Problems solved by technology

[0003] The anti-radiation layer of the screen protective film is generally combined with the PET base film by high-temperature sputtering, evaporation or chemical deposition. However, the preparation process of the sputtering method is complicated, and the sputtering process needs to be completed under high temperature conditions, resulting in equipment and product costs are high; although the production cost of the evaporation method is lower than that of the high-temperature sputtering method, it is not suitable for refractory metals and high-temperature-resistant dielectric materials, so its use is limited; The production and growth speed cannot be controlled, so it is difficult to prepare ideal and complex film materials, and the product performance is not high

Embodiment 1

[0030] After unwinding and tensioning the PET film through a special optical film coating machine, dust removal, static electricity removal and corona treatment, the composite adhesive layer polyalcohol resin is coated on the treated surface; the average particle size is 40nm nanometer indium tin oxide powder Add polycarboxylate sodium salt HT-5040 to the mixed nano-silica powder with an average particle size of 100nm and disperse it into a suspension by sand milling; the suspension is coated by anilox roller Coated on the composite adhesive layer of the PET film, and finally preheated the PET film coated with the mixed nano-powder at 60°C for 1, and then placed it under an ultraviolet curing device for curing for 15 seconds to obtain a radiation-resistant coating film .

[0031] After testing, the UV resistance of the film reaches 99%; no particles appear in the middle part of the film; after the abrasion resistance test, the haze difference between the front and back of the ...

Embodiment 2

[0033] After unwinding and tensioning the PET film through a special optical film coating machine, dust removal, static electricity removal and corona treatment, the composite adhesive layer hydroxy acrylic resin JM8157A is coated on the treated surface; Add polycarboxylate sodium salt HT-5040 to the mixed nano-powder of powder and nano-zinc oxide powder with an average particle size of 40nm, and disperse it into a suspension by sand milling; The coating method is applied on the composite glue layer of the PET film, and finally the PET film coated with the mixed nano-powder is preheated at 100°C for 2 minutes and then placed in an ultraviolet curing device for 10 seconds to obtain radiation resistance. coated film.

[0034] After testing, the UV resistance of the film reaches 98%; no particles appear in the middle part of the film; after the abrasion resistance test, the haze difference between the front and back of the sample is less than 4%.

Embodiment 3

[0036] After the PET film is unwound and tensioned by a special optical film coating machine, dust removed, static electricity removed and corona treated, a composite adhesive layer acrylic thermosetting resin JM1625A is coated on the treated surface; nano-silver powder with an average particle size of 30nm Add polycarboxylate sodium salt HT-5040 to the mixed nano-silica powder with an average particle size of 60nm, and disperse it into a suspension by sand milling; the suspension is coated with an anilox roller Coated on the composite glue layer of the PET film, and finally placed the PET film coated with the mixed nano-powder in an oven at a temperature of 60°C for 2 minutes to obtain an anti-radiation coating film.

[0037] After testing, the UV resistance of the film reaches 99%; there are no particles in the middle part of the film; after the abrasion resistance test, the haze difference between the front and back of the sample is less than 4%.

Abstract

The invention discloses a method for preparing an anti-radiation coating film. The method comprises the following steps of: performing surface treatment on a transparent film substrate, and coating a compound adhesive layer on the treated surface; adding a dispersing agent into mixed nano powder of which the average particle diameter is 15-300 nanometers, and grinding and dispersing into a suspension by using a grinder; and coating the suspension onto a compound adhesive layer surface of the transparent film substrate, and curing into a film to obtain an anti-radiation coating film. Compared with the prior art, the method has the advantages: the anti-radiation coating film produced by adopting the method has the characteristics of uniformity and high thickness controllability of a coating formed by a coating compound, higher adhesion among film layers, and excellent product quality performance; and the method has the advantages of simple process, high efficiency, low cost and capability of realizing industrial mass production.

Description

technical field [0001] The invention relates to a preparation method of an anti-radiation coating film. Background technique [0002] With the vigorous development of electronic technology, electronic products such as mobile phones, MP4, MP5, cameras, digital video cameras, and notebook computers are being introduced from old to new. In order to prevent the screen surface of electronic products from being scratched or worn, affecting the use, and to shield electromagnetic waves and eliminate static electricity, a screen protective film is generally attached to the screen surface of electronic products. [0003] The anti-radiation layer of the screen protective film is generally combined with the PET base film by high-temperature sputtering, evaporation or chemical deposition. However, the preparation process of the sputtering method is complicated, and the sputtering process needs to be completed under high temperature conditions, resulting in equipment and product costs ar...
