Abstract
The utility model discloses a color plastic pressure diaphragm, comprising a PCB (printed circuit board) layer and a PCF (photonic crystal fiber) layer, wherein the PCB layer and the PCF layer are superposed up and down; the PCB layer comprises a first base material and a microcapsule coating layer containing a color former; the microcapsule coating layer is coated at the inner surface of the first base material; the PCF layer comprises a second base material and a color coating containing a color-developing agent; and the color coating is coated on the surface of a second base material opposite to the inner surface of the first base material. The color plastic pressure diaphragm can be used under a high-temperature condition of 0-300 DEG C, has large strength, is not easily damaged in a using process, and has good keeping quality. Meanwhile, the pressure change in use can be accurately metered, and the color plastic pressure diaphragm can display different concentrations of colors under the condition of different pressure changes, thus the planeness of a pressure head is distinguished through naked eyes or a color densitometer.
Description
Technical field
The utility model relates to a kind of colour developing diaphragm, relates in particular to a kind of plastic film that can make its colour developing by pressure.
Background technology
Pressure colour developing plastic film is based on the colour developing principle on the NCR, under different pressure-actings, show the depth of color, can pick out the uniformity of pressure that pressurized zone is born by gradation of color, and then analyze the smooth situation of pressure head.This pressure colour developing plastic film can be applied to detect the sealing situation of oil cylinder in the automobile industry, wear intensity, the glass pressing situation in the liquid crystal display industry, the printing uniformity in the printing industry, the printing homogeneous situation of various conductive metal slurries and the industries such as pressure roller contact flatness of textile industry of brake block.
The structure of NCR mainly contains two kinds: a kind of is coupled mode, at the back side of upper page or leaf paper coating colour former (CB), at the positive coating of middle page or leaf paper developer, back side coating colour former (CFB), the positive coating of nextpage paper developer (CF), the supporting use that is superimposed together, the pressure that produces in the process of printing by printer is so that scribble microcapsules rupture on the CB layer of colour former, thereby reacts with the developer that contacts, and finally shows color.Another is self-contained type, and colour former and developer are coated on the front of same paper.Yet this NCR has limitation when using in a lot of fields, because its exactly variation of metering pressure, and cause warpage because of dehydration easily in the process that common paper at high temperature uses, while causes paper worn-out larger pressure easily, so this has caused inconvenience in the use of the industries such as liquid crystal display, automobile, machinery, printing for NCR.
The utility model content
The purpose of this utility model is to solve the problems of the prior art, and a kind of high temperature resistant, not fragile, preservation effect good and the pressure of being convenient to distinguish pressure head flatness situation develops the color plastic film is provided.
The technical solution of the utility model is: a kind of pressure colour developing plastic film, comprise PCB layer and PCF layer, up and down stack between described PCB layer and the PCF layer, described PCB layer comprises the first base material and contains the enteric coating layer of colour coupler, described enteric coating layer is coated on the inner surface of the first base material, described PCF layer comprises the second base material and contains the colour developing dope layer of developer that described colour developing dope layer is coated on second substrate surface relative with described the first base material inner surface.
Described the first base material and the second base material are the PET plastic film.
The utility model can use under 0 ~ 300 ℃ higher temperature conditions, and has larger intensity, and is not fragile in the process of using, and has preferably keeping quality; Simultaneously, the utility model can measure the pressure size variation when using more exactly, and under different pressure changed, pressure colour developing plastic film can show the color of variable concentrations, thereby distinguishes the flatness situation of pressure head by naked eyes or color densitometer.

The specific embodiment
For technological means, technical characterictic, utility model purpose and the technique effect that the utility model is realized is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Be illustrated in figure 1 as a kind of pressure colour developing plastic film of the present utility model, comprise that PCB layer (scribbling the polyester film lamella of colour coupler capsule) 1 and PCF layer 2(scribble the polyester film lamella of developer), up and down stack between described PCB layer 1 and the PCF layer 2, PCB layer 1 comprises the first base material 11 and contains the enteric coating layer 12 of colour coupler, enteric coating layer 12 can be responded to the size of outside various pressure, enteric coating layer 12 is coated on the inner surface of the first base material 11, PCF layer 2 comprises the second base material 21 and contains the colour developing dope layer 22 of developer, colour developing dope layer 22 is coated on second base material 21 surfaces relative with the first base material 11 inner surfaces, and the first base material 11 and the second base material 21 are the PET(polyester film in the utility model) plastic film.
PCB layer 1 mainly makes by following several steps in the utility model: at first adopting melamine formaldehyde resin is the shell material, leuco dye is that capsule-core is made leuco dye microcapsules 13 by the high molecule emulsion polymerization reaction, obtain after the microcapsules 13, add again various auxiliary agents and adhesive, make the coating that contains microcapsules 13, then by various coating processes coating is coated on and forms enteric coating layer 12 on the first base material 11, namely obtain PCB layer 1 after the drying.
The preparation process of PCF layer 2 is as follows: at first a certain proportion of developer modified salicylic acid zinc resin and filler and various additive are made coating, then this coating is coated on the second base material 21, final drying obtains PCF layer 2.
Above-mentioned PCB layer 1 and PCF layer 2 double-layer structure fit together, when being subject to outside certain pressure 3, microcapsules 13 in the upper strata PCB layer 1 enteric coating layer 12 break, flow out the leuco dye colour coupler, modified salicylic acid zinc resin color-developing agent reaction with in the colour developing dope layer 22 namely demonstrates certain density color.
Force value corresponding to pressure colour developing plastic film colour developing situation mainly is to make by the leuco dye microcapsules of selecting different pressures value size, wherein pressure sensitive scope mainly comprises following 5 interval: 0.3 ~ 1.5MPa, 0.5 ~ 3.0MPa, 2.5 ~ 12Mpa, 10 ~ 60MPa and 50 ~ 350MPa, and is different according to the Show Color of different the utility model pressure colour developing plastic films of external pressure.
Being the utility model preferred embodiment only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
