이하 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.
본 발명의 모르타르 조성물 중에 사용되는 1차 조성물은 산화칼슘(CaO) 30~49중량%, 산화알루미늄(Al2O3) 20~35중량%, 삼산화황(SO3) 14~28중량%, 산화철(Fe2O3) 2~10중량%, 산화마그네슘(MgO) 2~10중량%, 이산화티타늄(TiO2) 1~5중량%, 타타르산(C4H6O6) 0.2~5중량% 및 폴리비닐알콜 0.1~5중량%를 포함한다. The primary composition used in the mortar composition of the present invention is calcium oxide (CaO) 30 to 49% by weight, aluminum oxide (Al 2 O 3 ) 20 to 35% by weight, sulfur trioxide (SO 3 ) 14 to 28% by weight, iron oxide ( Fe 2 O 3 ) 2 to 10% by weight, magnesium oxide (MgO) 2 to 10% by weight, titanium dioxide (TiO 2 ) 1 to 5% by weight, tartaric acid (C 4 H 6 O 6 ) 0.2 to 5% by weight and It contains 0.1 to 5% by weight of polyvinyl alcohol.
본 조성물 중에서 산화칼슘(CaO)은 음집, 흡수하는 기능을 하며, 산화알루미늄(Al2O3)은 무기접착 팽창 보조, 삼산화황(SO3)은 촉매, 산화철(Fe2O3)은 흡수, 산화마그네슘(MgO)은 흡착, 이산화티타늄(TiO2)은 촉매 분산, 타타르산은 지연, 폴리비닐알콜은 부착균열방지 등의 역할을 한다. 그러나 이는 본 조성물 중에서 각 성분의 대표적인 기능 및 역할일 뿐 각 성분의 기능 및 역할이 이에 국한되는 것은 아니다. In this composition, calcium oxide (CaO) functions to collect and absorb, and aluminum oxide (Al 2 O 3 ) assists in inorganic adhesive expansion, sulfur trioxide (SO 3 ) is a catalyst, and iron oxide (Fe 2 O 3 ) is absorbed and oxidized. Magnesium (MgO) is adsorbed, titanium dioxide (TiO 2 ) is used to disperse the catalyst, tartaric acid is delayed, and polyvinyl alcohol prevents adhesion cracking. However, this is only a representative function and role of each component in the composition, and the function and role of each component is not limited thereto.
폴리비닐알콜은 중합도가 30~30,000 사이이고 검화도(폴리비닐아세테이트가 알칼리 조건에서 비누화되어 아세테이트기가 수산기로 전환된 정도)가 50~100%인 것을 사용하는 것이 바람직하다. 폴리비닐알콜은 인장강도를 증진시키고 균열발생을 억제하며 균열이 발생한 후에는 균열의 폭을 감소시키고 내구성을 향상시키고 시공하는 과정에서 시공체의 표면에 부착이 잘되도록 도와주며 낮은 온도에서 증발하는 습기를 유인, 제거하기 위하여 사용한다.It is preferable to use polyvinyl alcohol having a degree of polymerization of 30 to 30,000 and a degree of saponification (a degree of conversion of an acetate group to a hydroxyl group by saponification of polyvinyl acetate in an alkaline condition) of 50 to 100%. Polyvinyl alcohol improves tensile strength and suppresses cracking. After cracking occurs, it reduces the width of cracks, improves durability, helps adhere well to the surface of the construction during construction, and evaporates moisture at low temperatures. It is used to attract and eliminate.
