Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of nano-particles filled modified polyethylene material and preparation method thereof.
Background technology
Polyethylene, due to light weight, nontoxic, has excellent dielectric properties, chemical stability and the advantage such as anticorrosive, and cheap, and forming process is easy, has been widely used in the fields such as electrical equipment, chemical industry, food, machinery, packaging at present.But pure polyethylene exists the shortcomings such as impelling strength deficiency, easy firing, therefore, in order to improve performance, usually need to carry out necessary modification to it before polyethylene uses.Along with the popularity of nanotechnology, nano material is considered to 21 century the most promising material, and the research boom that become international, therefore prepare a kind of nano-particles filled modified polyethylene material and there is good application prospect.
Summary of the invention
The object of the present invention is to provide a kind of nano-particles filled modified polyethylene material with excellent mechanical performances and toughness and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of nano-particles filled modified polyethylene material, and its component by mass percent proportioning is: polyvinyl resin 50% ~ 80%, nano inoganic particle 5% ~ 25%, calcium stearate 0.1% ~ 0.5%, fire retardant 12% ~ 18%, ethylene bis stearic amide 0.2% ~ 1.5%, 1010 oxidation inhibitor 0.1% ~ 0.5%, 168 oxidation inhibitor 0.1% ~ 0.5%.
One in the water-ground limestone that described nano inoganic particle is particle diameter between 10nm ~ 20 μm, aerosil, talcum powder, calcium oxide, aluminium hydroxide, magnesium hydroxide.
Described fire retardant is brominated polycarbonate oligomer class environmental protection fire retarding agent BC-58.
The preparation method of a kind of nano-particles filled modified polyethylene material of the present invention is: after nano inoganic particle and calcium stearate being taken by weight ratio, add in sonic oscillation producer or high-speed mixer, stir 20 ~ 60 minutes at 100 DEG C ~ 150 DEG C temperature, make dispersed, then be cooled to lower than 40 DEG C, add the polyvinyl resin taken by weight ratio again, fire retardant, ethylene bis stearic amide, 1010 oxidation inhibitor and 168 oxidation inhibitor, continue mixing 5 ~ 15 minutes, discharging is extruded after adding twin screw extruder melt blending, granulation, namely the present invention is obtained.
The invention has the beneficial effects as follows, the present invention adopt nano inoganic particle and polyvinyl resin blended, and add appropriate calcium stearate, fire retardant and other auxiliary agent, substantially increase intensity, rigidity, thermotolerance and stability, there is good toughness reinforcing, the effect that strengthens and keep better mechanical property, and good flame retardation effect, cost is low, the simple and easy handling of preparation technology.
