이것에 의해, 박도한 부위에 급속한 수분 증발 및 경화 수축을 억제함으로써 균열 및 들뜸 현상, 그리고 부스러짐을 해소하는 효과가 있다.As a result, there is an effect of eliminating cracking, lifting phenomenon and crumbs by suppressing rapid water evaporation and curing shrinkage at thin sites.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

건축 구조물의 노출 부위 바닥, 비노출부위 바닥, 외벽, 및 내벽에 방수 처리를 위하여 아크릴 수지 몰탈을 박도할 때, 급속 증발을 억제하기 위하여 경화 지연제와, 경화 수축을 방지하기 위하여 팽창제를 일정한 비율로 혼합한다.When the acrylic resin mortar penetrates the exposed floor, the non-exposed floor, the outer wall, and the inner wall of the building structure for waterproofing, a curing retardant is used to suppress rapid evaporation, and a swelling agent is used at a constant rate to prevent curing shrinkage. Mix.

일반적으로 아크릴 수지 몰탈(Acrylic copolymer Mortar)은 아크릴 수지, 시멘트, 규사의 혼합물이다. 아크릴 수지 몰탈의 박도는 3mm 이하의 두께로 엷게 바르는 것이다.Generally, acrylic copolymer mortar is a mixture of acrylic resin, cement and silica sand. The thickness of the acrylic resin mortar is lightly applied with a thickness of 3 mm or less.

바람직하기로는, 본 발명에 따른 아크릴 수지 몰탈은 아크릴 수지(Acrylic copolymer) 23-31 중량%, 시멘트 23-31 중량%, 규사 30-48 중량%, 경화 지연제로써 구연산(Citric acid)0-2중량%, 팽창제로써 황산 칼슘(CaSO4) 4-8중량%로 혼합된다. 여기서 상기 아크릴 수지의 고형분은 45-55%이고, 규사는 Φ0.15-0.60mm이며 이하 동일하다.Preferably, the acrylic resin mortar according to the present invention is 23-31% by weight acrylic resin, 23-31% by weight cement, 30-48% by weight of silica sand, citric acid as a curing retardant By weight, 4-8% by weight calcium sulfate (CaSO 4 ) as the expanding agent. Here, the solid content of the acrylic resin is 45-55%, silica sand is 0.15-0.60mm and is the same below.

본 발명에 따른 아크릴 수지 몰탈가 건축물의 노출된 바닥면을 박도할 때는 아크릴 수지 30 중량%, 시멘트 30 중량%, 규사 30 중량%, 경화 지연제로써 구연산 2 중량%, 팽창제로써 황산 칼슘 8 중량%로 혼합될 때가 가장 바람직하다.When the acrylic resin mortar according to the present invention penetrates the exposed floor of the building, 30% by weight of acrylic resin, 30% by weight of cement, 30% by weight of silica sand, 2% by weight of citric acid as a curing retardant, and 8% by weight of calcium sulfate as an expanding agent. Most preferably when mixed.

본 발명에 따른 아크릴 수지 몰탈가 건축물의 비노출된 바닥면을 박도할 때는 아크릴 수지 23 중량%, 시멘트 23 중량%, 규사 46 중량%, 경화 지연제로써 구연산 2 중량%, 팽창제로써 황산 칼슘 6 중량%로 혼합될 때가 가장 바람직하다.When the acrylic resin mortar according to the present invention permeates the unexposed floor of the building, 23% by weight of acrylic resin, 23% by weight of cement, 46% by weight of silica sand, 2% by weight of citric acid as a curing retardant, and 6% by weight of calcium sulfate as an expanding agent. Most preferably when mixed.

본 발명에 따른 아크릴 수지 몰탈가 건축물의 외벽을 박도할 때는 아크릴 수지 31 중량%, 시멘트 31 중량%, 규사 31 중량%, 경화 지연제로써 구연산 1 중량%, 팽창제로써 황산 칼슘 6 중량%로 혼합될 때가 가장 바람직하다.When the acrylic resin mortar according to the present invention penetrates the outer wall of the building, when mixed with 31% by weight of acrylic resin, 31% by weight of cement, 31% by weight of silica sand, 1% by weight of citric acid as a curing retardant and 6% by weight of calcium sulfate as an expanding agent Most preferred.

본 발명에 따른 아크릴 수지 몰탈가 건축물의 내벽을 박도할 때는 아크릴 수지 24 중량%, 시멘트 24 중량%, 규사 48 중량%, 경화 지연제로써 구연산 0 중량%, 팽창제로써 황산 칼슘 4 중량%로 혼합될 때가 가장 바람직하다.When the acrylic resin mortar according to the present invention penetrates the inner wall of the building, 24% by weight of acrylic resin, 24% by weight of cement, 48% by weight of silica sand, 0% by weight of citric acid as a curing retardant and 4% by weight of calcium sulfate as an expanding agent Most preferred.

이상과 같이 건축물의 노축 바닥면, 비노출 바닥면, 외벽 및 내벽에 각각 적합한 아크릴 수지 몰탈의 구성 성분을 제시하였는데, 어느 경우에서나, 아크릴 수지의 비율이 23-31 중량%의 범위 이하에서는 접착력이 저하되었고, 상기 범위 이상에서는 압축 강도가 저하되었다.As described above, constituents of acrylic resin mortar suitable for the unexposed floor surface, unexposed floor surface, outer wall and inner wall of the building were presented. In any case, the adhesive strength decreases when the proportion of the acrylic resin is 23-31% by weight or less. And the compressive strength was lowered above the above range.

또한, 시멘트의 혼합 비율이 23-31 중량%의 범위 이하에서는 신축율이 저하되어 균열이 발생되는 경우가 많았고, 상기 범위 이상에서는 압축 강도가 저하되었다.Moreover, when the mixing ratio of cement was below the range of 23-31 weight%, expansion | contraction rate fell and cracks were generate | occur | produced in many cases, and compressive strength fell below the said range.

또한, 규사의 혼합 비율이 상대적으로 높으면, 압축 강도는 증가하나 신축율이 저하되었고, 구연산의 혼합 비율이 0-2 중량%의 범위 이상에서는 흘러 처짐이 발생하였고, 상기 범위 이하에서는 경화 지연 효과를 발휘하지 못하였다.In addition, when the mixing ratio of silica sand was relatively high, the compressive strength was increased, but the expansion ratio was decreased, and the sagging occurred at the mixing ratio of citric acid in the range of 0-2% by weight or more. Did not exercise.

또한, 팽창제를 일정량의 비율로 혼합하면 균열 장비 효과를 얻을 수 있었고, 부수적으로 박도의 자동 수평의 효과도 있지만, 4-8 중량% 이상에서는 아크릴 수지 몰탈의 밀도가 낮아져서 압축 강도가 저하되며, 그 범위 이하의 비율에서는 경화 수축 방지가 어려웠다.In addition, when the expansion agent is mixed in a certain amount of ratio, the cracking equipment effect can be obtained, and incidentally, there is also an automatic horizontal effect of thinning. Hardening shrinkage prevention was difficult at the ratio below the range.

상술한 바와 같이 본 발명에 따른 아크릴 수지 몰탈은 아크릴 주지, 시멘트 및 규사의 혼합물에 경화지연제 및 팽창제를 함께 혼합하기 때문에 급속한 수분 증발 및 경화 수축을 억제함으로써 균열 및 들뜸 현상, 그리고 부스러짐을 해소하는 효과가 있다.As described above, the acrylic resin mortar according to the present invention mixes a curing retarder and an expanding agent together with a mixture of acrylic resins, cement and silica sand, thereby eliminating rapid moisture evaporation and curing shrinkage, thereby eliminating cracking and lifting and brittleness. It works.

이상에서 설명한 것은 본 발명에 따른 아크릴 수지 몰탈의 시공방법을 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구의 범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is just one embodiment for carrying out the construction method of the acrylic resin mortar according to the present invention, the present invention is not limited to the above-described embodiment, of the present invention claimed in the following claims Various changes can be made by those skilled in the art without departing from the gist of the present invention.
