Description
Technical Field
The utility model relates to the field of electrolytic copper foil production equipment, in particular to a silane coating device.
Background
The electrolytic copper foil is produced through the main technological steps of dissolving copper, producing foil, post-treating, cutting, packing, storing, roughening, curing, heat resisting, oxidation preventing, silane coating, etc. The silane coupling agent can be used for treating the surface of the copper foil to improve the physical property and corrosion resistance of the copper foil. The silane coupling agent can form a protective silicon oxide coating layer, and effectively prevents copper from contacting oxygen, moisture and other chemical substances in the environment, so that corrosion and oxidation of the copper surface are reduced. The M surface (rough surface) of the copper foil is treated in the silane coating link, so that the peeling strength and oxidation resistance of the copper foil can be improved, and the improvement effect depends on the concentration of silane liquid and the uniformity of the surface of the copper foil. When the concentration of the silane liquid in the post-treatment tank is reduced along with the consumption of the use, the oxidation resistance and the peeling resistance of the copper foil are affected, and when the concentration of the silane liquid is too high, an uneven covering layer is formed: too high a concentration of silane coupling agent may not be easily uniformly distributed on the surface of the copper foil during the coating process, resulting in formation of an uneven coating layer. This may lead to inconsistent surface protection, and some areas have poor protection and are susceptible to corrosion and oxidation. Stacking and caking occurred: the high concentration of the silane coupling agent may cause stacking and caking on the surface of the copper foil. These build-up and caking can lead to increased surface roughness and can form thicker overburden in some areas, affecting the flatness and surface quality of the copper foil. At the same time, the manner of spraying the silane also directly affects the coating effect, which also occurs when the spraying is uneven. Therefore, in the actual post-treatment link, the concentration of the silane liquid in the groove needs to be maintained relatively stable, and the reasonable spraying flow and mode are ensured, so that the silane liquid is uniformly coated on the rough surface of the copper foil.
Chinese patent publication No. CN203540800U describes a coupling agent spraying apparatus for spraying a coupling agent onto the roughened surface of an electronic copper foil. The spraying device for the coupling agent comprises a liquid supply tank for storing the coupling agent, a liquid supply pump, a filter, a heat exchanger, a valve, a silane spray pipe and a liquid return tank. The liquid supply tank is provided with an overflow port, and the liquid supply tank, the liquid supply pump, the filter, the heat exchanger, the valve, the silane spray pipe and the liquid return tank are connected end to end in sequence. The utility model enhances the spraying effect, solves the flow control problem, and enables the superfluous coupling agent after spraying to be recycled, thereby greatly saving the cost.
