Description
본 발명은 상온 경화형 폴리우레아 수지 및 이의 제조방법에 관한 것으로, 폴리우레아 수지의 경화시간을 늦춰 수작업 시공이 가능하도록 하는 상온 경화형 폴리우레아 수지 및 이의 제조방법에 관한 것이다. The present invention relates to a room temperature-curable polyurea resin and a method for manufacturing the same, which slows down the curing time of the polyurea resin to enable manual construction.
일반적으로 건축물의 옥상이나, 주차장, 지하실 등의 방수재 및 바닥재로 폴리우레탄이 주로 사용된다. 폴리우레탄(Polyurethane)은 알코올기와 아이소사이안기의 결합으로 만들어진 우레탄 결합으로 결합된 고분자 화합물로, 내열성, 내마모성, 내용제성, 내약품성이 뛰어나며, 탄성 섬유, 도료, 접착제 등으로 사용된다. 그러나 폴리우레탄(Polyurethane)은 도막의 내구성이 떨어져 외부 요인에 의해 도막의 찢김이나 파열이 비교적 쉽게 발생되는 문제가 발생할 수 있다. In general, polyurethane is mainly used as a waterproofing material and flooring material for building rooftops, parking lots, and basements. Polyurethane is a polymer compound made of urethane bonds made by combining alcohol groups and isocyanic groups. It has excellent heat resistance, abrasion resistance, solvent resistance, and chemical resistance, and is used in elastic fibers, paints, adhesives, etc. However, polyurethane has poor film durability, so external factors can cause tearing or rupture of the film relatively easily.
이러한 문제를 해결하기 위해 최근에는 폴리우레아(Polyurea)가 많이 사용되고 있는 추세이다. 폴리우레아(polyurea)는 윤활유, 기름 및 용매에 대한 적절한 내성을 지닌 것으로, 트럭의 베드 라이너, 균열 메꾸기 및 장식 디자인에 사용되며, 주로 에어리스 장비를 사용하여 이액형의 에어리스 스프레이 방식으로 사용된다. 그러나 폴리우레아는 경화시간이 빨라 소재와의 기밀성 및 접착력이 떨어지는 문제가 있으며, 스프레이 작업시 강한 압력에 의해 분진 발생이 많아 스모그 현상 등의 환경오염이 심각해지는 문제가 있다. 이에 현재 시장에서는 스프레이 작업을 제한하고 있는 실정이며, 환경문제가 발생하지 않는 대체물질과 작업을 요구하고 있어, 특허문헌 1, 2와 같이 친환경적이고, 수작업이 가능하도록 하는 폴리우레아 도료에 대한 개발이 진행되고 있으나, 아직 제품에 미치지는 못하고 있는 상황이다.To solve this problem, polyurea has been widely used recently. Polyurea has adequate resistance to lubricants, oils and solvents and is used in truck bed liners, crack filling and decorative designs, primarily as a two-component airless spray using airless equipment. However, polyurea has the problem of low airtightness and adhesion to materials due to its fast curing time, and the strong pressure during spraying generates a lot of dust, which causes serious environmental pollution such as smog. Accordingly, the current market is restricting spray work, and there is a demand for work with alternative materials that do not cause environmental problems, leading to the development of polyurea paints that are environmentally friendly and allow manual work, as shown in Patent Documents 1 and 2. Progress is being made, but it has not yet reached product level.
특허문헌 1은 수작업이 가능한 폴리우레아 도료에 관한 것으로, 주제부의 이소시아네이트기와 경화제부의 아민기의 몰비가 1:0.8~1로 배합하여 폴리우레아 도료를 제조함으로써, 가사시간이 길어 레기 또는 로라 등으로 도장 작업을 가능하도록 한 것이다.Patent Document 1 relates to a polyurea paint that can be applied by hand. By mixing the isocyanate group in the main part with the amine group in the hardener part at a molar ratio of 1:0.8 to 1, the polyurea paint is manufactured, so the pot life is long, so it can be painted with a resin or roller, etc. It made the work possible.
특허문헌 2는 친환경 하이브리드 폴리우레아수지계 도료조성물 및 그 시공 방법에 관한 것으로, 휘발성 유기화합물인 용제와 촉매를 포함하지 않으며, 과량의 필러를 사용하지 않아 친환경적인 폴리우레아수지계 도료조성물의 제조가 가능하도록 한 것이다.Patent Document 2 relates to an eco-friendly hybrid polyurea resin-based coating composition and its construction method. It does not contain solvents and catalysts that are volatile organic compounds, and does not use excessive fillers, enabling the production of an eco-friendly polyurea resin-based coating composition. It was done.

먼저, A액 제조단계이다. A액 제조단계는 1차 반응물 디아민 제조단계→ 기타 첨가물 혼합 및 포장 단계를 포함한다. 상세한 설명은 다음과 같다.First, the liquid A manufacturing stage. The liquid A preparation step includes the first reactant diamine preparation step → other additive mixing and packaging steps. The detailed explanation is as follows.
1차 반응물 디아민 제조단계이다.This is the first reactant diamine production step.
주제인 A액의 디아민은 디아민과 알데히드를 반응시켜 1차 반응물을 제조한다. 디아민을 반응기에 투입 후, 알데히드를 개량하여 드랍핑 탱크(dropping tank)에 투입한다. 이후, 반응 활성화를 위해 반응기 내부 온도를 서서히 승온하여 알데히드를 드랍핑(dropping) 시킨다. 이후, 반응이 종결되면 서서히 승온시켜 진공탈수를 통해 반응생성 수분을 제거하고, 수분이 완전히 제거되면 1차 반응물의 반응을 종결한다.The main reactant, diamine in solution A, is prepared as a primary reactant by reacting diamine with aldehyde. After diamine is added to the reactor, aldehyde is improved and added to the dropping tank. Afterwards, to activate the reaction, the temperature inside the reactor is gradually raised to drop the aldehyde. Afterwards, when the reaction is completed, the temperature is gradually raised and the moisture generated by the reaction is removed through vacuum dehydration. When the moisture is completely removed, the reaction of the first reactant is terminated.

In the present invention, diethyltoluenediamine, ethylenediamine, dimethylpiotoluenediamine, isophorone diamine, polyoxypropylene diamine, etc. are used, and any one or two or more types of these may be used.

또한, 이때, 필러는 10~30 중량부임이 바람직하며, 이는 필러가 30중량부보다 많이 첨가되면, 인장강도 및 연신율 등의 기능이 저하되는 문제가 발생할 수 있어, 이를 방지하기 위함이다.In addition, at this time, it is preferable that the filler is added in an amount of 10 to 30 parts by weight. This is to prevent the problem that functions such as tensile strength and elongation may decrease if the filler is added in more than 30 parts by weight.

다음, 경화제인 B액 제조단계이다. 상세한 설명은 다음과 같다.Next is the manufacturing step of liquid B, which is a hardener. The detailed explanation is as follows.
글리콜류 100중량부에 대하여 디이소사이네이트 100중량부를 반응기에 투입후, 반응 활성화를 위해 서서히 승온시켜 반응 후, 종결하여 B액을 제조하고, 제조된 B액을 포장한다.After adding 100 parts by weight of diisocyanate to the reactor for 100 parts by weight of glycols, the temperature is slowly raised to activate the reaction, and after the reaction is terminated, Liquid B is prepared, and the prepared Liquid B is packaged.
이때, B액은 말단기 디이소시아네이트를 제조하는 것으로, NCO기(이소시아네이트기) 함량은 14.5~15.5 중량%인 것이 바람직하다. 이는 주제 A액과 혼합 시, NCO기 함량이 너무 15.5 중량%보다 많으면, 경화가 되지 않고, 공기 중의 수분과 반응하므로, 물성이 떨어지는 문제가 발생할 수 있으며, NCO기 함량이 14.5 중량%보다 적으면 점도가 높아지는 문제가 발생하게 되어, 이를 방지하기 위함이다.At this time, solution B is for producing terminal diisocyanate, and the NCO group (isocyanate group) content is preferably 14.5 to 15.5% by weight. When mixing with main liquid A, if the NCO group content is too much more than 15.5% by weight, it does not harden and reacts with moisture in the air, which may cause problems with poor physical properties. If the NCO group content is less than 14.5% by weight, the product may not harden. This is to prevent the problem of increased viscosity.
이때, 디이소시아네이트로서 TDI(Toluene diisocyanate), MDI(Methylene Diphenyl diisocyanate), IPDI(Isophorone diisocyanate), HDI(Hexamethylene diisocyanate), XMDI(Xylyene diiscocyanate) 등이 사용될 수 있으며, 이 중 어느 1종 또는 2종 이상이 사용될 수 있다.At this time, as diisocyanate, TDI (Toluene diisocyanate), MDI (Methylene Diphenyl diisocyanate), IPDI (Isophorone diisocyanate), HDI (Hexamethylene diisocyanate), This can be used.
또한, 이때, 글리콜류는 폴리옥시 플로필렌글리콜, 폴리테트라메틸렌에테르글리콜, 1.4부틸렌글리콜, 폴리에틸렌글리콜 등이 사용될 수 있으며, 이 중 어느 1종 또는 2종 이상이 사용될 수 있다.Also, at this time, the glycols may be polyoxy propylene glycol, polytetramethylene ether glycol, 1.4 butylene glycol, polyethylene glycol, etc., and any one or two or more of these may be used.
다음, 혼합 및 시공단계이다.Next is the mixing and construction stage.
시공 시, 상기의 단계에서 제조된 주제 A액 100중량부에 대하여, 경화제 B액 70 중량부를 믹서기로 균일하게 혼합하여, 시공표면에 균일하게 시공 마무리한다. During construction, 70 parts by weight of hardener liquid B are uniformly mixed with a mixer for 100 parts by weight of main liquid A prepared in the above step, and the construction is finished evenly on the construction surface.
이때, 주제 A액과 B액은 A액 100중량부에 B액 70중량부를 혼합하는 것이 가장 바람직하며, 이는 아민 당량과 NCO 당량이 1:1인 것이 가장 바람직하며, 이에 해당하는 것이 주제 A액 100중량부, B액 70중량부 이기 때문이다. At this time, it is most preferable to mix main solution A and solution B with 100 parts by weight of solution A and 70 parts by weight of solution B. It is most preferable that the amine equivalent and NCO equivalent are 1:1, which corresponds to main solution A. This is because it is 100 parts by weight and 70 parts by weight of liquid B.
이하, 아래에서는 본 발명의 하나의 구체적인 실시 예로, 상세한 설명은 다음과 같다. Hereinafter, a specific embodiment of the present invention will be described below, and a detailed description is as follows.
먼저, A액 제조단계로, 1차 반응물 디아민 제조단계이다.First, the preparation step for solution A is the preparation step for the first reactant, diamine.
이소포론디아민 53.97 중량%를 반응기에 투입한다. 여기에 이소부틸알데히드 46.03 중량%를 개량하여 드랍핑 탱크(dropping tank)에 투입한다. 다음, 반응기 내부 온도를 서서히 60℃까지 승온하여 이소부틸알데히드를 8시간에 걸쳐 드랍핑(dropping)한다. 이후, 반응 종결 후 서서히 승온시켜 100℃를 유지하며 진공탈수 시켜 반응생성 수분을 제거한다. 수분이 완전히 제거되면 1차 반응물의 반응을 종결한다. 53.97% by weight of isophorone diamine is added to the reactor. Here, 46.03% by weight of isobutyraldehyde is improved and added to the dropping tank. Next, the temperature inside the reactor is gradually raised to 60°C and isobutyraldehyde is dropped over 8 hours. After completion of the reaction, the temperature is gradually raised, maintained at 100°C, and vacuum dehydration is performed to remove reaction-generated moisture. When moisture is completely removed, the reaction of the first reactant is completed.
이때, 분자의 구조식은 다음과 같이 형성된다.At this time, the structural formula of the molecule is formed as follows.
이때, 반응기 내에서는 이소포론디아민과 이소부틸알데히드의 반응에 의해 발열이 진행되므로, 65℃이상 온도 상승을 억제하면서 반응을 진행하는 것이 가장 바람직하다. 이는 이소부틸알데히드의 비점이 63~64℃이므로, 이소부틸알데히드의 비점 보다 너무 높은 온도로 상승되지 않도록 억제해줌으로써, 내부팽창이 발생하는 것을 제어하기 위함이다.At this time, since heat is generated by the reaction between isophoronediamine and isobutyraldehyde in the reactor, it is most desirable to proceed with the reaction while suppressing the temperature rise above 65°C. Since the boiling point of isobutyraldehyde is 63 to 64°C, this is to prevent internal expansion from occurring by preventing the temperature from rising to a temperature too high above the boiling point of isobutyraldehyde.
이때, 반응 종결 후, 반응 생성물인 수분을 제거해 주는 것이 바람직하다. 이는 수분이 존재할 경우 NCO와 반응하여 요소 결합 형성을 하므로, 이를 방지하기 위함이다.At this time, after completion of the reaction, it is desirable to remove the moisture that is the reaction product. This is to prevent the formation of urea bonds by reacting with NCO when moisture is present.
