Embodiment 1

[0025] According to the weight percentage, mix high-density polyethylene 10%, low-density polyethylene 84.2%, N-hydroxyethyl acrylamide 4%, processing aid calcium stearate 0.8%, and phenolic antioxidant 1010 1.0%. It is processed in a twin-screw extruder with a diameter ratio of 38:1. The temperature of the twin-screw extruder from the feeding section to the die is 150℃, 150℃, 155℃, 155℃, 160℃, 160℃, 160 ℃, 160℃, 160℃, extrude and granulate to obtain PE film material masterbatch;

[0026] After the PE film material masterbatch is blown into a film, UV cross-linking is performed under ultraviolet light with a wavelength of 370 nm for 2 hours to prepare a super-adhesive PE film material.

Embodiment 2

[0028] According to weight percentage, linear low-density polyethylene 95.6%, N-hydroxyethyl acrylamide 3%, processing aid calcium stearate 0.3%, zinc stearate 0.3%, amine antioxidant V703 0.4%, amine Antioxidant UV3808PP5 0.4% is mixed and then added to a twin-screw extruder with a length-to-diameter ratio of 36:1. The temperature of the twin-screw extruder from the feeding section to the die is 165℃, 165℃, 165℃, 170°C, 175°C, 175°C, 180°C, 180°C, 180°C, through extrusion granulation to obtain PE film material masterbatch;

[0029] After the PE film material masterbatch is blow-molded into a film, UV cross-linking is performed under ultraviolet light with a wavelength of 370 nm for 1.5 hours to prepare a super-adhesive PE film material.

Embodiment 3

[0031] According to the weight percentage, low-density polyethylene 92.9%, N-hydroxyethyl acrylamide 5%, zinc stearate 0.9%, phosphite antioxidant 168 1.2% are mixed and then added into the twin screw with a length to diameter ratio of 38:1 Processing in the extruder, the temperature of the twin-screw extruder from the feeding section to the die is 180℃, 180℃, 185℃, 185℃, 185℃, 190℃, 190℃, 190℃, and 190℃. Extrusion granulation to obtain PE film material masterbatch;

[0032] After the PE film material masterbatch is blown into a film, UV crosslinking is performed for 2.5 hours under ultraviolet light with a wavelength of 365 nm to prepare a super-adhesive PE film material.

Abstract

The invention discloses a super-viscous PE film material and a preparation method thereof. The material is prepared from 91.5%-97.1% of PE, 2%-6% of N, N-hydroxyethyl acrylamide, 0.5%-1% of processingaid and 0.4%-1.5% of anti-oxidant according to weight percentage. N-hydroxyethyl acrylamide is used as a modification auxiliary agent; a cross-linked network structure is formed in the PE film; the problems that an existing PE film is poor in adhesive force and cannot be repeatedly stripped for use are solved, the prepared super-viscous PE film material has high adsorption capacity, the integrityof the film can still be kept after repeated stripping-adsorption, the super-viscous PE film material has good adsorption capacity, and the repeated utilization rate of the PE film is greatly increased.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to a super-adhesive PE film material and a preparation method thereof. Background technique [0002] Polyethylene (PE) materials are widely used in various fields due to their better mechanical properties, chemical resistance and aging resistance. In particular, because of the good processing properties of PE materials, they can be prepared into films, which can be used in protective film fields such as packaging, advertising, household appliances and automobiles. [0003] The requirements for the film material should generally have good adhesion to the coated substance. The existing PE film mainly uses the electrostatic effect of the PE film itself to adsorb or glue the PE film to the coated object, but the aforementioned two Both methods have many shortcomings: the use of the electrostatic effect of the PE film to absorb, the adhesion is poor, and the PE film will peel off wi...
