이하 첨부된 도면을 참고로 본 발명의 바람직한 실시예에 대하여 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
먼저, 도 1은 본 발명의 바람직한 실시예에 따른 친환경 방수도료 조성물을 제조하는 과정을 나타내는 순서도이다.First, Figure 1 is a flow chart showing a process for producing an environmentally friendly waterproof coating composition according to a preferred embodiment of the present invention.
도시된 바와 같이 본 발명의 친환경 방수도료 조성물 제조방법은 증점단계, 분산단계, 교반단계, 조색단계, 점도단계 등으로 이루어진다.As shown, the method for producing an environmentally friendly waterproof coating composition of the present invention comprises a thickening step, a dispersion step, a stirring step, a coloration step, a viscosity step and the like.
먼저 증점 단계에 대해 설명하기로 한다.First, the thickening step will be described.
상기 증점 단계는 교반기에 물3~10 중량부를 투입 후 셀룰로오스 증점제 0.01~0.05 중량부를 첨가하고 1000~1500rpm 의 속도로 교반하면서 수산화암모늄 0.01~0.15중량부로 증점하는 단계로서, 이는 후공정이 원활하게 진행되도록 하기 위함이다.The thickening step is to add 3 ~ 10 parts by weight of water to the stirrer and then add 0.01 ~ 0.05 parts by weight of cellulose thickener and thicken it with 0.01 ~ 0.15 parts by weight of ammonium hydroxide while stirring at a speed of 1000 ~ 1500rpm, which is a smooth post process To make it possible.
상기 물은 통상의 용매로 사용되는 것으로 그 사용량은 3~10중량부인데 만일 이 범위를 벗어나면 분산에 어려움이 생길 수 있다. The water is used as a conventional solvent, the amount of the use is 3 to 10 parts by weight, if outside this range may cause difficulty in dispersion.
상기 셀룰로오스는 증점제로 사용하는 것이며, 그 사용량은 0.01~0.05중량부인데, 만일 0.01중량부 미만이면 증점이 미미할 수 있으며, 반대로 0.05중량부를 초과하면 증점이 과하여 물이 추가로 요구되므로 물성이 떨어질 수 있다.The cellulose is used as a thickener, the amount of use is 0.01 ~ 0.05 parts by weight, if less than 0.01 parts by weight may be insignificant, on the contrary, if more than 0.05 parts by weight is excessively thickened additional water is required, so the physical properties may fall. have.
상기 수산화암모늄은 산도(pH)를 조절하기 위하여 사용하는 것으로 그 사용량은 0.01 내지 0.05 중량부인데 만일 0.01중량부 미만이면 산도가 pH8 내지 10을 유지하기 어려우며, 반대로 0.05 중량부를 초과하면 점도를 조절하기 어려울 수 있다.The ammonium hydroxide is used to adjust the acidity (pH) and its amount is used in 0.01 to 0.05 parts by weight, if less than 0.01 parts by weight of acidity is difficult to maintain pH 8 to 10, on the contrary to adjust the viscosity when exceeding 0.05 parts by weight It can be difficult.
그리고 증점 단계에서 교반속도는 1000~1500rpm의 속도를 유지하는데, 만일 1000rpm 미만이면 교반과 배합이 균일하게 진행되지 않을 수 있으며, 반대로 1500rpm 을 초과하면 기포가 생성되어 포장이 어려울 수 있다.And in the thickening step, the stirring speed is maintained at a speed of 1000 ~ 1500rpm, if less than 1000rpm agitation and mixing may not proceed uniformly, on the contrary, if it exceeds 1500rpm bubbles may be difficult to pack.
다음으로 분산단계는 상기 교반기에 프로필렌클리콜 0.1~0.8중량부, 분산제 0.1~0.5중량부를 첨가하여 10~20분 동안 2~4회 분산시키는 단계이다.Next, the dispersing step is a step of dispersing 2 to 4 times in 10 to 20 minutes by adding 0.1 to 0.8 parts by weight of propylene glycol, 0.1 to 0.5 parts by weight of a dispersant to the stirrer.
상기 프로필렌글리콜은 동계에도 얼지 않도록 동결방지제 역할을 하는 것으로 만일 0.1중량부 미만이면, 동결 방지에 악영향을 미칠 수 있으며, 반대로 0.8중량부를 초과하면 불필요한 자원의 낭비를 초래하여 제조원가를 상승시킬 수 있다.The propylene glycol acts as a cryoprotectant to prevent freezing even in winter, if less than 0.1 parts by weight, may adversely affect the freeze protection, on the contrary, if it exceeds 0.8 parts by weight, it may cause unnecessary resource waste and increase manufacturing costs.
상기 분산제의 사용량은 0.1 내지 0.5중량부인데, 만일 0.1중량부 미만이면 응집 불량이 생길 수 있고, 반대로 0.5중량부를 초과하면 내수성이 저하되며 불필요한 제조원가 상승의 요인이 될 수 있다. The amount of the dispersant is 0.1 to 0.5 parts by weight, if less than 0.1 parts by weight may cause aggregation failure, on the contrary, if it exceeds 0.5 parts by weight, the water resistance is lowered and may cause unnecessary manufacturing cost increase.
다음으로 교반 단계는 상기 교반기에 수성계 에틸렌-비닐아세테이트(Ethylene-vinylacetate)수지 25~35중량부, 물20~30중량부, 탄산칼슘(CaC03)10~15중량부, 산화칼륨(K2O)10~15중량부, 석화분말5~10중량부, 산화철(Fe2O3)1~5중량부,자연석분말 10~15중량부를 투입하여 800~1000rpm 속도로 교반하는 단계이다. Next, the stirring step is an aqueous ethylene-vinylacetate resin 25 to 35 parts by weight, 20 to 30 parts by weight of water, calcium carbonate (CaC0 3 ) 10 to 15 parts by weight, potassium oxide (K 2 O) 10 to 15 parts by weight, 5 to 10 parts by weight of petrified powder, 1 to 5 parts by weight of iron oxide (Fe 2 O 3 ), 10 to 15 parts by weight of natural stone powder is added and stirred at 800 to 1000 rpm.
상기 수성계 에틸렌-비닐아세테이트(Ethylene-vinylacetate)수지는 25~35중량부인 것이 바람직하며, 25중량부 미만인 경우에는 내수성, 굴곡성 및 접착력이 불량해지며, 35중량부 초과인 경우에는 난연 성능이 떨어진다.The aqueous ethylene-vinylacetate resin is preferably 25 to 35 parts by weight, when less than 25 parts by weight of water resistance, flexibility and adhesion is poor, when more than 35 parts by weight of flame retardant performance is poor. .
상기 물은 통상의 용매로 사용되는 것으로 그 사용량은 20~30중량부인데 만일 이 범위를 벗어나면 분산에 어려움이 생길 수 있다. The water is used as a common solvent, the amount of the use is 20 to 30 parts by weight, if it is out of this range may cause difficulty in dispersion.
상기 탄산칼슘은 도막의 두께를 유지시키기 위하여, 그 사용량은 10~15중량부인데, 만일 10중량부 미만이면 도료 조성물을 실제로 시공하는데 도막의 두께가 낮아져 반복되는 도장을 유발할 수 있으며, 반대로 15중량부를 초과하면 도막의 강도가 떨어질 수 있다.In order to maintain the thickness of the coating film, the calcium carbonate is used in an amount of 10 to 15 parts by weight, but if it is less than 10 parts by weight, the coating composition may be lowered to actually apply the coating composition, which may cause repeated coating, on the contrary, 15 parts by weight. Exceeding the portion may lower the strength of the coating film.
상기 산화칼륨(K2O)과 상기 산화철(Fe2O3)은 황토색, 적색, 적갈색 계열의 무기안료로서 이들의 사용함량은 처리 후에 나타나는 색을 고려해야 하므로 산화칼륨(K2O)은 10~15중량부가 적당하고, 상기 산화철(Fe2O3)1~5중량부가 적당하다. The potassium oxide (K 2 O) and the iron oxide (Fe 2 O 3 ) is an ocher, red, reddish brown-based inorganic pigments, the use of these should be considered as the color appears after treatment, potassium oxide (K 2 O) is 10 ~ 15 parts by weight is suitable, and 1 to 5 parts by weight of the iron oxide (Fe 2 O 3 ) is suitable.
상기 석화분말은 굴, 조개 껍데기와 같은 패류 껍질을 분쇄한 분말로서 친환경적인 천연 재료이다.The petrified powder is an environmentally friendly natural material as a powder obtained by grinding shells of shellfish such as oysters and shells.
이러한 석화분말은 10~15중량부가 함유되는 것이 가장 바람직하며, 이와 같은 범위 내일 때 냄새를 신속하게 증발시키며 다량의 환경 호르몬이 방출되는 것을 미연에 차단할 수 있다.The petrified powder is most preferably contained 10 to 15 parts by weight, and when in this range can quickly evaporate the odor and block the release of a large amount of environmental hormones.
