Description
본 발명은 농업용 무적성 필름에 관한 것으로서 보다 상세하게는 농업용 비닐하우스등에 사용될 수 있는 인장강도가 우수한 농업용 무적성 필름에 관한 것이다.
The present invention relates to an agricultural invincible film, and more particularly, to an agricultural invincible film having excellent tensile strength that can be used in agricultural vinyl houses and the like.
시설재배가 이루어지는 하우스 설비에 사용되는 농업용 필름은 잦은 강풍과 강설에 대하여도 내구성이 우수해야 한다. 이러한 요구에 대응하여 정부는 자연 재해 대책법 26조와 관련하여 내재해형 규격 비닐하우스, 인삼 재배 시설 설치 및 기준 활용의 편의를 위해 "원예특작 시설 내재해 기준 지정 고시" 개정안을 고시(농림부고시 제2007-64호, 2007. 9. 28)한 바 있다. 이 고시안에는 지역별 내재해 기준 적설심 및 풍속과 내재해형 규격 인정 기준을 마련하였고, 동시에 내재해형 규격 설계도 22종을 고시하였다. 상기 기준에 따르면 내재해형 시설 재배용 피복 자재는 전국 평균 최고치인 적설심 40cm, 풍속 40m/sec에 견딜 수 있어야 한다. Agricultural films used for house cultivation should have excellent durability against frequent strong winds and snowfall. In response to this request, the Government has announced an amendment to the “National Accident Standard Designation for Gardening Specialized Facilities” for the purpose of establishing a natural disaster-type plastic house and ginseng cultivation facility and utilizing the standard in accordance with Article 26 of the Natural Disaster Countermeasures Act. -64, September 28, 2007). In this draft, regional standards for snowfall, wind speed, and windfall were recognized, and at the same time, 22 types of groundbreaking design were announced. According to the above criteria, the coating material for cultivation of disaster-resistant facilities should be able to withstand 40cm of snow cover and 40m / sec of wind speed.
시설재배용 피복 자재는 기본적으로 투광성, 보온성, 무적성, 내후성, 경제성, 작업성 등 6대 선정 기준을 고려하여 제조되고 있는데, 가장 문제가 되는 것은 상기 시설재배용 피복자재의 90%가 폴리에틸렌으로 이루어져 있고 이는 소수성이기 때문에 하우스 내 습기가 내부 표면에 맺혀 물방울이 형성되는 것이 문제였다. 이러한 문제점을 개선하기 위해 무적성을 부여하는 것이 개발되었는데, 이러한 무적제는 주로 소르비탄, 글리세린 등 극성기를 갖는 다가알콜과 비극성기를 갖는 팔미트산, 스테아린산, 올레인산 등의 지방산으로 이루어지는 계면활성제로써 이를 수지에 첨가하거나 표면에 코팅하여 무적성을 발현하고 있는 실정이다. 이렇게 무적현상이 개선되면 물방울이 맺히지 않기 때문에 투명성의 개선은 물론 보온성도 증가하는 효과를 가지게 된다.Facility cultivation coating materials are basically manufactured considering 6 selection criteria such as light transmittance, heat insulation, invincibility, weather resistance, economic efficiency, and workability. The most problematic is that 90% of the facility cultivation coating materials are made of polyethylene. Since this is hydrophobic, moisture in the house forms on the inner surface, causing water droplets to form. In order to solve this problem, imparting invincibility has been developed, and this invincible agent is mainly a polyalcohol having a polar group such as sorbitan and glycerin, and a surfactant composed of fatty acids such as palmitic acid, stearic acid and oleic acid having a nonpolar group. It is added to or coated on the surface to express the invincibility. When the invincibility is improved, water droplets do not form, so the transparency and the warmth are also increased.
그러나 이러한 시설재배용 피복 원단은 폴리에틸렌이나 폴리에스테르를 소재로 한 원단이 주로 사용되고 있으며, 그 중에서도 90%이상이 폴리에틸렌이며, 국내는 0.06mm정도의 얇은 필름을 주로 사용하고 있다. 이러한 필름은 내후성 및 인장강도등의 물리적성능이 낮아 장기간 사용시 내구성이 낮은 문제가 있었다. However, the coating material for plant cultivation is mainly used fabrics made of polyethylene or polyester, more than 90% of them are polyethylene, the domestic is mainly using a thin film of about 0.06mm. Such a film has a problem of low durability when used for a long time due to low physical performance such as weather resistance and tensile strength.
시설재배용 필름에 대해 대한민국특허출원제10-1983-0004209호 "내후성 무적 폴리에틸렌 제조방법", 대한민국특허출원제10-1994-0003138호"비닐하우스용 무적필름의 제조방법 및 그 장치" 및 대한민국특허출원제10-2004-0056639호"무수말레인산의 그라프팅 반응에 의한 PE 고분자표면 개질을 통한 무적성 비닐하우스의 제조기술 개발"이 소개 되고 있으나 단순히 필름의 무적성을 향상시키는데 그 목적이 있었으며, 장기간 사용시의 내구성향상에는 기여하지 못하고 있다.Korean Patent Application No. 10-1983-0004209 "Method for manufacturing weatherproof invincible polyethylene" for facility cultivation film, Korean Patent Application No. 10-1994-0003138 "Manufacturing method and apparatus for vinyl film for vinyl house" and Korean patent application No. 10-2004-0056639 "Development of manufacturing technology of invincible vinyl house by modifying PE polymer surface by grafting maleic anhydride" was introduced, but its purpose was simply to improve the invincibility of the film. It does not contribute to the durability improvement.
또한, 대한민국특허출원제10-2002-0081235호에서는"무적 지속성이 우수한 필름용 수지조성물 및 이를 이용한 농업용 필름"을 소개하면서 고온과 저온에서 무적성 개선을 목적으로 솔비탄 모노스테아레이트와 글리세린 모노스테아레이트를 사용하고, 실리케이트를 첨가함으로써 필름의 수명을 1-3년 정도 유지시킬 수 있다고 공개된 바 있다. 그러나 상기 기술은 5년 이상의 장기 성능을 만족시키기에는 부족한 상태이고, 무적성 향상에 따른 광의 투과율, 생물 성장에 필요한 광합성 유효 파장 및 광산란율 등의 측정과 내재해에 견딜 수 있는 인장 강도와 파열 강도의 향상에 대해서는 해결방법을 제시를 하지 못하고 있다.In addition, Korean Patent Application No. 10-2002-0081235 discloses "solventan monostearate and glycerin monostearate" for the purpose of improving invincibility at high and low temperatures while introducing "resin composition for films with excellent invincibility and agricultural film using the same". It has been published that the life of the film can be maintained for 1-3 years by using a rate and adding silicate. However, the technology is not sufficient to satisfy the long-term performance of more than 5 years, and the tensile strength and the burst strength to withstand the disaster and measurement of the light transmittance due to the improvement of invincibility, the effective wavelength of photosynthesis and the light scattering rate necessary for biological growth, etc. There is no suggestion on how to improve this.
특히, 장기간동안 무적성을 지속시키기 위해서 다량의 무적성 계면활성제를 사용함으로써 광투과율 저하를 초래하였기 때문에 오히려 시설재배용 필름의 기본적인 역할을 저하시키는 문제점이 있었다.
In particular, since the use of a large amount of invincible surfactants to maintain the invincibility for a long time caused a decrease in the light transmittance, there was a problem in lowering the basic role of the film for facility cultivation.
그러므로 본 발명에서는 상기 종래 기술의 문제점을 해결하여 국내 내재해 최고 기준인 적설심 40cm,풍속 40m/sec에 맞는 물리적 특성을 우선적으로 가지며, 무적성을 향상시킴으로써 광선 투과량을 높이고, 원단 조직점에 의한 빛의 산란으로 광선을 고르게 투과시킬 수 있는 농업용 무적성 필름을 제공하는 것을 기술적 과제로 한다.
Therefore, in the present invention, by solving the problems of the prior art has a physical characteristic suitable for the highest standards of snow indwelling 40cm, wind speed 40m / sec, which is inherent in the country, to increase the light transmittance by improving the invincibility, It is a technical problem to provide an agricultural invincible film which can transmit light evenly by scattering of light.
그러므로 본 발명에 의하면, 고밀도 폴리에틸렌수지로 이루어진 플렛얀을 경사 및 위사로 사용하여 중간층을 제직하는 단계; 저밀도 폴리에틸렌 수지 92~95중량%, 자외선 차단제 5~8중량%로 이루어진 내후성 저밀도 폴리에틸렌 마스터배치를 용융하여 상기 중간층의 표면을 코팅하여 표면수지층을 형성하는 단계; 저밀도 폴리에틸렌 수지 73~84.5중량%, 고온용 무적계면활성제 10～15중량%, 저온용 무적계면활성제 5~10중량%, 나노광촉매 0.5~2중량%로 이루어진 무적성 저밀도 폴리에틸렌 마스터 배치를 용융하여 상기 중간층의 이면을 코팅하여 이면수지층을 형성하는 단계로 이루어지는 것을 특징으로 하는 인장강도가 우수한 농업용 무적성 필름의 제조방법이 제공된다.Therefore, according to the present invention, the step of weaving the intermediate layer using a flat yarn made of a high density polyethylene resin as a warp and weft; Forming a surface resin layer by melting the weather resistant low density polyethylene masterbatch made of 92 to 95% by weight of the low density polyethylene resin and 5 to 8% by weight of the sunscreen coating the surface of the intermediate layer; The low density polyethylene resin is prepared by melting an invincible low density polyethylene master batch consisting of 73-84.5% by weight of low-density surfactant, 10-15% by weight of high temperature, 5-10% by weight of low-density surfactant, and 0.5-2% by weight of nanophotocatalyst. Provided is a method for producing an invincible film for agriculture having excellent tensile strength, comprising the step of forming a backside resin layer by coating the backside of the intermediate layer.
