Description
본 발명은 2액형 에폭시 수지계 타일용 줄눈제로서 로비, 욕실, 베란다 등의 타일 줄눈부분에 적용하여 타일줄눈 시공 뒤 후속작업에 따른 각종 오염 및 건물 사용에 따른 곰팡이, 물때 등 이물질에 의한 오염에 대하여 뛰어난 저항성을 가지고, 오염이 되었더라도 간단한 물청소 정도로 쉽게 초기의 깨끗한 상태를 유지할 수 있도록 하는 내오염성이 뛰어난 타일용 줄눈제에 대한 것이다.The present invention is applied to tile joints such as lobby, bathroom, veranda, etc. as a two-component epoxy resin tile joints, and contaminated by foreign matters such as mold, scale, etc. It is about tile joints that have excellent resistance to fouling and have excellent resistance to contamination even if contaminated, so that it is easy to maintain an initial clean state easily with simple water cleaning.
건물의 내외장재 중에서 타일은 오염에 강하고 청소가 용이하며, 그 자체로 장식의 효과가 있어 건물의 로비, 화장실, 주택의 현관, 베란다 등의 마감재로 많이 적용되고 있다. 그러나, 적용되는 부위가 화장실처럼 물을 많이 쓰거나, 외부와 직접 연결되는 공간이 많아 각종 오염물질에 노출되기 쉬운 부위로 타일 자체는 오염에 강하고 청소가 용이하여 깨끗한 장식효과를 장시간 유지하지만 타일 사이의 줄눈의 경우는 시멘트계 줄눈으로 시공 시 외부의 각종 오염물질과 잦은 물사용으로 인한 곰팡이, 세균, 물 때 등에 의한 오염으로 쉽게 더러워지며, 본래의 상태로 되돌아갈 정도의 청소는 거의 불가능한 실정이다.Among the interior and exterior materials of the building, tiles are resistant to pollution and easy to clean, and because of their decorative effect, they are widely applied as finishing materials for the lobby of the building, the toilet, the porch of the house, and the porch. However, the applied area uses a lot of water like a toilet or directly connected to the outside, so it is easy to be exposed to various pollutants. The tile itself is resistant to contamination and is easy to clean. Joints are cement-based joints, which are easily polluted by various contaminants from outside and contamination by mold, bacteria, and water due to frequent use of water, and cleaning to the original state is almost impossible.
본 발명은 기존의 시멘트계 줄눈과는 달리 2액형 에폭시계 타일용 줄눈으로 완벽한 내오염성능, 방수성능 및 빠른 경화 등 에폭시 수지 자체의 장점으로 인하여 시공 중에 발생할 수 있는 오염, 긁힘, 패임 등과 사용 중에 발생할 수 있는 곰팡이, 물때 등 각종 이물질에 대하여 저항성이 강하고 오염이 되었더라도 간단한 청소로 오염물질을 제거하여 시공 초기의 깨끗한 상태를 거의 영구히 유지할 수 있는 내오염성이 뛰어난 타일용 줄눈제에 대한 것이다.The present invention is a two-component epoxy joint joint, unlike the conventional cement joint joint, due to the advantages of the epoxy resin itself, such as perfect pollution resistance, waterproof performance and rapid curing, it may occur during use, such as contamination, scratches, dents during construction It is resistant to various foreign matters such as mold, scale, and even if it is contaminated, it is about a stain-resistant tile joint with excellent stain resistance that can keep the clean state almost permanently at the initial stage of construction by simple cleaning.
타일용 줄눈은 초기에는 일반적으로 백시멘트 자체를 그대로 사용하였으나, 폭 5mm 이상의 베란다 등에 적용 시 균열이 발생하고 보수율이 떨어져 겨울 공사의 경우 양생불량이 발생하여 시멘트와 골재, 보습제를 첨가하여 이러한 문제들을 해결한 제품이 현재 거의 타일용 줄눈제의 대부분을 차지하고 있다. 그러나, 생활수준이 높아지면서 타일 줄눈 부분에 생기는 오염에 대하여 해결책을 찾게 되어, 항균/발수성분을 첨가하여 곰팡이나 물때발생을 줄인 특허 2001-0044300(항균발수 타일줄눈 몰탈 및 시공밥법)같은 제품들이 고급 제품으로 점차 나타나기 시작하였으나, 오염의 정도를 줄일 뿐 결국 오염이 발생하여 큰 호응을 얻지 못하고 있고, 특허 2004-0007055(타일줄눈제 조성물)와 같이 오염된 줄눈에 얇게 도포하여 오염부위를 가리는 역할을 하는 보수용 제품들도 있지만, 얇은 피막형 제품으로 쉽게 벗겨짐이 발생하여 거의 사용되지 못하고 있으며 오염원인에 대하여 근본적인 저항능력이 없어 현재의 기술로는 기존 제품과 기술로는 타일 줄눈의 오염을 완전히 막는 것은 불가능한 실정이다. 따라서, 내오염성이 뛰어난 타일용 줄눈에 대한 연구가 절실하다고 할 수 있다.Tile joints generally used the back cement itself in the early stages, but when applied to a porch with a width of 5mm or more, cracks occurred and the repair rate decreased, resulting in poor curing in the winter construction, and added cement, aggregate, and moisturizer. The resolved product now accounts for almost the majority of tile joints. However, as the standard of living increases, there is a solution to the contamination of tile joints, and products such as patent 2001-0044300 (antibacterial water repellent tile joint mortar and construction rice method) that reduce the occurrence of mold or scale by adding antibacterial / water repellent ingredients It began to appear gradually as a high-quality product, but it reduces the degree of contamination and eventually does not get a great response due to the occurrence of contamination, and serves to cover the contaminated area by applying a thin coating on the contaminated joint as in Patent 2004-0007055 (Tile Joint Composition). There are some repairing products, but the thin film type products are easily peeled off, so they are hardly used and there is no fundamental resistance against the causes of contamination. It is impossible to prevent. Therefore, it can be said that research on tile joints having excellent stain resistance is urgently needed.
점차 삶의 질이 높아짐에 따라 소비자의 주택의 인테리어에 대한 관심도 점차 높아지면서 쉽게 오염되고 청소는 늘 어려운 타일 줄눈에 대해서 다양한 요구가 발생하고 있다. 타일 줄눈은 타일과 타일 사이의 채움재로 항상 오염원에 노출되어 있어 열화속도가 매우 빠르며 습하게 젖어있는 경우가 많아 곰팡이 등에 쉽게 오염이 발생한다. 또한, 시멘트라는 재료는 다공질 재료로서 액상의 오염원에 의해 쉽게 침투당하며, 침투 후 공극속의 오염물질은 거의 제거가 불가능하다. 실리콘으로 발수기능을 부여하고, 항곰팡이제로 곰팡이에 대한 오염정도를 줄일 수 있으나 몰탈 자체에 좋은 영향을 주지 못하며, 오염의 시간을 늦춰줄 뿐, 완전히 오염에 대하여 자유롭지는 못한 실정이다.As the quality of life increases, consumers' interest in the interiors of their homes gradually increases, causing various demands on tile joints that are easily contaminated and difficult to clean. Tile joints are filling materials between tiles and are always exposed to pollution sources, so the deterioration rate is very fast, and they are often wet and easily polluted. In addition, the material called cement is a porous material, easily penetrated by the pollutant in the liquid phase, and it is almost impossible to remove contaminants in the pores after the penetration. Silicon gives water repellency and antifungal agent can reduce the contamination of mold, but it does not affect mortar itself, delays the time of contamination and is not completely free of contamination.
본 발명에서는 에폭시를 적용하여, 에폭시 자체의 특징인 빠른 경화 및 높은 강도로 타일시공 후 후속작업에 따른 발생 가능한 다양한 오염 및 긁힘, 패임 등에 대한 문제를 최소화하며, 완벽한 방수성 및 내화학성으로 각종 오염 물질에 대하여 강력한 저항력을 가지는 내오염성이 완벽한 타일줄눈을 개발하고자 한다.In the present invention, by applying the epoxy, it minimizes the problems of various contamination, scratches, dents, etc. that can occur in the subsequent work after the tile construction with the rapid curing and high strength, which is a characteristic of the epoxy itself, and various pollutants with perfect waterproof and chemical resistance We want to develop a perfect tile joint that has a strong resistance against fouling.
본 발명품은 기존 타일 줄눈제의 가장 큰 단점인 오염에 대한 문제를 해결하여 1번의 줄눈 시공으로 간단한 유지관리로 초기의 깨끗한 상태를 영구적으로 유지하는 것이 가능하도록 하였다. 유성에폭시를 기본으로 하여 물청소가 가능하도록 하여 기존의 줄눈 시공방법으로 시공이 가능하도록 개발된 제품으로 우수한 내오염성과 내화학성 내구성으로 쉽게 오염이 된 바닥 타일의 줄눈으로 적용하여 영구적인 깨끗한 타일 줄눈의 시공이 가능하도록 설계되었다.The present invention solved the problem of contamination, which is the biggest disadvantage of the conventional tile joints, and made it possible to permanently maintain the initial clean state by simple maintenance with one joint construction. It is a product developed to enable water cleaning based on oil-based epoxy, and can be applied by conventional joint construction methods.It is applied to joints of floor tiles that are easily contaminated with excellent pollution resistance and chemical resistance durability. It is designed to be installed.
내오염성이 뛰어난 타일용 줄눈제를 제조하기 위하여 본 발명은 에폭시 수지에 각종 첨가제 및 무기충전필러를 첨가한 주제부와 에폭시수지 경화제에 첨가제를 혼합한 경화제부로 나뉘며, 주제부와 경화제부를 주제부 95 : 경화제부 5의 중량비로 혼합하여 적용하는 특징을 가지며, 주제부와 경화제부를 자세히 설명하면 다음과 같다.In order to manufacture a tile joint having excellent stain resistance, the present invention is divided into a main part in which various additives and inorganic fillers are added to an epoxy resin, and a curing agent part in which an additive is mixed into an epoxy resin curing agent. : It has the characteristic to apply by mixing by weight ratio of the hardening | curing agent part 5, and a main part and a hardening | curing agent part are explained in detail as follows.
(1) 주제부(1) subject
10∼15중량％의 에폭시 수지, 0.1∼0.2중량％의 분산제, 0.05∼0.1중량％의 소포제, 0.1∼0.5중량％의 가소제, 0.5∼1.0중량％의 유화제, 3∼5중량％의 이산화티탄, 74∼80중량％의 무기충전필러, 3∼5중량％의 희석용제10 to 15 wt% epoxy resin, 0.1 to 0.2 wt% dispersant, 0.05 to 0.1 wt% antifoaming agent, 0.1 to 0.5 wt% plasticizer, 0.5 to 1.0 wt% emulsifier, 3 to 5 wt% titanium dioxide, 74 to 80 wt% inorganic filler, 3 to 5 wt% diluent
(2) 경화제부(2) hardener
82∼85중량％의 에폭시 수지 경화제, 0.5∼1.0중량％의 분산제, 14.2∼17.2중량％의 물82 to 85 weight% epoxy resin curing agent, 0.5 to 1.0 weight% dispersant, 14.2 to 17.2 weight% water
에폭시 수지는 분자량 또는 당량에 따라서 그 용도가 달라 질 수 있다. 에폭시 수지의 가장 기본적인 수지는 Bis-Phenol A형 에폭시 수지이고, 이외에도 Novolac, Brome, Rubber, Urethane 변성 수지들이 있으나, 저장안정성이 우수하고 경화 후 가교 밀도가 높아, 기계적, 화학적 물성이 우수하여 뛰어난 접착력을 발휘할 수 있도록 분자량이 200∼700 정도가 되는 저당량 수지로서 입도 크기가 1㎛이하로 작고, 고형분은 70∼90중량％이며, 에폭시 당량 100∼350g/eq의 비스페놀A형 에폭시 수지를 사용하는 것이 바람직하다.Epoxy resins may have different uses depending on molecular weight or equivalent weight. The most basic resin of epoxy resin is Bis-Phenol type A epoxy resin and Novolac, Brome, Rubber, and Urethane modified resins, but it has excellent storage stability and high crosslinking density after curing, and excellent mechanical and chemical properties. A low equivalent resin having a molecular weight of about 200 to 700, having a particle size of less than 1 μm, a solid content of 70 to 90 wt%, and an epoxy equivalent of 100 to 350 g / eq of bisphenol A type epoxy resin. It is preferable.
분산제는 조성물 중의 고형분들을 고르게 분산시키는 기능을 하는 것으로서 안료 친화그룹을 가진 고분자의 블록 공중합체 용액인 BYK사의 제품을 사용한다.The dispersant functions to evenly disperse the solids in the composition, and a product of BYK, which is a block copolymer solution of a polymer having a pigment affinity group, is used.
소포제는 조성물 중의 기포를 파포시키고 생성을 억제하는 첨가제로서, 소수성 실리카를 함유하는 폴리에테르-실록산 공중합체와 같은 통상의 비이온성 O/W(Oil in Water type) 에멀젼 등의 상용화된 제품이 사용될 수 있다.Antifoaming agent is an additive that traps bubbles in the composition and inhibits production, and commercialized products such as conventional nonionic oil in water type (O / W) emulsions such as polyether-siloxane copolymers containing hydrophobic silica may be used. have.
가소제는 에폭시 수지의 경화 후 경도를 부드럽게 하여 쉽게 깨지는 것을 방지하고, 가사시간을 연장시켜 주는 역할을 하나 에폭시 수지의 경화 후 성능에 영향이 크므로 사용량에 주의를 하여야 한다.Plasticizer prevents easily cracking by softening hardness after curing of epoxy resin and prolongs pot life, but care should be taken when using because it has a great effect on performance after curing of epoxy resin.
유화제는 유성 에폭시 수지를 유화하여 시공 뒤 기존 타일 줄눈 시공방법과 같이 물에 젖은 스폰지로 쉽게 닦일 수 있도록 하는데, 도움을 주는 첨가제로 첨가량이 적으면 스폰지로 쉽게 닦이지 않으며, 너무 많으면 에폭시 수지의 경화에 영향을 주고 경화 후에도 경도가 떨어지는 문제가 생길 수 있다. 비이온계 계면활성제 중 HLB값이 13∼13.5 범위의 제품을 적용한다.The emulsifier emulsifies the oil-based epoxy resin so that it can be easily wiped with a sponge wet with water like the conventional tile joint method. This can affect and reduce hardness even after curing. Products with HLB values in the range of 13 to 13.5 in nonionic surfactants are applied.
이산화티탄은 줄눈의 백색도를 높이고, 다른 색상을 내기 위한 안료첨가 시 색상을 더 잘 내도록 하기 위하여 첨가하는 첨가제로서, 수지 자체의 색상 및 황에 저항하기 위하여 골재의 색상에 따라 3∼5％ 정도의 첨가량이 필요하다. 3％ 미만이면 백색도가 너무 떨어지고, 5％ 이상이면 너무 백색도가 높아 눈에 피로를 줄 수도 있다.Titanium dioxide is an additive added to increase the whiteness of joints and to make the color better when adding pigments to produce other colors. It is 3 to 5% depending on the color of the aggregate to resist the color of the resin itself and sulfur. The amount of addition is necessary. If it is less than 3%, the whiteness is too low, and if it is 5% or more, the whiteness is too high and may cause eye fatigue.
무기충전 필러는 경량탄산칼슘, 탄산캄슘, 규사로 이루어지는데, 시공작업성 및 시공 후 미려한 줄눈 표면의 상태로 볼 때, 경량탄산칼슘 : 탄산칼슘 : 규사의 비율이 1 : 3∼4 : 8∼10의 비율이 가장 우수하였다. 비율이 달라지면 흐름이 발생하여 작업성이 떨어지고, 시공 후 표면상태가 매끄럽지 못하여 반드시 조성비를 지켜야 한다. 경량 탄산칼슘은 흡유가 (20±1)㎖/100g, 가사비중 (0.5±0.1)g/㎖인 것을 사용하고, 탄산칼슘(CaCO3 )은 흡유가 (25±3)㎖/100g, 평균 입도 (8±2)㎛, 가사비중 (0.7±0.1)g/㎖의 탄산칼슘을 사용하고, 규사는 천연사를 분쇄하여 얻은 것으로 에폭시의 경화반응에 영향을 줄 수 있는 이물질을 포함하지 않는 것을 사용해야 하며, 8호사 크기의 규사를 적용한다. 특히, 경량탄산칼슘의 비율은 흐름성을 방지하는 작업성에 큰 영향을 주므로 첨가량에 주의해야 한다.The inorganic filler is composed of light calcium carbonate, calcium carbonate, and silica sand, and the ratio of light calcium carbonate to calcium carbonate to silica sand is 1: 3-4: 8 ~ in terms of construction workability and beautiful joint surface after construction. The ratio of 10 was the best. If the ratio is different, the flow occurs and the workability is decreased, and the surface condition is not smooth after construction. Light weight calcium carbonate has oil absorption (20 ± 1) ml / 100g, household weight (0.5 ± 0.1) g / ml, and calcium carbonate (CaCO 3 ) has oil absorption (25 ± 3) ml / 100g, average particle size Calcium carbonate (8 ± 2) ㎛, potting ratio (0.7 ± 0.1) g / ml is used, and silica sand is obtained by pulverizing natural sand and should not contain foreign substances that may affect the curing reaction of epoxy. The 8 sand size sand silicate is applied. In particular, the ratio of the light calcium carbonate has a great influence on the workability to prevent flow, so pay attention to the amount of addition.
희석용제로는 용해력이 높은 알콜계의 반응성 용제 중 벤질알콜을 적용하였다. 용제는 비점이 낮아 휘발성이 크면, 시공 시 냄새가 많이 나고, 시간이 지남에 따라 작업성이 크게 달라져 하자 발생의 가능성이 있으며, 에폭시 수지 경화 전 휘발에 의해 수축이 발생하여 균열 등의 문제가 생기기 쉽다.As the diluting solvent, benzyl alcohol was applied among the reactive solvents of high alcohol solubility. If the solvent has a low boiling point and a high volatility, it smells a lot during construction, and the workability is greatly changed over time, which may cause defects.Shrinkage may occur due to volatilization before curing the epoxy resin, causing problems such as cracking. easy.
에폭시 수지 만으로는 그 물성이 나타날 수 없고, 에폭시 수지 경화제를 사용하여야 경화가 가능하며, 물성이 우수하게 나타난다. 에폭시 수지 경화제로는 주로 폴리아민, 폴리아마이드, 산 무수물 등이 쓰이나, 타일줄눈용 에폭시 경화제는 다른 경화제에 비해 황변이 적은 계통의 제품을 적용하여야 하며, 접착제보다는 긴 가사시간이 필요하므로 줄눈으로서의 가사시간이 확보되는 제품을 선정하여 적용하여야 한다. 본 발명에 적용된 경화제는 에폭시 특유의 황변이 적은 타입인 사이클로 알리파틱 아민(cyclo aliphatic amine)계 경화제과 지방족 아민 경화제 중 속경성이 있는 제품을 10 : 1∼2의 비율로 혼합하여 적용하였다. 지방족 아민 경화제는 주제부에 첨가된 용제, 유화제, 가소제 등이 첨가로 가사시간은 확보되나 경화가 종결되는 시간이 늦어져 이를 앞당겨 초기강도를 확보하고자 첨가하였다. 분산제는 주제부에 적용된 분산제와 동일한 BYK사의 제품을 사용한다.Epoxy resin alone can not exhibit the physical properties, it is possible to cure only by using an epoxy resin curing agent, excellent physical properties. Polyamine, polyamide, and acid anhydride are mainly used as epoxy resin curing agent. However, epoxy curing agent for tile joints should be applied to products with less yellowing than other curing agents, and it requires longer pot life than adhesives. This secured product should be selected and applied. The curing agent applied to the present invention was applied by mixing a cycloaliphatic amine-based curing agent and an aliphatic amine curing agent in a ratio of 10: 1 to 2, which is a type of yellowing characteristic of epoxy. Aliphatic amine curing agent was added to the solvent, emulsifier, plasticizer, etc. added to the main part to secure pot life, but it was added to secure the initial strength as the time for curing was delayed. Dispersants use the same BYK products as the dispersants applied to the topic.
물은 에폭시를 타일 줄눈제의 작업성으로 맞추기 위하여 증점시키기 위한 방법으로 14.2∼17.2중량％를 적용하였다. 물은 첨가량에 따라 작업성 및 에폭시 수지의 경화에 영향을 크게 주므로 첨가량을 주의한다.Water was applied 14.2 to 17.2% by weight as a method for thickening the epoxy to match the workability of the tile joint. Note that the amount of water greatly affects workability and curing of the epoxy resin depending on the amount added.
