Abstract
Description
본원은 무적성 고분자 물질 및 그의 제조방법에 관한 것이다.The present application relates to an invincible polymer material and a method for preparing the same.
좀더 구체적으로 기재하면, 고분자 필름을 표면처리한 것에, 수용성 단량체 혹은 수용성 고분자와 가교제를 용제에 용해한 것에, 도포하고 이를 자외선광으로 조사하면서 된 무적성 고분자 물질 및 그의 제조하는 방법에 관한 것이다.More specifically, the present invention relates to an invincible polymer material obtained by applying a surface of a polymer film to a solution of a water-soluble monomer or a water-soluble polymer and a crosslinking agent in a solvent, and irradiating it with ultraviolet light, and a method for producing the same.
고분자필름은 우수한 기계적 성질, 유연성, 무독성 광학적 성질등과 같은 유용한 물성때문에 광범위하게 쓰이고 있으나 이들이 갖는 표면성질이 좋지 않은 결점이 있다.Polymer films are widely used due to their useful properties such as excellent mechanical properties, flexibility and non-toxic optical properties, but they have defects in poor surface properties.
예를들면 농업용 비닐하우스의 경우에는 하우스내의 공기중에 존재하는 수증기가 필름과 고분자시트등의 표면에 맺혔을때 이 하우스의 투명도가 저하되며 따라서 작물의 생육을 방해하고 이 수적이 잎사귀, 발아중인 싹, 꽃잎 등에 낙하하면 이들이 고사하는 등의 폐단이 있다. 또 식품포장재표로서는 이 수적으로 인한 내용물의 부패 등의 변성이 촉진되는 결점이 있다.For example, in the case of agricultural vinyl houses, the transparency of the house is reduced when water vapor in the air in the house forms on the surface of film and polymer sheet, thus preventing the growth of crops, and the water droplets are germinating and sprouting. If they fall on petals, they will die. In addition, there is a drawback in the food packaging list that the degeneration of the contents, such as corruption, is promoted.
이러한 문제점의 해결책으로서 종래에는 특수계면 활성제의 도포, 무적제를 고분자 필름재와 혼련하는 방법, 방사선과 저온 플라즈마처리를 이용한 수용성 고분자의 그라프트 중합하는 방법, 자외선광처리에 의한 그라프트 중합 방법등이 있다.As a solution to this problem, there are conventionally applied a special surfactant, a method of kneading an uninhibiting agent with a polymer film material, a graft polymerization method of a water-soluble polymer using radiation and low temperature plasma treatment, a graft polymerization method by ultraviolet light treatment, and the like.
이중 특수계면활성제의 도포법은 무적제를 함유한 층의 두께가 얇아서 흡수능이 적고, 내구성이 짧은 것이 흠이다.The application method of the special surfactant is that the thickness of the layer containing the invincible agent is thin, so that the absorption capacity is low and the durability is short.
이 특수계면활성제는 친수성 계면활성제등이 사용되고 있으나 실제사용시 필름표면 부착부분의 수적과의 유하가 동반되어 무적제가 용이하게 유실된다. 따라서 이들 모두 초기의 효과는 우수하나 지속성이 극히 나쁜 결점이 있다.Hydrophilic surfactants are used for this special surfactant, but in actual use, it is accompanied by a drop of water on the surface of the film attachment part, so that the uninhibiting agent is easily lost. Therefore, all of them have a good initial effect but extremely poor sustainability.
또 무적제를 고분자 필름과 혼련하는 방법은 사용수지와 무적제와의 상용성이 나빠서 필름표면에 무적제가 방출됨으로 인하여 불루밍현상이 야기되어 불투명 해지기 쉽고 이로 인하여 태양광이 불균일하게 투과하는 등이 현상이 일어난다. 이러한 현상은 상용성이 양호한 무적제를 선정하면 피할 수 있으나 이 무적제가 친수성을 가져야 하므로 필름표면에 존재하면 수적에 의해 용출이 되고, 이렇게 되면 무적성능이 저하되고 불루밍 현상은 다시 일어난다. 즉 이 혼합형 필름의 경우, 정도에 따라서 불루밍 현상은 필수불가결하게 동반이 된다.In addition, the method of kneading an invincible agent with a polymer film has a poor compatibility between the resin and the invincible agent, which causes bulging phenomenon due to the release of the invincible agent on the surface of the film. This happens. This phenomenon can be avoided by selecting an invincible agent having good compatibility, but since the invincible agent should have hydrophilicity, it is eluted by water droplets when present on the surface of the film. That is, in the case of this mixed film, the blooming phenomenon is inevitably accompanied depending on the degree.
방사선과 저온 플라스마 처리를 이용하여 수용성 고분자를 필름에 그라프트 중합하는 방법은 처리효과가 크며 처리효과의 다양성이 넓다는 강점이 있으나 초기설비비가 아주 크며, 작업성 생산성이 감소한다는 결점이 있어 실용화는 아직도 어려운 실정이다. 이에 반하여 자외선 광에 의한 고분자필름에 그라프트 중합하는 방법은 위의 방사선과 저온 플라스마 중합보다 간단하여 인쇄적성이나 접착성등의 성질을 개량시키는 목적에는 비교적 유용하게 쓰인다. 이들 그라프트 중함만으로는 농업용필름에 적용되기에는 수적과 기타 주위 환경에 대하여 내구성이 약한 것이 결정적인 취약점이다.Graft polymerization of water-soluble polymers into films using radiation and low-temperature plasma treatment has the advantages of greater treatment effect and wider variety of treatment effects, but the disadvantages of high initial equipment cost and reduced productivity of workability. It is difficult. On the other hand, the method of graft polymerization on the polymer film by ultraviolet light is simpler than the above radiation and low temperature plasma polymerization, which is relatively useful for the purpose of improving the properties such as printability and adhesion. These graft weights are the only weaknesses in water droplets and other environmental conditions that cannot be applied to agricultural films.
따라서 본 발명에서는 광을 사용하여 광개시제로 수용성 단량체를 그라프트중합하고 동시에 가교하는 방법으로서 극히 우수한 무적성을 갖는 폴리올레핀 필름을 제공하여 이의 방법은 연속적, 저렴한 투자 설비비, 제조법이 용이하다는 특성이 있다. 또한 이의 도포막의 두께가 1μ 이하이며 전체적인 무게증가가 거의 없다.Therefore, the present invention provides a polyolefin film having extremely excellent invincibility as a method of graft polymerization and crosslinking a water-soluble monomer with a photoinitiator using light, and the method has the characteristics of continuous, low-cost investment cost, and easy manufacturing method. In addition, the thickness of the coating film thereof is 1 μm or less, and there is almost no increase in the overall weight.

실시예와 비교예에 대한 표면처리된 각 필름의 접촉각의 변화와 수적에 대한 내구성 표Durability Table for Changes and Drops in Contact Angle of Each Surface Treated Film for Examples and Comparative Examples
표 1의 실시예 1~11에서는 처리후의 접촉각이 20˚~0˚이어서, 필름의 표면에 수적이 전혀 생기지 아니하고, 또한 내구성이 우수함을 알 수 있고, 비교예 1~2에서는 처리후의 접촉각이 처리전의 접촉각과 거의 같은 것이어서 수적이 생기며, 또한 내구성이 아주 없음을 알 수 있다.In Examples 1 to 11 of Table 1, the contact angle after the treatment was 20 ° to 0 °, so that no water droplets occurred on the surface of the film, and the durability was excellent. In Comparative Examples 1 to 2, the contact angle after the treatment was treated. It is almost the same as the previous contact angle, so that water droplets are generated, and it can be seen that the durability is very low.
무적성이 부여된 고분자 물질이 신물질임을 확인하기 위하여 실시예 5의 무적성 필름을 끓는 물에 1시간 동안 미반응물을 추출시켰다.In order to confirm that the polymer material given invincibility is a new substance, the invincible film of Example 5 was extracted with boiling water for 1 hour.
건조한 필름을 ATR-IR로 찍은것이 그림 1과 같다.A dry film taken with ATR-IR is shown in Figure 1.
스펙트럼에서 보듯이 1718cm-1에서 강한 -COOH 스트레칭 피크가, 1370~ 1030cm-1에서 증폭된 아크릴산의 피크가 나타내여 그라프된 폴리에틸렌 필름으로서 신물질임을 확인하였다.As shown in the spectrum was identified as a strong -COOH stretching peak at 1718cm -1, 1370 ~ 1030cm -1 as a peak of the amplified acrylic acid shown in the open grafted polyethylene film (ICT).
