Problems solved by technology

[0002] Phosphorescent film is one of the luminescent materials, also known as luminous film, which refers to the use of the characteristics of chemical molecular structure, and the principle of absorbing light to a certain extent and slowly emitting light. Luminous, play a clear and guiding role in the dark, widely used in subways, shopping malls, high-rise safety passages, house numbers and other fields. The surface of the light-storing film has a PET layer, and the PET film has excellent barrier properties and strong leakage resistance , the solvent is difficult to penetrate, and the inhalation of the solvent is poor, so it can only be used for lettering, but it cannot be sprayed, and it cannot be screen printed. High temperature, can not also laser engraving, needs further improvement

preparation example Construction

[0025] The preparation method of modified coating 1 comprises the steps:

[0026] (1) First add ethyl acetate into the mixing tank, then add butyl acetate, cyclohexanone, fluorine-modified acrylic leveling agent, polyester resin, and hydroxy acrylic resin in order while stirring, and then use 900-1100r / min Stir for 10-15min;

[0027] (2) Add curing agent to the mixing tank after stirring in step (1), stir at 900-1100r / min for 8-12min, pass through a 250-350 mesh sieve to obtain the modified coating 1.

[0028] A method for preparing a light-storing film: the modified coating 1 is coated on the surface of the PET layer 2 by a roll coater, the thickness of the coating knife edge is 180-220um, the coating speed is 5-15m / min, and the coating temperature is 65-150°C .

Abstract

The invention discloses a light-storing film, a modified coating and a preparation method. The modified coating for the light-storing film is prepared from raw materials in parts by weight as follows:hydroxy acrylic resin, polyester resin, ethyl acetate, butyl acetate, cyclohexanone, a curing agent and a levelling agent; the modified coating takes hydroxy acrylic resin and polyester resin as mainraw materials, takes ethyl acetate and butyl acetate as solvents, cyclohexanone, the curing agent and the levelling agent are taken as auxiliary raw materials, all materials cooperate with one another, so that the modified coating formed on a PET layer has the advantages of high-temperature resistance, high solvent absorption and high adhesion, and laser inscription, digital inkjet and silk-screen printing of the finally prepared light-storing film can be guaranteed.
