Abstract

The invention discloses a nano silica sol with a novel structure to improve the main defects that existing silica sol is high in impurity content, low in silica concentration, poor in stability in an acid or neutral condition, short in service cycle, mixed in color, few in variety and the like and to solve the technical problems that the sizes of existing silica sol particles cannot be controlled, the morphologies cannot be controlled, the interface among the particles is not clear and the like. The nano silica sol has the characteristics of low cost, good heat resistance, solution resistance and barrier property, high mechanical strength, low impurity content, high silica concentration, good stability in the acid or neutral condition, single color and luster, long service cycle and the like.

Description

technical field [0001] The invention relates to a new material, in particular to a nano-silica sol with a new structure. Background technique [0002] Silica sol is a dispersion of silicon dioxide in water or other organic solvents, widely used in precision casting, refractory materials, coatings, textiles, precision polishing and other fields. Domestic silica sol production technologies mainly include ion exchange method and silica powder hydrolysis method. [0003] The production process of the silicon powder hydrolysis method is mainly to add water to the reaction kettle, add a basic catalyst, and after heating to a suitable temperature, add silicon powder, so that the silicon powder is hydrolyzed under alkali catalysis to generate silicic acid and polymerize into carbon dioxide. For silicon particles, the reaction lasts for a certain period of time. After the silicon powder basically reacts completely, the temperature of the reaction mixture is lowered, and finally filt...
