Abstract

The invention discloses a preparation method of modified sericite powder. The preparation method comprises the following steps: S1, adding lauryl polyoxyethylene ether, ethoxylated fatty acid methyl ester and sodium dodecylbenzene sulfonate into water; stirring and dissolving; carrying out ultrasonic de-foaming; then adding a silane coupling agent in sequence and stirring and dissolving to obtainan organic modified solution; S2, adding sericite powder into the organic modified solution and heating and stirring; vibrating and carrying out ultrasonic treatment; cooling to room temperature to obtain a sericite powder mixed solution; S3, centrifuging the sericite powder mixed solution at a high speed and removing supernatant; flatly laying sediment on a utensil and drying in vacuum to obtaina modified sericite dried cake; S4, grinding the modified sericite dried cake, carrying out the ultrasonic treatment, sieving and sub-packaging to obtain the modified sericite powder. The preparationmethod disclosed by the invention is simple to operate and high in recurrence rate; the prepared sericite powder has small granularity, large surface area, good wetting and dispersion effects and a wide application range.

Description

technical field [0001] The invention relates to the technical field of sericite preparation, in particular to a preparation method of modified sericite powder. Background technique [0002] Sericite, the most commonly used type of mica, is a silicate mineral with a layered structure and is widely used in rubber, plastics, coatings, paints, ceramics, thermal insulation, cosmetics, pigments, papermaking, metallurgy and other industries. The traditional sericite structure consists of two layers of silicon-oxygen tetrahedron sandwiching a layer of aluminum-oxygen octahedron compound silicon-oxygen layer. Complete cleavage, can be split into very thin flakes, the thickness of the flakes can reach less than 1u, and the ratio of diameter to thickness is large. However, the sericite powder prepared by the traditional preparation method is hydrophilic, so when used in resins, organic reagents and other media, the dispersibility is poor, and the phenomenon of agglomeration often occu...
