Abstract
The present invention provides a kind of inkjet print heads, it includes having before polymer coating, the polymer coating includes oleophobic graft polymers, and the oleophobic graft polymers has the fluoroelastomer of crosslinking and is grafted to the perfluorinated fluorine-containing organic silicon of the fluoroelastomer of the crosslinking.The polymer coating has at least about 45 degree of ink contact angle and the ink slide angle less than about 35 degree.
Description
Technical field
Embodiment disclosed herein is related to the coating used on the element of printing equipment.Particularly, implementation disclosed herein
Example is related to the oleophobic moisture-resistant coating used on before print head.
Background technique
In typical solid ink print head construction, printer has the nozzle plate of injection array, and ink passes through
The injection array leaves injection heap.In some printhead systems, nozzle plate and injection heap include stainless steel plate, but recently this
A little parts have been replaced by flexible polymer skin such as polyimides.In some cases, polyimide film reception is bonded to stainless
The moisture-resistant coating of steel orifice plate, the array of subsequent laser ablated holes is into polyimide film.
The nozzle of ink leak, ink before the print head on wetting and attachment will lead to missing and injection direction mistake and
Bad picture quality.When the internal pressure of print head is more than specific pressure, the nozzle of ink leak will ooze out ink.Nozzle can be without exudation
The pressure that ground is kept is higher, and performance will be better.It will be soaked when keeping wet after printing before print head.It is maintained at
This ink on print head may block nozzle, so as to cause nozzle missing and Print direction mistake.Fig. 1 shows such quilt
Pollute the photo of print head.
A kind of method solved these problems uses active cleaning blade system.The system removes ink simultaneously from print head
And then wiping blade wipes ink from front.Ink is removed usually after system detection to injection missing and when ink has frozen
It is carried out after power-off when tying or solidifying, shrink and suck air into system.Ink, which is removed, will evict the air of pollutant, retention from
And nozzle clearing, then wiper cleans up front.
It is combined with wiping blade system, people improve performance using various moisture-resistant coatings.Although current coating
With it is good heat and ink stability, but mechanical robustness be likely lower than may expect, especially when with wiping blade system
Requirement when system is used in combination to these coatings.Other ask may occur because of the coating stability under print head manufacturing condition
Topic.
