Description
본 발명은 건설 재료분야에 관한 것으로서, 상세하게는 무기질 결합재 및 이를 이용한 액상 폴리머 조성물에 관한 것이다.The present invention relates to the field of construction materials, and more specifically to inorganic binders and liquid polymer compositions using the same.
현재 세계는 지구온난화에 대한 대처 방안으로서, 이산화탄소 감축이 가장 중요한 방안으로 추진되고 있다.Currently, the world is promoting carbon dioxide reduction as the most important measure to combat global warming.
이에 시멘트 산업의 경우도 기존 시멘트 대비 이산화탄소 발생량을 최대 70% 까지 감축시킬 수 있는 이산화탄소 반응경화형 시멘트인 칼슘-실리케이트 시멘트 클링커(CSC)(특허공개 10-2022-0097663) 등을 개발하여 대처해 나가고 있으며, 이의 활용방안에 대한 연구도 활발히 진행 중에 있다.Accordingly, the cement industry is responding by developing calcium-silicate cement clinker (CSC), a carbon dioxide reaction hardening type cement that can reduce carbon dioxide emissions by up to 70% compared to existing cement (Patent Publication No. 10-2022-0097663). , research on how to utilize it is also actively underway.
CSC 시멘트는 반응 시 이산화탄소를 필요로 하기 때문에, 양생기 내에 이산화탄소 분위기 조건을 쉽게 만들 수 있는 벽돌, 블록, 프리캐스팅 콘크리드와 같은 공장생산 제품에 대하여 용이하게 적용할 수 있는 장점이 있다.Since CSC cement requires carbon dioxide for reaction, it has the advantage of being easily applied to factory-produced products such as bricks, blocks, and precast concrete that can easily create carbon dioxide atmosphere conditions within the curing period.
이에 반해, 기존 시멘트에 비해 초기 강도발현에 필요한 C3S 및 C2S 함량이 적고 CO2와 반응하는 CS 및 C3S2의 함량이 높은 CSC 시멘트의 경우 현장 타설제품에 적용하기 어렵다는 문제점이 있다. On the other hand, in the case of CSC cement, which has a lower content of C 3 S and C 2 S required for initial strength development compared to existing cement and a high content of CS and C 3 S 2 that react with CO 2 , the problem is that it is difficult to apply to cast-in-place products. there is.

CSC의 함량이 80 중량%를 초과하면 초기의 강도발현 특성이 부족하고, 20 중량% 미만으로 하면 장기적인 이산화탄소 반응에 대한 효과가 미미하다. If the CSC content exceeds 80% by weight, the initial strength development characteristics are insufficient, and if the CSC content is less than 20% by weight, the effect on the long-term carbon dioxide reaction is minimal.

In the case of an antifoaming agent, if it is less than the above range, pinholes will be generated on the surface of the coating material, making it difficult to create a beautiful surface, and if it is more than the above range, the cost will be high compared to the effectiveness, making it uneconomical.

본 발명에 의한 액상 폴리머 조성물은, 위 분체 조성물 100 중량부; 유기 폴리머 5~20 중량부; 물 15~35 중량부;를 포함하여 구성된다.The liquid polymer composition according to the present invention includes 100 parts by weight of the above powder composition; 5 to 20 parts by weight of organic polymer; It consists of 15 to 35 parts by weight of water.
유기 폴리머는 부착 및 내구성 개선을 위해 사용되며, 아크릴계, 스타이렌-아크릴계, 비닐아세테이트 에틸렌(VAE)계, 폴리비닐 아세테이트(PVA)계, 스타이렌-부타디엔 수지(SBR)계 폴리머 중 하나 또는 2 이상의 혼합에 의해 형성된다.Organic polymers are used to improve adhesion and durability, and are one or more of acrylic, styrene-acrylic, vinyl acetate ethylene (VAE), polyvinyl acetate (PVA), and styrene-butadiene resin (SBR) polymers.

상기 범위 미만이면 폴리머 첨가 효과가 미미하여 표면경도 및 내구성이 저하되고, 상기 범위를 초과하면 유기물에 의한 초기 수화반응 억제에 따른 물성발현이 어렵게 된다.If it is less than the above range, the effect of adding polymer is insignificant, resulting in a decrease in surface hardness and durability, and if it exceeds the above range, it becomes difficult to develop physical properties due to inhibition of the initial hydration reaction by organic substances.
본 발명은 이산화탄소 반응경화형 시멘트인 칼슘-실리케이트 시멘트 클링커 (CSC)를 활용한 것으로서, 내염성을 갖는 속경형 유무기 복합 코팅재 조성물로 사용될 수 있다.The present invention utilizes calcium-silicate cement clinker (CSC), a carbon dioxide reaction hardening cement, and can be used as a fast-curing organic-inorganic composite coating composition with salt resistance.
본 발명의 핵심은 속경성을 발현하는 주요 수화물인 에트린자이트를 수화반응 초기에 효과적으로 생성시키는 것(화학식 1)과, CSC시멘트가 공기중의 이산화탄소와 탄산화반응을 통하여 장기적인 결정성장에 의해 장기물성을 증진시키는 것(화학식 2)에 있다. The core of the present invention is to effectively generate ettringite, the main hydrate that exhibits rapid hardening, at the beginning of the hydration reaction (Formula 1), and to create long-term crystal growth through carbonation reaction with carbon dioxide in the air. The goal is to improve physical properties (Formula 2).

[화학식 1][Formula 1]

이하, 본 발명에 의한 조성물의 물성을 입증하기 위한 실험내용 및 결과에 관하여 설명한다.Hereinafter, the details and results of experiments to prove the physical properties of the composition according to the present invention will be described.
표 1은 본 발명의 실시예 1 내지 3과, 비교예 1의 성분 및 배합에 관한 표이다.Table 1 is a table of ingredients and formulations of Examples 1 to 3 and Comparative Example 1 of the present invention.
본 발명의 실시예 1 내지 3은 속경성 시멘트를 사용한 배합 중 CSC 함량을 다양하게 변화시킨 것으로서, CSC 함량이 증가할수록 반응성을 보상하기 위하여 속경성 결합재(CAC, CSA)의 배합조건을 변형하여 제시한 것이다.Examples 1 to 3 of the present invention vary the CSC content during mixing using fast-setting cement, and the mixing conditions of the fast-setting binder (CAC, CSA) are modified to compensate for the reactivity as the CSC content increases. It was done.
비교예는 속경성시멘트를 사용하지 않고, 무기질 결합재 전량을 CSC 시멘트로 사용한 것이다.In the comparative example, fast-hardening cement was not used, and all of the inorganic binder was used as CSC cement.
C%는 무기질 결합재(시멘트) 100 중량%를 기준으로 한 배합비를 나타낸 것이고, T%는 분체 조성물(분말) 100 중량%를 기준으로 한 배합비를 나타낸 것이다.C% represents the mixing ratio based on 100% by weight of the inorganic binder (cement), and T% represents the mixing ratio based on 100% by weight of the powder composition (powder).
실험은 상대습도 60%, 표준온도 20℃의 조건에서 진행하였다.The experiment was conducted under conditions of 60% relative humidity and standard temperature of 20°C.
표 2는 본 발명의 실시예 1 내지 3과, 비교예 1에 관하여, 각 재령에 따라 각종 물성을 실험한 결과를 나타낸 것이다.Table 2 shows the results of testing various physical properties at different ages for Examples 1 to 3 and Comparative Example 1 of the present invention.
본 발명의 실시예 1 내지 3과 같이 무기질 결합재 중 속경성 재료가 혼합된 코팅재의 경우에는 초기 반응이 잘 진행되어 물성 발현이 양호하나, 비교예 1과 같이 CSC를 전량 무기결합재로 사용한 경우에는 재령 28일에 이르기까지 물성이 제대로 발현되지 않는 것을 알 수 있다.In the case of a coating material mixed with a fast-hardening material among the inorganic binders, as in Examples 1 to 3 of the present invention, the initial reaction proceeds well and the physical properties are good, but when CSC is used entirely as an inorganic binder, as in Comparative Example 1, the lifespan is delayed. It can be seen that the physical properties are not properly expressed until the 28th day.
56일의 장기 재령에 있어서는, CSC가 많이 혼입된 배합일수록 장기물성의 발현이 크게 증가하는 것으로 나타났는데, 이는 CSC 시멘트가 장기적으로 공기 중의 이산화탄소와 탄산화 반응을 일으킴에 기인하는 것으로 추정된다. In the long-term aging of 56 days, the expression of long-term properties increased significantly as the mix contained more CSC. This is believed to be due to the long-term carbonation reaction of CSC cement with carbon dioxide in the air.
비교예 1의 경우 56일 재령에서 일부 장기물성의 발현이 진행되나, 속경성 결합재가 들어간 본 발명의 실시예에 비해 현저히 떨어짐을 알 수 있다.In the case of Comparative Example 1, some long-term properties were developed at 56 days of age, but it was found to be significantly inferior to the example of the present invention containing a fast-hardening binder.
본 발명에 의한 조성물은 이산화탄소와의 탄산화 반응에 의해 장기물성의 증대효과를 얻을 수 있으면서도, 속경성 재료의 혼입에 의해 초기 물성 발현 또한 우수하다는 특징을 갖는다.The composition according to the present invention has the characteristic of being able to obtain an effect of increasing long-term physical properties through a carbonation reaction with carbon dioxide, and also having excellent initial physical properties due to the incorporation of fast-hardening materials.
따라서 염해의 우려가 큰 지역(해안가)에 설치된 구조물의 노출면에 도포하여 보호 및 보수가 가능하도록 하는 내염성 코팅재로 사용될 수 있으며, 제설제에 의해 손상된 도로포장 구조물 등에 대하여도 효과적으로 사용될 수 있다.Therefore, it can be used as a salt-resistant coating to enable protection and repair by applying it to the exposed surfaces of structures installed in areas with a high risk of salt damage (coastals), and it can also be effectively used on road pavement structures damaged by snow removal agents.
이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since the above is only a description of some of the preferred embodiments that can be implemented by the present invention, as is well known, the scope of the present invention should not be construed as limited to the above embodiments, and the scope of the present invention described above Both the technical idea and the technical idea underlying it will be said to be included in the scope of the present invention.
