Abstract
A decorative thermochromic liquid crystal membrane is made up through coating prepared liquid crystal onto transparent substrate with drawn pattern, covering a layer of polyester film to form a complex membrane and sealing it with thermosetting resin or paints, and features that its colour can invertibly change with temp. Its advantages include gay and rich hues, better thermochromic effect, unique nacreous and diffractive lustre. The liquid crystal membrane can be used for art works, decorations, toy and special marker.
Description
What the present invention relates to is the application technology of liquid crystal, particularly a kind of method for making that is used for the liquid crystal clamp film of merchandise marks, decoration, workmanship.
As a member in the liquid crystal extended familys with various special natures, thermo-varing liquid crystal is because the variation that can come response temperature with change color has wide practical value in modern science and technology numerous areas and people's daily life.As aspects such as temperature indication, printing, pathology examination and nondestructive inspection, thermal recording material, weaving, special marking, decoration, industrial art, microwave measurements application is arranged all.
Because thermo-varing liquid crystal is thick when its Show Color changes; there are simultaneously problems such as easily contaminated, oxidation again; therefore; when using thermo-varing liquid crystal, need take protective measure; the mode of the most normal employing at present is the G-A microcapsule methods that propose based in the BP 1138590 (1969); be the wall material with gelatin and Arabic gum promptly, liquid crystal is a heartwood, and the wall material is solidified.Chinese patent CN85 for another example, 1.04765A what propose is the wall material with the resin, liquid crystal is the microcapsule method of heartwood etc., the readability of liquid crystal display is all owing to light random scattering on the wall material is had a greatly reduced quality, the wall shell also has suitable infringement to the form and aspect of liquid crystal, some tones very weak in temperature changing process have been masked, and therefore thermo-varing liquid crystal had the extremely strong diffracting power of visible light originally also loses.So just reduced the cosmetic value of liquid crystal greatly.Also having a kind of method is the liquid crystal perforated membrane, as the brilliant thermometer of Japanese production fluid that we buy on market, equally also has to exist and microcapsules liquid crystalline phase shortcoming together, has not both observed the distinctive nacreous lustre of liquid crystal, does not also observe the extremely strong diffraction gloss of liquid crystal.
The purpose of this invention is to provide a kind of weak point that can remedy said method, can keep original color developing effect of liquid crystal and characteristic again, technology is simple, the thermo-varing liquid crystal clamp film preparation method that the cycle is short.
Thermo-varing liquid crystal clamp film preparation of the present invention is achieved in that at first selects suitable transparent base, as plastic sheeting, sheet, poly (methyl methacrylate) plate, glass etc., the transparent substrate face is cleaned with organic solvent earlier, wash with distilled water again, then dry with the acetone washing, on substrate, paint with required pattern, then with directed agents treatment substrate surface and place on one 50～70 ℃ the workbench, with composite liquid crystal with being coated with pen or instruments such as silk screen, coat pattern part with craft or mechanical system, carefully multiple on liquid crystal with polyester film again, at last with transfer thermosetting resin that the black filler is arranged or paint etc. to be sealed, promptly get after the curing drying can demonstrate along with variation of temperature gorgeous colorful and have a liquid crystal clamp film of extremely strong diffraction light.If adopt and be coated with composite liquid crystal again in the polyester film back, one deck polyester film one deck liquid crystal, the mode of multilayer can make the color development area broad repeatedly, and the colour developing cycle is more, the liquid crystal clamp film that color and luster is abundanter.
The used composite liquid crystal of the present invention adopts the means of Recompounded multielement according to the minimum solid fusing point principle of solid solution, and in addition anti-curing agent and antioxidant, and the phenomenon that the colour developing that causes is worse off is solidified in the crystallization that can suppress liquid crystal effectively.The single liquid crystal of forming composite liquid crystal has: cholesteryl nonanoate (being designated as A); cholesteryl benzoate (being designated as B); cholesterine ten carbonic esters (being designated as C); cholesterine capronate (being designated as D); cholesterine cinnamate (being designated as E); cholesterine lauroyl carbonic ester (being designated as F); cholesterine isobutyryl carbonic ester (being designated as G); cholesteryl oleoyl carbonate (being designated as H); the different propiono carbonic ester of cholesterine (being designated as I) cholesterine bytyry carbonic ester (being designated as J); cooperate in all proportions in ten kinds of single liquid crystal; all include E in its various cooperations; and add anti-curing agent cholesterine 2 ethyl hexanoic acid ester (being designated as K) and antioxidant 2; 6-DI-tert-butylphenol compounds (being designated as L) etc. adopt fusion method or dissolution with solvents method that liquid crystal is mixed evenly and except that desolvating and make composite liquid crystal.
The used encapsulant of the present invention is heat reactive resin or lacquer class material.
Thermo-varing liquid crystal clamp film preparation method's of the present invention characteristics are: the peripheral material of making liquid crystal clamp film all is popular materials cheap and easy to get, it is simple to make the liquid crystal clamp film equipment needed thereby, operating condition is easily gone, process cycle is short, the liquid crystal consumption is few, the liquid crystal clamp film display effect of making is good, and is not only bright in colour, also can observe different colours from different perspectives.Therefore, be the development and use thermo-varing liquid crystal, improving added value of product provides advantageous conditions.
By embodiment can the invention will be further described better.
