Provided by the present invention is a board which uses paper sludge to which soluble adhesive of 4-20 wt%, a waterproof agent of 8-12 wt%, a wallastonite (CaSiO_3) of 2-4 wt%, cement of 1-3 wt%, calcium oxide powder of 1-2 wt%, calcium chloride powder of 1-2 wt%, and an antifungal agent of 0.01~0.1 wt% are respectively added about paper sludge of 100 wt% having a water content percentage of 65-75%. The present invention: recycles paper sludge which is disposed in the method of an ocean dumping, an incineration, a landfill, etc. by producing the board having the paper sludge as a main raw material; does not have an economic burden which is caused by an incineration and a landfill while preventing the pollution of ocean and land from the incineration and the landfill; and not only is widely used for building interiors and exteriors, a lightweight partition, and an interior material by having excellent appearance, strength, and lightweight but also obtains the board using the paper sludge with excellent thermal resistance and smoke tolerance. |
