Example Embodiment
[0024] Example 1
[0025] Add 100 grams of succinic acid and 2 grams of octadecanoic acid, blow in nitrogen, mix uniformly with mechanical stirring, heat up to 188℃, keep mechanical stirring, and add 60 grams of 1-hydroxymethyl-2 dropwise uniformly in 22 minutes -Hydroxy-ethane sulfonate potassium, then the temperature is raised to 198℃, 1.5 g of ethylene glycol antimony is added, and 150 g of pentanediol are added dropwise uniformly within 40 minutes. After the addition of pentanediol, the temperature is raised to 208℃ to continue the reaction 20 min, reduce the temperature to 194°C, add 5 g carboxylated nitrile rubber, 3 g water-based tackifying resin, 2 g paraffin, 4 g talc, 0.5 g propyl gallate, mix and stir for 10 min, cool, and package.
