| titleOfInvention | The preparation method of iodine based dye, iodine polarizing film |
| abstract | The invention provides the preparation method of a kind of iodine based dye, iodine polarizing film, polyvinyl alcohol resin, plasticizer are mixed with surfactant, prepare polyvinyl alcohol film; Described polyvinyl alcohol film is dyeed in iodine based dye, carry out uniaxial tension simultaneously, then in air, carry out dry method tension, after being dried, obtain iodine polarizing film; Described iodine based dye comprises povidon iodine complex compound, buffer, stabilizing agent, KI and solvent. Compared with prior art, the present invention is taking povidon iodine complex compound as main coloring matter, and what it can be controlled dissociates elemental iodine, and the polyvinyl alcohol film required iodine that dyes is provided, and then can effectively control speed and the uniformity of dyeing; Simultaneously povidon iodine complex solution is acid, is the pH value of dye liquor by controlling iodine, not only can improve its stability series, also can be fixed the dyeing of polyvinyl alcohol film, thereby can improve the durability of iodine polarizing film. |
