Abstract

The invention discloses an explosion-proof membrane production method. The method comprises the following steps: providing a release film, putting a first uncoiler on the release film, passing the release film through a coating roller and a baking oven of a coating machine in order, then passing the release film through a composite wheel; providing an optical adhesive, adding a hardener in the optical adhesive, uniformly stirring the materials; separating the set temperature of the baking oven of the coating machine from an inlet to an outlet to a first temperature zone, a second temperature zone and a third temperature zone; providing a hardening membrane, putting a second uncoiler on the hardening membrane, passing one end of the hardening membrane through a corona machine and the composite wheel by the second uncoiler, applying a first surface of the hardening membrane and the first surface of the release film at the position of the composite wheel; turning on an explosion-proof membrane production device, coating the optical adhesive to the first surface of the release film by the coating machine, performing corona on the first surface of the hardening membrane by the corona machine, and compositing the first surface and the first surface of the release film on the composite wheel to form the explosion-proof membrane. According to the explosion-proof membrane production method, the produced explosion-proof membrane has the advantages of low cost, high quality and long service life.

Description

technical field [0001] The invention relates to the technical field of explosion-proof membranes, in particular to a preparation method for explosion-proof membranes. Background technique [0002] Explosion-proof membrane (Explosion-proof membrane) is a layer of film installed on the display screen of digital products or the front windshield of automobiles. This film has extremely high requirements on light transmission, and its price is much higher than ordinary films. [0003] The current explosion-proof film is generally composed of a release layer, a hardened layer, etc., and is bonded with optical glue. In the process of use, it was found that the explosion-proof film produced by the existing production process, the adhesion between the layers, the peeling force and the quality of the overall film are not ideal, the light transmittance is not high, and it often needs to be replaced after a period of use. Contents of the invention [0004] Based on this, the present i...
