Embodiment 1
[0016] Embodiment 1: take by weighing active zinc oxide and pentaerythritol powder 121.5g and 136.0g respectively and add in the high-speed mixer and mix, wherein the rotating speed of the high-speed mixer is 1500r / min, after mixing for 5 minutes, place a three-necked flask, and the reaction temperature setting: 140°C, vacuum degree: -100KPa, react for 60min, and stir at 1000r / min. After the reaction, cool the product to room temperature and pulverize it with an ultrafine pulverizer to obtain zinc pentaerythritol C.
