Description
본 발명은 영구적인 대전방지성을 갖는 아크릴수지 패널의 제조방법에 관한 것으로, 더욱 구체적으로는 내구성이 강한 정전기 방지 화합물을 아크릴수지 패널의 중합원료에 첨가하여 영구적인 정전기 방지성을 발휘할 수 있는 아크릴 수지 패널의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing an acrylic resin panel having a permanent antistatic property, and more particularly, an acrylic that can exhibit permanent antistatic properties by adding a durable antistatic compound to the polymerization raw material of the acrylic resin panel. It relates to a method for producing a resin panel.
일반적으로 대전방지제는 고분자 재료에 대전되는 정전기를 재빠르게 누설시키기 위한 목적으로 첨가된다. 섬유 플라스틱 등의 고분자 재료는 보통1013Ω㎝ 이상의 고유저항을 가지기 위하여 마찰등에 의해 용이하게 플러스(+) 또는 마이너스( -)의 큰 정하중을 띄게 되는 것으로 알려져 있다.In general, antistatic agents are added for the purpose of quickly leaking the static electricity charged on the polymer material. Polymeric materials such as fiber plastics are known to have a large positive load of positive (+) or negative (-) easily by friction in order to have a specific resistance of 10 13 Ωcm or more.
통상 폴리메타크릴수지판은 그 고유저항이 1015Ω㎝ 이상이다. 대전방지제는 높은 고유저항을 가진 고분자 물질의 저항을 1010Ω㎝ 정도 이하로 하는 것을 목적으로 해서 첨가하고 있다. 이 대전현상은 사람이 접촉했을 경우 쇼크를 받기도 하고 심할때는 불꽃 방전으로 인하여 화재의 원인이 되기도 한다. 또한 공기중의 먼지를 흡착하여 쉽게 떨어지지 않는다거나 그 위에 흡착량을 증가시켜 심하게 미관을 해치므로서 상품가치 뿐만 아니라 사용시의 불쾌감을 증가 시키기도 한다. 두가지 물질을 마찰시키면 양 물질간에 전자또는 이온의 이동이 일어나 전하가 발생한다. 고분자물질과 같은 절연체에서는 발생한 전하가 누설되지 않고 고분자 표면에 축적되어 여러형태의 정전기 적인 장해가 발생한다.Usually, the polymethacrylic resin board has a specific resistance of 10 15 Ωcm or more. An antistatic agent is added for the purpose of making the resistance of a high molecular material with a high specific resistance about 10 10 Ωcm or less. This charging phenomenon is shocked when a person comes in contact, and in severe cases, it may cause a fire due to spark discharge. In addition, it does not easily fall off by adsorbing dust in the air, or increases the amount of adsorption on it, which severely hurts the beauty, thereby increasing not only the value of the product but also the discomfort in use. Friction between two materials causes electrons or ions to move between them, creating a charge. In insulators such as polymer materials, the generated charges do not leak and accumulate on the surface of the polymer, causing various types of electrostatic disturbances.
일반적으로 폴리메틸메타크릴레이트로 된 아크릴수지 패널의 제조방법으로 압출방식과 캐스팅방식이 사용되고 있으며, 이들에 대한 대전방지방법으로는 제조된 패널에 대한 표면도포법과, 첨가하여 이겨넣기(직접첨가) 하는 방법이 있는 데 이중에서 주로 표면도포법이 사용되고 있으나, 이 표면도포법은 지속성이 떨어지고 내열성이 낮아 가공시에 문제가 되는 단점을 가지고 있다. 또, 이겨넣기(직접첨가)하는 방법은 투명을 요하는 아크릴수지와 같은 재질에서는 투명성이 소실되는 문제점이 있다. 현재 대전방지효과의 지속성이 양호한 투명고분자 재료의 대전방지는 대단히 어렵고 현재 그와 같은 목적으로 개발되어 있는 이겨넣기(직접첨가) 하는 대전방지는 없고 하나의 과제로 되어있다.In general, extrusion and casting methods are used as a method for producing an acrylic resin panel made of polymethyl methacrylate, and as an antistatic method therefor, the surface coating method for the manufactured panel, and the addition and tearing (direct addition) The surface coating method is mainly used, but the surface coating method has a disadvantage in that it is problematic in processing due to low durability and low heat resistance. In addition, the method of tacking (direct addition) has a problem in that transparency is lost in a material such as acrylic resin requiring transparency. At present, the antistatic effect of transparent polymer material with good sustainability of antistatic effect is very difficult, and there is no antistatic, which is currently being developed for such purpose, and it is a problem.
본 발명의 목적은 캐스팅 방법으로 제조되는 아크릴 수지에 하기한 화학식(1) ,(2),(3),(4)로 표시되는 대전방지 성능을 가지는 혼합액을 첨가하고 예비 중합시키는 단계를 거쳐 유리판의 사이에서 최종적으로 중합하여 경화되는 투명성이 뛰어나고 가공성이 양호하며 대전방지 효과가 우수하고 영구적인 대전방지성을 갖는 아크릴수지 패널의 제조방법을 제공하는 데 있다.An object of the present invention is to add a mixed solution having an antistatic performance represented by the following formulas (1), (2), (3), and (4) to an acrylic resin produced by a casting method, and then to pre-polymerize the glass plate. The present invention provides a method for producing an acrylic resin panel having excellent transparency to be finally polymerized and cured, having good workability, excellent antistatic effect, and permanent antistatic property.

본 발명에서는 촉매 존재하에서 메틸 메타크리레이트(Methl methacrylate : MMA ; MMA) 100% 중량부에 대하여 상기 화학식(1),(2),(3),(4)로 표시되는 화합물을 2∼10% 중량부로 첨가하고, 100℃에서 1∼3시간 중합반응을 실시하여 적절한 점도로 되었을 때 반응을 중지하여 예비중합 공정을 수행한다. 예비중합 공정의 종결시점은 중합된 수지의 점도가 캐스팅 작업을 할수 있을 정도의 적절한 점도로 한다.In the present invention, 2 to 10% of the compounds represented by the formulas (1), (2), (3) and (4) based on 100% by weight of methyl methacrylate (MMA; MMA) in the presence of a catalyst The mixture is added in parts by weight, and the polymerization is carried out at 100 ° C. for 1 to 3 hours to stop the reaction when the viscosity is appropriate and the prepolymerization step is performed. The termination point of the prepolymerization process is such that the viscosity of the polymerized resin is suitable for casting.
상기에서 대전방지제로 사용된 화학식(1),(2),(3),(4)의 글리세린지방산 모노에스테르, 솔비탄지방산 모노에스테르의 에틸렌옥사이드 축합물, 4급암모늄, 폴리에틸렌글리콜 모노지방산에스테르는 각각이 정전기 발생을 억제할 목적으로 사용될수 있으나 단독으로 사용하거나, 적절한 함량으로 조성되지 않으면 아크릴수지에 사용시 대전방지성능은 발휘할수 있는 반면에 투명성이 저하하는 단점이 있으며 상기 화학식(1),(2),(3),(4)로 표시된 화합물이 적절한 조합으로 될 때 아크릴수지에 첨가되어 아크릴수지 패널을 제조시 대전방지성능이 우수하고 수지의 투명성이 손상되지 않는다. 화학식(1)로 표시되는 글리세린지방산 모노에스테르는 10∼30% 화학식(2)로 표시되는 솔비탄지방산모노에스테의 에틸렌옥사이드 축합물 20∼50%, 화학식(3)으로 표시되는 4급암모늄염 1∼20%, 화학식(4)로 표시되는 폴리에틸렌글리콜 모노지방산에스테르 30∼60%로 구성되며 화학식(1),(2),(3),(4)에서 n은 2∼20, x는 8∼20이 좋으며, 화학식(3)에서 R1, R2, R3은 탄소수 1∼18로 구성된다. 상기 화합물을 예비 중합된 아크릴 수지 조성물에 대하여 중량비 0.5∼10%가 되게 첨가한다. 그 중에서도 2∼6% 정도 첨가하는 것이 아크릴수지 패널의 투명도와 대전방지 효과에 있어서 좋다. 이렇게 얻은 예비중합된 수지조성물에 중합촉매를 용해시켜가스켓을 부착시킨 2매의 유리판 사이에 넣고 탈기시킨후, 50∼60에서 3∼5시간 100℃에서 1∼2시간 가열하여 중합된 대전방지성을 가지는 투명한 아크릴수지 패널을 얻게 된다. 화학식(1),(2),(3),(4)로 표시되는 대전방지제의 첨가방법 및 시기는 본 발명의 범주가 한정하는 것은 아니다.Ethylene oxide condensates of glycerin fatty acid monoesters, sorbitan fatty acid monoesters of formulas (1), (2), (3) and (4) used as antistatic agents, quaternary ammonium, polyethylene glycol monofatty acid esters Each of them may be used for the purpose of suppressing the generation of static electricity, but if used alone or not formed in an appropriate amount, the antistatic performance may be exhibited when used in acrylic resins, but the transparency may be lowered. When the compounds represented by 2), (3) and (4) are in an appropriate combination, they are added to the acrylic resin so that the acrylic resin panel is excellent in antistatic performance and the transparency of the resin is not impaired. Glycerin fatty acid monoester represented by the formula (1) is 10 to 30% ethylene oxide condensate of sorbitan fatty acid monoester represented by the formula (2) 20 to 50%, quaternary ammonium salts represented by formula (3) 1 to 20%, consisting of 30 to 60% of polyethylene glycol monofatty acid ester represented by formula (4), where n is 2 to 20 and x is 8 to 20 in formulas (1), (2), (3) and (4). Is good, and in formula (3), R 1 , R 2 , R 3 are composed of 1 to 18 carbon atoms. The compound is added in a weight ratio of 0.5 to 10% based on the prepolymerized acrylic resin composition. Especially, adding about 2 to 6% is good in transparency and antistatic effect of an acrylic resin panel. The antistatic property polymerized by dissolving the polymerization catalyst in the prepolymerized resin composition thus obtained was put between two glass plates attached with a gasket and degassed, followed by heating at 50 to 60 for 3 to 5 hours at 100 ° C. for 1 to 2 hours. A transparent acrylic resin panel is obtained. The method and timing of addition of the antistatic agent represented by the formulas (1), (2), (3) and (4) are not limited to the scope of the present invention.
실시예1Example 1
촉매존재 하에서 MMA 100%중량부에 상기 화학식(1),(2),(3),(4)로 표시되는 화학식의 적절한 비율로 된 대전방지제 4%를 첨가하여 용해시키고 100℃로 2시간 가량 가열하면서 예비중합을 실시하여 캐스팅 작업을 하기 용이할 정도의 적절한 점도로 되었을 때 반응을 중지하고 냉각한다. 그 다음 냉각된 수지액에 촉매를 용해시키고 가스켓을 부착시킨 2매의 유리판 사이에 넣고 탈기시킨후 50∼60℃에서 3∼5시간 100℃에서 1∼2시간 가열하여 투명성이 좋고 대전방지성이 뛰어난 대전방지용 아크릴 수지 조성물을 얻는다.In the presence of a catalyst, 4% of an antistatic agent in an appropriate proportion of the formulas represented by the formulas (1), (2), (3), and (4) was added to 100% by weight of MMA, and dissolved at 100 캜 for about 2 hours. The prepolymerization is carried out while heating to stop the reaction and cool down when the viscosity reaches a suitable viscosity to facilitate the casting operation. Then, the catalyst was dissolved in the cooled resin solution, placed between two glass plates attached with a gasket, degassed, and heated at 50 to 60 ° C. for 3 to 5 hours at 100 ° C. for 1 to 2 hours to provide transparency and antistatic properties. An excellent antistatic acrylic resin composition is obtained.
실시예2Example 2
촉매존재 하에서 MMA를 100℃로 가열하면서 2시간 예비중합 반응을 실시하여 캐스팅 작업을 하기 용이한 정도의 적절한 점도로 되었을 때 반응을 중지하고 냉각한다. 그 다음 냉각된 수지액에 화학식(1),(2),(3),(4)로 구성된 대전방지제 조성물을 첨가하고 촉매를 용해시켜 실시예1과 동일한 방법으로 실시한다.In the presence of a catalyst, the MMA is heated to 100 ° C. for 2 hours to carry out a prepolymerization reaction, and the reaction is stopped and cooled when it reaches an appropriate viscosity that is easy to cast. Then, an antistatic agent composition composed of the formulas (1), (2), (3) and (4) was added to the cooled resin solution, and the catalyst was dissolved in the same manner as in Example 1.
이와같이 본 발명은 후처리하여 얻어지는 표면도포용 대전방지 처리와는 달리 케스팅공정 중에 대전방지제를 첨가하여 공정이 늘어나는 단점이 해소되고 표면결점과 투명성을 손상시키지 않고 대전방지성이 부여되며 이렇게 하여 얻은 수지 조성물은 투명성이 뛰어나고 대전방지효과도 매우 우수한 등 그 효과가 매우 크다.As described above, the present invention, unlike the antistatic treatment for surface coating obtained by post-treatment, eliminates the disadvantage of increasing the process by adding an antistatic agent during the casting process, and provides an antistatic property without impairing surface defects and transparency. The composition is very large, such as excellent transparency and antistatic effect.
