Abstract

The invention provides a high-strength and high-toughness stretching and winding membrane and a preparation method thereof. The preparation method comprises the following steps: (1) sufficiently heating and stirring low-density polyethylene, linear low-density polyethylene, polyisobutene, silicon dioxide, light calcium carbonate, zinc stearate, an antioxidant 1010, polyethylene glycol, nano zinc oxide powder and titanium nitride; (2) continually raising the temperature, and adding epoxidized soybean oil, epoxidized soybean oil-phenolic aldehyde-benzoxazine ternary copymerized and modified phenolic resin and bismaleimide modified cyanate resin; then sufficiently stirring and carrying out heat insulation; (3) carrying out double-screw high-temperature extrusion on a stretching and winding membrane material of step (2); (4) finally, carrying out casting and membrane formation by adopting a casting machine; casting to obtain the stretching and winding membrane material. The high-strength and high-toughness stretching and winding membrane provided by the invention has very high tearing strength and has excellent tensile strength and good toughness.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a high-strength and high-toughness stretch wrapping film and a preparation method thereof. Background technique [0002] Polyethylene (PE) stretch wrapping film is considered to be an important development direction of film production in the future due to its high production efficiency, good environmental adaptability and high product quality. PE stretch wrapping film is mainly used in various packaging films. It has the characteristics of being suitable for large-volume packaging, renewable, safe, and fast. It has been widely used. my country began to develop PE stretch wrapping film in the late 1980s, and was widely used in the early 1990s, and has developed rapidly in recent years. Industrial packaging film is the largest use of PE stretch wrapping film, and its consumption accounts for more than 50% of the total consumption. At present, my country's annual economic losses...
