Embodiment Construction

[0021] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0022] A dimming film edge sealing process for PVB laminated dimming glass, comprising the following steps:

[0023] G. Cleaning: place the dimming film 1 on the platform, and clean the 0.5-10mm area of ​​the edge of the dimming film with a cleaning agent to remove oil and other impurities. Cleaning agents are generally organic solvents such as alcohol.

[0024] H. Cutting: Use a cutting tool to half-cut a step 2 of 0.5-3mm on each side of the dimming film (except for the electrodes of the dimming film, because the electrodes of the dimming film have already formed a step); the cutting tool used in this case is Electrode machete or laser cutter. That is to say, the electrode machete for cutting electrodes can be used for cutting, and there is no need t...

Abstract

The invention discloses a smart film edge sealing technology for laminated PVB (polyvinyl butyral) smart glass. The smart film edge sealing technology includes: cleaning: placing a smart film on a platform, cleaning areas within 0.5-10mm from edges of the smart film, and removing oil contaminations and other impurities; cutting: cutting the edges (except the positions of electrodes) of the smart film to form 0.5-3mm width of steps by a cutting tool; cleaning again: wiping and cleaning the cut steps; protecting the electrodes: protecting the electrodes of the smart film by adhesive tape; applying glue: subjecting the cut steps (including steps at the positions of the electrodes) of the edges of the smart film to glue application by a glue applicator; curing: curing applied glue by curing equipment so as to finish edge sealing of the smart film. The smart film edge sealing technology for the laminated PVB smart glass has advantages of good using effect and high rate of finished products.

Description

technical field [0001] The invention relates to an edge sealing process of a dimming film for a PVB laminated dimming glass. Background technique [0002] The dimming glass refers to a dimming product formed by thermally pressing a dimming film and a film between two pieces of glass, wherein the dimming film plays the role of dimming, and the adhesive layer plays the role of bonding. Dimming film is a new type of electronic light control product. Through the control of an external electric field, the rapid transformation of the dimmer film between colorless and transparent and milky white and opaque can be realized to achieve the effect of controlling the amount of light transmitted. The interlayer between the two conductive layers of the dimming film is mainly composed of polymer resin and liquid crystal, depending on the ratio of glue and liquid crystal to form a different internal structure, but the main reason for its foggy state is that the polymer network structure iso...
