Embodiment 1
[0029] 50 kilograms of polysulfide silanes, 30 kilograms of carbon black and 20 kilograms of organic ethers are processed through the following steps:
[0030] Add 20 kg of carbon black into the high-speed mixer, then slowly add the remaining polysulfide silane and carbon black in the form of spray, then add organic ether, and gradually raise the temperature to 70-75°C, react for 20-30min, and continue Stir, then raise the temperature to 90-95°C, maintain the reaction process for 40-60min, then cool down and take out the product;
[0031] (3) extruding and granulating the product obtained in (2) at 45-50° C. using a twin-screw extruder to obtain modified coupling agent masterbatches. It was then used in the manufacture of rubber technology, and the specific test results are shown in Table 1.
Embodiment 2
[0033] 45 kilograms of polysulfide silanes, 35 kilograms of carbon black and 20 kilograms of organic ethers are processed through the following steps:
[0034] Add 20 kg of carbon black into the high-speed mixer, then slowly add the remaining polysulfide silane and carbon black in the form of spray, then add organic ether, and gradually raise the temperature to 70-75°C, react for 20-30min, and continue Stir, then raise the temperature to 90-95°C, maintain the reaction process for 40-60min, then cool down and take out the product;
[0035] (3) extruding and granulating the product obtained in (2) at 45-50° C. using a twin-screw extruder to obtain modified coupling agent masterbatches. It was then used in the manufacture of rubber technology, and the specific test results are shown in Table 1.
Embodiment 3
[0037] 40 kilograms of polysulfide silanes, 40 kilograms of carbon black and 20 kilograms of organic ethers are processed through the following steps:
[0038] Add 20 kg of carbon black into the high-speed mixer, then slowly add the remaining polysulfide silane and carbon black in the form of spray, then add organic ether, and gradually raise the temperature to 70-75°C, react for 20-30min, and continue Stir, then raise the temperature to 90-95°C, maintain the reaction process for 40-60min, then cool down and take out the product;
[0039] (3) extruding and granulating the product obtained in (2) at 45-50° C. using a twin-screw extruder to obtain modified coupling agent masterbatches. It was then used in the manufacture of rubber technology, and the specific test results are shown in Table 1.
