preparation example Construction

[0023] like figure 1 As shown, the preparation method of the high-sensitivity mobile phone protective screen full-fit adhesive of the present invention comprises the following steps:

[0024] S1, acrylate active monomer and photoinitiator are heated and mixed;

[0025] S2, add oligomer, polymerization inhibitor and leveling agent again, stir and mix;

[0026] S3, add wetting agent again;

[0027] S4, filter the mixture to obtain the finished product.

[0028] In step S1, the heating and mixing temperature is 40-50°C, and stirring is carried out at 1200-2000r / min for 40-45min; the stirring time in step S2 is 30-45min, and the stirring time in step S3 is 10-15min; In step S4, a 300-mesh filter is used to filter the mixture, and the filtrate is packaged to obtain the full bonding adhesive for the mobile phone screen protective film.

[0029] In addition, in the preparation method of the high-sensitivity mobile phone protective screen full-fit adhesive of the present invention...

Embodiment 1

[0040] A method for preparing a high-sensitivity mobile phone protective screen full-fit adhesive. Calculated by mass fraction, first weigh 8% acryloylmorpholine, 8% isobornyl acrylate, 32% ethoxyethoxyethyl acrylate, Mix 32% 2-phenoxyethyl acrylate, 2% acyl phosphine oxide and 2% benzoin, heat to 40-50°C, and stir at 1200-2000r / min for 40-45min. Then add 7% urethane acrylate oligomer, 3% polyether acrylate oligomer, 4% epoxy acrylate oligomer and 0.8% polymerization inhibitor in turn, after stirring for 20-30min, add 0.1% moistening The aerosol and 0.1% leveling agent are stirred for 10-15 minutes, filtered through a 300-mesh filter, and the filtrate is packaged to obtain a full-fit adhesive for the mobile phone protective screen. The properties of the obtained mobile phone protective screen full-fit glue are as follows:

[0041]

[0042] Compared with the prior art, the present invention has the following beneficial effects: the proportion of oligomer is low, so that the...

Abstract

The invention discloses a high sensitivity mobile phone protection screen full lamination adhesive and a preparation method thereof. The high sensitivity mobile phone protection screen full laminationadhesive comprises, by mass fraction, 10-20% of an oligomer, 70-90% of an acrylate active monomer, 2-6% of a photoinitiator and 1-3% of assistants. The high sensitivity mobile phone protection screenfull lamination adhesive provided by the invention not only has the characteristics of high sensitivity, high transparency, low odor, high lamination degree, environmental protection, etc., also is not added with any solvent, has heavy metal, toluene, formaldehyde, methanol meeting the EU ROSH and REACH standards, and has good peeling performance.

Description

technical field [0001] The invention belongs to the technical field of chemical products, and relates to a mobile phone protective screen fully laminating glue, in particular to a high-sensitivity mobile phone protective screen fully laminating glue and a preparation method thereof. Background technique [0002] Mobile phone screen protective film, also known as mobile phone beauty film and mobile phone protective film, is a cold lamination film used for mounting mobile phone screens. From the initial simple anti-scratch protective film to the introduction of functional protective film series, it can be divided into: anti-peeping film, AR film, frosted film, high-definition film, anti-scratch protective film, 3D film, tempered film, etc. Zhengdao mobile phone film can protect Eyesight, no damage to eyes, multi-layer protection, effectively block ultraviolet rays, short-wave blue rays, soft glare light source stimulation, attached with AF coating, so that the phone's film fee...
