아크릴수지 조성물 및 이의 제조방법{A acrylic resin composition and the method of manufacturing thereof}A acrylic resin composition and the method of manufacturing thereof

본 발명은 아크릴수지 조성물 및 이의 제조방법에 관한 것으로, 보다 상세하게는 환경오염이 예방되고, 인체에 무해한 아크릴수지를 제조하되, MMA(Methyl Methacrylate), BMA(n-Butyl Methacrylate), IBMA(iso-Butyle Methacrylate), EDMA(Ethyleneglycol Dimethacrylate)와 같은 아크릴수지를 소정의 중량비로 배합하여 상기 아크릴수지를 용해 반응시킬 수 있는 용제로 교반 반응시켜 인체 및 환경에 무해한 가소제에 용해되도록 함으로써 환경호르몬 의심물질로 인해 환경문제로 대두되는 PVC(Polyvinyl Chloride)를 대체할 수 있는 아크릴수지 조성물 및 이의 제조방법에 관한 것이다.The present invention relates to an acrylic resin composition and a method of manufacturing the same, and more particularly, to prevent environmental pollution, to produce an acrylic resin harmless to the human body, MMA (Methyl Methacrylate), BMA (n-Butyl Methacrylate), IBMA (iso -By mixing acrylic resins such as Butyle Methacrylate) and EDMA (Ethyleneglycol Dimethacrylate) in a predetermined weight ratio and stirring them with a solvent capable of dissolving the acrylic resin, it is dissolved in a plasticizer that is harmless to humans and the environment. The present invention relates to an acrylic resin composition capable of replacing PVC (Polyvinyl Chloride) due to environmental problems and a method of manufacturing the same.

석유화학공업의 발달로 현대를 살아가는 인류의 일상생활에 비닐, 플라스틱 등을 이용한 합성수지제품이 다양한 생활용품으로 제조되고 있는데, 이러한 합성수지제품들은 사용자들에게 주는 편리함 등의 많은 장점에도 불구하고, PVC제품 및 가소제 제조업체들이 환경호르몬 의심물질을 유아용 완구, 식품 포장재, 착유기 호스 등의 원료로 사용하고 있어 국민건강에 심각한 위협을 초래하고 있다.Synthetic resin products using vinyl, plastic, etc. are manufactured into various household products in the daily life of the human beings who live in modern times due to the development of petrochemical industry. These synthetic resin products are made of PVC products despite many advantages such as convenience to users. And plasticizer manufacturers are using environmental hormone suspected substances as raw materials for infant toys, food packaging materials, milking machine hose, etc., causing serious threats to national health.

상기 석유화학제품은 1869년 미국의 하이아트가 발명한 셀룰로이드로부터 시작된 이후 많은 발전을 거듭하여 페놀수지, 요소수지, 스틸렌수지, 초산비닐수지, 염화비닐수지, 폴리에틸렌, 폴리에스테르 등의 다양한 합성수지가 개발이 되고 있는데, 특히 가장 많이 사용되고 있는 화학제품이 PVC이며, 이러한 PVC제품의 경우는 창틀과 축음기판 등과 같이 경질의 PVC 뿐만 아니라 피혁 대용품, 비닐커튼, 전기줄 피복제, 음식용기 덮개용 랩 필름 등과 같은 연질의 PVC로 일상생활에 다양하게 사용되어 지고 있다.Since the petrochemical products started from the celluloid invented by Hiart in the United States in 1869, a lot of developments have been made, and various synthetic resins such as phenol resin, urea resin, styrene resin, vinyl acetate resin, vinyl chloride resin, polyethylene, and polyester have been developed. In particular, the most commonly used chemicals are PVC, which is not only hard PVC such as window frames and gramophones, but also soft substitutes such as leather substitutes, vinyl curtains, wire coatings, and food container cover films. PVC is widely used in daily life.

상기 PVC제품이 유연성을 가지도록 하기 위해서는 DOP((Dioctyl Phthalate), DOA(Dioctyl Adipate) 등의 가소제를 사용하는데, 이러한 가소제의 작용을 간단히 살펴보면, PVC는 긴 끈 같은 분자가 모여서 된 것으로, 분자 사이에 서로 끌어당기는 힘이 강할수록 경질의 성질을 가지게 되며, 상기 분자 사이에 가소제가 끼어들면 분자 사이의 직접 끌어당기는 힘이 약해져 잘 휘게 되는 연질의 성질을 가지게 되어 다양한 제품으로 사용되어 지고 있다.In order to make the PVC product flexible, plasticizers such as DOP ((Dioctyl Phthalate) and DOA (Dioctyl Adipate) are used, and if you look at the action of these plasticizers, PVC is a collection of long string-like molecules. The stronger the attracting force to each other has a harder property, and when the plasticizer is inserted between the molecules, the direct pulling force between the molecules is weakened, so that the soft property is well bent and is used in various products.

상기 PVC제품은 환경호르몬, 산성비, 발암물질 등의 환경문제로 인해 선진국에서는 규제를 하고 있으며, 이에 대한 대체 화학제품으로 인체에 무해한 아크릴수지에 대한 필요성이 대두하게 되는데, 상기 아크릴수지는 투명성, 성형성, 가공성 및 내후성이 뛰어나며, 색조의 종류가 풍부하며, 비중이 가벼운데 비해 강인성은 무기강화 유리에 필적하고 특히 뜨거운 것에는 무기강화 유리보다 격단과 충격에 대해 강하며, 인체에 독성을 미치지 않아 식기, 광고자재, 인테리어용품 등은 물론 의자, 인공뼈 등의 다양한 분야에 사용되어 지고 있다.The PVC products are regulated in developed countries due to environmental problems such as environmental hormones, acid rain and carcinogens, and the need for acrylic resins, which are harmless to humans, has emerged as an alternative chemical product. It has excellent properties, processability and weather resistance, is rich in color tone, and has a low specific gravity, but toughness is comparable to that of inorganic tempered glass. It is used in various fields such as tableware, advertisement materials, interior goods, chairs, artificial bones, and the like.

하지만 종래의 아크릴수지는 상기와 같은 우수한 특성에 비해 가소제에 용해가 되지 않기 때문에 일상생활에서 많이 사용되고 있는 연질의 합성수지 제품 즉, 유아용 완구, 식품 포장재 등의 경우에는 가소제에 용해가 용이한 PVC제품을 사용하고 있어 사용자들은 환경호르몬 물질에 의한 위험에 그대로 노출되어 건강에 심각한 손상을 주게 되며, 아크릴수지가 가소제에 용해가 되지 않아 경질의 제품에만 사용되어 질 수 밖에 없어 아크릴수지에 대한 효용성이 저하된다는 문제점이 있다.However, conventional acrylic resins do not dissolve in plasticizers as compared to the above excellent properties. Therefore, in the case of soft synthetic resin products that are frequently used in daily life, such as infant toys and food packaging materials, PVC products which are easily dissolved in plasticizers are used. Users are exposed to the dangers of environmental hormone substances, causing serious damage to their health, and acrylic resins are not dissolved in plasticizers, so they can only be used for hard products. There is a problem.

상기와 같이 가소제에 용이하게 용해되는 아크릴수지 조성물을 구성하는 아크릴수지의 성분과 배합비율을 보면, MMA, BMA, IBMA, EDMA를 소정의 중량비로 적정하게 배합되게 하되, MMA 〉BMA 〉IBMA 〉EDMA의 중량비로 적어도 하나 이상 선택적 및/또는 복합적으로 배합이 이루어지도록 한다.As described above, the components and blending ratios of the acrylic resin constituting the acrylic resin composition easily dissolved in the plasticizer allow MMA, BMA, IBMA, and EDMA to be appropriately blended at a predetermined weight ratio, but MMA> BMA> IBMA> EDMA At least one or more of the weight ratios of the combinations and / or combinations to be made.

이하, 본 발명에 의해 구성되는 아크릴수지 조성물의 실시례를 살펴보면, 다음과 같다.Hereinafter, looking at an embodiment of the acrylic resin composition constituted by the present invention, are as follows.

상기 아크릴수지의 배합비율은 어느 정도의 일정범위 내에서 배합비율의 조정이 가능한데, 통상적으로 MMA는 40∼50 중량%, BMA는 25∼35 중량%, IBMA는 20∼30 중량%, EDMA는 1∼10 중량% 내에서 적정하게 배합하여 아크릴수지의 연질정도를 조절할 수 있도록 하며, 연질정도의 품질이 우수한 최적 배합비율을 보면, MMA는 46.87 중량%, BMA는 28.49 중량%, IBMA는 22.78 중량%, EDMA는 1.86 중량%으로 조성될 때 연질정도의 품질이 가장 우수하다.The blending ratio of the acrylic resin can be adjusted within a certain range to some extent, typically 40 to 50% by weight MMA, 25 to 35% by weight BMA, 20 to 30% by weight IBMA, 1 EDMA It is possible to adjust the softness of acrylic resin by appropriately mixing within ~ 10% by weight, and the optimum blending ratio with excellent softness is 46.87% by weight for MMA, 28.49% by weight for BMA, and 22.78% by weight for IBMA. EDMA has the best soft quality when formulated at 1.86 wt%.

상기 아크릴수지들 중에 임의의 2개나 3개를 선택적으로 배합 반응하여 아크릴수지 조성물을 제조할 수도 있지만, 이러한 경우에는 상기 아크릴수지 조성물의연질정도의 품질이 저하되는 문제점이 발생하므로 4개의 아크릴수지를 복합적으로 배합 반응하여 아크릴수지 조성물을 제조하는 것이 바람직하다.The acrylic resin composition may be prepared by selectively mixing any two or three of the acrylic resins, but in this case, the quality of the softness of the acrylic resin composition may be degraded.
