폐폴리에스테르, 산업자재용 시이트Waste Polyester, Sheet for Industrial Materials
Description
본 발명은 폐폴리에스테르섬유를 함유하는 산업자재용 시이트에 관한 것으로, 보다 상세히 말하면 주로 폐타이어에서 나오는 타이어 코오드 등 폴리에스테르계로 이루어진 설물을 네오프렌, 천연고무, 합성고무 또는 코르크와 혼합하여 신생제품과 동일하거나 그 이상의 물성을 갖도록 재생할 수 있는 산업자재용 시이트에 대한 것이다.The present invention relates to a sheet for industrial materials containing waste polyester fiber, more specifically, to a new product by mixing polyester-based water, such as tire cords, mainly from waste tires, with neoprene, natural rubber, synthetic rubber or cork. The present invention relates to a sheet for industrial materials that can be recycled to have the same or higher properties.
자원을 유효 적절히 활용함과 동시에 중요한 사회문제로 등장되어 있는 환경 오염도 방지하기 위하여 전세계적으로 고분자 물질을 재생화시키는 문제가 긴요한 과제로 대두되고 있다.In order to effectively utilize resources and to prevent environmental pollution, which has emerged as an important social problem, the problem of regenerating high molecular materials from all over the world has emerged as an important task.
타이어 제조시 고무보강재로 사용된 폴리에스테르섬유 등으로 이루어지는 타이어 코드는 타이어를 폐기할 때 별도의 쓸모가 없어 전혀 재활용되지 않고 단순히 폐기처분되어 자원의 낭비와 함께 환경오염을 야기시키는 주범이 되고 있다.Tire cords made of polyester fibers used as rubber reinforcements in tire manufacturing are not useful at the time of disposal of tires and are not recycled at all.
또, 생고무를 전량 수입에 의존하고 있는 우리나라로서는 고무의 재활용이 시급한 문제가 아닐 수 없다.In addition, the recycling of rubber is an urgent problem in Korea, where raw rubber is entirely dependent on imports.
현재 천연고무를 주제로 하는 대형 버스 및 트럭의 타이어는 분쇄된 후에 재생제를 혼합하여 약 200℃로 가열, 열노화와 해중합(解重合)을 일으켜 연화(軟化) 재생되어 신생고무와 혼합하여 고무제품을 생산하고 있으나, 이 천연고무 재생방법도 유기약품과 기름 등을 일정한 압력 하에서 상기 고온을 유지하여 몇 시간 동안 가열하는 방법이어서 에너지 측면에서 바람직한 방법이라고는 할 수 없으며 또 반드시 신생고무와 혼합함으로써만이 통상의 고무제품에서 요구하는 물성을 충족시킬 수 있었다.The tires of large-sized buses and trucks based on natural rubber are pulverized and then mixed with regenerant, heated to about 200 ° C, thermally aged and depolymerized, softened and regenerated to be mixed with new rubber. Although the product is produced, this natural rubber regeneration method is also a method of heating the organic chemicals and oil under a certain pressure to maintain the high temperature for several hours, which is not a desirable method in terms of energy, and must be mixed with the new rubber. Only could meet the physical properties required for ordinary rubber products.
게다가, 상기 방법은 천연고무에 국한되며 2차대전 후 널리 사용되고 있는 합성고무 가황물(加黃物)을 연화 재생시키지는 못하였다. 특히 합성고무의 대표적 고무인 스티렌-부타디엔 고무(styrene-butadiene rubber:SBR)를 주제로 한 소형 타이어의 폐고무는 가열하면 열노화, 해중합을 일으키지 않고 가교반응을 일으키기 쉽기 때문에 연화 재생되지 않고 경화되는 현상을 나타내므로 재생이 불가능하였다.In addition, the method was not limited to natural rubber and did not soften and regenerate synthetic rubber vulcanizates, which are widely used after World War II. In particular, the waste rubber of small tires based on styrene-butadiene rubber (SBR), which is a representative rubber of synthetic rubber, hardens without being softened and regenerated because it is easy to cause cross-linking reaction without heating and depolymerization when heated. It was not possible to play back.
이러한 단점을 해결하여 합성고무를 재생화시키기 위하여 국내외 관련 업체 및 연구소에서 많은 연구를 진행하고 있으며, 그 중 대표적으로 알려진 한 방법으로는 일본에서 개발된 것으로 스티렌-부타디엔 고무를 무산소 존재 하에서 약200℃ 온도로 가열할 경우 합성고무가 부드러워진다는 사실은 알게 되었으나 활용될 수 있는 품질의 재생고무는 얻을 수 없어 실용화되지는 못하였다.In order to solve these drawbacks, many researches have been conducted by domestic and foreign companies and research institutes to regenerate synthetic rubber, and one of the known methods is developed in Japan, where styrene-butadiene rubber is about 200 ° C It has been found that the synthetic rubber becomes soft when heated to temperature, but the recycled rubber of the quality that can be utilized cannot be obtained, and thus it has not been put to practical use.
또 한 일례로는 페닐히드라딘과 염화철(Ⅱ)의 복합체로 처리하면 천연고무는 물론 합성고무가 각종 가황물의 가교구조에 무관하게 실온에서 쉽게 연화 재생되는 것으로 밝혀졌으나 얻어진 연화재생고무를 재차 가황하여 제조할 경우 최종 생성되는 탄성체의 인장강도, 신장률, 인장응력 등의 물성이 현저히 낮아져서 실제 사용하기에는 만족스럽지 못하였다.For example, when treated with a complex of phenylhydradine and iron (II) chloride, natural rubber as well as synthetic rubber were found to be easily softened and recycled at room temperature irrespective of the crosslinked structure of various vulcanized products. When manufactured, the physical properties such as tensile strength, elongation rate, and tensile stress of the resulting elastic body were significantly lowered, which was not satisfactory for practical use.
본 발명은 상기 종래의 문제점 해결하기 위해 안출된 것으로, 폐타이어 등에서 나오는 폴리에스테르섬유를 신발 창이나 타이어 제조 후 폐기되는 천연고무 및 합성고무는 물론 네오프렌 또는 코르크와 혼합하여 강도와 내구성 및 탄성 등의 물성을 한층 드높인 물품을 제공하는 것을 그 목적으로 한다.The present invention has been made in order to solve the above problems, the polyester fibers from the waste tires, such as natural rubber and synthetic rubber discarded after the production of shoe soles or tires, as well as neoprene or cork, such as strength and durability and elasticity It is an object to provide an article having higher physical properties.
본 발명의 또 다른 목적은 우수한 방음효과, 방진효과 및 단열효과가 있어 건축자재로 이용될 수 있을 뿐 아니라 버려지는 폐물을 이용함으로써 환경을 보호하고 경제성을 높일 수 있는 폐폴리에스테르섬유를 함유하는 산업자재용 시이트를 제공하는 것이다.It is another object of the present invention to provide excellent soundproofing, dustproofing, and insulating effect, which can be used as a building material, as well as an industry containing waste polyester fiber that can protect the environment and improve economics by using waste products. It is to provide a sheet for the material.
본 발명에 따른 폐폴리에스테르섬유를 함유하는 산업자재용 시이트는 톨루엔에 액화시킨 합성고무 또는 천연고무(natural rubber)를 폐폴리에스테르섬유와 혼합, 교반, 건조시켜 롤러 상에서 시이트로 만든 다음, 프레스 압착하거나 컨베이어 상을 통해 몰드 성형하여 이루어지는 것을 특징으로 한다.Industrial material sheet containing waste polyester fiber according to the present invention is a synthetic rubber or natural rubber liquefied in toluene mixed with the waste polyester fiber, stirred, dried to make a sheet on a roller, press-pressed Or by molding the mold through a conveyor.
본 발명의 폐폴리에스테르섬유를 함유하는 산업자재용 시이트는 상기 합성고무가 클로로프렌(chloroprene) 또는 클로로프렌공중합체인 네오프렌(neoprene)인 것을 특징으로 한다.Industrial material sheet containing the waste polyester fiber of the present invention is characterized in that the synthetic rubber is chloroprene (neoprene) or chloroprene copolymer.
합성고무는 클로로프렌과 클로로프렌공중합체가 있는데, 이소프렌 μ- 및 α-이소프렌 중합체가 합성고무로서 적당하며 이중 현재 시판되고 있는 것은 클로로프렌고무 또는 이것에 소량의 다른 단위체를 중합시킨 네오프렌(상품명)으로 네오프렌GN, 네오프렌RT, 네오프렌FR, 네오프렌Q 등이 있다.Synthetic rubbers include chloroprene and chloroprene copolymers, and isoprene μ- and α-isoprene polymers are suitable as synthetic rubber, and currently commercially available neoprene GN is a neoprene (trade name) polymerized with chloroprene rubber or a small amount of other monomers. , Neoprene RT, neoprene FR, neoprene Q and the like.
본 발명의 폐폴리에스테르섬유를 함유하는 산업자재용 시이트를 만들기 위하여, 합성고무 또는 천연고무를 톨루엔에 혼합하여 액화시킨다. In order to make the sheet for industrial materials containing the waste polyester fiber of this invention, synthetic rubber or natural rubber is mixed with toluene and liquefied.
이때, 합성고무로서 네오프렌을 사용할 경우 톨루엔에 녹이기에 가장 바람직한 비율은 네오프렌:톨루엔이 2:8 또는 3:7이다. In this case, when neoprene is used as the synthetic rubber, the most preferable ratio for dissolving in toluene is 2: 6 or 3: 7 of neoprene: toluene.
상기 합성고무 또는 천연고무를 톨루엔에 넣어 액화시킬 때, 난연제(難燃劑)를 첨가하여 난연가공(難燃加工)을 한다. 이와 같은 난연가공은 가연성(可燃性)의 섬유를 완전하게 불연화(不燃化)하기는 곤란하지만, 착화성이나 불꽃을 일으켜 번져가는 연소성을 저하시켜 가연성을 방지하기 위한 것이다.When the synthetic rubber or natural rubber is liquefied in toluene, a flame retardant is added to perform flame retardant processing. Such flame retardant processing is difficult to completely inflammable combustible fibers, but is intended to prevent flammability by lowering flammability due to flammability and sparks.
본 발명의 폐폴리에스테르섬유를 함유하는 산업자재용 시이트에 사용되는 난연제로는 데카브롬(Br), 산화안티몬Ⅲ(Sb2O3), 수산화알루미늄(Al(OH)3) 등이 바람직하다.Flame retardants to be used in industrial material sheet for containing a waste polyester fibers of the present invention include decanoic bromine (Br), antimony oxide Ⅲ (Sb 2 O 3), aluminum hydroxide (Al (OH) 3) is preferred.
상기 톨루엔에 액화시킨 합성고무 또는 천연고무와 난연제가 첨가된 액상혼합물에 폐폴리에스테르섬유를 혼합한다. 이때, 혼합되는 폐폴리에스테르섬유는 분말상을 사용하며, 상기 액상혼합물과 분말 폐폴리에스테르섬유는 3:7 중량비로 혼합하는 것이 바람직하다.The waste polyester fibers are mixed with a liquid mixture in which the synthetic rubber liquefied in toluene or natural rubber and a flame retardant are added. At this time, the waste polyester fibers to be mixed are used in powder form, and the liquid mixture and the powdered waste polyester fibers are preferably mixed in a weight ratio of 3: 7.
여기서, 상기 혼합되는 폐폴리에스테르섬유는 표백단계를 거치거나 그렇지 않은 것을 모두 사용할 수 있는데, 표백된 폐폴리에스테르섬유를 사용할 경우 비중이 월등히 가벼워진다. 따라서, 표백된 폐폴리에스테르섬유를 사용하여 만들어진 산업자재용 시이트는 비중이 훨씬 가볍고 특히 다채로운 색상을 낼 수 있는 장점이 있다.Here, the mixed waste polyester fibers can be used through all bleaching step or not, the specific gravity is significantly lighter when using the bleached waste polyester fibers. Therefore, the sheet for industrial materials made using the bleached waste polyester fiber has the advantage that the specific gravity is much lighter, and in particular can produce a variety of colors.
상기와 같이 혼합된 분말 폐폴리에스테르섬유와 액상혼합물을 혼련 및 교반시킨 다음 건조시킨다. 상기 건조단계에서 상기 폐폴리에스테르섬유와 액상혼합물 사이에는 그 자체의 응집력이 생긴다.The powdered waste polyester fiber and the liquid mixture mixed as described above are kneaded and stirred, and then dried.
