Description

무기질계 분말 도장 마감재{Coating and finish-processing material using the inorganic compound powder as the main component}Coating and finish-processing material using the inorganic compound powder as the main component}

본 발명은 콘크리트로 형성된 면 뿐만아니라 콘크리트 블럭, ALC 블럭, PC 판넬, ALC 판넬, 아코텍 판넬로 형성된 바탕면을 도장 마감처리하는 데 사용될 수 있는 무기질계 분말 도장 마감재에 관한 것이다.The present invention relates to inorganic powder coating finishes that can be used to paint finishes formed from concrete as well as concrete blocks, ALC blocks, PC panels, ALC panels, and Acotech panels.

콘크리트를 사용하여 축조되고 있는 대부분의 건축물은 건축물의 외관을 미려하게 하고 방수, 방음 효과를 부여할 뿐만 아니라 건축물 자체를 보호하기 위하여 마감 도장을 행하고 있다.Most buildings that are constructed using concrete not only make the exterior of the building beautiful, provide waterproofing and soundproofing effect, but also finish coating to protect the building itself.

일반적으로 마감 도장은 도장 마감재로서 수성페인트, 유성페인트 등의 페인트를 주로 사용하여 행하여지고 있으나, 대부분의 바탕면은 무기질 재료로 형성되고 도장 마감재는 유기질 도료이기 때문에 많은 문제점들이 발생하고 있다.In general, the finish coating is mainly done using a paint such as water-based paint, oil paint, etc., but most of the base surface is formed of an inorganic material, and many problems occur because the coating finish is an organic paint.

예를 들어, 무기질 바탕면에 유기질 도료를 사용하여 마감 처리를 할 경우 바탕면과 유기질 도료와의 친화력이 떨어지고 장기적인 내구성이 저하되어 구조체의 거동에 의한 바탕면과의 들뜸 현상이 발생하는 단점이 있고, 구조체 균열에 따른 수분 침투가 발생하여 바탕면과 마감재와의 들뜸 현상이 심각하게 발생되는 등의 문제점이 있다.For example, when the finish is processed using organic paint on the inorganic base surface, the affinity between the base surface and the organic paint decreases and the long-term durability deteriorates, causing the phenomenon of lifting with the base surface due to the behavior of the structure. , There is a problem such that the moisture infiltration occurs due to the structure cracks and the lifting phenomenon between the base surface and the finish material is seriously generated.

즉, 유기질 도료를 사용하여 마감처리를 하는 종래의 방법에 있어서 바탕면의 균열 발생시 마감층에까지 균열이 발생하게 되고, 균열에 의하여 발생된 틈으로 수분이 침투하게 되며, 침투된 수분에 의한 바탕면의 수축 팽창에 따라 접착력 저하는 물론 들뜸 현상이 발생하게 되는 문제점이 있을 뿐만 아니라 유기질 도료를 사용하는 경우 3 ∼ 6회의 덧바름 시공을 행하여야 하므로 번거롭고, 경제적이지 못하며, 시공 기간이 오래 걸리는 등의 단점이 발생하게 된다.That is, in the conventional method of finishing using organic paints, when the base surface is cracked, cracks are generated up to the finishing layer, and moisture penetrates into the gap generated by the crack, and the base surface by the infiltrated moisture As a result of the contraction and expansion of the adhesive force, there is a problem of deterioration of the adhesive force as well as the lifting phenomenon, and when using organic paint, it is cumbersome, not economical, and it takes a long time to apply the organic coating. Disadvantages arise.

또한, 유기질 도료를 사용하여 마감 처리를 하고 재마감 처리를 행하여야 할 경우 유기질 도료와 다른 특성의 마감재에 의한 마감 처리가 어려워 1차 마감 처리시 사용하였던 도료와 같은 도료를 사용하여 마감하여야 하므로 마감재 선택의 폭이 좁아 수요자의 요구에 부응하기 어려운 문제점이 있다.In addition, in case of finishing and refinishing by using organic paint, it is difficult to finish by organic paint and other characteristic finishing materials, so it must be finished with the same paint used in the first finishing treatment. There is a problem that it is difficult to meet the needs of consumers because of the narrow choice.

그러나, 현재까지 도장 마감재로서 바탕면과 거의 특성이 동일한 무기질계 마감 도장재의 개발은 이루어진 바 없고, 균일한 품질을 갖는 제품의 개발은 물론 분사식으로 적용되기 위한 제품 역시 개발된 바 없다.However, until now, the development of an inorganic finish coating material having almost the same characteristics as the base surface as a coating finish has not been made, and a product for uniform application as well as a spray application has not been developed.

따라서, 본 발명의 목적은 분사식으로 바탕면 전체에 마감 도장을 할 수 있어 공정이 용이하고 경제적이며, 바탕면과 도장 마감재의 부착성을 향상시킴과 동시에 미려한 외관을 갖는 마감시공이 될 수 있도록 하는 무기질계 도장 마감재를 제공하는 데 있다.Therefore, the object of the present invention is to spray the entire surface of the base can be sprayed, easy to process and economical, to improve the adhesion of the base and the coating finish and at the same time to have a beautiful appearance appearance To provide an inorganic paint finish.

상기 목적을 달성하기 위하여 본 발명에서는 탄산칼슘계 분말 60 ∼ 89중량%, 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지 1 ∼ 30중량%, 포틀란트시멘트 10 ∼ 39중량%로 구성되는 주재료에 대하여 증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 무기질 안료 2 ∼ 10중량%로 구성되는 무기질계 분말 도장 마감재를 제조하고, 이를 분사식으로 도장하므로서 콘크리트면의 평활성을 향상시키고, 콘크리트면과 마감재의 부착성을 향상시킴과 동시에 양호한 마감시공이 될 수 있도록 하며, 종래의 공사가 현장에서 임의로 배합하여 사용함에 따른 제반 문제점들을 해결할 수 있고 품질 안정화를 확보할 수 있으며, 공사비를 절감할 수 있는 효과를 얻을 수 있었다.In order to achieve the above object, in the present invention, 60 to 89% by weight of calcium carbonate powder, 1 to 30% by weight of acryl-based, vinyl acetate-based, ethylene-vinyl acetate-based or synthetic rubber-based reemulsified powder resin, and 10 to 39 portland cement An inorganic powder coating finish made of 0.2 to 0.3 wt% thickener, 0.1 to 0.2 wt% dispersant, 0.1 to 0.2 wt% defoaming agent, and 2 to 10 wt% inorganic pigment was prepared, and sprayed on the main material composed of wt%. It improves the smoothness of concrete surface, improves the adhesion of concrete surface and finishing materials, and at the same time ensures good finish construction, and solves all the problems caused by conventionally mixing and using conventional construction on site. Quality stabilization can be secured and construction costs can be reduced.

본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

본 발명에 따른 무기질계 도장 마감재는 탄산칼슘계 분말 60 ∼ 89중량%, 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지 1 ∼ 30중량%, 포틀란트시멘트 10 ∼ 39중량%로 구성되는 주재료에 대하여 증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%, 무기질 안료 2 ∼ 10중량%로 구성되는 것으로 특징지워진다.The inorganic paint finish according to the present invention is 60 to 89% by weight of calcium carbonate powder, 1 to 30% by weight of acryl-based, vinyl acetate-based, ethylene-vinyl acetate-based or synthetic rubber-based reemulsified powder resin, 10-39 portland cement. It is characterized by being comprised from 0.2 to 0.3 weight% of a thickener, 0.1 to 0.2 weight% of a dispersing agent, 0.1 to 0.2 weight% of an antifoamer, and 2 to 10 weight% of an inorganic pigment with respect to the main material which consists of weight%.

탄산칼슘계 분말로는 입도 250메쉬를 갖는 방해석 분말과 입도 320메쉬를 갖는 방해석 분말을 50 : 50의 비율로 혼합하여 사용하였으며, 이는 입도분포도를 조정하여 도막층의 밀도를 높이고, 분사 두께가 1 ∼ 3mm 정도가 되어 분사시 흐름을 방지하기 위한 것이다.As a calcium carbonate powder, a calcite powder having a particle size of 250 mesh and a calcite powder having a particle size of 320 mesh were mixed at a ratio of 50:50, and this was adjusted by adjusting the particle size distribution to increase the density of the coating layer, and the spray thickness was 1. It is about 3mm in order to prevent the flow at the time of injection.

탄산칼슘계 분말로 방해석이 가장 효과적이지만 무수석고 또는 탄산칼슘 등과 같이 본 발명에서 얻고자 하는 효과를 저해하지 않는 것이라면 모두 사용이 가능하다.Although calcite is the most effective as calcium carbonate-based powder, any one can be used as long as it does not inhibit the effect to be obtained in the present invention such as anhydrous gypsum or calcium carbonate.

본 발명의 무기질계 도장 마감재는 시멘트를 사용하고 있고, 경화건조수축율을 고려하지 않을 수 없는 바, 탄산칼슘계 분말을 사용하여 경화건조수축율을 감소시켰으며, 탄산칼슘계 분말을 60 ∼ 89중량%를 사용하였다.As the inorganic paint finish of the present invention, cement is used, and the hardening shrinkage rate cannot be considered, and the hardening shrinkage rate is reduced by using calcium carbonate powder, and the calcium carbonate powder is 60 to 89% by weight. Was used.

탄산칼슘계 분말의 사용량이 60중량% 미만일 경우에는 상대적으로 시멘트의 사용량이 높아 경화건조 수축율이 높아져 균열, 들뜸 현상이 발생하거나 시멘트 성분 중 백화를 유발하는 성분이 유출될 염려가 있고 경우에 따라서는 백화 유발 성분이 유출되어 표면 색상이 변형되는 단점이 있고, 89중량%를 초과할 경우에는 첨가 상승 효과가 미약하여 경제적이지 못할 뿐만 아니라 시멘트의 사용량이 낮아 접착강도가 저하되는 문제점이 있었다.When the amount of calcium carbonate-based powder is less than 60% by weight, the amount of cement is relatively high, which increases the rate of hardening shrinkage, which may cause cracking, lifting, or leakage of cement-causing components. When the whitening-inducing component is leaked, the surface color is deformed, and when it exceeds 89% by weight, the synergistic effect of the addition is not so low that it is not economical, and there is a problem that the adhesive strength is lowered due to the low amount of cement.

시멘트는 제조되는 도장 마감재의 색상 발현을 저해하지 않는 백색 포틀란트 시멘트의 사용을 기준으로 하였으며, 시멘트의 사용량이 10중량% 미만일 경우에는 제조되는 도장 마감재의 접착력이 저하되는 문제점이 있고, 39중량%를 초과할 경우에는 경화건조수축율이 높아져 균열, 들뜸 현상이 발생하고 시멘트의 백화성분이 표면에 유출되어 색상을 변색시키는 단점이 있으며, 제조되는 도장 마감재의 압축강도는 80kgf/㎠ 이상이 되도록 하였다.Cement was based on the use of white portland cement that does not inhibit the color appearance of the paint finish to be produced, when the amount of the cement used is less than 10% by weight, there is a problem that the adhesive strength of the paint finish is produced, 39 weight When it exceeds%, the hardening shrinkage rate increases, causing cracking and lifting phenomenon, and the whitening component of cement spills on the surface, causing discoloration. The compressive strength of the paint finish produced is more than 80kgf / ㎠. .

한편, 콘크리트면과의 접착력을 향상시키고 표면강도를 향상시켜 표면의 긁힘현상을 방지하기 위하여 재유화형 분말 수지를 사용하였으며, 특히 본 발명에서는 콘크리트가 알카리성이기 때문에 내알카리성인 아크릴계, 초산비닐계, 에틸렌초산비닐계 또는 합성고무계의 재유화형 분말 수지를 사용하였다. 가장 바람직하게는 에틸렌 초산 비닐계 재유화형 분말 수지가 효과적이었다.On the other hand, re-emulsified powder resin was used to improve the adhesion to the concrete surface and to improve the surface strength to prevent the surface scratching, especially in the present invention, because the concrete is alkali-based acrylic, vinyl acetate, ethylene Vinyl acetate-based or synthetic rubber-based reemulsified powder resins were used. Most preferably ethylene vinyl acetate based reemulsified powder resins were effective.

콘크리면과의 부착강도가 높아야 들뜸 현상을 방지할 수 있는 것으로 알려져 있기 때문에 본 발명에서는 분말 수지의 배합을 전고형분이 1 ∼ 30%로 하여 부착강도가 6kgf/㎠ 이상이 되도록 하였다(KSL 1593 타일 접착제 접착 강도 기준).Since it is known that the adhesion strength to the concrete surface can be prevented to prevent the floating phenomenon, in the present invention, the total resin content is 1 to 30%, so that the adhesion strength is 6 kgf / cm 2 or more (KSL 1593 tile). Based on adhesive adhesive strength).

상기와 같이 본 발명에서는 재유화형 분말 수지를 사용하여 접착강도 향상과 무기질 재료의 유연성을 주었으며, 콘크리트면과 마감층과의 친화력 향상으로 일체감을 주어 균열과 들뜸을 방지하고 장기적인 내구성을 갖도록 하였고, 탄산칼슘계 분말 사용으로 시멘트 경화건조수축율을 감소시켜 들뜸을 방지하고 표면강도를 증진시켜 표면을 매끄럽게 마감하여 마감성을 향상시켰다.As described above, in the present invention, re-emulsification powder resin is used to give adhesion strength and flexibility of inorganic materials, and to give a sense of unity by improving affinity between the concrete surface and the finishing layer to prevent cracking and lifting and to have long-term durability, and carbonic acid. The use of calcium-based powder reduces cement hardening drying shrinkage, prevents lifting, and improves the surface strength to improve the finish by smoothly finishing the surface.

또한, 본 발명의 무기질계 분말 도장 마감재는 에어분사식 시공에 따른 초기건조 문제를 해소하기 위하여 증점보수제를 첨가하여 콘크리트 바탕면에 분사되어 경화가 시작되는 시간인 오픈 타임이 20분 내외가 되도록 하여 충분한 경화와 양생이 이루어지도록 하였다.In addition, the inorganic powder coating finish of the present invention is added to a thickening agent in order to solve the initial drying problems caused by the air spraying construction is sprayed on the concrete base surface so that the open time, which is the time when the curing starts within 20 minutes is sufficient Curing and curing were achieved.

이는 콘크리트 바탕면에 분사된 후 초기 건조가 이루어지면 경화가 되지 않고 강도가 저하되어 도장 마감재로서의 가치를 상실하기 때문이다.This is because the initial drying after spraying on the concrete base surface is not cured, the strength is lowered and loses the value as a coating finish.

소포제는 도장 마감재의 분사시 또는 재료들의 혼합시에 생성될 수도 있는 기포로 인한 접착강도 저하 등의 문제점을 해결하기 위한 것이다.Defoamers are intended to solve problems such as a decrease in adhesive strength due to bubbles that may be generated during spraying of paint finishes or mixing of materials.

증점제 0.2 ∼ 0.3중량%, 분산제 0.1 ∼ 0.2중량%, 소포제 0.1 ∼ 0.2중량%를 사용하는 것이 효과 발현과 경제적인 측면에서 가장 바람직하였지만 반복실험을 통하여 사용량을 변경할 수 있다.Although the use of thickener 0.2 to 0.3% by weight, dispersant 0.1 to 0.2% by weight, and antifoaming agent 0.1 to 0.2% by weight was most preferred in terms of effect expression and economics, the amount of use may be changed through repeated experiments.

증점제, 분산제, 소포제는 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, defoamers can be used as long as they are commonly used in the art to which the present invention belongs, but this can also be selected particularly suitable through repeated experiments.

한편, 제조되는 도장 마감재의 색상을 발현시키기 위하여 첨가되는 안료는 반드시 무기질계 안료를 사용하여 나머지 원료들과의 친화력을 향상시키고, 바탕면과의 접착력이 향상되도록 하며, 목적하는 색상 및 선명도에 따라 반복 실험을 통하여 적절히 조합하여 사용할 수 있고, 2 ∼ 10중량%를 사용하는 것이 효과적이다.On the other hand, the pigment added to express the color of the paint finish is produced by using inorganic pigments to improve the affinity with the rest of the raw materials, to improve the adhesion to the base surface, depending on the desired color and clarity It can be used in combination suitably through repeated experiments, and it is effective to use 2-10 weight%.

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.
