Environment-friendly degradable polyethylene membrane material for toothpaste sheet and preparation method of environment-friendly degradable polyethylene membrane material

Abstract

The invention discloses an environment-friendly degradable polyethylene membrane material for a toothpaste sheet. The environment-friendly degradable polyethylene membrane material is prepared from the following raw materials in parts by weight: 60 to 70 parts of linear low-density polyethylene, 8 to 15 parts of wax-type corn starch, 8 to 15 parts of plant fiber powder, 3 to 6 parts of silane coupling agents, 25 to 35 parts of degradable calcium carbonate master batch, 10 to 18 parts of vinyl end capping silicone oil, 0.3 to 0.8 part of hydrogen-containing silicone oil, an appropriate amount of sulfuric acid solution and an appropriate amount of platinum catalyst. After the polyethylene membrane material is used, the polyethylene membrane material can be decomposed into water and carbon dioxide in 6 to 18 months under the natural condition, the biological degradation speed is high, no white pollution is produced, and the requirement on environment-friendliness can be met; organic silicon elastic microspheres are prepared by virtue of hydrosilylation, and degradable starch nano crystals and the plant fiber powder are adsorbed on the surfaces of the organic silicon elastic microspheres, so that the mobility and dispersibility are excellent; and meanwhile, the flexibility and the strength are excellent, and the stiffness of the membrane material is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a degradable polyethylene film material for toothpaste sheets 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-extruded film...
