the current,? ! Plastics such as vinyl chloride resin and polyethylene are widely used in the field of EIs coating. Among them, vinyl chloride resin exhibits flexibility that cannot be obtained with other plastics by adding a plasticizer, and it also has a flexibility that cannot be obtained with other plastics.
Because it has a good balance of physical and chemical properties, has good processability and colorability, and is also relatively inexpensive, it is used as a so-called soft vinyl chloride resin in a wide variety of fields such as insulated wires, cords, and cable sheaths. It is used in A typical example of this plasticizer is di-2 phthalate.
- Ethylhexyl, widely used due to its balanced performance and price. However, with wire coatings made of soft vinyl chloride resin that uses 2-ethylhexyl phthalate as a plasticizer, the plasticizer is gradually lost due to heat and oil, resulting in a decrease in the flexibility and strength of the wire coating. There's a problem. especially,
In recent years, as buildings have become more air-conditioned and heated, there is a tendency for the temperature of wire sheathing to drop even in winter, and there is a strong need for countermeasures against the effects of heat. In addition, if the above-mentioned wire coating has good flexibility in cold weather, it will become too soft in warm weather, and conversely, if it has adequate flexibility in warm weather, it will become sandy in cold weather, making it difficult to handle during construction. There is. In order to improve these drawbacks, the use of various plasticizers has been considered and studied. For example, di-2 phthalate
- Instead of ethylhexyl, diisononyl phthalate, diisodenyl phthalate, and phthalate esters of linear alcohols having 9 to 11 carbon atoms are used, and in addition to phthalate esters, trimellitic acid esters and polyester plasticizers are used. etc. is that.

When changing the plasticizer to improve the above-mentioned drawbacks of the soft vinyl chloride resin wire coating, each has its own problems in terms of performance. That is, when diisononyl phthalate is used in place of di-2-ethylhexyl phthalate, the loss of plasticizer due to heat or oil cannot be sufficiently improved. In the case of diisodecyl phthalate, the sheet flexibility at low temperatures is insufficient. Phthalate esters of linear alcohols having 9 to 11 carbon atoms have good cold resistance but tend to have low electrical insulation properties. Trimellitic acid ester is a plasticizer with extremely excellent performance, but its high price makes it difficult to use it for anything other than special purposes, and lead-based stabilizers are often used for polyester plasticizers due to their compatibility with stabilizers. This has the drawback that it is difficult to obtain a coating with good electrical insulation properties and is expensive. In addition, trimellitic acid esters and polyester plasticizers have high viscosity and tend to have poorer workability when producing vinyl chloride resin compositions than phthalic acid esters. Therefore, it is desirable to take advantage of the advantages of phthalate esters while improving their disadvantages.

As a result of repeated studies on how to improve the drawbacks of the soft vinyl chloride resin wire wave m without sacrificing the balanced performance and economic efficiency, the present inventors discovered that phthalate was added to the vinyl chloride resin as a plasticizer. It has been found that the intended purpose can be achieved by a vinyl chloride resin composition characterized by blending butyl with -2-propyl. The present invention provides a vinyl chloride resin composition characterized by blending di-2-propylheptyl phthalate with vinyl chloride resin. In the present invention, di-2-propylheptyl phthalate is an ester obtained by reacting phthalic acid or phthalic anhydride with 2-propylhebutanol. 2-Propylheptatool is produced by, for example, producing n-valeraldehyde by oxo synthesis using butene-1 as the olefin, and producing 2-propylheptabutinal by aldol condensation of n-valeraldehyde and dehydration of the product. , can be synthesized by hydrogenation reaction of this 2-propyl butynal. In the present invention, vinyl chloride resin refers to polyvinyl chloride and vinyl chloride copolymer, and vinyl chloride copolymer is mainly composed of vinyl chloride and other monomers such as ethylene, propylene, vinyl acetate, alkyl vinyl ether, acrylic ester, and methacrylate. Examples include copolymers with acid esters, etc., but the present invention is not limited to the above types of resins. In the vinyl chloride resin composition of the present invention, the blending amount of di-2-propylheptyl phthalate is preferably 40 to 80 parts by weight per 100 parts by weight of the vinyl chloride resin. If it is less than 40 parts by weight, flexibility in cold weather is insufficient, and if it exceeds 80 parts by weight, it tends to become too soft in warm weather and mechanical strength is also lowered, which is not preferable. In addition, other plasticizers can be used in combination with the vinyl chloride resin composition of the present invention, and the total amount of plasticizers, including di-2-propylheptyl phthalate, is 40 to 40 parts by weight per 100 parts by weight of the vinyl chloride resin. It is preferable to blend 80 parts by weight. Concomitant use with plasticizers other than di-2-propylheptyl phthalate is possible as long as the effects of the present invention are not impaired.
In this case, the plasticizer used in combination is not particularly limited as long as it is generally used for vinyl chloride resins, such as di-2-ethylhexyl phthalate, diisononyl phthalate, diisodecyl phthalate, trioctyl trimellitate, and adipic acid. , di-2-ethylhexyl, epoxidized soybean oil, tri(alkyl, aryl) phosphate, etc., and two or more of these may be used in combination. The vinyl chloride resin composition of the present invention includes vinyl chloride resin,
Di-2-propylheptyl phthalate and the required amount of other plasticizers, as well as stabilizers, stabilizing aids, antioxidants, lubricants, UV absorbers, toughening agents, processing aids, and fillers as required. ,
A coloring agent and the like can be added. Examples of stabilizers include lead salts such as tribasic lead sulfate, lead stearate,
Metal soap stabilizers such as calcium stearate, barium stearate, zinc stearate, calcium ricinoleate, barium laurate, organotin stabilizers such as dibutyltin dilaurate, dibutyltin maleate, dioctyltin mercaptide. etc. can be mentioned. Stabilizing aids include, for example, triphenyl phosphite, U7 acid) IJ-2-ethylhexynyl, trinonylphenyl phosphite, and other phosphite 54 M inhibitors include, for example, t -butylhydroxytoluene and dilaurylthiodipropionate. Examples of lubricants include stearic acid, stearamide, and polyethylene wax, and examples of ultraviolet absorbers include 2-(5-methyl-2-hydroxyphenyl)benzotriazole and 2-
(3-t-butyl-5-methyl-2-hydroquinophenyl)-5-chlorobenzotriazole is mentioned. As the reinforcing agent, for example, a copolymer of methacrylic acid ester, butadiene and styrene, nitrile butadiene rubber,
Examples include copolymers of ethylene and vinyl acetate. Examples of processing aids include polymethyl methacrylate. Examples of the filler include calcium carbonate and calcined resin. Examples of the coloring agent include phthalonanine blue, titanium oxide, and carbon black. The vinyl chloride resin composition of the present invention is, for example, a mixture of vinyl chloride resin and di-2-propylheptyl phthalate as described above, and can be produced using a commonly used ribbon blender or Henschel. Mixing equipment such as a mold mixer, kneading stages such as a Banbury mixer or two rolls, and even pellet manufacturing equipment can be used.
