The front view of Tohesodo, Figure 4 is an enlarged sectional view, and in the figure,
2 is a resin head, 2 is a water-repellent member, and 3 is a nozzle hole.As shown in the figure, a water-repellent H1 (material 2) is provided on the surface of the nozzle hole 3.By the way, the resin that is the head member is The surface resistance value is very large at 1015 to 101SΩ, and it is easy to charge and difficult to discharge.In addition, fluorine, which is a water-repellent material,
Fat is also easily charged. Therefore, dust is likely to adhere to the nozzle side surface due to the electrical charge, and there is a possibility that the nozzle hole may be blocked.

値は高いままなので、帯電防止効果が半減してしまう。Therefore, it is necessary to perform antistatic treatment on the nozzle side surface. By the way, antistatic treatment generally lowers the surface resistance of a solid and promotes electrical discharge, but if a surfactant is used for this purpose, the solid surface becomes hydrophilic and water repellency is required. It is not suitable for use as a nozzle surface for inkjet printing. Further, when a metal is attached to the surface, the solid surface has the physical properties of the metal. Therefore, as shown in FIG. 6, when the antistatic 1L agent 6 is attached from one side of the water repellent member 2 provided on the resin head 1, the water repellent effect may be impaired. On the other hand, as shown in Figure 7, the surface of the resin spatula 1 river is treated with anti-static treatment,
If a water repellent treatment is applied thereto, the surface resistance value of the water repellent member 2 remains high, and the antistatic effect is halved.

Cellulose cannot be said to be a hydrophobic film with excellent ink resistance;
When a fluororesin with good ink resistance is used, the antistatic effect is halved and the fixing properties are also poor.

411 Antistatic treatment is performed on the nozzle side surface of the oil-based ink jet head without reducing its water repellency to 10%, preventing dust from adhering to the nozzle fill surface and reducing the effect on the ink droplet ejection direction. The object of the present invention is to provide an inkjet inkjet 1-head.

Hereinafter, the present invention will be explained based on examples.

るようにしたものである。First, as shown in Figure 7 above, even if the resin surface is subjected to antistatic treatment and water repellent treatment is applied to -L, the antistatic layer is sufficiently grounded and the thickness of the water repellent material is reduced. If it is made thin enough, the charge will move in the thickness direction of the water-repellent material and will be discharged.
When the outermost layer is an antistatic layer, a considerable antistatic effect is expected, even if it is inferior. At that time, if the antistatic agent is simply applied, the bond between the water repellent member and the resin substrate and the antistatic agent is weak (adhesion becomes a problem. Therefore, in the present invention, the antistatic agent is effective as a 1F antistatic agent. A certain conductive filler is added to the water-repellent member or resin substrate to strengthen the bond between the antistatic agent and the water-repellent member or resin substrate, and a coupling agent is further applied between the water-repellent member and the resin substrate. In addition to increasing the adhesion between the two, the conductive filler is grounded.

is ABS resin! 111J, the water repellent member 11 is made of a fluorine-based water repellent, and 20 to 40 wt % of fine metal powder, such as A1 or Ni, is added and dispersed therein. This metal filler 1
After applying the water repellent agent 2, water repellent 2 concentrates on the substrate side due to the action of gravity. At this time, since the metal filler is an inorganic substance, the adhesiveness between the substrate and the water repellent member is poor if left as is. Therefore,
As a pretreatment for water repellent treatment, a camping agent 14 such as a silane coupling agent is coated on the resin substrate. At this time,
The functional group of the silane coupling agent faces the resin substrate side and forms a strong bond with the substrate. On the other hand, the other side of the camping agent 14 exhibits a strong bond with the inorganic substance, ie, the metal filler.
これにより金属フィラーを混入した撥水部材は樹脂基板
と強い密着性を呈する。As a result, the water-repellent member containing the metal filler exhibits strong adhesion to the resin substrate.

損なうことはない。When a metal filler is mixed, the surface resistance value on that side is 10
16 to 10-'Ω, resulting in a strong antistatic effect. A portion of this metal filler should be grounded. Since the metal filler concentrates inside the water-repellent member under the action of gravity, the outermost surface is lined with fluorine groups and does not impair water repellency.

その際、樹脂基板表面は金属フィラーが並び、やはりこ
のままでは撥水部材との密着性が良くない。At this time, the surface of the resin substrate is lined with metal fillers, and if left as is, adhesion to the water-repellent member is not good.

性を良くすることができる。Effects - As is clear from the explanation below -1-, the present invention has advantages. If L is made of resin with water-repellent treatment applied to the nozzle hole surface, a conductive filler is added to the RAD water-repellent part +A or 461 resin substrate, so it is antistatic without reducing the water repellency by 10%. In addition, since the coupling agent is applied between the water repellent member and the resin substrate, the adhesion of the water tray member can be improved.
更に、撥水処理、帯電処理方法が簡単なのでヘソＩＳの
生産性を向上させることができる。Furthermore, since the water repellent treatment and charging treatment methods are simple, the productivity of the belly button IS can be improved.
