Description

소수성을 부여한 고속건조형 수성 에폭시 도료의 조성물{Water epoxy paint composition equipped hydrophobicity}The composition of the high speed dry type | mold epoxy resin which provided hydrophobicity {Water epoxy paint composition equipped hydrophobicity}

본 발명은 수성 에폭시 도료 조성물에 관한 것으로, 더욱 상세하게는 기존 수성 에폭시 도료의 단점인 약한 내수성과, 물을 포함한 채로 경화가 이루어짐으로써 초래되는 약한 내구성을 해소한 수성 에폭시 도료에 관한 것이다.The present invention relates to an aqueous epoxy paint composition, and more particularly, to an aqueous epoxy paint that solves the weak water resistance, which is a disadvantage of the existing aqueous epoxy paint, and the weak durability caused by curing with water.

본 발명은 수성 에폭시 도료에 관한 것이다. 일반적으로 도료는 신나, 케톤, 벤제, 톨루엔 등의 휘발성 용제로 희석한 후 사용하는 유성도료와 물로 희석하여 사용하는 수성도료로 나뉜다.The present invention relates to an aqueous epoxy paint. Generally, paints are divided into oil paints used after dilution with volatile solvents such as thinner, ketone, benzine, toluene, and water-based paints diluted with water.

유성도료는 그 희석제인 용제로부터 대량의 휘발성 유기화합물이 발생하고, 이러한 물질은 독성을 가지고 있고 환경오염물질로 작용하기 때문에 그 함량을 낮추거나 아예 함유되지 않도록 할 수 있다면 바람직하다. 이러한 관점에서 휘발성 유기화합물을 발생시키지 않는 도료로서 수성도료가 요구되고 권장되는 경향이 강해지는 상황이다. 수성도료를 사용할 경우 유기 용제를 사용하지 않으므로 경제적 이고, 유기 용제 대신 물을 희석제로 사용하므로 독성이 없고 환경을 오염시키지 않기 때문이다.Oil-based paints are desirable if a large amount of volatile organic compounds are generated from the diluent solvent, and these substances are toxic and act as environmental pollutants, so that their contents can be lowered or not contained at all. From this point of view, as a paint that does not generate volatile organic compounds, an aqueous paint is required and recommended. It is economical when water-based paints are not used because organic solvents are not used. Since water is used as a diluent instead of organic solvents, it is not toxic and does not pollute the environment.

한편 예로부터 널리 사용되어 온 에폭시 도료는 강력한 부착력과 도막의 높은 경도 외에 내수성, 내화학성, 내마모성 등이 우수한 이점을 가지고 있어서 건축, 재료 등 다방면의 분야에서 광범위하게 사용돼 왔다. 그런데 에폭시 도료의 경우에도 유성의 도료는 전술한 문제점을 갖기 때문에 수성 에폭시 도료를 사용하는 게 바람직하다.Meanwhile, epoxy paints, which have been widely used since ancient times, have excellent advantages such as water resistance, chemical resistance, and abrasion resistance in addition to strong adhesion and high hardness of coating films, and thus have been widely used in various fields such as construction and materials. However, even in the case of epoxy paints, oil-based paints have the above-mentioned problems, so it is preferable to use an aqueous epoxy paint.

에폭시 도료는 모든 물성이 균형이 잡히고 접착력과 내수성도 뛰어난 도료이지만, 이를 수성화한 수성 에폭시 도료는 그 모든 물성과 작업성이 본래의 유성도료에 미치지 못하고 있다.Epoxy paints have a good balance of physical properties and excellent adhesion and water resistance. However, water-based epoxy paints that have been water-based have all of their properties and workability falling short of the original oil paints.

그 이유는 크게 두 가지로 집약할 수 있다. 첫째는 수성 에폭시는 에폭시 수지를 수성화하기 위해서 수지 자체 또는 외부에 계면활성제(유화제)를 포함하는 것이 필수불가결한 조건인바, 이 계면활성제는 물에 대한 친화력이 큰 관계로 도료의 내수성을 저하시킬 수 있는 위험이 있는 것이다. 둘째로는 이러한 친수성인 계면활성제로 인하여 물을 도막 안에 붙잡아두려는 성질(보습성)이 강하게 나타남으로 물을 포함한 채로 경화가 이루어질 수밖에 없는 상황이 초래된다는 점이다.There are two main reasons for this. First, the aqueous epoxy is indispensable to include a surfactant (emulsifier) on the resin itself or the outside in order to make the epoxy resin aqueous, since the surfactant has a high affinity for water, which reduces the water resistance of the paint. There is a risk to it. Second, these hydrophilic surfactants tend to hold water in the coating film (moisturizing) strongly, resulting in a situation in which hardening occurs with water.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 물에 대한 친화력이 큰 계면활성제를 함유하는 수성 에폭시 도료에 소수성을 부여함으로써 전술한 문제점을 해결하는 데 있다.The present invention has been made to solve the above problems, and an object of the present invention is to solve the above problems by providing hydrophobicity to an aqueous epoxy paint containing a surfactant having a high affinity for water.

즉, 계면활성제의 존재로 인한 자가당착적이면서도 불가피하게 수반되는 문제를 해결하기 위하여, 소수성이 크면서도 동시에 에폭시 수지의 유화를 깨뜨리지 않도록 함으로써, 도료의 건조 시에는 빠른 속도로 물을 밀어내고 도료의 경화 후에는 친수성기를 억누르고 내수성이 뛰어난 도막을 이룰 수 있도록 하는 데 본 발명의 목적이 있다.In other words, in order to solve the problem of self-acquisition and inevitably accompanied by the presence of a surfactant, it has a high hydrophobicity and does not break the emulsification of the epoxy resin at the same time, it pushes water at a high speed when drying the paint and After curing, the object of the present invention is to suppress a hydrophilic group and to form a coating film having excellent water resistance.

위 목적은 발명자가 안출한 가소제를 포함시킴에 의하여 해결될 수 있다.The above object can be solved by including the plasticizer devised by the inventor.

즉 본 발명의 기본적인 특징은, 수성 에폭시의 내수성을 떨어뜨리는 가장 큰 원인인 도막에 남아 있는 물이 속히 도료 밖으로 빠져나갈 수 있도록 하여 도막 안에 잔류수분이 전혀 남아있지 않은 상태에서 경화가 이루어질 수 있도록 일정한 구조를 갖는 물질을 넣어 소수성을 준 데에 있다.That is, the basic feature of the present invention is that the water remaining in the coating film, which is the biggest cause of deteriorating the water resistance of the water-based epoxy, can be quickly discharged out of the paint so that the curing can be performed in a state where no residual moisture remains in the coating film. It is to give hydrophobicity by putting substance with structure.

상기한 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

에폭시 수지와 충진제, 안료, 첨가제로 이루어지는 주제 파트와 이와 결합을 이루는 아민계통으로 이루어지는 경화제 파트를 포함하는 이액형 수성 에폭시 도료 에 있어서,In a two-component aqueous epoxy paint comprising an epoxy resin, a main part composed of a filler, a pigment, and an additive, and a curing agent part composed of an amine system formed therein,

It is a composition of the aqueous epoxy paint which contained the plasticizer so that the ratio which occupies for a main part may be 3 to 6 weight%, It is characterized by the above-mentioned.

이때, 상기 조성물에는 실리콘 처리된 흄드시리카를 주제 파트에서 차지하는 비율이 1중량%가 되도록 추가로 포함시킬 수 있다.At this time, the composition may be further included so that the proportion of the silicon-treated fumed silica in the main part is 1% by weight.

또한, 흄드시리카 대신 나노입자의 카오린을 주제 파트에서 차지하는 비율이 14중량%가 되도록 포함시킬 수도 있다.In addition, instead of the fumed silica, kaolin of the nanoparticles may be included in the main part so that the proportion is 14% by weight.

다음으로 흄드시리카 또는 나노입자의 카오린에 더하여, NP-PEO 계통의 계면활성제를 주제 파트에서 차지하는 비율이 0.1중량%가 되도록 추가로 포함시킬 수도 있다.Next, in addition to the fumed silica or kaolin of the nanoparticles, the NP-PEO-based surfactant may be further included so that the proportion of the main part is 0.1 wt%.

상기와 같은 구성에 의해 수성 에폭시 도료에 소수성을 부여함으로써 건조 시에 물을 외부로 내보내는 속도를 빠르게 하고 경화 시에 도막 안에 수분이 남아있지 않게 하므로 친환경적인 장점을 그대로 보유하면서도 모든 물성에서 유성 에폭시 도료에 필적하는 수성 에폭시 도료가 만들어질 수 있다.By giving hydrophobicity to the water-based epoxy paint as described above, it speeds up the rate of exporting water to the outside during drying and does not leave moisture in the coating film during curing. An aqueous epoxy paint can be made comparable to that.

본 발명의 위와 같은 구성은, 이론에서 출발한 것이라기보다는 에폭시 수지 의 개발에 수십 년간 종사해온 본 발명의 발명자의 무수한 경험과 창의적 상상력이 보태짐으로써 안출된 것임을 밝혀둔다.The above configuration of the present invention, rather than starting from the theory, it is revealed that the countless experience and creative imagination of the inventor of the present invention who has been engaged in the development of epoxy resin for decades.

상기한 구성의 본 발명에 따르면, 친환경적인 장점을 가졌음에도 내수성과 내구성이 떨어지는 단점을 가지고 있었던 수성 에폭시 수지의 물성을 대폭 향상시킬 수 있다.According to the present invention having the above-described configuration, it is possible to significantly improve the physical properties of the water-based epoxy resin, which had the disadvantage of poor water resistance and durability even though it has the environmentally friendly advantages.

위와 같이 실시예 2, 3, 5의 결과가 우수함을 확인할 수 있다. As described above, it can be confirmed that the results of Examples 2, 3, and 5 are excellent.

즉, 실시예에서 볼 수 있는 바와 같이 에폭시 수지와 상용성이 있는 방향족 비반응성 탄화수소만을 사용했을 때보다, 상용성은 더 떨어지지만 더 강력한 소수성을 나타내는 물질(C5계 탄화수소, 파라핀왁스, 다가알콜의 지방산 에스텔 등)과 병용했을 때에 축수시간이 단축이 되며 내수성도 좋아지는 현상을 확인할 수 있다.That is, as can be seen in the examples, materials having lower compatibility but stronger hydrophobicity (such as C 5 -based hydrocarbons, paraffin waxes, and polyhydric alcohols) are used when using only aromatic non-reactive hydrocarbons compatible with epoxy resins. When used together with fatty acid esters), it is possible to confirm a phenomenon in which the water-retaining time is shortened and the water resistance is also improved.
