Abstract
The invention discloses a gangue-filled polyethylene film material for toothpaste sheeting, made from the following materials according to parts 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 degradable calcium carbonate master batch, 10-18 parts of vinyl-terminated silicone oil, 0.3-0.8 part of hydrogen-containing silicone oil, suitable sulfuric acid solution, suitable platinum catalyst, 5-10 parts of maleic anhydride-grafted polypropylene, 6-12 parts of white oil and 15-20 parts of gangue. After using, the polyethylene film material of the invention can be degraded into water and carbon dioxide under natural conditions within 6-18 months, the biodegradation speed is high, and the requirement for environmental protection is met; The maleic anhydride-grafted polypropylene can be used to provide effectively improved and adjusted dispersion of gangue powder in polyethylene composite material, thus reducing the influence of the defects such as aggregation and pores upon a film blowing process.
Description
technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyethylene film material filled with coal gangue 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-...
