Environment-friendly degradable-type halloysite nano-tubes/polyethylene film material and preparation method of same

Abstract

The invention discloses an environment-friendly degradable-type halloysite nano-tubes / polyethylene film material which is composed of, by weight, 60-70 parts of linear low-density polyethylene, 8-15 parts of waxy corn starch, 8-15 parts of plant fiber powder, 3-6 parts of a silane coupling agent, 25-35 parts of a degradable calcium carbonate master batch, 10-18 parts of vinyl-terminated silicon oil, 0.3-0.8 parts of hydrogen-containing silicon oil, a proper amount of a sulfuric acid solution, a proper amount of a platinum catalyst, 10-15 parts of halloysite nano-tubes, 8-12 parts of white carbon black, and a proper amount of anhydrous ethanol. The polyethylene film material, after use, can be naturally decomposed into water and CO2 within 6-18 months, is high in biodegradation speed without generation of white pollution, and satisfies environment protection demand. The white carbon black and the modified halloysite have cooperative effects to form a special dual-filler net structure, so that the film material is significantly improved in tensile strength, stiffness and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an environment-friendly degradable halloysite nanotube-polyethylene 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 fi...
