Description

  The present invention relates to a cable with ink and a molded product with ink.

  Among polyolefin resins, which are thermoplastic resins, polyethylene and polypropylene resins are general-purpose resins that are excellent in chemical resistance, insulation, and processability, and are inexpensive. Therefore, they are widely used in cable insulators and various molded products. Yes.

  On the other hand, in order to distinguish between products on cable insulators and various molded products, printing is generally performed with ink or the like.

  However, since polyethylene and polypropylene resins are nonpolar resins, the wettability to ink is low, and there was room for improvement in terms of ink adhesion.

  Therefore, in order to improve the adhesion of ink, in Patent Document 1 below, the surface of the covered electric wire conveyed at a constant speed is subjected to plasma treatment to improve the wettability of the surface, and the ink is applied to the plasma treatment portion. A method of printing has been proposed.

  However, the covered wire with ink obtained by the method described in Patent Document 1 has the following problems.

  That is, in the coated electric wire with ink described in Patent Document 1, as the conveyance speed of the coated electric wire increases, a shift occurs between the place where the plasma treatment is performed and the place where the ink is printed. As a result, when a part of the ink adheres to the plasma non-processed part that is not plasma-treated, a part of the ink is easily peeled off from the plasma non-processed part.

  For this reason, the cable with an ink and the molded product with an ink which can fully suppress peeling of an ink were calculated | required.

  This invention is made | formed in view of the said situation, and it aims at providing the cable with an ink which can fully suppress peeling of an ink, and a molded article with an ink.

  The present inventors have repeatedly studied in order to solve the above problems. As a result, the present inventors have found that the ink and the insulator to which the ink is attached both solve the above problems by including a polar resin containing a polar group. It came to complete.

  That is, the present invention provides a transmission medium for transmitting a signal, a cable including at least one insulator provided so as to surround the transmission medium, and at least one insulator among the at least one insulator.

The ink includes a first polar resin, and the ink includes a second polar resin having a second polar group.

  According to the cable with ink or the molded article with ink of the present invention, it is possible to sufficiently suppress the peeling of the ink from the cable or the molded article.

  In addition, the present inventors infer the reason why the above effect is obtained in the cable with ink or the molded product with ink of the present invention as follows.

  That is, in the cable with ink or the molded article with ink, the ink-attached insulator or molded article and the ink in the cable insulator each include a polar resin containing a polar group. The present inventors speculate that the bonding force due to the intermolecular force increases at the interface between the product and the ink.

  In this case, the first polar group in the first polar resin and the second polar group in the second polar resin do not sufficiently contain the carbonyl group. Can be suppressed.

  In the cable with ink or the molded product with ink, the first polar group in the first polar resin is composed of a carbonyl group, and the second polar group in the second polar resin is composed of a carboxyl group. It is preferable.

  In this case, peeling of the ink from the cable or the molded product can be more effectively suppressed.

  In the cable with ink or the molded product with ink, the content of the second polar group in the ink is preferably larger than the content of the first polar group in the ink-attached insulator or the molded product. .

  In this case, the ink is more easily peeled off from the cable or the molded product than in the case where the content of the second polar group in the ink is equal to or less than the content of the first polar group in the ink adhesion insulator or the molded product. It can be suppressed sufficiently.

  In the cable with ink or the molded product with ink, the first polar resin preferably contains a maleic anhydride-modified resin.

  In this case, as compared with the case where the first polar resin does not contain a maleic anhydride-modified resin, it is possible to more sufficiently suppress the peeling of the ink from the cable or the molded product.

  In the cable with ink or the molded product with ink, the second polar resin is preferably composed of at least one selected from the group consisting of an acrylic resin, a vinyl acetate resin, and a phthalic acid resin.

  In this case, it is possible to more sufficiently suppress the peeling of the ink from the cable or the molded product as compared with the case where the second polar resin is not composed of at least one selected from the group consisting of acrylic resin, vinyl acetate resin and phthalic acid resin. .

  In the present invention, “the first polar group in the first polar resin is composed of a carbonyl group” means at least 1 when the first polar resin is composed of a plurality of types of first polar resins. It means that the first polar group in the first polar resin of the seed is composed of a carbonyl group, and not only that the first polar group in all the first polar resins of plural types is composed of the carbonyl group, It shall also be said that the first polar groups in the plurality of types of the first polar resins are composed of carbonyl groups, and the remaining first polar groups in the first polar resin are not composed of carbonyl groups.

  In the present invention, “the second polar group in the second polar resin is composed of a carboxyl group” means that when the second polar resin is composed of a plurality of types of second polar resins, at least 1 It means that the second polar group in the second polar resin of the seed is composed of a carboxyl group, not only that the second polar group in all of the plurality of types of second polar resins is composed of the carboxyl group, It shall also be said that the second polar groups in the plurality of types of second polar resins are composed of carboxyl groups, and the remaining second polar groups in the second polar resin are not composed of carboxyl groups.

  Next, the cable 10 and the ink 20 will be described in detail.

<Cable>
The cable 10 includes a conductor 1, an insulator 2, and an insulator 3.

(conductor)
The conductor 1 may be configured by only one strand, or may be configured by bundling a plurality of strands. Moreover, the conductor 1 is not specifically limited about a conductor diameter, the material of a conductor, etc., It can determine suitably according to a use.

(Insulator)
The insulator 3 is a so-called sheath, and protects the insulator 2 from physical or chemical damage. The insulator 3 is an ink adhesion insulator, and the base resin of the insulator 3 has a first polar resin.

The first polar resin includes a first polar group. The first polar group is not particularly limited as long as it is a polar group. Examples of the first polar group include a carbonyl group (—CO—), a hydroxyl group (—OH), and an amino group (—NH ₂ ). An acyl group (RCO-) such as a maleic anhydride group, a carboxyl group (—COOH), an ester group (—COOR), an amide group (—NHCO—), an acetyl group (—OCOCH ₃ ) represented by the following structural formula , Carboxylic anhydride group (—CO—O—OC—) and the like.

  The first polar resin is not particularly limited as long as it is a resin containing a first polar group, but as the first polar resin, for example, a main chain containing an olefin as a structural unit, and the first polar group is a side chain The resin provided as is mentioned. Examples of such olefins include ethylene, propylene, and butadiene. The first polar resin may include only one first polar group or a plurality of the first polar groups.

  Specific examples of the first polar resin include maleic anhydride-modified resin, ethylene-methyl acrylate copolymer (EMA), ethylene-ethyl acrylate copolymer (EEA), ethylene-butyl acrylate copolymer (EBA), Examples thereof include ethylene vinyl acetate copolymer (EVA), ethylene-acrylic acid copolymer (EAA), and ionomer.

Examples of maleic anhydride-modified resins include maleic anhydride-modified polyolefins such as maleic anhydride-modified polyethylene and maleic anhydride-modified polypropylene.

  The content (R1) of the first polar group in the first polar resin is not particularly limited, but is preferably 0.8% by mass or more. R1 is more preferably 2% by mass or more.

  However, from the viewpoint of maintaining the heat resistance and mechanical properties of the base resin, R1 is preferably 15% by mass or less.

  The base resin of the insulator 3 may further contain a nonpolar resin in addition to the first polar resin.

  Examples of the nonpolar resin include polyolefins such as polyethylene, polypropylene, polybutylene, and polybutene. Examples of the polyethylene include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and high density polyethylene (HDPE).

  Specific examples of the second polar resin include acrylic resin, vinyl acetate resin, phthalic acid resin, and amide resin. Among these, an acrylic resin, a vinyl acetate resin, a phthalic acid resin, or a mixture of two or more thereof is preferable because of good adhesion to the insulator 3 that is an ink-adhering insulator.

  In particular, when a maleic anhydride modified resin is used as the first polar resin, it is preferable to use an acrylic resin, a vinyl acetate resin, a phthalic acid resin, or a mixture of two or more thereof as the second polar resin. In this case, peeling of the ink 20 from the insulator 3 can be more sufficiently suppressed.

  The content (R2) of the second polar group in the ink 20 may be greater than R1 or less than or equal to R1, but is preferably greater than R1. In this case, the separation of the ink 20 from the cable 10 can be more sufficiently suppressed than when R2 is equal to or less than R1.

  When R2 is larger than R1, the difference between R2 and R1 (R2-R1) is not particularly limited as long as it is larger than 0% by mass, but R2-R1 is more preferably 20% by mass or more. .

  R2 is not particularly limited, but is preferably 20% by mass or more, and more preferably 25% by mass or more.

Thus, the insulated wire 4 is obtained.

  Next, an insulator-forming resin composition (second insulator-forming resin composition) for forming the insulator 3 is prepared. This second insulator-forming resin composition can be obtained by melt-kneading a base resin and, if necessary, an additive. Here, the base resin includes at least a first polar resin.

  Next, the insulated wire 4 obtained as described above is covered with the above-described second insulator-forming resin composition.

However, in this case, the insulator 2 becomes an ink adhesion insulator and needs to be made of the same material as that of the insulator 3 in order to sufficiently prevent the ink 20 from being peeled off from the insulator 2.

  In the first embodiment, the ink 20 is attached only to the insulator 3, but the ink 20 may be attached only to the insulator 2 without being attached to the insulator 3. However, in this case, the insulator 2 becomes an ink adhesion insulator and needs to be made of the same material as that of the insulator 3 in order to sufficiently prevent the ink 20 from being peeled off from the insulator 2. In this case, the insulator 3 does not necessarily include the first polar resin.

  Further, in the first embodiment, the insulator provided so as to surround the conductor 1 is composed of the two insulators of the insulator 2 and the insulator 3, but the insulator provided so as to surround the conductor 1. As long as it is at least one, it may be composed of only one insulator, or may be composed of three or more insulators. However, when the insulator provided so as to surround the conductor 1 is composed of only one insulator, the insulator is an ink adhesion insulator, and the ink adhesion insulator is composed of the same material as the insulator 3. It is necessary to Further, when the insulator provided so as to surround the conductor 1 is composed of three or more insulators, at least one of the three or more insulators becomes an ink adhesion insulator, and the ink adhesion insulator Needs to be made of the same material as that of the insulator 3. Here, all of the three or more insulators may be made of an ink-attached insulator, or only a part thereof may be made of an ink-attached insulator.

  Further, in the first embodiment, the cable 10 is configured by a metal cable, and the transmission medium for transmitting a signal is configured by the conductor 1, but the transmission medium may be configured by an optical fiber instead of the conductor 1. .

Here, the optical fiber 24 is provided so as to penetrate the insulator 25. Here, the insulator 25 is made of the same material as the insulator 3. On the other hand, the ink 320 is made of the same material as the ink 20. For this reason, also with the cable 300 with ink, peeling of the ink 320 from the cable 310 can fully be suppressed. In the cable 310 of the cable 300 with ink, the support wire 21 and the two tension members 22 and 23 are not necessarily required and can be omitted.
