본 발명은 장기유적성이 우수한 농업용 직조필름에 관한 것으로서 중간층을 구성하는 원사인 플랫얀의 다양한 배열을 통해 물리적인 유적성을 증대시키는 한편, 후처리에 의해 유적성을 보다 향상시킨 것이다.The present invention relates to an agricultural weaving film having excellent long-term relics. The present invention increases physical relativity through various arrangements of flat yarns constituting an intermediate layer, and further improves relics by post-treatment.

최근 기후 온난화로 기상이변이 많이 발생되어, 농업용 하우스의 자재가 재해에 취약함으로 잦은 태풍과 폭우, 폭설로 시설하우스 농가에 년간 3천억원 정도의 막대한 피해를 주고 있다. 이러한 피해를 경감할 목적으로 각국에서는 자연 재해에 잘 견딜수 있는 장기 피복재들이 개발되고 있으며, 주로 일본에서 PO계로 불리는 필름형태인 장기 피복재와 PE 플랫얀을 사용한 직물형태인 이스라엘의 팔리그사에서 개발된 "솔라릭", 스웨덴의 루드빅 스밴손사의 "솔라우븐", 당사에서 2008년도 지역산업 기술개발 사업으로 개발되어 판매중인 "솔라텍스" 등이 있으나 직조형태의 필름이 장기 견고성 등은 우수하나 물방울이 떨어지는 단점이 개선되지 않고 있어, 신속한 장기유적성 개발이 시급한 상태이다.Due to the recent climate warming, the weather of the farmhouse has been affected by the weather, and the materials of the agricultural house are vulnerable to disasters, causing frequent typhoons, heavy rains and heavy snow. In order to alleviate these damages, countries have been developing long-term coverings that can withstand natural disasters. They have been developed in Pali, Israel, which is a type of fabric using PE flat yarn, "Solar Rick" from Sweden, "Solar Woven" from Ludwig-Vanson Company, and "Solar Tex" which is being developed and sold by our local industry technology development project in 2008. But weaving type film is excellent in long-term robustness, It is in urgent need to develop a rapid long-term relics.

Plasticculture 144호(1994/4)에서 유적성 불량은 햇빛투과량 부족으로 수확량이 60%나 손해를 본다고 발표하였을 정도로 유적성 문제는 시설농업 발전에 매우 큰 과제이다.In Plasticculture No. 144 (1994/4), the problem of relics is a major challenge for the development of agriculture in the facility, as the defectiveness of relics has announced that the loss of sunlight causes a loss of 60% of the yield.

PO계 필름의 장기 유적성 개선을 위해서 미쓰비시 계열인 미쓰비시수지어그리드림(주)의 PO계필름의 유적성 부여 기술은 1차 프라즈마 처리를 함으로써, PE의 소수성 폴리머에 친수기를 부여하고, 메타로센 LLDPE와 EVA에 계면활성제로 된 수지혼합물을 표면 코팅해서 장기 유적성을 부여하고 있으며, 10년이상 장기사용이 보장된 아사히가세이(주)의 불소 필름은 일정한 기간이 지나면 유적제를 하우스 내면에 분무해서 재코팅을 하여 장기성을 확보하고 있다.In order to improve the long-term relics of PO-based films, the technique of imparting retention properties of PO-based films of Mitsubishi Suzuki Grire Co., Ltd., which imparts hydrophilic groups to the hydrophobic polymers of PE by applying a first plasma treatment, Asynchase Co., Ltd.'s long-term use of fluorine film for 10 years or more is provided with long-term relics by coating the surface of the resin mixture with surfactant LLDPE and EVA. After a certain period of time, And the coating is repainted to secure long-term properties.

또한, 국내 농업용 필름은 유적성이 3개월 정도밖에 유지하지 못해서 항상 소비자의 불만이 재기되고 있는 형편이며, 이에 대한 연구개발이 일신화학공업(주), 태광뉴텍(주) 등에서 도포형으로 활발히 이루어지고 있으나 성과는 미약한 편이다.In addition, the domestic agricultural film can not keep its relics for only about three months, and consumer complaints have always been recovered. The research and development of this film has been actively applied by Sun Shin Kagaku Co., Ltd., Taekwang Newtech Co., But the performance is weak.

반면, PE 플랫얀을 사용한 직조필름은 보온성이나 내재해성에 있어서는 우수 한 성질을 가지고 있으나, 유적성은 PO계 필름보다 나쁘고, 소르비탄 모노스테아레이트나 폴리그리콜스테아레이트 등 계면활성제를 이용한 유적성 개선이 주류이며, 이에 대한 개발이 미흡한 실정이다. 폴리에틸렌 직조 필름에 촉매를 사용하여 친수성을 부여하는 시도도 있었으나, 친수성효과를 더욱 향상시키기 위해서는 과다의 광촉매가 필요함에 따라 광투과율이 떨어지는 단점이 있었다.On the other hand, a woven film using PE flat yarn has excellent properties in terms of heat retention and intrinsic solubility, but the remnant property is worse than that of PO-based film, and the remediation using surfactant such as sorbitan monostearate or polyglycol stearate This is the mainstream, and the development for this is insufficient. There has also been an attempt to impart hydrophilicity to a polyethylene woven film by using a catalyst, but there is a disadvantage in that the light transmittance is inferior due to the necessity of an excess photocatalyst in order to further improve the hydrophilic effect.

폴리에틸렌 직조필름은 유적성 개선을 위해서 사용되는 조제들과 마스터배치를 가지고 T-Die로 압출시켜서 코팅하므로, 점도를 낮게하고 흐름성을 좋게하기 위해서 온도를 300℃정도까지 올려서 작업하므로 사용되는 조제나 마스터배치 수지가 열에 의해서 소실되는 부분이 많아 조건 설정 개발이 어려움이 많은 실정이다.Since the polyethylene woven film is extruded and extruded with T-die with the additives and masterbatches used to improve the legibility, the temperature is raised to about 300 ° C in order to lower the viscosity and improve the flowability. There are many portions in which the master batch resin is lost due to heat, so that it is difficult to develop condition setting.

이에 친수성 유기 계면활성제로 각종 수지 필름에 친수성을 부여함으로써 유적성을 개선하여 왔으나, 주변온도의 상승으로 수분과 함께 계면활성제가 빠져나가 유적성이 장기간 유지될수 없었던 단점을 개선하기 위하여 무기 유적성 재료를 사용하였으나 농업용필름의 광투과율을 저해하는 단점이 있었다.However, in order to improve the disadvantage that the surfactant can not be maintained for a long time due to the increase of the ambient temperature due to the increase of the ambient temperature, the inorganic material But it has a disadvantage that it inhibits the light transmittance of the agricultural film.

In the weaving film of the present invention having excellent long-term relics, the synthetic resin fleece of the intermediate layer is composed of 65 to 95% by weight of a synthetic resin selected from PE, EVA, PP, PET, NYLON and PVC, 1 to 5% by weight of an ultraviolet light absorption masterbatch, 1 to 10% by weight of an ultraviolet light absorption master batch, 1 to 5% by weight of an antioxidant master batch, 1 to 5% by weight of a PE-b-PEG master batch, and 1 to 5% by weight of an inorganic bohemite master batch, By using the synthetic flat yarn manufactured by the extrusion method to have a width of 1.5 mm to 2.5 mm and a thickness of 0.05 mm to 0.09 mm, it is possible to satisfy the heat insulation, strength and relics.

본 발명의 장기유적성이 우수한 농업용 직조필름은 표면, 중간층, 이면으로 구성되어 있고 중간층을 형성하고 있는 합성수지 플랫얀은 본 발명의 농업용 직조필름의 물리적인 성능 및 내구성을 담당하고 있는 중요한 부분이고 또한, 유적성을 증대시키기 위해서 플랫얀를 제조할 때 PE, EVA, PP, PET, NYLON, PVC 중 어느 한 합성수지 65~95중량%, 첨가제로 광안정제마스타배치 1~10중량%, 자외선흡수마스타배치 1~10중량%, 산화방지제마스타배치 1~5중량%, PE-b-PEG마스타배치 1~5중량%, 무기 보헤마이트마스타배치 1~5중량%를 혼합하여 플랫얀을 제조한다.The agricultural weaving film having excellent long-term relics of the present invention is composed of a front surface, an intermediate layer and a back surface, and a synthetic resin flat yarn forming an intermediate layer is an important part responsible for the physical performance and durability of the agricultural weaving film of the present invention , 65 to 95% by weight of a synthetic resin of PE, EVA, PP, PET, NYLON or PVC, 1 to 10% by weight of a light stabilizer master batch as additives, 1 to 10% by weight of ultraviolet absorbent master batch 1 1 to 5% by weight of PE-b-PEG masterbatch and 1 to 5% by weight of inorganic boehmite masterbatch are mixed to prepare a flat yarn.

PE-b-PEG(Polyethylene―b―polyethylene glycol)는 친수성 증대 역할을 하는데, 1중량%미만에서는 무적성 개선에 문제점이 있고, 5중량%를 초과하는 경우에는 코팅시 발열현상과 태양열과 수분에 의해 누출되는 문제점이 발생한다. 무기 보헤마이트도 친수성 부여 역할을 하는데, 1중량%미만에서는 유적성 증대에 문제점이 있고, 5중량%를 초과하는 경우에는 광투과율에 문제점이 발생한다.Polyethylene-b-polyethylene glycol (PE-b-PEG) plays a role of increasing the hydrophilicity. When it is less than 1% by weight, there is a problem in improvement of inelasticity. When it exceeds 5% by weight, There is a problem that leakage occurs. The inorganic boehmite also serves as a hydrophilic property. When the content is less than 1% by weight, there is a problem in increasing the property of retention. When the content exceeds 5% by weight, a problem occurs in the light transmittance.

상기 중간층은 섬도가 상이한 합성수지 플랫얀이 교호로 배치되어 경사 또는 위사로 공급되어 제직된 것이 최종 직물을 제직하였을 때 경사 또는 위사 방향으로 섬도차이에 의한 홈이 직물표면에 형성되어 빗물이 흐를수 있는 도관역할을 할 수 있어 바람직하다. 경우에 따라 100~700데니아인 플랫얀이 1줄, 700~1500데니아인 플랫얀이 1줄로 1:1로 배열될 수 있으며, 100~700데니아인 플랫얀이 1줄, 700~1500데니아인 플랫얀이 2줄로 1:2로 배열될 수 있으며, 100~700데니아인 플랫얀이 1줄, 700~1500데니아인 플랫얀이 3줄로 1:3으로 배열될 수 있다.The intermediate layer may be formed by alternately arranging synthetic resin flat yarns having different fineness and being supplied as warp or weft yarns to form weft yarns on the fabric surface in the warp or weft direction when the final fabric is woven, So that it can serve as a conduit. In some cases, a flat yarn of 100 to 700 denier may be arranged in a line of 1: 1, a flat yarn of 700 to 1500 denier in a line, a flat yarn of 100 to 700 denier, The yarns may be arranged in 1: 2 in 2 lines, and the flat yarns in 100 to 700 denier may be arranged in 1: 3 rows and flat yarns in the range of 700 to 1500 denier in 3 rows.

The surface resin layer is composed of 75 to 97% by weight of a low density polyethylene resin, 1 to 10% by weight of a light stabilizer master batch, 1 to 10% by weight of an ultraviolet absorbent master batch and 1 to 5% by weight of an antioxidant master batch, When the amount of the light stabilizer is less than 1 wt%, the light resistance is poor. When the light stabilizer is more than 10 wt%, the problem of yellowing occurs. When the amount of the ultraviolet absorber is less than 1% by weight, sunlight shielding is poor. When the amount of the ultraviolet absorber is more than 10% by weight, yellowing occurs.

상기 표면수지층의 자외선 흡수제는 벤조페논계, 벤조트리아졸계, 살리실산에스테르계 자외선 흡수제 중 어느 하나이며, 광안정제는 HALS(Hindered Amine Light Stabilizer)계에 축합물이 부가된 광안정제이며, 산화방지제는 페놀계, 인계 및 유황계가 혼합(blend)된 산화방지제인 것이 내후성측면에서 바람직하다.The ultraviolet absorber of the surface resin layer is any one of benzophenone, benzotriazole and salicylic ester ultraviolet absorbers. The light stabilizer is a light stabilizer to which a condensate is added to a Hindered Amine Light Stabilizer (HALS) It is preferable that the antioxidant is a phenol-based, phosphorus-based, and sulfur-based blended antioxidant.

상기 이면수지층은 저밀도 폴리에틸렌 수지 65~94중량%, 광안정제마스타배치 1~10중량%,자외선흡수제마스타배치 1~10중량% 및 산화방지제마스타배치 1~5%중량%, 소르비탄마스타배치 1~5중량%, PE-b-PEG마스타배치 1~5중량%, 무기 보헤마이트마스타배치 1~5중량%로 이루어져 내후기능과 유적작용을 하게 되는데, 상기 소르비탄마스타배치와 PE-b-PEG마스타배치 및 무기보헤마이트마스타배치는 무적제로서 유적성작용부가측면에서 바람직하다. 상기 무적제마스타배치가 3중량%미만에서는 유적성성이 좋지 않은 문제가 발생하며, 15중량%를 초과하는 경우에는 광선투과성의 문제가 발생한다.Wherein the backside resin layer comprises 65 to 94% by weight of a low density polyethylene resin, 1 to 10% by weight of a light stabilizer master batch, 1 to 10% by weight of an ultraviolet absorbent master batch and 1 to 5% by weight of an antioxidant master batch, To 5% by weight of PE-b-PEG masterbatch, 1 to 5% by weight of PE-b-PEG masterbatch and 1 to 5% by weight of inorganic boehmite masterbatch, The master batch and the inorganic boehmite master batch are non-invasive and are preferred in terms of inherent action.
