With reference to Fig. 1~Fig. 3, the capacitive touch screen of the high-low temperature resistant including capacitive touch screen ontology 1 and is set to electricity
High-low temperature resistant coating 2 in appearance formula touch screen body 1, capacitive touch screen ontology 1 include 10 lower section of protective layer 10 and protective layer
Electrode layer 11, the first conducting shell 12,13 and second conducting shell 14 of glass set gradually, high-low temperature resistant coating 2 include being set to
The first silicate solutions coating 20 between electrode layer 11 and protective layer 10 and the second silicon for being set to 14 lower section of the second conducting shell
Acid salt solution coating 21.
First silicate solutions coating 20 and the second silicate solutions coating 21 are separately positioned on electrode layer 11 and the
It,, can be from elder generation due to the heat that equipment work generates when capacitive touch screen ontology 1 is mounted in equipment under two conducting shells 14
The second conducting shell 14 is reached again by the second silicate solutions coating 21, when by the second silicate solutions coating 21, due to
The characteristic of silicate solutions, heat will weaken significantly, and the second conducting shell 14 is protected not influenced by extreme temperature；From outside
High and low temperature contact protection layer 10 first, using the first silicate solutions coating 20, finally reach electrode layer 11, equally by
In the characteristic of silicate solutions so that external high and low temperature is across weakening after the first silicate solutions coating 20.It sets in this way
Double-deck high-low temperature resistant coating 2 good protection is played to the component in touch screen, touch screen can be made at -35 DEG C~100 DEG C
Normal work.
With reference to Fig. 3, it is preferable that the first silicate solutions coating 20 and 10 area equation of protective layer, and it is covered in protective layer
10 bottom surfaces.
First silicate solutions coating 20 is covered in 10 bottom surface of protective layer, it, also can be just in this way while convenient for encapsulation
In replacement of the maintenance personal to component.First silicate solutions coating 20 can also be directly overlayed on electrode layer 11.
With reference to Fig. 3,14 area equation of the second silicate solutions coating 21 and the second conducting shell, and it is covered in the second conducting shell
14 bottom surfaces.
Being covered in the second silicate solutions coating 21 of 14 bottom surface of the second conducting shell can allow excessively high temperature not reaching also
Just weaken during the second conducting shell 14, the influence for the second conducting shell 14 not excessive temperature that adequately protected.
With reference to Fig. 1, Fig. 3, the first silicate solutions coating 20 and the second silicate solutions coating 21 are that clear solution applies
Layer.
Since high-low temperature resistant coating 2 is covered on transparent optical element, silicate solutions coating is ideal
High-low temperature resistant coating 2 has the characteristics that transparent, resistance to extreme temperature performance is good.
Operation principle is as follows：
It, can be from first passing through the due to the heat that equipment work generates when capacitive touch screen ontology 1 is mounted in equipment
Dislicata solution coatings 21 reach the second conducting shell 14 again, when by the second silicate solutions coating 21, due to silicate
The characteristic of solution, heat will weaken significantly, and the second conducting shell 14 is protected not influenced by extreme temperature；Height from outside,
Low temperature contact protection layer 10 first, using the first silicate solutions coating 20, finally reaches electrode layer 11, also due to silicic acid
The characteristic of salting liquid so that external high and low temperature is across weakening after the first silicate solutions coating 20.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
Under every utility model in the utility model is conceived, equivalent structure made based on the specification and figures of the utility model
