Hot-press gas grafting hydrophobization apparatus, and eco-friendly oil-absorbing low- weight paper manufactured using same

A press-heating gas grafting hydrophobization apparatus comprising:

• an unwinder unit for continuously supplying a base material;
• a drying unit for heating a surface of the base material exposed to a hydroxyl group;
• a coating roller for coating a gas grafting reagent on the surface of the base material exposed to the hydroxyl group;
• a drying roller for evenly spreading the coated grafting reagent on the surface of the base material, the drying roller guiding the surface of the base material on which the grafting reagent is coated toward a surface of the drying roller;
• a non-air-permeable dryer belt located on an outer surface of the base material on which the gas grafting reagent is coated and surrounding the drying roller, and pressing the base material on which the gas grafting reagent is coated to the drying roller;
• a ventilator for removing hydrogen chloride generated during a gas grafting reaction;
• an air knife nozzle for removing a residual gas grafting reagent from the surface of the base material;
• and
• a rewinder unit for rewinding the base material subjected to the gas grafting reaction.
