Easily fall off.
(4) material that step (3) obtains is put into vacuum drying chamber and dries 6~8h, obtain modified magnesium hydroxide.
Preferably, heating-up temperature is 50~60 DEG C in the step (2).
Preferably, heating-up temperature is 75~80 DEG C in the step (3).
A kind of preparation method of Flame Retardant Powder Coatings comprises the following steps：
(A) by the Diglycidyl M-phthalate of formulation weight part, barium sulfate, dodecanedioic acid, styrax, isophthalic two
Phenol, polyacrylate, benzophenone, modified magnesium hydroxide, which are added in batch mixer, to be sufficiently mixed uniformly；
(B) batch mixing after being well mixed, which is added in screw extruder, to carry out melting extrusion, tabletting, crushes；
(C) material in step (B) is sent into pulverizer and crushed, obtain powdery paints.
Preferably, each area's temperature of screw extruder is respectively in the step (B)：One area's temperature：100~110 DEG C,
Two 120~130 DEG C of area's temperature, three 140~145 DEG C of area's temperature.
Therefore, the present invention has the advantages that：(1) powdery paints has preferable ultraviolet resistance, anti-aging
Performance；(2) Ractopamine has higher activity, and the magnesium hydroxide with being alkylated treated crosslinks reaction, makes hydrogen-oxygen
The attraction changed between magnesium declines, and reduces the attraction between magnesium hydroxide, magnesium hydroxide is uniformly blended in component, carry
Its high fire resistance；(3) carboxyl chitosan and the Ractopamine on magnesium hydroxide surface crosslink, and cover magnesium hydroxide surface
One layer of carboxyl chitosan of lid, so as to further improve the dispersive property of magnesium hydroxide；(4) carboxyl chitosan has more reaction
Group, such as amino, carboxyl, hydroxyl, it can crosslink reaction with other components in powdery paints, be favorably improved coating
Fire resistance；(5) magnesium hydroxide is by modified, and one layer of chitosan of its outer cladding, when running into external force, clad is to high polymer
Stress transmission is formed between aluminium hydroxide, the toughness of coating is improved by absorbing external force, prevents shock of the coating in external force
Easily fall off down.
