That is, in the present invention, to achieve this purpose, expensive and tensile strength,
There is a drawback that the mechanical performance such as tear strength and impact strength is relatively low, but the heat resistance is high and the hygroscopicity is low, and the electrical characteristics, that is, the insulation performance, electric dielectric properties, dielectric loss tangent, etc. are the best. PTFE and ETFE were selected as the optimal components to play this role.

素材であるとして選定して使用したのである。[0010] In the present invention, aromatic polycarbonate is a tape material that meets this purpose, but has the disadvantage that it has poor solvent resistance and slightly low heat resistance. Focusing on being a high-level general-purpose engineering polymer that has excellent mechanical (mechanical) properties and electrical performance that is inferior to PTFE and ETFE, assuming that it is the target product Then, it was selected and used as the most suitable material for the second layer configuration that matched the purpose.

In addition, ETFE is an extremely excellent insulating material most suitable for sharing the electrical insulation performance of the electrical insulating tape, and aromatic polycarbonate shares the mechanical (mechanical) physical properties of the insulating tape and improves the electrical insulating performance. It can be seen that this is an extremely excellent optimum reinforcing layer material which does not hinder the electrical insulation performance of the fluorine resin to be shared.

適の補強用構成成分である。Although not shown in the above physical properties table, the aromatic polycarbonate is similarly strong and has a moderate electric insulation performance. Compared with polyethylene terephthalate (PET) which is often used as an electric insulation tape material, Low water absorption unlike PET (water absorption of PET; 0.5 ~
0.8), there is very little decrease in electrical insulation performance due to moisture absorption,
In particular, since Tg (glass transition point) is about 80 ° C. as in PET, tan δ (dielectric tangent) increases sharply at this temperature, and the dielectric properties and insulating properties do not deteriorate. Group polycarbonate has a Tg of 148 ° C, a continuous heat resistance operating temperature of 115 ° C (measured according to JIS-K6735), and a deflection temperature under load (18.5K according to JIS-K6735).
gf / cm 2 measured under load) 135 ° C. and excellent mechanical properties under load, so that even within the operating condition range in which the electric equipment is used, which is the object of the present invention, it is relatively higher than 100 ° C. It is the most suitable reinforcing component for producing an electrically insulating laminated tape capable of maintaining excellent electrical insulation performance and mechanical performance stably over a wide range of temperature changes and a wide range of humidity changes over a high temperature range.

剤による接合プロセスは採用できない。(C) Next, the method of laminating and joining the two constituent material tapes for producing the electrically insulating laminated tape of the present invention is described. As described above, aromatic polycarbonate is an extremely excellent reinforcing material. In addition, since there is no solvent resistance and there is no resistance to the solvent of many adhesives, it is not possible to use a solvent-type adhesive or to use a solvent-type adhesive for the adhesive selection and bonding process.

Although it is excellent in terms of assuring the electrical characteristics of the product that can be produced with high productivity, it is not suitable for small lot production because it does not work well, so it is bonded by emulsion adhesive application-drying-dry lamination, The application of a so-called dry lamination process is optimal and recommended.

る。Since the adhesive used for laminating and joining the two material tapes is also a component of the electrical insulating tape, it is necessary to select the adhesive in consideration of the electrical insulation characteristics of the material constituting the adhesive. . Any adhesive can be selected as long as the adhesive constituent material satisfies such requirements and the adhesive performance between both constituent material tapes is sufficient. Also, it should be noted that PTFE and ETFE have poor adhesion and cannot be bonded with sufficient adhesive strength without pretreatment to improve the adhesion. That is.

In particular, when PTFE is used, PTFE has particularly excellent electrical insulation performance, but is difficult to adhere to, and requires careful corona discharge surface treatment.

Like the insulating tape consisting of PTFE and ETFE alone in the technology, even if it has a sufficient thickness to obtain the electrical insulating ability, the tensile strength, tear strength, impact strength, etc. required when using the electrical insulating tape In order to satisfy the requirements, the expensive PTFE and ETFE, meaning that the thickness must be increased to an unnecessary thickness in terms of electrical characteristics, mechanical (mechanical) performance must be guaranteed, and an electrical insulating tape must be manufactured. It can eliminate defects that have been used in large quantities and unnecessarily raised the price of products and reduced cost competitiveness.

The measurement results are as shown in Table 2. Naturally, the electrical insulation performance was extremely excellent, but the mechanical (mechanical) performance was far from that of the aromatic polycarbonate reinforced electrical insulation laminated tape of the present invention, and was practically used. Insufficient, and prices more than tripled, indicating poor cost competitiveness. [Table 2] [Comparison of performance of prepared samples] ｛Note｝ Each physical property was measured according to the following method. Tensile strength, breaking elongation: ASTM, D882 Peeling strength: A test sample cut to a width of 15 mm was subjected to a strograph (manufactured by Toyo Seiki) at a speed of 50 m / min at a speed of 18 m / min.
A 0 degree peel test was performed to measure the peel strength between the films. Volume resistivity: ASTM, D257

できる電気絶縁積層テープを安価に要求できる。As described above, the electrical insulating laminated tape according to the present invention has a required amount (thickness) of a PTFE or ETFE film for sharing the electrical insulating performance, and a mechanical (mechanical) film of the electrical insulating tape. Because it is a laminated and bonded integrated composite of aromatic polycarbonate film that has excellent mechanical (mechanical) performance and imparts high-level electrical insulation performance, which provides performance and imparts required mechanical (mechanical) physical properties Expensive PTF
E, ETFE film can be used to make electrical insulation tape without using mechanical (mechanical) physical properties at all and using only the minimum amount required to provide the required electrical insulation performance. For ETFE film alone electrical insulation tape,
Problems that could not be obtained without using extremely large (thick) PTFE and ETFE films, which far exceeded the amount required for imparting electrical insulation, for imparting mechanical (mechanical) properties. Excellent electrical insulation performance over a wide range of temperature changes and a wide range of humidity changes over a relatively high temperature range of over 100 ° C even within the operating condition range in which electrical equipment is used, which can eliminate defects. Inexpensively, an electrically insulating laminated tape capable of maintaining mechanical performance can be demanded.
