Background
Magnesium hydroxide is a novel environment-friendly filling type flame retardant, releases bound water when heated and decomposed, absorbs a large amount of latent heat to reduce the surface temperature of a synthetic material filled with the magnesium hydroxide in flame, has the effects of inhibiting the decomposition of a polymer and cooling generated combustible gas, and magnesium oxide generated by decomposition is a good refractory material and can also help to improve the fire resistance of the synthetic material. Magnesium hydroxide is a well-known excellent flame retardant with triple functions of flame retardance, smoke suppression and filling in the rubber and plastic industry. However, magnesium hydroxide has poor dispersibility and compatibility in high polymer materials, and tends to cause the mechanical properties of flame retardant materials to be reduced. Therefore, how to increase the compatibility between magnesium hydroxide and polymer is a problem to be solved. It is first of all necessary to further explore the modification techniques for improving magnesium hydroxide. In the process of modifying magnesium hydroxide by the existing modification equipment, because different magnesium hydroxide powder particles have different sizes and are large in dispersion difference, after a modifier is added, the dispersion uniformity is poor, the agglomeration phenomenon is easy to generate, and the modification efficiency is often low.
