Problems solved by technology

However, the artificial synthesis methods of these foreign companies have many fatal flaws: not only the production process is complicated, the production efficiency is low, but also the washing process needs to consume a lot of water resources, especially the production safety risk is high (because of the high water temperature)

Abstract

The invention discloses a solid-phase synthesis method of nano magnesium aluminosilicate for a waterborne rheological auxiliary agent. The solid-phase synthesis method is characterized by taking cheapchemical raw materials including sodium silicate, aluminum salt, magnesium salt and the like as starting reaction materials and comprising the following steps: firstly, generating precursor gel underan alkaline condition; then carrying out roasting treatment to prepare the nano magnesium aluminosilicate with excellent thickening performance. The nano magnesium aluminosilicate can be used as thewaterborne rheological auxiliary agent and is widely applied to waterborne system industries including cosmetics, medicines, foods and the like.

Description

technical field [0001] The invention relates to the field of synthesis of smectite group minerals, in particular to a solid-phase synthesis method of nano-magnesium aluminum silicate with high thixotropy, high thickening ability and high viscosity. Background technique [0002] Bentonite is a non-metallic mineral with Montmorillonite as the main mineral component, and the scientific name of Montmorillonite is magnesium aluminum silicate. Although bentonite resources are very rich in nature, due to the large number of associated non-clay minerals (mainly quartz, white feldspar, calcite, etc.), the high-purity montmorillonite concentrate obtained by existing extraction and refining technology is still not suitable. Pure magnesium aluminum silicate, but a mixture of magnesium aluminum silicate and a small amount of impurities. In fact, due to differences in ore-forming geological conditions (for example, during the mine maturation process, different positions of the ore bodi...
