay. [0004] The quality of sepiolite clay products cannot be fully improved without subsequent auxiliary modification treatment after sodium treatment. Contents of the invention [0005] The purpose of the present invention is to overcome...

[0003] In the sepiolite clay mining area, excavators are used to mechanize raw sepiolite clay ore, and what is excavated is a dense block of sepiolite clay raw ore. The raw sepiolite clay ore is relatively large and cannot be directly used for sodium treatment. For processing, most of them are crushed into fine particles by pulverizers, which can easily destroy the crystal structure of sepiolite clay

[0004] After the sodium treatment, there is no subsequent auxiliary modification treatment, which cannot fully improve the quality of sepiolite clay products
