본 발명은 아무곳에서 쉽게 얻을 수 있는 나무 폐기물을 활용하고, 또한 이에 열경화성 접착제와 일정길이 이하로 절단된 섬유사를 일정비율로 혼합시킨 다음 그 내부로 부강부재를 배열한 상태로 고압프레스에서 가열, 가압하는 열성형 제조방법으로 보를 제조하므로서, 건축 및 건설현장에서의 수요에 대한 공급부족을 해결하고, 생산자는 물론 그 이용자로 하여금 경제적인 이익을 줄 수 있도록 하는 것이다.The present invention utilizes wood waste that can be easily obtained anywhere, and also mixed with a thermosetting adhesive and a fiber yarn cut to a certain length to a certain ratio and then heated in a high-pressure press in a state in which the steel member is arranged therein. By manufacturing the beam by pressurizing thermoforming manufacturing method, it solves the shortage of supply and demand in the construction and construction site, and provides economic benefits to producers and their users.
본 발명의 목적은 강도가 우수한 목재와 합성수지재의 합성보를 제공하는데 있다.An object of the present invention is to provide a composite beam of wood and synthetic resin material having excellent strength.
본 발명의 다른 목적은 부식의 염려가 없어 그 수명을 크게 연장시킬 수 있도록 된 합성보를 제공하는데 있다.Another object of the present invention is to provide a composite beam that can be greatly extended its life without fear of corrosion.
본 발명은 목재 폐기물에서 손쉽게 얻을 수 있는 파쇄된 목재의 칩(Chip)을 주성분으로 하고, 이에 율섬유사, 화학섬유사, 자연섬유사, 강(steel)섬유등의 절단물과, 철근 및 철사로 이루어지는 보강부재를 단면 내부로 배열토록 한 상태에서 무공해성 열가소성수지와 촉진제를 혼합하여 이를 130∼150℃의 온도를 유지시키면서 30∼80㎏/㎠의 압력을 가진 고압성형프레스에서 일정시간동안 가압하는 것에 의해 달성된다.The present invention is based on the chip (chip) of crushed wood that can be easily obtained from wood waste, and thus cuts such as velvet fiber, chemical fiber, natural fiber, steel fiber, steel and wire The non-toxic thermoplastic resin and the accelerator are mixed in a state where the reinforcing member is arranged inside the cross section and pressurized for a predetermined time in a high pressure molding press having a pressure of 30 to 80 kg / ㎠ while maintaining the temperature of 130 to 150 ° C. Is achieved.
이하에서 본 발명을 제조공정에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by the manufacturing process as follows.
[제1공정 : 원료의 혼합공정][Step 1: Mixing Process of Raw Materials]
5∼30mm 정도로 파쇄된 목재칩 70-90부70-90 parts of shredded wood chips about 5 ~ 30mm
열경화성 수지 10-30부Thermosetting resin 10-30 parts
섬유단사물 10-20부10-20 parts of fiber
유기과산화물 0.2-2부(이상중량비임)0.2-2 parts of organic peroxide (ideal weight ratio)
상기 비율로 혼합된 혼합물을 혼합기에서 골고루 혼합시킨다.The mixture mixed at the above ratios is mixed evenly in a mixer.
상기 유기 과산화물은 과산화 벤졸, 과산화 라우릴 t-부틸페옥시네오데카노이에트, t-부틸퍼옥시-2-에틸헥사노에이트를 포함한 것이다.The organic peroxide includes benzol peroxide, lauryl peroxide t-butylphenoxy neodecanoate, t-butylperoxy-2-ethylhexanoate.
그리고 상기에서 열경화성수지는 무해한 폴리에스텔수지 또는 비닐수지 및 폴리우레탄재중에 선택하여 사용하고, 섬유단사물은 유리섬유사, 화학섬유사, 자연섬유사 또는 강(steel) 섬유를 일정길이 이하로 절단된 것을 단독, 또는 복합하여 사용한다.And the above-mentioned thermosetting resin is selected from the harmless polyester resin or vinyl resin and polyurethane material, and the fiber single yarn is cut to glass fiber yarn, chemical fiber yarn, natural fiber yarn or steel fiber to a certain length or less It is used alone or in combination.
[제2공정 : 제조공정][Step 2: Manufacturing Process]
일정형태의 몰드내에 제1공정에서의 혼합물을 공급한 후 몰드내에서 상기 혼합물의 내부로 위치토록 보강부재를 배열하고, 30~80㎏/㎠의 압력과 130℃~150℃ 온도가 유지되는 고압성형프레스에서 10분정도 가압한 후, 몰드에서 성형물을 인출하고 자연건조시키면 본 발명의 제조공정은 완료된다.After supplying the mixture in the first step into the mold of a certain type, the reinforcing member is arranged to position the mixture into the inside of the mold, and the high pressure is maintained at a pressure of 30 ~ 80kg / ㎠ and 130 ℃ ~ 150 ℃ temperature After pressurizing for about 10 minutes in the molding press, the molded product is taken out of the mold and dried naturally, and the manufacturing process of the present invention is completed.
이때, 제2공정에서 몰드는 완성하고자 하는 각 용도별 보의 형상과 길이에 따라 다른 형태의 몰드를 사용하면, 성형물은 예로서 I 형빔, H 형빔 , L 형빔과 같은 형강과, 원형 및 사각형상과 같은 다양한 형상의 보를 제작할 수가 있는 것이다.In this case, in the second step, if the mold uses a mold of a different shape according to the shape and length of the beam for each application to be completed, the molding may be formed of, for example, a section steel such as an I-beam, an H-beam, an L-beam, The same variety of beams can be produced.
상기 보강부재는 금속재로써 강도보강을 위해 합성물의 내부로 위치되는 것으로, 그 외부로 합성물이 감싸지므로 부식의 염려가 없다.The reinforcing member is a metal material, which is positioned inside the composite for strength reinforcement, and the composite is wrapped outside thereof, so there is no fear of corrosion.
그리고, 상기 보강부재의 형상은 위에서 예로 명시한 I형 보를 완성할 경우 I형의 보강부재를 선택하여 그 외부로 합성물이 감싸지도록 성형토록 하거나, 또는 비교적 강도가 우수한 철근 및 철사 구조물을 일정간격으로 길이 방향을 따라 다수 배열하는 것에 의해 동일한 강도보강 효과를 가질 수 있도록 하여도 무방하다.In addition, the shape of the reinforcing member is selected to form a reinforcing member of the I-type when completing the I-shaped beam specified in the example above, or to be molded so that the composite is wrapped around it, or the length of the reinforcing steel and wire structure having a relatively high strength at regular intervals It may be possible to have the same strength reinforcing effect by arranging a large number along the direction.
상술한 공정으로 이루어지는 본 발명은 용도에 따라 지주 및 보를 대체하여 이용할 수 있도록 하는 것이다.The present invention made of the above-described process is to be used to replace the posts and beams depending on the application.
따라서, 지지 강도를 보다 강화시킬 수 있을 뿐만 아니라, 표면 부식의 염려가 전혀 없어 장시간 경과로 인한 강도저하의 염려가 없으며, 표면부식이 이루어지지 않으므로 그 사용수명을 크게 연장시켜 이용자로 하여금 경제적인 이익을 줄 수 있는 등의 매우 유용한 발명인 것이다.Therefore, not only can the support strength be further strengthened, there is no fear of surface corrosion, and there is no fear of strength degradation due to prolonged passage, and since surface corrosion does not occur, the service life is greatly extended by the user. It is very useful invention such as can give.
