Description
본 발명은 식품,제약,엔지니어링,전자,화학공장 등의 산업현장에서 요구하는 극도의 위생상태와 특수한 물리,화학적인 물성조건과 표면의 거칠기를 모두 만족시킬 수 있는 저휘발성 유기화합물(VOC)의 친환경적인 수용성 에폭시 코팅재 조성물 및 무기물을 보강한 에폭시 코팅재 조성물의 시공방법에 관한 것으로 더욱 상세하게는 열경화성수지를 개량 수정하여 물리적,화학적 특성을 부여한 조성물로 내약품성을 강화시킨 수정된 지방족화합물 작용제(Agents modify aliphatic) 수지로서 코팅재,바닥재,보조봉쇄 및 라이닝 등에 적용할 수 있게 한 것이다.The present invention provides a low volatility organic compound (VOC) capable of satisfying both the extreme hygienic conditions required for industrial sites such as food, pharmaceutical, engineering, electronics, chemical plants, and special physical and chemical property conditions and surface roughness. The present invention relates to a method for constructing an environment-friendly water-soluble epoxy coating composition and an inorganic reinforcing epoxy coating composition, and more particularly, a modified aliphatic compound agent having improved chemical resistance by modifying and modifying a thermosetting resin to give physical and chemical properties. modify aliphatic) This resin can be applied to coating materials, flooring materials, secondary containment and lining.
일반적으로 콘크리트로 시공되는 구조물의 바닥재와 금속 및 합성수지 등의 각종 표면을 보호 및 강화시키고 환경구조를 개선하기 위한 마감재로 화학수지를 이용한 공법이 주로 적용되고 있으며 화학수지 중에서도 대부분 물성이 우수한 에폭시수지를 주로 이용하고 있는 실정이다.In general, a method using chemical resin is mainly applied as a finishing material for protecting and strengthening various materials such as flooring of metal structures, metals and synthetic resins, and improving the environmental structure. Among the chemical resins, most epoxy resins have excellent physical properties. It is mainly used.
종래에 사용되어온 에폭시수지를 이용한 코팅재 조성물은 크게 무용제형과 용제형의 두가지로 구분할 수 있다.The coating material composition using the epoxy resin that has been conventionally used can be largely divided into two types, a solventless type and a solvent type.
상기 무용제형은 유기용제를 이용하지 않는 것이 원칙이나 용도에 따라 소량의 용제를 이용하기도 하고 셀프레벨링(Self-leveling)성으로 인하여 수지액을 바닥면에 도포하여 3-5mm 내외의 일정한 두께로 평탄면을 가지나 사용범위가 구조물의 바닥면에 한정된다는 문제가 있었다.The non-solvent type may use a small amount of solvent depending on the principle or purpose of not using an organic solvent, and may apply a resin solution to the bottom surface due to self-leveling property to flatten to a constant thickness of about 3-5 mm. There was a problem that it has a face, but the use range is limited to the bottom surface of the structure.
그리고 상기 용제형의 경우에는 에폭시 액상수지의 점성을 용제에 용해시켜 묽게 함으로써 작업성 향상과 균일한 박막을 형성하도록 하는 조성물로서 다량의 혼합 유기용제를 필수적으로 사용하여야 한다.In the case of the solvent type, a large amount of a mixed organic solvent must be used as a composition for improving workability and forming a uniform thin film by dissolving and diluting the viscosity of the epoxy liquid resin in a solvent.
상기와 같이 다량의 유기용제를 사용하여 조성하는 이유는 에폭시수지의 기본 베이스 액상점도가 20℃에서 11,000-22,000cps이고 용제형 코팅재에 포함되는 반응성 희석제의 점도 또한 20℃에서 1,000-5,000cps로서 용제를 10% 내외로 소량 사용할 경우에는 저점도 형성이 불가능하기 때문이다.The reason for the composition using a large amount of organic solvent as described above is that the basic base liquid viscosity of the epoxy resin is 11,000-22,000 cps at 20 ° C., and the viscosity of the reactive diluent included in the solvent type coating material is also 1,000-5,000 cps at 20 ° C. If a small amount of about 10% is used, low viscosity cannot be formed.
따라서 용제형으로 얇은 박막을 형성하기 위해서는 그동안 유기용제를 전체량에 대해 60% 정도로 다량 함유되도록 조성하고 있으며 현장에서 10% 내외로 용제를 후첨가하여 사용하고 있었다.Therefore, in order to form a thin thin film in the solvent type, the organic solvent has been formed so as to contain a large amount of about 60% of the total amount, and the solvent was used after the addition of about 10% in the field.
상기와 같은 저점도 형상을 유지해야 하는 이유는 작업성을 원활히 하고 균일성을 확보하는 동시에 0.2mm 내외의 박막을 유지하여 신속한 용출이 가능케 하여 경화 반응 시 가교성을 저해받지 않고 원만한 경화 물성이 얻어지도록 하기 위함이다.The reason for maintaining the low viscosity shape as described above is to facilitate workability and ensure uniformity, and to maintain a thin film of about 0.2mm and to enable rapid dissolution to obtain smooth curing properties without being impaired in crosslinking properties during the curing reaction. To lose.
상기한 종래의 용제형 방법은 작업성과 균일성이 우수하고 조성물을 신속하게 용출시키기는 편리하나 용해력이 높은 유기용제를 다량으로 사용하기 때문에 인체와 환경에 유해하고 친환경적이 못하여 국내외에서 상기한 문제를 해결하기 위하여 다양한 방법의 연구가 요구되고 있다.
The conventional solvent-type method is excellent in workability and uniformity, it is convenient to quickly elute the composition, but because it uses a large amount of high solvents of organic solvents harmful to the human body and the environment, it is not environmentally friendly and solves the above problems at home and abroad To solve this problem, various methods of research are required.
따라서 본 발명은 상기와 같은 종래의 문제점을 개선하기 위하여 창출된 것으로 내화학약품인 열경화성수지를 변성,수정하여 물리적 및 화학적 특성을 부여시키고 무기질이 제공하는 친수 수화작용의 장점을 가진 조성물을 제공하여 친환경적인 현장시공이 가능케 한 소재로서 무용제형(솔벤트,톨루엔 무함유)으로 일반 에폭시나 우레탄 소재의 바닥재에 비해 시공시 냄새가 없고 일정한 정도(콘크리트 타설 5-6일 후,폴리머 시멘트계 바닥재 2-4일 후)의 습윤상태에서도 시공이 가능하여 시공기일의 단축이 가능하며 20℃에서 12-16시간 양생 후 경보행 및 24시간 양생 후 차량 통행이 가능한 빠른 경화속도를 가지고 화학물질에 노출되는 현장에서 고온의 상태에서 화학물질로부터(예:황산 98%, 염산 35%, 가성소다 20%, 불산 25% 각 약품에 섭씨 60도에서 시편을 72시간 침지 후 외관변화 부풀음 균열을 육안 관찰하여 이상없음)내화학성을 가지며 최대 영하 40도에서 130도까지의 온도 조건에서 사용이 가능한 내열성 및 내한성을 가지고 강한 기계적 강도와 낮은 탄성계수로 내충격성과 탄성을 유지하며 내구성과 내마모성이 우수하여 장기간 사용이 가능하고 화재시 유독가스가 발생하지 않는 난연성으로 인하여 화재 시 안전관리가 가능한 조성물과 그 시공방법을 제공할 수 있게 하였다.
Therefore, the present invention was created to improve the conventional problems as described above, by modifying and modifying the thermosetting resin, which is a chemical agent, to give physical and chemical properties and to provide a composition having the advantages of hydrophilic hydration provided by minerals. It is a solvent-free material (solvent-free, toluene-free) that has no odor during construction compared to general epoxy or urethane flooring materials and has a certain degree (after 5-6 days of concrete casting, polymer cement flooring materials).
