한편, 상기 재유화형 분말수지는 접착 보조제 및 물성 증가제로서 수분이 건조되면, 알루미나 시멘트 및 규사 사이에 결합재(binder) 역할을 해주어 접착력 증가, 내마모성 향상, 크랙 및 박리현상 방지, 휨강도를 강화시킨다.On the other hand, when the moisture is dried as an adhesion promoter and a physical property enhancer, the re-oil type powder resin acts as a binder between alumina cement and silica sand to increase the adhesive strength, improve the abrasion resistance, prevent cracking and peeling, and enhance the bending strength.
여기서, 상기 재유화형 분말수지는 특별히 제한되지는 않으나, 바람직하게는 에틸렌 비닐아세테이트(EVA), 에틸렌 비닐 클로라이드 비닐 라우에이트를 사용한다.Here, the re-melting type powder resin is not particularly limited, but ethylene vinyl acetate (EVA) and ethylene vinyl chloride vinyl laate are preferably used.
더욱 바람직하게는 상기 재유화형 분말수지는 바잘트 산 에틸렌 비닐 에스테르(Vinyl ester of versatic acid ethylene vinyl acetate, VA/VeoVA)이다.More preferably, the rewarming powder resin is a vinyl ester of versatic acid ethylene vinyl acetate (VA / VeoVA).
이로 제한되는 것은 아니나, 바잘트 산 에틸렌 비닐 에스테르는 입경이 75㎛～85㎛이고, 비중이 0.46～0.6이며, 유리전이온도가 15～35℃인 것이 바람직하다.Although not limited thereto, it is preferable that the ethylene vinyl esters of bazaric acid have a particle diameter of 75 to 85 占 퐉, a specific gravity of 0.46 to 0.6, and a glass transition temperature of 15 to 35 占 폚.
여기서, 상기 재유화형 분말수지의 사용량은 10중량%이다.Here, the amount of the re-fusible powder resin used is 10 wt%.
특히 상기 재유화형 분말수지의 사용량이 5중량% 미만이면 기대 이상의 접착력, 내마모성 등의 물리적 물성이 나오지 않고, 15중량%를 초과하면 경화가 지연되고, 압축강도가 떨어지는 단점이 있다.Particularly, when the re-used powder resin is used in an amount of less than 5% by weight, physical properties such as adhesion and abrasion resistance are not achieved, and when it exceeds 15% by weight, curing is delayed and compression strength is lowered.
한편, 본 발명에 따른 섬유강화플라스틱 패널용 줄눈제 조성물에는 환경에 따라 물성을 조정하기 위하여 증점제 등의 혼합물을 추가할 수도 있다.In the meantime, a mixture of a thickener or the like may be added to the joint composition for a fiber-reinforced plastic panel according to the present invention in order to adjust physical properties depending on the environment.
이들의 함량은 통상의 범위 내에서 사용될 수 있으므로 특별히 제한되지는 않지만, 바람직하게는 줄눈제 조성물의 증점제는 0.1중량%를 사용할 수 있다.Their content can be used within a usual range, and therefore, although not particularly limited, it is preferable to use 0.1 weight% of the thickener of the joint composition.
또한, 본 발명에 따른 섬유강화플라스틱 패널용 줄눈제에서 내오존성을 향상시키는 Cycloaliphatic compound는 상수도 살균공정인 오존살균에서 발생하는 오존이 백시멘트를 부식시키는 것을 방지하는 역할을 하는 것으로, 화학반응으로부터 안정된 구조인 Aliphatic compound를 구형화(Cyclo)하여 백시멘트와 일체화되어 구조를 더욱 치밀하게 하여 오존으로 인한 부식을 예방한다.In addition, the cycloaliphatic compound that improves ozone resistance in the fiber-reinforced plastic panel joints according to the present invention plays a role in preventing the ozone generated in the sterilization process of the ozone, which is the water sterilization process, from corroding the white cement, Aliphatic compound, which is a structure, is coclo- lized and integrated with white cement to make the structure more dense to prevent corrosion due to ozone.
여기서, 상기 Cycloaliphatic compound의 사용량은 2중량%이다.Here, the amount of the cycloaliphatic compound used is 2% by weight.
Cycloaliphatic compound가 0.1중량% 미만인 경우에는 효과발현이 어렵고, 5중량%이상 사용시에는 비용대비 효과를 극대화시킬 수 없다.When the amount of the cycloaliphatic compound is less than 0.1% by weight, the effect is difficult to manifest, and when the amount is 5% by weight or more, the cost-effective effect can not be maximized.
다음으로, 본 발명에 따른 섬유강화플라스틱 패널용 접착 조성물의 바람직한 실시예 1을 설명한다.Next, preferred embodiment 1 of the adhesive composition for a fiber-reinforced plastic panel according to the present invention will be described.
그러나 아래의 실시예 1은 단지 본 발명을 구체적으로 설명하기 위한 것으로, 이 실시에 1에 의해 본 발명의 범위를 한정하는 것은 아님을 밝혀둔다.However, it is to be understood that the present invention is not limited to the first embodiment described below.
(실시예 1)(Example 1)
알루미나 시멘트 46.2중량%, 실리카 32.7중량%, 탄산칼슘 11중량%, 재유화형 분말수지 10중량%, 증점제 0.1중량%를 혼합하고, 여기에 물 28%를 첨가하여 3분간 혼합한 후, 섬유강화플라스틱 패널용 접착제의 실시예 1을 제조하였다.Mixed with 46.2% by weight of alumina cement , 32.7% by weight of silica, 11% by weight of calcium carbonate, 10% by weight of re-oiled powder resin and 0.1% by weight of a thickener, adding 28% Example 1 of a panel adhesive was prepared.

상기 표 1로 알 수 있는 바와 같이, 본 발명에 따른 섬유강화플라스틱 패널용 접착 조성물로서의 물성이 매우 만족함을 알 수 있었다.As can be seen from Table 1, the physical properties of the adhesive composition for a fiber-reinforced plastic panel according to the present invention are very satisfactory.
특히, 내약품성인 염산, 차아염소산, 수산화나트륨에서의 저항 물성이 우수하여, 추후 약품으로 인한 탈락 요인을 충분히 막아주는 기능을 할 수 있었다.In particular, it has excellent resistance properties in hydrochloric acid, hypochlorous acid, and sodium hydroxide, which are resistant to chemicals.
(비교예 1)(Comparative Example 1)
알루미나 시멘트 46.2중량%, 실리카 32.7중량%(재유화형 분말 수지량에 따라 유동적), 탄산칼슘 11중량%, 재유화형 분말수지 6, 8, 10, 12중량%, 증점제 0.1중량%를 혼합하고, 여기에 물 28%를 첨가하여 3분간 혼합한 후, 섬유강화플라스틱 패널용 접착제의 비교예 1을 제조하였다.Calcium aluminate cement 46.2 wt.%, Silica 32.7 wt.% (Fluid depending on the amount of re-oiled powder resin), calcium carbonate 11 wt.%, Re-oil type powder resin 6, 8, 10, 12 wt. , 28% of water was added and mixed for 3 minutes. Then, Comparative Example 1 of a fiber-reinforced plastic panel adhesive was prepared.
(실시예 2)(Example 2)
백시멘트 44.2중량%, 실리카 32.7중량%, 탄산칼슘 11중량%, 재유화형 분말수지 10중량%, 증점제 0.1중량%, Cycloaliphatic compound 2중량%를 혼합하고, 여기에 물 28%를 첨가하여 3분간 혼합한 후, 섬유강화플라스틱 패널용 줄눈제의 실시예 2를 제조하였다.A mixture of 44.2% by weight of white cement, 32.7% by weight of silica, 11% by weight of calcium carbonate, 10% by weight of re-oiled powder resin, 0.1% by weight of a thickener and 2% by weight of a cycloaliphatic compound were mixed.

상기 표 3으로 알 수 있는 바와 같이, 본 발명에 따른 섬유강화플라스틱 패널용 줄눈제의 오존 노출 후, 압축강도 변화가 거의 없음을 알 수 있다. As can be seen from the above Table 3, it can be seen that after the ozone exposure of the fiber-reinforced plastic panel joints according to the present invention, the compressive strength hardly changes.
특히 Cycloaliphatic compound가 백시멘트를 좀더 치밀화하여 오존의 침투를 막아줘서 압축강도 저하가 적음을 알 수 있다.Especially, it is shown that the cycloaliphatic compound prevents the penetration of ozone by making the white cement more densified, so that the decrease of compressive strength is small.
(비교예 2)(Comparative Example 2)
백시멘트 44.2중량%, 실리카 32.7중량%, 탄산칼슘 11중량%, 재유화형 분말수지 10중량%, 증점제 0.1중량%, Cycloaliphatic compound 0.5, 1, 2, 4중량%를 혼합하고, 여기에 물 28%를 첨가하여 3분간 혼합한 후, 섬유강화플라스틱 패널용 줄눈제의 비교예 2를 제조하였다.A mixture of 44.2% by weight of white cement, 32.7% by weight of silica, 11% by weight of calcium carbonate, 10% by weight of re-oiled powdery resin, 0.1% by weight of a thickener and 0.5% by weight of a cycloaliphatic compound, Were added and mixed for 3 minutes. Then, a jointing agent for a fiber-reinforced plastic panel was prepared.
상기 표 4로 알 수 있는 바와 같이, Cycloaliphatic compound 함량에 따른 오존에 대한 저항성이 달라지는 것을 알 수 있었다.As can be seen from Table 4, resistance to ozone varies depending on the content of the cycloaliphatic compound.
특히 4중량% 이상 첨가되어도 물성이 증가하지 않음을 알 수 있었다.In particular, even when added in an amount of 4 wt% or more, it was found that the physical properties did not increase.
이는 비용대비 사용량으로 봐서는 2중량%가 가장 효율적임을 알 수 있었다.It can be seen that 2 wt% is the most efficient in terms of cost-based use.
(비교예 3)(Comparative Example 3)
접착제인 실시예 1과 줄눈제 실시예 2를 혼합한 섬유강화플라스틱 패널용 접착 조성물을 적용하여 기존 사용방식인 줄눈을 고무흙손을 이용한 후, 시공방법과 자동 이송 및 토출기계를 활용한 섬유강화플라스틱 패널의 뒷면에 고르게 도포 후 시공한 방법을 비교예 3으로 실험하였다.The adhesive composition for a fiber-reinforced plastic panel in which the adhesive agent of Example 1 and the adhesive agent of Example 2 were mixed was used, and then the joint used as the conventional method was subjected to rubber troweling, The method of applying the coating uniformly on the back side of the panel was tested in Comparative Example 3.
상기 표 5로 알 수 있는 바와 같이 도 1에서 알 수 있듯이 접착제와 줄눈제의 공극으로 인해 접착력이 매우 떨어짐을 알 수 있었으며, 본 발명은 매우 우수한 결과를 나타냈다. As can be seen from Table 5, it can be seen from FIG. 1 that the adhesive force is very poor due to the gap between the adhesive and the joint agent, and the present invention shows very good results.
