투수 콘크리트의 칼라 코팅방법 및 이에 사용되는 칼라 코팅재Color coating method of permeable concrete and color coating material used therein

제1도는 본 발명에 의한 투수 콘크리트의 칼라 코팅 고정을 도시한 블록도.1 is a block diagram showing the color coating of the pitched concrete according to the present invention.

제2도 a,b,c,d도는 본 발명의 각 공정에 따른 노면의 단면구조도.Figure 2 a, b, c, d is a cross-sectional view of the road surface according to each step of the present invention.

본 발명은 투수 콘크리트의 칼라 코팅방법 및 이에 사용되는 칼라 코팅재에 관한 것으로, 상세하게는 물과 혼합한 시멘트에 무기질 안료와 아크릴수지 및 고유동화제를 첨가한 칼라 코팅재를 투수 콘크리트의 표면에 도포시키고, 그 위에 비닐을 덮어 로울러 등으로 가볍게 눌러 문지른 후 양생시키고, 비닐을 제거함으로서 투수 콘크리트의 표면 강도를 강화시키는 동시에 투수 콘크리트의 표면을 선명한 색상으로 도포할 수 있도록 한 투수 콘크리트의 칼라 코팅방법 및 이에 사용되는 칼라 코팅재에 관한 것이다.The present invention relates to a color coating method of permeable concrete and a color coating material used therein. Specifically, a color coating material including an inorganic pigment, an acrylic resin, and a high fluidizing agent in cement mixed with water is coated on the surface of the permeable concrete. Covering the vinyl on it, rubbing it with a roller, etc., rubbing it to cure, and removing the vinyl to strengthen the surface strength of the permeable concrete and at the same time to apply the vivid color of the permeable concrete to a color coating method, and It relates to a color coating used.

투수 콘크리트는 차도나 보도, 또는 옥외 주차장과 같이 노면의 배수를 요하는 곳에 타설하여 우천시 노면의 빗물이 내부로 스며들어 지면으로 배출될 수 있도록 한 것으로, 근래에는 투수기능과 함께 투수 콘크리트를 유색처리하여 노면의 구획 및 외관의 미려도를 높이도록 하고 있다.Pitched concrete is installed in places that require drainage of roads such as roads, sidewalks, or outdoor parking lots, so that rainwater from the road surface can penetrate into the interior and be discharged to the ground. In order to improve the beauty of the partition and the appearance of the road surface.

상기한 바와 같은 투수 콘크리트의 칼라 코팅방법으로는 안료가 첨가된 투수 콘크리트를 직접 타설하거나, 투수 콘크리트를 타설한 후 그 표면만을 유색 시멘트나 에폭시등으로 도포하므로써 소정의 색상을 갖도록 하게 되는데, 투수 콘크리트에 안료를 직접 첨가하는 전자의 경우에는 표면만을 착색할 수 없어 타설할 투수 콘크리트의 양에 비례하여 일정비율로 안료를 첨가해야 하므로 안료의 사용량이 많아지게 되고 이로 인한 경제적 손실이 배가 될 뿐만 아니라 생산시에는 안료가 포함된 유색 폐수가 발생되므로 폐수 처리에 어려움이 있었고, 포장공사시에는 주위에 묻을 염려가 있었으며, 시멘트의 탄산칼슘(CaCO3) 성분에 의한 백화 현상으로 인하여 선명한 칼라를 얻기가 어려웠다.As the color coating method of the permeable concrete as described above, by pouring the pigment-added permeable concrete directly, or after pouring the permeable concrete to have a predetermined color by coating only the surface with colored cement or epoxy, permeable concrete In the case of the former which directly adds the pigment to the pigment, only the surface cannot be colored, so the pigment must be added at a constant proportional to the amount of permeable concrete to be poured, so the amount of the pigment is increased and the economic loss is doubled. In the city, it was difficult to treat the wastewater due to the generation of colored wastewater containing pigments, and there was a risk of being buried around during the paving process, and it was difficult to obtain a vivid color due to the whitening phenomenon caused by the calcium carbonate (CaCO 3 ) component of the cement. .

또한 투수 콘크리트를 타설한 후 그 표면만을 에폭시등으로 코팅하는 후자의 경우에는 코팅재로 사용되는 에폭시와 시멘트의 수축률이 상이하기 때문에 내구성이 자하되고, 에폭시에 혼합되어 있는 신나 등의 혼합제가 공기를 오염시키게 되며 표면이 미끄러운 문제점이 있었으며, 시멘트와 안료를 혼합한 코팅재를 사용하는 경우에는 시멘트에 함유된 탄산칼슘(CaCO3)이 외부로 표출되는 백화현상에 의해 색상이 선명하지 않고, 스프레이 살포가 불가능하였으며, 도포층이 투수 콘크리트로부터 박리되는 등의 문제점이 발생되었다.In addition, in the latter case where the surface of the permeate concrete is coated with epoxy or the like, the shrinkage of the epoxy and cement used as the coating material is different, so the durability is self-contained, and a mixture of thinner and the like contaminated with air contaminates the air. There was a problem that the surface is slippery, and when the coating material mixed with cement and pigment is used, the color is not vivid due to the whitening phenomenon in which the calcium carbonate (CaCO 3 ) contained in the cement is exposed to the outside, and spray spraying is impossible. Problems occurred such that the coating layer peeled from the permeable concrete.

한편, 투수 콘크리트는 공극율이 12% 이상으로 규정되어 있으며, 일반적으로는 내부 공극율이 13-17%정도이고 표면의 공극율이 30-50% 정도로 표면의 공극이 크기 때문에 거칠어 보이고 공극에 이물질이 쉽게 메워져 투수 효과가 저하되기 때문에 공극에 메워진 이물질을 진공청소기에 의해 용이하게 제거할 수 있어야 하는데 종래의 투수 콘크리트에 있어서는 이물질이 내부로 들어가 박히게 되어 진공청소기로도 제거하기 어렵기 때문에 진공청소기에 의한 투수력 회복 효과가 저하되는 문제점이 있었다.On the other hand, permeable concrete is defined to have a porosity of 12% or more. Generally, the surface porosity is about 13-17% and the surface porosity is about 30-50%. Since the permeation effect is reduced, foreign matters filled in the voids should be easily removed by a vacuum cleaner. However, in conventional permeable concrete, foreign substances enter the interior and become lodged and difficult to be removed by a vacuum cleaner. There was a problem that the effect is reduced.

본 발명은 이와 같은 점을 감안하여 안출한 것으로서 투수 콘크리트의 공극을 줄여 이물질이 공극을 막음으로서 투수력이 저하되는 것을 방지할 수 있게 하고, 투수성에는 관계없이 투수 콘크리트의 표면 강도를 증대시키는 동시에 칼라 투수 콘크리트의 생산시 공정에서 안료를 투입할 필요가 없게 하여 폐수 발생을 억제할 수 있을 뿐만 아니라 표면이 미끈하게 처리되고, 투수 콘크리트 전체를 칼라화하는데서 생기는 과도한 안료의 손실을 최소화하여 경제적인 투수 콘크리트의 칼라 코팅방법을 제공하는 것을 주목적으로 한다.The present invention has been made in view of such a point, and by reducing the voids of the permeable concrete, it is possible to prevent the permeability from being lowered by blocking foreign matters, and to increase the surface strength of the permeable concrete regardless of permeability, and at the same time, In the production of pitched concrete, it is not necessary to add pigments in the process to suppress waste water generation, and the surface is smoothed, and the economical pitched concrete is minimized by minimizing the loss of excessive pigments generated by colorizing the whole pitched concrete. The main object of the present invention is to provide a color coating method.

본 발명의 다른 목적은 투수 콘크리트 표면의 공극을 내부 공극인 13-17% 정도로 줄임으로서 표면의 상태가 고르면서 선명한 칼라를 낼 수 있게 하기 위한 것이다.Another object of the present invention is to reduce the voids on the surface of the permeable concrete surface by about 13-17% of the internal voids, so that the surface of the surface can be uniform and have a clear color.

본 발명의 또 다른 목적은 투수 콘크리트의 투수성을 저해하지 않고 저렴한 비용으로 선명한 색상과 우수한 강도로 투수 콘크리트의 표면을 유색으로 코팅처리할 수 있도록 한 투수 콘크리트의 칼라 코팅재를 제공하기 위한 것이다.Still another object of the present invention is to provide a color coating material of water-permeable concrete, which enables to color-coating the surface of water-permeable concrete with vivid color and excellent strength at low cost without impairing the water-permeability of the water-permeable concrete.

상술한 본 발명의 목적은 물 및 시멘트와 내후성이 우수한 무기질 안료 그리고 접착력을 증대시키는 동시에 시멘트의 백화현상을 방지하며 강도를 높여주는 수용성 아크릴 수지, 스프레이 살포를 용이하게 하기 위한 고성능 분사제인 계면활성제 계통의 나프탈린으로 제조된 고유동화제(콘크리트 혼화제)를 혼합한 칼라 코팅재를 투수 콘크리트를 표면에 살포하고, 그 위에 비닐을 덮어 비닐 표면을 가벼운 페인트 로울러로 및 붓으로 가볍게 눌러주고 양생한 후 비닐을 제거하는 투수 콘크리트의 칼라 코팅방법에 의하여 달성되어진다.The object of the present invention described above is water and cement, inorganic pigments having excellent weather resistance, and water-soluble acrylic resins to prevent cement whitening and increase strength while increasing adhesion, and a surfactant system which is a high-performance propellant for facilitating spray spraying. Spray the pitcher concrete onto the surface with a color coating material mixed with a high fluidizing agent (concrete admixture) made of Naphthalin, and lightly press the vinyl surface with a light paint roller and a brush after curing the vinyl. It is achieved by the color coating method of permeable concrete to be removed.

이하 본 발명을 공정별로 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by process.

제1공정 : 투수 콘크리트를 포설 후 다짐한다.First step: Pitch after laying permeable concrete.

제2공정 : 물중량비 50-80%에 시멘트 중량비 50-20%, 그리고 고형분 50% 기준의 수용성 아크릴 수지를 중량비로 물 사용량의 10-50%를 혼합하며, 여기에 시멘트 사용량의 20% 이내의 무기질 안료와 시멘트 사용량의 2-5% 범위의 고유동화제를 혼합한 칼라 코팅재를 페인트 살포용 스프레이로 포설 후 다짐한 투수 콘크리트 표면에 두께 2mm 이하로 살포한다.2nd process: water-soluble acrylic resin based on 50-80% of water by weight, 50-20% of cement by weight, and 50% by solid content of 10-50% of water is mixed by weight, and within 20% of the amount of cement Color coating material mixed with inorganic pigment and high fluidizing agent in the range of 2-5% of the amount of cement used is sprayed with paint spraying spray and then sprayed to below 2mm thickness on compacted concrete surface.

상기 칼라 코팅재는 강도 저하의 문제가 있으므로 혼합후 1시간 이내에 사용하여야 한다.Since the color coating material has a problem of strength deterioration, it should be used within 1 hour after mixing.

상기 수용성 아크릴 수지는 접착력을 증대시키는 동시에 시멘트의 백화현상을 방지하기 위하여 혼합하는 것이며, 고유동화제는 고성능 분사제인 계면활성제 계통의 나프탈린으로 제조된 것으로 칼라 코팅재를 묽게 함으로서 스프레이로 용이하게 살포할 수 있게 해주는 역활을 한다.The water-soluble acrylic resin is mixed to increase the adhesion and at the same time to prevent the whitening of the cement, the high fluidizing agent is made of naphthalin of a surfactant-based high-performance propellant, and can be easily sprayed by diluting the color coating material It can play a role.

제3공정 : 칼라 코팅재를 투수 콘크리트 표면에 살포한 후 습기가 증발하기 전에 비닐로 표면을 덮고 페인트용 로울러 또는 붓등으로 가볍게 눌러준다.Step 3: After spreading the color coating on the surface of the permeable concrete, cover the surface with vinyl and press lightly with paint roller or brush before moisture evaporates.

이렇게 표면의 습기가 증발되기 전에 비닐을 덮고 가볍게 눌러주면 표면이 평탄해지는 동시에 표면공극이 줄어들게 된다.If you cover the vinyl and press it lightly before the moisture on the surface evaporates, the surface becomes flat and the surface voids are reduced.

또한 살포된 칼라 코팅재의 수분은 투수 콘크리트의 슬럼프에서 흡수되고 일부는 표면으로 증발되어 비닐에 맺혀서 투수 콘크리트에 지속적으로 수분이 공급되게 됨으로서 우수한 양생 효과를 나타내게 되어 투수 콘크리트의 강도가 증대되게 된다.In addition, the moisture of the sprayed color coating material is absorbed in the slump of the pitched concrete, and part of the water is evaporated to the surface of the vinyl to form a continuous water supply to the pitched concrete exhibits an excellent curing effect to increase the strength of the pitched concrete.

제4공정 : 비닐을 가볍게 눌러준 후, 24시간 이상 양생하고 표면의 비닐을 벗겨내게 되면 투수 콘크리트의 칼라 코팅 작업이 완료되게 되는 것이다.4th step: After lightly pressing the vinyl, curing over 24 hours and peeling off the surface of the vinyl, color coating of the permeable concrete is completed.

상기와 같은 공정을 거쳐 칼라 코팅 작업이 완료된 투수 콘크리트는 선명한 색상을 나타내게 되는 동시에 아크릴 수지의 특성에 따른 광택을 유지할 뿐만 아니라 표면 공극이 작아 표면 강도가 증가되고, 굵은 입자의 불투과로 내구성이 향상되는 특성을 나타내게 된다.The water-permeable concrete, which has completed the color coating process through the above process, displays vivid colors and maintains gloss according to the characteristics of the acrylic resin, and the surface strength is small due to the small surface voids, and the durability is improved by the impermeability of coarse particles. It will become a characteristic.

면적 100m3의 주차장의 주차공간 50m3를 녹색으로 하고, 차도인 50m3는 적색의 투수 콘크리트로 하며 투수 콘크리트의 압축 강도를 210kg/cm2로 포장하는 경우의 실시예를 상세히 설명하면 다음과 같다.An embodiment of the case where the parking space of the parking lot having an area of 100m 3 is 50m 3 in green, the driveway 50m 3 is the red permeable concrete, and the compressive strength of the permeable concrete is packed at 210kg / cm 2 is as follows. .

제4공정; 페인트 로울러로 표면을 눌러준 후 24시간 경과후 비닐을 벗겨내고 투수 콘크리트를 충분히 양생하여 교통을 개방하게 되면 미려한 칼라 투수 콘크리트가 완성되게 된다.4th process; After 24 hours of pressing the surface with the paint roller, the vinyl is peeled off and the permeable concrete is fully cured to open the traffic and the beautiful colored permeable concrete is completed.

이와 같이 된 본 발명의 투수 콘크리트의 칼라 코팅 방법은 일반 콘크리트 포장방법에도 적용할 수 있음은 물론이며, 투수 콘크리트의 투수성은 내부 공극에 의하여 결정되므로 칼라 코팅재의 살포전에 다짐공정에 의하여 표면공극을 줄인다고 하여도 투수 계수가 전체적으로 떨어지지 않는다.The color coating method of the permeable concrete of the present invention as described above can be applied to general concrete pavement methods, and the permeability of the permeable concrete is determined by the internal voids, so that the surface voids are reduced by the compaction process before spraying the color coating material. Even if the permeability coefficient does not drop as a whole.
