Description
본 발명은 콘크리트로 형성된 면은 물론 콘크리트 블럭, ALC 블럭, PC 판넬, ALC 판넬, 아코텍 판넬로 형성된 바탕면 조정에 사용될 수 있는 바탕조정 도장재에 관한 것으로, 좀 더 구체적으로는 시멘트 40 ∼ 60중량%, 체구멍 0.6mm 통과분의 미세골재 30 ∼ 50중량%, 무수석고 또는 탄산칼슘 분말 4 ∼ 10중량%, 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지 4 ∼ 5중량%, 증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 섬유질 혼화제 0.2 ∼ 0.3중량%로 구성됨을 특징으로 하는 시멘트계 콘크리트 면처리용 바탕조정 도장재에 관한 것이다.The present invention relates to a surface adjustment coating material that can be used to adjust the surface formed of concrete as well as concrete blocks, ALC blocks, PC panels, ALC panels, Akotech panels, and more specifically, 40 to 60 weight cement %, 30 to 50% by weight of fine aggregates with a body pore diameter of 0.6 mm, 4 to 10% by weight of anhydrous gypsum or calcium carbonate powder, acrylic, vinyl acetate type, ethylene vinyl acetate type or synthetic rubber type reemulsified powder resin 4 to 5% The present invention relates to a ground-based coating material for cement-based concrete surface treatment comprising a weight%, a thickener 0.2 to 0.3 weight%, a dispersant 0.1 to 0.2 weight%, an antifoaming agent 0.1 to 0.2 weight%, and a fiber admixture 0.2 to 0.3 weight%.
콘크리트를 사용하여 축조되는 대부분의 건축물에서는 거푸집 시스템 정밀도의 한계, 콘크리트 타설시 과도한 진동기(바이브레이타) 사용으로 인한 면판의 변형 및 재료적 특성때문에 콘크리트면에 곰보, 거푸집 패널 연결부의 패임 및 배부름 현상 등이 발생한다.In most buildings constructed using concrete, the dents and placement of the concrete panels and the formwork panel connections due to the limitations of formwork accuracy, the deformation of the faceplate and the material properties due to the use of excessive vibrators (vibrators) when placing concrete Phenomenon occurs.
따라서, 콘크리트를 타설하고 경화시킨후 거푸집을 분리한 다음, 콘크리트면을 평탄하게 만들기 위한 면처리공사(통칭, "견출공사"라고도 함)를 행하고 있다.Therefore, after the concrete is poured and hardened, the formwork is separated, and a surface treatment work (commonly referred to as "detection work") is performed to flatten the concrete surface.
즉, 형성된 콘크리트면에서 곰보부위 메움 및 배부름을 제거하고 거푸집 조인트선 부위는 10cm 내외의 폭으로 시멘트 풀칠에 의한 방법으로 콘크리트 면처리 공사를 시행하여 오고 있다.That is, the concrete surface treatment work has been carried out by removing the filling and filling of the bare part from the formed concrete surface and the cement joint line part by cement paste with a width of about 10 cm.
또한, 일반적으로 사용되고 있는 콘크리트 면처리 공사는 현장에서 순수 시멘트에 보수제를 첨가하여 물과 반죽한 시멘트 풀을 만들어 붓으로 칠하는 방법을 사용하고 있다.In addition, commonly used concrete surface treatment construction is using a method of making a cement paste kneaded with water by adding a repair agent to the pure cement in the field and painting with a brush.
그러나, 시멘트 풀칠에 의한 콘크리트 면처리 공사는 콘크리트면의 완벽한 평활도를 확보하기가 어려울 뿐만 아니라 시멘트 풀의 재료도 순수 시멘트만을 현장에서 배합하여 사용하기 때문에 수화열 및 건조수축으로 인한 균열 및 들뜸 현상이 발생하기 쉽고 공사시에는 분진 발생 등으로 마감공사의 효율성 저하와 품질확보에 어려움을 겪고 있다.However, the concrete surface treatment work by cement paste is difficult to ensure perfect smoothness of the concrete surface, and only the cement paste material is used in the field of pure cement, so cracking and lifting occurs due to heat of hydration and drying shrinkage. It is easy to be easy and has difficulty in securing the efficiency and quality of finishing work due to dust generation.
또한, 현장 배합이기 때문에 시멘트와 보수제의 혼합상태가 불균일하여 혼합할때마다 물성이 다르게 나타난다.In addition, because of the in-situ formulation, the mixed state of the cement and the repair agent is non-uniform, and thus the physical properties are different each time.
예를 들어, 시멘트 : 모래 = 1 : 2의 배합비를 갖는 시멘트 몰탈의 경우에 경화건조수축율은 타설 후 1주까지는 10 × 10-4, 1주에서 3주에는 0.5 ×10-4를 나타내는데, 순수 시멘트 풀의 경화건조수축율은 더욱 높을 것으로 추측되어 종래의 방법에 의한 콘크리트 면처리 공사에서 균열과 들뜸, 분진 발생 현상은 당연한 것으로 판단되며, 불가피하게 하자 보수 또는 재공사 부위가 많이 발생하여 공사비의 추가 상승 요인이 되고 있다.For example, in the case of cement mortar with a cement: sand = 1: 2 ratio, the hardening shrinkage rate is 10 × 10 -4 for 1 week after pouring and 0.5 × 10 -4 for 1 to 3 weeks. Hardening and drying shrinkage rate of cement paste is expected to be higher, so the phenomenon of cracking, lifting, and dust is natural in the concrete surface treatment work by the conventional method. It is a rising factor.
결과적으로, 종래의 방법은 콘크리트 면 전체의 평활도를 일정하게 만들기 곤란하며, 표면에 붓칠 자국이 그대로 남아 육안상으로 미관을 저해하는 단점이 있고, 균열과 들뜸 및 분진 발생으로 인하여 페인트 마감공정이나 벽지 마감공정에 문제점을 발생시키는 등 만족스러운 효과를 발현하고 있지 못하다.As a result, the conventional method is difficult to make the smoothness of the entire concrete surface uniformly, and there is a drawback that the brush marks remain on the surface to visually impair the aesthetics, and due to cracks, lifting and dust generation, the paint finishing process or wallpaper It does not produce satisfactory effects such as problems in the finishing process.
그럼에도 불구하고, 현재까지 콘크리트 면처리 공사용으로 사용되는 품질이 균일화된 제품의 개발은 이루어진 바 없고, 분사식으로 적용되기 위한 제품 역시 개발된 바 없다.Nevertheless, there has been no development of uniform quality products used for concrete surface treatment work, and no products have been developed for spray application.
따라서, 본 발명의 목적은 콘크리트면에의 뛰어난 부착성과 균열억제 성능을 갖고 있을 뿐만 아니라 콘크리트면 전체를 분사식으로 도장하여 콘크리트면의 평활도를 향상시킬 수 있는 시멘트계 콘크리트 면처리용 바탕조정 도장재를 제공하는 데 있다.Accordingly, an object of the present invention is to provide a ground-adjusting coating material for cement-based concrete surface treatment which can improve the smoothness of the concrete surface by spraying the entire concrete surface as well as having excellent adhesion to the concrete surface and crack suppression performance. There is.
상기 목적을 달성하기 위하여 본 발명에서는 시멘트 40 ∼ 60중량%, 체구멍 0.6mm 통과분의 미세골재 30 ∼ 50중량%, 무수석고 또는 탄산칼슘 분말 4 ∼ 10중량%, 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지 4 ∼ 5중량%, 증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 섬유질 혼화제 0.2 ∼ 0.3중량%로 구성되는 시멘트계 콘크리트 면처리용 바탕조정 도장재를 제조하고, 이를 분사식으로 도장하므로서 콘크리트면의 평활도를 향상시키고, 콘크리트면과 마감재의 부착성을 향상시키므로써 현장에서 임의로 배합하여 사용하는 종래 공사방법에서 발생하는 제반 문제점들을 해결하고 품질 안정화 및 공사비 절감 효과를 얻을 수 있었다.In order to achieve the above object, in the present invention, 40 to 60% by weight of cement, 30 to 50% by weight of fine aggregates having a body hole of 0.6 mm, 4 to 10% by weight of anhydrous gypsum or calcium carbonate powder, acrylic, vinyl acetate, ethylene Cement-based concrete composed of 4-5% by weight of vinyl acetate- or synthetic rubber-based reemulsified powder resin, 0.2-0.3% by weight thickener, 0.1-0.2% by weight dispersant, 0.1-0.2% by weight defoaming agent, and 0.2-0.3% by weight fibrous admixture By manufacturing the surface-adjusting coating material for surface treatment and spraying it, it improves the smoothness of the concrete surface and improves the adhesion between the concrete surface and the finishing material. It was able to solve the problem and stabilize the quality and reduce the construction cost.
본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.
본 발명에 따른 시멘트계 콘크리트 면처리용 바탕조정 도장재는 시멘트 40 ∼ 60중량%, 체구멍 0.6mm 통과분의 미세골재 30 ∼ 50중량%, 무수석고 또는 탄산칼슘 분말 4 ∼ 10중량%, 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지 4 ∼ 5중량%, 증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 섬유질 혼화제 0.2 ∼ 0.3중량%로 구성되는 것으로 특징지워진다.Background adjustment coating material for cement-based concrete surface treatment according to the present invention is 40 to 60% by weight of cement, 30 to 50% by weight of fine aggregates with a 0.6 mm passage through the body, 4 to 10% by weight of anhydrous gypsum or calcium carbonate powder, acrylic, acetic acid 4 to 5% by weight of re-emulsified powder resin of vinyl type, ethylene vinyl acetate type or synthetic rubber type, 0.2 to 0.3% by weight of thickener, 0.1 to 0.2% by weight of dispersant, 0.1 to 0.2% by weight of antifoaming agent, and 0.2 to 0.3% by weight of fibrous admixture It is characterized as being constructed.
시멘트는 포틀란트 시멘트 사용을 기준으로 하였으며, 시멘트의 사용량이 40중량% 미만일 경우에는 제조된 도장재의 접착력이 저하되는 문제점이 있고, 60중량%를 초과할 경우에는 경화건조수축율이 높아져 균열, 들뜸 현상이 발생하는 단점이 있다.Cement is based on the use of Portland cement, and when the amount of cement used is less than 40% by weight, there is a problem that the adhesive strength of the prepared coating material is lowered. There is a disadvantage that the phenomenon occurs.
골재는 입도가 커질수록 시공두께가 두꺼워져 균열, 들뜸 현상이 발생할 수 있으므로 골재 거름체의 구멍을 0.6mm 체로 하여 전량 통과분만을 사용하였으며, 도장재를 이용하여 시공되는 두께가 1 ∼ 3mm가 되도록 하였다.As the aggregate size increases, the thickness of the aggregate increases, which may cause cracking and lifting. Therefore, only the total amount of passing through the hole of the aggregate filter body was used as a 0.6 mm sieve, and the thickness of the aggregate was 1 to 3 mm. .
골재는 시멘트의 사용량을 감소시키기 위한 것으로 골재의 사용량이 30중량% 미만일 경우에는 상대적으로 시멘트의 사용량이 높아지게 되어 경화건조수축율이 높아져 균열, 들뜸 현상이 발생하는 단점이 있으며, 50중량%를 초과할 경우에는 상대적으로 시멘트의 사용량이 감소되어 제조된 도장재의 접착력이 저하되는 문제점이 발생한다.Aggregate is used to reduce the amount of cement. When the amount of aggregate is less than 30% by weight, the amount of cement is relatively high, and the hardening shrinkage rate increases, resulting in cracking and lifting, and exceeding 50% by weight. In this case, the amount of cement used is relatively reduced, resulting in a decrease in adhesion of the manufactured coating material.
또한, 혼화재료로서 무기질계 분말을 사용하되 시멘트의 경화건조수축율을 고려하여 무수석고 또는 탄산칼슘 분말을 사용하였다.In addition, an inorganic powder was used as a mixed material, but anhydrous gypsum or calcium carbonate powder was used in consideration of the hardening drying shrinkage ratio of cement.
즉, 본 발명의 콘크리트 면처리용 바탕조정 도장재는 주재료가 시멘트이고, 시멘트의 사용량이 40 ∼ 60중량%이므로 경화건조수축율을 고려하지 않을 수 없는 바, 무수석고나 탄산칼슘 분말을 첨가하여 경화건조수축율을 감소시켰으며, 무수석고 또는 탄산칼슘 분말 4 ∼ 10중량%를 사용하므로서 경화건조수축율을 1% 이하로 감소시킬 수 있었다.In other words, the base adjustment coating material for concrete surface treatment of the present invention is the main material is cement, since the amount of cement used is 40 to 60% by weight, hardening drying shrinkage rate can not be considered bar hardening dry by adding anhydrous gypsum or calcium carbonate powder The shrinkage rate was reduced, and the hardening shrinkage rate was reduced to 1% or less by using 4 to 10% by weight of anhydrous gypsum or calcium carbonate powder.
무수석고 또는 탄산칼슘 분말의 사용량이 4% 미만일 경우에는 경화건조수축율이 높아져 균열, 들뜸 현상이 발생하는 단점이 있고, 10중량%를 초과할 경우에는 첨가 상승 효과가 미약하여 경제적이지 못하였다.When the amount of anhydrous gypsum or calcium carbonate powder is less than 4%, there is a disadvantage in that the hardening shrinkage rate is increased, so that cracking and lifting occurs, and when it exceeds 10% by weight, the synergistic effect of addition is weak and economical.
한편, 콘크리트면과의 접착력을 향상시키고 표면강도를 향상시키기 위하여 시멘트 혼화용 프리마 디스퍼죤을 사용하는 데 본 발명에서는 콘크리트가 알카리성이기 때문에 내알카리성인 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지를 사용하였다. 특히, 에틸렌 초산 비닐계 재유화형 분말 수지가 효과적이었다.On the other hand, in order to improve the adhesion to the concrete surface and to improve the surface strength, the cement admixture Prima disperzone is used in the present invention because the alkali is alkali-resistant acrylic, vinyl acetate, ethylene vinyl acetate or synthetic rubber system Remulsification type powder resin of was used. In particular, ethylene vinyl acetate type remulsifying powder resin was effective.
콘크리면과의 부착강도는 10kgf/㎠ 이상이 되어야 들뜸 현상을 방지할 수 있는 것으로 알려져 있기 때문에 본 발명에서는 분말 수지의 배합을 전고형분이 4 ∼ 5%로 하여 부착강도가 13kgf/㎠가 되도록 하였다.Since it is known that the adhesion strength to the concrete surface should be 10 kgf / cm 2 or more to prevent the lifting phenomenon, in the present invention, the blending of the powder resin was 4 to 5% so that the adhesion strength was 13 kgf / cm 2. .
상기와 같이 본 발명에서는 재유화형 분말 수지를 사용하여 접착강도 향상과 무기질 재료의 유연성을 주었으며, 무수석고 또는 탄산칼슘 분말 첨가로 시멘트 경화건조수축율을 감소시켜 균열, 들뜸 현상을 방지하고 표면강도를 증진시켜 표면을 매끄럽게 마감하여 마감성을 향상시켰다.As described above, in the present invention, re-emulsified powder resin is used to improve adhesion strength and flexibility of inorganic materials, and by adding anhydrous gypsum or calcium carbonate powder to reduce cement hardening drying shrinkage rate to prevent cracking, lifting, and surface strength. The surface is smoothed to improve the finish.
또한, 본 발명의 시멘트계 콘크리트 면처리용 바탕조정 도장재는 초기 건조로 인한 문제와 에어분사식 장비에 따른 초기건조문제를 해소하기 위하여 증점보수제를 첨가하여 콘크리트 바탕면에 분사되어 경화가 시작되는 시간이 20분 내외가 되도록 하였다.In addition, the ground-adjusting coating material for cement-based concrete surface treatment of the present invention is sprayed on the concrete surface by adding a thickener in order to solve the problems caused by the initial drying and the initial drying problem according to the air spraying equipment is 20 hours to start curing Minutes or less were allowed.
이는 콘크리트 바탕면에 분사되어진 후 20분 내외에 마감작업이 이루어지기 때문이다.This is because the finishing work is performed within about 20 minutes after being sprayed on the concrete base surface.
소포제는 도장재의 분사시 또는 재료들의 혼합시에 생성될 수도 있는 기포를 제거하기 위한 것이고, 섬유질 혼화제는 제조되는 도장재의 접착강도를 더욱 향상시키기 위한 것이다.Defoamers are intended to remove bubbles that may be generated upon spraying the coating material or upon mixing of the materials, and the fibrous admixture is to further improve the adhesive strength of the coating material to be produced.
증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 섬유질 혼화제 0.2 ∼ 0.3중량%를 사용하는 것이 효과 발현과 경제적인 측면에서 가장 바람직하였지만 반복실험을 통하여 사용량을 변경할 수 있다.Although the use of thickening agent 0.2 to 0.3% by weight, dispersant 0.1 to 0.2% by weight, antifoaming agent 0.1 to 0.2% by weight, and fiber admixture 0.2 to 0.3% by weight were most preferable in terms of effect expression and economics, the amount of use could be changed through repeated experiments. have.
증점제, 분산제, 소포제, 섬유질 혼화제는 본 발명이 속하는 기술 분야에서 통상적으로 사용되는 것이라면 어떠한 것을 사용하여도 가능하지만 이 역시 반복 실험을 통하여 특히 적합한 것을 선정할 수 있다.Thickeners, dispersants, antifoaming agents, fibrous admixtures may be used as long as they are commonly used in the art to which the present invention belongs, but this may also be selected particularly suitable through repeated experiments.
다음의 실시예는 본 발명을 좀 더 구체적으로 설명하는 것이지만, 본 발명의 범주를 한정하는 것은 아니다.The following examples illustrate the invention in more detail, but do not limit the scope of the invention.
