Abstract

PURPOSE:To enable easy electroless plating on inorg. fine powder by sticking a silane coupling agent to the surface of the powder, sensitizing and activating the powder and carrying out electroless plating. CONSTITUTION:A water soluble silane coupling agent such as aluminosilane is stuck to the surface of inorg. fine powder such as fine Al2O3 powder or glass fibers and the powder is sensitized and activated. Electroless nickel plating is then carried out. By this method, uniform nickel plating causing no stripping can be stably formed on the surface of the inorg. fine powder.

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to inorganic fine powder used in various industries, more specifically, inorganic fine powder having a diameter of 1,000 am to several mm. This invention relates to an electrolytic nickel plating method.

Conventionally, when electroless nickel plating is applied to inorganic fine powder, palladium, which acts as a catalyst to deposit nickel, does not firmly adhere to the surface of the inorganic fine powder even if sensitizing/activation is performed after thoroughly washing the inorganic fine powder. Therefore, even if nickel plating was applied on top of it, the plating would peel off, and palladium itself would not adhere. Therefore, electroless nickel plating has been performed under severe processing conditions, such as increasing the temperature of the processing solution.

[Example 1] 10 g of glass fiber with a diameter of 7 μm and a length of approximately 50 μm
After putting it into 50 ml of ethyl alcohol and applying ultrasonic waves for 5 minutes, an aqueous potassium hydroxide solution was further added to thoroughly wash the gel sphere. Then, the glass fibers are separated by suction filtration, washed with pure water, and then washed at 0.00%.
After dispersing the 5 wt% aminosilane aqueous solution by applying ultrasonic waves for 5 minutes, the glass fibers were separated and purified again by suction filtration, and then baked in a constant temperature bath at 100°C for 30 minutes, followed by sensitizing and activating. Plating was done. At this time, each processing solution for sensitizing, activating, and nickel plating should be kept at 45°C or higher.
Although the test was carried out at a relatively low temperature of 50°C, the surface of the glass fiber was uniformly plated with nickel, and no peeling spots were found.
