Description
본 발명은 목분을 함유한 합성목재수지 재질의 문틀 제조방법에 관한 것이다.The present invention relates to a method for producing a door frame made of synthetic wood resin material containing wood powder.
종래에는 나무문틀을 대체하는 것으로 주로 폴리염화비닐(PVC)과 목분을 혼합한 수지 또는 PVC 단독 수지를 이용하여 문틀을 제작하여 왔다. 공개특허공보 제2000-40866호는 표면을 물성증강제로 처리한 목분을 PVC 수지에 첨가하여 합성목재를 제조하는 방법에 관하여 개시하고 있다. 그러나, PVC는 화재시 인체에 유해한 유독가스가 발생하고, 환경호르몬을 방출하는 문제가 있다.Conventionally, the door frame has been manufactured using a resin obtained by mixing polyvinyl chloride (PVC) and wood powder or a PVC sole resin. Korean Patent Laid-Open Publication No. 2000-40866 discloses a method for producing a synthetic wood by adding wood powder treated with a physical property enhancer to a PVC resin. However, PVC has a problem in that toxic gases are harmful to the human body in the event of fire and release environmental hormones.
뿐만 아니라, 종래 목분을 함유한 PVC 수지를 이용하여 문틀을 제조하는 데에는 목분 함유 PVC 수지를 압출한 후, 일측에 강도를 보강하는 보강목재를 부착시키고, 무늬목 시트를 입히는 래핑(wrapping) 작업을 수행하여야 하였다. 따라서, 공정이 복잡하고 시간이 많이 소요되었다. 또한, 종래의 목분 함유 PVC 수지 문틀은 기온이 아주 낮거나 아주 높을 때 수축, 팽창 현상이 일어나는데 수지 부분과 보강목재 부분의 수축, 팽창률이 달라 시공, 유지에 어려움이 있었다.In addition, to manufacture a door frame using a conventional PVC resin containing wood powder, extrude the wood powder containing PVC resin, attach a reinforcing wood to strengthen the strength on one side, and performs a lapping (wrapping) coating the veneer sheet Should be. Thus, the process was complicated and time consuming. In addition, the conventional wood powder-containing PVC resin door frame shrinkage, expansion phenomenon occurs when the temperature is very low or very high, the contraction, expansion rate of the resin part and reinforcement wood part is difficult to install and maintain.
또한, 종래 PVC 수지 문틀은 높은 온도에서 제조하여야 하므로 목분과 PVC 수지를 혼합 압출한 후 수냉방식으로 급속히 냉각하게 되므로 이 과정에서 수분이 수지 내로 침투하여 사용 중 곰팡이가 발생하는 등 미관상, 위생상의 문제점이 있었다.In addition, conventional PVC resin door frame has to be manufactured at a high temperature, so after mixing and extruding wood powder and PVC resin, it is rapidly cooled by water-cooling method, so water penetrates into the resin in this process and mold occurs during use. There was this.
따라서, 본 발명의 목적은 종래 기술의 문제점을 해결하기 위하여 PVC 수지 대신 폴리에틸렌 테레프탈레이트(PET) 수지 또는 폴리프로필렌(PP) 수지, 폴리에틸렌(PE)수지 및 ABS 수지 등을 기본 수지로 하여 목분을 혼합함으로써 친환경적이고 경제적인 문틀을 제공하려는 것이다.Accordingly, an object of the present invention is to mix wood powder with polyethylene terephthalate (PET) resin or polypropylene (PP) resin, polyethylene (PE) resin and ABS resin as a base resin instead of PVC resin to solve the problems of the prior art. By providing an eco-friendly and economical door frame.
또한, 본 발명은 여러 단계의 복잡한 공정 대신 간단한 공정으로 합성목재 문틀을 제조하려는 것을 목적으로 한다. In addition, an object of the present invention is to manufacture a synthetic wood door frame in a simple process instead of a complex process of several steps.
상기 목적을 달성하기 위하여, 본 발명자는 PVC 수지 대신 PET 또는 PP, PE, ABS 수지와 목분을 혼합한 합성목재수지를 기본 수지로 하여 문틀을 제조하였다.In order to achieve the above object, the present inventors manufactured a door frame using a synthetic wood resin mixed with PET or PP, PE, ABS resin and wood flour instead of PVC resin as a basic resin.
또한, 본 발명자는 PVC 수지를 먼저 압출 또는 사출하여 일정 형상의 금형으로 성형한 후 목재를 요철형으로 깎아 요철형으로 제작된 수지에 끼워 맞춘 후 외면에 시트를 부착시키는 번거로운 공정 대신 핫 프레스 방식으로 간단하고 경제적으로 문틀을 제조하는 방법을 발명하였다.In addition, the present inventors extrude or inject the PVC resin first into a mold of a predetermined shape, and then cut the wood into an uneven shape to fit the resin produced in the uneven form, and then instead of the cumbersome process of attaching the sheet to the outer surface by a hot press method Invented a method for manufacturing a door frame simply and economically.
도면을 참조하여 종래 기술과 본 발명을 상세히 설명한다.The prior art and the present invention will be described in detail with reference to the drawings.
도 2는 종래 문틀 제조방법을 도시한 것이다. 일정 모형에 PVC 등의 수지재(40)를 가하여 모양을 형성시킨다. 형성된 요철 모양에 대응되는 요철모양의 보강목재(30)를 적절한 위치에 접착시킨다. 접착 후 수지재 표면에 무늬 시트지(10)를 부착시킨다.Figure 2 illustrates a conventional door frame manufacturing method. The shape is formed by adding a resin material 40 such as PVC to a predetermined model. The concave-convex reinforcement wood 30 corresponding to the formed concave-convex shape is bonded to an appropriate position. After adhesion, the patterned sheet paper 10 is attached to the surface of the resin material.
종래 방법에 의하여 제조된 문틀의 경우 수지재 부분과 보강목재 부분은 열에 의한 수축, 팽창률이 달라 온도가 아주 낮거나 아주 높아지는 경우 문틀의 뒤틀림 현상이 발생할 수 있으며, 요철이 정확히 결합되지 않는 문제점이 있다.In case of the door frame manufactured by the conventional method, the resin part and the reinforcement wood part have different shrinkage and expansion rate due to heat, so when the temperature is very low or very high, the door frame may be distorted, and irregularities are not correctly combined. .
도 1은 본 발명의 방법으로 제조된 합성목재 문틀의 일부를 도시한 것이다. 합성목재 수지를 일정한 형태로 만들기 위하여 제조한 모형에 먼저 무늬 시트지(10)를 위치시키고, 진공 분위기로 시트지가 모형 내측에 밀착되도록 한다. 그 다음 문틀 형상에서 보강목재가 자리할 일정 위치에 보강목재(30)를 먼저 고정시킨다. 그 다음, 목분과 PET 또는 PP, PE, ABS 수지와의 혼합수지 펠렛을 분쇄한 것에 접착제를 가하여 모형 내부로 부어 넣고(20), 핫 프레스로 일정 압력을 가하여 문틀을 형성시킨다.Figure 1 shows a part of a synthetic wood door frame produced by the method of the present invention. The patterned sheet paper 10 is first placed on the manufactured model to make the synthetic wood resin into a uniform shape, and the sheet paper is adhered to the inside of the model in a vacuum atmosphere. Next, the reinforcement timber 30 is first fixed at a predetermined position where the reinforcement timber is to be positioned in the door frame shape. Then, the mixed powder pellets of the wood powder and PET or PP, PE, ABS resin is crushed and poured into the model by adding an adhesive (20), and a predetermined pressure is applied by a hot press to form a door frame.
본 발명의 방법으로 제조된 문틀은 보강목재와 합성목재수지 사이의 간극이 없고, 합성목재수지가 보강목재에 일정 정도 함침되어 문틀의 강도를 높여주며, 온도가 낮아지거나 높아지더라도 문틀이 뒤틀리는 문제가 없다. 또한, 간단한 1회의 핫 프레스 방식으로 문틀을 제조하게 되므로 경제적이다.The door frame manufactured by the method of the present invention does not have a gap between the reinforcement wood and the synthetic wood resin, synthetic wood resin is impregnated in the reinforcement wood to a certain extent to increase the strength of the door frame, the problem that the door frame is warped even if the temperature is lowered or higher none. In addition, it is economical to manufacture the door frame by a simple one-time hot press method.
아래에서 본 발명의 구성을 구체적인 실시예를 통하여 상세히 설명한다. 그러나, 본 발명의 범위가 아래의 실시예의 기재에 한정되는 것은 아니다.Hereinafter, the configuration of the present invention will be described in detail through specific examples. However, the scope of the present invention is not limited to the description of the following examples.
실시예Example
목분이 함유된 PET 수지를 이용하여 문틀을 가공함에 있어 먼저 합성수지와 목분이 혼합된 수지 조성물을 제조한다.In processing a door frame using a PET resin containing wood flour, a resin composition in which synthetic resin and wood flour are first prepared.
먼저 목분을 미세하게 분쇄하되, 바람직하게는 40∼200메쉬 정도로 만든 상태에서 최대한 건조하여 수분 함수율이 5% 미만인 상태로 만든다. 이와 같이 건조된 목분에 PET 수지와 접착제로서 폴리에테르 폴리올을 혼합하고, 통상 합성목재의 제조시 물성의 향상을 위하여 첨가되는 각종 첨가제를 넣고 20분가량 배합하여 압출기에 투입하여 펠렛을 제조한다. 압출 작업온도는 180∼250℃로 하며, 냉각 방법은 공냉식으로 한다.First, finely pulverize the wood powder, preferably in the state made about 40 to 200 mesh as dry as possible to make the water moisture content less than 5%. The polyether polyol is mixed with the dried wood powder as a PET resin and an adhesive, and various additives which are added to improve physical properties in the manufacture of synthetic wood are added and mixed for about 20 minutes to prepare pellets. Extrusion work temperature shall be 180-250 degreeC, and a cooling method shall be air cooling.
냉각된 펠렛을 그대로 용융하여 압출하는 경우 입자가 균일하지 않고 성형성이 저하되는 문제가 발생하였다. 그래서 본 발명자는 목분이 함유된 PET 수지 펠렛을 압출 또는 사출시 입자크기 60메쉬 이상으로 다시 분쇄하여 압출 또는 사출하는 경우 성형성 문제가 개선됨을 확인하였다. 통상 목분이 함유된 PET 수지 펠렛은 고속분쇄기(3,600rpm 이상)로 분쇄한다.When the cooled pellets are melted and extruded as they are, particles are not uniform and moldability is deteriorated. Thus, the present inventors confirmed that the molding problem is improved when the PET resin pellets containing wood powder are extruded or injected by pulverizing again to a particle size of 60 mesh or more. Usually, the PET resin pellets containing wood powder are pulverized by a high speed grinder (3,600 rpm or more).
분쇄된 조성물에는 접착제로서 폴리올을 첨가하여 일정 시간(약 5∼10분) 교반을 거쳐 프레스 작업을 실시한다. 일정한 형태의 목형에 실리콘, 에폭시 등으로 모형작업을 실시하여 핫 프레스 작업을 위한 모형을 생산한다.The pulverized composition is subjected to a press operation after adding a polyol as an adhesive and stirring for a predetermined time (about 5 to 10 minutes). Models are made of silicone, epoxy, etc. on a certain type of die to produce models for hot press work.
만들어진 모형 내측면에 무늬목 등의 시트지, 통상 PVC 재질의 시트지를 굴곡에 맞게 위치시키고, 약 40∼60℃ 정도의 열을 가한 상태에서 진공 분위기를 형성하여 모형과 시트지가 밀착된 상태에서 보강용 합판 또는 목재를 규격에 맞게 절단한다.Reinforcement plywood is placed on the inner side of the model, which is made of sheet paper, such as veneer, or PVC sheet, which is usually made of PVC, according to the curvature, and a vacuum atmosphere is formed under heat of about 40 to 60 ° C. Or cut the wood to specification.
절단된 보강용 합판 또는 목재를 모형의 일정 부분에 위치시키고, 수지와 용제, 접착제 등이 혼합된 조성물을 부어 20∼100톤의 압력을 가한다. 프레스 성형시간은 15∼25분 정도로 하고, 성형을 할 때는 상하 고정판에 열을 가하여 성형시간을 단축하고, 제품 강도를 조절할 수 있다.The cut reinforcement plywood or wood is placed in a portion of the model, and a composition mixed with a resin, a solvent, and an adhesive is poured and a pressure of 20 to 100 tons is applied. The press molding time is about 15 to 25 minutes, and when forming, heat is applied to the upper and lower fixing plates to shorten the molding time and adjust the product strength.
성형이 끝난 제품은 냉각하여 변형을 방지하며, 냉각시간은 약 20분 정도로 상온에서 실시한다.The finished product is cooled to prevent deformation and the cooling time is about 20 minutes at room temperature.
본 발명의 문틀은 시트지가 깔린 모형 위에 일정 위치에 보강 목재를 위치시키고 배합된 조성물을 부어 열을 가하여 성형하기 때문에 수지 조성물이 보강 목재에 함침되어 문틀의 강도가 높아진다. Since the door frame of the present invention is formed by placing a reinforcement wood at a predetermined position on a sheet-covered model and pouring the compounded composition by applying heat, the resin composition is impregnated into the reinforcement wood, thereby increasing the strength of the door frame.
또한, 본 발명의 문틀은 목분을 함유한 합성목재수지를 기본수지로 하므로 환경친화적이고, 유해가스를 발생시키지 않는다.In addition, the door frame of the present invention is environmentally friendly and does not generate harmful gases because the synthetic wood resin containing wood powder as a base resin.
또한, 본 발명의 문틀은 수지 따로, 보강목 따로 요철 모양을 형성하여 접착시키는 방식이 아니므로 수지와 보강목재 사이의 간격이 없어 견고하고 뒤틀림 없는 문틀을 제공할 수 있다.In addition, since the door frame of the present invention is not a method of forming a concave-convex shape separately from the resin and the reinforcement wood separately, there is no gap between the resin and the reinforcement wood, thereby providing a firm and warped door frame.
뿐만 아니라, 본 발명은 문틀 제조공정 중 보강 목재에 수지가 일정 정도 함침되고, 기본수지에 목분을 함유하므로 여름, 겨울과 같이 온도차가 심할 때 발생하는 문틀 수축 현상이 발생하지 않는다.In addition, the present invention because the resin is impregnated to a certain degree in the reinforcement wood during the door frame manufacturing process, and contains the wood powder in the base resin does not occur the door frame shrinkage phenomenon occurs when the temperature difference is severe, such as summer and winter.
나아가, 본 발명은 간단한 공정으로 저렴한 가격의 문틀을 제공할 수 있다.Furthermore, the present invention can provide a low cost door frame in a simple process.
도 1은 본 발명의 방법에 의하여 제조된 합성목재 문틀 일부를 도시한 것이다.Figure 1 shows a part of a synthetic wood door frame produced by the method of the present invention.
도 2는 종래 문틀 제조방법을 도식화한 것이다.2 is a diagram illustrating a conventional door frame manufacturing method.
