Description
본 발명은 항균수지조성물에 관한 것으로서, 보다 상세하게는 항균성이 우수한 새로운 조성의 항균수지조성물에 관한 것이다.The present invention relates to an antibacterial resin composition, and more specifically, to an antibacterial resin composition of a new composition with excellent antibacterial properties.
사람들은 일상생활에서 각종 병원균에 노출된다. 특히, 각종 물품들이 많은 사람들에 의해 연속적으로 취급되고 접촉되면서 사람들이 기하급수적으로 병원균에 감염되어 집단감염이 발생되며, 세계적으로 감염병이 대유행하게 되는 팬데믹이 초래되기도 한다. People are exposed to various pathogens in their daily lives. In particular, as various items are continuously handled and contacted by many people, people are exponentially infected with pathogens, resulting in group infections, which can lead to a global pandemic.
일상생활에서 병원균에 감염되는 것을 방지하기 위해 항균특성을 가지는 성형원료로 제품을 성형하거나 또는 항균특성을 가지는 코팅제로 표면을 코팅처리하기도 한다. 그러나 일상생활에서 병원균에 감염되는 것을 좀 더 효과적으로 방지하기 위해서는 우수한 항균특성이 장기간 지속적으로 유지되는 제품을 제조할 필요가 있다. To prevent infection with pathogens in everyday life, products are molded with molding raw materials with antibacterial properties, or the surface is coated with a coating with antibacterial properties. However, in order to more effectively prevent infection with pathogens in daily life, it is necessary to manufacture products that maintain excellent antibacterial properties for a long period of time.
한편, 에폭시수지계 수지는 다른 종류의 수지에 비해 접착성, 내수성, 내약품성, 내마모성, 내후성 등의 물성이 우수한 장점을 가지기 때문에 적용가능한 분야가 제한되지 않고 다양한 분야에 적용될 수 있는 장점을 가진다. On the other hand, epoxy resin-based resins have superior physical properties such as adhesion, water resistance, chemical resistance, abrasion resistance, and weather resistance compared to other types of resins, so the applicable fields are not limited and have the advantage of being applicable to a variety of fields.
본 발명은 상기와 같은 점에 착안하여 제안된 것으로서, 은계 무기항균제가 함유되어 인체에 무해하면서도 지속적이고 우수한 항균성을 가지므로, 위생적인 환경을 조성할 수 있는 새로운 조성의 항균수지조성물을 제공하는 것이다.The present invention was proposed in consideration of the above points, and provides an antibacterial resin composition of a new composition that can create a hygienic environment because it contains a silver-based inorganic antibacterial agent and is harmless to the human body while having persistent and excellent antibacterial properties. .
본 발명의 특징에 따르면, 주제부와 경화제부가 2:1중량비로 배합되어 이루어지며, 상기 주제부는 비스페놀 A 다이글리시딜 에테르 75~85중량부; 1,6-비스(2,3-에폭시프로폭시)헥산 5~15중량부; 및 은계 무기항균제 0.1~0.3중량부;를 포함하며,According to a feature of the present invention, the main part and the hardener part are mixed at a weight ratio of 2:1, and the main part includes 75 to 85 parts by weight of bisphenol A diglycidyl ether; 5 to 15 parts by weight of 1,6-bis(2,3-epoxypropoxy)hexane; And 0.1 to 0.3 parts by weight of a silver-based inorganic antibacterial agent;
상기 경화제부는 벤질알코올 10~30중량부; 1,3-사이클로헥산디메탄아민 8~10중량부; 및 5-아미노메틸-1,2,3-트라이메틸사이클로헥세인메탄아민 8~10중량부;를 포함하는 것을 특징으로 하는 항균수지조성물이 제공된다.The curing agent part includes 10 to 30 parts by weight of benzyl alcohol; 8 to 10 parts by weight of 1,3-cyclohexanedimethanamine; and 8 to 10 parts by weight of 5-aminomethyl-1,2,3-trimethylcyclohexanemethanamine. An antibacterial resin composition is provided.
본 발명의 다른 특징에 따르면, 상기 은계 무기항균제는 은-제올라이트 항균제, 은-지르코늄 항균제 중에서 적어도 1종 이상을 포함한다. According to another feature of the present invention, the silver-based inorganic antibacterial agent includes at least one of a silver-zeolite antibacterial agent and a silver-zirconium antibacterial agent.
이상과 같은 구성을 가지는 본 발명은 은계 무기항균제가 함유되어 인체에 유해성이 적고 우수한 항균특성이 장기간 지속적으로 유지되는 장점을 가진다. 본 발명은 공예품, 싱크대, 타일 등의 건축용 마감재 등과 같은 다양한 제품의 성형 원료 또는 다양한 제품들의 표면을 마감처리하는 코팅제로도 사용이 가능한데, 본 발명으로 성형되거나 코팅된 제품들은 본 발명에 의해 지속적이고 우수한 항균력을 가지게 된다. 따라서 본 발명으로 성형, 코팅된 제품들을 사용하면 위생적인 생활환경 조성에 도움이 된다.The present invention, which has the above configuration, has the advantage of containing a silver-based inorganic antibacterial agent, causing less harm to the human body, and maintaining excellent antibacterial properties for a long period of time. The present invention can be used as a molding raw material for various products such as crafts, sinks, architectural finishing materials such as tiles, etc., or as a coating agent for finishing the surface of various products. Products molded or coated with the present invention are sustainable and durable by the present invention. It has excellent antibacterial activity. Therefore, using products molded and coated with the present invention helps create a hygienic living environment.
또한, 본 발명은 에폭시수지를 기반으로 하여 내마모성, 내약품성, 내후성, 내수성 등의 물성도 우수하기 때문에 적용가능한 분야가 크게 제한되지 않고 다양한 분야의 제품에 적용이 가능한 장점도 가진다. In addition, since the present invention is based on an epoxy resin and has excellent physical properties such as abrasion resistance, chemical resistance, weather resistance, and water resistance, the applicable fields are not greatly limited and it has the advantage of being applicable to products in various fields.
이하에서 본 발명을 좀 더 구체적으로 설명한다. Hereinafter, the present invention will be described in more detail.
본 발명은 주제부와 경화제부로 이루어지는 2액형 에폭시수지계 조성물로서, 주제부와 경화제부의 구체적인 조성을 살펴보면 다음과 같다. The present invention is a two-component epoxy resin composition consisting of a main part and a hardener part. The specific composition of the main part and the hardener part is as follows.
1) 주제부1) Topic section
주제부는 비스페놀 A 다이글리시딜 에테르, 1,6-비스(2,3-에폭시프로폭시)헥산, 은계 무기항균제를 포함한다.The main part includes bisphenol A diglycidyl ether, 1,6-bis(2,3-epoxypropoxy)hexane, and silver-based inorganic antibacterial agent.
비스페놀 A 다이글리시딜 에테르(Bisphenol A diglycidyl ether)는 주제부의 주성분이다. 바람직하게는 비스페놀 A 다이글리시딜 에테르는 주제부 100중량부에 대해 75~85중량부 포함되는데, 비스페놀 A 다이글리시딜 에테르가 75중량부 미만이면 본 발명의 접착력이 과도하게 저하되고, 84중량부를 초과하면 다른 성분들에 비해 비스페놀 A 다이글리시딜 에테르의 함량이 과도하게 높아져서 본 발명의 전체적인 물성의 저하가 초래되므로 바람직하지 않다. Bisphenol A diglycidyl ether is the main component of the main component. Preferably, bisphenol A diglycidyl ether is included in an amount of 75 to 85 parts by weight based on 100 parts by weight of the main part. If the amount of bisphenol A diglycidyl ether is less than 75 parts by weight, the adhesive strength of the present invention is excessively reduced, and 84 If the amount exceeds parts by weight, the content of bisphenol A diglycidyl ether becomes excessively high compared to other components, which is undesirable because it results in a decrease in the overall physical properties of the present invention.
상기 1,6-비스(2,3-에폭시프로폭시)헥산(1,6-Bis(2,3-epoxypropoxy)hexane)은 용제로서, 주제부 100중량부에 대해 5~15중량부 포함된다. 1,6-비스(2,3-에폭시프로폭시)헥산이 5중량부 미만이면 주제부를 이루는 성분들의 충분히 분산되지 못하며, 15중량부를 초과하면 본 발명의 점도가 과도하게 저하되어 흐름성이 증가하는 문제가 발생된다. The 1,6-Bis(2,3-epoxypropoxy)hexane is a solvent and is included in an amount of 5 to 15 parts by weight based on 100 parts by weight of the main component. If the amount of 1,6-bis(2,3-epoxypropoxy)hexane is less than 5 parts by weight, the components forming the main part cannot be sufficiently dispersed, and if it exceeds 15 parts by weight, the viscosity of the present invention is excessively lowered and the flowability is increased. A problem arises.
한편, 상기 은계 무기항균제(Silver-base inorganic antimicrobial agent)는 은-제올라이트 항균제 또는 은-지르코늄 항균제로 이루어지거나 이들의 혼합물로 이루어진다. 본 발명은 은계 무기항균제에 의해 항균성을 가진다. Meanwhile, the silver-base inorganic antimicrobial agent consists of a silver-zeolite antimicrobial agent or a silver-zirconium antimicrobial agent, or a mixture thereof. The present invention has antibacterial properties by using a silver-based inorganic antibacterial agent.
일반적으로 유기항균제는 인체에 대한 안정성의 문제를 야기하는 반면 무기항균제는 유기항균제와 달리 인체에 무해한 장점을 가지며, 유기항균제에 비해 지속성이 길고 내성균을 발생시키지 않는 장점을 가진다. 따라서 본 발명은 이러한 장점을 가지는 무기항균제를 사용하되, 특히, 가장 우수한 항균력을 가지는 금속으로 알려진 은이온이 제올라이트, 지르코늄 등의 무기담체에 담지된 은계 무기항균제를 사용함으로써, 인해에 무해하면서도 우수한 항균성이 지속적으로 유지되는 장점을 가진다. In general, organic antibacterial agents cause safety problems for the human body, while inorganic antibacterial agents have the advantage of being harmless to the human body, unlike organic antibacterial agents, and have the advantage of lasting longer and not generating resistant bacteria compared to organic antibacterial agents. Therefore, the present invention uses an inorganic antibacterial agent that has these advantages, and in particular, uses a silver-based inorganic antibacterial agent in which silver ions, known as the metal with the best antibacterial activity, are supported on an inorganic carrier such as zeolite and zirconium, thereby providing harmless and excellent antibacterial properties. This has the advantage of being continuously maintained.
이러한 은계 무기항균제는 주제부 100중량부에 대해 0.1~0.3중량부 포함된다. 은계 무기항균제가 0.1중량부 미만이면 소요되는 수준의 항균성을 기대하기 곤란하며, 0.3중량부를 초과하면 은계 무기항균제의 함량 대비 항균성 상승효과가 미미하므로 경제적인 측면에서 바람직하지 않다. These silver-based inorganic antibacterial agents are included in an amount of 0.1 to 0.3 parts by weight based on 100 parts by weight of the main component. If the amount of the silver-based inorganic antibacterial agent is less than 0.1 parts by weight, it is difficult to expect antibacterial activity at the required level, and if it exceeds 0.3 parts by weight, the synergistic antibacterial effect is minimal compared to the content of the silver-based inorganic antibacterial agent, so it is undesirable from an economic standpoint.
한편, 이러한 주제부에는 조성물의 물성을 향상시키기 위해 수지조성물에 통상적으로 사용되는 안료, 자외선 안정제, 개질제, 소포제, 레벨링제, 습윤제, 분산제, 난연제, 산화방지제 등과 같은 첨가제가 통상의 사용범위에서 적절량 추가로 함유될 수 있음은 당연하다. Meanwhile, in this main part, additives such as pigments, ultraviolet stabilizers, modifiers, antifoaming agents, leveling agents, wetting agents, dispersants, flame retardants, antioxidants, etc. commonly used in resin compositions to improve the physical properties of the composition are appropriate within the range of normal use. It is natural that additional amounts may be contained.
2) 경화제부2) Hardener section
경화제부는 벤질알코올, 1,3-사이클로헥산디메탄아민, 5-아미노메틸-1,2,3-트라이메틸사이클로헥세인메탄아민를 포함한다.The hardener part contains benzyl alcohol, 1,3-cyclohexanedimethanamine, and 5-aminomethyl-1,2,3-trimethylcyclohexanemethanamine.
상기 벤질알코올(Benzyl alcohol)은 용제로서, 경화제부 100중량부에 대해 10~30중량부 포함된다. 벤질알코올이 10중량부 미만이면 경화제부를 이루는 성분들이 충분히 분산되지 못하며, 30중량부를 초과하면 본 발명의 점도가 과도하게 저하되어 흐름성이 증가하는 문제가 발생된다. Benzyl alcohol is a solvent and is included in an amount of 10 to 30 parts by weight based on 100 parts by weight of the hardener.
