Form by gelling while heating for 1-2 minutes.
비발포졸을 사용한 상부층(2)은 중합도 1000~3000인 PVC 레진 100중량부 대비 1차 가소제인 DOP 30~60중량부, 2차가소제인 파라핀계 화합물 10~20중량부, 내열 안정제인 바륨-아연계화합물 2~7중량부, 기타첨가제로서 장기 저온 내열 보강을 위한 에폭시수지 1~5 중량부(두유(豆油)를 사용 혼합하여 만든 졸)을 상기 기재층(1) 위에 공지의 방법으로 0.1 ~ 0.7mm 두께로 코팅한후, 130~210℃ 오븐에서 30~180초 동안 10~50m/분의 속도로 겔링하여 만들었다.The upper layer (2) using the non-foaming sol is 30 to 60 parts by weight of the first plasticizer DOP, 10 to 20 parts by weight of the paraffinic compound as the secondary plasticizer, and barium-a as a heat stabilizer, compared to 100 parts by weight of the PVC resin having a polymerization degree of 1000 to 3000. 2 to 7 parts by weight of the linking compound, and 1 to 5 parts by weight of an epoxy resin (sol made by mixing soymilk) for the long-term low temperature heat-resistant reinforcement as another additive on the substrate layer (1) by 0.1 to After coating to a thickness of 0.7mm, it was made by gelling at a speed of 10-50m / min for 30-180 seconds in an 130 ~ 210 ℃ oven.
이 상부층(2) 위에 그라비아나 전사지를 이용하여 인쇄층(3)을 형성한다.The printing layer 3 is formed on the upper layer 2 using gravure or transfer paper.
상기 인쇄층(3) 위에 중합도 1000~3000인 PVC 레진 100중량부 대비 1차 가소제인 DOP 30~60중량부, 2차가소제인 파라핀계 화합물 10~20중량부, 내열 안정제인 바륨-아연계화합물 2~7중량부, 기타첨가제로서 장기 저온 내열 보강을 위한 에폭시수지 1~5 중량부(두유(豆油)를 사용 혼합하여 만들어진 졸)을 0.1~0.7mm 두께로 코팅한 후, 130~230℃에서 20~150초 동안 10~50m/분 속도로 투명층(4)을 형성한다.30 to 60 parts by weight of a primary plasticizer, DOP 30 to 60 parts by weight, paraffinic compound (secondary plasticizer) to 10 to 20 parts by weight, and a barium-zinc compound which is a heat stabilizer on the printed layer (3). 2 to 7 parts by weight, 1 to 5 parts by weight of epoxy resin (sol made by mixing soymilk) for long-term low temperature heat-resistant reinforcement as other additives, and then coated at 0.1 to 0.7 mm thickness at 130 to 230 The transparent layer 4 is formed at a speed of 10 to 50 m / min for 20 to 150 seconds.
상기 투명층 상부에 표면처리층을 코팅하여 경화를 함에 있어서 1차로 semi 경화를 한 후 2톤 이상의 광택 효과를 낼 수 있도록 제작된 엠보싱 롤을 사용하여 semi 경화한 표면 처리층 위에 엠보싱을 실시한 후 2차로 완전 경화를 실시함으로써 엠보부위의 광택 차이가 표면에 그대로 전이되게 하여 2톤 이상의 광택 효과를 창출할 수 있다.After coating the surface treatment layer on the transparent layer to harden it, the surface is semi-cured firstly and then embossed on the semi-cured surface treatment layer using an embossing roll made to produce a gloss effect of 2 tons or more. By performing complete curing, the gloss difference of the embossed portion can be transferred to the surface as it is, thereby creating a gloss effect of 2 tons or more.
이때 엠보싱 자체의 무늬별로 광택 효과를 달리하도록 엠보롤을 제작하는 것이 좋으며 표면 처리층의 1차 semi경화는 액이 코팅롤에 묻지 않도록 50-65% 수준이 적당하다.At this time, it is good to manufacture the embossing roll to change the gloss effect for each pattern of the embossing itself, and the first semi-curing of the surface treatment layer is 50-65% level so that the liquid does not adhere to the coating roll.
또한 섬세한 엠보를 요구하지 않을 경우에는 표면처리층 경도를 조정하여 경화한 후 엠보싱을 할 수도 있다.In addition, when the fine embossing is not required, embossing may be performed after curing by adjusting the hardness of the surface treatment layer.

After foaming for ˜180 seconds to form the backside foaming layer (7), 20 to 80 parts by weight of the primary plasticizer DOP 20 to 80 parts by weight, 2,2,4-trimethyl-1,3 to 100 parts by weight of PVC resin having a polymerization degree of 1000 to 3000 5 to 30 parts by weight of pentanediol diisobutyrate, 5 to 20 parts by weight of a paraffinic compound as a secondary plasticizer, 1 to 20 parts by weight of titanium oxide as a pigment, and a barium-zinc compound 1 as a heat stabilizer. ~ 10 parts by weight, 1 ~ 250 parts by weight of calcium bicarbonate as a filler, and 1 ~ 5 parts by weight of epoxy resin for long-term low temperature heat reinforcement After coating to a thickness of 0.5 ~ 1.0mm, and then gelled by heating at 170 ~ 210 ℃ 30 ~ 180 seconds at a rate of 10 ~ 50m / min to form a back layer (8).
상기 이면층(8)은 경우에 따라 생략할 수도 있다.The back layer 8 may be omitted in some cases.
본고안에서는 투명층 위에 표면 처리층을 실시함에 있어서 1차로 semi 경화를 한 후 2톤 이상의 광택 효과를 낼 수 있도록 제작된 엠보싱 롤을 사용하여 semi 겔링한 표면 처리층 위에 엠보싱을 실시한 후 2차로 완전 경화를 실시함으로써 엠보부위의 광택 차이가 표면에 그대로 전이됨에 따라 기존 바닥 장식재의 표면 처리층의 단일 광택 효과에서 탈피하여 표면 처리층상에 2톤 이상의 광택 효과를 부여 함으로써 보다 자연스런 광택 효과를 창출할 수 있다.In this paper, the surface treatment layer on the transparent layer is first semi-cured and then embossed on the semi-gelled surface treatment layer using an embossing roll made to produce a gloss effect of 2 tons or more. As a result, the gloss difference of the embossed portion is transferred to the surface as it is, thereby deviating from the single gloss effect of the surface treatment layer of the existing floor decoration material, thereby giving a gloss effect of 2 tons or more on the surface treatment layer, thereby creating a more natural gloss effect.
