When the button is touched schedule an event (Clock.schedule_once()) that will disable the button in 5 seconds.  If the button is pressed cancel the scheduled event.

 

from kivy.app import App
from kivy.lang import Builder
from kivy.clock import Clock
from kivy.uix.button import Button

kv = """
BoxLayout:
    orientation: 'vertical'
    TimeButton:
        id: tb
        text: 'Press to disable 5 seconds after last touch'
        on_release: self.five_second_disable()
    Button:
        size_hint_y: None
        height: 48
        text: 'Reset'
        on_release: tb.disabled = False   
        
"""


class TimeButton(Button):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.schedule = None

    def five_second_disable(self):
        if self.schedule:
            self.schedule.cancel()
        self.schedule = Clock.schedule_once(self._disable, 5)

    def _disable(self, dt):
        self.disabled = True
        self.schedule = None


class TimeButtonApp(App):
    def build(self):
        return Builder.load_string(kv)

TimeButtonApp().run()
