Abstract

The invention discloses high-suspension mineral gel with low heavy metal and cristobalite. The mineral gel is prepared from, by weight, 100 parts of clay mineral, 2-8 parts of inorganic base and 0.5-2parts of sodium citrate and sodium pyrophosphate, wherein the clay mineral is selected from one or more of attapulgite clay, bentonite, sepiolite, halloysite and montmorillonite clay. The preparationmethod includes steps: grinding the clay mineral, adding inorganic base aqueous solution, mixing and extruding into sheets; covering with a film, keeping moisture to pile up for more than 10 days, adding water, and beating into emulsion; dewatering after filtering through a vibrating screen, adding water and diluted acid into a cake material to adjust pH to 3-4, and ultrasonically dispersing; adding a mixture of sodium citrate and sodium pyrophosphate, ultrasonically dispersing, adding water and alkali to adjust pH to 7-8, dewatering, drying and grinding to obtain the high-suspension mineralgel. By cristobalite removal, heavy metal removal and electric charge regulation for gel preparation in sequence, the high-suspension mineral gel is applicable to fields of medicines, food, daily chemicals and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of inorganic gel, in particular to a high-suspension mineral gel and a preparation method thereof. Background technique [0002] Mineral gels are widely used in pesticides, medicines, coatings, chemicals and other fields, mainly to stabilize, disperse, suspend, thicken, etc.; it is a one-dimensional nanomaterial processed from natural minerals, such as bentonite, which can be dispersed in water. A thixotropic gel is formed. [0003] At present, the preparation technology of natural bentonite processing inorganic gel is mainly wet pulping, sodium modification, separation and purification, drying and crushing to obtain products. [0004] CN1363515A discloses a preparation method of natural magnesium aluminum silicate gel, which uses bentonite, smectite, attapulgite or bentonite as raw materials, and proceeds according to the following steps: 1. Pulverize the raw materials; 2. Add water to the m...
