Problems solved by technology

[0005] However, due to the high surface energy of the nano-powder, if a certain dispersant is not added during the dispersion process of the nano-powder, the powder will be difficult to disperse or agglomerate after dispersion, so the dispersion system is difficult to stabilize

Embodiment 1

[0026] Add 90ml of deionized water to a 300ml ball mill tank, then add 0.05g of triethanolamine, stir well and add 10g of ATO powder; stir again, then add ammonia water and hydrochloric acid, adjust the pH value to 9.03; then add 50ml of zirconium beads, ball mill After 48 hours, the ball mill jar was removed, the slurry was poured out, and the zirconium beads were filtered off to obtain a nano-ATO stable aqueous slurry with an average particle size of 102 nm and a pH value of 7.58. The slurry was stored for 5 months without visible precipitation.

Embodiment 2

[0028] Add 90ml of deionized water to a 300ml ball mill jar, then add 0.1g of triethanolamine, stir well and then add 10g of ATO powder; stir again, then add ammonia water and hydrochloric acid to adjust the pH value to 9.05; then add 50ml of zirconium beads, ball mill After 48 hours, the ball mill jar was removed, the slurry was poured out, and the zirconium beads were filtered off to obtain a nano-ATO-stabilized aqueous slurry with an average particle size of 86.6 nm and a pH value of 7.5. The slurry was stored for 5 months without visible precipitation.

Embodiment 3

[0030] Add 90ml of deionized water into a 300ml ball mill jar, then add 0.2g of triethanolamine and 0.2g of PVA1750 (polyvinyl alcohol), stir well and add 10g of ATO powder; stir well again, then add ammonia water and hydrochloric acid, and adjust the pH value to 9.0; add 50ml of zirconium beads, mill for 48 hours, remove the ball mill jar, pour out the slurry, and filter out the zirconium beads to obtain a nano-ATO stable aqueous slurry with an average particle size of 100nm and a pH value of 8.22. The slurry was stored for 5 months without visible precipitation.

Abstract

A nano Sb doped water SnO2 slurry for antistatic or antiradiation coated layer is prepared through dispersing the nano ATO powder in water, adding disperser and pH regulator, and blal grinding. It has long storage period (more than 5 months).

Description

technical field [0001] The invention relates to a tin dioxide aqueous slurry doped with nano antimony and a preparation method thereof. Background technique [0002] In recent years, with the development of material science and technology, various polymer materials such as plastics, fibers, rubber, coatings, etc. have increasingly entered various fields of society. For example, the shells and surfaces of most electronic instruments, aerospace vehicles, and household appliances are It is processed from these polymer materials. Due to the insulating properties of polymer materials, static electricity is easily generated and accumulated when the surface is rubbed or impacted. When the static electricity accumulates to a certain extent, electrostatic discharge will occur and lead to vicious events. With the continuous improvement of people's living standards, various display devices have entered more and more families. These display devices have strong radiation to the human bo...
