본 발명에 적용된 목분을 이용한 인조목의 제조방법은 도 1 에 도시된 바와 같이 실시하게 되는 것이다.Method for producing artificial wood using wood powder applied to the present invention is to be carried out as shown in FIG.
본 발명에 적용된 인조목은 문틀, 창틀, 마루재, 내·외벽마감재, 각 목재, 인테리어자재 등 건축용으로 다양하게 사용할 수 있는 것으로, 이때 인조목에 구성되는 성분제와 비율은 아래 표에서와 같다.Artificial wood applied to the present invention can be used in various ways for construction, such as door frames, window frames, flooring materials, interior and exterior wall finishing materials, each wood, interior materials, the components and ratios of the artificial wood is shown in the table below.
-- 아 래 ---Below-
실시예Example
상기와 같이 구성되는 목분의 비율은 중량비로서 약 20∼50%가 적당한 것으로, 이때 목분의 비율이 중량비로서 20% 이하일 경우에는 성형성은 좋으나 물성이 낮은 문제점이 있고, 중량비로서 50% 이상일 경우에는 물성은 좋으나 성형성이 저하되는 문제점이 있기 때문에 목분의 비율은 중량비로서 20∼50%가 적당한 것이다.The ratio of wood flour constituted as above is about 20 to 50% by weight, and in this case, when the ratio of wood flour is less than 20% by weight, the moldability is good but the physical properties are low. Is good, but there is a problem that the moldability is lowered, so the ratio of wood powder is suitably 20 to 50% by weight.
상기 본 발명에 적용되는 목분의 종류는 활엽수, 침엽수 등의 다양한 목제가 사용됨은 물론 각종 잡목, 폐목, 톱밥 등도 사용되어 재활용 할 수 있도록 한 것으로, 이때 목분은 100∼200 매쉬의 미세한 입자로 분쇄되어 사용되는 것이고, 상기 목분의 종류나 입자의 크기에 따라 다양한 질감의 인조목을 성형할 수 있음은 물론이다.The type of wood powder to be applied to the present invention is used to recycle various wood, waste wood, sawdust, etc., as well as various wood such as hardwood, conifer, etc. At this time, the wood powder is crushed into fine particles of 100 to 200 mesh It is to be used, it is a matter of course that the artificial wood of various textures can be molded according to the type of wood flour or the size of the particles.
또한 상기 커플링제는 무기물인 목분의 입자와 유기물인 합성수지를 상호 접착시키는 것으로, 중량비로서 0.5∼1%가 적당한 것이다. 이때 커플링제의 비율이 중량비로서 0.5%이하일 경우에는 코팅력이 저하되어 목분의 탄화가 발생되는 문제점이 있고, 커플링제의 비율이 중량비로서 1% 이상일 경우에는 코팅력은 좋으나 합성수지 점착력 증가에 따른 금형부와의 마찰력 증가 및 커플링제가 고가이기 때문에 비용이 상승되는 문제점이 발생되었다.In addition, the coupling agent is to bond the particles of wood powder, which is an inorganic material, and the synthetic resin, which is an organic material, to 0.5 to 1% by weight. In this case, when the ratio of the coupling agent is 0.5% or less as the weight ratio, the coating power is deteriorated and carbonization of wood powder is generated. When the ratio of the coupling agent is 1% or more as the weight ratio, the coating power is good, but the mold due to the increase in the adhesive strength of the resin Increasing the frictional force with the wealth and the coupling agent is expensive, a problem arises that the cost increases.
상기와 같이 구성된 인조목의 성분중 목분은 전처리 과정을 거치는 것이다. 즉, 100∼200매쉬의 미세한 입자로 분쇄된 목분을 통상의 건조장치(Hopper Dryer)에 투입한 후 건조하는 것으로, 이때 목분에 함유된 7% 정도의 수분은 2%이하로 떨어지게 된다.Among the components of the artificial tree configured as described above is the wood powder is subjected to a pretreatment process. In other words, the wood powder pulverized into fine particles of 100 to 200 mesh is put into a dry dryer (Hopper Dryer), and then dried. At this time, about 7% of the moisture contained in the wood powder falls below 2%.
본 발명은 이후 상기 인조목의 성분을 1∼3차로 배합하는 공정을 거치는 것이다.The present invention is then subjected to the step of blending the components of the artificial wood first to third.
즉, 1차 배합은 상기 내열안정제, 발포제(190∼230℃에서 발포), 발포조제(150∼160℃에서 발포), 가공조제, 충진제, 백색안료를 통상의 히팅믹서(Heating Mixer)와 쿨링믹서(Cooling Mixer)를 통과시켜 배합하는 것으로, 이때 상기 히팅믹서의 공정조건은 약 115∼125℃가 적당한 것이다. 즉, 공정조건의 온도가 115℃이하일 경우에는 화학반응(배합율)이 저하되는 문제점이 있고, 공정조건의 온도가 125℃이상일 경우에는 탄화반응이 일어나기 때문에 상기 115∼125℃의 설정온도가 적당하다.That is, the primary compounding agent is a heat-mixing agent, a foaming agent (foaming at 190 ~ 230 ℃), a foaming aid (foaming at 150 ~ 160 ℃), processing aids, fillers, white pigments conventional heating mixer (Heating Mixer) and cooling mixer (Cooling Mixer) to pass through, and the mixing conditions of the heating mixer is about 115 ~ 125 ℃ is suitable. That is, when the temperature of the process conditions is 115 ℃ or less, there is a problem that the chemical reaction (combination rate) is lowered, and when the temperature of the process conditions is 125 ℃ or more, the carbonization reaction occurs, the set temperature of 115 to 125 ℃ is suitable. .
또한 2차 배합은 상기 건조시킨 목분과 커플링제를 히팅믹서(Heating Mixer)와 쿨링믹서(Cooling Mixer)를 통과시켜 건조 배합시키는 것으로, 공정조건은 130∼140℃의 반응온도가 적당한 것이다.In the second blending, the dried wood powder and the coupling agent are dry blended by passing through a heating mixer and a cooling mixer, and the process conditions are a reaction temperature of 130 to 140 ° C.
또한 3차 배합은 상기 1,2차 배합 원료를 쿨링교반(Cooling Blender)을 이용하여 혼합하는 것이다.In addition, the tertiary blending is to mix the first and second blending raw materials using a cooling blender.
상기와 같이 배합이 완료되면 이를 압출하는 공정을 거쳐 인조목을 성형하는 것이다.When the blending is completed as described above is to artificial wood molding through a process of extrusion.
즉, 상기 배합이 완료된 원료를 건조장치(10)인 호퍼드라이어(Hopper Dryer)에 넣어 건조시키는 것으로, 이때 수분을 1∼3%까지 제거할 수 있도록 한 것이다.That is, the blended raw material is put into a hopper dryer (Hopper Dryer) of the drying apparatus 10 to dry, at this time to remove the moisture by 1 to 3%.
상기와 같이 수분이 제거된 원료는 압출장치(20)를 통해 배출되는 것으로, 이 압출장치(10)의 후단에 형성된 금형을 통해 원료가 압출되어 배출되는 것이다.As described above, the raw material from which moisture is removed is discharged through the extrusion device 20, and the raw material is extruded and discharged through a mold formed at the rear end of the extrusion device 10.
이후 상기 압출장치(20)를 통해 배출된 원료는 냉각장치(30)를 통과하는 것으로, 상기 냉각장치(30)는 1차 2차 3차로 나뉘어져 구성된다. 그리고 상기 1,2차는 통과하는 원료를 진공상태에서 냉각하는 것이고, 3차는 통과하는 원료가 냉각되도록 한 것이다.Since the raw material discharged through the extrusion device 20 passes through the cooling device 30, the cooling device 30 is divided into primary secondary secondary. And the first and second are to cool the raw materials passing through in a vacuum state, and the third is to allow the raw materials to pass through to be cooled.
이어서 상기 냉각장치(30)를 통과한 원료는 인출장치(40)를 통해 배출되는 것이고, 상기 인출장치(30)를 통해 배출되는 원료는 코팅처리장치(50)를 통과하게 된다.Subsequently, the raw material having passed through the cooling device 30 is discharged through the withdrawal device 40, and the raw material discharged through the withdrawal device 30 passes through the coating processing device 50.
상기 코팅처리장치(50)는 상기 원료의 표면에 폴리우레탄(Polyurethane)의 표면강화제를 스프레이 하는 것으로, 특수용도의 제품은 표면경도상승을 위하여 표면강화제 코팅작업을 수행하는 것이다.The coating treatment apparatus 50 is to spray a surface hardener of polyurethane (Polyurethane) on the surface of the raw material, the product of a special purpose is to perform a surface hardener coating operation for the surface hardness increase.
상기와 같이 코팅처리장치(50)를 통과한 원료는 절단장치(60)를 통과하는 것으로, 작업자가 원하는 길이로 절단하여 각종 건축자제로 사용할 수 있도록 한 것이다.The raw material that has passed through the coating treatment device 50 as described above is to pass through the cutting device 60, so that the worker can be cut to a desired length to be used in various building materials.
