본 발명은 대전방지를 위한 새로운 고분자 유기물 코팅재료에 관한 것으로서, 보다 구체적으로는 고분자 사슬중의 친수기에 의한 자기유화를 이용하여 제조한 수분산 폴리우레탄에 고분자 전해질을 첨가함으로써 전기전도성 재료를 별도로 첨가하지 않고도, 도포후 건조 도막의 표면저항을 109Ohms/square의 수준까지 낮출수 있는 새로운 대전방지 코팅 재료에 관한 것이다.The present invention relates to a novel polymer organic coating material for antistatic, and more specifically, by adding a polymer electrolyte to a water-dispersed polyurethane prepared by using a self-emulsification by a hydrophilic group in the polymer chain to add an electrically conductive material separately It is directed to a new antistatic coating material which can lower the surface resistance of a dry coating after application, to a level of 10 9 Ohms / square.

종래, 대전 방지 코팅 재료는 주로 전기전도성이 우수한 금속, 카본블랙, 전기 전도성 고분자 등을 고분자 코팅 재료에 분산시켜 제조하여 왔다.Conventionally, antistatic coating materials have been produced by dispersing mainly metals having excellent electrical conductivity, carbon black, electrically conductive polymers and the like in polymer coating materials.

그러나, 금속 또는 카본블랙을 첨가한 코팅 재료의 경우는 도포후 건조시 도막이 불투명하여 투명성을 요구하는 도료로서는 사용이 곤란하고, 물리적 성질이 만족스럽지 못하며, 폴리아닐린, 폴리티오펜 등과 같은 전기전도성 고분자를 첨가한 코팅 재료는 고분자 코팅재료와 상용성에 한게가 있고 투명도에 제한이 있으며 원료가격이 매우 고가여서 적용이 제한적이다.However, in the case of a coating material added with metal or carbon black, it is difficult to use a coating material that requires transparency due to the opacity of the coating film after application, and is not satisfactory in physical properties, and it is difficult to use an electrically conductive polymer such as polyaniline or polythiophene. The added coating material is limited in compatibility with the polymer coating material, there is a limitation in transparency, and the application of the coating material is limited because the raw material price is very expensive.

고분자 전해질은 일반적으로 가소제를 첨가하는 경우 전기전도성이 양호하고 대전방지 재료로도 응용이 가능하고 투명한 대전방지 코팅 재료가 될 수 있으나, 수분에 대한 취약성 때문에 대전 방지를 위한 표면 코팅 재료써는 부적합한 단점이 있다.Polymer electrolytes generally have good electrical conductivity when plasticizers are added, can be applied as antistatic materials, and can be transparent antistatic coating materials.However, due to the vulnerability to moisture, surface coating materials for antistatic properties are not suitable. have.

따라서 본 발명은 상기한 바와 같은 선행기술의 제반 문제점을 감안하여 대전방지성, 투명성 및 내수성이 우수한 새로운 대전방지코팅재료를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a new antistatic coating material having excellent antistatic property, transparency and water resistance in view of the above problems of the prior art.

상기한 과제를 해결하기 위한 연구에서 본 발명자는 특정 수분산 폴리우레탄에 고분자 전해질을 첨가하여 제조한 코팅 재료가 상기한 목적에 부합한다는 사실을 알게되어 본 발명을 완성하게 된 것이다.In the research for solving the above problems, the present inventors have found that the coating material prepared by adding a polymer electrolyte to a specific water-dispersed polyurethane meets the above object, thereby completing the present invention.

본 발명에 의하면 (a) 폴리올과 디이소시아네이트를 몰비로 1:2로 반응시켜 프리폴리머를 제조하는 단계, (b) 프리폴리머 중의 이온화될 수 있는 작용기를 중화시켜 이온화시키는 단계, (c) 이온화된 프리폴리머와 사슬연장제 및 물을 혼합하고 반응시켜 고형분 함량 40-50중량%의 수분산 폴리우레탄을 제조하는 단계, 및(d) 제조된 수분산 폴리우레탄과 고분자 전해질 용액 및 아지리딘을 배합하는 단계를 포함하는 것을 특징으로 하는 대전방지코팅재의 제조방법이 제공된다.According to the present invention, (a) reacting polyol and diisocyanate in a molar ratio of 1: 2 to prepare a prepolymer, (b) neutralizing and ionizing functionalizable functional groups in the prepolymer, and (c) ionizing the prepolymer Mixing and reacting the chain extender and water to prepare a water-dispersed polyurethane having a solid content of 40-50% by weight, and (d) combining the prepared water-dispersed polyurethane with a polymer electrolyte solution and aziridine. There is provided a method for producing an antistatic coating material, characterized in that.

이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

일반적으로 기존의 수분산 폴리우레탄은 자기유화를 통하여 물에 분산된 형태가 유지되도록 디메틸올프로피온산과 같은 저분자량의 이온화가 가능한 디올을 사용하므로, 건조 후 형성된 폴리우레탄의 경질 부분에 이온기가 위치하여 대전방지에 기여하지 못한다.In general, the conventional water-dispersed polyurethane uses a diol capable of ionizing a low molecular weight such as dimethylol propionic acid to maintain a dispersed form in water through self-emulsification, so that the ionic group is located in the hard part of the polyurethane formed after drying It does not contribute to antistatic.

그러나 본 발명에서는 이온화가 가능한 작용기가 일정량 이상 도입된 폴리올을 수분산 폴리우레탄의 제조에 사용하여 코팅액의 건조후 도막을 형상하는 폴리우레탄의 연질부분(soft segment)에 이온기가 위치하여 건조후 도막이 대전방지 기능을 발휘하도록 하는 수분산 폴리우레탄을 사용한다.However, in the present invention, a polyol having a predetermined amount of ionizable functional groups introduced therein is used in the preparation of the water-dispersed polyurethane, and ion groups are positioned in the soft segment of the polyurethane to form a coating film after drying the coating solution. Use a water-dispersible polyurethane that provides a protective effect.

이러한 수분산 폴리우레탄의 제조를 위하여 먼저 이온화시킬 수 있는 작용기를 포함한 폴리올과 디이소시아네이트를 몰비로 1:2로 반응시켜 프리폴리머를 제조한다.In order to prepare such a water-dispersed polyurethane, a prepolymer is prepared by first reacting a polyol including a functional group that can be ionized with a diisocyanate in a molar ratio of 1: 2.

다음, 프리폴리머 중의 이온화될 수 있는 작용기를 중화시킨 후, 사슬 연장제를 첨가하고 고형분이 40 내지 50%가 되도록 물을 첨가한 다음 교반하에 반응시켜 수분산 폴리우레탄을 제조한다.Next, after neutralizing the ionizable functional groups in the prepolymer, a chain extender is added and water is added so that the solid content is 40 to 50%, followed by reaction under stirring to prepare a water-dispersed polyurethane.

이와같이 제조되는 수분산 폴리우레탄에 고분자 전해질 용액을 혼합하여 분산시킨다. 이때, 분산된 코팅 재료 중의 이온기들이 건조후에 더 이상 친수성을 가지지 않도록 가교구조를 도입하기 위해서 아지리딘을 첨가한다.The polymer electrolyte solution is mixed and dispersed in the water-dispersed polyurethane prepared in this way. At this time, aziridine is added to introduce a crosslinked structure such that the ionic groups in the dispersed coating material no longer have hydrophilicity after drying.

본 발명 대전방지코팅재에 있어서, 폴리우레탄과 고분자 전해질의 배합비율은 대전방지코팅재의 용도에 따라 다양하게 변화시킬 수 있는 것이므로 특별히 제한되지는 않으나, 고형분중량기준으로 폴리우레탄 100중량부당 고분자 전해질 5-30 중량부 정도가 적당하다. 또한 아지리딘의 첨가량은 도입된 이온화 작용기의 양에 의존한다.In the present antistatic coating material, the mixing ratio of the polyurethane and the polymer electrolyte is not particularly limited because it can be changed in various ways depending on the use of the antistatic coating material, polymer electrolyte per 100 parts by weight of polyurethane based on the solid content weight 5- 30 parts by weight is suitable. The amount of aziridine added also depends on the amount of ionization groups introduced.
