Wooden-Inorganic laminated floor panel improving flame retardation and thermal conductivity and Method of the same

The present invention is a wood-inorganic laminated flooring material capable of preventing the phenomenon that the inorganic board of the tip part is broken or broken due to impact during construction by forming a timber layer on both surface layers of the inorganic board， which is the tongue part of the flooring material， and It relates to a method of manufacturing the same. The wood-inorganic laminate flooring material of the present invention complements the disadvantages of inorganic boards (bending strength， water resistance， impact strength， heat insulation， sound-absorbing properties) by bonding wood to both sides of an inorganic board (magnesium board) or by stacking an inorganic board between wood It can increase the dimensional stability of wood. In addition， according to the present invention， as the inorganic board is used， thermal conductivity and heating efficiency can be increased compared to a wood-based flooring material using solid wood or plywood. In addition， the present invention can prevent the phenomenon that the inorganic board of the touch part is broken or broken due to the impact during construction by forming a timber layer on both surface layers of the inorganic board which is the tongue part of the flooring material.
