The electric wire (10) is provided with an insulating layer (2) comprising a vinyl chloride resin composition which contains a terephthalate as a plasticizer and contains 100 parts by mass or less of the terephthalate and 0.1 part by mass or more of a silicone rubber per 100 parts by mass of a vinyl chloride resin, on the outer periphery of a conductor (1).
Description
Technical Field
The present invention relates to a vinyl chloride resin composition, and a wire and a cable using the same.
Background
Vinyl chloride resin (PVC) is a low-cost and flame-retardant material, and is used as an electric wire coating material by adding a plasticizer to impart flexibility.
As the plasticizer, di-2-ethylhexyl phthalate (DOP) which is inexpensive and highly compatible with PVC is mainly used (for example, see patent document 1), but in recent years, there is a risk that it is designated as a forbidden substance by REACH regulation and RoHS directive, and there is a concern about its use in the future.
As an alternative candidate of DOP, diisononyl phthalate (DINP) which is practically used as a wire coating material other than DOP is cited (for example, see patent document 2), but since DINP is also used for rubber applications, there is a possibility that supply shrinkage occurs, and therefore, practical use of other plasticizers is expected.
As another plasticizer, there is a plasticizer having a terephthalate structure which has compatibility with PVC equivalent to that of DOP and DINP (for example, see patent documents 3 to 4).

Detailed Description
[ vinyl chloride resin composition ]
A vinyl chloride resin composition according to an embodiment of the present invention is a vinyl chloride resin composition containing a terephthalate ester as a plasticizer, and contains 100 parts by mass or less of the terephthalate ester and 0.1 part by mass or more of a silicone rubber per 100 parts by mass of a vinyl chloride resin.
The present inventors considered that the reason why the weather resistance of terephthalate is poor is that terephthalate has a structure in which the carboxyl groups of the ester are separated, and therefore, terephthalate is likely to contact water entering from the outside, and has high hydrolyzability.
Therefore, in order to suppress deterioration of weather resistance when using terephthalate, various additives have been studied and, as a result, it has been found that weather resistance can be improved by adding silicone rubber having excellent water repellency.
On the other hand, liquid silicone oil improves weather resistance, but is difficult to be compatible with PVC and terephthalate, and causes problems such as bleeding on the surface of the composition and stickiness on the surface.
Accordingly, the present inventors have conducted studies in consideration of both weather resistance and bleeding resistance, and as a result, have found that a solid silicone rubber can achieve both of them, and have developed the vinyl chloride resin composition of the present invention.
(terephthalic acid esters)
In the vinyl chloride resin composition according to the embodiment of the present invention, the terephthalate used as the plasticizer is preferably a terephthalate having 8 to 10(C8 to C10) carbon atoms per alkyl chain. When the amount is less than C8, it is difficult to obtain the desired heat resistance. This is because the smaller the number of carbon atoms in the alkyl chain, that is, the lower the molecular weight, the more the volatilization of the plasticizer by heating is accelerated, and the vinyl chloride resin composition is cured. On the other hand, if it is C11 or more, the alcohol necessary for the ester synthesis of the plasticizer is difficult to obtain, and the cost increases, and therefore the practicability is low, and therefore, it is preferably C10 or less.
The alkyl chain of the terephthalate may have a straight chain structure or a branched chain structure, and is preferably a branched chain structure. Specifically, di-2-ethylhexyl terephthalate (DOTP) is mentioned as the C8 terephthalate, diisononyl terephthalate (DINTP) is mentioned as the C9 terephthalate, and diisodecyl terephthalate (DIDTP) is mentioned as the C10 terephthalate.
In an embodiment of the present invention, the amount of the terephthalate is 100 parts by mass or less with respect to 100 parts by mass of the vinyl chloride resin. Preferably, 10 parts by mass or more is added. The addition of the silicone rubber exerts an effect on the addition of the terephthalate, but if the amount of the terephthalate added exceeds 100 parts by mass, the plasticizer itself bleeds out and the surface becomes sticky.
(Silicone rubber)
As the silicone rubber used in the vinyl chloride resin composition according to the embodiment of the present invention, for example, dimethyl silicone rubber, methylphenyl silicone rubber, vinylphenyl silicone rubber, and methylvinylphenyl silicone rubber are preferable.
In the embodiment of the present invention, the amount of the silicone rubber added is required to be 0.1 parts by mass or more per 100 parts by mass of the vinyl chloride resin. When the amount is less than 0.1 part by mass, the desired weather resistance cannot be obtained. The amount added is preferably 5 parts by mass or less. If it exceeds 5 parts by mass, the workability tends to be problematic.
(vinyl chloride resin)
As the vinyl chloride resin, in addition to a homopolymer of vinyl chloride (i.e., polyvinyl chloride), copolymers of vinyl chloride and other copolymerizable monomers, and mixtures thereof can be cited. Examples of the monomer copolymerizable with vinyl chloride include ethyl acetate, vinylidene chloride, (meth) acrylic acid, and acrylonitrile.
As the vinyl chloride resin, a vinyl chloride resin having an average polymerization degree of 1000 to 2500 is preferably used. From the viewpoint of heat resistance, cold resistance and moldability, a vinyl chloride resin having an average polymerization degree of 1000 to 2000 is more preferable. If the polymerization degree is low, the moldability is improved, but the heat resistance and the cold resistance are lowered. On the other hand, if the polymerization degree is high, the heat resistance and the cold resistance are improved, but the moldability is poor.
As for the vinyl chloride resin, two or more vinyl chloride resins having different polymerization degrees may be mixed and used as necessary.
(other Components)
In the embodiment of the present invention, various additives such as a polymer other than PVC, an inorganic filler, a stabilizer, an antioxidant, a plasticizer, a lubricant, a colorant, an ultraviolet absorber, a light stabilizer, a crosslinking agent, and a crosslinking aid may be blended in addition to the above components as long as the effects of the present invention can be achieved.
For example, in order to improve heat resistance, cold resistance, insulation properties, and the like, other plasticizers such as phthalate esters, isophthalate esters, trimellitate esters, pyromellitate esters, and epoxidized soybean oil may be used in combination as necessary.
[ electric wire ]
An electric wire according to an embodiment of the present invention is characterized by comprising a conductor and an insulating layer covering the outer periphery of the conductor, wherein the insulating layer comprises the vinyl chloride resin composition according to the embodiment of the present invention.
Fig. 1 is a cross-sectional view schematically showing an example of an electric wire according to an embodiment of the present invention.
As shown in fig. 1, an electric wire 10 according to the present embodiment includes a conductor 1 and an insulating layer 2 covering an outer periphery of the conductor 1. The coated conductor 1 can be, for example, a conductor having an outer diameter of about 0.15 to 7mm phi. A conductor obtained by twisting a tin-plated annealed copper wire or the like can be suitably used, but is not limited thereto. The conductor 1 is not limited to one as shown in fig. 1, and may be a plurality of conductors.
The insulating layer 2 is formed of the vinyl chloride resin composition according to the embodiment of the present invention. The wire 10 can be obtained by coating the insulation layer by a molding method such as extrusion coating. If necessary, the crosslinking treatment may be performed by a method such as electron beam irradiation.
In this embodiment, the insulating layer is formed of a single layer as shown in fig. 1, but may have a multilayer structure. In this case, at least the outermost layer is formed using the vinyl chloride resin composition described above.
[ Cable ]
The cable according to an embodiment of the present invention is characterized by using the vinyl chloride resin composition according to an embodiment of the present invention as a covering material (a sheath, or an insulating layer and a sheath).
Fig. 2 is a cross-sectional view schematically showing an example of a cable according to an embodiment of the present invention.
As shown in fig. 2, the cable 20 according to the present embodiment includes three twisted wires, in which three electric wires 10 according to the above-described embodiment of the present invention in which conductors 1 are covered with insulating layers 2 are twisted together with an intervening material 3 such as paper, a pressure tape 4 wound around the outer periphery of the three twisted wires, and a sheath 5 extrusion-coated on the outer periphery of the pressure tape 4. Not limited to the three-core twisted wire, one electric wire (single core) may be used, and a multi-core twisted wire other than the three-core twisted wire may be used. The compression band 4 may be omitted or replaced by a braid.
The sheath 5 is made of the vinyl chloride resin composition according to the embodiment of the present invention. In the present embodiment, the insulating layer 2 is also composed of the vinyl chloride resin composition, but is not limited thereto, and may be composed of another resin composition for insulating layers (preferably, a halogen-free flame-retardant resin composition). The sheath 5 may be subjected to crosslinking treatment by electron beam irradiation or the like, if necessary.
In the present embodiment, the sheath may be formed of a single layer as shown in fig. 2, or may have a multilayer structure. In this case, at least the outermost layer is formed using the vinyl chloride resin composition described above.

< method for producing test piece (sheet) >
100 parts by mass of PVC having an average polymerization degree of 1300 were mixed with a plasticizer, silicone rubber, silicone oil, a calcium-zinc based non-lead stabilizer as a stabilizer, and calcium carbonate as a filler in the proportions shown in tables 1 to 3. Then, the resulting mixture was kneaded (roll temperature 160 ℃ C., 5 minutes) and pressed (pressing temperature 180 ℃ C., preheated for 3 minutes, and pressed at 10MPa for 2 minutes) to form a sheet having a thickness of 1 mm. Since the plasticizer needs to be added in an amount of 40 parts by mass or more as an amount enabling roll kneading, 30 parts by mass of DINP (diisononyl phthalate) was mixed in an example in which the amount of the terephthalate is 10 parts by mass.

< test method >
The weather resistance was evaluated by a metal halide lamp weather resistance acceleration tester M6T manufactured by SUGA tester, irradiation was performed under conditions of sample surface irradiance of 1.5kw/M 2, temperature of 60 ℃, humidity of 50%, light source-sample distance of 350mm, and irradiation time of 72 hours (120-minute cycle of 3-minute water spray + 117-minute irradiation × 36 times), and the elongation retention of the post-irradiation/pre-irradiation tensile test and the appearance after irradiation were evaluated in the tensile test based on jis k6723, in the evaluation of the elongation retention, 60% or more was regarded as good (o), less than 60% was regarded as bad (x), in the evaluation of the appearance, the case where the sample surface after irradiation was not cracked (cracked) was regarded as good (x), in the evaluation of the presence of cracks was regarded as bad (x), in the judgment of the weather resistance, the case where the elongation retention was o and the appearance was regarded as good (x), one of the elongation and the appearance was regarded as good (o) was regarded as good (x 3) results in the table.
The permeation resistance was evaluated by using a constant temperature and humidity cell at 70 ℃ C.. times.90% humidity. After leaving for 72 hours and taking out, the surface was judged as "good" when it was not sticky, and "bad" when it was sticky. The results are shown in tables 1 to 3.
TABLE 1
TABLE 2
TABLE 3
In conventional examples 1 and 2 using DOP or DINP, which were tested for reference, both weather resistance and permeation resistance were acceptable.
Example 1 and comparative example 1 were the case where 10 parts by mass of DOTP was added, and in example 1 where 0.1 part by mass of silicone rubber was added, both the weather resistance and the bleeding resistance were acceptable, while in comparative example 1 where no silicone rubber was added, cracks were generated after the weather resistance test, and the appearance was not satisfactory, and therefore the judgment of weather resistance was not satisfactory.
Examples 2 and 3 and comparative examples 2 and 3 were those in which the amount of DOTP added was 40 parts by mass and 100 parts by mass, and examples 2 and 3 in which 0.1 part by mass of silicone rubber was added were acceptable as in example 1, while comparative examples 2 and 3 in which no silicone rubber was added were also unacceptable in appearance as in comparative example 1, and were also unacceptable in the elongation retention rate, and therefore were judged to be unacceptable in terms of weather resistance.
as described above, 0.1 part by mass or more of silicone rubber is required to achieve both weather resistance and bleeding resistance.
It is understood from examples 6, 11 and 13 and comparative examples 7 to 9 that the amount of DOTP added is limited to 100 parts by mass because DOTP itself exudes when the amount of DOTP exceeds 100 parts by mass.
From examples 4 to 9, it is clear that the weather resistance and the bleeding resistance can be achieved at the same time even when 2.5 to 5 parts by mass of silicone rubber is added.
According to examples 4 to 6 and comparative examples 4 to 6, the silicone rubber can achieve both weather resistance and bleeding resistance, and the silicone oil, although having improved weather resistance, bleeds out on the surface of the composition to make the surface sticky.
Examples 4, 6, and 10 to 13 show that the same tendency is exhibited when the alkyl chain carbon number of the terephthalate is C8 to C10.
The present invention is not limited to the above embodiments and examples, and can be implemented by being variously modified.
