Embodiment 1
[0016] 1. Mix 98kg of polyethylene recycled material resin with 2kg of dicumyl peroxide, add it into the hopper of the reactive twin-screw unit, and heat it to make the molten material generate chain initiation in the barrel;
[0017] 2. Add 1.5kg of vinyl silane to the fourth section of the barrel of the unit;
[0018] 3. Add 0.15kg of free radical scavenger and 0.4kg of quencher to the sixth section of the barrel of the unit for reaction;
[0019] 4. After the material has completed the reaction, it passes through the splitter plate and the filter screen, and uses a 120-mesh steel screen to filter out impurities, extrudes through the die head, and is pulled into a strip;
[0020] 5. After the strips are introduced into the cooling water tank to cool, they are sent to the pelletizer to be cut into pellets.
Embodiment 2
[0022] 1. Mix 99kg of polyethylene recycled material resin with 1kg of dicumyl peroxide, add it into the hopper of the reactive twin-screw unit, and heat it to make the molten material generate chain initiation in the barrel;
[0023] 2. Add 1kg of vinyl silane to the fourth section of the barrel of the unit;
[0024] 3. Add 0.25kg of free radical scavenger and 0.2kg of quencher to the sixth section of the barrel of the unit for reaction;
[0025] 4. After the material has completed the reaction, it passes through the splitter plate and the filter screen, and uses a 120-mesh steel screen to filter out impurities, extrudes through the die head, and is pulled into a strip;
[0026] 5. After the strips are introduced into the cooling water tank to cool, they are sent to the pelletizer to be cut into pellets.
