Embodiment 1

[0016] An anti-aging PE film formula of this embodiment is prepared from the following raw materials in parts by weight: 80 parts of PE, 20 parts of PS, 5 parts of trimethylolpropane triacrylate, 3 parts of sorbitol, 6 parts of phenol, and 2 parts of formaldehyde , 4 parts of caustic soda, 2 parts of plasticizer glycerin, 1 part of thermoplastic polystyrene, 2 parts of zinc stearate, 2 parts of borax, 3 parts of kaolin, 1 part of aluminate coupling agent, and 100 parts of water.

[0017] The preparation method is as follows: weigh each component according to the weight ratio, put it into the reaction kettle, heat the reaction in the nitrogen atmosphere, and then send it into the twin-screw extruder, and the twin-screw extruded sample is water-cooled, air-dried, and pelletized , to get the masterbatch, and finally put the masterbatch into a plastic blown film machine to extrude and blow the film to get the finished product.

Embodiment 2

[0019] An anti-aging PE film formula of this embodiment is prepared from the following raw materials in parts by weight: 90 parts of PE, 25 parts of PS, 8 parts of trimethylolpropane triacrylate, 7 parts of sorbitol, 11 parts of phenol, and 5 parts of formaldehyde , 8 parts of caustic soda, 6 parts of plasticizer glycerin, 4 parts of thermoplastic polycarboxylate, 5 parts of zinc stearate, 6 parts of borax, 8 parts of kaolin, 4 parts of aluminate coupling agent, and 120 parts of water.

[0020] The preparation method is as follows: weigh each component according to the weight ratio, put it into the reaction kettle, heat the reaction in the nitrogen atmosphere, and then send it into the twin-screw extruder, and the twin-screw extruded sample is water-cooled, air-dried, and pelletized , to get the masterbatch, and finally put the masterbatch into a plastic blown film machine to extrude and blow the film to get the finished product.

Embodiment 3

[0022] An anti-aging PE film formula of this embodiment is prepared from the following raw materials in parts by weight: 82 parts of PE, 22 parts of PS, 6 parts of trimethylolpropane triacrylate, 4 parts of sorbitol, 7 parts of phenol, and 3 parts of formaldehyde , 5 parts of caustic soda, 3 parts of plasticizer glycerin, 1-4 parts of thermoplastic polystyrene, 3 parts of zinc stearate, 3 parts of borax, 4 parts of kaolin, 2 parts of aluminate coupling agent, and 105 parts of water.

[0023] The preparation method is as follows: weigh each component according to the weight ratio, put it into the reaction kettle, heat the reaction in the nitrogen atmosphere, and then send it into the twin-screw extruder, and the twin-screw extruded sample is water-cooled, air-dried, and pelletized , to get the masterbatch, and finally put the masterbatch into a plastic blown film machine to extrude and blow the film to get the finished product.

Abstract

The invention discloses a formula for anti-aging PE (polyethylene) thin films. The anti-aging PE thin films in the formula comprise, by weight, 80-90 parts of PE, 20-25 parts of PS (polystyrene), 5-8 parts of trimethylolpropane triacrylate, 3-7 parts of sorbitol, 6-11 parts of phenol, 2-5 parts of formaldehyde, 4-8 parts of caustic soda, 2-6 parts of plasticizer glycerin, 1-4 parts of thermoplastic polyurethane, 2-5 parts of zinc stearate, 2-6 parts of borax, 3-8 parts of kaolin, 1-4 parts of aluminum acetate coupling agents and 100-200 parts of water. The formula has the advantages that the anti-aging PE thin films are excellent in strength, toughness and anti-aging performance, processes for the anti-aging PE thin films are simple, are convenient to implement, low in raw material cost, high in production efficiency and easy to industrially implement and can be used for producing the anti-aging PE thin films by the aid of ordinary plastic film blowing machines.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an anti-aging PE film formula. Background technique [0002] The output of China's plastic film accounts for about 20% of the total output of plastic products, and it is one of the fastest growing categories of plastic products. From the application field of China's plastic film (thickness 0.06mm ~ 0.26mm), the packaging industry has the largest consumption, the most varieties and the widest application, and its consumption accounts for about 2 / 3, followed by agriculture accounting for about 30%, and then there are It is functional membrane, such as microporous membrane, shielding membrane, geomembrane and so on. If appropriate plastic additives are added to the resin matrix, various functional films required can be prepared. The production methods in the plastic film industry include calendering and extrusion. The extrusion method is divided into extrusion blown fi...
