Description
本考案はフィルム製品の技術分野に関し、特に農業用光変換ハウスフィルムに関する。 The present invention relates to the technical field of film products, and more particularly to a light conversion house film for agriculture.
太陽光が地球表面に放射する波長は約２８０〜３０００nmであり、紫外光、可視光、赤外光を含む。紫外光の波長は約２８０〜３５０nm、可視光（紫、青、ブルー、緑、黄、橙、赤の７色を含む。）の波長は約４００〜８００nm、赤外光の波長は約８００〜３０００nmである。科学的研究によれば、緑色植物の光合成をするクロロフィルが主に吸収するスペクトルは４００nm-４８０nmの青紫光領域及び６００nm-６８０nmの赤橙光領域である。緑色光の植物の光合成に対する影響は大きくないが、比較的多くの紫外光は野菜に対して二面性がある。即ち、紫外光はビニルハウス及び植物の栽培に悪い影響を与える場合がある。例えば、ビニルハウスを覆うフィルムを早く老化させ、その耐用年数が短縮される。また、あるカビと細菌の繁殖が速くなり、蛾類昆虫の虫害発生率が高まる。農業の専門家によれば、異なるフィルムについて病菌の繁殖試験及び抑制試験を行った結果、波長が２８０〜３５０nmの紫外光が病菌及び灰黴菌原種菌系の成長繁殖に最も適することを見出した。 The wavelength of sunlight emitted to the earth's surface is about 280 to 3000 nm, and includes ultraviolet light, visible light, and infrared light. The wavelength of ultraviolet light is about 280 to 350 nm, the wavelength of visible light (including seven colors of purple, blue, blue, green, yellow, orange and red) is about 400 to 800 nm, and the wavelength of infrared light is about 800 to 800 nm. 3000 nm. According to scientific studies, the spectrum mainly absorbed by chlorophyll that photosynthesizes green plants is the blue-violet light region of 400 nm-480 nm and the red-orange light region of 600 nm-680 nm. Although green light does not have a significant effect on plant photosynthesis, relatively much ultraviolet light is bilateral to vegetables. That is, ultraviolet light may adversely affect the cultivation of vinyl houses and plants. For example, a film covering a vinyl house is aged quickly and its useful life is shortened. In addition, the growth of certain molds and bacteria increases, and the incidence of insect damage to mosquito insects increases. According to an agricultural expert, as a result of conducting a propagation test and a suppression test for different bacteria on different films, it was found that ultraviolet light having a wavelength of 280 to 350 nm is most suitable for the growth and reproduction of the disease bacteria and the Aspergillus oryzae species.
農業ビニルハウス被覆用プラスチックフィルムは、通常、透明或いは半透明である。地球表面に達する太陽光はプラスチックビニルハウスフィルムに入る時、一部はプラスチックフィルムにより反射され、一部はプラスチックフィルムを透過してビニルハウスに入る。農地での試験によれば、光変換フィルムを使用してビニルハウスを被覆することは、農作物の光合成を強化し、農作物の収穫を早め、及び農作物の実の品質を高めるという効果を有し、経済的利益を顕著に増加させることが実証された。 The plastic film for covering agricultural vinyl houses is usually transparent or translucent. When the sunlight reaching the earth's surface enters the plastic vinyl house film, part of it is reflected by the plastic film, and part of the sunlight passes through the plastic film and enters the vinyl house. According to field trials, the use of a light conversion film to cover a vinyl house has the effect of enhancing the photosynthesis of the crop, speeding up the harvest of the crop, and increasing the quality of the crop. It has been demonstrated to significantly increase economic benefits.
光変換剤の開発及び利用の観点から、緑色光変換をメインとすれば、光変換作用を確実に発揮することができる。現在使用されている光変換剤は、紫外光を青色光及び赤色光に変換し、或いは緑色光を赤色光に変換する機能しかないことが多い。また、光変換、防曇、流滴性能の保持時間が短く、光変換農業用フィルム全体の応用効果をうまく現すことができない。 From the viewpoint of the development and use of the light conversion agent, if the green light conversion is the main, the light conversion action can be surely exhibited. Currently used light conversion agents often have only a function of converting ultraviolet light into blue light and red light, or converting green light into red light. In addition, the retention time of light conversion, anti-fogging and droplet performance is short, and the application effect of the whole light conversion agricultural film cannot be exhibited well.
本考案は、多層構造を有し、光変換、防曇、流滴などの特性を有する材料を異なるポリエチレン層に良好に封じ込めることができ、従来の光変換剤、無滴剤、防曇剤が流出し易さ及び互いの衝突により使用効果が悪くなるという問題を解決する、農業用光変換ハウスフィルムを提供することを目的とする。 The present invention has a multilayer structure and can well contain materials having characteristics such as light conversion, anti-fogging, and droplets in different polyethylene layers. It aims at providing the light conversion house film for agriculture which solves the problem that a use effect worsens by the ease of outflow and mutual collision.
本考案の前記技術目的は以下の技術案により実現される。即ち、少なくとも２層のポリエチレン層を有し、ポリエチレンベース層及びポリエチレン中層を含み、前記ポリエチレンベース層とポリエチレン中層との間に流滴層が設けられ、前記ポリエチレン中層上に光変換層が設けられ、前記ポリエチレンベース層、光変換層、流滴層及びポリエチレン中層は共押出成形される、ことを特徴とする農業用光変換ハウスフィルム。 The technical object of the present invention is realized by the following technical solution. That is, it has at least two polyethylene layers, includes a polyethylene base layer and a polyethylene intermediate layer, a droplet layer is provided between the polyethylene base layer and the polyethylene intermediate layer, and a light conversion layer is provided on the polyethylene intermediate layer. The agricultural light conversion house film, wherein the polyethylene base layer, the light conversion layer, the droplet layer and the polyethylene intermediate layer are coextruded.
本技術案によれば、ポリエチレンベース層、光変換層、流滴層及びポリエチレン中層は共押出機により１枚のフィルムに共押出成形され、光変換、流滴性能の物質がポリエチレン層に封じ込めることによって、それらの流出が減少され、農業用フィルムの耐用年数が延長される。同時に、光変換、流滴性能の物質がポリエチレン層により離隔されることにより、互いの衝突によりハウスフィルムの使用効果が悪くなることを避ける。太陽光がハウスフィルムに照射され、紫外光、緑色光は光変換層７を通過して変換層により植物の成長に有利である青色光、赤色光に変換される。本光変換層は、有機蛍光顔料光変換剤及び希土類有機錯体光変換剤で製造されたものである。 According to this technical solution, the polyethylene base layer, the light conversion layer, the droplet layer, and the polyethylene middle layer are coextruded into a single film by a coextrusion machine, and the material of light conversion and droplet performance is contained in the polyethylene layer. Thereby reducing their spillage and extending the useful life of agricultural films. At the same time, the use effect of the house film is prevented from being deteriorated due to the collision with each other due to the separation of the material of light conversion and droplet performance by the polyethylene layer. Sunlight is applied to the house film, and ultraviolet light and green light pass through the light conversion layer 7 and are converted into blue light and red light which are advantageous for plant growth by the conversion layer. The present light conversion layer is made of an organic fluorescent pigment light conversion agent and a rare earth organic complex light conversion agent.
さらに、前記ポリエチレン中層の表面に保温層が設けられる。 Furthermore, a heat insulating layer is provided on the surface of the polyethylene middle layer.
さらに、前記ポリエチレンベース層に防曇層が設けられる。 Furthermore, an antifogging layer is provided on the polyethylene base layer.
さらに、前記保温層はハイドロタルサイト層である。 Furthermore, the heat retaining layer is a hydrotalcite layer.

さらに、前記ポリエチレン中層は、メタロセンポリエチレン、低密度ポリエチレン、線状低密度ポリエチレン、保温剤及び流滴剤を含み、それらの材料を混合して共押出成形したものである。 Furthermore, the polyethylene intermediate layer contains metallocene polyethylene, low density polyethylene, linear low density polyethylene, a heat retaining agent and a drop agent, and those materials are mixed and coextruded.
さらに、ポリエチレン外層を含み、前記ポリエチレン中層の表面に保温層が設けられ、前記ポリエチレン外層の外表面に光変換層が設けられている。 Furthermore, a polyethylene outer layer is included, a heat insulating layer is provided on the surface of the polyethylene intermediate layer, and a light conversion layer is provided on the outer surface of the polyethylene outer layer.
さらに、前記ポリエチレンベース層は、メタロセンポリエチレン、低密度ポリエチレン、線状低密度ポリエチレン、防曇剤及び流滴剤を含み、それらの材料を混合して共押出成形する。 Further, the polyethylene base layer includes metallocene polyethylene, low density polyethylene, linear low density polyethylene, antifogging agent, and dropping agent, and these materials are mixed and coextruded.
さらに、ポリエチレン外層は、メタロセンポリエチレン、低密度ポリエチレン、線状低密度ポリエチレン、光変換剤を含み、それらの材料を混合して共押出成形する。 Furthermore, the polyethylene outer layer contains metallocene polyethylene, low density polyethylene, linear low density polyethylene, and a light conversion agent, and these materials are mixed and coextruded.
本考案によれば、三層共押出により、無滴剤につれ流失しやすい光変換、防曇、流滴等の機能が階層的に実現され、共押出装置の優位性に応じて階層的、合理的に配合することにより、光変換、防曇、流滴等の特性の材料を異なるポリエチレン層に封じ込め、従来の光変換剤、無滴剤、防曇剤が流出し易く、及び互いの衝突により使用効果が悪くなるという問題を解決する。 According to the present invention, the three-layer coextrusion realizes hierarchical functions such as light conversion, anti-fogging, and droplets that are easily washed away with a drop-free agent, and is hierarchical and rational depending on the superiority of the coextrusion equipment. By blending them, materials with characteristics such as light conversion, anti-fogging, and droplets are contained in different polyethylene layers, and conventional light conversion agents, drip-free agents, anti-fogging agents are likely to flow out, and due to collision with each other Solve the problem that the use effect becomes worse.
以上のように、本考案は以下の有益的な効果がある。即ち、本ハウスフィルムは紫外光、緑色光等の植物の成長に不利である光線を植物の成長に有利である青色光、赤色光に変換するだけでなく、多層共押出技術により、光変換、防曇、流滴等の特性の材料を異なるポリエチレン層に封じ込め、従来の光変換剤、無滴剤、防曇剤が流出し易い、及び互いの衝突により使用効果が悪くなるという問題を解決する。 As described above, the present invention has the following beneficial effects.
