본 발명은 건물의 주방, 화장실, 욕실, 베란다, 세면장, 로비 등에 설치된 타일의 줄눈 보수제 조성물에 관한 것으로서, 더욱 상세히는 내마모성과 접착력이 우수하며 수작업이 가능한 무황변 폴리아스파틱 우레아 줄눈 조성제에 관한 것이다.The present invention relates to a joint repair composition for a tile installed in a kitchen, a bathroom, a bathroom, a veranda, a toilet, a lobby, and the like. More specifically, the present invention relates to a non-yellowing polyarpatic urea joint composition having excellent abrasion resistance and adhesion, .
건물의 바닥, 벽 등의 표면을 피복하는 타일은 청소가 용이하고, 인테리어의 효과가 있어서 건물의 주방, 화장실, 욕실, 베란다, 세면장, 로비 등의 마감재로서 많이 사용되고 있다. 그러나, 물을 많이 사용하는 욕실 또는 베란다, 외부와의 접촉이 많은 로비 등에 사용되는 타일은 각종 오염물질에도 내구성이 강하여 장기간의 경과에도 오염에 강하고 청소가 용이하지만 타일들 사이의 줄눈금 부분은 시멘트계 줄눈으로 시공시 물때가 끼고, 곰팡이와 세균 등에 의한 오염문제가 발생할 수 있으며, 이는 환경적으로 위생적이지 못하게 된다. 또한, 이러한 물때나 곰팡이 등은 쉽게 제거되지 않는다는 문제점이 있다.The tiles covering the surface of the building floor and wall are easy to clean and have an effect of the interior, and thus they are widely used as finish materials for kitchens, restrooms, bathrooms, verandas, restrooms and lobbies of buildings. However, tiles used in water-intensive bathrooms or verandas, and in lots of contact with the outside, are resistant to various pollutants and are resistant to contamination even after a long period of time. Cleaning is easy, however, When the joint is applied with water, it may cause contamination problem due to fungi and bacteria, which is not environmentally hygienic. In addition, such water marks and fungi are not easily removed.
줄눈용 보수제로 가장 많이 사용되는 백색 시멘트는 다공성 재료로서 오염물질 등에 의해 쉽게 침투되며, 침투 후 공극속의 오염물질은 거의 제거가 불가능하다. 이러한 오염에 대한 해결책으로 실리콘 등의 발수성분을 첨가하고, 항곰팡이제의 첨가를 이용하여 곰팡이나 물때발생을 줄인 공법이 제시되기도 하였지만, 이러한 실리콘이나 항곰팡이제의 첨가는 줄눈용 보수제와 타일 및 콘크리트의 접착력을 악화시키는 원인이 되기도 하며, 내구성에 악영향을 미친다. White cement, which is most commonly used as a joint repair agent, is a porous material that easily penetrates by contaminants, and it is almost impossible to remove contaminants in the pores after penetration. As a solution to this pollution, a method of adding water-repellent component such as silicone and antifungal agent to reduce the occurrence of fungus or watery was proposed, It may cause deterioration of the adhesive strength of the concrete and adversely affect the durability.
최근에는 백시멘트를 이용한 줄눈의 문제점을 극복하고자 에폭시 타입의 줄눈제가 많이 사용되고 있는 실정이다. In recent years, epoxy type joints have been widely used to overcome the problem of joints using white cement.
특허 제10-0934561는 수성 에폭시 시스템을 이용한 타일 줄눈용 보수제로서 타일 준눈제를 시공한 후 물기에 장시간 노출 될 경우 타일과의 접착력이 떨어지는 문제가 있으며, 겨울철에는 수성 제품이라 영화의 온도에서 시공이 되지 않으며, 경화시간이 길어 문제가 된다.Patent No. 10-0934561 is a repair agent for a tile joint using an aqueous epoxy system. When a tile is applied to a tile, the adhesive strength to the tile is low when exposed to water for a long time. In winter, And the curing time is long, which is a problem.
수성 에폭시의 단점을 극복하기 위해서 현재 무용제형 에폭시 줄눈 보수제가 많이 사용되고 있다. 하지만, 에폭시 경화물의 경우 햇빛 노출 등의 장시간 노출에 의한 황변현상을 방지하기 위하여 알리파틱 아민계 경화제를 사용함에도 불구하고 에폭시 구조의 근본적인 아로마틱 구조를 가지는 비스페놀을 배제할 수 없기에 장기적인 관점에서 황변의 문제를 많이 가지고 있다. 또한, 에폭시 줄눈 보수제 시공시 대기 중의 이산화탄소나 습기 등과 반응하여 에폭시 수지가 하얀색으로 변하는 브러쉬 현상이 발생하는 문제가 있다. 그리고, 겨울철 등의 추운 날씨에는 초기 경화 속도가 느려 내수백화성이 나빠지고, 완전경화가 늦어지는 이유로 겨울철에는 줄눈 보수제로서 에폭시 사용을 피하는 실정이다.In order to overcome the disadvantages of aqueous epoxy, a solventless epoxy joint repair agent is widely used. However, in the case of epoxy cured products, bisphenol having a fundamental aromatic structure of epoxy structure can not be excluded in spite of using an aliphatic amine-based curing agent to prevent yellowing due to prolonged exposure such as sunlight exposure. Therefore, . Further, there is a problem that when the epoxy joint repair agent is applied, the epoxy resin reacts with carbon dioxide or moisture in the atmosphere to cause a brush phenomenon in which the epoxy resin changes to white. In cold weather such as winter season, the initial curing speed is slow and hundreds of cracks are deteriorated. As a result, the epoxy resin is used as a joint repair agent in winter due to the delay of complete curing.
특허 제10-1242642는 에폭시 변성 하이브리드 폴리우레탄 프리폴리머 수지와 지환족 변성 아민을 사용하여 경화속도가 빠르고, 초기 내수성 및 내화학성이 우수한 줄눈 조성물에 관한 특허로서, 분자 내에 우레탄기와 에폭시기를 모두 포함하여 기계적 및 화학적 물성을 높였으며, 무황변이어서 변색이 없는 에폭시 줄눈제로서 소개가 되어있으나, 상기의 특허에 사용된 지환족 아민의 경우에 아로마틱 구조를 가지고 있는 비스페놀 F형 에폭시 수지를 지방족 아민과 부가 반응시킨 지환족 변성 아민을 사용하고 있기에 황변이 일어날 수밖에 없는 취약한 구조를 가지고 있다.Patent No. 10-1242642 discloses a joint composition having an epoxy-modified hybrid polyurethane prepolymer resin and an alicyclic modified amine and having a high curing speed and excellent initial water resistance and chemical resistance. The patent discloses a joint composition containing both urethane and epoxy groups in a molecule, And its chemical properties are improved, and it is introduced as an epoxy joint without a discoloration since it is non-yellowish. However, in case of the alicyclic amine used in the above patent, bisphenol F type epoxy resin having an aromatic structure is added with an aliphatic amine Which has a weak structure that yellowing can not occur due to the use of an alicyclic modified amine.
특허 출원 2012-0158492는 타일 줄눈용 보수재로서 에폭시의 황변현상 및 백화현상을 개선하기 위하여 폴리우레아를 이용한 공법을 제시한 특허로서, 폴리우레아의 경화제로 사용하는 일반적인 지방족 폴리아민, 변성 지방족 폴리아민 및 아로마틱 아민으로 이루어진 그룹으로부터 선택된 것을 사용하는 것을 언급하였으나, 일반적인 폴리우레아 시스템에서 사용되는 상기와 같은 아민은 주제부의 이소시아네이트와의 수 초 안에 경화되는 빠른 반응성으로 현장 작업시 스프레이 기기를 사용하여야 하는 문제점을 가지고 있어서, 일반적인 타일 줄눈 보수제 시공에 사용하기에는 무리가 있다. Patent application 2012-0158492 is a repairing material for tile joints. It is a patent that proposes a method using polyurea to improve the yellowing phenomenon and whitening phenomenon of epoxy. It is a common aliphatic polyamine, a modified aliphatic polyamine and an aromatic amine used as a hardener of polyurea However, the amine used in general polyurea systems has a problem in that it is required to use a spray device in the field work due to its rapid reactivity to harden in a few seconds with isocyanate in the main part , It is difficult to use it for general tile joint repairing construction.

Unlike conventional epoxies or polyureas, the polyaspartic urea joint compositions use aliphatic based materials in both the main part (A) and the hardener part (B), and yellowing is hardly generated, but the addition of an additional UV stabilizer It prevents discoloration and yellowing for a long time by use. The ultraviolet stabilizer or antioxidant is preferably used in an amount of 0.2 to 1.0% by weight based on the total weight of the curing agent (B). When the curing agent is used in an amount less than 0.2% by weight, the ultraviolet stabilizer or antioxidant hardly affects the weatherability of the polyaspartic urea When it exceeds 1.0% by weight, the weatherability of the polyaspartic urea joint coating film is not greatly changed, which is economically ineffective. For example, TINUVIN B7, TINUVIN 292, 2,6-di-t-butyl-4-methylphenol (BHT), ZIKA-UVS3, Irganox 1010 have.
상기 흐름조절제는 폴리아스파틱 우레아 줄눈제 조성물의 점도 및 흐름성을 조절하는데 사용된다. 상기 흐름조절제의 함량은 경화제부(B) 전제 중량의 0.1~4.0중량% 내에서 줄눈제 작업 시공성을 고려하여 선택하는 것이 바람직하며, 4.0중량%를 초과하게 되면 폴리아스파틱 우레아 줄눈제 도막이 소광 되어 광택이 줄어들 수 있다. 예를 들어, 상기 흐름조절제로는 Aerosil 200, HDK H-15(이상 상품명) 등이 사용 될 수 있다.The flow control agent is used to control the viscosity and flowability of the polyaspartic urea joint composition. The content of the flow control agent is preferably selected in consideration of the workability of the joint work within 0.1 to 4.0% by weight of the total weight of the curing agent part (B). When the amount exceeds 4.0% by weight, the polyaspartic urea joint coating agent is extinguished The gloss can be reduced. For example, Aerosil 200, HDK H-15 (trade name) or the like may be used as the flow control agent.

폴리아스파틱Polyaspic 우레아Urea 줄눈제Jointing agent 도막의 성능 평가 Evaluation of coating performance
하기의 표 2는 상기 표의 조성대로 제조한 폴리아스파틱 우레아 줄눈제 조성물의 물성을 평가한 결과를 나타낸 것이다. 비교예1은 현재 자사에서 판매하고 있는 일반적인 에폭시 줄눈제(HEC-500RH)를 사용하였고, 비교예2는 바닥코팅재로 사용하고 있는 폴리우레아 제품(HSC-D50PR)을 사용하였다.Table 2 below shows the results of evaluating the physical properties of the polyaspartic urea-based urethane composition prepared according to the composition of the above table. In Comparative Example 1, a common epoxy joint agent (HEC-500RH) sold by the company was used. In Comparative Example 2, a polyurea product (HSC-D50PR) used as a floor coating material was used.
주제부와 경화제부를 배합비에 맞추어 교반기로 300rpm, 1분간 혼합 교반 후 폴리에틸렌(PE) 판에 약 1mm의 두께로 도막을 만든 후 온도 25℃, 습도 60%의 항온항습기에서 7일간 양생하고 겔타임, 인장강도, 신장율, 접착강도, 경도 등을 측정하였다. 구체적으로, 만능인장시험기를 이용하여 KS F 4922 시험방법으로 인장강도와 신장율, KS L 1592 방법으로 접착강도를 측정하였고, Shore D 경도계를 이용하여 경도를 측정하였다. 내마모성은 ASTM D4060-10(H22 wheel, 9.8N road, 1000cycle)의 방법으로 도막의 감소된 중량을 측정하였다. 변색 안정성은 ASTM G154-12(UVA-340 Lamp, 4hr UV, 4hr Condensation, total 1000hr) 방법으로 1000시간 자외선에 노출한 후, 변색 및 황변 현상이 나타나는지 여부를 관찰하였다. 가사시간은 작업이 가능한 시간을 측정하였다.The mixture was stirred at 300 rpm for 1 minute with a stirrer to prepare a film having a thickness of about 1 mm on a polyethylene (PE) plate. The mixture was cured for 7 days in a constant temperature and humidity chamber at 25 ° C and a humidity of 60% Tensile strength, elongation, adhesive strength, hardness and the like were measured. Specifically, the tensile strength and elongation were measured by KS F 4922 test method using a universal tensile tester, and the bonding strength was measured by KS L 1592 method. Hardness was measured using a Shore D hardness meter. The abrasion resistance was measured by the method of ASTM D4060-10 (H22 wheel, 9.8 N road, 1000 cycle). The discoloration stability was evaluated by discoloration and yellowing after exposure to ultraviolet light for 1000 hours by ASTM G154-12 (UVA-340 Lamp, 4hr UV, 4hr Condensation, total 1000hr) method. The housework time measured the time available for the work.
실시예 1~5, 비교예 1~2의 결과를 통하여 알콕시변성이소시아네이트를 포함하는 폴리아스파틱 우레아 줄눈제 조성물의 접착강도, 인장강도 등이 기존의 에폭시 또는 일반적인 폴리우레아와 동등 이상의 우수한 물성을 가지는 것을 알 수 있었다. The results of Examples 1 to 5 and Comparative Examples 1 to 2 show that the adhesive strength and tensile strength of the polyaspartic urea-based urethane composition containing an alkoxy-modified isocyanate are superior to those of conventional epoxy or general polyurea .
신장율에 있어서도 에폭시 줄눈제 보다 적게는 3배에서 많게는 9배 이상의 향상된 결과를 얻을 수 있었는데, 이는 건물의 충격, 진동 또는 크랙에 의해 도막이 손상될 위험성을 내재하고 있는 에폭시 줄눈제 보다 더 높은 탄성으로 인하여 충격 및 진동에 의한 도막의 손상을 방지할 수 있어 내구성이 향상됨을 알 수 있었다. The elongation was also improved by 3 times to 9 times than that of epoxy joints because of the higher elasticity of the epoxy joints, which have the risk of damaging the coating due to impact, vibration or cracks in the building It is possible to prevent the damage of the coating film due to impact and vibration, thereby improving durability.
비교예 2의 일반적인 폴리우레아 시스템를 이용한 줄눈제의 경우에는 빠른 경화속도로 인하여 폴리우레아 전용 도장 기계를 사용하여야 하나, 본 발명의 폴리아스파틱 우레아 줄눈제의 경우에는 알리파틱 이소시아네이트와 아스파틱 아민의 느린 반응성으로 20분 이상의 가사시간으로 인하여 수작업이 가능하다는 것을 확인할 수 있었다.In case of the jointing agent using the general polyurea system of Comparative Example 2, it is necessary to use a paint machine exclusive for polyurea due to a fast curing speed. In the case of the polyaspartic urea joint agent of the present invention, It was confirmed that the reaction time was 20 minutes or longer and the manual operation was possible.
실시예 결과를 통하여 폴리아스파틱 우레아 줄눈제 조성물은 알리파틱 구조로 인하여 아로마틱 구조의 폴리우레아나 비스페놀 구조의 에폭시 보다 장기간의 자외선 노출에도 표면의 변색이나 황변이 일어나지 않는다는 것을 확인 하였다.From the results of the examples, it has been confirmed that the polyaspartic urea-based epoxy resin composition does not cause discoloration or yellowing of the surface even after long-term exposure to ultraviolet rays, due to the aliphatic structure, rather than the polyurea or bisphenol structure epoxy of the aromatic structure.
