が用いられていた。Generally, when a vinyl chloride resin composition is immersed in mineral oil, the low-temperature brittleness of the composition is significantly reduced (deteriorated) regardless of the type of plasticizer contained in the composition. This is because when a vinyl chloride resin composition is immersed in mineral oil, the mineral oil enters into the vinyl chloride resin composition, extracts the plasticizer in the initial stage, transfers to the plasticizer, and further chlorinates the resin composition. By swelling the vinyl resin composition to reduce low temperature brittleness. In other words, as the temperature of a vinyl chloride resin composition decreases, its tensile strength and hardness gradually increase, but conversely its elongation decreases, and When external impact stress is applied below the temperature, there are cases where the material suddenly becomes brittle and easily broken (embrittlement phenomenon), and this embrittlement phenomenon is called low-temperature embrittlement. The temperature at which the tough state changes to the brittle state, that is, the temperature at which the material becomes brittle against sudden impacts, is called the transition temperature. If the low-temperature brittleness of a vinyl chloride resin composition is reduced (worsened) in this way, it will easily crack or crack even if a small force is applied to the vinyl chloride resin composition, which would normally not cause it to break in cold weather. Therefore, conventionally,
A high molecular weight polyester plasticizer is used as a method for improving the oil resistance of vinyl chloride resin compositions. This vinyl chloride resin composition is used as an M-edge sheath for electric wire cables. Electric wire cables using a vinyl chloride resin composition as an insulating sheath are also installed on mobile machines. The electric wires and cables installed in this mobile machine are often constantly immersed in mineral oil. For this reason, this type of electric wire cable uses a vinyl chloride resin composition in which a polyester plasticizer is used in the outermost layer to improve oil resistance.

ーブルを提供することを目的としている。However, polyester plasticizers added as a method to improve oil resistance can maintain most of the oil resistance in terms of tensile strength, elongation, etc., but have the problem of significantly reducing low-temperature brittleness after immersion in mineral oil. have. This is because the mineral oil enters the vinyl chloride resin composition, initially extracts the plasticizer, migrates to the plasticizer, and further swells the composition. Furthermore, even if plasticizers such as sebacate, azelate, and adipate, which have excellent cold resistance, are used in vinyl chloride resin compositions, there is a problem in that the low-temperature brittleness after immersion in mineral oil is significantly reduced. In addition, vinyl chloride resin compositions used as insulating sheaths for electric cables installed in mobile machines are
Even if a polyester plasticizer is used in the outermost layer, it is possible to maintain almost all oil resistance in terms of tensile strength, elongation, etc., but there is a problem in that low-temperature brittleness after immersion in mineral oil is significantly reduced. This is because the mineral oil enters the vinyl chloride resin composition, initially extracts the plasticizer, migrates to the plasticizer, and further swells the composition. Furthermore, even if plasticizers such as sebacate, azelate, and adipate, which have excellent cold resistance, are used in the outermost layer of the vinyl chloride resin composition, there is a problem in that the low-temperature brittleness after immersion in mineral oil is significantly reduced. There is. A first aspect of the present invention aims to provide an oil-resistant vinyl chloride resin composition that can suppress deterioration of low-temperature brittleness even when immersed in mineral oil. The second invention of the present application provides an oil-resistant electric wire cable that can improve the oil resistance and low-temperature resistance of the insulating sheath of the electric wire cable installed in a mobile machine and constantly immersed in machine oil (mineral oil).

(Leaving space below) The mineral oil immersion test in the comparative results of Examples, Comparative Examples, and Conventional Examples in Table 1 was conducted by immersing the vinyl chloride resin compositions in mineral oil (specifically Specifically,

) is expressed as a remaining rate (%). All of the examples in Table 1 contain 1 to 100 parts by weight of butadiene acrylonitrile rubber (NBR). This NBR is acrylonitrile butadiene rubber, nitrile rubber, or a copolymer of acrylonitrile and butadiene. This butadiene acrylonitrile rubber (NBR)
has good affinity with vinyl chloride resin and can suppress swelling caused by mineral oil, and as a result, can suppress a decrease in low-temperature brittleness. Moreover, the combined use with a polyester plasticizer can produce even greater effects. As is clear from the results in Table 1, Conventional Example 1 is a case where a phthalate plasticizer is blended into a vinyl chloride resin composition.
The tensile strength (Ts) of this vinyl chloride resin composition before being immersed in mineral oil is 20% to 150%, and as the amount of phthalate plasticizer increases, the tensile strength (Ts
) increases, and the elongation (E) significantly decreases by 5% to 15% compared to the elongation (E) before immersion in mineral oil. That is, it is hardened as a whole. Moreover, the embrittlement temperature of the vinyl chloride resin composition before immersing it in mineral oil is between -20°C and -40°C, and when it is immersed in mineral oil at 85°C,
50) The embrittlement temperature after h-immersion is 12°C to -6°C, which shows that the low-temperature brittleness has deteriorated significantly. Conventional Example 2 is a case where a polyester plasticizer is blended into a vinyl chloride resin composition, and the tensile strength (TS) of this vinyl chloride resin composition before being immersed in mineral oil is 70% to
As the blending amount of polyester plasticizer increases to 95%, the tensile strength (T s ) can be maintained at the same initial value, and the elongation (E) also changes to the elongation (E) before immersion in mineral oil. On the other hand, as the blending amount of the polyester plasticizer increases from 50% to 93%, the elongation (E) can be maintained at the same initial value. That is, the curing of the vinyl chloride resin composition can be maintained at the same initial value. However, the embrittlement temperature is 114°C to -30°C before the vinyl chloride resin composition is immersed in mineral oil, whereas it is 12°C after it is immersed in mineral oil at 85°C for 350 h. The temperature was -6°C, and the low-temperature brittleness was significantly worsened. Conventional Example 3 is a case where a sebacate-based or azelate-based plasticizer is blended into a vinyl chloride resin composition, and the tensile strength (Ts) of the vinyl chloride resin composition before being immersed in mineral oil is 15% to 150%. % and the amount of sebacate or azelate plasticizer increases, the tensile strength (T
s) increases, and the elongation (E) significantly decreases by 5% to 12% compared to the elongation (E) before immersion in mineral oil. That is, it is hardened as a whole. Moreover, the embrittlement temperature is 130°C to -60°C before the vinyl chloride resin composition is immersed in mineral oil, and the embrittlement temperature is 11°C to -60°C after it is immersed in 85°C mineral oil for 350 HI. At 6°C, low-temperature brittleness has significantly worsened. In addition, in Comparative Example 1, a phthalate plasticizer was used, and NBR
When 1 to 100 parts by weight of phthalate plasticizer is blended, the amount of phthalate plasticizer increases by 20% to 150% with respect to the tensile strength (Ts) before immersing this vinyl chloride resin composition in mineral oil. Accordingly, the tensile strength (Ts) increases, and the elongation (E) significantly decreases by 6% to 18% compared to the elongation (E) before immersion in mineral oil. That is, it is hardened as a whole. Moreover, the embrittlement temperature of the vinyl chloride resin composition before immersing it in mineral oil is from 124°C to
The embrittlement temperature after being immersed in 85°C mineral oil at -58°C was 12°C to -12°C, which shows that the low-temperature embrittlement has deteriorated significantly. Comparative Example 2 is a case where a sebacate-based or azelate-based plasticizer is used in a vinyl chloride resin composition and 1 to 100 parts by weight of NBR is blended, and the tensile strength of this vinyl chloride resin composition before being immersed in mineral oil is 15% to 15 for (Ts)
As the amount of sebacate or azelate plasticizer increases, the tensile strength (Ts) increases, and the elongation (E) is 8% compared to the elongation (E) before immersion in mineral oil. % to 18%, resulting in a severe decline. That is, it is hardened as a whole. In addition, the embrittlement temperature is 13% before the vinyl chloride resin composition is immersed in mineral oil.
The embrittlement temperature after being immersed in 85°C mineral oil for 350 hours at 2°C to -72°C is 14°C to -10°C, which shows that the low-temperature embrittlement has deteriorated significantly. Examples are cases in which a polyester plasticizer is used in a vinyl chloride resin composition and 1 to 100 parts by weight of NBR is blended, and the tensile strength (Ts) of this vinyl chloride resin composition before being immersed in mineral oil is The tensile strength (T
s ) can be maintained at the same initial value, and the elongation (E
) is also 55% of the elongation (E) before immersion in mineral oil.
As the blending amount of the polyester plasticizer increases to 95%, the elongation (E) can be maintained at the same initial value. That is, the curing of the vinyl chloride resin composition can be maintained at the same initial value. Furthermore, the embrittlement temperature of the vinyl chloride resin composition before being immersed in mineral oil is 6°C to -5°C.
The value of 0"C was set to -12°C to -50°C after immersion in mineral oil at 83°C for 350 hours, and the value (initial value) before immersing the vinyl chloride resin composition in mineral oil. In this way, when a polyester plasticizer is used in a vinyl chloride resin composition and 1 to 1-00 parts by weight of NBR is blended, the tensile strength and elongation are not significantly affected.
Deterioration of low temperature brittleness can be prevented. (Third and fourth inventions) Comparative examples of specific embodiments of the third and fourth inventions of the present application,

(Leaving space below) The comparison results of the examples, comparative examples, and conventional examples of oil-resistant vinyl chloride resin compositions used for insulating sheath materials of oil-resistant electric wire and cables in Table 2 are examples of oil-resistant vinyl chloride resin compositions. The results are similar to those of the comparative example and the conventional example.

On the other hand, in the example, the embrittlement temperature was 350HI before immersing the oil-resistant vinyl chloride resin composition used for the insulating sheath material of the oil-resistant electric wire cable in mineral oil, and 350HI in mineral oil at 85°C.
- Can be kept almost the same as after soaking. [Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below. Because it is a vinyl chloride resin composition made by adding a polyester plasticizer, stabilizer, and filler to polyvinyl chloride resin, an appropriate amount of butadiene acribonitrile rubber is blended.
Even if it is immersed in mineral oil, it is possible to suppress the deterioration of low-temperature brittleness. Additionally, 100 parts by weight of polyvinyl chloride resin may be blended with 30 to 150 parts by weight of a polyester plasticizer, 1 to 10 parts by weight of a stabilizer, 0 to 200 parts by weight of a filler, and 1 to 100 parts by weight of butadiene acrylonitrile rubber. Therefore, even when immersed in mineral oil, it is possible to suppress the deterioration of low-temperature brittleness. Furthermore, butadiene acrylonitrile rubber can be blended into the insulation sheath material of electric wire cables that use a vinyl chloride resin composition made by adding a polyester plasticizer, stabilizer, and filler to polyvinyl chloride resin as an insulation sheath material.
