Abstract

The invention discloses a production method of a light emitting coating layer. The production method comprises the following steps of fully mixing piezoelectric ceramic particles and electroluminescent powder to obtain piezoelectric mixed powder; applying a layer of conductive adhesive on a substrate to form a conductive coating layer; applying the piezoelectric mixed powder on the conductive coating layer to form a piezoelectric coating layer, wherein the thickness of the piezoelectric powder is controlled to be below 2 millimeters; applying a layer of the conductive adhesive on the piezoelectric coating layer again to obtain the light emitting coating layer. Through the above steps, a conductive loop can be formed inside the coating layer, and the electroluminescent powder can be simulated to give out light when the piezoelectric ceramic particles are simulated to generate voltage. With the light emitting coating disclosed by the invention, automatic light emitting can be achieved under sound or vibration, and the light emitting coating layer is suitably used for places such as a tunnel, a cave and a corridor which is not powered on.

Description

technical field [0001] The invention designs building materials, and in particular relates to a preparation method of a luminescent coating capable of absorbing shock and sound. Background technique [0002] Electroluminescence, also known as electric field luminescence, or EL for short, is an electric field generated by the voltage applied to the two electrodes, and the electrons excited by the electric field hit the luminescent center, which causes the transition, change, and recombination of electrons between energy levels to cause luminescence. a physical phenomenon. Examples of electroluminescent materials include zinc sulfide and blue diamond doped with copper and silver. There are no reports of paints that rely solely on sound or vibration to cause light to glow. Contents of the invention [0003] In view of this, the present invention provides a method for preparing a luminous coating, through which a coating can be obtained, and the coating is characterized in t...
