The present invention relates to an agricultural vinyl chloride resin film, and more particularly to an agricultural vinyl chloride resin film that has improved adhesion resistance between adjacent films in the overlapping portion, that is, blocking property. BACKGROUND ART In recent years, with the aim of increasing the added value of agricultural products, facility cultivation such as greenhouse cultivation and tunnel cultivation has been actively carried out. As covering materials used for greenhouse cultivation and tunnel cultivation, films of synthetic resins such as vinyl chloride resin, polyethylene, ethylene-vinyl acetate copolymer, and polyethylene terephthalate are used. Among them, agricultural soft vinyl chloride resin films are currently the most widely used because they have overall superior physical properties such as weather resistance, transparency, heat retention, and strength compared to other synthetic resin films. Agricultural soft vinyl chloride resin films containing plasticizers have various desirable physical properties as mentioned above, but on the other hand, when films overlap, they tend to adhere to each other at the overlapped portions. (hereinafter referred to as "stickiness") is large, and this tendency is particularly strong when water droplets adhere and dry. As a result, not only is the work efficiency reduced when spreading the film on greenhouses or tunnels or bonding the film using high-frequency adhesive, but also
There are drawbacks such as reduced workability when rolling up or pulling the film for ventilation in a house or tunnel. Many techniques have been proposed to reduce the tackiness of agricultural soft vinyl chloride resin films, but none of them have a sufficient tackiness-reducing effect (hereinafter referred to as "non-blocking effect"). Also, recently, in Japanese Patent Application Laid-Open No. 58-69240, N,N'-dioleyladipamide, N,N'-dioleyladipamide,
An agricultural vinyl chloride resin film containing at least one of N,N'-distearyl adipamide and ethylene bislauryl amide has been proposed, but even this film does not allow for ventilation during ventilation. The tackiness (hereinafter referred to as ``drip-proof blocking'') of the material is improved to some extent, but the tackiness during spreading or high-frequency bonding (hereinafter referred to as ``original fabric blocking'') is not improved and is unsatisfactory. Therefore, the present inventors conducted extensive research in search of a soft vinyl chloride resin film for agricultural use with further improved non-blocking effects.As a result, we found that a new N, N,
The vinyl chloride resin film obtained by blending a specific amount of N'-distearyl terephthalic acid amide and/or N,N'-distearyl isophthalic acid amide has a significantly improved non-blocking effect, and is suitable for agricultural use. It has been found that it is suitable as a covering material. According to the present invention, N,N'-distearyl terephthalic acid amide and/or N,
There is provided an agricultural vinyl chloride resin film characterized in that N'-distearylisophthalic acid amide is blended in a range of 0.01 to 1.0 parts by weight per 100 parts by weight of vinyl chloride resin. The film of the present invention is a soft vinyl chloride resin film, and the basic composition of the resin composition constituting the film is polyvinyl chloride having a number average degree of polymerization of about 800 to about 2000, preferably about 1000 to about 1500; or a film-forming copolymer mainly composed of vinyl chloride (e.g., ethylene-vinyl chloride copolymer, vinyl acetate-vinyl chloride copolymer, vinyl chloride-halogenated olefin copolymer, or these polyvinyl chloride or chloride Other compatible resins mainly composed of vinyl copolymers (e.g. polyester resins, epoxy resins, acrylic resins, vinyl acetate resins, urethane resins,
Acrylonitrile-styrene-butadiene copolymer resin, partially saponified polyvinyl alcohol, etc.) [hereinafter collectively referred to as vinyl chloride resins], 30 to 70 parts by weight per 100 parts by weight of these vinyl chloride resins. , preferably 40 to 60 parts by weight of plasticizer; 0.05 to 7 parts by weight, preferably 1.0 to 5.0 parts by weight

It is an aromatic bisamide represented by the formula: These may be blended individually or in combination. The amount of the compound is generally
Vinyl chloride resin (contains no plasticity, etc.)
0.01 to 1.0 parts by weight per 100 parts by weight, preferably 0.05 parts by weight
It can be within the range of ~0.5 parts by weight. In addition to the above-mentioned specific aromatic bisamide, the film of the present invention may contain an appropriate amount of a conventionally known lubricant such as stearic acid, methylene bis stearylamide, ethylene bis stearyl amide, etc. The agricultural film of the present invention is produced by mixing the basic ingredients of the soft vinyl chloride resin described above, the aromatic bisamide, the lubricant, etc., in a roll type, Banbury type, Henschel type mixer or extruder. After mixing or kneading, it can be manufactured by molding into a film according to a conventional molding method such as a calendar method, a T-die method, or an inflation method. The appropriate thickness of the film in this case is generally in the range of 50 to 200 microns, preferably 50 to 150 microns. The film thus formed may be subjected to a surface treatment such as a normal dust-proof coating, if necessary. Resins suitable for dust-proof coating processing include acrylic resins, for example, any acrylic resins conventionally used for dust-proofing soft vinyl chloride resin films in the field of agricultural coating materials, such as acrylic acid or methacrylic acid. Copolymers mainly composed of esters are included, such as those disclosed in Japanese Patent Publication No. 46-28194.

You can choose as appropriate from those disclosed in Publication No. 15608, Japanese Unexamined Patent Publication No. 1392/1980, etc.
In particular, as described in Japanese Patent Publication No. 57-15608,
Mainly based on an acrylic resin obtained by copolymerizing 4 to 13% by weight of N-methylolacrylamide and 87 to 96% by weight of at least one C 1 to C 12 alkyl ester of acrylic acid or methacrylic acid. It is suitable because it has excellent dust resistance and non-blocking properties, as well as flexibility and high frequency adhesion. Among them, methyl methacrylate 35-55
Mainly based on acrylic resin obtained by copolymerization of 10-30% by weight of ethyl methacrylate, 10-25% by weight of methyl acrylate, 0-10% by weight of butylacrylate, and 4-13% by weight of N-methylolacrylamide. It is particularly preferable to
Furthermore, the above five copolymerized monomers and at least one selected from butyl methacrylate, ethyl acrylate, acrylic acid, methacrylic acid, etc.
It is also effective to copolymerize with a small amount (0.01 to 2% by weight) of a seed monomer in an appropriate combination. In order to provide a coating layer made of such an acrylic resin on the surface of the above-mentioned vinyl chloride resin film, the acrylic resin as described above is dissolved in a suitable organic solvent and used for coating, for example, in the same manner as in the usual dustproofing method. A composition is prepared and coated on the surface of a vinyl chloride resin film. In addition to the acrylic resin, the coating composition may optionally contain other materials such as cellulose acetate butitate, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyurethane, ethylene-vinyl acetate copolymer, etc. A compatible resin may be included in an amount of 40 parts by weight or less, preferably 30 parts by weight or less, more preferably 25 parts by weight or less per 100 parts by weight of the acrylic resin, and if necessary, Appropriate amounts of light stabilizers such as ultraviolet absorbers, antistatic agents, colorants, anti-blocking agents, plasticizers, etc. can also be blended. Coating with the above-mentioned coating composition can be carried out according to conventional methods, such as roll coating, knife coating, spray coating, dip coating, curtain flow coating, etc., and the thickness of the coating layer is strictly limited. However, it is generally advantageous to range from 1 to 5 microns, preferably from 1 to 3 microns. The above-described agricultural film of the present invention has an excellent non-blocking effect, as is clear from the Examples described later, and can be widely used for spreading agricultural greenhouses and the like. Next, the present invention will be further explained by examples. Examples 1 to 7 and Comparative Examples 1 to 6 Basic formulation: Polychloride film (1300) 100 parts by weight Dioctyl phthalate (DOP) 45 Tricresyl phosphate (TCP) 5 parts by weight Epoxy resin stabilizer (Epicoat 828 )
2.0 parts by weight Zinc stearate 1.0 〃 Barium stearate 1.0 〃 Sorbitan monostearate 1.5 〃 The ingredients shown in Table 1 below were further blended with each component of the above basic formulation, and after stirring and mixing with a Henschel mixer for 10 minutes, The mixture was kneaded on a roll heated to 165° C., and a film with a thickness of 75 ÎŒm was obtained using an inverted L-shaped calender (Examples 1 to 6 and Comparative Examples 1 to 5). Further, the film produced as described above was coated with a dustproof coating as described below. Composition formulation for dustproof coating: Methyl methacrylate 39.0 parts by weight Ethyl methacrylate 28.0 〃 Methyl acrylate 18.0 parts by weight Butyl acrylate 10.0 〃 N-methylol acrylamide 5.0 〃 0.5 parts by weight of benzoyl peroxide and 100 parts by weight of isobutyl acetate were added to the above monomer formulation. and polymerized at 80°C for 10 hours. To 100 parts by weight of the obtained polymer solution, 20 parts by weight of cellulose acetate butyrate (1/2 second CAB) was added,
The mixture was further diluted with ethyl acetate/sec-butyl alcohol (weight ratio 1/1) to obtain a coating composition having a solid content of 20% by weight. (C) The coating composition obtained in (B) above was applied to one side of the film prepared in (A) above using a bar coater #7, and dried in a gear oven at 155±5°C for 60 seconds. The coating amount is approximately 2.0g/m 2 (approximately 2Ό thick)
Dustproof treated films were obtained (Example 7 and Comparative Example 6). The blocking value and appearance of the thus obtained film were evaluated by the following methods, and the results are shown in Table 1 below. (1) Blocking value Original film blocking value Two film samples of the following sizes were overlapped with the inner and outer surfaces of the film, and JIS-Z-

Further, after being left at room temperature at 25°C for 24 hours, the 180° peelability of the two sheets was measured using a load cell type tensile testing machine in a constant temperature room at 25°C. To measure, peel off approximately 10 cm and read the average value. Sample size: 5cm width x 20cm length Pulling speed: 200mm/min Anti-blocking value By covering the top of a water tank containing 40°C hot water with a film sample with a 30° inclination and holding it for 24 hours. After wetting the inner surface of the film, the blocking value is measured in the same manner as described above.
