Embodiment Construction

[0011] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0012] A composite material for polyethylene film, the composition of which is: 80% polyethylene, 10% nano-talc powder, 5% methacrylate-acrylate copolymer, and the particle size is between 1 and 4 μm. 2% light synthetic silica, 2% erucamide, 0.8% ethylene bis stearamide, 0.2% compound of antioxidant 1010 and antioxidant 168.

[0013] The preparation method is as follows: weigh each component according to the weight ratio, then add it into a high-speed mixer and stir together for 3 to 15 minutes, make it fully mixed, and then discharge the material into a twin-screw extruder to melt and extrude, and after cooling After , granulating, drying and packing, promptly obtain the present invention.

Abstract

The invention discloses a composite for a polyethylene film and a preparation method of the composite. The composite for the polyethylene film comprises the components in percentage by mass: 70%-85% of polyethylene, 3%-10% of nanometer talcum powder, 2%-8% of toughening agent, 1%-5% of anti-blocking agent, 1%-5% of slipping agent, 0.1%-1% of ethylene bis-stearamide and 0.1%-0.5% of antioxidant, and the toughening agent is one of methacrylate-acrylate copolymer, a methyl methacrylate-butadiene-styrene ternary grafted copolymer, an ethylene-vinyl acetate copolymer and an ethylene-acrylate-epoxyglycidyl ester copolymer. The composite has the beneficial effects of good antiblocking and slipping effects, good mechanical properties, strong impact toughness as well as good using effect and development prospect when being applied to the production of polyethylene film or blown film products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a composite material for polyethylene film and a preparation method thereof. Background technique [0002] Polyethylene is a thermoplastic polymer. Due to its good toughness, elongation and chemical stability, it is often used in film or blown film packaging in food, beverage and other industries. However, the smoothness of polyethylene alone is relatively poor, and some Situations require coloring to be used. Contents of the invention [0003] The object of the present invention is to provide a composite material for polyethylene film with good slippery effect and a preparation method thereof. [0004] The technical solution adopted by the present invention to solve the technical problem is: a composite material for polyethylene film, the components of which are proportioned by mass percentage: polyethylene 70%-85%, nanometer talcum powder 3%-10%, Toughening agent ...
