본 발명은 무용제형 에폭시 바닥재 피막조성물에 관한 것으로서, 더욱 상세하게는 작업환경 저하 및 대기 공해를 유발하는 용제의 함량이 거의 없는 고형분 용적비가 99% 이상인 무용제형 도료로서, 경화제의 적정한 선택으로 기계적 강도 개선효과를 얻고 있음은 물론 무용제형 도료와 칼라규사를 혼합하여 도장시에 규사 혼합물을 바탕면 위에 타설 및 미장하여 미끄러움을 방지하며, 분진을 방지하는 무용제형 에폭시 바닥재 피막조성물에 관한 것이다.The present invention relates to a solvent-free epoxy floor coating composition, and more particularly, to a solvent-free paint having a solid content ratio of 99% or more with little content of a solvent that causes a decrease in working environment and air pollution, and mechanical strength by appropriate selection of a curing agent. The present invention relates to a solvent-free epoxy flooring film composition which prevents slippage by pouring and plastering a silica sand mixture on a substrate surface by mixing a solvent-free paint and color silica sand as well as obtaining an improvement effect.
에폭시 수지는 적합한 경화제와 결합하여 여러 가지 용도에 널리 쓰일 수 있다. 에폭시 수지가 가지는 특성으로서 콘크리트 소지에의 우수한 부착력은 가장 주요한 장점이라 할 수 있으며, 콘크리트를 보호하기 위한 다른 타입의 도료에 비해 수축성이 적음은 물론 기계적, 화학적 내성이 커서 고기능성 도료에 사용하는데 적합하다. Epoxy resins can be widely used in various applications in combination with suitable curing agents. As the property of epoxy resin, excellent adhesion to concrete base is the most important advantage.It is suitable for use in high-performance paints due to its low shrinkage and mechanical and chemical resistance compared to other types of paints to protect concrete. Do.
현재 상품화가 되어 있는 에폭시 바닥재 시스템은 다음과 같이 크게 두 가지로 분류 되어질 수 있다: 용제형 하도 1회, 용제형 중도 2회, 용제형 상도 1회 로 마감하는 용제형 박막도장 시스템. 용제형 하도 1회, 무용제형 중도 1회, 용제형 상도 1회로 마감하는 무용제형 후막도장 시스템.Epoxy flooring systems that are currently commercialized can be broadly classified into two types: solvent type thin film coating systems that are finished with one solvent-based coating, two solvent-based intermediates, and one solvent-based coating. Solvent-free thick film coating system that finishes 1 time of solvent type under coating, 1 time of non-solvent type, and 1 time of solvent type top coat.
용제형(박막형) 타입의 경우, 로울러 작업성 및 레벨링 등이 양호한 도막을 얻기 위해서는 휘발성 용제를 다량 사용해야 하고, 이에 따라 대기 환경오염 및 작업자의 건강에의 유해성 및 미끄러움이 있다는 단점이 있다. 무용제형 타입으로서는 레끼 등을 이용하여 2000 ㎛ 이상을 도장하는 후막형(셀프레벨링 타입) 등이 있는데, 도막외관은 양호하나 최종 도막외관이 매끄러워 바퀴와의 마찰시 미끄러움과 소음이 심하다는 단점이 있다. In the case of the solvent type (thin film type), a large amount of volatile solvent must be used in order to obtain a good roller workability, leveling, etc., and thus, there are disadvantages of air pollution and hazards to workers' health and slippery. The solvent-free type includes a thick film type (self-leveling type) that coats 2000 μm or more using a squirrel, etc. The coating film has a good appearance, but the final coating appearance is smooth. There is this.
또한, 에폭시 바닥재를 현장적용시 도장도막이 브리틀(brittle)하여 쉽게 파괴되는 경향이 있으므로 도막의 경도가 있으면서 인장강도 및 압축강도가 양호하게 나타나는 도료가 절실히 필요하게 되었다.
In addition, since the coating film tends to be brittle and easily broken when the epoxy flooring material is applied in the field, a coating material having good tensile strength and compressive strength with the hardness of the coating film is urgently needed.
본 발명에서는 경화제에 적용된 아민류의 혼합 조성물 및 에폭시와 희석제의 적용은 그 혼합조성에 따라 경화가 너무 늦거라 빨라 현장적용에 문제가 될 뿐 아니라 기계적 강도에도 크게 영향을 미쳐 경화제의 적정한 혼합비를 얻는 것이 본 발명의 기술적 과제라 하겠다. 또한 미끄러움을 방지하기 위해 크기가 0.2 ∼ 1.0 mm 정도의 칼라규사를 적용 하였으며, 기계적 물성이 우수한 조성물을 얻기 위해 특정 경화제의 적용을 기반으로 하였다.In the present invention, the mixed composition of the amines applied to the curing agent and the application of the epoxy and the diluent are too late to cure depending on the mixing composition, which is not only a problem in the field application but also greatly affects the mechanical strength, thereby obtaining an appropriate mixing ratio of the curing agent. The technical problem of the present invention. In addition, to prevent slippage, color silica sand with a size of about 0.2 to 1.0 mm was applied, and based on the application of a specific curing agent to obtain a composition having excellent mechanical properties.
따라서, 본 발명은 작업환경을 악화 시키는 휘발성 용제의 함량이 거의 없는 고형분 용적비가 99% 이상인 무용제형으로서 기존 도장도막과는 달리 미끄러움이 없을 뿐만 아니라, 자동차의 운전시 바퀴의 마찰음이 거의 없으며, 기계적 강도가 우수한 무용제형 에폭시 바닥재의 피막조성물을 제공하는데 그 목적이 있다.
Therefore, the present invention is a non-solvent type having a solid content ratio of 99% or more, which has little content of a volatile solvent that worsens the working environment. It is an object of the present invention to provide a coating composition of a solvent-free epoxy flooring material having excellent mechanical strength.
본 발명은 에폭시수지, 비반응성 희석제, 경화제, 경화촉진제가 함유되어 있는 무용제형 에폭시 바닥재 도료조성물에 있어서, The present invention is a solvent-free epoxy floor coating composition containing an epoxy resin, a non-reactive diluent, a curing agent, a curing accelerator,
25 ℃에서 11,000 ∼ 14,000 cps의 점도를 가지며 에폭시 당량(EEW)이 184 ∼ 194인 에폭시수지 65 ∼ 73 중량%; 퍼퓨릴알코올 및 벤질알코올 중에서 선택된 1종 또는 2종 이상을 포함하는 비반응성 희석제 2 ∼ 10 중량%; 그리고 2급아민 1 몰에 대하여 3급아민이 0.25 ∼ 0.08 몰비를 이루고 있는 경화제 19 ∼ 31 중량%가 함유된 무용제형 에폭시 바닥재 도료조성물을 그 특징으로 한다.65 to 73% by weight of an epoxy resin having a viscosity of 11,000 to 14,000 cps at 25 ° C. and an epoxy equivalent (EEW) of 184 to 194; 2 to 10% by weight of a non-reactive diluent including one or two or more selected from perfuryl alcohol and benzyl alcohol; And a solvent-free epoxy floor coating composition containing 19 to 31% by weight of a curing agent having a tertiary amine of 0.25 to 0.08 molar ratio with respect to 1 mol of the secondary amine.
이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명이 사용하는 에폭시수지는 흔히 비스페놀-A라 불리는 디페닐을 에피클로로히드린과 반응시켜 생성되는 비스페놀 A의 디글리시딜에테르(DGEBA)로서, 평균 n값은 0.2 이하이고, 25 ℃에서 11,000 ∼ 14,000 cps의 점도를 가지며 에폭시 당량(EEW) 184 ∼ 194 범위의 것이다. 이러한 에폭시수지는 전제 도료조성물중에 65 ∼ 73 중량% 함유되는 바, 그 함량이 65 중량% 미만이면 도막의 강도가 불량하며, 73 중량%를 초과하면 점도가 높아 작업성이 떨어지게 된다. The epoxy resin used in the present invention is diglycidyl ether (DGEBA) of bisphenol A produced by reacting diphenyl, commonly referred to as bisphenol-A, with epichlorohydrin, and has an average n value of 0.2 or less, and at 25 ° C. It has a viscosity of 11,000 to 14,000 cps and an epoxy equivalent (EEW) in the range of 184 to 194. Such epoxy resin is contained 65-73% by weight in the total paint composition, if the content is less than 65% by weight of the coating film is poor, when the content exceeds 73% by weight, the workability is high due to the high viscosity.
비반응성 희석제는 기본적으로 수지의 고점도로 인한 작업의 제한성을 극복 할 수 있게 하기 위하여 도료에 적용되며, 높은 비휘발성으로 인하여 도막에 잔존, 경화된 도막의 일부분으로 형성하게 되는데 비반응성 희석제의 적용은 도막물성 저하(특히 경도)에 직접적인 원인이 되므로 적용에 제한을 받는다. 비반응성 희석제로는 퍼퓨릴알코올 및 벤질알코올 중에서 선택된 1종 또는 2종이 사용되며, 전제 도료조성물중에 2 ∼ 10 중량% 적용가능한데, 그 함량이 2 중량% 미만이면 도료의 점도가 높아 작업성이 불량해지는 경향을 보이고, 그 함량이 10 중량%를 초과하면 경도 등의 도막물성이 저하된다. Non-reactive diluents are basically applied to paints to overcome the limitations of work due to the high viscosity of the resin, and due to their high non-volatility, they are formed as part of the remaining and cured coatings in the coatings. Application is limited because it directly causes a decrease in coating properties (especially hardness). As the non-reactive diluent, one or two selected from perfuryl alcohol and benzyl alcohol are used, and it is applicable to 2 to 10% by weight in the whole paint composition. If the content is less than 2% by weight, the workability is high due to the high viscosity of the paint. If the content is more than 10% by weight, the coating film properties such as hardness are lowered.
경화제는 사용된 수지에 가장 적합한 것을 선택 사용하는 것이 주요하며, 경화제의 선택에 의해 최적의 물성을 나타낼 수 있다. 이에, 본 발명에서도 경화제의 종류 및 함량비를 적절히 조절하여 고강도의 에폭시 바닥재 도료를 제조할 수 있었다. 본 발명에 적용될 수 있는 경화제는 2급 아민과 3급아민의 혼합물으로서, 에폭시수지 및 비반응성 희석제의 종류에 따라 2급아민 : 3급아민을 1 : 0.25 ∼ 0.08 몰비의 범위로 유지시킴으로써 고경도의 기계적 물성이 우수한 도료조성물을 얻을 수 있다. 경화제로서 2급아민 : 3급아민의 혼합비가 1 : 0.25 몰비를 초과하면 3급아민에 의한 반응속도가 빨라 급속히 겔화되므로 작업성 및 도료안정성이 저하되고, 1 : 0.08 몰비 미만이면 반응속도가 느려 작업성 및 도료안정성은 향상되나 기계적 강도 및 경도가 저하되는 단점이 발생한다. 2급아민으로는 폴리옥시프로필렌디아민을 사용하며, 3급아민으로는 아미노에틸피페라진 또는 트리스디메틸아미노메틸페놀 중에서 사용할 수 있다. 이러한 경화제는 전제 도료조성물 중에 19 ∼ 31 중량% 함유되는 바, 그 함량이 31 중량%를 초과하면 미반응된 유 리아민(free amone)이 물과 반응함에 따라 도막의 내수성이 저하되고 도막 외관이 불량해질 수 있으며, 경화제의 함량이 19 중량% 미만 함유될 경우 에폭사이드기의 미반응으로 인해 내용제성 및 경도 등이 저하된다. It is important to select and use the hardening agent most suitable for the resin used, and the selection of the hardening agent may exhibit optimal physical properties. Thus, the present invention was also able to manufacture a high-strength epoxy floor coating material by appropriately adjusting the type and content ratio of the curing agent. The curing agent which can be applied to the present invention is a mixture of secondary amine and tertiary amine, and the hardness is maintained by maintaining the secondary amine: tertiary amine in the range of 1: 0.25 to 0.08 molar ratio depending on the type of epoxy resin and non-reactive diluent. A paint composition having excellent mechanical properties can be obtained. When the mixing ratio of the secondary amine to the tertiary amine as the curing agent exceeds 1: 0.25 molar ratio, the reaction rate by the tertiary amine is rapidly gelled, and thus the workability and paint stability decrease, and when the ratio is less than 1: 0.08 mole ratio, the reaction rate is slow. Workability and paint stability are improved, but mechanical strength and hardness are deteriorated. As the secondary amine, polyoxypropylene diamine may be used, and the tertiary amine may be used in aminoethylpiperazine or trisdimethylaminomethylphenol. The curing agent is contained 19 to 31% by weight in the total paint composition, if the content exceeds 31% by weight as the unreacted free amine (free amone) reacts with water, the water resistance of the coating film is reduced and the appearance of the coating film If the content of the hardener is less than 19% by weight, the solvent resistance and hardness are reduced due to the unreacted epoxide group.
그 밖에도 무용제형 에폭시 바닥재 피막조성물에 함유될 수 있는 통상의 첨가제가 필요에 따라 첨가될 수도 있다.In addition, conventional additives which may be contained in the solventless epoxy flooring coating composition may be added as necessary.
이상에서 설명한 본 발명의 도료조성물에 구경이 0.2 ∼ 1.0 mm 정도되는 칼라규사를 중량대비 1 ∼ 5 배 정도 혼합하여 도장하였을 때 미끄럼 현상이나 운전시 바퀴의 마찰음이 거의 없다.When the coating composition of the present invention described above is mixed with 1 to 5 times the weight of the color silica sand having a diameter of about 0.2 to 1.0 mm, the sliding phenomenon and the friction sound of the wheel during driving are almost no.
이와 같은 본 발명은 다음의 실시예에 의거하여 더욱 상세히 설명하겠는 바, 본 발명이 이에 한정되는 것은 아니다.
Such a present invention will be described in more detail based on the following examples, but the present invention is not limited thereto.
