More particularly, the present invention relates to a waterproofing agent for polyurea film, (2-hydroxyethyl) ethyldiamine, methylene bis N, N dibutyl aniline, diphenyl methanediamine, 1,2 bis (2-hydroxyethyl) -Amino-phenylthioethane), tetramethylbutanediamine, dimethyltoluenediamine, dimethylcyclohexylamine, an inorganic pigment silicate, and an organic pigment phthalocyanine are mixed to prepare a polyurea B liquid, B liquid at a predetermined volume ratio to produce a flame retardant polyurethane coating film waterproofing agent and a waterproofing 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 처리는 일반적으로 방수용 수지를 콘크리트 구조물의 표면에 도포함으로서 이루어진다.In order to prevent corrosion or damage caused by moisture of concrete structure, it is required to waterproof or treat the surface of concrete structure. Such waterproofing treatment is generally performed by applying a waterproof resin to the surface of a concrete structure.

종래 일반적인 콘크리트 구조물 표면의 방수 공법은, 등록특허 10-1215403호 등에 개시된 바와 같이, 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.A conventional waterproofing method for a concrete structure surface includes a pretreatment step of removing contaminants on the surface of a waterproofing structure and planarizing the surface of the waterproofing structure as disclosed in Japanese Patent Application No. 10-1215403 and the like, And applying polyurea on the primer layer.

이러한 폴리우레아의 분자는 보통의 경우 유연성을 크게 하는 요소와 경도를 크게 하는 요소들이 고르게 분포되어 있는 상태로 구성되어 있다.These molecules of polyurea usually consist of an element that increases the flexibility and an element that increases the hardness evenly.

일반적으로 알려진 바에 의하면, 유연성을 크게 하는 요소는 낮은 유리전이온도를 갖는 것으로 폴리에테르, 폴리에스테르, 폴리알킬디올 등으로 중량 평균분자량이 400-5000 사이일 때 유연성이 커지고, 경도를 크게 하려면 높은 Tg를 갖고 있으며 준결정성의 방향족 디이소시아네이트가 낮은 분자량의 사슬 확장자에 결합하면 경도가 커진다.It is generally known that a material having a high flexibility is a material having a low glass transition temperature. The polyether, polyester and polyalkyldiol have a high flexibility when the weight average molecular weight is between 400 and 5,000, and a high Tg And when the semi-crystalline aromatic diisocyanate is bonded to a chain extension of low molecular weight, 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.Generally, polyureas are synthesized with diamines having chain extensions and low molecular weight to form urea units. Therefore, the polyurea exhibits a wide variety of properties depending on various factors such as the selected substance, the molecular weight, or the reacted ratio. That is, it is possible to change from a substance whose property is fragile to a substance which is hard or soft, and which is of a certain viscosity. Particularly, in the case of polyurea, since the amide ester bond of fatty acid has a mixed bond, the property at high temperature has an intermediate property between these polyester and polyamide.

폴리우레아의 합성은 부가반응과 축합반응의 두 개의 큰 영역으로 구분할 수 있다. 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.The synthesis of polyurea can be divided into two large regions, an addition reaction and a condensation reaction. The addition reaction occurs when the unsaturated monomer reacts in the reaction initiation step, the development step, and the termination step. Usually, monomers are simple molecules with a double bond, which reacts rapidly in the initiation step, breaking one of the two double bonds, until the unreacted monomer is almost lean.

대부분의 경우 부가반응은 부생산물을 만들지 않고 진행된다. 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.In most cases, the addition reaction proceeds without making the byproduct. Condensation or staged growth reactions occur when monomers react with molecules with double functional groups at the stage where they were made to form chains of macromolecules. This is similar to the condensation reaction between molecules with small molecular weights. At this time, small molecules such as water and carbon dioxide are removed.

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. 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.Addition reaction can be classified into homogeneous polymer or copolymer. The fine form of copolymer can be divided into random, cross, and lump form, but it differs depending on reaction conditions, concentration, reactivity ratio of monomers. Furthermore, controlling the molecular weight or the distribution of molecular weight after the reaction of the final reaction product polymer is more difficult than the condensation reaction which is controlled by using a reagent which changes the chain form. Control of the reactivity can be controlled by anionic polymerisation and in some cases it is possible to synthesize a nearly single-chain distribution. The condensation reaction is also used to make copolymeric polymer materials. The monomers having a double functional group are used to form a chain polymer, and those having three or more functional groups may constitute a crosslinked polymer network in a three-dimensional space.

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 진행한다. 그리고 폴리우레아는 합성고무와 같은 엘라스토머 성질을 가지므로 화재에 취약한 문제점을 가지고 있다. Polyurea is a polymer material having an elastomeric property formed by the reaction of a polyoxyether polyamine mixture having a functional group with an isocyanate prepolymer. Because of the rapid reactivity of amines and isocyanates, polyurea can not be used in general at room temperature. Proceed with the operation. And polyurea has an elastomeric property such as synthetic rubber, and thus has a problem of being vulnerable to fire.
