[Industrial Application Field] The present invention relates to a vinyl chloride resin composition for use in agricultural films that has excellent weather resistance. [Prior Art and Problems to be Solved by the Invention] Vinyl chloride resins are used in large quantities as agricultural films for vinyl houses, tunnels, etc. because of their excellent transparency, strength, and economic efficiency. However, when used outdoors, vinyl chloride resins have the disadvantage that they are susceptible to so-called weather resistance deterioration, such as hardening and browning deterioration, due to the influence of sunlight, dust, oxygen, and the like. This drawback is particularly problematic in agricultural films. For this reason, conventionally, when applying vinyl chloride resin to agricultural films, organic acid metal salts, ultraviolet absorbers, antioxidants, organic phosphite esters, etc. have not been used as weather resistance improvers in the vinyl chloride resin. This is commonly done. In addition, it has also been reported that the stability of chlorine-containing resins against light and heat can be improved by blending a compound represented by the following general formula (1) or (2) (Japanese Patent Laid-Open No. 55-50043 , JP-A-53-91958, JP-A-58-76441, etc.). [However, in the above formulas (1) and (2), R 7 to R 9 are an alkyl group, an arylalkyl group, etc. ] However, these did not have sufficient weather resistance, as they turned brown after being exposed outdoors for only about one year. Therefore, there has been a demand in the agricultural industry for a vinyl chloride resin for agricultural films that has better weather resistance. Therefore, as a result of intensive research to meet such demands, the present inventors have discovered that vinyl chloride resin, plasticizer,
By blending a specific compound in addition to the compound represented by the above formula (1) or (2) into a conventionally known vinyl chloride resin composition consisting of a nonionic surfactant and an organic acid metal salt, It has been found that a vinyl chloride resin composition for agricultural film can be obtained which has extremely excellent weather resistance. The present invention was made based on this knowledge, and its object is to provide a vinyl chloride resin composition for agricultural films that has excellent weather resistance. [Means for Solving the Problems] The vinyl chloride resin composition for agricultural film according to the present invention to achieve the above object contains a vinyl chloride resin, a plasticizer, a nonionic surfactant, an organic acid metal salt, and the following. Compounds represented by the general formula [], and compounds represented by the following general formula [] and/or
Or, a compound represented by the following general formula [] is blended. [However, in the above formula, R 1 to R 6 are the same or different and are an alkyl group, an alkenyl group, a phenyl group, a tolyl group, a xylyl group, a nonylphenyl group, a benzyl group, or -(C o H 2o O) n -R 7 and here
R 7 is an alkyl group, n is an integer of 2 or 3, and m is an integer of 1 or more. ] Examples of the compound represented by the formula [ ] used in the present invention include the following compounds. The compound represented by the above formula [] is usually used in an amount of 0.1 to 10 parts by weight, preferably 1 to 6 parts by weight, per 100 parts by weight of the vinyl chloride resin, and may be used alone or in combination of two or more. May be used in combination. Next, examples of the compound represented by formula [] or formula [] include the following compounds. Compound represented by formula [] Compound represented by formula [] The compound represented by the above formula [] and the compound represented by the formula [] are used in a total amount of usually 0.01 to 5 parts by weight, preferably 0.05 to 1.0 parts by weight, based on 100 parts by weight of the vinyl chloride resin, Further, these compounds may be used alone or in combination of two or more. In addition, in normal synthesis methods, compounds of both formulas are produced in a mixture. Examples of plasticizers used in the present invention include phthalate esters such as dioctyl phthalate, dihexyl phthalate, and diisodecyl phthalate, and adipic esters such as dioctyl adipate and diisononyl adipate, which are commonly used as plasticizers for vinyl chloride resins. Various conventionally known plasticizers can be used. The nonionic surfactant in the present invention is one that is commonly blended into agricultural films,
It functions as a droplet agent as shown below. That is, when it gets cold, a so-called dew condensation phenomenon occurs in which moisture adheres to the inner wall surface of an agricultural film such as a vinyl greenhouse for greenhouse cultivation due to the difference in temperature between the inside and outside. Since the vinyl chloride resin is hydrophobic, water droplets generated by this dew condensation fall on indoor plants and hinder their growth. However, when a nonionic surfactant is blended into the film, the surface of the film becomes hydrophilic and blends well with water, allowing the condensed water droplets to flow downward along the inner wall of the film and into the ground. Because they leave, plant growth is not hindered. As the nonionic surfactant, those commonly used as droplet agents can be used, such as sorbitan monostearate, sorbitan monopalmitate, sorbitan monolaurate, sorbitan sesquistearate, and sorbitan dipalmitate. , polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan sesquistearate, polyoxyethylene sorbitan distearate, sorbitol monostearate, dipentaerythritol monopalmitate, and glycerin monostearate. Examples of the organic acid metal salt in the present invention include
Stearate of Ba, Ca, Sr, Mg or Zn,
Various conventionally known metal salts of organic acids can be used, such as laurate, octylate, behenate, oleate, benzoate, toluate, paratertiary butylbenzoate or dehydroacetate. can. In addition, in order to satisfy the basic performance in molding processing or use, the vinyl chloride resin composition for agricultural films according to the present invention may contain reinforcing agents, lubricants, anti-blocking agents, organic phosphite esters, pigments, ultraviolet rays, etc. Various conventionally known additives for vinyl chloride resins, such as absorbers, gelling agents, antioxidants, color inhibitors, and epoxy compounds, may be appropriately blended. [Examples] The present invention will be described in more detail based on Examples below, but the present invention is not limited to the Examples below, and may be practiced with appropriate modifications within the scope of the gist thereof. is possible. (Examples 1 to 11 and Comparative Examples 1 to 9) Blends having the respective compositions shown in Table 1 were kneaded with a roll at 180°C to form a film with a thickness of 0.1 mm. The obtained film was subjected to an outdoor exposure test, and the discoloration state of the film was visually observed to evaluate weather resistance. (Examples 12 to 15 and Comparative Examples 10 to 13) Blends having the respective compositions shown in Table 2 were kneaded with a roll at 180°C to form a film with a thickness of 0.1 mm. The obtained film was subjected to an exposure test outdoors, and the state of the film was visually observed to evaluate its weather resistance. (Examples 16 to 23 and Comparative Examples 14 to 17) Blends having the respective compositions shown in Table 3 were kneaded with a roll at 180°C to form a film with a thickness of 0.1 mm. The obtained film was subjected to an exposure test outdoors, and the state of the film was visually observed to evaluate its weather resistance. The weather resistance evaluation criteria shown in Tables 1, 2, and 3 are as follows. ○: No change ○△: Slight browning △: Browning areas present △ ×: Many browning areas ×: Full browning
