Description

열경화성 도막 박리용 조성물 {COMPOSITION FOR REMOVING PAINT FILM ON PLASTIC RESIN}TECHNICAL FIELD [0001] The present invention relates to a composition for peeling a thermosetting coating film,

본 발명은 열경화성 도막 박리용 조성물에 관한 것으로, 더욱 상세하게는 열경화성 고분자로 이루어진 도막의 제거 효율이 우수하며, 도막이 제거된 재료를 재활용할 수 있도록 하여 환경친화적인 효과를 나타내는 열경화성 도막박리용 조성물에 관한 것이다.
The present invention relates to a thermosetting coating film peeling composition, and more particularly, to a composition for peeling a thermosetting coating film exhibiting an environmentally friendly effect by allowing a coating film made of a thermosetting polymer to be efficiently removed, .

본 발명은 열경화성 도막박리용 조성물에 관한 것으로, 더욱 상세하게는 열경화성 고분자로 이루어진 도막의 제거 효율이 우수하며, 도막이 제거된 재료를 재활용할 수 있도록 하여 환경친화적인 효과를 나타내는 열경화성 도막박리용 조성물에 관한 것이다.The present invention relates to a thermosetting coating film peeling composition, and more particularly, to a composition for peeling a thermosetting coating film exhibiting an environmentally friendly effect by allowing a coating film made of a thermosetting polymer to be efficiently removed, .

일반적으로, 자동차, 가전제품, 일용 잡화 및 기타분야에 사용되는 각종 부품 중 상당량이 플라스틱 수지의 표면에 도장을 한 형태로 사용되고 있다. 그리고, 이들 플라스틱 수지의 도장에 사용되는 도료는 도장특성과 피착재인 플라스틱 수지와의 접착성 때문에 대부분 열경화성 도료로 사용되고 있어, 재료로 사용된 열가소성 플라스틱 수지를 재활용하기 위해서는 이 도막을 제거하지 않으면 단순 용융가공법으로는 재활용이 거의 불가능하게 된다.Generally, a large amount of various parts used in automobiles, household appliances, daily necessities and other fields are coated on the surface of plastic resin. The coating material used for coating these plastic resins is mostly used as a thermosetting coating material due to the coating property and the adhesion with the plastic resin which is an adhered material. In order to recycle the thermoplastic resin used as the material, Recycling is almost impossible with the processing method.

따라서, 이러한 문제점을 극복하기 위해서 다양한 방법이 시도되고 있는데, 주로 도막을 효율적으로 박리하는 방법이 이용되고 있다.Accordingly, in order to overcome such problems, various methods have been tried, and a method of effectively peeling the coating film is mainly used.

도막의 박리기술은 크게 두 가지로 나누어지는데, 물리적 방법과 화학적 방법으로 대별된다.The separation technique of coating film is roughly classified into physical and chemical methods.

물리적 방법은 도막에 물리적 힘을 가하여 도막을 분리시키는 것으로 샌드페이퍼 등으로 긁어내는 방법 등이 있으나 제거효율 및 경제성 등의 이유로 산업화에 많은 어려움이 있다.The physical method is to separate the film by applying physical force to the film and to scrape it with sand paper etc. However, it has many difficulties in industrialization because of the removal efficiency and economical efficiency.

또한, 화학적 방법에 의한 도막박리는 그 이론적 타당성으로 인해 지금까지 다양한 연구가 진행되어 오고 있는데 그 중 몇 가지 중요한 결과들은 다음과 같다. 즉, 염소계 용제(일본특공소 제 51-34238호 등), 유기물질(일본특개소 제 50-109925호 등) 및 무기물질을 주성분으로 하는 박리액제를 사용하는 방법(일본특개소 제 50-109925호 등)이 공개되었는데, 이들 방법들은 제거하고자 하는 도막의 종류와 두께에 따라 도막의 박리가 불완전하기 때문에 실용화가 어려운 문제점이 있다.In addition, due to its theoretical validity, various researches have been carried out so far. Some important results are as follows. That is, a method of using a chlorine-based solvent (Japanese Patent Laid-open Publication No. 51-34238), an organic material (Japanese Patent Laid-open No. 50-109925, etc.) and a release liquid containing an inorganic substance as a main component (Japanese Patent Laid- These methods have problems in that they are difficult to be practically used because the peeling of the coating film is incomplete depending on the kind and thickness of the coating film to be removed.

또 다른 방법으로는 도장된 플라스틱 성형품을 일정한 크기로 분쇄한 후 이 파쇄물을 스크류식 압출기에 공급하여 물, 알칼리수용액 또는 알코올을 공급하면서 용융 혼련시켜 도막의 분해가스와 기화된 물을 배기시켜 재생 플라스틱을 회수하는 방법(일본특개평 제 6-23748호)이 있다. 그러나, 이 방법도 여전히 재생수지에 알칼리 성분이 잔존하여 재생수지의 물성을 저하시키는 단점이 있으며, 또한 이를 감안하여 알칼리 사용량을 감소시키면 도막의 박리효과가 저하되는 문제점이 있었다.
Another method is to pulverize the painted plastic molded article to a predetermined size and then supply the pulverized product to a screw extruder to melt and knead it while supplying water, an aqueous alkali solution or alcohol to exhaust the decomposed gas of the film and the vaporized water, (Japanese Patent Application Laid-Open No. 6-23748). However, this method still has a disadvantage in that the alkaline component remains in the recycled resin, thereby deteriorating the physical properties of the recycled resin, and in view of this, there is a problem that if the amount of alkali used is reduced, the peeling effect of the coated film is deteriorated.

본 발명의 목적은 플라스틱 재료에 도포된 열경화성 도막의 제거효율이 우수한 열경화성 도막박리용 조성물을 제공하는 것이다.An object of the present invention is to provide a thermosetting coating film peeling composition which is excellent in the removal efficiency of a thermosetting coating film applied to a plastic material.

본 발명의 다른 목적은 플라스틱 재료에 도포된 도막을 박리할 때 사용되는 양이 적고, 짧은 반응시간과 낮은 반응온도를 나타내어 경제성 및 안정성 등이 우수한 열경화성 도막박리용 조성물을 제공하는 것이다.

Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

본 발명에 따른 열경화성 도막박리용 조성물은 수산화칼륨, 알코올 혼합물 및 유기용제로 이루어지며, 수산화칼륨 100 중량부, 알코올 혼합물 60 내지 80 중량부 및 유기용제 15 내지 25 중량부로 이루어지는 것이 바람직하다.
The composition for peeling a thermosetting coating film according to the present invention is composed of potassium hydroxide, an alcohol mixture and an organic solvent, and is preferably composed of 100 parts by weight of potassium hydroxide, 60 to 80 parts by weight of an alcohol mixture and 15 to 25 parts by weight of an organic solvent.

전술한 수산화칼륨은 100 중량부가 사용되며, 알칼리 반응물로써의 역할과 본 발명에 따른 도막박리용 조성물의 박리효과를 향상시키는 역할을 하는데, 박리과정이 종래보다 낮은 온도인 40 내지 45℃의 온도범위 내에서도 진행될 수 있도록 하며, 박리시간도 1 내지 3분을 나타내어 박리공정의 효율성을 향상시키고 비용을 절감하는 역할을 한다.The above-mentioned potassium hydroxide is used in an amount of 100 parts by weight, and serves to improve the role of the alkali reactant and the peeling effect of the composition for peeling paint according to the present invention. The peeling process is performed in a temperature range of 40 to 45 ° C And the peeling time is 1 to 3 minutes, thereby improving the efficiency of the peeling process and reducing the cost.

수산화칼륨의 함량이 100 중량부에서 낮아질수록 박리효과가 저하되며, 박리과정이 고온에서 진행되어야 하고, 박리시간이 길어지게 된다.
As the content of potassium hydroxide is lowered from 100 parts by weight, the peeling effect is lowered, and the peeling process must proceed at a higher temperature, and the peeling time becomes longer.

전술한 알코올 혼합물은 60 내지 80 중량부가 함유되며, 디에틸렌글리콜 45 내지 55 중량부, 벤질알코올 15 내지 25 중량부로 이루어지는데, 박리과정이 통상적으로 상온보다 높은 온도에서 진행되기 때문에, 박리과정에서 전술한 벤질알코올과 같은 알코올 성분이 휘발되는 것을 차단하기 위해 디에틸렌글리콜을 첨가하여 이루어지는 것이 바람직하다.The above-mentioned alcohol mixture contains 60 to 80 parts by weight of diethylene glycol, 45 to 55 parts by weight of benzyl alcohol, and 15 to 25 parts by weight of benzyl alcohol. Since the peeling process usually proceeds at a temperature higher than room temperature, It is preferable that diethylene glycol is added in order to block the volatilization of an alcohol component such as a benzyl alcohol.

전술한 디에틸렌글리콜은 본 발명에 따른 열경화성 도막박리용 조성물에 혼합되면 막을 형성하여 알코올성분이 휘발되는 것을 억제하기 때문에 도막박리용 조성물의 박리효과를 지속시켜주는 역할을 한다.
When the above-mentioned diethylene glycol is mixed with the thermosetting coating film peeling composition according to the present invention, it forms a film and inhibits volatilization of the alcohol component, so that it plays a role of continuing the peeling effect of the film peeling composition.

전술한 유기용제는 15 내지 25 중량부가 함유되며, 본 발명에 따른 도막박리용 조성물이 열경화성 도막으로 침투되는 효율을 향상시키는 역할을 하는데, 유기용제의 함량이 15 중량부 미만이면 침투효율이 저하되며, 25 중량부를 초과하게 되면 열경화성 도막뿐만 아니라, 플라스틱 재료에도 침투되어 플라스틱 재료의 표면을 손상시키게 된다.The organic solvent is contained in an amount of 15 to 25 parts by weight and serves to improve the efficiency with which the composition for peeling paint according to the present invention penetrates into the thermosetting coating. If the content of the organic solvent is less than 15 parts by weight, And if it exceeds 25 parts by weight, it penetrates not only the thermosetting coating film but also the plastic material, thereby damaging the surface of the plastic material.

이때, 전술한 유기용제는 프로필렌글리콜페닐에테르, 부틸렌글리콜페닐에테르, 디에틸렌글리콜페닐에테르, 디프로필렌글리콜페닐에테르, N-메틸피롤리돈, N-에틸 피롤리돈, N-프로필 피롤리돈, N-하이드록시메틸 피롤리돈 및 N-하이드록시에틸 피롤리돈으로 이루어진 그룹으로부터 선택된 하나 이상으로 이루어지는 것이 바람직하다.
The organic solvent may be any one selected from the group consisting of propylene glycol phenyl ether, butylene glycol phenyl ether, diethylene glycol phenyl ether, dipropylene glycol phenyl ether, N-methylpyrrolidone, N-ethylpyrrolidone, , N-hydroxymethyl pyrrolidone, and N-hydroxyethyl pyrrolidone.

또한, 전술한 열경화성 도막 박리용 조성물에는 계면활성제가 더 첨가될 수도 있는데, 전술한 열경화성 도막박리용 조성물에 함유된 수산화칼륨 100 중량부 대비 0.1 내지 2 중량부가 첨가되는 것이 바람직하다.In addition, a surfactant may be further added to the composition for peeling the thermosetting film, and it is preferable that 0.1 to 2 parts by weight of the surfactant is added relative to 100 parts by weight of the potassium hydroxide contained in the thermosetting film peeling composition.

전술한 계면활성제는 본 발명에 따른 열경화성 도막 박리용 조성물의 용해도를 더욱 향상시키는 역할을 하는데, 특히, 미세한 요철 구조 등과 같이 복잡한 구조를 갖는 플라스틱재료에 도포된 도막의 경우는 미세하게 형성된 홈의 모서리에 형성된 도막이 쉽게 박리되지 않기 때문에, 미세한 홈이 형성된 플라스틱재료에 형성된 도막을 박리할 경우에는 계면활성제를 첨가하는 것이 바람직하다.In the case of a coating film applied to a plastic material having a complicated structure such as a fine uneven structure, etc., the surface of the finely formed groove It is preferable to add a surfactant when peeling off a coating film formed on a plastic material in which a fine groove is formed.

전술한 계면활성제는 음이온계 계면활성제 또는 비이온계 계면활성제로 이루어지는 것이 바람직한데, 계면활성제의 함량이 0.1 중량부 미만인 경우에는 계면활성의 효과가 미미하며, 2 중량부를 초과하게 되면 도막의 박리효과가 저하된다.When the content of the surfactant is less than 0.1 part by weight, the effect of the surfactant is insignificant. When the amount of the surfactant is more than 2 parts by weight, the peeling effect of the coating film .

이때, 전술한 음이온계 계면활성제는 폴리옥시에틸에테르, 폴리옥시프로필에테르, 폴리옥시에틸옥틸페닐에테르, 폴리옥시프로필옥틸페닐에테르, 폴리옥시에틸프로필에테르 및 폴리옥시에틸프로필옥틸페닐에테르로 이루어진 그룹으로부터 선택된 하나 이상으로 이루어지며, 전술한 음이온계 계면활성제는 알킬설페이트나트륨으로 이루어지는 것이 바람직하다.The anionic surfactant may be selected from the group consisting of polyoxyethyl ether, polyoxypropyl ether, polyoxyethyl octyl phenyl ether, polyoxypropyl octyl phenyl ether, polyoxyethyl propyl ether and polyoxyethyl propyl octyl phenyl ether And the above-mentioned anionic surfactant is preferably composed of sodium alkylsulfate.

또한, 전술한 계면활성제는 본 발명에 따른 열경화성 도막 박리용 조성물을 정제수에 희석시켜 사용할 경우에 정제수와 전술한 유기용제가 원활하게 혼합될 수 있는 역할을 한다.
In addition, when the composition for peeling the thermosetting coating film according to the present invention is diluted with purified water, the above-mentioned surfactant plays a role of mixing the purified water and the above-mentioned organic solvent smoothly.

본 발명에 따른 열경화성 도막 박리용 조성물을 정제수에 희석시켜 사용하는 경우는 박리대상이 되는 도막이 평면 등과 같이 단조롭게 형성되는 재료에 도포되었을 경우에 사용하는 것이 바람직하며, 정제수 외에 이온교환수지를 통해 여과된 순수나, 비저항이 15 내지 20 옴(Ω)을 나타내는 초순수를 사용하는 것이 더욱 바람직하다.When the composition for peeling the thermosetting coating film according to the present invention is diluted in purified water, it is preferably used when the coating film to be peeled is applied to a monotonously formed material such as a flat surface. In addition to purified water, It is more preferable to use pure water or ultrapure water having a resistivity of 15 to 20 ohms (?).

또한, 본 발명에 따른 열경화성 도막 박리용 조성물을 정제수 또는 순수 또는 초순수에 희석시켜 사용할 경우에 희석비율은 열경화성 도막 박리용 조성물 100 중량부에 정제수 300 내지 600 중량부를 혼합하여 사용하는 것이 바람직하다.When the composition for peeling the thermosetting coating film according to the present invention is diluted with purified water or pure water or ultrapure water, the dilution ratio is preferably 300 to 600 parts by weight of purified water mixed with 100 parts by weight of the thermosetting film peeling composition.

본 발명에 따른 열경화성 도막 박리용 조성물은 열경화성 도막의 박리 효율이 매우 높기 때문에, 전술한 희석과정을 통해 희석액의 형태로 적용하더라도 도포된 면이 고른 도막의 제거에는 우수한 박리 효율을 나타낸다.
Since the composition for peeling the thermosetting coating film according to the present invention has a very high peeling efficiency of the thermosetting coating film, even when applied in the form of a diluting solution through the dilution process described above, the applied surface exhibits excellent peeling efficiency in removing a uniform coating film.

따라서, 본 발명에 따른 열경화성 도막박리용 조성물은 플라스틱 재료에 도포된 열경화성 도막의 제거효율이 우수하며, 도막이 제거된 플라스틱 재료를 재활용할 수 있도록 하기 때문에 환경친화적이며, 정제수 등과 같은 물에 희석하여 사용이 가능하기 때문에 도막 제거에 사용되는 양이 적고, 박리시간이 빠르며, 낮은 반응온도를 나타내어 경제성 및 안정성 등이 우수하다.Therefore, the composition for peeling the thermosetting coating film according to the present invention is excellent in the removal efficiency of the thermosetting coating film applied to the plastic material, and is environmentally friendly, and is diluted with water such as purified water and used , The amount used for removing the coating film is small, the peeling time is fast, the reaction temperature is low, and the economic efficiency and stability are excellent.
