일반적으로 석유화학 제품인 합성수지는 내약품성, 투명성, 유연성 및 강도 등의 물성이 우수하여 여러 분야에서 광범위하게 사용되고 있으나, 사용 후에 환경을 오염시키고 소각하는 경우에는 유독성 물질이 발생된다는 문제점이 있다.Generally, synthetic resins, which are petrochemical products, have excellent physical properties such as chemical resistance, transparency, flexibility, and strength, but are widely used in various fields. However, there is a problem that toxic substances are generated when the environment is polluted and incinerated after use.
이러한 문제점을 해결하기 위하여 분해성 수지가 개발되고 사용되고 있으나, 이러한 분해성 수지는 가격이 고가라는 문제점이 있다.Degradable resins have been developed and used to solve this problem, but such degradable resins have a problem of high price.
따라서 본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 창안한 것으로서, 본 발명의 목적은 환경을 덜 오염시키면서도, 일반수지에 비하여 저렴하게 생산할 수 있는 수지조성물을 제공하는 데 있다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to provide a resin composition which can be produced inexpensively as compared to a general resin while less polluting the environment.
이러한 상기 목적은 본 발명에 의해 달성되며, 본 발명의 일면에 따라 왕겨를 이용한 친환경 수지조성물은 합성수지와 전분 및 첨가제로 구성되는 수지조성물이 구비되고, 합성수지 100중량부에 대하여 왕겨분말 55~60중량부, 옥수수 전분 20~30중량부를 혼합하여 조성된 것을 특징으로 한다.This object is achieved by the present invention, eco-friendly resin composition using chaff according to an aspect of the present invention is provided with a resin composition consisting of synthetic resin and starch and additives, rice husk powder 55 ~ 60 weight based on 100 parts by weight of synthetic resin Part, characterized in that the composition was formed by mixing 20 to 30 parts by weight of corn starch.
그리고 상기 왕겨분말은 120~130℃에서 교반되어 건조되고, 상기 합성수지 100중량부에 대하여 납(Pb)이 포함되지 않은 무독안정제 3~5중량부가 추가로 포함되는 것을 특징으로 한다.And the chaff powder is stirred and dried at 120 ~ 130 ℃, characterized in that 3 to 5 parts by weight of a non-toxic stabilizer that does not contain lead (Pb) is added to 100 parts by weight of the synthetic resin.
또한 상기 합성수지에는 글리세린, 에틸렌디글리콜, 4-부탄디올 등을 단독 또는 혼합하여 가소제로 사용되는 것을 특징으로 한다.In addition, the synthetic resin is characterized in that it is used as a plasticizer alone or mixed with glycerin, ethylene diglycol, 4-butanediol.
이하 본 발명의 바람직한 실시예를 상술한다. 본 발명에 의한 왕겨를 이용한 친환경 수지조성물은 합성수지, 전분 및 왕겨분말 등으로 구성되는데, 상기 합성수지는 ABS수지, PP PE PS 하인백 등으로 구성될 수 있다.Hereinafter, preferred embodiments of the present invention will be described in detail. Eco-friendly resin composition using chaff according to the present invention is composed of synthetic resin, starch and chaff powder, etc., the synthetic resin may be composed of ABS resin, PP PE PS servant bag and the like.
상기 ABS수지는 아크릴로 니트릴, 부타디엔 및 스티렌의 3성분으로 이루어져 내충격성 열가소성 수지를 총칭하며 이들 세 성분의 머릿 글자를 취하여 ABC수지 혹은 ABC tert-폴리머(3원공중합체)라고도 불리는 수지이다. 이러한 ABC수지는 전기/전자분야, OA 및 통신기기분야 자동차 분야 등에 폭넓게 사용되고 있는 수지이다.The ABS resin is composed of three components of acrylonitrile, butadiene, and styrene to refer to impact-resistant thermoplastic resin collectively, and is a resin called ABC resin or ABC tert-polymer (terpolymer) by taking the head letters of these three components. The ABC resin is a resin widely used in the electric / electronic field, the OA and the automotive field.
그리고 상기 PP(폴리프로필렌)은 석유 분해 가스 속에 포함되어 있으며, 폴리에틸렌의 중합(重合)과 같이 순수하게 만든 프로필렌 가스를 용제 속에서 특수한 유기 금속의 촉매로 상온, 상압에서 중합하여 만든 수지로써 밀도는 플라스틱 중에 서도 가장 가볍고(0.90~0.91), 기계적 강도가 크며, 내열성이 우수하고 비교적 투명하다. 또 고주파의 유전 특성이 좋은 성질이 있다.In addition, the PP (polypropylene) is contained in petroleum decomposition gas, and the resin is made by polymerizing propylene gas, which is made purely like polymerization of polyethylene, in a solvent with a special organic metal catalyst at room temperature and atmospheric pressure. It is the lightest among plastics (0.90 ~ 0.91), has high mechanical strength, good heat resistance and relatively transparent. In addition, high-frequency dielectric properties are good.
상기 PE(polyethylene)는 에틸렌에서 만들어지는 합성수지로써 내수성과 내약품성이 뛰어나 그릇·포장 재료·전기 절연체·공업용 부품 따위에 널리 쓰이고 있고, 상기 PS(polystyrene)는 보통 2,000~3,000개의 방향족 탄화수소인 스티렌 분자들이 서로 화학 반응을 통해 결합되어 만들어지는 긴 사슬 분자로 이루어진 합성 유기 중합체이다. 폴리스티렌은 1930년대말에 대규모로 생산되기 시작했다. 일반적으로 스티렌은 비누에 의해 물에 분산되고, 중합반응은 자유 라디칼 촉매에 의해 개시된다. 값싸고 강한 열가소성(가열하면 연화되어 다른 모양으로 변화될 수 있는 성질) 수지인 생성물은 산·알칼리 및 많은 용매의 공격에 강하고 물을 흡수하지 않으며, 뛰어난 절연체이다. 폴리스티렌이 만들어지는 현탁액에 고무 유액을 첨가하면 충격에 매우 강하므로 1960년대 중반 미국에서는 이 방법으로 폴리스티렌의 반 이상을 만들었다. 폴리스티렌은 냉장고·공기조절장치 같은 대형 가정용품의 하우징을 만드는 데 이용되는 등 용도가 다양하다.The PE (polyethylene) is a synthetic resin made from ethylene and has excellent water resistance and chemical resistance, and is widely used in vessels, packaging materials, electrical insulators, and industrial parts. These are synthetic organic polymers consisting of long chain molecules that are formed by bonding together through chemical reactions. Polystyrene began to be produced on a large scale in the late 1930s. Generally styrene is dispersed in water by soap, and the polymerization is initiated by free radical catalyst. Products, which are inexpensive and strong thermoplastics (which can soften and change into other shapes when heated), are resistant to the attack of acids, alkalis and many solvents, do not absorb water, and are excellent insulators. The addition of rubber latex to suspensions from which polystyrene is made is extremely resistant to shock, so in the mid-1960s this method produced more than half of polystyrene. Polystyrene is used in a variety of applications, such as making housings for large household items such as refrigerators and air conditioners.
상기한 바와 같은 합성수지에 왕겨분말이 투입되는데 합성수지 100중량부에 왕겨분말 55~60중량부를 투입되며, 특히 상기 왕겨분말은 전조가 잘 되어 있어야 한다. 상기 왕겨분말에 습기가 있는 경우에는 사출/압출 과정에 불량이 이루어지므로 상기 왕겨분말은 열을 가할 수 있는 교반기에서 건조되는데, 상기 교반기의 온도는 120~130℃을 유지하도록 하고 소손(燒損)되는 일이 없도록 계속 교반시키면서 건조한다. 본 출원인이 왕겨를 합성수지에 혼합하는 과정에서 수 십번의 실패를 하 였으나 상술한 바와 같이 왕겨분말을 120~130℃에서 교반하면서 건조시킨 후에 합성수지에 혼합하면 사출/압출 성형이 잘 이루어진다는 것을 알게 되었다.The rice husk powder is added to the synthetic resin as described above, the rice husk powder is added 55 to 60 parts by weight to 100 parts by weight of the synthetic resin, in particular, the chaff powder should be well prepared. If there is moisture in the rice husk powder is bad in the injection / extrusion process, the rice husk powder is dried in a stirrer that can be heated, the temperature of the stirrer to maintain 120 ~ 130 ℃ and burn (燒損) Drying is continued while stirring to prevent any occurrence. Applicant has failed several times in the process of mixing the chaff into the synthetic resin, but it was found that the injection / extrusion molding is well performed when the chaff powder is mixed with the synthetic resin after drying with stirring at 120 ~ 130 ℃ as described above .
그리고 상기 합성수지 100중량부에 옥수수 전분 20~30중량부가 혼합되는데, 상기 옥수수 전분은 생분해성 원료로써 자연 분해할 수 있게 된다.In addition, 20 to 30 parts by weight of corn starch is mixed with 100 parts by weight of the synthetic resin, and the corn starch may be naturally decomposed as a biodegradable raw material.
또한 상기 조성물에는 안정제가 투입되는데 상기 안정제 중에는 납(Pb)이 함유된 것이 있다. 이와 같은 납은 자연을 오염시킬 뿐만 아니라 소각시에는 납이 공기 중에 퍼져서 인체에 흡수될 수 있게 된다.In addition, a stabilizer is added to the composition, but some of the stabilizers contain lead (Pb). This lead not only pollutes nature, but when incinerated, lead can be spread in the air and absorbed by the human body.
따라서 본 발명에 의한 조성물에는 납(Pb)이 포함되지 않은 안정제를 사용하게 된다. 예를 들어서 선경케미칼(주)에서 제조된 SKF-910S나 SK-910Sfmf 사용하게 된다. 위 제품에는 납(Pb)가 포함되지 않아서 환경이나 인체에 해를 끼칠 염려가 없게 된다.Therefore, the composition according to the present invention will use a stabilizer that does not contain lead (Pb). For example, SKF-910S or SK-910Sfmf manufactured by Sunkyung Chemical Co., Ltd. will be used. The product does not contain lead (Pb), so there is no danger of harming the environment or human body.
상기 합성수지에는 가소제를 추가하여 사용될 수 있는데, 상기 가소제로는 글리세린, 에틸렌디글리콜, 4-부탄디올 등을 단독 또는 혼합하여 사용되게 된다.The synthetic resin may be used by adding a plasticizer, and the plasticizer may be used alone or in combination with glycerin, ethylene diglycol, 4-butanediol, and the like.
본 발명의 상기와 같은 구성에 따라, 본 발명에 의한 수지조성물을 사용하거나 소각할 때에도 환경을 오염을 줄인 수 있는 친환경조성물이고, 일반 합성수지에 비하여 저렴하게 생산할 수 있게 되므로써 수지조성물의 상품성이 증대되게 된다.According to the configuration as described above of the present invention, even when using or incinerated the resin composition according to the present invention is an environmentally friendly composition that can reduce the environment, and can be produced inexpensively compared to general synthetic resins to increase the commerciality of the resin composition do.
이상에서 설명한 것은 본 발명에 따른 왕겨를 이용한 친환경 수지조성물을 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남 이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경실시가 가능한 범위까지 본 발명의 기술적 사상이 있다고 할 것이다.What has been described above is just one embodiment for carrying out the eco-friendly resin composition using chaff according to the present invention, the present invention is not limited to the above-described embodiment, the invention as claimed in the following claims Without departing from the gist of the present invention, any person having ordinary knowledge in the field of the present invention will have the technical idea of the present invention to the extent that various modifications can be made.
