| titleOfInvention | Door frame and method for manufacturing the same |
| abstract | The door frame material according to the present invention comprises a door frame material core material; And a PVC coating layer coated on the door frame material. At this time, the PVC coating layer may be formed to have a constant thickness. The door frame core material may be formed in a square shape of wood, and the thickness of the PVC coating layer may be different in the longitudinal direction and the width direction. A method for manufacturing a door frame material having a warp preventing function according to another aspect of the present invention includes the steps of: mixing a PVC, a stabilizer, a flame retardant, and a foaming agent at 110 to 130 캜 for 20 to 30 minutes to form a mixture; Cooling the mixture at 20-80 < 0 >C; Inserting the cooled mixture into an extruder; Fusing the inserted mixture in a cylinder at 150 to 240 캜; Inserting a door frame core material into a mold to form a PVC coating layer with the melted mixture; And cooling the door frame core material having the PVC coating layer formed thereon. Accordingly, the present invention provides a door frame material having a beautiful appearance while preventing twisting and bending of the wood frame material. |
