Is the data wires usb 3 or is there another product for usb3 that does this?

This device does NOT pass the USB 3.x data lines, only the D+/D- used for USB 1 and USB 2. I do not know of a device which passes USB 3.x data lines only. Doesn't mean that it doesn't exist, but I have never seen one - ever.

Would this help on a usb keyboard(aluminum) when I walk around house electrostatic discharge when I touch it kb has to plugged in ?

No, this blocks power output from the USB port. As USB keyboards are powered by this voltage output, they keyboard wouldn't work unless it has an ac adapter, or used batteries to operate. The best use case I have found for these power blockers is to keep the voltage from away from the mainboard in a 3d printer so it is able to fully power off when the power supply is switched off.
