Description
본 발명은 폴리우레아 도막 방수제에 관한 것으로서, 보다 상세하게는 디올레일토코페릴메틸실란올과 쇼듐락테이트메틸실란올을 폴리머 분재 내에 도입하여 최종적으로 완결되는 폴리우레아의 내구성을 개선하여 물성 저하가 발생되지 않도록 할 수 있는 폴리우레아 도막 방수제, 그 제조방법 및 그 방수제를 이용한 방수,방식 공법에 관한 것이다. The present invention relates to a waterproofing agent for polyurea coatings, and more particularly, to a waterproofing agent for polyurea coatings, and more particularly, to a waterproofing agent for polyurea coatings, A waterproofing method using the waterproofing agent, and a method for manufacturing the polyurea coating film.
일반적으로, 콘크리트 구조물의 수분에 의한 부식이나 파손 등을 방지하기 위해서는 콘크리트 구조물 표면에 코팅 처리를 하는 것이 요구된다. 이러한 코팅 처리는 일반적으로 고분자 수지를 콘크리트 구조물의 표면에 도포함으로써 이루어진다.Generally, in order to prevent corrosion or breakage of the concrete structure due to moisture, it is required to coat the surface of the concrete structure. This coating treatment is generally performed by applying a polymer resin to the surface of the concrete structure.
종래 일반적인 콘크리트 구조물 표면의 도막 공법은, 등록특허 10-1024534호 등에 개시된 바와 같이, 구조물의 표면에 묻은 오염물을 제거하고 평탄화하는 전처리 단계와, 상기 전처리된 표면에 프라이머를 코팅하여 프라이머층을 형성하는 단계와, 상기 프라이머층 상에 폴리우레아를 도포하는 단계를 포함하고 있다. Conventionally, a coating method on a surface of a concrete structure includes a pretreatment step of removing contaminants on the surface of a structure and planarizing the surface of the structure, as disclosed in Japanese Patent No. 10-104545, and a method of coating a primer layer on the pretreated surface to form a primer layer And applying the polyurea on the primer layer.
이 중, 상기 폴리우레아는, 그 분자가 보통의 경우 유연성을 크게 하는 요소와 경도를 크게 하는 요소들이 고르게 분포되어 있는 상태로 구성된다. Among them, the polyurea is constituted in such a state that an element which increases the flexibility and an element which increases the hardness are evenly distributed in the molecule.
여기서, 상기 폴리우레아에 있어서, 일반적으로 알려진 바에 의하면, 유연성을 크게 하는 요소는 낮은 유리전이온도(Tg)를 갖는 폴리에테르, 폴리에스테르, 폴리알킬디올 등이 400 내지 5000 사이의 중량평균분자량(Weight Average Molecular Weight)일 때 이고, 경도를 크게 하는 요소는 높은 유리전이온도를 가지는 준결정성의 방향족 디이소시아네이트가 낮은 분자량의 사슬 확장자에 결합될 때 이다. In the polyurea, it is generally known that a polyether, a polyester, a polyalkyldiol or the like having a low glass transition temperature (Tg) has a weight average molecular weight (Weight Average Molecular Weight), and a factor that increases the hardness is when a quasi-crystalline aromatic diisocyanate with a high glass transition temperature is bonded to a low molecular weight chain extender.
일반적으로 폴리우레아는, 사슬 확장자와 낮은 분자량을 가지는 디아민류와 합성되어 우레아 단위체를 만드는 것으로, 선택된 물질이나 분자량, 또는 반응 비율 등의 다양한 요소에 의해 그 성질이 폭 넓게 변화되어 나타나는데, 다시 말해서, 그 성질이 부스러지기 쉬운 물질에서 단단한 물질 또는 부드러운 물질, 더 나아가서는 어떤 점성을 가지는 물질로의 변화가 가능하고, 특히 지방산의 아미드 에스테르가 혼합된 결합을 가지므로 고온에서의 성질은 폴리에스테르계와 폴리아미드계의 중간적 성질을 가진다.In general, polyurea is synthesized with a chain extension and a diamine having a low molecular weight to form a urea unit, and its properties are widely varied depending on various factors such as a selected substance, molecular weight, or reaction ratio. In other words, It is possible to change from a substance which is susceptible to breakage to a substance which has a hard or soft substance and further to a substance having a certain viscosity, and in particular, the amide ester of a fatty acid has a mixed bond, It has an intermediate property of polyamide system.
이러한 폴리우레아의 합성은 부가반응과 축합반응의 두 개의 큰 영역으로 구분된다. 여기서, 상기 부가반응은 불포화 단량체가 개시단계, 전개단계, 종결단계에서 반응하여 발생되고, 이때, 보통 단량체들은 이중 결합을 가지고 있는 간단한 분자들인데 개시단계에서 두 개의 이중 결합 중 하나가 깨지면서 반응하는데, 미반응 단량체가 거의 희박할 때까지 빠르게 반응이 진행되며, 대부분의 경우 부가반응은 부생산물을 만들지 않고 진행된다. 상기 축합반응(또는 단계적 성장 반응)은 단량체들이 고분자의 사슬을 형성하기 위해 만들어진 단계에서 이중 작용기를 가지는 분자와 반응할 때 발생하며, 작은 분자량을 갖는 분자들 간의 축합반응과 유사하다. 이때, 작은 분자인 물이나 이산화탄소와 같은 물질은 제거되기도 한다.The synthesis of these polyureas is divided into two large areas: addition and condensation. Herein, the addition reaction is generated by reacting unsaturated monomers in the initiation step, development step, and termination step, wherein the monomers are simple molecules having a double bond. In the initiation step, one of the two double bonds reacts while breaking , The reaction proceeds rapidly until the unreacted monomer is almost lean. In most cases, the addition reaction proceeds without producing an adduct. The condensation reaction (or stepwise growth reaction) occurs when monomers react with a molecule having a double functional group at the step of forming a chain of the polymer, and is similar to the condensation reaction between molecules having a small molecular weight. At this time, small molecules such as water and carbon dioxide are sometimes removed.
여기서, 상기 부가반응은 균일 고분자나 공중합체로 구분할 수 있는데, 공중합체의 미세한 형태는 무작위, 교차, 덩어리 형태로 나눌 수 있지만, 이는 반응조건이나 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 축합반응 보다도 더 어려우며, 대부분 음이온 고분자화법에 의해 반응성이 조절되거나 어떤 경우에는 거의 단일 연쇄상 분포의 합성을 통해 반응성이 조절된다.Here, the addition reaction may be classified into a homogeneous polymer or a copolymer. The minute form of the copolymer may be divided randomly, crosswise, or lumpy, depending on reaction conditions, concentration, reactivity ratio of monomers, and the like. Furthermore, it is more difficult to control the molecular weight or the distribution of molecular weight after the reaction of the final reaction product, the polymer, than the condensation reaction which is controlled by using a reagent which changes the chain form, and in most cases, the reactivity is controlled by an anion- Reactivity is controlled through the synthesis of a single chain distribution.
또한, 상기 축합반응은 공중합 고분자물질을 만들 때도 사용되는데, 이중 작용기를 가지는 단량체들은 사슬형 고분자를 만들기 위해 이용되고 삼중 이상의 작용기를 가지는 단량체들은 3차원적 공간에 교차 결합 고분자 망을 구성할 수도 있다.In addition, the condensation reaction is also used to produce a copolymeric polymer material. The monomers having a double functional group are used for forming a chain polymer, and the monomers having three or more functional groups may constitute a crosslinked polymer network in a three-dimensional space .
한편, 상기와 같은 폴리우레아는, 관능기(또는 작용기)를 가지는 폴리옥시에테르 폴리아민 혼합물과 이소시아네이트 프리폴리머의 반응으로 형성되는 엘라스토머 특성을 갖는 고분자 물질로 아민과 이소시아네이트의 급속한 반응성 때문에 일반적으로 상온에서 혼합 사용할 수 없으며 이에, 특수한 스프레이 장비를 이용하여 도장 작업을 진행한다. 또한, 상기와 같은 폴리우레아는 합성고무와 같은 엘라스토머 성질을 가지기 때문에 콘크리트 구조물에 시공 후 자외선 및 대기 오염 물질에 의하여 내구성이 저하되어 물성이 급격히 떨어지는 문제점을 가지고 있다. On the other hand, the above-mentioned polyurea is a polymer material having an elastomeric property formed by the reaction of a polyoxyether polyamine mixture having a functional group (or functional group) and an isocyanate prepolymer, and can be generally used at room temperature because of the rapid reactivity of amine and isocyanate There is no special spray equipment to perform the painting work. In addition, since the polyurea has elastomeric properties such as synthetic rubber, it has a problem that the durability of the concrete structure is reduced due to ultraviolet rays and atmospheric pollutants after the construction, and the physical properties thereof are rapidly deteriorated.

본 발명에 따른 폴리우레아 도막 방수제에 의하면, 디올레일토코페릴메틸실란올과 쇼듐락테이트메틸실란올을 폴리머 분재 내에 도입하여 최종적으로 완결되는 폴리우레아의 내구성을 개선하여 물성 저하가 발생되지 않도록 할 수 있고, 붓이나 롤러 또는 에어리스 등을 사용하여 작업이 가능하여 작업효율을 향상시킬 수 있다.According to the polyurea coating film waterproofing agent of the present invention, by introducing dioleyltocopheryl methylsilanol and sodium dicaturated methylsilanol into the polymer blanket, the durability of the final polyurea is improved, And it is possible to work by using a brush, a roller, an airless or the like, thereby improving the working efficiency.
이하, 본 발명에 따른 폴리우레아 도막 방수제, 그 제조방법 및 그 방수제를 이용한 방수,방식 공법에 대해 상세히 설명한다. Hereinafter, the polyurea coating waterproofing agent according to the present invention, the method for producing the same, and the waterproofing method using the waterproofing agent will be described in detail.
먼저 본 발명에 따른 폴리우레아 도막 방수제는 기본적으로, 디올레일토코페릴메틸실란올과 쇼듐락테이트메틸실란올을 주성분으로 하는 제1혼합물과, 1,12-도데카노디이소시아네이트와 폴리옥시알킬렌글리콜카르복실레이트를 주성분으로 하는 제2혼합물로 이루어진 2액형 타입의 폴리우레아 도막 방수제 조성물인 것이 바람직하다.First, the polyurea coating waterproofing agent according to the present invention is basically composed of a first mixture composed mainly of diol rail tocopheryl methyl silanol and sodium dicarboxylate silanol, and a second mixture containing 1,12-dodecano diisocyanate and polyoxyalkylene glycol It is preferable that the composition is a two-part type polyurea coating film waterproofing composition composed of a second mixture containing a carboxylate as a main component.
여기서, 상기 제1혼합물은, 디올레일토코페릴메틸실란올 100중량부에 쇼듐락테이트메틸실란올 70~90중량부, N-폴리옥시알킬-N-알킬아민 30~50중량부 및 안료 3~5중량부로 구성되는 실란올 혼합물이다.Wherein the first mixture is prepared by mixing 70 to 90 parts by weight of a silanol chain siloxane, 30 to 50 parts by weight of N-polyoxyalkyl-N-alkylamine, 5 parts by weight of a silanol mixture.
또한, 상기 제2혼합물은, 1,12-도데카노디이소시아네이트 100중량부에 폴리옥시알킬렌글리콜카르복실레이트 70~80중량부, 세틸알콜에틸렌프로필렌코폴리머 60~70중량부, 트리에톡시테트라플로보레이트 30~40중량부 및 3,3-비스클로로메틸옥사사이클로뷰탄 10~20 중량부로 구성되는 혼합물이다.Also, the second mixture may be prepared by mixing 70 to 80 parts by weight of a polyoxyalkylene glycol carboxylate, 60 to 70 parts by weight of a cetyl alcohol ethylene propylene copolymer with 100 parts by weight of 1,12-dodecanedioisocyanate, 30 to 40 parts by weight of fluoroborate and 10 to 20 parts by weight of 3,3-bischloromethyloxycyclobutane.
여기서, 상기 디올레일토코페릴메틸실란올은 녹는점이 50℃이고 끓는점이 120~160℃이며 밀도가 1.4g/cm3이고, 상기 N-폴리옥시알킬-N-알킬아민은 아민가가 80~120이고 당량이 90~150 인 것이 바람직하다.The diol rail tocopheryl methyl silanol has a melting point of 50 ° C, a boiling point of 120 to 160 ° C and a density of 1.4 g / cm 3 , and the N-polyoxyalkyl-N-alkylamine has an amine value of 80 to 120 And an equivalent weight of 90 to 150 is preferable.
또한, 상기 폴리옥시알킬렌글리콜카르복실레이트는 수산기가가 70~130이고 수분이 0.03%이하이며 점도가 200~400cps이고, 상기 세틸알콜에틸렌프로필렌코폴리머는 무게평균분자량이 5000이고 점도가1100~1300cps이며, 상기 1,12-도데카노디이소시아네이트는 NCO%가 13~18 인 것이 바람직하다.The polyoxyalkylene glycol carboxylate has a hydroxyl value of 70 to 130, a water content of 0.03% or less and a viscosity of 200 to 400 cps. The cetyl alcohol ethylene propylene copolymer has a weight average molecular weight of 5,000 and a viscosity of 1,100 - 1300 cps, and the 1,12-dodecanediisocyanate preferably has an NCO% of 13 to 18.
한편, 상기 제1혼합물에 있어서, 상기 쇼듐락테이트메틸실란올의 경우, 함량이 70중량부 이하이면 내구성성이 떨어지고 90중량부 이상이면 경제성이 떨어지게 되어 70~90중량부를 가지는 것이 바람직하다. 그리고 상기 N-폴리옥시알킬-N-알킬아민의 경우, 사슬 연장제로서 함량이 30 중량부 이하이면 가교 반응도가 감소하여 도막의 강도나 신장율이 저조하게 되고 50 중량부 이상이면 미경화 부분이 발생하게 되어 70~80중량부를 가지는 것이 바람직하다. On the other hand, in the case of the above-mentioned first mixture, in the case of the above-mentioned modalactate methylsilanol, when the content is 70 parts by weight or less, the durability is poor, and when it is 90 parts by weight or more, economical efficiency is lowered. In the case of the N-polyoxyalkyl-N-alkylamine, if the content of the chain extender is 30 parts by weight or less, the degree of crosslinking decreases and the strength and elongation of the coating film become poor. When the amount is 50 parts by weight or more, Preferably 70 to 80 parts by weight.
또한, 상기 제2혼합물에서 상기 폴리옥시알킬렌글리콜카르복실레이트의 경우, 함량이 70중량부 이하이면 경화 시간이 길어져 부반응이 발생하여 물성 저하가 발생하게 되고 80중량부 이상이면 가사 시간이 너무 짧아서 작업성이 떨어지게 되어 70~80중량부를 가지는 것이 바람직하다. 그리고 상기 세틸알콜에틸렌프로필렌코폴리머의 경우, 함량이 60중량부 이하이면 반응도가 감소하고 70중량부 이상이면 수분과 반응하여 저분자량의 우레아가 형성되어 내구성이 급격히 감소하게 되어 60~70중량부를 가지는 것이 바람직하다. 그리고 상기 트리에톡시테트라플로보레이트의 경우, 함량이 30~40중량부 범위를 벗어나면 상기 1차 혼합물과 2차 혼합물의 반응비를 맞추기가 불가능하므로 30~40중량부를 가지는 것이 바람직하다. 그리고 상기 3,3-비스클로로메틸옥사사이클로뷰탄의 경우, 함량이 10~20중량부를 벗어나면 2차 혼합물 제조시 반응성을 조절하기가 매우 힘들기 때문에 10~20중량부를 가지는 것이 바람직하다.If the content of the polyoxyalkylene glycol carboxylate in the second mixture is less than 70 parts by weight, the curing time is prolonged and a side reaction occurs to deteriorate the physical properties. If the amount of the polyoxyalkylene glycol carboxylate is more than 80 parts by weight, It is preferable to have 70 to 80 parts by weight. If the content of the cetyl alcohol ethylene propylene copolymer is less than 60 parts by weight, the reactivity decreases. If the content of the cetyl alcohol ethylene propylene copolymer is more than 70 parts by weight, the low molecular weight urea is formed by reacting with water, thereby drastically decreasing the durability. . In the case of triethoxytetrafluoroborate, if the content of the triethoxytetrafluoroborate is out of the range of 30 to 40 parts by weight, it is impossible to match the reaction ratio of the primary mixture to the secondary mixture. In the case of 3,3-bischloromethyloxycyclobutane, it is preferable that the content of the 3,3-bischloromethyloxycyclobutane is 10 to 20 parts by weight because it is very difficult to control the reactivity when the content is out of 10 to 20 parts by weight.
