먼저, S1단계를 보면, 폴리올 1 내지 8 중량부 및 아마이드(amide) 1 내지 5 중량부를 100 내지 150℃ 온도로 25 내지 35 분동안 가열하여 제1용제를 준비하는 단계이다.First, in the step S1, 1 to 8 parts by weight of polyol and 1 to 5 parts by weight of amide (amide) are heated at 100 to 150 ° C. for 25 to 35 minutes to prepare a first solvent.
상기 폴리올은 폴리에테르폴리올, 폴리프로필렌글리콜일 수 있으며, 그 사용량은 1 내지 8 중량부이다. 만일, 상기 폴리올이 1 중량부 미만이면, 상기 아마이드가 반응하지 않은 부산물로 남을 수 있으며, 반대로 8 중량부를 초과하면, 상기 폴리올이 반응하지 않은 채 부산물로 남을 수 있다.The polyol may be a polyether polyol, polypropylene glycol, the amount of which is 1 to 8 parts by weight. If the polyol is less than 1 part by weight, the amide may remain as an unreacted byproduct. If the polyol exceeds 8 parts by weight, the polyol may remain as a byproduct without reacting.
또한, 상기 아마이드는 특별하게 제한하여 사용할 것은 아니며, 폴리아마이드가 사용될 수 있고, 여기서 그 사용량은 1 내지 5 중량부일 수 있는데, 만일 상기 아마이드가 1 중량부 미만이며, 상기 폴리올이 반응하지 않은 부산물로 남을 수 있으며, 반대로 5 중량부를 초과하면, 상기 아마이드가 반응하지 않은 채 부산물로 남을 수 있다.In addition, the amide is not particularly limited to use, polyamide may be used, where the amount of the amide may be 1 to 5 parts by weight, if the amide is less than 1 part by weight, the polyol as a by-product unreacted On the contrary, if it exceeds 5 parts by weight, the amide may remain as a by-product without reacting.
아울러, 상기 폴리올과 아마이드르 혼합하여 100 내지 150℃로 가열하게 되는데, 만일 100℃ 미만이면, 반응이 충분하게 이루어지지 않을 수 있으며, 반대로 150℃를 초과하면, 상기 폴리올이나 아마이드가 급격한 반응으로 원하지 아니하는 부산물이 발생할 수 있으며, 여기서 반응시간은 25 내지 35분이 적당한데, 이 범위를 벗어나면, 미반응물이 잔존하거나 원하지 아니하는 부산물이 발생할 수 있어 바람직하지 아니하다.In addition, the polyol and amide are mixed and heated to 100 to 150 ° C., if less than 100 ° C., the reaction may not be sufficiently performed. On the contrary, if the polyol or amide exceeds 150 ° C., the polyol or amide may be rapidly reacted. No by-products may be generated, where the reaction time is appropriately 25 to 35 minutes. Outside this range, unreacted products may remain or unwanted by-products may occur.
다음으로, S2단계를 보면, 색소 1 내지 5 중량부, 폴리올 10 내지 30 중량부, 분산제 0.01 내지 0.08 중량부, 증점제 0.5 내지 1 중량부, 중탄산칼슘(Ca(CO3)2) 30 내지 80 중량부 및 크실렌 1 내지 3 중량부를 순차적으로 첨가하며 1000 내지 1200rpm의 속도로 교반한 후 소포제 0.2 내지 0.6 중량부를 첨가하여 주제부를 준비하는 단계이다.Next, looking at the step S2, the pigment 1 to 5 parts by weight, polyol 10 to 30 parts by weight, dispersant 0.01 to 0.08 parts by weight, thickener 0.5 to 1 parts by weight, calcium bicarbonate (Ca (CO 3 ) 2 ) 30 to 80 weight Part and 1 to 3 parts by weight of xylene are sequentially added and stirred at a speed of 1000 to 1200 rpm, followed by preparing a main part by adding 0.2 to 0.6 parts by weight of an antifoaming agent.
상기 색소는 원하는 색상을 가지는 통상의 색소를 사용할 수 있으며, 특별하게 한정하여 이용할 것은 아니다. 또한, 상기 색소를 1 내지 5 중량부로 사용하는데, 만일, 1 중량부 미만이면 착색력이 부족하여 색상이 발현되기 어려우며, 반대로, 5 중량부를 초과하면 원가상승의요인이 될 수 있고 다른 함유물의 상대적이 양이 줄게 되어 본 조성물의 물성이 제한될 수 있다.The said pigment can use the usual pigment | dye which has a desired color, It does not specifically limit and use. In addition, the pigment is used in 1 to 5 parts by weight, if less than 1 part by weight is difficult to express the color due to lack of coloring power, on the contrary, if it exceeds 5 parts by weight can be a factor of the cost increase and the relative content of other Reduced amount may limit the physical properties of the composition.
또한 상기 폴리올을 10 내지 30 중량부로 사용하는데, 만일, 10중량부 미만이면 가열하여 용해되는 성능이 저하될 수 있으며, 반대로 30 중량부를 초과하면 다른 함유물의 조성이 상대적으로 줄게 될 수 있다.In addition, the polyol is used in 10 to 30 parts by weight, if less than 10 parts by weight may degrade the ability to dissolve by heating, on the contrary, if it exceeds 30 parts by weight may be relatively reduced in the composition of the other inclusions.
또한, 상기 분산제는 상기 중탄산칼슘과 액상들이 균일하게 혼합분산되도록 하기 위해 사용하는 것이며, 그 사용량은 0.01 내지 0.08 중량부이다. 만일, 이 범위를 벗어나면, 이산화티탄이 균일하게 분산되지 않거나 저장안정성에 악영향을 미칠 수 있다.In addition, the dispersant is used to uniformly disperse and disperse the calcium bicarbonate and the liquid phase, the amount is 0.01 to 0.08 parts by weight. If outside this range, the titanium dioxide may not be uniformly dispersed or may adversely affect the storage stability.
상기 증점제는 최종 공정이후에 상기 주제부를 장기간 보관하는 경우에 침전물이 발생하는 것을 방지하며 또한, 실제 건설현장에서 시공하는 경우에 흘러내림 불량의 발생을 방지하며 시공완료후에 접착력을 부여하는 기능을 한다. 상기 증점제는 그 사용량이 0.5 내지 1 중량부이다. 만일 0.5 중량부 미만이면, 색상이 균일하지 않을 수 있고 저장안정성에 악영향을 미칠 수 있으며, 반대로 1 중량부를 초과하면 점도가 높아져서 실제 시공시에 도막의 평활성이 저하될 수 있다.The thickener prevents sediment from occurring when the main part is stored for a long time after the final process, and also prevents the occurrence of deterioration defects in case of construction at the actual construction site, and provides adhesion after completion of construction. . The thickener is used in an amount of 0.5 to 1 parts by weight. If it is less than 0.5 parts by weight, the color may not be uniform and may adversely affect the storage stability. On the contrary, if it is more than 1 part by weight, the viscosity may be increased to reduce the smoothness of the coating film during actual construction.
한편, 상기 중탄산칼슘 30 내지 80 중량부를 투입하는데, 그 이유는 도막두께를 증가시키고 제조원가를 낮추기 위하여 사용하는 것이다. 그런데, 만일 30 중량부 미만이면, 점도가 낮아져 도막두께가 얇아지는 관계상 추가적인 도장작업을 초래하고 은폐력이 저감되며, 반대로 80 중량부를 초과하면 광택성 및 내오염성에 영향을 미치고 도장된 면이 거칠어질 수 있다.On the other hand, 30 to 80 parts by weight of the calcium bicarbonate is added, the reason is to use to increase the film thickness and lower the manufacturing cost. However, if it is less than 30 parts by weight, the viscosity is lowered, resulting in a thinner coating film, resulting in additional coating work and reducing the hiding power. On the contrary, if it exceeds 80 parts by weight, the gloss and stain resistance are affected and the coated surface is rough. Can lose.
상기 크실렌(Xylene)은 용매로 사용되는데, 그 사용량은 1 내지 3 중량부이다. 만일 이 범위를 벗어나면 상기 이산화티탄이 균일하게 분사되지 않거나 시간이 흐름에 따라 층분리가 일어날 수 있다.The xylene (Xylene) is used as a solvent, the amount is 1 to 3 parts by weight. If out of this range, the titanium dioxide may not be uniformly sprayed or layer separation may occur over time.
여기서, 상기 색소, 폴리올, 분산제, 증점제, 중탄산칼슘(Ca(CO3)2) 및 크실렌을 순차적으로 첨가하며 1000 내지 1200rpm의 속도로 교반하게 되는데, 만일 1000rpm 미만이면, 제조공정시간이 늘어나게 되어 원가상승이 우려되며, 반대로 1200rpm을 초과하면 본 조성물에 기포가 함유되어 제품의 품위가 절감될 수 있다.Here, the dye, polyol, dispersant, thickener, calcium bicarbonate (Ca (CO 3 ) 2 ) and xylene are sequentially added and stirred at a speed of 1000 to 1200rpm, if less than 1000rpm, manufacturing process time is increased On the contrary, if it exceeds 1200rpm, bubbles may be contained in the present composition, which may reduce product quality.
이어서 소포제를 0.2 내지 0.6 중량부를 첨가하게 되는데, 상기 소포제는 교반중에 기포의 발생을 억제하는 역할을 하는데, 만일 0.2 중량부 미만이면 기포의 발생을 억제하는 효과가 떨어지며, 반대로 0.6 중량부를 초과하면 불필요한 낭비를 초래할 수 있다.Then, an antifoaming agent is added to 0.2 to 0.6 parts by weight. The antifoaming agent serves to suppress the generation of bubbles during stirring. If less than 0.2 parts by weight, the effect of suppressing the generation of bubbles is reduced. It may cause waste.
다음으로, S3단계를 보면, 별도로 준비된 반응기에 폴리올 55 내지 75 중량부, 산촉매로 황산 0.5 중량부를 첨가후 50 내지 70℃에서 가소제 5 내지 15 중량부를 더 첨가하고, 70 내지 90℃에서 3 내지 5시간동안 가열한 후, 이소시아네이트 15 내지 30 중량부, 촉진제 0.01 내지 0.1 중량부를 첨가후 균일하게 교반하여 경화제부를 준비하는 단계이다.Next, in step S3, 55 to 75 parts by weight of polyol and 0.5 parts by weight of sulfuric acid are added to the reactor prepared separately, and then 5 to 15 parts by weight of plasticizer is added at 50 to 70 ° C, and 3 to 5 at 70 to 90 ° C. After heating for a time, 15 to 30 parts by weight of isocyanate and 0.01 to 0.1 parts by weight of accelerator are added, followed by uniformly stirring to prepare a curing agent part.
먼저 폴리올 55 내지 75 중량부를 이용하는데, 만일 상기 폴리올이 55 중량부 미만이면, 건조가 너무 빨라서 작업성이 저하되고 시공후 도막이 깨짐성이 커질 수 있고, 반대로 75 중량부 초과하면, 건조가 불충분해질 수 있다.First, 55 to 75 parts by weight of polyol is used.

또한, 상기 촉진제는 아민계를 사용할 수 있는데, 디에틸렌트리아민, 트리에틸아민, 트리에탄올아민 또는 테트라부틸트리아민가 바람직하다. 여기서 그 사용량은 0.01 내지 0.1 중량부인데, 만일 이 범위를 벗어나면, 주변환경의 온도변화에 의하여 반응이 지연되거나 불필요한 자원이 낭비될 수 있다.In addition, the accelerator may be an amine, preferably diethylenetriamine, triethylamine, triethanolamine or tetrabutyltriamine. Here, the amount is 0.01 to 0.1 parts by weight, if out of this range, the reaction may be delayed or unnecessary resources are wasted due to the temperature change of the surrounding environment.
다음으로, S4단계를 보면, 상기 주제부와 경화제부를 중량기준으로 2.5:1 내지 3.5:1 비율로 50 내지 100rpm의 속도로 교반하여 바닥재용 도료조성물을 준비하는 단계이다.Next, looking at the step S4, the main part and the curing agent is a step of preparing a paint composition for the flooring material by stirring at a rate of 50 to 100rpm in a ratio of 2.5: 1 to 3.5: 1 by weight.
상기 주제부와 경화제부를 중량기준으로 2.5:1 내지 3.5:1 비율로 이용하는데, 만일 이 범위를 벗어나면 건조가 불충분해질 수 있고 내약품성이 저하될 수 있으며, 물리적강도가 저감될 수 있는 문제가 있다.The main part and the hardener part are used in a ratio of 2.5: 1 to 3.5: 1 by weight. If it is out of this range, drying may be insufficient, chemical resistance may decrease, and physical strength may be reduced. have.
또한, 교반속도를 50 내지 100rpm으로 하게 되는데, 만일 50rpm 미만이면, 혼합공정시간이 늘어나게 되어 작업지연이 우려되며 반대로, 100rpm을 초과하면 본 조성물에 기포가 함유되어 제품의 품위가 절감될 수 있다.In addition, the stirring speed is 50 to 100rpm, if less than 50rpm, the mixing process time is increased and the work delay is feared, on the contrary, if it exceeds 100rpm may contain bubbles in the composition can reduce the product quality.
