[0037] (1) Modification:

[0038] First, the dry modification of magnesium hydroxide, using γ-mercaptopropyltrimethoxysilane / magnesium stearate to carry out compound modification on magnesium hydroxide, adding magnesium hydroxide and magnesium stearate to a heatable high-sp...

Embodiment 1

[0049] Modification: First, dry modification of magnesium hydroxide, using γ-mercaptopropyltrimethoxysilane / magnesium stearate to carry out composite modification to magnesium hydroxide, adding magnesium hydroxide and magnesium stearate to the available Stir in a heated high-speed mixing mixer, set the temperature to 45°C, first stir at a stirring speed of 200r / min for 1min, then stir at a stirring speed of 500r / min for 4min; after the stirring is completed, add γ-mercaptopropyltrimethoxysilane , Stir at a stirring speed of 100r / min for 1min, then stir at a stirring speed of 400r / min for 6min, then stir at a stirring speed of 100r / min for 2min, then take it out after natural cooling, grind and refine it through 300 mesh or 300 mesh Screening through a sieve with the above pore size finally obtains γ-mercaptopropyltrimethoxysilane / magnesium stearate composite modified magnesium hydroxide. Secondly, the surface of nano-zinc oxide particles is modified, using ethanol or ethanol-w...
