[0004] As an alternative candidate for DOP, diisononyl phthalate (DINP) is actually used as a wire coating material other than DOP (for example, refer to Patent Document 2), but since DINP is also used for rubber , there is a possibility of supply tightening, so we look forward to the practical use of other plasticizers

Embodiment

[0077] Hereinafter, the present invention will be further specifically described by way of examples. It should be noted that the present invention is not limited by the following examples.

[0078] Tables 1 and 2 show examples, and Table 3 shows conventional examples and comparative examples.

[0079]

[0080] With respect to 100 parts by mass of PVC having an average degree of polymerization of 1300, a plasticizer, a silicone oil, a calcium-zinc non-lead stabilizer as a stabilizer, and calcium carbonate as a filler were mixed in the ratio shown in Tables 1-3. Then, kneading (roll temperature: 160° C., 5 minutes) and pressing (pressing temperature: 180° C., preheating for 3 minutes, pressing at 10 MPa for 2 minutes) formed a sheet with a thickness of 1 mm. It should be noted that, regarding the plasticizer, it is necessary to add 40 parts by mass or more as an amount capable of roll kneading. Therefore, in an example where the amount of terephthalate added is 10 parts by ma...

Embodiment 1

[0108] Embodiment 1 and comparative example 1 are the situation that 10 mass parts of DOTP are added, wherein, weather resistance, permeation resistance are all qualified in the embodiment 1 that adds the silicone oil of 0.1 mass part and the DIDA of 1 mass part, and does not add In Comparative Example 1 of silicone oil and DIDA, cracks were generated after the weather resistance test, and the appearance was unacceptable, so the judgment of weather resistance was unacceptable.

[0109] In addition, Examples 2 and 3 and Comparative Examples 2 and 3 are cases in which the amount of DOTP added is 40 parts by mass and 100 parts by mass, and among them, Examples 2 and 3 in which 0.1 parts by mass of silicone oil and 1 part by mass of DIDA are added As in Example 1, it was acceptable, but on the other hand, Comparative Examples 2 and 3, which did not add silicone oil and DIDA, were unacceptable in appearance as in Comparative Example 1, and in addition, the elongation retention rate ...

Abstract

The present invention provides a vinyl chloride resin composition having good weather resistance and permeable. An electric wire (10) is equipped with an insulating layer (2) comprising a vinyl chloride resin composition containing terephthalate as a plasticizer on the outer periphery of a conductor (1), and the vinyl chloride resin composition is 100 In parts by mass, 100 parts by mass or less of the above-mentioned terephthalic acid ester, 0.1 mass part or more of silicone oil, and 1 mass part or more of adipate ester are contained.

Description

technical field [0001] The present invention relates to a vinyl chloride resin composition, and an electric wire and cable using the same. Background technique [0002] Vinyl chloride resin (PVC) is a low-cost flame-retardant material, and is used as a wire covering material by adding a plasticizer to impart flexibility. [0003] As a plasticizer, di-2-ethylhexyl phthalate (DOP), which is cheap and highly compatible with PVC, is mainly used (for example, refer to Patent Document 1). The RoHS Directive specifies the danger of prohibited substances, and the future use is worrying. [0004] As an alternative candidate for DOP, diisononyl phthalate (DINP) is actually used as a wire coating material other than DOP (for example, refer to Patent Document 2), but since DINP is also used for rubber applications , there is a possibility of supply tightening, so the practical use of other plasticizers is expected. [0005] As other plasticizers, there are plasticizers having a terep...
