Embodiment 1
[0048] Measure 80 parts of metallocene polyethylene, 10 parts of EVA resin, 0.2 parts of antioxidant, 2 parts of carbon black, and 7 parts of reinforcing agent with a metering device, add them to the plastic mixer after metering, and start stirring . The stirring time is 3min to prepare the base material, and then the base material is added to the hopper of the extruder, preheated by the extruder, and the plasticizing temperature is: zone 1: 170°C~180°C, zone 2: 180°C~ 190°C, Zone 3: 190°C-200°C, Zone 4: 190°C-200°C, Zone 5: 180°C-190°C. The heating and preheating time should not be less than 2.5 hours, and the metallocene polyethylene waterproof sheet is obtained through extruder extruding, three-roller calendering, compounding seven-layer co-extruded isolation film, cooling and setting, and then traction and curling;
[0049]Then, 30 parts of asphalt 90#, SBS: 8 parts, SBR: 10 parts, aromatic oil: 20 parts, light calcium: 30 parts, rosin: 2 parts, are stirred in a mixing ta...
Embodiment 2
[0051] Measure 70 parts of metallocene polyethylene, 17 parts of EVA resin, 0.3 parts of antioxidant, 2.5 parts of carbon black, and 10 parts of reinforcing agent with a metering device, add them to the plastic mixer after metering, and start stirring . The stirring time is 3min to prepare the base material, and then the base material is added to the hopper of the extruder, preheated by the extruder, and the plasticizing temperature is: zone 1: 170°C~180°C, zone 2: 180°C~ 190°C, Zone 3: 190°C-200°C, Zone 4: 190°C-200°C, Zone 5: 180°C-190°C. The heating and preheating time should not be less than 2.5 hours, and the metallocene polyethylene waterproof sheet is obtained by extruding through an extruder, calendering with a three-roller machine, compounding a seven-layer co-extruded isolation film, cooling and setting, and then pulling and curling.
[0052] Then 35 parts of asphalt 90#, SBS: 7 parts, SBR: 9 parts, aromatic oil: 15 parts, light calcium: 25 parts, rosin 3 parts, are...
Embodiment 3
[0054] Measure 72 parts of metallocene polyethylene, 20 parts of EVA resin, 0.2 parts of antioxidant, 3 parts of carbon black, and 5 parts of reinforcing agent with a metering device, add them to the plastic mixer after metering, and start stirring . The mixing time is 4min to prepare the base material, and then the base material is added to the hopper of the extruder, preheated by the extruder, and the plasticizing temperature is: zone 1: 170 ° C ~ 180 ° C, zone 2: 180 ° C ~ 190°C, Zone 3: 190°C-200°C, Zone 4: 190°C-200°C, Zone 5: 180°C-190°C. The heating and preheating time should not be less than 2.5 hours, and the metallocene polyethylene waterproof sheet is obtained by extruding through an extruder, calendering with a three-roller machine, compounding a seven-layer co-extruded isolation film, cooling and setting, and then pulling and curling.
[0055] Then, 40 parts of asphalt 90#, SBS: 6 parts, SBR: 8 parts, aromatic oil: 25 parts, light calcium: 20 parts, are stirred i...
