Problems solved by technology

[0005] With PET film as the base material, many product applications can be derived, such as PET conductive film, PET optical film, etc., but the PET film itself has poor scratch resistance and wear resistance, which will be fatal to later processing and use. In order not to affect the application of PET film, a protective hardened coating will emerge as the times require
[0006] The UV curing liquid system cures quickly, the film forming time is relatively fast, the hardness of the film is high, the scratch resistance is good, the optical performance is good, the volume shrinkage is small during the curing process, and there is no residue of small molecular compounds, but the existing UV curing in the market Liquid, high viscosity system, large volume shrinkage of coating film, poor adhesion, easy to turn yellow, and residual UV monomer

Embodiment 1-5

[0036] The preparation methods of Examples 1-5 are:

[0037] 1) Mix 1-hydroxy-cyclohexyl benzophenone and 2,4,6-trimethylbenzoyl-diphenyl phosphine oxide in a container at room temperature;

[0038] 2) Add methyl ethyl ketone, propylene glycol methyl ether and 4-methyl-2-pentanone into the container, and stir at 500r / min for 2.5h and stir evenly;

[0039] 3) Add the high-functional aliphatic urethane acrylic resin to the container, continue to stir at 500r / min for 2.5h, stir evenly, and then use a 10nm filter bag for pressure filtration to obtain the UV hardening liquid for PET electronic film.

[0040] The prepared products of Examples 1-5 were placed in a clean opaque container during storage, and sealed for storage.

Abstract

The invention discloses UV hardening liquid for a PET electronic membrane. According to the key points of the technical scheme, the UV hardening liquid for the PET electronic membrane comprises the following components by weight percent: 16-20% of butanone, 23-25% of propylene glycol monomethyl ether, 10-14% of 4-methyl-2-pentanone, 1.6-2% of 1-hydroxyl- phenylcyclohexyl ketone, 0.4-0.8% of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide and 40-45% of highly functionalized aliphatic polyurethane acrylic resin. The invention aims at overcoming the defects of existing solvent type UV hardening paint and providing economic applicable UV hardening liquid which is used for the PET electronic membrane, simple in preparation technology and convenient and efficient to use and has excellent optical and physical properties after film formation. The invention provides a preparation method of the UV hardening liquid. The invention also provides application of the UV hardening liquid.

Description

[0001] 【Technical Field】 [0002] The invention relates to a UV hardening liquid for PET electronic film, a preparation method and application thereof, and belongs to the technical field of resin coatings. [0003] 【Background technique】 [0004] PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, and optical grade mirrors. Surface protection and other fields. [0005] With PET film as the substrate, many product applications can be derived, such as PET conductive film, PET optical film, etc., but the PET film itself has poor scratch resistance and wear resistance, which will be fatal to post-processing and use In order not to affect the application of PET film, a protective hardened coatin...
