More specifically, the present invention relates to an agricultural vinyl chloride resin film with excellent transparency that substantially blocks light of 380 r+m or less and prevents bleeding out of ultraviolet absorbers over a long period of time.

A vinyl chloride resin film is often used as a material for covering the house or tunnel because of its excellent weather resistance, transparency, heat retention, strength, etc.

現象により、透明性が低下し植物生育に支障を与える。However, in order to substantially block UV radiation, it is necessary to add a significant amount of UV absorber. When cultivating useful plants by spreading such a vinyl chloride resin film in a greenhouse, tunnel, etc., there is a drawback that the ingredients, especially the ultraviolet absorber, bleed out over time, impairing transparency. This bleed-out phenomenon occurs particularly frequently during low-temperature seasons, so in winter when the amount of solar radiation is low, the bleed-out phenomenon reduces transparency and hinders plant growth.
このような欠点を改良した技術として、特公昭62−3

As described in Publication No. 8143, one or both sides of an ultraviolet-shielding polyvinyl chloride resin film,
A method of applying a coating made of an acrylic polymer has been proposed.

If the inside of the greenhouse remains dry even if it is spread in a greenhouse, etc.,
There is a disadvantage that the bleed-out phenomenon cannot be suppressed.

だし、本発明を完成するに至ったものである。``Means for Solving the Problems'' Under such circumstances, the present inventors have devised a simple method for producing agricultural chloride that can easily prevent bleed-out over a long period of time without being affected by environmental conditions, and has excellent transparency. As a result of intensive studies aimed at providing a vinyl resin film, we found that even when a large amount of ultraviolet absorber is blended, transparency can be maintained for a long period of time by combining magnesium hydroxide and/or hydrotalcites. This is what led them to complete the present invention.

脂フィルムにある。Therefore, the gist of the present invention is that an ultraviolet absorber is blended in an amount that substantially blocks the transmission of ultraviolet rays having a wavelength of 380 nm or less, and magnesila hydroxide and/or hydrotalcites are blended. This is an agricultural vinyl chloride resin film.
以下本発明の詳細な説明する。The present invention will be explained in detail below.
本発明において塩化ビニル系樹脂とは、ポリ塩化ビニル
、塩化ビニルを主体とした他のコモノマーとの共重合体
、これらの混合物またはこれらと他重合体あるいは共重
合体との混合物をいう。In the present invention, the vinyl chloride resin refers to polyvinyl chloride, a copolymer mainly composed of vinyl chloride with other comonomers, a mixture thereof, or a mixture of these with other polymers or copolymers.
本発明において’380nm以下の波長の紫外線の透過
を実質的に阻止する」とは、譲渡、長の光を100%完
全に阻止する場合のみならず、該波長の光の透過を2%
以下まで許容する意味で使用する。In the present invention, 'substantially blocking the transmission of ultraviolet light with a wavelength of 380 nm or less' means not only completely blocking 100% of ultraviolet light with a wavelength of 380 nm or less, but also blocking the transmission of ultraviolet light with a wavelength of 2%.
It is used to mean that the following is allowed.
紫外線吸収剤の前記塩化ビニル系樹脂への配合量は、使
用する紫外線吸収剤の紫外線吸収性能及びフィルム厚さ
に応して異なるが、塩化ビニル系樹脂100重量部に対
して1.0〜5重量部の範囲とすることができる。The amount of the ultraviolet absorber added to the vinyl chloride resin varies depending on the ultraviolet absorption performance of the ultraviolet absorber used and the film thickness, but is 1.0 to 5 parts by weight per 100 parts by weight of the vinyl chloride resin. It can be a range of parts by weight.

ノアクリレート系等の紫外線吸収剤があげられる。Examples of the ultraviolet absorbent in the present invention include benzotriazole-based, hesiphenone-based, salicylic acid-based, and cyanoacrylate-based ultraviolet absorbers that are commonly used in agricultural vinyl chloride resin films.
特に、下記−数式(脅)で示されるベンゾトリアゾール
系の紫外線吸収剤は、比較的少量の使用で紫外線吸収能
が強いため好ましい。In particular, benzotriazole-based ultraviolet absorbers represented by the following formula are preferred because they have strong ultraviolet absorbing ability when used in a relatively small amount.
