Description

폴리우레아계 도막 방수재 및 이를 이용한 방수공법{polyurea membrane waterproofing agent and construction method for waterproofing using this}Polyurea membrane waterproofing agent and construction method for waterproofing using this}

본 발명은 폴리우레아계 도막 방수재 및 이를 이용한 방수공법에 관한 것으로, 자세하게는 불소알콜을 폴리머 분자 내에 도입하여 최종적으로 완결되는 폴리우레아의 내오염성을 개선하여 물성 저하가 발생 되지 않도록 한 폴리우레아 도막방수재 및 이를 이용한 방수공법에 관한 것이다.
The present invention relates to a polyurea-based coating waterproofing material and a waterproofing method using the same. Specifically, the polyurea coating waterproofing material is introduced by introducing fluorine alcohol into a polymer molecule to improve the fouling resistance of the finally completed polyurea so that no deterioration in physical properties occurs. And it relates to a waterproof method using the same.

콘크리트 구조물의 수분에 의한 부식이나 파손 등을 방지하기 위해서는 콘크리트 구조물 표면에 방수 또는 방식 처리를 하는 것이 요구된다. 이러한 방수 또는 방식 처리를 위해 일반적으로 방수용 수지를 콘크리트 구조물의 표면에 도포하게 된다.In order to prevent corrosion or damage due to moisture of the concrete structure, it is required to waterproof or anticorrosive treatment on the surface of the concrete structure. For such waterproofing or anticorrosive treatment, waterproofing resin is generally applied to the surface of the concrete structure.

종래 일반적인 콘크리트 구조물 표면의 방수 공법은 방수하고자 하는 구조물의 표면에 묻은 오염물을 제거하고 평탄화하는 전처리 단계와, 상기 전처리된 표면에 프라이머를 코팅하여 프라이머층을 형성하는 단계 및 상기 프라이머층 상에 폴리우레아를 도포하는 단계를 포함하여 이루어진다. 이러한 폴리우레아의 분자는 보통의 경우 유연성을 크게 하는 요소와 경도를 크게 하는 요소들이 고르게 분포되어 있는 상태로 구성되어 있다. 유연성을 크게 하는 요소는 낮은 유리전이온도(Tg)를 갖는 것으로 폴리에테르, 폴리에스테르, 폴리알킬디올 등으로 중량 평균분자량이 400 ~ 5000 사이일 때 유연성이 커지고, 경도를 크게 하려면 높은 유리전이온도(Tg)를 갖고 있으며 준결정성의 방향족 디이소시아네이트가 낮은 분자량의 사슬 확장자에 결합하면 경도가 커진다.
The conventional waterproof method of the surface of the concrete structure is a pre-treatment step of removing and planarizing contaminants on the surface of the structure to be waterproofed, forming a primer layer by coating a primer on the pre-treated surface and a polyurea on the primer layer It comprises a step of applying. Such molecules of polyurea are usually composed of evenly distributed elements that increase flexibility and those that increase hardness. The factors that increase flexibility have a low glass transition temperature (Tg). Polyether, polyester, polyalkyldiol, etc. are used to increase flexibility when the weight average molecular weight is between 400 and 5000, and to increase hardness, high glass transition temperature ( Tg) and when the semi-crystalline aromatic diisocyanate binds to a low molecular weight chain extension, the hardness becomes large.

일반적으로 폴리우레아는 사슬 확장자와 낮은 분자량을 갖는 디아민류와 합성되어 우레아 단위체를 만드는 것이다. 따라서 폴리우레아는 선택된 물질이나 분자량, 또는 반응되는 비율 등의 기타 다양한 요소에 의하여 그 성질이 폭 넓게 변화되어 나타난다. 즉, 그 성질이 부스러지기 쉬운 물질에서 단단한 물질 또는 부드러운 물질, 더 나아가서는 어떤 점성을 갖는 물질로 변화가 가능하다. 특히, 폴리우레아의 경우에는 지방산의 아미드 에스테르 결합이 혼합된 결합을 가지므로 고온에서의 성질은 이들 폴리에스테르계와 폴리아미드계의 중간적 성질을 가지고 있다.
In general, polyurea is synthesized with diamines having chain extension and low molecular weight to form urea units. Therefore, polyurea is widely changed in its properties by various materials such as selected material, molecular weight, or reaction rate. In other words, it is possible to change the material from a brittle material to a hard material or a soft material, or even a material having a certain viscosity. In particular, in the case of polyurea, since the amide ester linkages of fatty acids have mixed bonds, the properties at high temperatures have intermediate properties between these polyester and polyamides.

폴리우레아의 합성은 부가반응과 축합반응의 두 개의 큰 영역으로 구분할 수 있다. The synthesis of polyurea can be divided into two large domains: addition and condensation.

부가반응은 불포화 단량체가 반응 개시 단계, 전개 단계, 종결 단계에서 반응하여 일어난다. 보통 단량체들은 이중결합을 가지고 있는 간단한 분자들인데 개시단계에서 두 개의 이중결합 중 하나가 깨지면서 반응 하는데 미반응 단량체가 거의 희박할 때까지 빠르게 반응이 진행된다. 대부분의 경우 부가반응은 부생산물을 만들지 않고 진행된다. Addition reactions occur when unsaturated monomers react at the initiation, development and termination of the reaction. Normally, monomers are simple molecules with double bonds. At the start, one of the two double bonds is broken and reacts quickly until the unreacted monomer is almost lean. In most cases, the addition reaction proceeds without producing byproducts.

축합 또는 단계적 성장 반응은 단량체들이 고분자의 사슬을 형성하기 위해 만들어진 단계에서 이중 작용기를 갖는 분자와 반응할 때 일어난다. 이는 작은 분자량을 갖는 분자들 간의 축합반응과 유사하다. 이때 작은 분자인 물이나 이산화탄소 같은 물질은 제거되기도 한다.Condensation or step growth reactions occur when monomers react with molecules with double functional groups at the stages made to form the polymer's chains. This is similar to the condensation reaction between molecules of small molecular weight. At this time, small molecules such as water and carbon dioxide may be removed.

한편, 부가반응은 균일 고분자나 공중합체로 구분할 수 있는데, 공중합체의 미세한 형태는 무작위, 교차, 덩어리 형태로 나눌 수 있지만 이는 반응 조건이나 농도, 단량체의 반응성 비율 등에 따라 차이가 있다. 더군다나 최종 반응 생성물인 고분자들의 반응 후 분자량이나 분자량의 분포 등을 제어하는 것은 사슬 형태를 변화시키는 시약을 사용하여 제어하는 축합반응보다도 더 어려운 것이다. 반응성의 조절은 음이온 고분자화법에 의해 조절될 수 있고 어떤 경우에는 거의 단일 연쇄상 분포의 합성도 가능하다. On the other hand, the addition reaction can be classified into a homogeneous polymer or copolymer, the fine form of the copolymer can be divided into random, cross, lump form, but this is different depending on the reaction conditions, concentration, monomer reactivity ratio. Furthermore, controlling the molecular weight or distribution of molecular weight after the reaction of the polymers as the final reaction product is more difficult than the condensation reaction controlled by using a reagent that changes the chain shape. The control of reactivity can be controlled by anionic polymerisation and in some cases the synthesis of nearly single chain distributions is also possible.

또한 축합반응은 공중합 고분자물질을 만들 때도 사용 된다. 이중 작용기를 갖는 단량체 들은 사슬형 고분자를 만들기 위해 이용되고 삼중 이상의 작용기를 갖는 것은 삼차원적 공간에 교차 결합 고분자 망을 구성할 수도 있다.
Condensation reactions are also used to make copolymerized polymers. Monomers having a double functional group are used to make a chain polymer, and having three or more functional groups may form a cross-linked polymer network in a three-dimensional space.

하지만 상기와 같은 폴리우레아는 관능기를 갖는 폴리옥시에테르 폴리아민 혼합물과 이소시아네이트 프리폴리머의 반응으로 형성되는 엘라스토머 특성을 갖는 고분자 물질로 아민과 이소시아네이트의 급속한 반응성 때문에 일반적으로 상온에서 혼합하여 사용할 수 없으며 특수한 스프레이 장비를 이용하여 도장작업을 진행해야만 한다.However, such polyurea is an elastomeric material formed by the reaction of a polyoxyether polyamine mixture having a functional group and an isocyanate prepolymer, and thus, due to the rapid reactivity of the amine and the isocyanate, it cannot generally be mixed at room temperature. The painting work should be done.

특히, 폴리우레아는 합성고무와 같은 엘라스토머 성질을 가지므로 콘크리트 구조물에 시공후 자외선 및 대기 오염 물질에 의하여 오염되어 물성히 급격히 저하되는 구조적 문제점을 가지고 있다.
In particular, since polyurea has the same elastomeric properties as synthetic rubber, it has a structural problem of being rapidly contaminated by ultraviolet rays and air pollutants after construction on concrete structures.

Preferred 2-methyl-1,5-pentamethylene diisocyanate according to the present invention exhibited the best physical properties using NCO% of 9-13.

상기 메톡시폴리에틸렌글리콜은 42.9 ~ 50.0 중량부를 벗어나면 1차 혼합물과 2차 혼합물의 반응비를 맞추기가 불가능하여 이와 같은 구간 수치가 가장 바람직하다. 본 발명에 따른 바람직한 메톡시폴리에틸렌글리콜은 수산기가가 80 ~ 150, 수분 0.04%이하 점도 300 ~ 500cps인 것을 사용하는 것이 가장 좋은 물성 효과를 나타내었다.
