Description
본 발명은 무취의 2액형 에폭시수지 조성물에 관한 것으로서, 냄새가 없어서 작업성이 우수하고 환경친화적인 새로운 조성의 무취의 2액형 에폭시수지 조성물에 관한 것이다. The present invention relates to an odorless two-component epoxy resin composition, and to a odorless two-component epoxy resin composition having a new composition having no odor and having excellent workability and being environmentally friendly.
에폭시수지 조성물은 경화시에 부피의 수축이 없고, 기계적, 화학적 내성이 큰 특징을 가지므로 코팅제, 접착제, 주형제 등 다양한 분야에 이용되고 있다. 특히, 에폭시수지 조성물은 우수한 접착강도를 가지므로 코팅제로서 널리 이용된다. Epoxy resin composition has no characteristics of shrinkage of volume during curing, and has a great mechanical and chemical resistance, and thus is used in various fields such as coating agents, adhesives, and molding agents. In particular, since the epoxy resin composition has excellent adhesive strength, it is widely used as a coating agent.
이러한 에폭시수지 조성물은 1액형과 2액형으로 구분되는데, 1액형은 건조속도가 빠른 장점이 있으나, 가열경화하여야 하는 단점이 있으며, 2액형 타입은 화학적 반응으로 경화되는 주제와 경화제로 이루어지는데, 사용시 주제와 경화제를 혼합하여 사용하여야 하는 번거로움이 있으나, 상온경화되는 장점을 가지며 1액형에 비해 상대적으로 접착성, 내약품성, 내식성, 내수성 등의 물성이 상대적으로 더 우수한 장점을 가진다.The epoxy resin composition is divided into one-component and two-component, one-component has the advantage of fast drying speed, but has the disadvantage of having to be heat-cured, two-component type consists of the subject and the curing agent that is cured by chemical reaction, when used Although it is cumbersome to use a mixture of a main agent and a curing agent, it has the advantage of being cured at room temperature and relatively superior properties of physical properties such as adhesion, chemical resistance, corrosion resistance, and water resistance compared to a one-component type.
한편, 이러한 2액형 에폭시수지 조성물은 사용 전에 주제와 경화제를 혼합하여 사용하는데, 주제와 경화제에는 도장작업을 효율적으로 하기 위해 유기용제가 포함된다.On the other hand, the two-component epoxy resin composition is used by mixing the main agent and the curing agent before use, the main agent and the curing agent contains an organic solvent in order to efficiently paint.
그러나 유기용제가 사용된 에폭시수지 조성물은 유기용제 특유의 냄새로 인해 작업환경이 취약해져서 작업효율이 저하되며, 경우에 따라 작업자가 두통이나 호흡곤란을 일으키는 등 작업자의 건강에도 좋지 않은 영향을 미칠 뿐만 아니라 유기용제에서 휘발되는 유해성분으로 인해 환경오염도 유발된다. However, the epoxy resin composition using the organic solvent has a weak working environment due to the smell of organic solvents, which lowers the working efficiency. In some cases, the worker has a bad effect on the worker's health, such as a headache or difficulty in breathing. In addition, environmental pollution is also caused by the volatile components in the organic solvent.
본 발명은 상기와 같은 점에 착안하여 제안된 것으로서, 유기용제가 아닌 희석제를 사용함으로써 냄새가 없어서 작업성이 우수하고 환경친화적인 새로운 조성의 무취의 2액형 에폭시수지조성물을 제공하는 것이다. The present invention has been proposed in view of the above, by using a diluent rather than an organic solvent to provide a odorless two-component epoxy resin composition of a new composition excellent in workability and environmentally friendly with no smell.
본 발명의 특징에 따르면, 비스페놀 A의 디글리시딜 에테르(Diglycidyl ether of bisphenol A) 50~65중량부, 1,6-비스(2,3-에폭시프로폭시)헥산(1,6- Bis(2,3-epoxypropoxy)hexane) 10~20중량부를 포함하는 주제; 및 n-아미노에틸피페라진(n-aminoethylpiperazine) 15~35중량부, 1,3 벤젠디메탄아민(1,3 Benzenedimethanamine) 20~25중량부, 변성 지방족 아민 3~10중량부, 벤질알코올(benzyl alcohol) 3~15중량부, 비스페놀 A의 디글리시딜 에테르(diglycidly ether of bisphenol A) 5~15중량부를 포함하는 경화제;를 포함하는 것을 특징으로 하는 무취의 2액형 에폭시수지 조성물이 제공된다. According to a feature of the present invention, 50 to 65 parts by weight of diglycidyl ether of bisphenol A, 1,6-bis (2,3-epoxypropoxy) hexane (1,6-Bis ( 2,3-epoxypropoxy) hexane) main subject including 10-20 parts by weight; And 15 to 35 parts by weight of n-aminoethylpiperazine (n-aminoethylpiperazine), 20 to 25 parts by weight of 1,3 benzenedimethanamine, 3 to 10 parts by weight of modified aliphatic amine, benzyl alcohol (benzyl Alcohol) 3 to 15 parts by weight, a curing agent comprising 5 to 15 parts by weight of diglycidly ether of bisphenol A; Provides an odorless two-component epoxy resin composition comprising a.
본 발명의 다른 특징에 따르면, 상기 주제와 경화제는 1: 0.25~0.4 중량비로 혼합된다. According to another feature of the invention, the subject and the hardener are mixed in a weight ratio of 1: 0.25 to 0.4.
본 발명의 또 다른 특징에 따르면, 상기 주제에는 충진제가 더 함유되며, 상기 충진제는 삼산화안티몬, 흄드 실리카(Fumed silica)를 포함한다. According to another feature of the invention, the subject further contains a filler, the filler comprises antimony trioxide, fumed silica (Fumed silica).
이상과 같은 조성을 가지는 본 발명은 유기용제를 사용하지 않고 희석제를 사용함으로써 종래 유기용제의 사용에 따른 냄새가 발생되지 않는다. In the present invention having the composition as described above, by using a diluent without using an organic solvent, an odor caused by the use of a conventional organic solvent is not generated.
따라서 냄새가 거의 없어서 작업환경이 개선되며, 이에 따라 작업효율이 향상되며, 인체에도 무해하고 휘발성 유해물질에 의한 환경오염도 유발되지 않으므로 환경친화적이다. 뿐만아니라, 본 발명은 기계적, 화학성 특성도 우수하며 도장작업에 요구되는 적절한 가사시간이 확보되는 장점도 가진다. Therefore, there is almost no odor, the working environment is improved, and thus the working efficiency is improved, which is harmless to the human body and does not cause environmental pollution by volatile harmful substances. In addition, the present invention is excellent in mechanical and chemical properties and has the advantage of ensuring the appropriate pot life required for painting work.
이하에서, 본 발명을 좀 더 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명은 주제와 경화제로 구성되는데, 각각의 구체적인 조성은 다음과 같다. The present invention consists of a subject and a curing agent, each specific composition is as follows.
[주제] [subject]
ⅰ) 비스페놀 A의 디글리시딜 에테르(Diglycidyl ether of bisphenol A)Iii) Diglycidyl ether of bisphenol A
: 비스페놀 A의 디글리시딜 에테르는 이 기술분야에서 알려 있는 에폭시 수지성분이다, 바람직하게는 비스페놀 A디글리시딜 에테르는 50~65중량부 사용된다. The diglycidyl ether of bisphenol A is an epoxy resin component known in the art. Preferably, 50 to 65 parts by weight of bisphenol A diglycidyl ether is used.
ⅱ) 1,6-비스(2,3-에폭시프로폭시)헥산(1,6- Bis(2,3-epoxypropoxy)hexane)Ii) 1,6-bis (2,3-epoxypropoxy) hexane (1,6-Bis (2,3-epoxypropoxy) hexane)
: 1,6-비스(2,3-에폭시프로폭시)헥산은 반응성 희석제로서, 경화제와의 경화반응에 참여하여 수지조성물의 점도를 낮추고 유연성을 부여한다. : 1,6-bis (2,3-epoxypropoxy) hexane is a reactive diluent, which participates in the curing reaction with the curing agent to lower the viscosity of the resin composition and impart flexibility.
바람직하게는 1,6-비스(2,3-에폭시프로폭시)헥산은 10~20중량부 사용된다. 1,6-비스(2,3-에폭시프로폭시)헥산이 10중량부 미만으로 사용되면 1,6-비스(2,3-에폭시프로폭시)헥산에 의한 효과가 미미하고, 20중량부를 초과하여 사용되면 수지조성물의 도막강도와 내화학성이 현저하게 저하되는 문제가 발생된다.Preferably 1, 6-bis (2, 3- epoxy propoxy) hexane is used 10-20 parts by weight. When 1,6-bis (2,3-epoxypropoxy) hexane is used in less than 10 parts by weight, the effect of 1,6-bis (2,3-epoxypropoxy) hexane is negligible and exceeds 20 parts by weight. If used, the coating film strength and chemical resistance of the resin composition is significantly lowered.
ⅲ) 충진제Ⅲ) filler
: 삼산화안티몬(Antimony trioxide, Sb2O3), 실리카, 알루미나, 산화세륨, 지르코니아 등이 1종 이상 사용된다. : Antimony trioxide (Sb 2 O 3 ), silica, alumina, cerium oxide, zirconia and the like are used at least one.
삼산화안티몬은 난연성도 뛰어나고 분산성도 좋기 때문에 사용이 바람직하다. 실리카로는 흄드 실리카 분말(Fumed silica powder)이 사용된다. 흄드 실리카분말을 사용하면, 수지조성물의 저응력화에 한층 더 효과적이다. Antimony trioxide is preferred for its excellent flame retardancy and good dispersibility. As silica, fumed silica powder is used. Use of fumed silica powder is more effective in reducing the stress of the resin composition.
이러한 충전제의 사용량은 수지조성물의 저응력성 및 고온강도 등의 요구 물성에 따라 달라질 수 있는데, 바람직하게는 1~6중량부 사용된다. The amount of the filler may vary depending on the required physical properties such as low stress and high temperature strength of the resin composition, preferably 1 to 6 parts by weight.
ⅳ) 기타 첨가제Iii) other additives
: 소포제, 습윤제, 분산제 등과 같은 통상적인 첨가제 중에서 적절히 선택된다. : It is suitably selected from the usual additives, such as an antifoamer, a humectant, a dispersing agent, etc.
이들 첨가제의 구체적인 종류를 몇 가지 예시하면, 소포제로는 플루오르카본 변성중합체(Fluorocarbon-modified polymer)가 사용되는데, 예를 들면, 바스프(BASF)사의 제품명 FL3777, EFKA-8201 등이 사용된다. 그리고 습윤제로는 바스프(BASF)사의 EFKA-8502가 사용된다. Some examples of specific types of these additives include fluorocarbon-modified polymers as antifoaming agents. For example, BASF's product names FL3777, EFKA-8201, and the like are used. As the humectant, BASF's EFKA-8502 is used.
이들 첨가제는 통상적인 첨가량 수준으로 사용되나, 바람직하게는 소포제는 0.1~3중량부, 습윤제는 0.1~2중량부, 분산제는 0.1~2중량부 사용된다. These additives are used at conventional addition levels, but preferably 0.1 to 3 parts by weight of antifoaming agent, 0.1 to 2 parts by weight of wetting agent and 0.1 to 2 parts by weight of dispersant.
[경화제][Curing agent]
본 발명에 의한 경화제는 n-아미노에틸피페라진(n-aminoethylpiperazine) 15~35중량부, 1,3 벤젠디메탄아민(1,3 Benzenedimethanamine) 20~25중량부, 변성 지방족 아민 3~10중량부, 벤질알코올(benzyl alcohol) 3~15중량부, 비스페놀 A의 디글리시딜 에테르(diglycidly ether of bisphenol A) 5~15중량부를 포함한다.The curing agent according to the present invention 15 to 35 parts by weight of n-aminoethylpiperazine (n-aminoethylpiperazine), 20 to 25 parts by weight of 1,3 benzenedimethanamine (modified aliphatic amine 3 to 10 parts by weight) 3 to 15 parts by weight of benzyl alcohol, and 5 to 15 parts by weight of diglycidly ether of bisphenol A.
본 발명에 의한 경화제는 지방족 아민과 방향족 아민이 혼용되기 때문에 이들 아민의 특성이 조화롭게 형성되어 수지조성물에 적절한 물성을 제공한다. 특히, 지방족 아민과 방향족 아민이 상기와 같은 비율로 사용됨에 수지조성물이 도작작업에 필요한 적합한 가사시간을 가진다. Since the curing agent according to the present invention is mixed with aliphatic amines and aromatic amines, the properties of these amines are formed in a harmonious manner to provide appropriate physical properties to the resin composition. In particular, since the fatty amine and the aromatic amine are used in the above ratio, the resin composition has a suitable pot life required for the drawing operation.
또한, 본 발명에서는 변성 지방족 아민을 사용함으로써 수지조성물의 내수성이 향상된다. 사용가능한 변성 지방족 아민의 종류는 특별히 제한되지는 않는다. 예를 들어, 폴리에테르아민이 사용가능하다. Moreover, in this invention, the water resistance of a resin composition improves by using a modified aliphatic amine. The kind of modified aliphatic amine that can be used is not particularly limited. For example, polyetheramines can be used.
상기 벤질알코올(benzyl alcohol)은 비반응성 희석제로서, 주제와의 반응에 참여하지 않으면서 수지조성물의 점도를 낮추고 도막에 유연성을 부여한다. 전술한 바와 같이, 벤질알코올은 3~15중량부 사용되는데, 벤질알코올이 3중량부 미만으로 사용되면 벤질알코올에 의한 효과를 기대하기 곤란하고, 벤질알코올이 15중량부를 초과하여 사용되면 다른 성분과의 전체적인 균형이 파괴되어 수지조성물의 전체적인 물성이 저하되므로 바람직하지 않다. The benzyl alcohol is a non-reactive diluent, which lowers the viscosity of the resin composition and imparts flexibility to the coating film without participating in the reaction with the subject. As described above, benzyl alcohol is used in 3 to 15 parts by weight, when benzyl alcohol is used in less than 3 parts by weight it is difficult to expect the effect by benzyl alcohol, when benzyl alcohol is used in excess of 15 parts by weight It is not preferable because the overall balance of is broken and the overall physical properties of the resin composition are lowered.
상기와 같은 조성을 가지는 주제와 경화제는 1 : 0.5~1중량비로 혼합되는데, 주제와 경화제가 이러한 비율로 혼합될 때 조성물의 점도, 내열성, 내구성, 시공성 등이 가장 우수하다. The main ingredient and the hardener having the composition as described above are mixed in a 1: 0.5 to 1 weight ratio, and when the main ingredient and the hardener are mixed in such a ratio, the composition has the best viscosity, heat resistance, durability, workability, and the like.
이상과 같이 본 발명은 희석제를 포함하는 주제와 경화제에 의해 제조됨으로써 종래의 에폭시수지 조성물과 달리 냄새가 없고, 경화성도 좋을 뿐만 아니라 기계적 물성 및 화학적 물성도 우수하다. 이러한 본 발명에 의한 에폭시수지조성물은 코팅용 뿐만 아니라 각종 성형체의 성형원료로도 유용하다. As described above, the present invention is prepared by a main agent and a curing agent including a diluent, and thus, unlike conventional epoxy resin compositions, has no odor, good curing properties, and excellent mechanical and chemical properties. The epoxy resin composition according to the present invention is useful not only for coating but also as a molding material for various molded articles.
