The present invention mainly focuses on high insulation properties for electric wires and electrical parts, non-blooming properties, non-plate-out properties, non-bleed properties for general films and sheets, as well as oil resistance, non-migration, non-extraction properties, and heat resistance. This invention relates to a novel stabilized vinyl chloride resin composition with excellent aging stability. Conventionally, oil-resistant wire coatings made of plasticized polyvinyl chloride resin have been coated with polyester plasticizers,
Tribasic lead sulfate (Tribase), dibasic lead stearate (DBL), etc. are used as stabilizers. However, lead-based stabilizers pose safety and health problems, and polyvinyl chloride compositions containing both lead-based stabilizers and polyester plasticizers, especially when applied to electric wires, have a non-bleeding property due to hydrolysis. , oil extraction resistance, heat aging loss and elongation retention are reduced. In order to improve these drawbacks, the present inventors have conducted extensive research and found that by incorporating specific additives, non-bleeding properties, oil extraction resistance, heat aging loss and elongation retention, as well as non-blooming and non-blooming properties, have been achieved. A vinyl chloride resin composition with significantly improved plate-out properties and volume resistivity was discovered, and the present invention was completed. That is, the present invention provides vinyl chloride resin with (a) a fatty acid metal soap having 12 to 22 carbon atoms whose metal is barium, calcium, strontium, zinc, or aluminum, (b) a pentaerythritol compound, and (c) anhydrous hydroxide. To provide a vinyl chloride resin composition that can significantly improve volume resistivity, non-blooming property, non-bleeding property, non-plate-out property, and elongation retention by blending a powder stabilizer containing barium. Component (a) used in the present invention is at least one or two or more selected from among fatty acid metal soaps having 12 to 22 carbon atoms whose metals are barium, calcium, strontium, zinc, and aluminum. Among these, barium soap, zinc soap, or a combined barium soap-zinc soap-aluminum soap system is preferred. In particular, it is preferable to use a zinc soap produced by reacting a fatty acid with zinc oxide or a fatty acid and zinc hydroxide by a direct method, and to use a monofatty acid aluminum or a difatty acid aluminum with an aluminum soap. Further, the fatty acids having 12 to 22 carbon atoms mentioned here include lauric acid, myristic acid, palmitic acid, stearic acid, and behenic acid, and linear saturated carboxylic acids are preferable. Component (b) includes pentaerythritol, dipentaerythritol, tripentaerythritol, as well as pentaerythritol or dipentaerythritol or tripentaerythritol and amino acid, pyroglutamic acid, oxyacid, aliphatic dibasic acid, aromatic carboxylic acid. or derivatives thereof with a compound having at least one carboxyl group in the molecule, preferably an ester compound having at least one hydroxyl group in the molecule. In the present invention, the amounts of each component (a), (b), and (c) to be added are generally as follows. That is, the amount of component (a) is 0.1 to 10.0 parts by weight per 100 parts by weight of the vinyl chloride resin.
If the amount of component (a) is less than 0.1 parts by weight, there will be defects in thermal stability and processability, and if it exceeds 10.0 parts by weight, there will be defects in non-blooming and non-bleeding properties. In addition, component (b) is 0.1 to 2.0 parts by weight per 100 parts by weight of vinyl chloride resin.
Parts by weight. If the amount of this component is less than 0.1 parts by weight, there will be a drawback in thermal stability, and if it exceeds 2.0 parts by weight, there will be drawbacks in non-blooming properties, water resistance, and tensile strength. Furthermore, component (c) is contained in an amount of 0.05 parts by weight or more, preferably 0.1 to 0.1 parts by weight.
50 parts by weight. If the anhydrous barium hydroxide is less than 0.05 part by weight, there is no performance improvement effect. Vinyl chloride resin (PVC) used in the present invention
is obtained by copolymerizing a small amount of a homopolymer of vinyl chloride or a monomer that copolymerizes with the monomer, such as vinyl acetate, acrylonitrile, styrene, acrylic ester, methacrylic acid, ethylene, propylene, butylene, etc. It is a vinyl chloride polymer, and means these alone or a mixture thereof. A plasticizer is usually added to the composition of the present invention.
As such a plasticizer, a polyester plasticizer consisting of polycarboxylic acid, polyhydric alcohol, monohydric alcohol, or monohydric carboxylic acid and having a molecular weight of about 500 to 10,000 is preferable. Examples of such a plasticizer include adipic acid-1. , 3-butylene glycol-2-ethylhexanol polyester, sebacic acid-propylene glycol-2-ethylhexanol polyester, adipic acid-propylene glycol-coco fatty acid polyester, and the like. In addition, polyester plasticizers may be used with monomeric materials such as dibasic carboxylic acid dialkyl esters, tribasic carboxylic acid trialkyl esters, and tetrabasic carboxylic acid tetraalkyl esters esterified with C 4 to C 20 monohydric alcohols. There is no problem even if it is used in combination with an ester plasticizer. Plasticizer is 5.0 to 150 parts by weight for 100 parts by weight of vinyl chloride resin.
It is preferable to use within the range of parts by weight. Furthermore, the composition of the present invention contains an epoxy compound,
For example, epoxidized soybean oil, epoxidized linseed oil,
Bisphenol A type epoxy resin, bisphenol F type epoxy resin, phenol novolak type epoxy resin, cresol novolak type epoxy resin, etc. may be used in combination. The amount of the epoxy compound to be blended is generally 0.1 to 20 parts by weight per 100 parts by weight of the vinyl chloride resin. Incidentally, other organic non-metallic additives can also be used in the stabilized composition of the present invention as long as they do not impede the purpose of the present invention. Furthermore, when the composition of the present invention is used for electric wires, fillers such as clay, calcium carbonate, and talc can be used in combination. The vinyl chloride resin composition of the present invention is fully suitable for electric wires with strict standards and has excellent oil extraction resistance, so it can be used as a film or sheet having properties such as non-migration and non-extractability, such as a water-resistant sheet.
It can also be used for insulating films, insulating tapes, leather, furniture films, wallpaper, bed leather, automobile leather, home appliance packaging films, home appliance covers, and oil-resistant boots. Moreover, the electric wire referred to here refers to polyvinyl chloride resin molded products for electrical parts such as insulated electric wires, non-migration/oil-resistant electric wires, heat-resistant electric wires, cables, sheaths, and plugs. Next, the present invention will be further explained with reference to Examples and Comparative Examples. Note that parts in the examples are based on weight. Examples 1 to 4 and Comparative Examples 1 to 4 Using each raw material in Table 1, roll kneading was carried out at 170° C. for 7 minutes to obtain a vinyl chloride resin composition for covering electric wires. The resulting compositions are shown in Table 2.
