Production method of patterned toning film

Abstract

The invention relates to a method for producing a patterned toning film, comprising the following preparation steps: step 1, preparing a conductive solution; step 2, using a reverse coating roller to coat the conductive solution on a transparent film; after coating, the surface is conductive The resistance of the body reaches 40-70Ω / □; Step 3, fix the positive electrode pattern conductive layer film and the negative electrode pattern conductive layer film on both sides of the liquid crystal coating machine respectively, the positive electrode conductive area, the negative electrode The conductive areas are arranged oppositely; the PDLC liquid crystal is coated between the positive electrode pattern conductive layer film and the negative electrode pattern conductive layer film; and the patterned toning film is obtained by drying and winding. The patterned toning film prepared by the invention has simple structure and is easy to manufacture; and different reverse coating rollers can be made according to the needs of customers to obtain patterned toning films with different patterns. The pattern outline is made by printing, and the graphics are exquisite , delicate and good display effect.

Description

technical field [0001] The invention relates to a preparation method of an intelligent PDLC liquid crystal toning film with special patterns or characters. Background technique [0002] PDLC liquid crystal dimming film is formed by mixing nematic liquid crystal and polymer and curing between two transparent conductive films; in the absence of electric field, the internal liquid crystal presents a disordered orientation state, which will cause light scattering , the color film is opaque and opaque; when the electric field is connected, the molecules of the micron-level liquid crystal are arranged in an orderly manner under the action of the electric field, and the refractive indices of the molecular polymer and the liquid crystal material tend to be the same, which greatly inhibits light scattering, so that the liquid crystal adjusts The light film is colorless and transparent. [0003] Due to the inherent characteristics of liquid crystal toning film, it is currently widely...

[0005] At present, the Chinese Patent Publication No. CN110471205A discloses a method for preparing a PDLC liquid crystal dimming film containing nano-silver wire transparent conductive film. The electrode control is formed by the nano-silver wire to control the pattern; however, the arrangement of the silver wire is difficult, and the formed The pattern should not be too complicated, otherwise the verification will affect the routing efficiency

[0006] Chinese Patent Publication No. CN208737145U PDLC liquid crystal dimming film and insulating glass with NX×NY display mode adopts an electrode array to realize fixed-area electrification and fixed-area development, and applies liquid crystal display technology to PDLC liquid crystal dimming film , which greatly expands its application scope; however, this application method has high cost, and is affected by the accuracy of the dot matrix, and the image accuracy is poor, so it is only suitable for displaying text content
