Abstract

The present invention discloses antibacterial, halogen-free, fire-retardant and reinforced polyethylene powder and a preparation method thereof, wherein the antibacterial, halogen-free, fire-retardant and reinforced polyethylene powder comprises, by mass, 60-80% of polyethylene, 10-15% of a halogen-free fire-retardant agent, 5-12% of alkali-free glass fibers, 2-6% of SMA, 0.5-2% of an antistatic agent, 0.5-1% of an antibacterial agent, 0.1-1% of an anti-aging agent, 0.1-1% of modified ethylene bis fatty acid amide TAF, and 0.1-0.5% of an antioxidant. The antibacterial, halogen-free, fire-retardant and reinforced polyethylene powder of the present invention has beneficial effects of good halogen-free fire-retardant property, good antistatic property, anti-bacterial function, anti-mold function, good mechanical property, stable performance, strong aging resistance, broad antibacterial spectrum, excellent electrical property, excellent heat resistance, excellent corrosion resistance, good processing fluidity, simple preparation process, and low cost so as to provide good use effects and broad prospects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial, halogen-free, flame-retardant reinforced polyethylene powder and a preparation method thereof. Background technique [0002] Polyethylene has the characteristics of light weight, non-toxicity, easy molding and processing, and high cost performance, and is widely used in many fields. However, the oxygen index of polyethylene is 17.0-17.5, which is a flammable material, which is very easy to cause fire. At the same time, polyethylene also has defects such as large molding shrinkage, insufficient antistatic performance, and low heat resistance, which limit its use in certain fields. in the application. Contents of the invention [0003] The object of the present invention is to provide an antibacterial, halogen-free, flame-retardant reinforced polyethylene powder and a preparation method thereof. [0004] The technical solution adopted by the present ...
