Embodiment 1
[0026] Preparation of main stabilizer;
[0027] a) Add 0.05 mol of stearic acid and 0.05 mol of benzoic acid into a 1000 ml three-necked flask, heat up to 70° C. until completely melted.
[0028] b) Dissolve 0.1 mol of sodium hydroxide (slightly excessive) in a 100ml beaker, add dropwise to a three-necked flask with a dropping funnel, drop it in ten minutes, and maintain the reaction for half an hour.
[0029] c) Raise the temperature to 85°C, then weigh 0.025 mol of zinc sulfate heptahydrate and 0.025 mol of calcium chloride into a 50ml beaker to dissolve completely, add zinc sulfate and calcium chloride at the same time with a dropping funnel, and drop them in half an hour , and maintain the reaction for 1 hour.
[0030] e) The product was washed with water, suction filtered, and dried in an oven at 80° C. for 12 hours until constant weight.
Embodiment 2
[0032] Preparation of primary stabilizer:
[0033] a) Add 0.05 mol of stearic acid and 0.05 mol of benzoic acid into a 1000 ml three-necked flask, heat up to 80-90° C. until completely melted.
[0034] b) Dissolve 0.1 mol of sodium hydroxide (slightly excessive) in a 100ml beaker, add dropwise to a three-neck flask with a dropping funnel, drop it in ten minutes, and maintain the reaction for half an hour.
[0035] c) The temperature is raised to 95° C., and then the zinc chloride of 0.025 mol is weighed to be completely dissolved and firstly added to the flask with a dropping funnel, then 0.025 mol of calcium chloride is weighed and added to a 50 ml beaker to completely dissolve, and then added respectively with the dropping funnel, Dropping finished in half an hour, and finally maintained the reaction for 1 hour.
[0036] e) The product was washed with water, suction filtered, and dried in an oven at 80° C. for 12 hours until constant weight.
Embodiment 3
[0038] Preparation of primary stabilizer:
[0039] a) Add 0.05 mol of stearic acid and 0.1 mol of benzoic acid into a 1000 ml three-necked flask, heat up to 80-90° C. until completely melted.
[0040] b) Dissolve 0.15 mol of sodium hydroxide (slightly excessive) in a 100 ml beaker, add it into a three-necked flask with a dropping funnel, drop it in ten minutes, and maintain the reaction for half an hour.
[0041] c) Raise the temperature to 95°C, then weigh 0.03 mol of calcium chloride to dissolve completely and add it to the flask first with a dropping funnel, then weigh 0.03 mol of zinc sulfate heptahydrate and add it to a 50ml beaker to dissolve completely, then add it separately with a dropping funnel , respectively controlled for half an hour to finish dripping, and finally maintained the reaction for 1 hour.
[0042] e) The product was washed with water, suction filtered, and dried in an oven at 80° C. for 12 hours until constant weight.
