Thin metal or organic matter layer between millimeter have optical property, electrical properties, magnetic property, chemical property, mechanical property, heat
Learn property, thin-film material have multifrequency nature thus be all widely used in many areas.
There are some films that discoloration may be implemented at present, such as WO3 optically variable films, this film can be by utilizing electric field
(electrochromism) and color is presented, this film will realize discoloration, it is necessary to utilize electric field, under no electric field action, Wu Fashi
Now change colour.
Increasingly developed with film product, different application person also proposed more requirements to the performance of film product,
Therefore the structure of existing film product also needs further exist for improved space.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, a kind of multi-level color change is provided
Film, its structure is simple, is not necessarily to electric field, can be achieved with the film of discoloration by the variation of temperature.
To achieve the above object, the utility model is using following technical scheme: it includes substrate layer 1, pattern layer 2, height
Temperature layer 3, cryogenic temperature layer 4 are provided with pattern layer 2 above the substrate layer 1, and the top of the pattern layer 2 is provided with height
Temperature layer 3, the top of the high-temperature temperature layer 3 are provided with cryogenic temperature layer 4, the high-temperature temperature layer 3 and cryogenic temperature layer 4
It is heat-sensitive variable colour microcapsules film layer.
Further, the high-temperature temperature layer 3 with a thickness of 20-30 μm, heat discoloration temperature is 31 DEG C -50 DEG C.
Further, the cryogenic temperature layer 4 with a thickness of 10-20 μm, heat discoloration temperature is 10 DEG C -21 DEG C.
Further, the pattern layer 2 is pasted on substrate layer 1 by the way of viscose.
Further, the high-temperature temperature layer 3 is pasted onto pattern layer 2 by the way of viscose.
Further, the cryogenic temperature layer 4 is pasted on high-temperature temperature layer 3 by the way of viscose.
Further, the substrate layer 1 be one of polypropylene film, polyethylene film, metallized film, substrate layer
Thick bottom is 100-200 μm.
After adopting the above technical scheme, the utility model has the beneficial effect that its structure is simple, design is reasonable, heat-sensitive variable colour
Reversible temperature-sensitive camouflage paint in microcapsules changes colour because of temperature change, and the temperature-sensitive temperature range of high-temperature temperature layer is higher than low temperature temperature
The temperature-sensitive temperature range for spending layer, enables it to show different color patterns according to different temperatures range.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: substrate layer 1, pattern layer 2, high-temperature temperature layer 3, cryogenic temperature layer 4.
Specific embodiment
Referring to shown in Fig. 1, present embodiment the technical solution adopted is that: it includes substrate layer 1, pattern layer 2, high temperature
Temperature layer 3, cryogenic temperature layer 4 are provided with pattern layer 2 above the substrate layer 1, and the top of the pattern layer 2 is provided with high temperature
Temperature layer 3, the top of the high-temperature temperature layer 3 are provided with cryogenic temperature layer 4, and the high-temperature temperature layer 3 and cryogenic temperature layer 4 are equal
For heat-sensitive variable colour microcapsules film layer.The high-temperature temperature layer 3 with a thickness of 20-30 μm, heat discoloration temperature is 31 DEG C -50 DEG C.
The cryogenic temperature layer 4 with a thickness of 10-20 μm, heat discoloration temperature is 10 DEG C -21 DEG C.
The reversible temperature-sensitive electrochromic substance of microencapsulation be known as reversible temperature-sensitive camouflage paint (be commonly called as: warm variable pigments, temperature-sensitive powder or
Temperature change powder).The particle of this pigment is spherical, and average diameter is 2 ~ 7 microns (one micron is equal to one thousandth millimeter).In it
Portion is electrochromic substance, and outside, which is about 0.2 ~ 0.5 micron of a thickness, can neither dissolve the transparent outer cover that will not melt, and exactly it is protected
Electrochromic substance has been protected from the erosion of other chemical substances.It can with the up and down of temperature and repeatedly turn colors.(with 31
For DEG C red, discoloration form is 31 DEG C of presented above colourless, 31 DEG C of red presented below).
The pattern layer 2 is pasted on substrate layer 1 by the way of viscose.
