실시예 및 비교예Examples and Comparative Examples

실시예 1~6Examples 1-6

용융흐름지수, 비닐아세테이트 함량, 비닐알코올의 함량이 표 1에 나타낸 바대로 다른 각각의 수지(EVA, EVOH 수지, EVMH 수지)를 덤블러 믹서에 넣고 혼합한 후, 이를 싱글 압출기를 이용하여 용융 혼합시켰다. 이들 수지를 다시 압출코팅기에 넣고, 코팅필름 성형후 이들의 필름표면(가로×세로=15×30cm)에 가로×세로=5×10cm 옵셋인쇄를 하였다.Melt flow index, vinyl acetate content, and vinyl alcohol content, as shown in Table 1, was mixed with each other resin (EVA, EVOH resin, EVMH resin) into the mixer mixer and melt mixed using a single extruder I was. These resins were placed in an extrusion coating machine again, and after coating film molding, offset printing was performed on the surface (vertical x vertical = 15 x 30 cm) of the horizontal x vertical = 5 x 10 cm.

상기와 같이 제조된 인쇄층에 폴리에스테르 부직포(용융흐름지수 30g/10분, 중량 100g/㎡)로 된 지지층을 열접착하여 벽지를 제조하였다.The wallpaper was manufactured by thermally bonding a support layer made of a polyester nonwoven fabric (melt flow index 30 g / 10 min, weight 100 g / m 2) to the printed layer prepared as described above.

비교예 1Comparative Example 1

인쇄층 수지 조성물로서 비닐아세테이트의 함량이 20중량%, 용융흐름지수가 2g/10분인 에틸렌 비닐아세테이트 수지를 단독으로 사용한 것을 제외하고는 실시예와 동일하게 하여 벽지를 제조하였다.A wallpaper was prepared in the same manner as in the example except that the ethylene vinyl acetate resin having a vinyl acetate content of 20 wt% and a melt flow index of 2 g / 10 minutes was used as the printing layer resin composition.

인쇄성 시험Printability test

상기 실시예 1~6 및 비교예 1에서 제조된 벽지에 대하여, ASTM D1876에 제시된 T 박리(peel) 테스트를 하여, 잔존하는 인쇄표면의 넓이를 측정하여 인쇄성을 상대 비교하였다. The wallpaper prepared in Examples 1 to 6 and Comparative Example 1 was subjected to the T peel test shown in ASTM D1876, and the area of the remaining print surface was measured to compare the printability.

그리고, 에틸렌 비닐아세테이트 수지를 단독으로 사용한 비교예 1의 필름의 잔존 인쇄 면적을 100으로 하고, 이것과의 면적비를 비교하여 인쇄성(인쇄강도)을 비교하여, 그 결과를 하기 표 1에 나타내었다.Then, the remaining print area of the film of Comparative Example 1 using ethylene vinyl acetate resin alone was 100, and compared with the area ratio thereof, printability (print strength) was compared, and the results are shown in Table 1 below. .

Figure 112005052228941-pat00001
Figure 112005052228941-pat00001

상기 표 1로부터 알 수 있는 바와 같이, EVA 단독수지보다 EVA 수지, EVOH 수지, EVMH 수지를 혼합하여 이루어진 인쇄층을 사용하여 제조한 실시예의 벽지의 인쇄성이 우수하였다.As can be seen from Table 1, the printability of the wallpaper of the example produced using a printing layer made by mixing EVA resin, EVOH resin, EVMH resin than the EVA alone resin.

포름알데히드 방출시험Formaldehyde Release Test

상기 실시예 1~6에서 제조된 각 벽지에 대하여 KS F3111에 따라 포름알데히드 방출량을 측정하였다. 측정 결과, 실시예 1~6의 벽지의 포름알데히드 방출량은 모두 0mg/㎡h이었으며, 이는 환경부 친환경건축자재 품질 인증제 규정의 크로바 5개(0.03㎎/㎡h 미만)에 해당하는 것이었다.For each wallpaper prepared in Examples 1 to 6, the amount of formaldehyde emission was measured according to KS F3111. As a result of the measurement, the formaldehyde emission of the wallpaper of Examples 1 to 6 were all 0 mg / m 2 h, which corresponds to 5 claws (less than 0.03 mg / m 2 h) of the Ministry of Environment's environmentally friendly construction materials quality certification.

이상에서 알 수 있는 바와 같이, 본 발명에 따른 벽지는, 포름알데히드와 같은 유해한 휘발성 유기화합물 및 내분비계 장애물질을 방출하지 않아 새집 증후군을 감소시키기 위한 벽지로서 적합하다. 또한, 본 발명에 따른 벽지는 가소제 및 염소원소를 함유하지 않기 때문에, 종래 PVC계와 달리 연소시 염화수소가스 및 다이옥신을 발생시키지 않으며, 동시에 인쇄성을 향상시킴으로써 벽지의 외관을 수려하게 하는 효과를 갖는다.As can be seen from above, the wallpaper according to the present invention is suitable as a wallpaper for reducing the sick house syndrome by not releasing harmful volatile organic compounds such as formaldehyde and endocrine disruptors. In addition, since the wallpaper according to the present invention does not contain a plasticizer and a chlorine element, unlike the conventional PVC system, it does not generate hydrogen chloride gas and dioxins during combustion, and at the same time has an effect of enhancing the printability to enhance the appearance of the wallpaper. .
