The invention relates to the technical field of electrochemical synthesis, in particular to a modified magnesium hydroxide, a flame retardant and preparation and application thereof. After filtering and drying to obtain modified magnesium hydroxide. This scheme has the following characteristics: 1) Controlling the flake shape of small particle size Mg(OH) 2 by adding Li + and suitable PH, current intensity and other process control; 2) By introducing cationic modifiers in the preparation of Mg (OH) 2 completes hydrophobic modification at the same time, improves the compatibility with polymer substrates, and greatly improves the anti-agglomeration performance; 3) Mg(OH) 2 has better dispersibility and achieves better results in the flame retardant performance test. 4) The brine after potassium extraction from the salt lake is used as the magnesium source, which effectively solves the problem of "magnesium damage". The source of raw materials is extensive and the cost is low, which opens up a new way of brine utilization and by-products can be utilized as resources. |
