Hebei Messi Biology Co., Ltd. stated that whisker products are well used in rubber, plastic and other fields due to their high strength. However, the preparation of high-purity basic magnesium carbonate whiskers is not technically mature at present. In view of the deficiencies of the above-mentioned prior art, the present invention provides a preparation method of basic magnesium carbonate whiskers. Basic magnesium carbonate whiskers with uniform morphology that can be industrially produced can be obtained.
The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A preparation method of basic magnesium carbonate whiskers, characterized in that it comprises the following steps: mixing magnesium carbonate solution and ammonium acetate into deionized water, adding hydrogen peroxide to the mixed solution, pouring into a reactor for hydrothermal uniform precipitation reaction, the reaction time is 12-36h, and the reaction temperature is 180-230°C; and then filtering, washing and drying to obtain a basic magnesium carbonate whisker product.
The beneficial effect of the present invention is: preparing basic magnesium carbonate whiskers by hydrothermal reaction in one step, the method is simple and suitable for industrial production.
