Embodiment 1
[0033] A kind of preparation method of environment-friendly rubber vulcanization activator, concrete steps are as follows:
[0034] Step 1: Grind 3.4kg fatty acid glycerides, 3.5kg glycerin, 2.03kg zinc oxide evenly and add 0.16kg salicylic acid catalyst into the reaction kettle, set the reaction temperature to 220°C, react for 4 hours, and stir at a rate of 120r / min; During the reaction time, filter while hot, wash 3 times with isopropanol, and dry at 80°C for 10 hours;
[0035] Step 2: Mix 0.66kg isooctanoic acid, 0.69kg lauric acid, 0.35kg myristic acid, 0.45kg palmitic acid, 0.45kg stearic acid and 0.56kg zinc oxide and add them to another reaction kettle. Hydrogen oxide is used as a catalyst, the reaction temperature is set at 135°C, the stirring speed is 300r / min, and the reaction time is 90min. After the reaction is completed, it is cooled and solidified;
[0036] Step 3: After the two products of step 1 and step 2 are pulverized by a pulverizer and mixed evenly, the r...
Embodiment 2
[0038] A kind of preparation method of environment-friendly rubber vulcanization activator, concrete steps are as follows:
[0039] Step 1: Grind 3.4kg fatty acid glycerides, 2.97kg glycerin, 2.63kg zinc oxide evenly and add 0.14kg salicylic acid catalyst into the reaction kettle, set the reaction temperature to 220°C, react for 4 hours, and stir at a rate of 120r / min; During the reaction time, filter while hot, wash 3 times with isopropanol, and dry at 80°C for 10 hours;
[0040] Step 2: Mix 0.66kg isooctanoic acid, 1.3kg lauric acid, 0.79kg myristic acid, 0.35kg palmitic acid, 0.35kg stearic acid and 0.74kg zinc oxide and add them to another reaction kettle. Hydrogen oxide is used as a catalyst, the reaction temperature is set at 135°C, the stirring speed is 300r / min, and the reaction time is 90min. After the reaction is completed, it is cooled and solidified;
[0041]Step 3: After the two products of step 1 and step 2 are pulverized by a pulverizer and mixed evenly, the ru...
Embodiment 3
[0043] A kind of preparation method of environment-friendly rubber vulcanization activator, concrete steps are as follows:
[0044] Step 1: Grind 3.4kg fatty acid glycerides, 4.1kg pentaerythritol, 1.7kg zinc oxide evenly and add 0.14kg salicylic acid catalyst into the reaction kettle, set the reaction temperature to 220°C, react for 4 hours, and stir at a rate of 120r / min; During the reaction time, filter while hot, wash 3 times with isopropanol, and dry at 80°C for 10 hours;
[0045] Step 2: Mix 0.66kg isooctanoic acid, 0.69kg lauric acid, 0.35kg myristic acid, 0.45kg palmitic acid, 0.45kg stearic acid and 0.56kg zinc oxide and add them to another reaction kettle. Hydrogen oxide is used as a catalyst, the reaction temperature is set at 135°C, the stirring speed is 300r / min, and the reaction time is 90min. After the reaction is completed, it is cooled and solidified;
[0046] Step 3: After the two products of step 1 and step 2 are pulverized by a pulverizer and mixed evenly,...
