Problems solved by technology

[0004] Generally, there are two methods of film application: manual film application and mechanical film application. Since the window glass is a curved glass with a certain radian, the mechanical film application method cannot be used. The dimming film can be switched from transparent to opaque under the condition of power on and power off, so it is necessary to effectively prevent the PDLC film applied to the window glass from bending and electrochemical corrosion

Embodiment 1

[0041] Embodiment 1 The bonding method of the ultra-thin PDLC film for vehicles of the present invention

[0042] Including the following steps:

[0043] (1) Cleaning the window glass: Spray water evenly on the surface of the window glass from the middle to the outside and from top to bottom to check for large dust particles, and use a straight-handled plastic water scraper to remove the water and water on the glass surface. Dust particles are scraped off without leaving water marks and dust particles;

[0044] (2) Film cutting: According to the shape and size of the window glass, cut the PDLC film for vehicles, and take the metal frame outside the glass as the baseline, and reserve a margin of 1CM outward;

[0045] (3) Edge trimming: cut the film according to the actual size of the glass edge, and reserve the electrode installation position;

[0046] (4) Pre-formed baking film: use wet baking to heat the PDLC film for vehicles with a hot air gun; the temperature is 120°C, a...

Abstract

The invention relates to the technical field of glass film bonding, in particular to a bonding method of PDLC films for vehicles. The bonding method of the PDLC films for the vehicles comprises the steps of vehicle window glass cleaning, film cutting, trimming, preshaping and film baking, film bonding on finished products, water and bubble removal, shaping by baking, edge sealing, electrode connection, electrode glue sealing and the like. Films are bonded on the finished products after preshaping and film baking, so that adjustment is convenient due to inaccurate alignment, and the pass percent of the finished products is increased; and the edges of the PDLC films are protected by sealing strips, so that electrochemical corrosion caused by water in air invading into liquid crystal layers is prevented, and the service life of the PDLC films for the vehicles is prolonged. The bonding method of the PDLC films for the vehicles is simple in operation and convenient to use, and can effectively improve the installation speed.

Description

technical field [0001] The invention relates to the technical field of glass film sticking, in particular to a bonding method of a PDLC film for vehicles. Background technique [0002] With the increasingly severe energy problems, energy saving and environmental protection have become the mainstream trend advocated by social development. Many building exterior walls and automobile glass use PDLC intelligent dimming film, which can not only protect the privacy of users, but also have the function of blocking ultraviolet rays and infrared rays. , reduce the radiant heat of sunlight in the interior space, and save electricity for air conditioning. [0003] Traditional car film does not have the function of adjusting transparency, cannot effectively protect user privacy, and is relatively weak in blocking ultraviolet and infrared rays, while smart dimming film has multiple functions of blocking ultraviolet and infrared rays, adjusting transparency, and protecting privacy , with...
