The protective layer of military electronic product form, but electromagnetic shielding glass production cost is high in the prior art, complex process, anti-electricity
Magnetic property, intensity and light transmittance etc. are difficult to meet simultaneously, therefore are badly in need of a kind of production stabilization, the high electromagnetic shielding glass of yields
Manufacture craft.
Electromagnetic shielding glass is handled by special process, is coated conductive coating in glass surface or is sandwiched spy in glass
Different medium and realize the blocking and decaying to electromagnetic wave, reach and electromagnetic wave stopped to penetrate, prevent electromagnetic radiation, information is protected not let out
The shield glass device of dew and electromagnetism interference.Electromagnetic shielding ratio has good light transmission and high solution image, visually
Effect is good, and no net sense is more clear image.Electromagnetic shielding glass mainly solves the electromagnetism between electronic system and electronic equipment
Interference, prevents electromagnetic information from revealing, and protects electromagnetic radiation pollution；Effective guarantee instrument and equipment works normally, and ensures confidential information
Safety, safeguard work personnel's health.Therefore, electromagnetic shielding glass must satisfy two conditions: first is that good anti-electricity
Magnetic wave interference and Tempest performance；Second is that good perspective performance.Prior art electromagnetic shielding glass from performance substantially
It is divided into three classes: the electromagnetic shielding of folder wire mesh electromagnetic shielding glass, plated film electromagnetic shielding glass and coated glass folder spun gold net
Glass, most commonly used is still metal clip silk screen shield glass, but metal clip silk screen shield glass produced in the prior art
Often because fitting is not tight in journey, there are micro-bubbles between glass sandwich, cause yields low, micro-bubble both seriously affected
The integral light-transmitting of shield glass, but also expection is not achieved in laminated glass enhanced strength.
Summary of the invention
The purpose of the present invention is to solve in the prior art, the low problem of yields provides a kind of for military window
Electromagnetic shielding glass production technology, can greatly reduce glass close piece during micro-bubble generate.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:
A kind of electromagnetic shielding glass production technology for military window, which comprises the following steps:
Step 1 takes one block of sheet glass to be placed on station, utilizes dispenser dispensing on the glass sheet；
The wire mesh cut is covered on the sheet glass after dispensing by step 2；
Step 3 carries out secondary dispensing using dispenser on a wire mesh；
Step 4 separately takes one piece of glass covering on a wire mesh, and tentatively presses to top glass, makes glue in two layers of glass
The electromagnetic shielding glass that homogeneous form is tentatively bonded is bonded between glass and wire mesh；
Step 5 will tentatively be bonded electromagnetic shielding glass precompressed de-bubble in the case where vacuumizing environment obtained in step 4；
Step 6, the secondary de-bubble of pressure that the electromagnetic shielding glass of preliminary de-bubble heats up in autoclave；
Electromagnetic shielding glass after above-mentioned de-bubble is placed under UV ultraviolet environments and solidifies by step 7, obtains finished product electromagnetism
Shield glass.
As an improvement, the step 1 needs to complete in dust-free workshop to step 4.
As an improvement, the sheet glass selects high-quality float glass sheet, thickness difference meets technique requirement, after pre-treatment
Glass surface it is smooth.
As an improvement, the glue that the dispenser uses is Liquid optical clear adhesive.
As an improvement, dispensing covers wire mesh after glue Self-leveling again in step 1.
As an improvement, the electromagnetic wavelength type that the mesh diameter of the wire mesh shields as needed is selected, net
The cutoff wavelength of Kong Yue great, wire mesh shielding are bigger.
It is laid with as an improvement, the wire mesh chooses certain angle, can first make multiple and different wire mesh fittings
The electromagnetic shielding glass of angle, record number write down the wire mesh fitting angle of not Moire fringe, according to the angle
Carry out wire mesh fitting.
As an improvement, the material of the wire mesh is using copper, aluminium, galvanized wire, stainless steel wire, filamentary silver and silver-plated
Any one in twine.
As an improvement, the electromagnetic shielding glass after preliminary fitting is transferred to froth in vacuum by vacuum chuck in step 4
De-bubble is carried out in machine.
The medicine have the advantages that
The present invention combines the full attaching process of conventional screen with electromagnetic shielding technique, the product yield produced
Height, de-bubble effect is good, and anti-effectiveness is good, by the selection of wire mesh angle it is possible to prevente effectively from Moire fringe
Appearance, the LOCA translucency that the present invention uses is good, and colorless and transparent, 98% or more light transmittance, adhesive strength is good, can in room temperature or
Solidify under medium temperature condition.And there is the features such as cure shrinkage is small, color inhibition simultaneously.Compared with traditional OCA adhesive tape, LOCA exists
Certain application fields have special advantage, can solve the limitation that OCA adhesive tape is faced.Liquid optical cement LOCA has high saturating
Photosensitiveness, adhesive strength height and easy folding glue are reprocessed unqualified adhesive, high adhesion strength, high durable, water resistance, high temperature resistant, are resisted
Ultraviolet light, for a long time use will not product xanthochromia, removing and rotten problems.Therefore electromagnetic screen can be greatly improved by LOCA
Cover the translucency of glass.In addition the present invention uses two step bubble removing methods, good to bubble removal effect, can effectively reduce glass sandwich
Interior micro-bubble residual, can not only improve electromagnetism glass transmission, moreover it is possible to improve the mechanical performance of electromagnetic shielding glass.
