It is preferably included in the content of weight percent. Specifically, the water soluble polymer consists of, for example, 50% polymer solids and 50% water. Depending on the application, there are products with a polymer solid content of 50% or less depending on the manufacturer, which means that the water-soluble polymer has a lot of water, and this has a property of delaying curing, so it is better to use a high solid content. It is preferable.
상기 수용성 폴리머에는 표면강화제의 물성을 증진시키기 위하여, 기타 첨가제로서 평활제, 소포제, 분산제, 증점제 및 경화촉진제로 이루어진 군에서 선택되는 어느 하나 이상이 추가로 첨가될 수 있다.In order to enhance the physical properties of the surface strengthening agent, any one or more selected from the group consisting of a smoothing agent, an antifoaming agent, a dispersing agent, a thickener and a curing accelerator may be further added to the water-soluble polymer.
상기 평활제는 실리콘류 또는 왁스류가 사용될 수 있으나 이에 제한되는 것 은 아니며, 당업계에서 통상적으로 사용되는 종류가 사용될 수 있다. 상기 평활제는 물성 증진과 전체 성분과의 조화를 위하여 수용성 폴리머 100중량부에 대하여 0.5~2.0중량부가 더 첨가되는 것이 바람직하다.Silicones or waxes may be used as the leveling agent, but are not limited thereto. A type commonly used in the art may be used. The leveling agent is preferably added to 0.5 to 2.0 parts by weight based on 100 parts by weight of the water-soluble polymer in order to improve the physical properties and coordination of the whole component.
소포제는 음이온성, 양이온성 또는 비이온성이 사용될 수 있으나 이에 제한되는 것은 아니며, 당업계에서 통상적으로 사용되는 종류가 사용될 수 있다. 상기 소포제는 물성 증진과 전체 성분과의 조화를 위하여 수용성 폴리머 100중량부에 대하여 0.5~2.0중량부 첨가되는 것이 바람직하다.Antifoaming agents may be used anionic, cationic or nonionic, but is not limited thereto, and the type commonly used in the art may be used. The antifoaming agent is preferably added in an amount of 0.5 to 2.0 parts by weight based on 100 parts by weight of the water-soluble polymer in order to enhance physical properties and balance with all the ingredients.
분산제는 음이온성, 양이온성 또는 비이온성 등이 사용될 수 있으나 이에 제한되는 것은 아니며, 당업계에서 통상적으로 사용되는 종류가 사용될 수 있다. 상기 분산제는 물성 증진과 전체 성분과의 조화를 위하여 수용성 폴리머 100중량부에 대하여 0.5~2.0중량부 첨가되는 것이 바람직하다.The dispersant may be anionic, cationic or nonionic, and the like, but is not limited thereto. A type commonly used in the art may be used. The dispersant is preferably added in an amount of 0.5 to 2.0 parts by weight based on 100 parts by weight of the water-soluble polymer in order to enhance physical properties and balance with all components.
상기 에틸렌 글리콜(ethylene glycol)은 수용성 폴리머 100중량부에 대하여 0.5~1.0중량부 포함되는 것이 바람직하며, 이러한 범위로 첨가할 경우 기존 표면강화제의 단점 중 하나인 저온에서의 안정성을 개선할 수 있어, 영하 20℃까지 동결 영향을 받지 않고, 수분의 증발과 잔갈림성을 개선할 수 있다.The ethylene glycol (ethylene glycol) is preferably included 0.5 to 1.0 parts by weight with respect to 100 parts by weight of the water-soluble polymer, when added in this range can improve the stability at low temperatures, which is one of the disadvantages of the existing surface strengthening agent, It is not affected by freezing up to minus 20 ℃, and can improve the evaporation and chafing of water.
경화촉진제인 규불화소다는 물과 일정량으로 혼합하여 볼밀(Ball mill)에서 72시간정도 수분산하게 되면 ph가 5.0에서 5.5사이로 약산성을 띠고 수용성 폴리머는 약 알카리성으로 서로 만나서 결합하게 되어 수용성 폴리머의 안정성이 파괴되어, 물과 폴리머의 분리가 일어나게 되어 물의 증발이 용이해 짐으로써 경화시간이 단축되게 된다. 따라서 에멀젼 타입의 결합재의 단점인 경화시간 지연을 해결하기 위하여 수용성 폴리머 100중량부에 대하여 0.2~1.0중량부 첨가되는 것이 바람직하다. 하지만, 과도한 양의 규불화소다가 혼입되면 수용성 폴리머 주위에 쇼킹(shocking)현상이 발생되어 품질저하의 원인이 됨으로 상기 첨가량이 바람직하다. 또한 경화촉진제로서는 염화칼슘 1중량%, 비이온성계면활성제 4중량%, 물 95중량%로 제조하여 사용 할 수도 있다.Sodium fluoride, a curing accelerator, is mixed with water in a certain amount and dispersed for about 72 hours in a ball mill. The pH is 5.0 to 5.5. The pH is weakly acidic, and the water-soluble polymers are weakly alkaline. This breaks up, causing separation of water and polymer, which facilitates evaporation of water, thereby shortening the curing time. Therefore, in order to solve the curing time delay, which is a disadvantage of the emulsion-type binder, it is preferable to add 0.2 to 1.0 parts by weight based on 100 parts by weight of the water-soluble polymer. However, when the excessive amount of sodium fluoride is mixed, shocking occurs around the water-soluble polymer, which causes deterioration of the quality, and thus the addition amount is preferable. In addition, the curing accelerator may be prepared by using 1% by weight of calcium chloride, 4% by weight of nonionic surfactant, and 95% by weight of water.
안료는 도로 상에서 식별이 용이하도록 첨가되며 상기 함량으로 첨가할 때 보다 선명한 색상으로 식별이 용이하고 색상의 지속성이 향상될 수 있다. 안료는 당 업계에서 통상적으로 사용되는 종류가 사용될 수 있다.Pigments are added to facilitate identification on the road, and when added in the above contents, the pigments are easier to identify with more vivid colors and the color persistence can be improved. The pigment may be used a kind commonly used in the art.
상기 탄성폼은 폐폴리에틸렌 테레프탈레이트폼과 폐우레탄폼이 중량비로 20~40 : 60~80 혼합되어 이루어질 수 있다. 여기서 폐폴리에틸렌 테레프탈레이트폼은 1~2mm의 입도를 갖고 폐우레탄폼은 2~3mm의 입도로 이루어지는 것이 바람직하다. 상기 범위 이상의 입도로 구성된 탄성폼은 사람이 보행시 느끼는 충격을 최소화하고 기존의 고무블럭과는 다르게 피로감을 덜 느끼며 수차례 실험한 결과 제시한 중량비로 혼합하였을 경우에 기계화 시공이 가능하다. The elastic foam may be made by mixing waste polyethylene terephthalate foam and waste urethane foam in a weight ratio of 20 to 40: 60 to 80.

<시험예 2> 인장강도, 접착강도 및 신장률 시험Test Example 2 Tensile Strength, Adhesive Strength, and Elongation Test
본 발명에 따라 실시예 1 내지 6에서 제조된 탄성체 조성물과 비교예 1, 2에서 제조한 탄성체 조성물의 특성을 비교하기 위하여, 상기 시험예 1에서 제조한 각각의 공시체를 대상으로 KS F 4919(시멘트 혼입 폴리머계 방수재)에 준하여 인장강도 및 접착강도 시험을 수행하였고, 그 결과를 하기 표 1에 나타내었다. In order to compare the properties of the elastomer compositions prepared in Examples 1 to 6 and the elastomer compositions prepared in Comparative Examples 1 and 2 according to the present invention, each specimen prepared in Test Example 1 was subjected to KS F 4919 (cement). Tensile strength and adhesive strength tests were performed in accordance with the polymer-based waterproofing material), and the results are shown in Table 1 below.
또한, KS F 4919(시멘트 혼입 폴리머계 방수재)에 준하여 공시체의 신장률을 측정하였고, 그 결과를 하기 표 2에 나타내었다.In addition, the elongation of the specimen was measured according to KS F 4919 (cement mixed polymer-based waterproofing material), and the results are shown in Table 2 below.
[표 1]TABLE 1
[표 2]TABLE 2
상기 표 1에 나타난 바와 같이, 본 발명에서 제조한 탄성체 조성물(실시예 1내지 6)은 인장강도 및 접착강도가 비교예 1 및 2에서 제조한 탄성체 조성물보다 우수하였다. 또한, 상기 실시예 1내지 6에서 제조한 탄성체 조성물의 신율 역시 비교예의 탄성바닥재와 비교하여 높았다. As shown in Table 1, the elastic composition (Examples 1 to 6) prepared in the present invention was superior to the elastic composition prepared in Comparative Examples 1 and 2 tensile strength and adhesive strength. In addition, the elongation of the elastomer composition prepared in Examples 1 to 6 was also higher than that of the elastic flooring material of the comparative example.
실시예와 비교예의 차이는 실시예에 사용되는 수용성 폴리머는 기타 혼화재료를 사용하여 그 물성을 증대시킨 것이며 개질된 수용성 폴리머에 따라 시공이 가능하게 탄성체 폼을 적정하게 배합한 것임. 또한 탄산칼슘에 따라 고무칩이 시공장비 내에서 엉겨붙는 현상을 최소화 하기위해 적정사용량을 사용한 것임. 탄산칼슘이 과다하게 되면 강도특성이 낮아지며 탄성특성이 없어지고 탄산칼슘을 소량 사용하게 되면 시공장비 내에서 고무칩이 뭉치는 현상이 생겨 장비내에서 막힘 현상이 발생하고 수용성 폴리머가 경화후 잔갈림 현상이 생길 수 있다.The difference between the Example and the Comparative Example is that the water-soluble polymer used in the Example is an increase in the physical properties using other miscible materials, and the elastomer foam is properly formulated to enable construction according to the modified water-soluble polymer. In addition, the optimum amount is used to minimize the crushing of rubber chips in the construction equipment depending on calcium carbonate. Excessive calcium carbonate leads to low strength properties, no elastic properties, and a small amount of calcium carbonate causes rubber chips to agglomerate in the construction equipment, causing blockage in the equipment, and cracking after water-soluble polymer hardens. This can happen.
즉, 본 발명에서 제조한 탄성바닥재가 비교예에서 제조한 탄성바닥재와 비교하여 강도 면에서 월등히 우수하며, 부착력이 높아 노면으로부터의 탈리 현상을 최소화 할 수 있음을 확인할 수 있었다.In other words, it was confirmed that the elastic flooring material prepared in the present invention was superior in strength in comparison with the elastic flooring material prepared in Comparative Example, and the adhesion was high, thereby minimizing the detachment phenomenon from the road surface.
