It is formed on the lower surface, the adhesion strength between the silicon sheet 10 is further improved.

이때, 전술한 제2연결부재(40)는 실리콘시트의 상부면 또는 하부면에 부직포층(41)을 형성하여 이루어지며, 경화제가 혼합된 실리콘을 압축기로 압축하고, 압축된 실리콘의 상부면 또는 하부면에 부직포를 적층한 후에 압착성형하여 실리콘의 내부로 부직포의 섬유가닥이 침투한 상태에서 경화하여 제조된다.At this time, the second connection member 40 is formed by forming the nonwoven fabric layer 41 on the upper surface or the lower surface of the silicon sheet, and compresses the silicon mixed with the curing agent with a compressor, the upper surface of the compressed silicon or It is produced by laminating the nonwoven fabric on the lower surface and then pressing and hardening in a state where the fiber strand of the nonwoven fabric penetrates into the silicon.

전술한 경화제는 2,5-bis(tert-butylperoxy)-2,5-dimethylhexen으로 이루어진 것을 사용하는 것이 바람직하다. The above-mentioned curing agent is preferably composed of 2,5-bis (tert-butylperoxy) -2,5-dimethylhexene.

전술한 과정을 통해 제조된 제2연결부재(40)를 건축물의 옥상에 배열할 때는, 부직포층(41)이 형성된 면이 건축물 옥상 표면의 반대방향인 상부를 향하도록 배열하는 것이 바람직한데, 제2연결부재(40) 표면 중에서 부직포층(41)이 형성되지 않은 면이 상부면을 향하도록 배열하면, 제2연결부재(40)를 구성하는 실리콘시트와 실리콘시트(10) 사이의 연접부위가 우레탄계 접착제(20)로 직접 접착되기 때문에, 시간의 경과 및 외력 등에 따른 시트 간의 박리 및 들뜸현상이 발생되기 때문이다.When arranging the second connection member 40 manufactured through the above-described process on the roof of the building, it is preferable that the surface on which the nonwoven fabric layer 41 is formed is arranged to face the upper direction opposite to the roof surface of the building. When the non-woven fabric layer 41 is not formed on the upper surface of the second connecting member 40, the joint between the silicon sheet constituting the second connecting member 40 and the silicon sheet 10 is formed. This is because the adhesive is directly adhered with the urethane-based adhesive 20, so that peeling and lifting between sheets due to the passage of time, external force, and the like occurs.

전술한 연결부재배열단계(S101)가 더 이루어지면, 아래 도 5에 나타낸 것과 같은 방수시트층이 형성되며, 이러한 방수시트층은 실리콘시트가 사용되어 방수성, 내충격성 및 내화학성이 우수하며, 실리콘시트의 표면에 형성된 부직포층으로 인해 우레탄계 접착제에 의해 견고하게 접착되어, 박리 및 들뜸현상 등이 발생하지 않을 뿐만 아니라, 제2연결부재(40)가 더 형성되어 우레탄계 접착제(20)로 접착된 실리콘시트(10) 사이의 연접부위의 접착강도 및 내 충격성은 더욱 향상된다.
If the above-described connection member arrangement step (S101) is further made, a waterproof sheet layer as shown in Figure 5 is formed, such a waterproof sheet layer is a silicone sheet is used, excellent in waterproof, impact resistance and chemical resistance, silicon The non-woven fabric layer formed on the surface of the sheet is firmly adhered by the urethane-based adhesive, which does not cause peeling or lifting, and furthermore, the second connection member 40 is further formed to be bonded to the urethane-based adhesive 20. The adhesion strength and the impact resistance of the joints between the sheets 10 are further improved.

이하에서는, 본 발명에 사용된 실리콘시트의 경화전과 경화후의 물성을 측정하여 아래 표 1에 나타내었다.Hereinafter, the physical properties of the silicone sheet used in the present invention before and after curing are shown in Table 1 below.

(단, 실리콘 99.35 중량%에 2,5-bis(tert-butylperoxy)-2,5-dimethylhexen로 이루어진 경화제를 0.65 중량% 첨가하고, 170℃의 온도에서 10분간 압축성형하고, 200℃의 온도에서 4시간 동안 오븐경화한 실리콘시트를 가로 2mm×세로 2mm의 시편으로 제조하여 측정한 결과로, CTM은 다우코닝 시험 기준이며, JIS는 일본공업규격이고, 선 수축율은 경화제의 종류, 경화온도, 성형제품의 크기와 같은 경화조건에 따라 달라질 수 있다.)
(However, 0.65% by weight of a curing agent consisting of 2,5-bis (tert-butylperoxy) -2,5-dimethylhexen was added to 99.35% by weight of silicone, and compression molding was carried out at a temperature of 170 ° C for 10 minutes, and at a temperature of 200 ° C. As a result of manufacturing the oven-cured silicone sheet for 4 hours in 2mm x 2mm specimens, CTM is based on Dow Corning test, JIS is Japanese Industrial Standard, and the line shrinkage is the type of curing agent, curing temperature, and molding. It may vary depending on the curing conditions such as the size of the product.)
