AI Technical Summary
In the existing technology, magnesium hydroxide prepared from brucite has problems such as low purity, uncontrollable crystal form, and uneven particle size distribution, making it difficult to simultaneously improve flame retardancy and processing performance.
By controlling the hydrothermal reaction time and temperature, the material ratio of the reaction system, and other conditions, the morphology and particle size of the crystals were regulated. Using pH adjusters and dispersants, micron-sized hexagonal flake magnesium hydroxide with regular morphology and uniform particle size was prepared.
Obtaining micron-sized hexagonal flake magnesium hydroxide with high purity, regular morphology, and uniform particle size significantly improves its performance as a flame retardant and smoke suppressant, especially in its application in EVA materials.
