Description
본 발명은 무용제(無溶劑) 우레탄수지계와 무기질계를 결합하여 제조한 친환경 무기질계 복합 난연성 바닥재 조성물 및 상기 조성물을 이용한 바닥재 시공방법에 관한 것이다.The present invention relates to an environment-friendly inorganic composite flame retardant flooring composition prepared by combining a solvent-free urethane resin system and an inorganic system and a flooring construction method using the composition.
각종 건물이나 공공기관의 공간, 학교시설물 등의 바닥에는 테라조(일명 도기다시)바닥, 목재마루, 에폭시계 또는 우레탄계 바닥재가 널리 사용되고 있다. Terrazzo (aka earthenware) flooring, wood flooring, epoxy or urethane flooring are widely used for floors of various buildings, public institutions, and school facilities.
테라조는 대리석 석회암의 세밀한 쇄석(碎石)을 골재로 하여 시멘트와 혼합해서 평평히 발라서 굳히고 표면을 갈아서 광택을 낸 것으로서 골재인 쇄석과 시멘트 안료에 의해 여러 가지로 색채와 광택을 낼 수 있으므로 대리석 대용품으로 건축, 공예에 많이 사용되어 왔으며, 특히 원료의 배합이나 시공방법의 발달로 사용범위가 확대되어 왔다. 그러나 테라조 바닥은 시간이 지날수록 미세 분진이 발생하여 인체에 해로운 영향을 미친다. Terrazzo is a fine aggregate of crushed stone of marble limestone, mixed with cement, applied flat, hardened, ground, polished, and aggregated. It has been used a lot in construction and crafts, and its range of use has been expanded, especially due to the formulation of raw materials and development of construction methods. However, the terrazzo floor has a harmful effect on the human body by the generation of fine dust over time.
한편, 목재마루는 친 환경적이지만 화재와 수분, 습도에 취약하고 또 목재의 부패방지를 위하여 가공시 방부용 약품을 사용하므로 포름알데히드와 같은 유해물질이 배출되는 문제가 있다. On the other hand, wood flooring is environmentally friendly, but vulnerable to fire, moisture, humidity, and because the use of antiseptic chemicals during processing to prevent the corruption of wood, there is a problem that harmful substances such as formaldehyde is discharged.
에폭시계 또는 우레탄계 바닥재는 시공단가는 저렴하지만 화재시 유독물질을 배출하여 인명피해의 주원인이 되고 있다. 또 콘크리트와 같은 무기질계 바닥면과 재질이 상이하므로 부착성이 떨어져 외부 충격이나 수축 및 팽창에 따른 박리 및 크랙 발생이 심하다. Epoxy-based or urethane-based flooring is cheaper in construction cost, but it causes toxic substances in case of fire, which is the main cause of human injury. In addition, since the base material is different from the inorganic base such as concrete, the adhesion is poor, and peeling and cracking are severe due to external impact, shrinkage and expansion.
따라서 화재시에도 유독물질을 발생하지 않음으로써 인명 피해를 크게 줄일 수 있고 또 외부 충격이나 수축 및 팽창시에도 크랙이나 박리되지 않는 바닥재와 이 바닥재를 이용한 시공기술의 개발이 요구되고 있다. Therefore, it is possible to greatly reduce the damage to human life by not generating toxic substances in fire, and to develop a flooring material that does not crack or peel off during external impact, shrinkage, or expansion, and construction technology using the flooring material is required.
본 발명은 상기와 같은 문제점을 해결하기 위하여 창안된 것으로서 무기질계로 이루어진 액상수지와 시멘트와 실리카의 혼합물인 시멘트와 실리카 혼합 파우더 및 경화제를 혼합하여 제조된 친환경 무기질계 복합 난연성 바닥재 조성물 및 상기 조성물을 이용하여 바닥을 시공하는 바닥재 시공방법에 관한 것이다.The present invention has been made to solve the above problems, using an environmentally friendly inorganic composite flame retardant flooring composition and the composition prepared by mixing a mixture of cement and silica which is a mixture of a liquid resin and a cement and silica and a curing agent made of an inorganic system It relates to a flooring construction method of constructing the floor.
본 발명에 의하여 시공된 바닥은 무기질계와 시멘트를 결합하였으므로 콘크리트보다 2배 이상의 강도를 가지며, 또 시멘트와 실리카 혼합 파우더는 시멘트와 실리카의 혼합물로서 바닥 콘크리트와 같은 재질이므로 서로 잘 접착되어 강한 충격에 의한 박리나 떨어짐이 없다. 또 무용제(無溶劑) 타입으로 친환경적인 제품으로 난연, 불연성이며 화재시 유독가스 배출이 없으며 산, 알칼리, 염, 용제 등에 대한 내화학성이 우수하다.Since the floor constructed by the present invention combines inorganic and cement, the floor has more than twice the strength of concrete, and the cement and silica mixed powder is a mixture of cement and silica. There is no peeling and fall off. In addition, it is a non-solvent type, eco-friendly product that is flame retardant, non-flammable, emits no toxic gases in case of fire, and has excellent chemical resistance against acids, alkalis, salts and solvents.
주차장에 시공한 경우에는 자동차 타이어와의 마찰에 의한 소음 발생이 현저하게 줄어든다. When installed in a parking lot, the noise generated by friction with the car tires is significantly reduced.
본 발명은 무기질계로 이루어진 액상수지와 시멘트와 실리카의 혼합물인 시멘트와 실리카 혼합 파우더 및 경화제를 혼합하여 제조된 바닥재 조성물 및 상기 조성물을 이용하여 바닥을 시공하는 바닥재 시공방법에 관한 것이다.The present invention relates to a flooring composition prepared by mixing a cement and silica mixture powder and a curing agent, which is a mixture of a liquid resin, cement and silica, and a flooring construction method using the composition.
이하, 본 발명에 대하여 상세하게 설명한다. EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.
우선 본 발명의 바닥재 조성물은 무기질계로 이루어진 액상수지와 시멘트와 실리카의 혼합물인 시멘트와 실리카 혼합 파우더 및 경화제를 혼합하여 제조된다. First, the flooring composition of the present invention is prepared by mixing a cement and silica mixed powder and a curing agent, which are a mixture of a liquid resin and a cement and silica, which are made of an inorganic system.
액상수지는 폴리에스테르수지(Polyester Resin), 탈이온수(Deionized Water), 이산화 티타늄(Titanium Dioxide) 및 비결정질 실리카(Amorphous Silica)를 혼합하여 이루어진 백색의 액상 수지이다.The liquid resin is a white liquid resin obtained by mixing polyester resin, deionized water, titanium dioxide and amorphous silica.
폴리에스테르수지는 다가(多價) 카르복시산과 다가 알코올의 축합 중합으로 얻는 고분자 화합물로서 일반 수지 중에서 가장 결성성이 높은 소재로 알려져 있다. 그 결과 스크래치가 잘 생기지 않으며, 내약품성이 뛰어나다. 따라서 산, 알카리, 염 및 용제 등의 화학물질에 대한 저항성이 우수하다. 또 열에 강하다. Polyester resin is a high molecular compound obtained by condensation polymerization of polycarboxylic acid and polyhydric alcohol and is known as the most highly formed material among general resins. As a result, scratches are less likely to occur and the chemical resistance is excellent. Therefore, it has excellent resistance to chemicals such as acids, alkalis, salts and solvents. It is also resistant to heat.
본 발명의 액상의 수지에는 폴리에스터 수지 35∼60 중량%를 배합하였다. 35-60 weight% of polyester resins were mix | blended with the liquid resin of this invention.
탈 이온수는 공업용수 ·음료수 등으로 이용할 목적으로 수중의 무기염류를 제거한 순수한 물에 가까운 고품위의 물을 가리킨다. 보통 이온교환수지가 사용되며, 수소형 강한 산성 양이온교환수지와 수산형 약한 염기성 음이온교환수지를 병용해서 만든다. 이것에 의해 천연수에 포함된 나트륨 ·칼슘 등 양이온과, 염소이온 ·황산이온 등 음이온이 제거된다. Deionized water refers to high quality water close to pure water from which inorganic salts are removed from water for the purpose of using it for industrial water, beverage water, and the like. Usually, ion exchange resin is used, and it is made by using hydrogen type strong acid cation exchange resin and hydroxyl type weak basic anion exchange resin. This removes cations, such as sodium and calcium, and anions, such as chlorine and sulfate, contained in the natural water.
본 발명의 액상의 수지에는 탈 이온수 25∼40 중량%를 배합하였다. 25-40 weight% of deionized water was mix | blended with the liquid resin of this invention.
이산화티타늄은 무색 또는 백색 분말로서 냄새와 맛이 없다. Titanium dioxide is a colorless or white powder with no odor and taste.
화학식은 TiO2 이다. 물, 염산, 묽은 황산, 알코올 및 다른 유기용매에 녹지 않는다. 상기 성질을 활용하기 위하여 본 발명의 액상수지에 첨가한 것이다.The chemical formula is TiO2. Insoluble in water, hydrochloric acid, dilute sulfuric acid, alcohol and other organic solvents. It is added to the liquid resin of the present invention in order to utilize the above properties.
본 발명의 액상의 수지에는 이산화티타늄 14∼20 중량%를 배합하였다. 14-20 weight% of titanium dioxide was mix | blended with the liquid resin of this invention.
비결정질 실리카는 고온에 견디며 팽창률이 아주 작고 급격한 열변화에 강하기 때문에 내열(耐熱)유리의 주재료가 된다. 본 발명에서는 이 내열성을 이용하기 위하여 첨가한 것이다. Amorphous silica is the main material of heat-resistant glass because it withstands high temperatures, has a very small expansion rate and is resistant to rapid thermal changes. In this invention, it adds in order to utilize this heat resistance.
본 발명의 액상수지에는 비결정질 실리카 1∼5 중량%를 배합하였다. 1 to 5% by weight of amorphous silica was blended into the liquid resin of the present invention.
따라서 본 발명의 액상수지는 폴리에스테르수지 35∼60 중량%와 탈이온수 25∼40 중량%, 이산화티타늄 14∼20 중량% 및 비결정실리카 1∼5 중량%로 이루어진다. Therefore, the liquid resin of the present invention is composed of 35 to 60% by weight of polyester resin, 25 to 40% by weight of deionized water, 14 to 20% by weight of titanium dioxide and 1 to 5% by weight of amorphous silica.
이어 포틀랜드 시멘트와 실리카(모래)를 배합하여 본 발명의 바닥재 조성물의 골재에 해당되는 시멘트와 실리카 혼합파우더를 제조하였다. 따라서 시멘트와 실리카 혼합 파우더는 바닥 콘크리트와 같은 재질이다. Portland cement and silica (sand) were blended to prepare a cement and silica mixture powder corresponding to the aggregate of the flooring composition of the present invention. Therefore, cement and silica mixed powder is the same material as floor concrete.
포틀랜드 시멘트는 1824년 영국의 J.애스프딘이 제조법을 발명한 시멘트로, 그 경화체(硬化體)가 영국의 포틀랜드섬에서 생산되는 돌과 비슷하기 때문에 이 같은 이 름을 붙였다. 주성분은 석회·실리카·알루미나·산화철(酸化鐵) 등이다. 일반적으로 시멘트라고 하면 이것을 말하며, 생산량의 대부분을 차지하고 있다.Portland cement is the cement invented in 1824 by J. Asphdin, England, and so named because its hardened body resembles the stone produced on Portland, England. Main components are lime, silica, alumina, iron oxide, and the like. In general, cement refers to this, and accounts for most of the production.
본 발명의 시멘트와 실리카 혼합파우더에는 포틀랜드 시멘트 30∼50 중량%를 배합하였다. The cement and silica mixed powder of the present invention was blended with 30 to 50% by weight of Portland cement.
실리카(모래)는 이산화규소(SiO2)라고도 하며 지각에서 가장 풍부한 원소인 규소와 산소로 이루어진 화합물이다. 실리카는 포틀랜드 시멘트와 배합하여 콘크리트를 구성한다.Silica (sand), also called silicon dioxide (SiO2), is a compound composed of silicon and oxygen, the most abundant elements in the earth's crust. Silica is combined with Portland cement to form concrete.
본 발명의 시멘트와 실리카 혼합파우더에는 실리카 50∼70 중량%를 배합하였다. In the cement and silica mixed powder of the present invention, 50 to 70 wt% of silica was blended.
따라서 본 발명의 시멘트와 실리카 혼합파우더는 포틀랜드 시멘트 30∼50 중량%와 실리카 50∼70 중량%를 배합하여 이루어진다.Therefore, the cement and silica mixed powder of the present invention is made by mixing 30 to 50% by weight of Portland cement and 50 to 70% by weight of silica.
이어 상기 액상수지 15∼25 중량%와 상기 시멘트와 실리카 혼합파우더 65∼70 중량% 및 경화제 10∼15 중량%를 혼합하여 바닥재 조성물을 제조하였다. 경화제로는 폴리메틸 폴리페닐 이소시아네이트(Polymethylen Polyphenyl Isocyanate)를 사용하였다. 폴리메틸 폴리페닐 이소시아네이트는 벤젠의 유도체로서 분자 중에 이소시아네이트(NCO)를 가지고 있는 갈색의 액체로서 점성(粘性)이 강하므로 경화제로서 적합하다.Subsequently, 15-25 wt% of the liquid resin, 65-70 wt% of the cement and silica mixing powder, and 10-15 wt% of the curing agent were mixed to prepare a flooring composition. As a curing agent, polymethylen polyphenyl isocyanate was used. Polymethyl polyphenyl isocyanate is a brown liquid having isocyanate (NCO) in the molecule as a derivative of benzene, and is suitable as a curing agent because of its high viscosity.
이와 같이 조성된 바닥재 조성물은 바닥재로 시공하였을 때 전술한 바의 효과를 가지고 있어 바닥재로서 매우 유용하다. The flooring composition thus prepared has an effect as described above when constructed as a flooring material is very useful as a flooring material.
본 발명의 바닥재와 에폭시계 바닥재의 물성을 비교하여 보면 다음과 같다.When comparing the physical properties of the flooring material and the epoxy-based flooring of the present invention are as follows.
이어 본 발명의 바닥재 조성물로 바닥재를 시공하는 시공방법에 대하여 설명한다. Next, the construction method for constructing the flooring material with the flooring composition of the present invention will be described.
우선 본 발명의 바닥재 조성물을 시공할 바탕 면을 정지한다. 신축 현장인 경우에는 바탕 면의 콘크리트가 최소 28일 이상 양생되어 콘크리트가 충분히 굳은 후에 시공하여야 바탕 면의 변형이 없다. 보수 현장인 경우에는 바탕 면의 균열을 보수하고 또 훼손된 부분은 복구한 후에 작업을 실시한다.First, the base surface on which the flooring composition of the present invention is to be constructed is stopped. In the case of a new construction site, the base surface should be cured for at least 28 days and the concrete should be solidified before construction. In the case of a repair site, repair work is to be done after repairing cracks in the base surface and repairing damaged parts.
이어 바탕 면을 깨끗이 청소한 후에 접착제로서 프라이머를 균일하게 도포한다. The base surface is then thoroughly cleaned and then the primer is evenly applied as an adhesive.
이어 액상수지 15∼25 중량%와 시멘트와 실리카 혼합파우더 65∼70 중량% 및 경화제 10∼15 중량%를 혼합하여 바닥재 조성물을 제조한다. 상기 조성물의 배합은 전동 교반기를 사용하는 것이 바람직하며, 3분 이상 충분히 배합하여 준다.Subsequently, 15-25 wt% of the liquid resin, 65-70 wt% of the cement and silica mixing powder, and 10-15 wt% of the curing agent are mixed to prepare a flooring composition. It is preferable to use the electric stirrer for mix | blending of the said composition, and will mix | blend enough for 3 minutes or more.
이어 상기 바닥재 조성물을 1∼3mm 두께로 1차 도포한 후 경화시킨다. Subsequently, the flooring composition is first applied to a thickness of 1 to 3 mm and then cured.
이어 상기 1차 도포된 바닥재 조성물이 완전히 경화되면 상기 도포면을 샌딩하여 표면을 거칠게 한 후 1차와 같은 방법으로 2차로 바닥재 조성물을 도포하여 총 두께가 2∼5mm가 되도록 한다. 이와 같이 1차와 2차로 나누어 바닥재 조성물을 도포하는 이유는 1차와 2차를 한번에 작업하면 기포가 많이 발생하여 바닥 면이 고르게 형성되지 않기 때문이며, 또 1차 도포된 표면을 거칠게 하는 이유는 2차로 도포되는 바닥재 조성물이 1차 도포된 바닥 면에 잘 부착되도록 하기 위한 것이다. Subsequently, when the primary applied flooring composition is completely cured, the coated surface is sanded to roughen the surface, and then the bottoming composition is applied secondly in the same manner as the first so that the total thickness is 2 to 5 mm. The reason for applying the flooring composition by dividing the primary and secondary in this way is that when the primary and the secondary work at once, a lot of bubbles are generated so that the bottom surface is not evenly formed. The flooring composition to be applied to the car is intended to adhere well to the first applied floor surface.
한편, 바닥재의 두께는 3mm일 경우가 가장 경제적이면서도 바닥재로서의 역할을 충분히 수행할 수 있다. 바닥재의 두께가 3mm 미만일 경우에는 바닥재로서의 내구성이 떨어지며 3mm 이상일 경우에는 필요이상으로 자재를 사용하는 결과가 되어 비경제적이다. On the other hand, the thickness of the flooring is 3mm is the most economical but can fully play a role as the flooring. If the thickness of the flooring material is less than 3mm, durability as a flooring material is inferior, and if the thickness of the flooring material is more than 3mm, it is uneconomical as a result of using the material more than necessary.
이어 상기 2차로 도포된 바닥재 조성물위에 칼라 칩을 뿌린 후 완전히 경화시킨다. 칼라 칩을 뿌리는 이유는 테라조에서와 같이 다양한 무늬를 형성할 수 있고 또 미끄럼을 방지할 수 있도록 하기 위한 것이다. 칼라 칩은 규산소다와 필러, 안료 및 첨가제 같은 인체에 해가 전혀 없는 아크릴 합성수지로 제조되는 바, (주)꼬레프에서 생산되는 제품을 구입하여 사용하였다. Then sprinkled with color chips on the second applied flooring composition is completely cured. The reason for spraying the color chip is to be able to form various patterns and to prevent slipping as in terrazzo. Color chips are made of acrylic synthetic resins, which are harmless to the human body, such as sodium silicate, fillers, pigments and additives.
이어 상기 도포면에 탑 코팅제를 배합하여 도포한 후 경화시킨다. Subsequently, the top coating agent is blended and applied to the coated surface to cure.
탑 코팅제는 상기 액상수지 80∼90 중량%와 상기 경화제 10∼20 중량%를 혼합하여 제조하며, 탑 코팅제를 도포하면 표면에 피막을 형성하여 매끈하고 광택이 나므로 외관을 미려하게 해준다. 또 탑 코팅제는 외부 충격을 일차로 흡수하므로 바닥의 균열이나 스크래칭을 막아주며 산, 알카리 또는 용제 등 화학물질에 의한 훼손을 막아준다.The top coating agent is prepared by mixing 80 to 90% by weight of the liquid resin and 10 to 20% by weight of the curing agent. When the top coating agent is applied, a film is formed on the surface to make the appearance smooth and glossy. In addition, the top coating absorbs external impacts primarily, preventing cracks and scratches on the bottom and preventing damage to chemicals such as acids, alkalis or solvents.
그러므로 본 발명은 액상수지 15∼25 중량%와 시멘트와 실리카 혼합파우더 65∼70 중량% 및 경화제 10∼15 중량%를 혼합하여 이루어지는 것을 특징으로 하는 친환경무기질계 복합난연성 바닥재 조성물을 제공한다.Therefore, the present invention provides an environment-friendly inorganic composite flame retardant flooring composition comprising 15 to 25% by weight of a liquid resin, 65 to 70% by weight of cement and silica mixed powder, and 10 to 15% by weight of a curing agent.
