。Conventionally, this type of high dielectric constant rubber insulating composition has been made by adding additives such as barium titanate, carbon black, metal oxides, and metal powder to polar synthetic rubber having polar groups such as halogen and acrylonitrile. It was common.
しかし、この種のゴム絶縁組成物は温度によって誘電率

本発明の要旨は、電気絶縁性に優れた非極性合成コムに
高誘電率付与剤としてチタン酸カルシウムを添加した点
にある。The gist of the present invention is that calcium titanate is added as a high dielectric constant imparting agent to a non-polar synthetic comb having excellent electrical insulation properties.
電気絶縁性に優れた非極性合成ゴムとしては、エチレン

Rubber chemicals such as stabilizers, anti-aging agents, colorants, and flame retardants may be added as necessary.
また、２種以上のゴムをブレンドして用いても良い。Further, two or more types of rubber may be blended and used.
次に本発明の実施例について比較例と共に説明する。Next, examples of the present invention will be described together with comparative examples.
各側とも次表に示す配合を混練後成型したものである。Each side was molded after kneading the formulation shown in the following table.
各側の数値の単位は重量部である。The units of numbers on each side are parts by weight.
次に、上記表の組成について、

（２）また、誘電率の温度特性を第２図に、夫々示す。Next, regarding the composition in the table above, (1) Figure 1 shows the relationship between the dielectric constant and the content of calcium titanate (CaTiO+) and barium titanate (BaTi04), (2) Also, the temperature characteristics of the dielectric constant are shown in Figure 2.
第１図によれば、チタン酸カルシウムの含有量が増すに
従い誘電率が大きくなる傾向があり、含有量を加減する
ことによって任意の誘電率が得られることがわかる。According to FIG. 1, it can be seen that the dielectric constant tends to increase as the content of calcium titanate increases, and that any dielectric constant can be obtained by adjusting the content.
例えば誘電率１１を得るには３５０重量部（ＰＨＲ）添
加すればよい。For example, to obtain a dielectric constant of 11, 350 parts by weight (PHR) may be added.
これに対し、チタン酸バリウムをチタン酸カルシウムと
同量添加した場合は、約１／２の誘電率しか得られない
ことがわかる。On the other hand, it can be seen that when barium titanate is added in the same amount as calcium titanate, a dielectric constant of only about 1/2 is obtained.
第２図はチタン酸カルシウムおよびチタン酸バリウムを

温度変化の少ない特徴を示している。FIG. 2 shows the temperature characteristics of the dielectric constant when calcium titanate and barium titanate are added at 150 and 300 PHR, respectively, and shows a characteristic that there is little temperature change from room temperature to 90° C. or higher.
以上説明したような本発明であれば、非極性ゴムにチタ

バリウムの場合より高い誘電率をもつ組成物を得ること
ができたのである。According to the present invention as described above, by adding calcium titanate to non-polar rubber, it was possible to obtain a composition having a higher dielectric constant than the conventional barium titanate.
しかも前記実施例結果からも明らかなように、温度変化
も少なく、電気絶縁性も極めて良好である。Furthermore, as is clear from the results of the examples, there is little temperature change and the electrical insulation is extremely good.
このような好結果の得られる理由は、チタン酸カルシウ

、ゴムに混合した複合体においては、チタン酸塩単体と
は異なった挙動を示すためと考えられる。The reason for such good results is that, unlike barium titanate, calcium titanate is not a ferroelectric material, so when mixed with rubber, it behaves differently than titanate alone. Conceivable.
