Abstract

The invention discloses a method for preparing an inorganic nanoparticle / polyethylene copolymer composite material. The method comprises the following steps: performing oleophylic modification treatment on calcium carbonate, zinc oxide, aluminum oxide, titanium dioxide and silicon dioxide inorganic nanoparticles, performing blending dispersion on a copolymer of modified inorganic nanoparticles and an ethylene-vinyl acetate copolymer in an internal mixer at 100-130 DEG C, adding aids at 120-160 DEG C, performing melting and blending so as to cross-link polyethylene and inorganic nanoparticles / ethylene-vinyl acetate copolymer, granulating, and processing, thereby obtaining living or production articles. The oxygen index of the inorganic nanoparticle / polyethylene copolymer composite material disclosed by the invention is approximate to 30%. The inorganic / organic nano composite material disclosed by the invention is excellent in machinability, good in flame retardancy, good in antibacterial property, good in tensile and impact resistance and applicable to processing of tubes, films, daily articles and the like which are closely associated with living.

Description

technical field [0001] The invention relates to a preparation method of a novel highly flame-retardant and antibacterial polyethylene copolymer composite material, in particular to a preparation method of an inorganic nanoparticle / polyethylene copolymer composite material. Background technique [0002] Polyethylene and ethylene-vinyl acetate copolymerized polymer materials are used to prepare plastic bags, agricultural films, pipes, wires and cables, etc. But polyethylene resin is flammable, and its oxygen index is 17.4%, and the oxygen index of ethylene-vinyl acetate copolymer is about 20.6%; In addition, the weather resistance is not good, it is easy to age, and it is easily damaged at low temperature, so it limits its use. Applications, and require modification to improve flame retardancy, stability and mechanical strength. [0003] In order to improve the flame retardancy, stability and mechanical strength of polyethylene and ethylene-vinyl acetate copolymerized polymer...
