Enhanced and toughened plant fiber-polyethylene composite membrane material and preparation method thereof

Abstract

The invention discloses an enhanced and toughened plant fiber-polyethylene composite membrane material. The material is prepared from, by weight, 50-60 parts of linear low-density polyethylene, 8-15 parts of waxy corn starch, 8-15 parts of plant fiber powder, 3-6 parts of stearic acid triethanolamine ester quaternary, 25-35 parts of degradable calcium carbonate master batch, 10-18 parts of vinyl-terminated silicone oil, 0.3-0.8 part of hydrogen containing silicone oil, a proper amount of sulfuric acid solution, a proper amount of platinum catalyst, 10-16 parts of straw extract fiber and 15-20 parts of towel gourd fiber. After being used, the composite membrane material can be decomposed into water and carbon dioxide under the natural conditions within 6-18 months, is high in biodegradation speed and free of white pollution, and meets the environment protection requirement; the prepared plant fiber-polyethylene composite membrane material has good stretching resistance and tear resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a reinforced and toughened plant fiber-polyethylene composite film material and a preparation method thereof. Background technique [0002] Toothpaste tube packaging currently mainly uses composite tube packaging. A very remarkable feature of the composite tube is that its tube body material is a composite sheet, and the composite sheet is a film produced by combining a variety of different materials. material compounded together. Its production process is flexible. For example, dry compounding or extrusion compounding can be used. It can be printed and compounded into a sheet to make a tube, or it can be produced into a sheet and then printed to make a tube. It has a wide range of materials, and it can be used in terms of materials. It is polyolefin, polyamide, polyester, aluminum foil, paper, etc. The type of film material can be blown film, cast film, co...
