The base layer 10 has a structure in which a nonwoven plywood layer 11 is stacked below the glass fiber impregnation layer 1 and the glass fiber impregnation layer 1, and the surface layer 10 is formed on the glass fiber impregnation layer 1. In order, the colored adhesive layer 2, the transparent layer 3, and the surface treatment layer 4 were laminated.
본 발명에 따른 마블질감의 바닥재의 제조방법에 대한 개요는 도 1에 나타낸다. 도 1의 제조방법에 따라 제조된 도 2에 도시된 본 발명의 마블질감의 바닥재의 제조방법을 설명하면, 우선 제품의 치수안정성을 부여하는 유리섬유 함침층(1)을 제조한다. An outline of a method for producing a marble-based flooring material according to the present invention is shown in FIG. 1. Referring to the manufacturing method of the flooring of the marble texture of the present invention shown in Figure 2 manufactured according to the manufacturing method of Figure 1, first to prepare a glass fiber impregnated layer (1) to impart the dimensional stability of the product.
유리섬유 함침층(1)은 유리섬유와 같은 기재 위에 함침층의 조성물을 적정 두께로 나이프 코팅하여 형성시키고, 그 하부에 부직포를 유리섬유 함침층(1)과 합판하여 130∼210℃에서 3∼10m/min의 속도로 10∼200초간 가열한 후, 합판과 동시에 겔(gel)화시키므로써 부직포 합판층(11)을 형성시킨다. 부직포 합판층(11)을 적층하지 않을 경우, 비발포하부층(12)을 적층할 수도 있다. 부직포 적층 제품의 경우, 부직포 합판층(11)의 두께는 다양할 수 있으나 유리섬유 함침층(11)에 부직포를 합판한 후의 두께가 0.5∼1.2.mm인 것이 바람직하고, 부직포를 적층하지 않고 비발포하부층(12)을 적층할 경우, 비발포하부층(12)의 두께는 다양할 수 있으나 유리섬유 함침층(11) 하부에 비발포 하부층을 겔링한 후의 두께가 0.3∼1.0mm인 것이 바람직하다.The glass fiber impregnated layer 1 is formed by knife coating a composition of the impregnated layer on a substrate such as glass fiber to an appropriate thickness, and a nonwoven fabric is laminated with the glass fiber impregnated layer 1 at the lower portion thereof at 3 to 130 ° C. After heating for 10 to 200 seconds at a rate of 10 m / min, the nonwoven plywood layer 11 is formed by gelation simultaneously with the plywood. If the nonwoven plywood layer 11 is not laminated, the non-foaming lower layer 12 may be laminated. In the case of the nonwoven laminated product, the thickness of the nonwoven plywood layer 11 may vary, but the thickness after the nonwoven fabric is laminated to the glass fiber impregnated layer 11 is preferably 0.5 to 1.2 mm, and the nonwoven fabric is not laminated. When the foamed lower layer 12 is laminated, the thickness of the non-foamed lower layer 12 may vary, but the thickness after gelling the non-foamed lower layer below the glass fiber impregnated layer 11 is preferably 0.3 to 1.0 mm.
이때 유리섬유 함침층(1)의 조성물은, 예를 들어 중합도가 1000∼2000인 염화비닐수지 100중량부에 가소제 30∼70중량부, 안정제 1∼5중량부, 충진제 50∼200중량부와 기타 첨가제를 혼합하여 졸(sol) 상태로 만든 것이 바람직하다.At this time, the composition of the glass fiber impregnated layer (1) is, for example, 30 to 70 parts by weight of plasticizer, 1 to 5 parts by weight of stabilizer, 50 to 200 parts by weight of filler and the like to 100 parts by weight of vinyl chloride resin having a polymerization degree of 1000 to 2000. It is preferable to make the sol state by mixing the additives.
상기와 같이 유리섬유 함침층(1)의 하부에 부직포 합판층(11) 또는 비발포하부층(12)이 적층되어 이루어진 기재층(10) 위에 유색접착층(2)을 형성시키는데, 이 때 마블질감을 부여하기 위해 유색졸 A(2')와 유색졸 B(2'')를 동시에 투입한 후 0.2∼1.0mm의 두께로 나이프 코팅한다.As described above, the colored adhesive layer 2 is formed on the base layer 10 formed by laminating the nonwoven plywood layer 11 or the non-foaming lower layer 12 under the glass fiber impregnated layer 1, and at this time, To give, colored sol A (2 ') and colored sol B (2' ') are added simultaneously and knife coated to a thickness of 0.2 to 1.0 mm.
유색접착층(2)을 형성하기 위해 사용하는 유색졸 A(2')와 유색졸 B(2'')의 조성물은, 예를 들어 중합도가 1000∼2000인 염화비닐수지 100중량부에 가소제 30∼100중량부, 안정제 1∼5중량부, 안료 0.01∼10중량부와 기타 첨가제를 혼합하여 졸상태로 만든 것이 바람직하다.The composition of colored sol A (2 ') and colored sol B (2' ') used for forming the colored adhesive layer 2 is, for example, 100 parts by weight of a vinyl chloride resin having a polymerization degree of 1000 to 2000, and a plasticizer of 30 to It is preferable to mix | blend 100 weight part, 1-5 weight part of stabilizers, 0.01-10 weight part of pigments, and other additives, and to make it into a sol state.
마블질감을 균일하게 부여하기 위해서는 각각의 유색접착졸의 투입 위치가 원단의 중앙을 기준으로 좌우대칭이 되도록 해야 하고, 투입되는 배관의 크기와 졸 투입방법을 효과적으로 적용하여야 한다.In order to give the marble texture uniformly, each colored adhesive sol should be symmetrical with respect to the center of the fabric, and the size of the pipe and the sol feeding method should be effectively applied.
도 4에 도시된 바와 같이, 유색졸의 투입은 각 유색졸의 투입량 및 점도에 따라 미리 정해진 서로 다른 직경을 갖는 유색졸 A, B 투입용 배관을 통해 이루어지며, 투입된 각 유색졸은 일시적으로 뱅크(졸이 코우터 앞에서 코팅되기 바로 전에 잠시 모여있는 단계)에 잠시 머물다가, 기재층(10)으로 이루어진 바닥재 원단 위에 코팅된다. 배관을 통해 졸을 투입할 때에는, 원단의 중앙, 원단의 중앙과 좌측 끝단의 중앙 및 원단의 중앙과 우측 끝단의 중앙의 총 3군데에서 졸을 투입하는 것이 바람직하고, 균일한 마블질감을 부여하기 위해서는 라인속도(line speed)를 균일하게 유지하도록 한다. 졸 투입은 코팅두께와 라인속도를 감안하여 순간적이고 불연속적인 투입이 아닌 계속적인 투입될 수 있도록 해야 한다. 투입된 졸이 뱅크에 투입되어 섞이게 되는데, 원하는 마블질감을 내기 위해서는 투입된 졸이 많이 섞이지 않은 상태로 뱅크를 빠져나와 바닥재 원단에 코팅되어야 한다. 따라서, 뱅크에 졸이 머무는 시간이 길고, 졸 뱅크량(코우터 앞에서 코팅되기 바로 전에 잠시 모여있는 졸의 양)이 많아지면 서로 다른 점도의 두가지 졸이 많이 섞이게 되어 원하는 마블질감을 얻을 수 없으므로, 졸 뱅크량은 유색졸끼리 많이 섞이지 않은 상태에서 원하는 마블질감으로 코팅될 수 있도록 일정한 양으로 유지하는 것이 바람직하다. 즉, 라인속도와 유색졸 A, B의 투입량을 각각 균일하게 유지함으로써, 유색졸이 필요 이상으로 많이 섞이기 이전에 원단에 코팅될 수 있도록 하여야 한다.As shown in Figure 4, the addition of the color sol is made through the pipes for the color sol A, B input having a different diameter predetermined according to the amount and viscosity of each color sol, each color sol is added to the bank temporarily It stays for a while (the stage where the sol is gathered just before coating in front of the coater) and is coated on the flooring fabric made of the base layer 10. When injecting the sol through the pipe, it is preferable to inject the sol in three places: the center of the fabric, the center of the fabric and the left end, and the center of the fabric and the right end, to give a uniform marble texture. To do this, keep the line speed uniform. Sol injection should take into account the coating thickness and line speed so that it can be added continuously rather than instantaneously and discontinuously. The sol is introduced into the bank and mixed, and in order to produce the desired marble texture, the sol must be exited from the bank without being mixed and coated on the flooring fabric. Therefore, if the sol stays in the bank for a long time and the amount of sol bank (the amount of sol gathered for a while before being coated in front of the coater) increases, the two sol having different viscosities are mixed, so that the desired marble texture cannot be obtained. The amount of the sol bank is preferably maintained at a constant amount so that the colored sol can be coated with a desired marble texture without mixing a lot of colored sol. That is, by maintaining the line speed and the amount of the colored sol A and B uniformly, the colored sol should be coated on the fabric before mixing the colored sol more than necessary.
투입되는 졸의 양은 마블 정도에 따라 유색졸 A(2')와 유색졸 B(2'')를 8:2∼9.5:0.5의 비율로 투입되도록 2종의 유색졸의 점도를 고려하여 배관 크기의 조정이 필요하다. 유색졸 A에 대한 유색졸 B의 비율이 상기 비율보다 높을 경우, 제조된 바닥재의 마블질감이 혼란스럽고 지저분하여 외관상 좋지 않고, 유색졸 A에 대한 유색졸 B의 비율이 상기 비율보다 낮을 경우, 2종의 유색졸의 색상의 부분적인 혼합에 의한 마블질감의 부여효과가 미미하므로 바람직하지 않다.The amount of sol added is pipe size considering the viscosity of the two colored sol so that colored sol A (2 ') and colored sol B (2' ') are added at a ratio of 8: 2 to 9.5: 0.5. Need adjustment. When the ratio of colored sol B to colored sol A is higher than the above ratio, the marble texture of the manufactured flooring material is confusing and dirty, and the appearance is not good, and when the ratio of colored sol B to colored sol A is lower than the ratio, 2 It is not preferable because the effect of imparting marble texture by the partial mixing of the color of the colored sol of the species is insignificant.
효과적인 마블질감을 부여하기 위해, 유색졸 A(2')와 유색졸 B(2'')는 상이한 점도를 갖는 것을 사용하는 것이 바람직한데, 제품 기본 색상을 유지하는 유색졸 A(2')의 경우 4,000∼7,000cps, 마블질감을 부여하는 유색졸 B(2'')의 경우 10,000∼15,000cps의 점도를 갖는 것이 바람직하다. 상이한 점도를 갖는 유색졸 A와 유색졸 B를 사용하는 것은 졸의 유동특성을 이용하여 유동성 차이를 주므로써 마블질감을 효과적으로 부여하기 위한 것인데, 기본이 되는 기본색(유색졸 A)의 경우 점도를 저점도화하여 원단 전체에서 균일하게 코팅이 되도록 유도하면서, 포인트색(유색졸 B)의 경우 점도를 고점도화하여 유색졸 A와 혼합되어 색상이 혼색되는 현상을 최소화하고자 하는 것이다.In order to give an effective marble texture, it is preferable to use colored sol A (2 ') and colored sol B (2' ') having different viscosities. In the case of colored sol B (2 ") giving 4,000 to 7,000 cps and marble texture, it is preferable to have a viscosity of 10,000 to 15,000 cps. The use of colored sol A and colored sol B having different viscosities is to effectively give a marble texture by varying the fluidity by using the flow characteristics of the sol. In the case of the basic color (colored sol A), It is intended to minimize the phenomenon of color mixing by mixing with colored sol A by increasing the viscosity in the case of point color (colored sol B) while lowering the viscosity to induce uniform coating throughout the fabric.
상기 유색접착층(2) 위에 투명층(3)을 적층한다. 투명층(3)은 유색접착층(2) 위에 0.05∼0.5mm의 두께로 나이프 코팅하여 130∼230℃에서 3∼10m/min의 속도로 60∼240초 동안 가열하여 겔화시켜 형성시킨다. The transparent layer 3 is laminated on the colored adhesive layer 2. The transparent layer 3 is formed by gel coating on the colored adhesive layer 2 with a thickness of 0.05 to 0.5 mm and gelling by heating at 130 to 230 ° C. at a rate of 3 to 10 m / min for 60 to 240 seconds.
투명층(3)의 조성물은, 예를 들어 중합도 1000∼2000의 염화비닐수지 100중량부에 가소제 20∼60중량부, 안정제 1∼5중량부 및 기타 첨가제를 혼합하여 졸상태로 만든 것이 바람직하다. The composition of the transparent layer 3 is preferably made into a sol state by mixing 20 to 60 parts by weight of a plasticizer, 1 to 5 parts by weight of a stabilizer and other additives to 100 parts by weight of a vinyl chloride resin having a polymerization degree of 1000 to 2000, for example.
이렇게 형성된 투명층(3) 위에 표면처리층(4)을 형성시킨다. 표면처리층(4)은 자외선 경화형 폴리우레탄 도료를 투명층(3) 위에 10∼25㎛ 두께로 적층하여 3∼10m/min의 속도로 60∼300watt/in 출력의 UV 램프 3∼8개를 사용하여 경화시키므로써 형성된다.The surface treatment layer 4 is formed on the transparent layer 3 thus formed. The surface treatment layer 4 is formed by laminating a UV curable polyurethane paint on the transparent layer 3 to a thickness of 10 to 25 μm and using 3 to 8 UV lamps having a power of 60 to 300 watt / in at a speed of 3 to 10 m / min. It is formed by curing.

A system heat-resistant (foaming) stabilizer, a Cd-Ba-Zn system heat-resistant (foaming) stabilizer, an organic tin stabilizer, etc. are used, and as a filler, calcium carbonate, silica powder, etc. are used. In addition, those used as other additives include known pigments and viscosity reducing agents.
