Embodiment 1

[0015] It is prepared from the following raw materials in parts by weight, ethylene: octene-1: polyisobutene: straw: 2,2-dimethylbenzyl diphenylamine: VCI = 170: 63: 52: 69: 22: 19 .

[0016] The preparation process of the present invention is as follows:

[0017] Heating: Mix the above-mentioned raw materials according to the above-mentioned weight ratio, then raise the temperature to 250°C-280°C to form a melt;

[0018] Extrusion: Extrude the above-mentioned heated raw materials;

[0019] Casting: the above-mentioned extruded raw materials are casted, and then cooled by chilling rolls. The temperature of the casting cooling rolls is controlled at 20°C to 30°C, and the winding tension is within 10kg.

Embodiment 2

[0021] It is prepared from the following raw materials in parts by weight, ethylene: octene-1: polyisobutene: straw: 2,2-dimethylbenzyl diphenylamine: VCI = 130: 40: 30: 54: 13: 10 .

[0022] Its preparation process is with embodiment 1.

Embodiment 3

[0024] It is prepared from the following raw materials in parts by weight, ethylene: octene-1: polyisobutene: straw: 2,2-dimethylbenzyl diphenylamine: VCI = 220: 110: 80: 99: 48: 45 .

[0025] Its preparation process is with embodiment 1.

Abstract

The invention relates to a stretch film and a preparation process thereof, which can be widely used in the fields of full-container packaging and warehousing of hardware, mineral products, chemical products, medicine, foods, machinery and other products. The stretch film is prepared from ethylene, octylene-1, polyisobutene, straws, 2,2-dimethylbenzyl diphenylamine and volatile corrosion inhibitor (VCI) in parts by weight, has the advantages of high toughness, high elasticity, tear resistance, high viscosity, low thickness, cold resistance, heat resistance, pressure resistance, dust prevention, water prevention, single-side adhesion, double-side adhesion and the like, and can save materials, labor and time during use.

Description

technical field [0001] The invention relates to a stretch film, in particular to a stretch stretch film and a preparation process thereof, which are widely used in the packaging and warehouse storage fields of hardware, minerals, chemicals, medicine, food, machinery and other products. Background technique [0002] Stretch film, also known as stretch film and heat shrinkable film, was the first in China to produce PVC stretch film with PVC as the base material and DOA as the plasticizer and self-adhesive function. Due to environmental protection issues, high cost, poor stretchability and other reasons, it has been gradually eliminated. Stretch film must have two most basic properties, one necessary condition is to have good mechanical strength, better extensibility and good resilience; another necessary condition is that its surface (single side or double side) must be Has strong viscosity. Polyethylene can produce films with good mechanical strength, good elongation and g...
