Abstract：
 The invention discloses a substrate double-injection- hydrothermal modified method of high-dispersed magnesium hydroxide nanometer piece in the organic chemical technique domain, which is characterized by the following: adapting inorganic magnesium salt as raw material and inorganic alkaline as precipitant and inorganic chlorine salt as substrate solution; injecting the magnesium salt and inorganic chlorine salt solution at 10-80 deg.c; disposing the atmospheric product for 1-6 hours at 100-200 deg.c; improving the product structure through chlorine salt and hydrothermal environment to produce topographic regulation and good dispersion property magnesium hydroxide nanometer piece with 10-50nm even thickness, 30-300nm even diameter and 100 -600nm birdnesting particle size. The invention makes regular topographic, even grain size and good dispersing magnesium hydroxide nanometer piece, which is used in the plastic and rubber industry as high-property inorganic flame-proof brusque.
