Description

석분 함유 바닥용 에폭시 도료 조성물{Epoxy Paint Composition for Concrete Floor Coating Containing Mineral Fragments}Epoxy Paint Composition for Concrete Floor Coating Containing Mineral Fragments}

본 발명은 석분 함유 주차장 바닥용 에폭시 도료 조성물에 관한 것으로서, 더욱 상세하게는 후막형 에폭시 도료로서 무용제형이며 2액형인 것을 특징으로 하며, 운모, 규사, 오석, 장석, 화강암, 백운석, 옥, 맥반석, 산화티타늄 등의 광물질 파쇄물이 함유된 것을 특징으로 하는 도료 조성물에 관한 것이다.The present invention relates to an epoxy paint composition for a stone powder-containing parking lot floor, more specifically, a thick film-type epoxy paint, characterized in that it is a solvent-free and two-component type, mica, silica sand, feldspar, feldspar, granite, dolomite, jade, elvan. The present invention relates to a coating composition containing mineral crushed materials such as titanium oxide.

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 다양한 에폭시 바닥재 시스템이 적용되고 있는데, 그 중에서도 용제 에폭시 도료를 중, 상도 3회에 걸쳐 200 ∼ 400㎛의 두께로 롤러 도장하는 박막형 시스템과 무용제 에폭시 도료를 2㎜의 두께로 셀프-레벨링(self-leveling)타입으로 도장하는 후막형 시스템이 가장 대표적인 에폭시 바닥재 시스템이다.Currently, various epoxy flooring systems have been applied. Among them, a thin film system for roller coating a solvent epoxy paint with a thickness of 200 to 400 μm over three times of a top coat and a solvent-free epoxy paint with a thickness of 2 mm is used. Thick film type coating is the most representative epoxy flooring system.

그러나, 용제 에폭시 도료를 사용하는 상기 박막형 시스템의 경우에는 휘발성이 강한 용제를 다량으로 사용함에 따라 환경 오염을 유발할 뿐만 아니라 작업자의 건강에 매우 유해한 영향을 주게 된다. 최근 환경 오염에 대한 심각성이 크게 부각되면서 각종 규제(예를들면 VOC규제)를 통해 상기 용제의 사용을 크게 제한하고 있으며, 이에 따라 상기 용제를 대신하여 고고형 분화(High-solid), 더 나아가서는 무용제형(solvent-free)타입의 도료 개발이 더욱 절실히 요구되고 있는 실정이다. 또한, 상기 박막형 시스템의 경우에는 고형분 용적비가 낮은 용제형 도료의 특성으로 인해 바닥재로서의 기능을 갖기 위한 최소 200㎛의 도막을 얻기 위하여 최소 2회 이상의 도장이 요구됨에 따라, 1회 도장후 후속 도장을 위하여 상온에서 1일 정도의 건조과정이 반드시 필요하게 되고 이는 전체 공사비를 증가시키는 원인이 된다.However, in the case of the thin film type system using the solvent epoxy paint, the use of the highly volatile solvent not only causes environmental pollution but also has a very detrimental effect on the health of the worker. Recently, due to the seriousness of environmental pollution, the use of the solvent is greatly restricted through various regulations (for example, VOC regulation), and thus, high-solid, and moreover, can be used instead of the solvent. There is an urgent need for the development of solvent-free paints. In addition, in the case of the thin film type system, since at least two or more coatings are required to obtain a coating film having a minimum of 200 μm to have a function as a flooring material due to the characteristics of the solvent type paint having a low solids content ratio, subsequent coating is performed after one coating. In order to achieve a one-day drying process at room temperature is necessary, which increases the overall cost of construction.

상기와 같은 이유로 무용제 타입의 도료가 사용되고 있으나, 도막 외관은 양호하나 최종 도막 외관이 매끄러워서, 주차장 바닥재 등의 목적으로 이용되는 경우 타이어와 바닥면의 접촉면적이 넓기 때문에, 소음이 심하게 나는 문제점이 있어 왔다.Solvent-free paint is used for the above reasons, but the appearance of the coating is good, but the appearance of the final coating is smooth, and when used for the purpose of parking lot flooring, the contact area between the tire and the floor is wide, which causes a lot of noise. It has been.

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.

상기와 같은 문제점을 해결하기 위하여, 본 발명은 주차장 바닥재 등의 목적으로 사용되는 경우 타이어와 바닥면 간의 접촉면적을 감소시킴으로써, 소음을 현저히 절감하는 것을 목적으로 하고 있다. 또한, 기존 바닥재들의 커다란 문제점인 미끄러짐 현상을 방지하는 것을 목적으로 한다. 이러한 목적에 더불어, 내마모성, 접착력이 뛰어나며, 내약품성, 내산성, 내마모성이 우수한 바닥용 에폭시 도료 조성물을 제공하는 것이 목적이다.In order to solve the above problems, the present invention aims to significantly reduce noise by reducing the contact area between the tire and the bottom surface when used for the purpose of parking lot flooring and the like. In addition, an object of the present invention is to prevent slippage, which is a big problem of existing flooring materials. In addition to these objects, it is an object to provide an epoxy coating composition for floors that is excellent in wear resistance and adhesion, and excellent in chemical resistance, acid resistance and wear resistance.

상기와 같은 목적을 달성하기 위하여, 본 발명에 의한 에폭시 도료 조성물은 주차장 바닥용 에폭시 도료 조성물에 있어서, 석분을 5 내지 80중량% 함유한 것을 특징으로 한다.In order to achieve the above object, the epoxy paint composition according to the present invention is characterized in that it contains 5 to 80% by weight of stone powder in the epoxy paint composition for the parking lot floor.

상기한 본 발명에 의한 에폭시 도료 조성물에 있어서, 상기 석분은 크기가 10 내지 100μm인 것을 특징으로 한다.In the epoxy coating composition according to the present invention, the stone powder is characterized in that the size of 10 to 100μm.

상기한 본 발명에 의한 에폭시 도료 조성물에 있어서, 상기 석분은 크기가 40 내지 80μm인 것을 특징으로 한다.In the epoxy coating composition according to the present invention, the stone powder is characterized in that the size of 40 to 80μm.

상기한 본 발명에 의한 에폭시 도료 조성물에 있어서, 상기 도료는 2액형 무용제형 도료인 것을 특징으로 한다.In the epoxy paint composition according to the present invention described above, the paint is a two-component solvent-free paint.

상기한 본 발명에 의한 에폭시 도료 조성물에 있어서, 에폭시 수지 20-60중량%, 반응성 희석제 10-25중량% 및 안료 10-40중량%를 더 포함하는 것을 특징으로 한다.In the epoxy coating composition according to the present invention described above, 20 to 60% by weight of epoxy resin, 10 to 25% by weight of a reactive diluent and 10 to 40% by weight of a pigment are further characterized.

이하, 본 발명에 관하여 더욱 상세히 살펴본다.Hereinafter, the present invention will be described in more detail.

본 발명은 에폭시 수지, 반응성 희석제, 경화제, 안료 및 첨가제가 함유되는 통상의 바닥재 도료 조성물에 10 내지 100μm 크기의 석분을 함유함으로써, 바닥에 도포시 엠보싱 효과가 발생하여 바닥을 스치는 물체와의 접촉면이 현저히 감소하므로 소음을 감소시킬 수 있는 조성물에 관한 것이다.The present invention contains 10 to 100 μm of stone powder in a conventional floor coating composition containing epoxy resin, reactive diluent, curing agent, pigment, and additives, so that the contact surface with the object that rubs the floor occurs due to embossing effect. It relates to a composition that can significantly reduce noise and thus reduce it significantly.

여기서 석분이라 함은, 광물질을 의미하며, 화산암, 현무암 계통인 것이 바람직하며, 그 이외에도 안산암, 규사, 백운석 등이 사용될 수 있다. 화산암과 현무암 계통의 광물질은 내기공성이 있기 때문에 바람직하다. 구체적으로, 운모, 규사, 오석, 장석, 화강암, 백운석, 옥, 맥반석, 산화티타늄 등의 광물질 파쇄물을 사용할 수 있다. 이러한 석분은 크기가 10 내지 100μm인 것이 바람직하며, 더욱 바람직하게는 40 내지 80μm이다. 입자의 크기가 10μm 미만이면 엠보싱 효과가 떨어지게 되어 소음 절감의 효과를 충분히 나타낼 수 없다. 이러한 관점에서는 입자가 40μm 이상인 것이 더욱 바람직하다. 한편, 입자의 크기가 100μm를 초과하면 보호 및 충격완화의 효과가 적어진다. 이 관점에서는 80μm를 초과하지 않는 것이 특히 바람직하다. 석분의 함량은 전체 조성물에 대하여 5 내지 80중량%인 것이 바람직하다. 5중량% 미만인 경우에는 엠보싱 효과가 미미하며, 80중량%를 초과하면 제품의 안정성에 문제를 일으킨다.Here, the stone powder means a mineral material, and it is preferable that the volcanic rock and basalt line are used. In addition, andesite, silica sand, dolomite, etc. may be used. Volcanic and basalt minerals are preferred because they are porous. Specifically, mineral crushed materials such as mica, silica sand, five stones, feldspar, granite, dolomite, jade, elvan, and titanium oxide may be used. Such stone powder preferably has a size of 10 to 100 µm, more preferably 40 to 80 µm. If the particle size is less than 10μm, the embossing effect is reduced and the noise reduction effect cannot be sufficiently exhibited. It is more preferable that particle | grains are 40 micrometers or more from such a viewpoint. On the other hand, when the particle size exceeds 100 µm, the effects of protection and shock mitigation become less. It is especially preferable not to exceed 80 micrometers from this viewpoint. The content of stone powder is preferably 5 to 80% by weight based on the total composition. If it is less than 5% by weight, the embossing effect is insignificant, and if it exceeds 80% by weight, the stability of the product is caused.

본 발명에 사용되는 에폭시수지는 비스페놀 A와 비스페놀 F 등에 에피클로로히드린을 반응시켜 얻어지는 비스페놀 A형 에폭시 수지, 비스페놀 F형 에폭시 수지, 지환족 에폭시 수지, 지방족 에폭시 수지, 그리시딜 에스테르형 에폭시 수지, 노블락형 에폭시 수지 등이다. 상기한 에폭시 수지는 본 발명의 바닥재 도료 조성물 중에 20 ∼ 60 중량% 범위내에서 사용한다. 이때, 상기 에폭시수지의 함량이 20 중량% 미만이면 바닥재의 도막 물성이 떨어지게 되며, 60 중량%를 초과하면 반응형 희석제의 함량이 증가하게 되는데, 반응성 희석제의 함량이 지나치게 많을 경우 전체적인 물성 특히 내화학성이 저하되는 문제점이 발생한다. 무용제 바닥재 용도로의 물성을 고려한다면 에폭시 수지로는 비스페놀 A형 에폭시 수지와 비스페놀 F형 에폭시 수지가 바람직하다.The epoxy resin used in the present invention is a bisphenol A type epoxy resin, a bisphenol F type epoxy resin, an alicyclic epoxy resin, an aliphatic epoxy resin, a glycidyl ester type epoxy resin obtained by reacting epichlorohydrin with bisphenol A, bisphenol F, etc., And a noblock type epoxy resin. Said epoxy resin is used in 20 to 60 weight% of range in the flooring coating composition of this invention. At this time, if the content of the epoxy resin is less than 20% by weight, the coating material properties of the flooring material is lowered, if the content of more than 60% by weight is increased the content of the reactive diluent, if the content of the reactive diluent is too much, the overall physical properties, particularly chemical resistance This deterioration problem occurs. In consideration of physical properties for solvent-free flooring, bisphenol A type epoxy resins and bisphenol F type epoxy resins are preferable.

비반응성 희석제는 기본적으로 수지의 고점도로 인한 작업의 제한성을 극복할 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 도료조성물 중에 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. When the content is more than 10% by weight, the coating film properties such as hardness are lowered.

본 발명에서 사용되는 경화제는 상기한 바와 같은 에폭시 수지를 실온에서 경화시킬 수 있는 실온 경화성 경화제이다. 본 발명에서는 상기 경화제로 알리파틱아민, 아미도아민, 아로마틱아민, 언하이드라이드, 폴리이소시아네이트, 폴리메르캅탄 및 폴리설파이드 등을 사용할 수 있다. 실온 경화를 위한 경화제의 함량에 대해서는 특정한 한정이 필요치 않으며 적정량을 사용할 수 있고, 본 발명에서는 바닥재 도료조성물 중의 에폭시수지의 에폭사이드기와 경화제의 활성수소가 1 : 1로반응하도록 사용하는 것이 바람직하다. 만일, 경화제의 함량이 지나치게 많을 경우 미반응한 프리아민이 대기중의 수분과 반응하여 내수성이 저하되고 도막 외관이 불량해질 수 있으며, 상기 경화제의 함량이 지나치게 적을 경우에는 에폭사이드의 미반응으로 인해 내용제성이 저하된다.The curing agent used in the present invention is a room temperature curable curing agent capable of curing the above-mentioned epoxy resin at room temperature. In the present invention, as the curing agent, aliphatic amine, amido amine, aromatic amine, anhydride, polyisocyanate, polymercaptan, polysulfide and the like can be used. There is no particular limitation on the content of the curing agent for room temperature curing, and an appropriate amount can be used, and in the present invention, it is preferable to use the epoxy resin in the floor coating composition so that the active hydrogen of the curing agent reacts with 1: 1. If the content of the curing agent is excessively high, unreacted preamine reacts with moisture in the air, thereby deteriorating the water resistance and poor coating appearance, and when the content of the curing agent is too small, due to the unreacted epoxide. Solvent resistance is lowered.

본 발명에서는 첨가제로 불포화카르복실산 타입의 분산제와 폴리실록산 타입의 소포제를 각각 바닥재 도료 조성물 중에 0.1 ∼ 3.0 중량% 범위내에서 사용할 수 있다. 만일 상기 분산제와 첨가제의 함량이 0.1 중량% 미만이면 도료 조성물의 저장성이 불량해지고, 함량이 3.0 중량%를 초과하면 건조 도막에 결함이 발생할 수 있다.In the present invention, as the additive, an unsaturated carboxylic acid type dispersant and a polysiloxane type antifoaming agent can be used in the floor coating composition, respectively, within the range of 0.1 to 3.0% by weight. If the content of the dispersant and the additive is less than 0.1% by weight, the storage property of the coating composition is poor, and if the content is more than 3.0% by weight, defects may occur in the dry coating film.

이하, 본 발명을 하기 실시예 및 실험예에 의거하여 상세히 설명하지만, 본 발명이 하기 실시예에 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail based on the following Examples and Experimental Examples, but the present invention is not limited to the following Examples.
