Problems solved by technology

[0005] In order to solve the above problems, the cold lamination films currently on the market can enhance the texture of the picture, protect the picture (printing surface), and have relatively good scratch resistance and water resistance, but none of them can make the photo image highly anti-corrosion and anti-ultraviolet erosion Ultraviolet rays will penetrate the cold lamination film to make the picture f...

Embodiment 1

[0025] A preparation process of a cold lamination film with shape memory properties, the preparation process of the cold lamination film with shape memory properties comprises the following steps:

[0026] 1) Dissolve hydroxyacrylic resin, polycaprolactone diol and additives in excess butyl acetate solution, stir evenly, and heat and stir in a water bath at 40°C for 10 minutes to obtain a uniform mixture;

[0027] 2) Add curing agent and catalyst to the homogeneous mixed solution obtained in step 1), mix and stir, and reflux to collect the refluxed liquid under the condition of 35°C water bath, until the solution system changes from colorless to slightly yellow or turbid, stop, and add to Add the reflux liquid dropwise to the solution system until the solution has no turbidity and returns to colorless, and a thick slurry is obtained;

[0028] 3) Put the thick slurry obtained in step 2) into a flat vulcanizer for hot pressing, preheat at 160°C for 8 minutes, hold the pressure a...

Abstract

The invention relates to a cold laminating film with ultra-strong oxidation and aging resistance, long service life, high transparency, high flexibility and a shape memory characteristic. Compared with the prior art, the cold laminating film has good ultraviolet aging resistance, can be used in the outdoor large advertisement setting process, and has long service life under long-time solar radiation. Compared with a cold laminating film prepared in the prior art, the cold laminating film is not easily oxidized, yellowed or embrittled, free radicals generated on the film with the shape memory characteristic after irradiation modification are increased and react with antibacterial monomer, the antibacterial monomer can similarly generate free radicals after electron beam irradiation modification, ionic copolymerization happens, antibacterial mildew-proof capacity is enhanced, the cold laminating film has the shape memory characteristic that a common cold laminating film does not have, and easily broken articles such as photos or large advertising paper are more effectively protected.

Description

technical field [0001] The invention relates to the field of cold lamination films, in particular to a cold lamination film with shape memory properties, which has strong anti-oxidation and aging ability, long service life, high transparency, high flexibility and shape memory properties. Background technique [0002] Cold lamination film is made of transparent PVC through adhesive processing. According to the texture of the film surface, it can be divided into light film, matte film, frosted film, star illusion film, laser film and protective film with special texture. It is widely used in advertising production. The most popular are glossy film, matte film and frosted film. The cold lamination film is laminated on the photo printing screen by hand or with a cold laminator to prevent the screen (printing surface) from being scratched, polluted or wet, and to protect the screen. It can be widely used in the mounting protection and preservation of wedding photos, oil painting...
