Abstract

The invention relates to a pickleball rotationally molded polyethylene composite material and a preparation method thereof, in particular to a pickleball rotationally molded polyethylene composite material. The raw material formula is: 38.34‑93.5% polyethylene, 6.28‑93.5% polyolefin elastomer 60.4%, 0.12-0.66% of antioxidant and 0.10-0.60% of anti-ultraviolet agent, and then through mixing, melt blending, extrusion granulation and milling to obtain the pickle ball rotationally molded polyethylene composite material. A method for preparing the material is also provided. The polyethylene composite material for rotational molding of the pickleball obtained by the invention can be used for rotational molding of the pickleball, and the pickleball can resist hitting for 3000 times.

Description

technical field [0001] The invention relates to a polyethylene-polyolefin elastomer composite material for rotomolding a pickleball, in particular to a polyethylene material which is resistant to hitting a pickleball for 3000 times and is suitable for a rotomolding production process and a preparation method thereof. [0002] technical background [0003] Rotational molding is a plastic processing method that uses a rotating mold for processing. The processing process is to put plastic powder or slurry into the mold, and the closed mold is rotated or shaken on the equipment, and the mold is heated by an open flame or hot air. External heating, the plastic powder or slurry is turned and flowed inside the mold under the heated state. After the temperature reaches the softening point, it is gradually coated on the inner surface of the mold, melted and condensed. The mold is placed in the natural environment or passed through water, After cooling by media such as fog and wind, th...
