Abstract
Description
본 발명은 통기성 및 통수성과 미끄럼 방지를 위한 타포린에 관한 것으로, 보다 상세하게는, 폴리에틸렌 재질의 직물의 일면 또는 양면에, LDPE 또는 에틸렌 초산비닐 수지와 하이드리조 디카본 아미드 또는 아조 디카본 아미드를 혼합하여 만든 수지를 압출기에 통과시켜 부분적으로 구멍이 발생되도록 하면서 코팅함으로써, 통기성 및 통수성을 확보하면서 표면 마찰력을 증대시켜 미끄럼을 방지할 수 있도록 구성한 통기성 및 통수성과 미끄럼 방지를 위한 타포린에 관한 것이다.The present invention relates to a tarpaulin for breathability, water permeability and anti-slip, and more particularly, a mixture of LDPE or ethylene vinyl acetate resin with hydride dicarbon amide or azo dicarbon amide on one or both sides of a polyethylene fabric. It is related to the tarpaulin for breathability and water permeability and anti-slip configured to pass through the extruder made by coating the resin while making a hole to generate a portion, while increasing the surface friction force while ensuring breathability and water permeability.
통상, 방수용 천막이나 보호용 덮개, 임시 천막용 원단 및 건축용 차단막 등으로 사용되는 PE 타포린은 고밀도 폴리에틸렌(High-Density Polyethylene, HDPE)필름을 연신하여 직물(woven cloth)로 만든 다음, 이 직물의 양면에 저밀도 폴리에틸렌(Low-Density Polyethylene, LDPE)수지를 적층(laminating)하여 제조한다. 도 1에는 일반적인 PE 타포린의 제조과정이 개략적으로 도시되어 있다.PE tarpaulins, which are usually used as waterproof tents, protective covers, temporary tent fabrics, and building barriers, are made of woven cloth by drawing high-density polyethylene (HDPE) films and then placed on both sides of the fabric. It is prepared by laminating low-density polyethylene (LDPE) resin. Figure 1 schematically shows the manufacturing process of a typical PE tarpaulin.
도 1을 참조하여, 일반적인 PE 타포린의 제조과정을 개략적으로 설명하면, 타포린의 심재가 되는 고밀도 폴리에틸렌 직물을 직조한 후에, 이 직물(7)을 언와인더(unwinder)(6)에 인출 가능하게 설치한 다음, 언와인더(6)에서 인출된 직물(7)을 제 1압출유닛(21)의 가압롤(9)로 이송한다. 이와 동시에, 건식 혼합기(blender mixer)(1)내에서 모터(M)의 작동으로 일정시간 동안 혼합되어 균일화된 저밀도 폴리에틸렌 혼합수지(mixed resin)(2)가 제 1압출유닛(21)의 호퍼(3)내로 공급된 다음, 압출기(4)에 의해서 용융, 혼련된다. 다음에, 다이(5)를 통과하면서 고온의 유동성 있는 필름 상태로 압출된 수지는 언와인더(6)로부터 이송된 상기 직물(7)의 일측면에 도포된 상태에서 제 1압출유닛(21)의 냉각롤(8)과 가압롤(9)사이를 지나면서, 일정한 압력으로 가압 접촉되어 코팅이 완료된다.Referring to Figure 1, the general manufacturing process of a typical PE tarpaulin, after weaving a high-density polyethylene fabric that is the core of the tarpaulin, the fabric (7) to be taken out to the unwinder (6) After installation, the fabric 7 taken out from the unwinder 6 is transferred to the pressure roll 9 of the first extrusion unit 21. At the same time, the low density polyethylene mixed resin 2 which is mixed for a predetermined time by the operation of the motor M in the dry mixer 1 and uniformized is hoppers of the first extrusion unit 21. 3) After being fed into, it is melted and kneaded by the extruder 4. Next, the resin extruded in the state of high-temperature fluid film while passing through the die 5 is applied to one side of the fabric 7 transferred from the unwinder 6 in the first extrusion unit 21. While passing between the cooling roll (8) and the pressure roll (9), the pressure is contacted at a constant pressure to complete the coating.
이 상태에서 제 2압출유닛(22)으로 이송된 다음에, 동일한 방식으로 공급된 저밀도 폴리에틸렌 혼합수지(2)가 직물(7)의 타측면에 공급되어 압축 코팅됨으로써, PE 타포린이 완성되며, 완제품(10)은 와인더(11)에 롤형태로 권취된다.After being transferred to the second extrusion unit 22 in this state, the low-density polyethylene mixed resin 2 supplied in the same manner is supplied to the other side of the fabric 7 and subjected to compression coating, thereby completing the PE tarpaulin, and the finished product. 10 is wound around the winder 11 in roll form.
이러한 PE 타포린은 양면을 동일한 재질(LDPE) 및 방법으로 도포하여 코팅하는 것으로서, 그 고유의 용도에 따라서 방수 및 통기성을 최대한 억제하는 것을 그 목적으로 하는 제품이다. 또한, PE 타포린으로 포장된 제품을 다단으로 적재할 경우에, 도포된 LDPE 재질이 갖는 특성으로 인하여 약간의 외력에 의해서 쉽게 미끄러지는 성질 때문에, 타포린으로 포장된 제품을 다단으로 적재하는 것이 어렵게 된다. 특히, 벌목한 목재를 PE 타포린으로 덮어놓게 되면, 방수에 어려움이 있고 표면이 미끄러워 작업자들이 부상당할 우려가 있으며, 동절기에 잔디구장이나 골프장의 그린 덮개용으로 사용할 경우에도 통기성 및 통수성이 낮아 겨울철 잔디보존에 좋지 않은 영향을 미친다.The PE tarpaulin is coated with both surfaces by the same material (LDPE) and method, and is a product whose purpose is to suppress the waterproofing and breathability as much as possible according to its unique use. In addition, when the product packaged with PE tarpaulin in a multi-stage, due to the properties of the applied LDPE material is easily slipped by a slight external force, it is difficult to load the product packed in tarpaulin in multiple stages. In particular, when the timber is covered with PE tarpaulin, it is difficult to waterproof and the surface is slippery, and workers may be injured, and even when used as a green cover of a grass field or golf course in winter, the breathability and water permeability are low. Bad effect on grass conservation in winter

이하, 본 발명에 따른 통기성 및 통수성과 미끄럼 방지를 위한 타포린에 대하여 상세히 설명한다.Hereinafter, the tarpaulin for breathability and water permeability and slip prevention according to the present invention will be described in detail.
종래의 타포린이 갖고 있는 특성을 살리면서, 통기성과 통수성을 부여하거나, 적재물의 미끄럼을 방지할 수 있는 타포린을 제공하기 위한 방안으로, 본 발명의 바람직한 실시예에서는 타포린의 적어도 일면에 다수의 구멍을 지니며 표면 마찰력이 증대된 코팅층을 제공하는 방안을 예시하였으며, 이를 위해서 종래의 PE 수지 대신에 아래와 같은 신규한 조성물을 사용하였다.In order to provide breathability and water permeability, or to provide a tarpaulin that can prevent the sliding of the load while utilizing the characteristics of the conventional tarpaulin, in a preferred embodiment of the present invention a plurality of holes on at least one surface of the tarpaulin To illustrate a method for providing a coating layer having an increased surface frictional force, and for this purpose, the following novel composition was used instead of the conventional PE resin.
도 2에는 본 발명에 따라 제조된 타포린이 도시되어 있다. 이것의 구성을 보면, 직물층(32)의 양면에 수지 조성물을 도포한 양면 다공 코팅층(34)을 갖는 타포린(30)으로 제조하거나 필요에 따라서는 도 3에 도시한 바와 같이 직물층(32')의 일면에만 수지 조성물을 도포한 일면 다공 코팅층(34')을 갖는 타포린(30')으로 제조할 수도 있다. 도 4에는 이들 다수의 구멍(34a)을 갖는 다공 코팅층(34)이 구비된 타포린의 표면이 도시되어 있다.2 shows a tarpaulin made in accordance with the present invention. In view of this configuration, the fabric layer 32 'is made of tarpaulin 30 having a double-sided porous coating layer 34 coated with a resin composition on both sides of the fabric layer 32, or as shown in FIG. It is also possible to produce a tarpaulin (30 ') having a one-side porous coating layer 34' coated with a resin composition only on one side of the. 4 shows the surface of a tarpaulin with a porous coating layer 34 having these multiple holes 34a.
여기에서, 통기성 및 통수성을 부여하기 위하여 본 발명에서 사용한 수지의 조성을 보면, LDPE를 주성분으로 하고, 여기에 보조성분으로서 하이드리조 디카본 아미드 또는 아조 디카본 아미드를 첨가하여 만든 다음, 이 조성물을 압출기의 호퍼에 투입하기 전에 혼합, 균일화시킨 다음, 압출기 내에서 용융, 혼련함으로써 코팅시에 타포린의 표면에 다수의 구멍이 형성되도록 하였다.Here, in the composition of the resin used in the present invention for imparting breathability and water permeability, LDPE is used as the main component, and it is made by adding hydride dicarbon amide or azo dicarbon amide as an auxiliary component, and then the composition is prepared. Mixing, homogenization, and melting and kneading in the extruder before entering the hopper of the extruder to form a number of holes in the surface of the tarpaulin during coating.
여기에서, LDPE는 압출 코팅용으로 널리 사용되는 것을 이용하면 되며, 하이드리조 디카본 아미드 또는 아조 디카본 아미드는 마스터배치의 형태로 상업화되어 있는 것을 구득하여 이용하면 된다.Here, LDPE may be used widely used for extrusion coating, hydride dicarbon amide or azo dicarbon amide may be commercially available in the form of a masterbatch.
그리고, 미끄럼 방지를 위하여 본 발명에서 사용한 수지의 조성을 보면, 에틸렌-초산비닐 수지를 주성분으로 하고, 여기에 보조성분으로서 하이드리조 디카본 아미드 또는 아조 디카본 아미드를 혼합하여 만든다. 혼합된 조성물은 상술한 바와 동일한 공정을 거쳐서 타포린의 표면에 코팅됨으로써 다수의 구멍이 형성되도록 한다.In view of the composition of the resin used in the present invention for the prevention of slipping, an ethylene-vinyl acetate resin is used as a main component, and hydride dicarbon amide or azo dicarbon amide is mixed as an auxiliary component. The mixed composition is coated on the surface of the tarpaulin through the same process as described above so that a plurality of holes are formed.
여기에서, 에틸렌-초산비닐 수지는 초산비닐의 함량이 20 내지 28중량%를 함유하는 것이 바람직하다. 바람직하게는 초산비닐의 함량이 높을수록 표면마찰력이 증대되어 미끄럼 방지를 위한 목적에는 유리하지만, 현재 상업화되어 구득가능한 수지 중에서, 미끄럼 방지를 위해 요구되는 수준과 가격 등을 고려하여 적절하게 선정하여 사용하면 된다. 그리고, 에틸렌-초산비닐 수지의 용융지수는 10 내지 20g/10분이 바람직하며, 압출 코팅의 용이성을 위해서는 상업적으로 구득가능한 제품으로 용융지수가 20g/10분을 초과하는 것이라면 보다 바람직하다.Here, the ethylene-vinyl acetate resin preferably contains 20 to 28% by weight of vinyl acetate. Preferably, the higher the content of vinyl acetate, the more the surface friction is increased, which is advantageous for the purpose of preventing slip, but from the commercially available commercially available resins, it is appropriately selected and used in consideration of the level and price required for slip prevention. Just do it. In addition, the melt index of the ethylene-vinyl acetate resin is preferably 10 to 20 g / 10 minutes, more preferably if the melt index exceeds 20 g / 10 minutes as a commercially available product for ease of extrusion coating.
본 발명에서 부분적으로 구멍을 발생시키기 위한 수지의 구체적인 조성을 보면, LDPE 또는 에틸렌-초산비닐 수지 100중량%를 주성분으로 하고, 보조성분으로서 하이드리조 디카본 아미드 또는 아조 디카본 아미드 마스터배치를 3 내지 8중량%, 바람직하게는 4 내지 7중량% 함유하는 것이 좋다. 만일, 보조성분인 하이드리조 디카본 아미드 또는 아조 디카본 아미드가 3중량%미만이면, 발생되는 구멍의 크기가 작고 수량이 너무 작아서 80%를 초과하는 면적만큼 코팅이 이루어져 통기성 및 통수성이 낮고 미끄럼 방지효과가 거의 나타나지 않으며, 보조성분의 함량이 8중량%를 초과하는 경우에는 구멍의 크기가 너무 커지게 되며, 수량이 너무 많아지게 되어 50%이상을 도포할 수 없게 된다.In the present invention, the specific composition of the resin for partially generating pores is based on 100% by weight of LDPE or ethylene-vinyl acetate resin as a main component, and a hydride dicarbon amide or azo dicarbon amide masterbatch as an auxiliary component is 3 to 8 It is preferable to contain 4% by weight, preferably 4 to 7% by weight. If the auxiliary hydride dicarbon amide or azo dicarbon amide is less than 3% by weight, the pore size is small and the quantity is so small that the coating is made in an area of more than 80% so that the breathability and water permeability are low and slippery. There is almost no protective effect, and if the content of the auxiliary component exceeds 8% by weight, the size of the hole is too large, the quantity is too large to apply more than 50%.
본 발명의 수지 조성에는 LDPE 또는 보조성분으로 예시한 하이드리조 디카본 아미드 또는 아조 디카본 아미드 이외에도, 본 발명의 통기성 및 통수성과 미끄럼 방지효과를 저하시키지 않는 범위 내에서 여러 가지 첨가제를 추가로 함유하는 것이 가능하다. 예를 들면, 자외선 안정제, 유기 또는 무기계 착색제 및 그 마스터 배치 등을 용도에 맞게 첨가할 수 있다.The resin composition of the present invention further contains various additives within the range of not impairing the breathability, water permeability, and anti-slip effect of the present invention, in addition to the hydride dicarbon amide or azo dicarbon amide exemplified as LDPE or an auxiliary component. It is possible. For example, an ultraviolet stabilizer, an organic or inorganic colorant, its masterbatch, etc. can be added according to a use.
또한, 본 발명에 예시한 각 성분들은 압출기의 호퍼에 공급하기 전에 브렌더 믹서와 같은 건식 혼합기에서 드라이 브렌드(dry blend)하여 사용하는 것이 가능하다.In addition, it is possible to use each component illustrated in the present invention by dry blending in a dry mixer such as a blender mixer before feeding to the hopper of the extruder.
상술한 조성물과 폴리에틸렌 직조물을 사용하는 타포린의 경우, 압출기를 통하여 조성물을 용융, 혼련시킴과 동시에, 직물의 양면 또는 일면에 임의 양만을 도포시키는, 일반적으로 널리 사용되고 있는 압출코팅 가공 방식에 의하여 제조한다. 이때, 압출기의 실린더 온도는 170 내지 300℃에서 다이에서 압출되는 상태에 따라서 적절하게 조절하면 되고, 이때, 다이의 온도는 270 내지 310℃의 범위에서 압출 코팅하게 된다.In the case of tarpaulin using the above-described composition and a polyethylene woven fabric, the composition is prepared by a generally used extrusion coating process in which the composition is melted and kneaded through an extruder, and at the same time, an arbitrary amount is applied to both sides or one side of the fabric. . In this case, the cylinder temperature of the extruder may be appropriately adjusted according to the state of being extruded from the die at 170 to 300 ° C, and the temperature of the die is extrusion coated in the range of 270 to 310 ° C.
이상으로 설명한 본 발명에 의하면, 타포린의 고유한 기능을 그대로 유지하면서도, 통기성과 통수성을 부여하여 동절기에 잔디구장의 덮개나 골프장의 그린덮개용으로 사용이 가능하며, 방수성을 지니면서도 미끄럼 방지기능을 부여하여 다단으로 적재해야 하는 제품의 포장용이나 벌목장에서의 목재 보호용 덮개로서 사용할 수 있는 이점이 있다.According to the present invention described above, while maintaining the unique function of the tarpaulin, while giving breathability and water permeability, it can be used for the cover of the grass field or the green cover of the golf course in winter, and it has a waterproof and anti-slip function There is an advantage that can be used as a protective cover for the packaging of wood products or timber to be stacked in multiple stages to give.
