Problems solved by technology

[0004] At present, almost all photosensitive drum coatings are solvent-based coatings. Organic solvents are used as the main solvent of coating materials. They are all volatilized during the baking and film forming process and discharged into the atmosphere, causing serious VOC emission pollution.
On the other hand, organic solvents are generally flammable, explosive, and toxic, and there are serious safety hazards and harm to human health during transportation, storage, and use.

Embodiment 1

[0016] A solvent-free photoelectric semiconductor coating formulation, which is composed of: monofunctional acryloylmorpholine: 40 parts, difunctional acrylate CD406: 10 parts, difunctional acrylate SR480 NS: 20 parts, nine-functional urethane acrylate CN9013 NS : 10 parts; photoinitiator (TPO-L): 5 parts; titanium phthalocyanine: 5 parts; hole transport material: 30 parts, electron transport material: 10 parts; leveling agent BYK333: 0.5 parts;

[0017] The hole-transporting material uses aniline derivatives containing methoxy or acrylic acid.

[0018] The electron transport material uses carbazole compounds.

[0019] After the above materials are mixed and dissolved completely, grind on a grinder for 2 hours, 1mm zirconium beads, 80% chamber filling. The resulting liquid was filtered through a 5 micron filter. Use the ring coating method to coat a layer of coating film on the aluminum substrate. Under the following UV ultraviolet light conditions, rotate the light to obtai...
