HOT-PRESS GAS GRAFTING HYDROPHOBIZATION APPARATUS, AND ECO-FRIENDLY OIL-ABSORBING LOW-WEIGHT PAPER MANUFACTURED USING SAME

The present invention relates to a press-heating gas grafting hydrophobization apparatus, and a hot water-resistant paper and an oil-absorbing paper manufactured using the press-heating gas grafting hydrophobization apparatus. In the press-heating gas grafting hydrophobization apparatus according to the present invention, since a non-air-permeable dryer belt is provided surrounding and pressing a drying roller to prevent dissipation from a base material of a fatty acid chloride vaporized by the drying roller, the press-heating gas grafting hydrophobization apparatus has an advantage of improving efficiency of a gas grafting reaction. Therefore, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, the reaction amount of fatty acid chloride per unit area can be remarkably improved. When the press-heating gas grafting hydrophobization apparatus according to the present invention is used, since it is possible to promote the reaction of fatty acid chloride by promoting heat conduction and inducing partial melting of a barrier coating layer such as PVA, the paper can be used as a container that can package or contain foods containing hot water and the like, and thus, it is possible to obtain an effect that the paper can replace a plastic composite material in the related art that causes environmental pollution. In addition, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, even a low-basis-weight paper that has a low basis weight or is creped and cannot be subjected to hydrophobization treatment is hydrophobized, so that it is possible to manufacture a light, economical low-basis-weight eco-friendly oil-absorbing paper.
