Titanium nitride glass fenestrated membrane and preparation method and application
Technical field
The present invention relates to automobile window films field, specifically, the present invention relates to a kind of titanium nitride glass fenestrated membrane and its preparation side
Method and application.
Background technology
Fenestrated membrane is kept off after automobile side, that is, is pasted on the fenestrated membrane kept off after automobile side.Vacuum magnetic-control sputtering technology was in 90 years 20th century
Formally enter market for latter stage, experienced multiple technologies innovation, magnetron sputtering technique is by nickel, silver, titanium, gold, ceramic material etc.
Advanced aerospace alloys material uses state-of-the-art multi-cavity high-speed rotating equipment, using electric field and the high strength of magnetic principles high speed
By metallic uniform sputter in the PET base material of high-tension.The product of magnetron sputtering technique except possess good metal-like,
Outside stable heat-proof quality, also with the definition that other techniques are unable to reach and low reflective and lasting color and luster.
Titanium nitride magnetic control basement membrane is the combination of magnetron sputtering technique and nitride metal technology and produced, and uses titanium nitride
Fenestrated membrane prepared by magnetic control basement membrane can reach simultaneously high-resolution, it is high it is heat-insulated, low it is reflective, without dyeing, be main flow skill in the market
Art product.Titanium nitride magnetic control basement membrane is the combination of magnetron sputtering technique and nitride metal technology and produced.Titanium nitride belongs to
Ceramic material, its titanium nitride layer of general titanium nitride magnetic control basement membrane have tens nanometers to arrive nanometer thickness up to a hundred, and titanium nitride layer is with respect to other
For sputter material it is crisp a lot, often just there is the dark line of black, the black because pad pasting work progress slightly folds to applied to fenestrated membrane
Dark line be due to titanium nitride layer it is cracked caused by (it is relatively thin to be applied to the titanium nitride magnetic control basement membrane of front its titanium nitride layer, no
Easily there is the problem), the dark line of the black is under strong sunlight it can be seen that (in-car light is weak, and to can't see the black dark outside vehicle window
Line), outward appearance is had a strong impact on, or even product quality problem can be treated as and returned goods.
The content of the invention
Based on this, the defects of the invention reside in prior art is overcome, there is provided a kind of titanium nitride glass fenestrated membrane, the titanium nitride
For glass fenestrated membrane still without the dark line of black under strong light, presentation quality is good, and with good visible light transmissivity, high ultraviolet isolating
Rate and infrared ray rejection rate, good heat-insulation effect, fenestrated membrane is kept off after automobile side being used as.
Another object of the present invention is to provide the preparation method of the titanium nitride glass fenestrated membrane.The preparation method is simple
Easy, using current ripe coating technique and complex technique, and cost is cheap.
Another object of the present invention is to provide application of the titanium nitride glass fenestrated membrane being kept off after automobile side in fenestrated membrane.
Its technical scheme is as follows:
A kind of titanium nitride glass fenestrated membrane, including be sequentially connected scratch resistant layer, titanium nitride magnetic control basement membrane, composite bed, primary colors film
Layer, mounting layer, wherein the titanium nitride magnetic control basement membrane includes polyester film and titanium nitride sputtering layer.
Gear fenestrated membrane structure has four kinds behind common titanium nitride side on the market now:(1) scratch resistant layer, titanium nitride magnetic control are followed successively by
Basement membrane (polyester film and titanium nitride sputtering layer), mounting layer, referring to Fig. 1;(2) scratch resistant layer, titanium nitride magnetic control basement membrane (polyester film
With titanium nitride sputtering layer), composite bed, laminated polyester film, mounting layer, referring to Fig. 2;(3) scratch resistant layer, laminated polyester film, composite bed,
Titanium nitride magnetic control basement membrane (titanium nitride sputtering layer and polyester film), mounting layer, referring to Fig. 3;(4) scratch resistant layer, primary colors film layer, compound
Layer, titanium nitride magnetic control basement membrane (titanium nitride sputtering layer and polyester film), mounting layer, referring to Fig. 4.Above-mentioned four kinds of structures easily go out
The dark line of existing black, wherein, (4) kind is primary colors film layer and the warp of reflection-type basement membrane (including magnetic control basement membrane and aluminium plating basement membrane) collocation
Allusion quotation structure, the structure have using reduce internal reflection rate (GA/T744-2003 require Sunshade film visible light reflectance should be less than
In 20%), therefore the visible light transmissivity selection space of the reflection-type basement membrane of the structure is big, but still is difficult to solve the dark line of black
Problem.The present invention have adjusted primary colors film layer, composite bed, the position of titanium nitride magnetic control basement membrane, pass through the optimization of structure and material
