Embodiment Construction
[0076] A nano-coating, nano-composite slurry made of nano-silica, nano-titanium dioxide and nano-calcium carbonate water slurry and composite additives, and then adding fillers and various additives, mixing reaction, shearing emulsification, sanding in a reactor The nano-coating is prepared by machine grinding and dispersing, mixing in the paint kettle and filtering by the filter. The nano-powder formed by coating in the nano-coating has a particle size of 30-40 nanometers and an average particle size of 35 nanometers. It has a closed surface The surface microstructure of the end and lotus leaf, the shape of the nano powder is spherical, with a tap density of 0.15-0.5g / cm, 125-180m 2 / g specific surface area, the nano coating is composed of the following material components by weight percentage:
[0077] Deionized water 3.8%
[0078] Nano composite pulp 11%
[0079] Ethylene glycol 2.7%
[0080] Hydroxyethyl cellulose (concentration 2%) 5.5%
[0081] Film forming aid (commercially...
