천연물질로 이루어진 속성건조형 도료조성물{A paint composition}       Fast drying paint composition composed of natural materials {A paint composition}

본 발명은 천연물질로 이루어진 속성건조형 도료조성물에 관한 것으로서, 보다 상세하게는 천연물질로 이루어져서 인체에 무해할 뿐만 아니라 건조가 빨라 공기가 단축되는 등 사용성이 우수한 천연물질로 이루어진 속성건조형 도료조성물에 관한 것이다.The present invention relates to a fast drying paint composition made of a natural material, and more particularly, made of a natural material, not only harmless to the human body, but also fast drying to shorten the air, which is excellent in usability. It is about.

일반적으로 도료는 합성수지에 유기용제, 안료 및 기타 첨가제를 혼합하여 이루어진다. 이러한 도료는 유기용제가 휘발되면서 도료가 건조되어 도막이 형성되는데, 유기용제가 휘발되면서 인체에 유해한 휘발성 유기화합물이 발생된다. 휘발성 유기화합물은 비염, 아토피성피부염, 두드러기, 천식, 두통, 기관지염 등 각종 질병을 유발시키는 원인이 된다. 따라서 이러한 휘발성 유기화합물에 대한 피해를 줄이기 위해 휘발성 유기화합물을 발생시키는 제품에 대한 규제가 이루어지고 있다. Paints are generally made by mixing organic solvents, pigments and other additives with synthetic resins. The paint is dried and the paint is formed as the organic solvent is volatilized, the volatile organic compound harmful to the human body is generated as the organic solvent is volatilized. Volatile organic compounds cause rhinitis, atopic dermatitis, urticaria, asthma, headaches, bronchitis and other diseases. Therefore, in order to reduce the damage to these volatile organic compounds, regulations on products generating volatile organic compounds are being made.

한편, 친환경적인 제품으로 천연물질로 이루어진 도료조성물이 제안되고 있 다. 천연물질로 이루어진 도료조성물은 로진과 알코올이 에스테르화반응을 하여 얻어진 로진에스테르에 천연용제 및 안료 등을 혼합하여 제조된다. 그런데 이러한 천연물질로 된 도료조성물은 화학도료에 비해 휘발성 유기화합물이 발생되지 않는다는 장점이 있기는 하나, 건조되는데 장시간이 소요되는 단점이 있다. On the other hand, paint compositions made of natural materials have been proposed as eco-friendly products. A paint composition made of a natural material is prepared by mixing a natural solvent, a pigment and the like with a rosin ester obtained by esterification of rosin and alcohol. However, the paint composition made of such a natural material has the advantage that volatile organic compounds are not generated compared to chemical paints, but has a disadvantage in that it takes a long time to dry.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 인체에 무해할 뿐만 아니라 비교적 단시간에 속성건조되므로 사용성이 우수한 천연물질로 이루어진 속성건조형 도료조성물을 제공하는 것이다.
The present invention has been made to solve the above problems, and an object of the present invention is to provide a fast drying coating composition made of natural materials excellent in usability because it is quick to dry in a relatively short time.

본 발명에 따르면, 불포화지방산을 포함하는 오일과 로진에스테르가 반응하여 얻어진 수지성분과, 천연용제와, 천연안료와, 1,10-페난트로린을 포함하여 이루어지는 것을 특징으로 하는 천연물질로 이루어진 속성건조형 도료조성물이 제공된다. According to the present invention, a property consisting of a natural substance comprising a resin component obtained by reacting an oil containing an unsaturated fatty acid with a rosin ester, a natural solvent, a natural pigment, and 1,10-phenanthroline A dry paint composition is provided.

본 발명의 다른 특징에 따르면, 상기 1,10-페난트로린은 0.05~0.1중량%로 포함된 것을 특징으로 하는 천연물질로 이루어진 속성건조형 도료조성물이 제공된다. According to another feature of the present invention, the 1,10-phenanthrol is provided with a fast drying coating composition consisting of natural materials, characterized in that contained in 0.05 to 0.1% by weight.

이하, 본 발명을 구체적으로 설명하면 다음과 같다. 본 발명은 로진에스테르 와 오일이 반응하여 생성된 수지성분과, 천연용제와, 천연안료 및 1,10-페난트로린을 포함하여 이루어지는 도료조성물이다. Hereinafter, the present invention will be described in detail. The present invention is a paint composition comprising a resin component produced by the reaction of a rosin ester and an oil, a natural solvent, a natural pigment, and 1,10-phenanthrol.

상기 수지성분은 로진 또는 그 유도체와 알코올이 반응하여 생성된 로진에스테르와, 불포화지방산을 포함하는 오일의 Diel-Alder반응의 생성물이다. 상기 로진에스테르는 로진 중에 함유되어 있는 아비에트산, 데하이드로 아비에트산 또는 변성 아비에트산의 카르복실기와, 알코올의 하이드록시기가 반응하여 형성된다.The resin component is a product of a Diel-Alder reaction of a rosin ester produced by reacting rosin or a derivative thereof with an alcohol and an oil containing an unsaturated fatty acid. The rosin ester is formed by reacting a carboxyl group of abietic acid, dehydro abietic acid or modified abietic acid contained in rosin with an alcohol hydroxy group.

로진은 아비에트산을 주성분으로 가지는데, 아비에트산은 색상이 진한 담황색이다. 따라서 이러한 바이에트산에 의해 생성된 로진에스테르도 진한 담황색을 가지기 때문에 로진에스테르로 제조된 도료를 원하는 색상으로 조색하기 위해 안료를 첨가하여도 첨가된 안료의 색상이 제대로 발현되지 않는다. 따라서 로진에스테르의 색상을 엷게 변화시킬 필요가 있다. 이를 위해서는 로진의 주성분인 아비에트산의 일부를 디하이드로 아비에트산 또는 테트라하이드로 아비에트산으로 전환시키는데, 로진을 환원수소의 촉매 하에서 가열하여 아비에트산을 디하이드로 아비에트산과 테트라하이드로 아비에트산으로 전환시키는 불균등화반응을 행한다. 이와 같이 하면 로진의 색상이 담황색에서 엷은 베이지색으로 변화된다. 본 발명에서도 바람직하게는 상기와 같이 처리되어 색상이 엷은 베이지색으로 변화된 로진이 사용된다. Rosin has abiotic acid as a main ingredient, which is dark pale yellow in color. Therefore, since the rosin ester produced by the bieutic acid also has a dark pale yellow, the color of the added pigment is not properly expressed even when the pigment is added to color the paint made of the rosin ester to a desired color. Therefore, it is necessary to change the color of rosin ester lightly. To this end, part of the rosin's main component, abietic acid, is converted to dihydroabieteic acid or tetrahydroabietic acid.The rosin is heated under a catalytic reduction of hydrogen to convert the abiate acid to dihydroabietic acid and tetrahydroabieic acid. The disproportionation reaction to convert to This changes the rosin's color from pale yellow to pale beige. Also in the present invention, rosin which is preferably treated as described above and changed in color to pale beige is used.

상기 로진과 에스테르반응을 하는 알코올은 다가 알코올로서, 트리에틸렌 글리콜, 디에틸렌 글리콜, 에틸렌 글리콜, 펜타에리트리톨, 글리세롤 등이 사용될 수 있으며, 특히 바람직하게는 천연물질인 글리세롤이 사용된다. The alcohol which reacts with the rosin is a polyhydric alcohol, and triethylene glycol, diethylene glycol, ethylene glycol, pentaerythritol, glycerol, and the like may be used. Particularly preferably, natural glycerol is used.

이와 같이 생성된 로진에스테르와 오일의 Diels-Alder반응에 의해 상기 수지성분이 생성된다. 상기 오일은 이중결합을 갖는 불포화지방산을 함유하는 오일로서, 특히 바람직하게는 공액이중결합(conjugated double bond)을 갖는 불포화지방산을 함유하는 오일이 사용된다. 그 예로는 올레산, 리놀렌산 또는 엘레오스테아르산 등을 다량 포함하는 아마인유, 대두유, 텅유, 및 톨유 등이 있다. 이러한 오일은 보일유(boiled oil)로 제조되어야만 로진에스테르와 반응하기 때문에 전술한 오일들은 보일유로 가공되어 사용된다. The resin component is produced by the Diels-Alder reaction of the rosin ester and the oil thus produced. The oil is an oil containing an unsaturated fatty acid having a double bond, and particularly preferably an oil containing an unsaturated fatty acid having a conjugated double bond is used. Examples include linseed oil, soybean oil, tung oil, and tall oil containing a large amount of oleic acid, linolenic acid or eleostearic acid. Since these oils must be made of boiled oil to react with rosin esters, the above-mentioned oils are processed and used as boil oil.

상기와 같은 수지성분을 제조하는 과정에서 사용되는 로진에스테르의 양이 많아질수록 도료의 재도장성이 저하되며, 반대로 로진에스테르의 양이 적어질수록 건조가 늦어지는 단점이 있다. 그리고 사용되는 오일의 양이 많아질수록 건조가 늦어지고 점도가 저하되며, 오일의 양이 적어질수록 점도가 높아져서 점도조절을 위해 용제가 상대적으로 많은 양이 사용되어야 한다. 따라서 본 발명에서는 로진에스테르와 오일의 사용량은 수지성분 전체 중량에 대해 각각 30~50중량%, 50~70중량% 정도로 조절된다. As the amount of the rosin ester used in the process of preparing the resin component increases, the recoating property of the paint is lowered. On the contrary, as the amount of the rosin ester is decreased, the drying is delayed. As the amount of oil used increases, the drying delays and the viscosity decreases. As the amount of oil decreases, the viscosity increases, so that a relatively large amount of solvent must be used for viscosity control. Therefore, in the present invention, the amount of rosin ester and oil is adjusted to about 30 to 50% by weight and 50 to 70% by weight relative to the total weight of the resin component.

이와 같이 로진에스테르와 오일의 Diel-Alder반응에 의해 합성된 수지성분은고점도의 반고형 상태이므로, 천연용제에 의해 도장가능한 점도로 조절된다. 천연용제로는 오렌지, 라임, 박하, 소나무 등의 정제유에 다량 존재하는 리모넨 또는 피넨과 같은 테르펜류가 사용된다. Thus, the resin component synthesized by the Diel-Alder reaction of the rosin ester and the oil is a semi-solid state of high viscosity, and thus is adjusted to a paintable viscosity by a natural solvent. As a natural solvent, terpenes such as limonene or pinene, which are present in large amounts in refined oils such as oranges, limes, mints and pines, are used.

그리고 상기 천연안료는 체질안료와 색상안료로 구분되는데, 체질안료로는 운모, 탈크 등이 사용되며, 색상안료로는 백색인 경우에는 이산화티탄, 황색은 사 화철, 녹색은 크롬산화물, 파란색은 코발트 등이 사용된다. In addition, the natural pigments are divided into sieving pigments and color pigments, mica, talc, etc. are used as a sieving pigment, and when the color pigments are white, titanium dioxide, yellow is iron tetrachloride, green is chromium oxide, and blue is cobalt. Etc. are used.

한편, 상기 1,10-페난트로린(1,10-phenanthroline)은 도료조성물의 속성건조를 위해 혼합된다. 1,10-페난트로린이 많이 혼합될수록 도료조성물의 건조시간은 단축되나, 도료조성물이 황변되어 첨가된 안료의 색상이 제대로 발현되지 못하는 단점이 있다. 실험에 의하면, 1,10-페난트로린이 0.05중량% 보다 적게 혼합되는 경우에는 1,10-페난트로린에 의한 건조속도가 빨라지는 효과를 기대하기 곤란하였으며, 1,10-페난트로린이 0.1중량% 보다 많이 혼합되는 경우에는 도료조성물이 황변되었는데, 1,10-페난트로린의 혼합량이 증가할수록 황변정도가 심해졌다. 따라서 본 발명에서는 1,10-페난트로린의 혼합량은 도료조성물의 중량에 대해 대략 0.05~0.1중량%로 제한된다.On the other hand, the 1,10-phenanthroline (1,10-phenanthroline) is mixed for the rapid drying of the paint composition. The more the 1,10-phenanthrol is mixed, the shorter the drying time of the paint composition. However, the paint composition is yellowed, so that the color of the added pigment may not be properly expressed. According to the experiment, when 1,10-phenanthrol was mixed less than 0.05% by weight, it was difficult to expect the effect of increasing the drying rate by 1,10-phenanthrol and 0.1 weight of 1,10-phenanthrol. When more than% was mixed, the paint composition yellowed, and as the amount of 1,10-phenanthrol was increased, the degree of yellowing increased. Therefore, in the present invention, the mixing amount of 1,10-phenanthrol is limited to about 0.05 to 0.1% by weight based on the weight of the paint composition.

이와 같은 본 발명은 다음과 같은 방법으로 제조된다. Such a present invention is manufactured by the following method.

먼저, 로진과 알코올을 혼합하여 로진에스테르를 합성한 다음, 이 로진에스테르에 기 제조된 보일유를 혼합하여 수지성분을 제조한다. 그리고 이 수지성분에 천연안료와, 천연연용제를 혼합하는데, 이때 분산제나 습윤제 등이 추가로 첨가될 수도 있다. 그리고 1,10-페난트로린을 첨가하는데, 이 1,10-페난트로린은 사용 직전에 첨가하는 것이 바람직하다. First, rosin and alcohol are mixed to synthesize rosin ester, and then, the pre-prepared voile oil is mixed with the rosin ester to prepare a resin component. And a natural pigment and a natural softening agent are mixed with this resin component, At this time, a dispersing agent, a humectant, etc. may be further added. And 1,10-phenanthrol is added, which is preferably added immediately before use.

이상과 같이 제조되는 본 발명은 천연성분들로 이루어지므로 인체에 유해한 휘발성 유기물질이 발생되지 않는 등 인체에 무해하고 환견친화적일 뿐만 아니라 종래의 제품들에 비해 건조시간이 상당히 단축된다. The present invention manufactured as described above is made of natural ingredients, so that it is not harmful to the human body, such as no volatile organic substances harmful to the human body, and the drying time is considerably shorter than conventional products.

이상에서와 같이 본 발명에 의하면, 인체에 무해할 뿐만 아니라 비교적 단시간에 속성건조되므로 공기가 단축되어 공사비용이 절감되고, 이에 따라 경제성도 우수한 새로운 천연물질로 이루어진 속성건조형 도료조성물이 제공된다.
As described above, according to the present invention, it is not only harmless to the human body, but also rapidly drying in a relatively short time, thereby reducing the construction cost by reducing the air, thereby providing a fast drying coating composition composed of new natural materials having excellent economic efficiency.
