Description
Technical field
The present invention relates to the manufacturing technology of photochromic glass, especially a kind of preparation of broadband phototropic heat-protecting glass
Method.
Background technology
Photochromic glass refers to after the irradiation of the light of a certain wave band, and the light transmittance of glass changes, and color usually becomes
It is deep, when light source is removed, and a kind of glass material of original state can be restored to.A kind of photochromic often reversible process,
Often, service life is long for good photochromic material possibility of reversal.Photochromic glass can be applied to automotive glazing, building door
Window or cladding glass and other fields.
The photochromic material that photochromic glass uses can be divided into inorganic photochromic material and organic photochromic material.Before
It is slower that person usually becomes bleaching time, and discoloration amplitude is shallower, and service life is longer；It is very fast that the latter usually becomes bleaching time, and change colour width
Degree is deeper, and service life is shorter.
The photochromic material being commonly used, inorganic photochromic material such as silver halide, tungstic acid etc., You Jiguang
Cause off-color material such as chromene, aphthopyrans etc., however, inorganic or organic photochromic material, to wavelength be 200~
The ultraviolet radiation range of 380nm can generate discoloration, be not easy to produce to the visible optical radiation range that wavelength is 380~780nm
It changes and color or does not generate discoloration.
Current existing photochromic glass has one layer, two layers, three layers, five layers or seven-layer structure.Wherein：
The photochromic glass of one layer of structure is that silver halide is added under glass melting state such as silver halide darkening glass, is lacked
Putting is：Technique controlling difficulty is big, and dispersibility, the stability of silver halide are poor, and noble metal is of high cost, it is difficult to popularize and arrive usage amount
The fields such as big automotive glazing, building doors and windows or cladding glass.
The photochromic glass of two-layer structure such as pastes the glass of phototropic film, the disadvantage is that：There are validity periods for phototropic film
Easy degumming has been grown, bad, the disadvantage for causing photochromic material service life short has been protected to water vapor rejection, it is more difficult to which large-scale promotion is used
In fixed building doors and windows or cladding glass.
The photochromic glass of three-decker, if double-sided glass centre sandwiched is added with the hot melt adhesive layer of photochromic material
（Hot melt adhesive is PVB or EVA）, outside water vapor rejection performance is improved, the disadvantage is that：If being subject to ultraviolet light suction in hot melt adhesive layer
Agent is received, then can influence the phototropic efficiency of photochromic material, lead to that phototropic cannot be generated or phototropic amplitude is too weak, if not
Add UV absorbers to be protected, then the service life of photochromic material can be reduced, especially with organic photochromic
Material；In addition, easily making photochromic glass clear since several functions material and auxiliary agent is added in process in hot melt adhesive layer
Degree reduces.
The photochromic glass of five-layer structure, such as adds photochromic material in the film（Such as PET film）In be made light change
Color film, two sides use two hot-melt films（PVB or EVA）Five-layer structure is made in two sheet glass bonding with outside both sides,
Disadvantage still has：If being subject to UV absorbers in hot melt adhesive layer, the phototropic efficiency of photochromic material can be influenced,
Lead to that phototropic cannot be generated or phototropic amplitude is too weak, is protected if being not added with UV absorbers, light-induced variable can be reduced
The service life of color material, especially with organic photochromic material.
The photochromic glass of seven-layer structure, two face of phototropic film such as in above-mentioned five-layer structure and between hot-melt film
Water vapor rejection film is set and constitutes seven-layer structure, further enhances the water vapor rejection performance of photochromic glass, disadvantage is still
In the presence of：If being subject to UV absorbers in hot melt adhesive layer, the phototropic efficiency of photochromic material can be influenced, causing cannot
It generates phototropic or phototropic amplitude is too weak, protected if being not added with UV absorbers, photochromic material can be reduced
Service life, especially with organic photochromic material.
