Embodiment 1

[0047] Soak the slides in 2% hydrochloric acid for several hours to wash away the hydrochloric acid. Then put it in the detergent solution and soak it overnight, rinse it with water, soak it in distilled water or dry it and put it in a box for later use. According to parts by weight, take 100 parts of polylactic acid, 30 parts of polybutylene adipate terephthalate, and 20 parts of polymethyl methacrylate in 40,000 parts of dichloromethane, 6,000 parts of chloroform, and 4,000 parts of ethanol. part of the mixed solution. Pour the prepared solution into the container, use a lifting device, insert the cleaned glass slide into the solution at θ=90 degrees, and immediately pull the glass slide to the liquid surface at a speed of 100 mm / min and θ=90 degrees As mentioned above, the surface of the glass slide is coated with a certain thickness of polymer coating, and it is left to stand under natural conditions until the solution is completely evaporated. Gained slide glass that is...

[0049]Soak the slides in 2% hydrochloric acid for several hours to wash away the hydrochloric acid. Then put it in the detergent solution and soak it overnight, rinse it with water, soak it in distilled water or dry it and put it in a box for later use. According to parts by weight, 100 parts of polylactic acid and 10 parts of polybutylene adipate terephthalate were weighed and dissolved in 80000 parts of dichloromethane. Pour the prepared solution into a glass beaker, and use a pulling device to insert the cleaned glass slide into the solution at θ=80 degrees, and immediately pull the glass slide to the liquid surface at a speed of 400 mm / min and θ=80 degrees As above, the surface of the glass slide is coated with a certain thickness of polymer coating, and it is left to stand under natural conditions until the solution is completely evaporated, and the above pulling operation is repeated once. Gained slide glass that is loaded with interference film is put into constant tem...

Abstract

The invention belongs to the technical field of flocculating agents, and discloses an interference rainbow film solution formula, a color-controllable interference film and a preparation method of theinterference film. The solution formula comprises resin components by the gram and solvent components in milliliters; the resin components comprise, by weight, at least one of 80-100 parts of polylactic acid, 30-40 parts of polyadipate butylene terephthalate, 20-40 parts of polymethyl methacrylate, 10-30 parts of a acrylonitrile-butadiene-styrol copolymer, 10-20 parts of polystyrene, 10-20 partsof a styrene-butadiene-styrol segmented copolymer and 20-30 parts of a styrene-isoprene-styrol segmented copolymer; the solvent components comprise, by volume, at least one of 2000-80000 parts of dichloromethane, 5000-10000 parts of trichloromethane, 300-5000 parts of acetone and 4000-8000 parts of ethyl alcohol; and the color-controllable interference film is obtained.

Description

technical field [0001] The invention belongs to the technical field of optical thin films, and in particular relates to an interference iris solution formula, an interference thin film with controllable color and a preparation method thereof. Background technique [0002] Polymer materials are mainly given a variety of colors by adding pigments or dyes through physical or chemical actions. Usually, the color masterbatch is compounded with the matrix polymer during the processing process. This method is relatively low in cost, but the compatibility between the small molecule of the pigment and the polymer is poor, migration is easy to occur, and the service life of the material is affected. There is also a method of coloring by chemical force in the material synthesis process. Although the fastness is high and the controllability is strong, the cost is relatively high. The iridescent film is completely different from the color plastic film printed and dyed in ordinary colors...
