Embodiment 1
[0027] Weigh the reactant whose molar ratio of dipentaerythritol and lauric acid is 1:1.1, put it into a three-necked flask for mixing, stir while heating, and after the temperature rises to 130°C, add p-toluenesulfonic acid and toluene in turn, The amount of toluenesulfonic acid added is 0.18% of the total mass of the reactants, the amount of toluene added is 10% of the total mass of the reactants, and the reaction is carried out at a constant temperature of 130°C for 3 hours. No water is generated in the water separator, and then the temperature is lowered to 90°C, and the Zinc oxide with a total mass of 15% of the reactants, stirred at 90°C for 1.5 hours, then the reaction was terminated, the residual water-carrying agent and water were distilled off under reduced pressure, and the product was vacuum-dried, and the obtained white solid was pulverized to become the heat stabilizer .
[0028] Calculated in parts by mass, weigh 100 parts of PVC, add 4 parts of zinc-based penta...
Embodiment 2
[0030] Weigh the reactant with the ratio of dipentaerythritol and myristic acid as 1:2.1, put it into a three-necked flask and mix it, stir while heating. After the temperature rises to 140°C, add phosphoric acid, toluene, phosphoric acid The addition amount of toluene is 0.35% of the total mass of the reactants, the addition of toluene is 15% of the total mass of the reactants, the constant temperature reaction is carried out at 140°C for 2h, no water is generated in the water separator, then the temperature is lowered to 100°C, and the total 20% by mass of barium oxide, stirred at 100°C for 1.5 hours to complete the reaction, distilled off the remaining water-carrying agent and water under reduced pressure, and vacuum-dried the product. The obtained white solid was pulverized and became the thermal stabilizer.
[0031] Calculated in parts by mass, weigh 100 parts of PVC, add 4 parts of barium pentaerythritol ester prepared above, 2.4 parts of calcium stearate, 1 part of epoxi...
Embodiment 3
[0033]Weigh the reactant raw materials with the mass ratio of dipentaerythritol, palmitic acid and stearic acid as 1:1.1:1.1, add them into a three-necked flask and mix them, stir while heating, after the temperature rises to 170°C, add the Toluenesulfonic acid and toluene, the addition of p-toluenesulfonic acid is 0.3% of the total mass of reactants, the addition of toluene is 5% of the total mass of reactants, constant temperature reaction at 170 ° C for 1.5h, no water is generated in the water separator , then lowered the temperature to 110°C, added magnesia with 35% of the total mass of reactants, stirred at 110°C for 3 hours, and then ended the reaction, distilled off the remaining water-carrying agent and water under reduced pressure, and dried the product in vacuum, and the obtained white solid was crushed. For the heat stabilizer.
[0034] Calculated in parts by mass, weigh 100 parts of PVC, add 4 parts of magnesium-based pentaerythritol ester prepared above, 2.4 parts...
