Problems solved by technology

However, as mentioned above, because the calibrator 4 must be positioned adjacent to the die, there are limitations on the diameter and circumferential length of the embossing rolls disposed therebetween.
Therefore, the repetition period of the pattern repeatedly formed on the surface of the profile becomes short and thus its patternability is deteriorated

Embodiment Construction

[0034] Next, embodiments of the present invention will be described in detail.

[0035] figure 2 is a schematic diagram of an apparatus for manufacturing window frame profiles according to an embodiment of the present invention. refer to figure 2 , if pellets or composite materials of thermoplastic resins such as polystyrene (PS), polyethylene (PE), polypropylene (PS), polyvinyl chloride (PVC) and ABS resin are injected into the main extruder 10 through the hopper 2 , the material is heated by a heater arranged in the main extruder 10 to be melted into a gel state and conveyed by the rotation of the extrusion screw. Thereafter, the profile P having the desired shape is extruded through the die 30 arranged on the front side of the main extruder 10, and passes through the calibrator 70, 80 and the cooling device 90, and then passes through the pulling device 99 and the cutting machine, the pulling device 99 and the cutting machine are similar to the prior art and thus a det...

Abstract

Disclosed is a window profile provided with a skin layer which a co-extrusion resin composition is dual-extruded on one surface of a profile extruded from a main extruder, wherein the co-extrusion resin composition contains wood fiber. The co-extrusion resin composition comprises a first raw material for forming a base color, a second raw material for forming a mid-tone color, and a third raw material for forming a high-tone color. According to the present invention as described above, the skin layer is integrally formed with one side of the profile by the co-extrusion, and thus it is possible to provide the texture of natural wood and thus a luxurious atmosphere. Further, in the window profile, various colors can be naturally expressed on the skin layer of the window profile so as to be distinguished from each other, the embo-patterns are formed into two steps, the repetition period of the patterns becomes long and the like, and thus it is possible to provide the graphicness similar to natural wood.

Description

technical field [0001] The present invention relates to a method for manufacturing a window frame profile with natural wood texture by co-extrusion technology and the window frame profile produced by the method, and in particular to a window frame profile in which a resin composition containing wood fibers It is double-stage extruded on one side and provided with embossing thereon, providing a pattern with a natural wood grain. Background technique [0002] In the extrusion process for manufacturing conventional window frame profiles, such as figure 1 As shown, if a pellet or composite type material of thermoplastic resin is injected into the extruder 1 through the hopper 2, the material is heated by a heater arranged in the heating cylinder of the extruder 1 so as to be melted into a gel state, passed through the extruder The rotation of the screw is conveyed and then extruded by a die 3 arranged at the front end of the extruder 1 . Also extruded through the die 3 so that...
