Description
본 발명은 제조방법에 관한 것으로, 보다 상세하게는 폴리프로필렌(PP)의 원단이 첨가되는 휄트과정을 생략하고 폐화학섬유 및 천연섬유와 수지를 혼합하여 일련의 단계를 거쳐 제조되는 섬유판재 및 그의 제조방법에 관한 것이다.The present invention relates to a manufacturing method, and more particularly, a fiber board material manufactured through a series of steps by omitting the process of adding the fabric of polypropylene (PP) and mixing waste chemical fiber, natural fiber and resin and its It relates to a manufacturing method.
현재 섬유제품 제조공장에서 생산중에 발생되는 폐섬유와 천조각 또는 이미 사용된 후 폐기되는 폐섬유류의 양이 상당한 수준을 넘어서고 있으므로, 이러한 폐섬유류를 폐기처분하는 방법에 있어서 심각한 문제로 대두되고 있다.At present, the amount of waste fibers and pieces of fabric generated during production in textile manufacturing plants or waste fibers discarded after being used is exceeding a considerable level, which is a serious problem in the method of disposing of such waste fibers.
즉, 폐섬유를 매립한 때에는 수십년간 썩지 않으므로 땅 속의 산소공급을 차단하여 토양의 황폐화가 발생되며, 소각의 경우에는 유황, 미지트, 다이옥신 등의 유해성 가스가 발생되어 대기오염을 심화시킴은 물론, 대기권의 오존층을 파괴함에 따라 햇빛에 의한 피부암의 원인이 되고 있다.In other words, when the waste fiber is embedded, it does not decay for decades, so the oxygen supply in the ground is blocked, causing the soil to be depleted, and in case of incineration, harmful gases such as sulfur, mijit, and dioxin are generated to intensify air pollution. As the ozone layer in the atmosphere is destroyed, it is a cause of skin cancer caused by sunlight.
따라서, 최근에는 일개국의 문제가 아닌 세계적으로 지구환경문제로 심각하게 대두되어 세계무역기구가 제창하는 공해산업의 수출금지조치와 함께 자원의 무기화로 산유국의 발언권이 강화되고 있으며, 판재의 원료로 사용되는 목재와 철 또한 한정된 국가에서 한정된 양을 갖고 있으므로 향후에는 고갈될 위기에 처하게 되어 대체 제품의 개발을 서둘러야 하는 중대한 시점에 와 있는 것이다.Therefore, in recent years, as a global environmental problem, not just one country, the oil industry's right to speak is strengthened by the weaponization of resources along with the ban on exports of the pollution industry promoted by the World Trade Organization. The timber and iron used are also in limited countries and are at a critical time to run out of alternatives, as they are in danger of being depleted in the future.
한편, 종래의 섬유폐기물을 이용한 섬유판재 제조방법에서는 폐화학섬유를 5㎝ 이하의 조각편으로 절단하여 타면기에 넣어 솜처럼 타면한 다음 롤타입(Roll type)으로 감아서 된 소재의 타면설(이하 '휄트'라 칭함)에 결합제인 열경화성 수지를 30g/㎡의 양으로 균일하게 양면도포한 후, 휄트의 함수량이 13%이하가 되도록 건조한 다음 휄트를 용도별로 정해진 제품의 치수로 재단하여 사용온도 210℃의 열압프레스에 넣고 제품의 불량을 줄이기 위해서 에어를 방출한 후 제품의 단위압력이 70㎏/㎠이 되도록 약 5 ~ 10분간 압축·성형시키고, 가압성형이 완료된 제품은 다시 냉각프레스에서 급속냉각하여 제품을 완성하도록 하였다(공고특허특0161818호).On the other hand, in the conventional method of manufacturing a fiber board material using fiber waste, waste chemical fiber is cut into pieces of 5 cm or less, put into a cotton noodle machine, and then spun like cotton, and then rolled into a roll type (roll type) (hereinafter ' After coating both sides of the thermosetting resin as a binder in an amount of 30 g / m2 uniformly, dry it so that the moisture content of the bolt is 13% or less, and cut the bolt to the size of the product determined for each application. In order to reduce product defects, the product is compressed and molded for about 5 to 10 minutes so that the unit pressure of the product becomes 70㎏ / ㎠, and the product after press molding is rapidly cooled by cooling press again. The product was to be completed (Publication Patent No. 0161818).
그러나 상기와 같은 종래기술에서는 다음과 같은 문제점이 있다.However, the prior art as described above has the following problems.
즉, 종래기술에서 사용되는 휄트는 폴리프로필렌(Poly Propylene : PP)원단을 첨가시켜 폐화학섬유와 함께 롤(Roll)로 감아서 제조하게 되는데, 상기 휄트의 제조비용이 전체 섬유판재 제조비의 60% 이상 차지하게 됨으로써 섬유판재의 제조단가가 상승하는 문제점이 있다.In other words, the felt used in the prior art is produced by adding a polypropylene (PP) fabric to the roll with the waste chemical fibers in a roll (Roll), the cost of manufacturing the felt 60% of the total fiber board manufacturing cost By occupying the above, there exists a problem that the manufacturing cost of a fiber board material rises.
그리고, 상기 폴리프로필렌(PP)의 첨가로 섬유판재의 가공시에 유해물질이 더 배출되는 문제점이 있다.In addition, there is a problem that harmful substances are further discharged during the processing of the fiberboard material by the addition of the polypropylene (PP).
또한, 상기 휄트가 폴리프로필렌(PP)의 결대로 폐화학섬유와 박리되는 문제점도 있다.In addition, there is a problem that the felt is peeled off from the waste chemical fibers as a polypropylene (PP).
따라서 상기와 같은 문제점을 해결하기 위한 본 발명의 목적은, 폴리프로필렌(PP)의 원단이 첨가되는 휄트과정을 생략하고 폐화학섬유와 수지를 혼합하여 일련의 단계를 거쳐 제조되는 섬유판재 및 그의 제조방법을 제공하는 것이다.Therefore, an object of the present invention for solving the above problems is to omit the chopped process in which the fabric of polypropylene (PP) is added, the fiber board material is manufactured through a series of steps by mixing waste chemical fibers and resin and its manufacture To provide a way.

상기 혼합단계에서의 수지는 멜라민수지와 요소수지이며, 그 혼합비율은 상기 폐화학섬유 95%와 상기 멜라민수지 및 요소수지가 5%인 것을 특징으로 한다.The resin in the mixing step is melamine resin and urea resin, the mixing ratio is characterized in that the waste chemical fiber 95% and the melamine resin and urea resin is 5%.
상기 건조단계는 마이크로웨이브로 약 2분 ~ 3분동안 건조하여 수분함유량이 5%±3%로 유지하는 것을 특징으로 한다.The drying step is a microwave for about 2 minutes to 3 minutes to dry characterized in that the moisture content is maintained at 5% ± 3%.

이와 같은 구성을 가지는 본 발명에 의하면, 섬유판재의 제조단가가 월등히 절감되며 작업시간이 단축되는 이점이 있다.According to the present invention having such a configuration, there is an advantage that the manufacturing cost of the fiber board material is significantly reduced and the working time is shortened.
이하에서는 상기한 바와 같은 본 발명에 의한 섬유판재 및 그의 제조방법의 바람직한 실시예를 첨부된 도면을 참고하여 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the fiber board according to the present invention as described above and a manufacturing method thereof will be described in detail.
도 1 에는 본 발명의 바람직한 실시예에 따른 섬유판재 제조방법의 개략적인 공정흐름도가 도시되어 있다. 이에 도시된 바와 같이 본 발명에 의한 섬유판재 및 그의 제조방법은, 폐화학섬유 및 천연섬유와 수지를 혼합하는 혼합단계(S10)에서부터 시작된다.Figure 1 shows a schematic process flow diagram of a method for manufacturing a fiber board according to a preferred embodiment of the present invention. As shown therein, the fiber board material and the method of manufacturing the same according to the present invention start from the mixing step (S10) of mixing waste chemical fiber, natural fiber and resin.
상기 혼합단계(S10)는 천연섬유와 섬유제품 제조회사나 의류 제조업체에서 생산과정 중에 발생되는 폐화학섬유를 수거하여 솜처럼 타면한 다음, 수지 즉 멜라민수지(Melamin Resin) 및 요소수지(Urea Resin)와 혼합하게 된다. 상기 혼합단계(S10)에서의 혼합비율은 천연섬유 및 폐화학섬유 95%와 멜라민수지와 요소수지 5%, 그리고 물 7.5%의 비율로 혼합하게 된다.The mixing step (S10) is to collect the waste chemical fibers generated during the production process in the natural fiber and textile product manufacturers or clothing manufacturers, such as cotton, then resin, that is, melamine resin (Melamin Resin) and urea resin (Urea Resin) Mixed with. The mixing ratio in the mixing step (S10) is mixed with 95% natural fiber and waste chemical fiber, melamine resin and urea resin 5%, and water 7.5%.
상기와 같이 멜라민수지와 요소수지를 섞어서 함께 사용하는 이유는, 상기 멜라민수지의 값이 요소수지의 값보다 다소 비싸기 때문에 가능한 한 멜라민수지를 적게 사용하여 최종 생산물인 섬유판재의 제조단가를 낮추기 위함이다.The reason why the melamine resin is mixed with the urea resin as described above is to lower the manufacturing cost of the final product fiber board material by using as little melamine resin as possible because the melamine resin is more expensive than the urea resin. .
그리고, 상기 멜라민수지 및 요소수지는 아래에서 설명할 열간성형단계(S30)에서 에어(Air)를 방출시키기 위한 시간을 절약하기 위하여 휘발성 성분이 3% 이내로 한정하여야 한다. In addition, the melamine resin and urea resin should be limited to less than 3% volatile components in order to save time for releasing air in the hot forming step (S30) to be described below.
상기 혼합단계(S10)를 거친 다음에는 혼합단계(S10)에서 생산되는 혼합물을 건조시키는 건조단계(S20)가 실시된다. 상기 건조단계(S20)는 마이크로웨이브(Micro wave)로 약 2분 ~ 3분동안 건조하여 상기 혼합단계(S10)에서 첨가된 물의 함유량을 5%±3%로 유지하게 한다.After the mixing step (S10) is followed by a drying step (S20) for drying the mixture produced in the mixing step (S10). The drying step (S20) is dried in a microwave (Micro wave) for about 2 minutes to 3 minutes to maintain the content of water added in the mixing step (S10) to 5% ± 3%.
이렇게 수분의 함유량을 5%±3%의 범위로 유지하는 이유는, 상기 수지의 휘발성 성분 함량에서와 같이 열간성형단계(S30)에서의 작업시간을 단축하기 위한 것이다. 즉, 상기 휘발성 함량이나 수분함유량이 많아지게 되면 열간성형단계(S30)에서 에어(Air)를 방출시키기 위한 시간이 많이 소요되므로, 이러한 에어방출시간을 절약하기 위하여 상기와 같은 범위의 휘발성 함량과 수분함유량으로 유지하게 된다.The reason for maintaining the moisture content in the range of 5% ± 3% is to shorten the working time in the hot forming step (S30) as in the volatile component content of the resin. That is, when the volatile content or water content increases, it takes a lot of time to release the air in the hot forming step (S30), in order to save the air discharge time, the volatile content and moisture in the above range It is kept at content.
상기 건조단계(S20)를 거친 다음에는 상기 혼합물을 고온프레스에서 판재로 성형하는 열간성형단계(S30)를 실시하게 된다. 이러한 열간성형단계(S30)는 온도가 180℃±5℃, 단위압력이 40㎏/㎠의 조건으로 약 3분동안 실시하게 된다. After the drying step (S20) it is carried out a hot forming step (S30) for molding the mixture into a plate at a high temperature press. This hot forming step (S30) is carried out for about 3 minutes under conditions of the temperature of 180 ℃ ± 5 ℃, the unit pressure of 40 kg / ㎠.
여기에서 온도범위와 압력조건, 그리고 소요되는 시간이 종래의 섬유판재 제조방법에서보다 낮고 적은 이유는, 종래의 폴리프로필렌(Poly Propylene : PP)원단을 첨가시켜 폐화학섬유와 함께 롤(Roll)로 감아서 제조하게 되는 휄트를 사용하지 않기 때문이며, 또 하나는 상기 건조단계(S20)에서 수지 성분을 제외한 수분을 완전건조에 가깝도록 건조할 수 있기 때문이다.Here, the temperature range, pressure conditions, and the time required are lower and less than those of the conventional fiber board manufacturing method. The conventional polypropylene (PP) fabric is added to the roll together with the waste chemical fiber. This is because it does not use the chopped to be manufactured by winding, and another is because the drying step (S20) can be dried to close to complete drying, except for the resin component.
상기 열간성형단계(S30)를 거친 다음에는 상기 판재를 냉각프레스에서 급속냉각시키는 냉각단계(S40)가 실시되는데, 상기 냉각단계(S40)는 상기 고온프레스의 10% ~ 20% 압력으로 약 3분동안 냉각시키게 된다. After the hot forming step (S30), the cooling step (S40) for rapid cooling of the plate in a cooling press is carried out, the cooling step (S40) is about 3 minutes at 10% ~ 20% pressure of the high temperature press Will be cooled.
그런 다음에는 상기 냉각단계(S40)를 거친 판재를 정해진 규격대로 절단하는 재단단계(S50)를 실시하게 된다. 이렇게 하면 폐화학섬유를 이용한 섬유판재가 제작되는 것이다.Then, the cutting step (S50) to cut the plate passed through the cooling step (S40) to a predetermined standard. This will produce a fiberboard using waste chemical fibers.
이러한 본 발명의 범위는 상기에서 예시한 실시예에 한정하지 않고, 상기와 같은 기술범위 안에서 당업계의 통상의 기술자에게 있어서는 본 발명을 기초로 하는 많은 다른 변형이 가능할 것이다.The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
예를 들어, 상기와 같은 방법에 일정량의 안료 또는 착색제를 첨가하거나 여러가지 무늬를 삽입하여 다양한 종류의 섬유판재를 제작할 수 있음은 물론이다.For example, it is a matter of course that various kinds of fiberboard materials can be manufactured by adding a certain amount of pigment or colorant to the above method or inserting various patterns.
위에서 상세히 설명한 바와 같이 본 발명에 의한 섬유판재 및 그의 제조방법에서는, 폴리프로필렌(PP)의 원단이 첨가되는 휄트과정을 생략하고 폐화학섬유 및 천연섬유를 수지와 혼합하여 일련의 단계를 거쳐 제조되도록 구성하였다.As described in detail above, in the fiber board material and the method of manufacturing the same, the chopped process of adding the fabric of polypropylene (PP) is omitted, and the waste chemical fiber and natural fiber are mixed with the resin to be manufactured through a series of steps. Configured.
따라서, 종래 휄트의 제조과정을 생략함으로써 섬유판재 제조단가가 월등히 절감될 뿐만 아니라 섬유판재를 제조하는 작업시간이 상당히 단축되는 효과가 기대된다.Therefore, the omission of the manufacturing process of the conventional bolt is expected to significantly reduce the manufacturing cost of the fiber board material as well as significantly shortening the work time for manufacturing the fiber board material.
그리고, 종래의 휄트 제조과정에서 사용하던 폴리프로필렌(PP)을 제거함으로써 섬유판재의 가공시에 발생되는 유해물질의 배출을 방지할 수 있는 효과가 기대된다.In addition, by removing the polypropylene (PP) used in the prior art manufacturing process, it is expected that the effect of preventing the emission of harmful substances generated during the processing of the fiberboard material.
도 1 은 본 발명의 섬유판재 및 그의 제조방법의 바람직한 실시예에 따른 개략적인 공정흐름도.1 is a schematic process flow diagram according to a preferred embodiment of the fiberboard of the present invention and a manufacturing method thereof.
