Embodiment 1-3
[0029] In the following examples 1-3:
[0030] Tin oxide antistatic gels are prepared according to the following preparation method:
[0031] Disperse tin oxide powder with a particle size of 0.5-2um into a water-soluble acrylic resin emulsion (acrylic resin content in the emulsion is 48-52wt%), the mass ratio of tin oxide powder to water-soluble acrylic resin emulsion is 1:4, 60°C Stir until a sol is formed, and then stand at 25°C to form a tin oxide antistatic gel;
[0032] Ultrafine alumina: particle size 100-300nm, white color, specific surface area > 50m 2 / g;
[0033] Ultrafine magnesium oxide: particle size 300-800nm, white color, specific surface area > 80m 2 / g;
[0034] Dendritic macromolecule quaternary ammonium salts are all prepared by grafting three-generation dendritic macromolecules with dodecane bromide or hexadecane bromide.
