By the performance data of table 1 as it can be seen that embodiment 14 has replaced the size of nano silver into embodiment 24, analysis data can
Know that antistatic performance is best when the size of nano silver is in 40-45nm.
The test data in above-mentioned table 1 is analyzed, the sample using uncoated reflection film base material as control sample, in embodiment
Product have been coated with the coating fluid containing nano-Ag particles, and surface impedance performance is substantially reduced.Meanwhile there is no reduce for reflectivity.
Wherein, the comprehensive performance for the antistatic reflectance coating that embodiment 7-12 and embodiment 14-24 is provided is more preferable.Particularly, embodiment
The comprehensive performance for the antistatic reflectance coating that 16-18 is provided is best.
Particularly, 3% nano-Ag particles are added, the nano-Ag particles particle size is 40nm, while using molten
Dosage form heat cure acrylic resin prepares coating fluid, and on the reflecting film by coating fluid coating, antistatic effect is best,
The antistatic property for the antistatic reflectance coating that the embodiment of the present invention 18 provides is best.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.It is all
The equivalent changes and modifications that content is done according to the present invention are encompassed by the scope of the patents of the invention.
