Embodiment 1
[0051] 1. Preparation of butyl rubber coarse compound
[0052] Waste butyl rubber to remove impurities, cut into small pieces, and set aside.
[0053] Add 50kg of waste butyl rubber cut into small pieces into a 55-liter pressurized kneader, control the temperature at about 90°C, and carry out rough mixing for about 6 minutes; then add 10kg of carbon black within 8 minutes and continue mixing refining, to obtain butyl rubber rough mix.
[0054] 2. Prepare the base layer of butyl rubber waterproof membrane
[0055] Add 15kg of butyl rubber rough mix, 12kg of 325 mesh light calcium carbonate, 0.045kg of paraffin, and 0.045kg of stearic acid into a high-speed mill with an automatic feeding device. The speed ratio of the high-speed mill is 1 : more than 1.575, the temperature is blended into a butyl rubber sheet I with a thickness of about 0.5mm at about 70°C.
[0056] Use a three-roller calender to make butyl rubber sheets I into butyl rubber waterproof membrane bases of differ...
Embodiment 2
[0063] 1. Preparation of butyl rubber coarse compound
[0064] Waste butyl rubber to remove impurities, cut into small pieces, and set aside.
[0065] Add 45kg of waste butyl rubber cut into small pieces into a 55-liter pressurized kneader, control the temperature at about 90°C, and carry out rough mixing for about 6 minutes; then add 8kg of carbon black within 8 minutes and continue mixing refining, to obtain butyl rubber rough mix.
[0066] 2. Prepare the base layer of butyl rubber waterproof membrane
[0067] Add 19kg of butyl rubber rough mix, 17kg of 325 mesh light calcium carbonate, 0.04kg of paraffin, and 0.06kg of stearic acid into a high-speed mill with an automatic feeding device. The speed ratio of the high-speed mill is 1 : Above 1.575, the temperature is blended into butyl rubber sheet I at about 75°C.
[0068] Use a three-roller calender to make butyl rubber sheets I into butyl rubber waterproof membrane bases of different thicknesses, with a line speed of 17-...
