Abstract

PURPOSE:To obtain titled wire of high heat and refrigerant resistance, also with improved adhesive potential, electrical and mechanical properties and productivity, for use in electrical apparatus, by coating and baking on a conductor, a coating comprising each specific linear polyesterimide resin and polysulfone resin in a specific ratio. CONSTITUTION:The objective wire can be obtained by coating, on a conductor, a coating comprising, for example, (A) a linear polyesterimide resin of formula (R and R' are each >=2C divalent organic group; n>=3) prepared by the reaction between (i) >=0.5mol of a polyhydric alcohol, (ii) trimellitic anhydride, and (iii) a primary diamine (e.g., 4,4'-diaminodiphenyl-methane) and (B) a polysulfone resin in a ratio of 7/3-3/7. The coating operation may be either direct or indirect through the use of another insulating material.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-single-layer insulated wire with excellent heat resistance and resistance to attempts.

Traditionally electrical equipment, ) 11! Labor saving and simplification of the coil W of the Shin-Kin equipment, the viewpoint of safety and health and environmental pollution control in the face impregnation process of the II equipment.
Since then, so-called self-curing adhesive conductors have been used, in which a heat-adhesive coating film is provided on a conductor via an IIA layer. Polyvinyl butyral lIIMi1, polyvinyl formal joka, kyōenso polyamide, phenoxy juro, etc. are often used as the man layer for this self-detachable sweat-extinguishing trout, but this one is 150℃
As a result, if an excessive current is applied to the coil or if it is exposed to air, the degree of oxidation will decrease, and the insulation will be poor. ~kJ woodcutter supply direct and low- - miniaturization of the most electric power plant - (I product method same cost could not be answered. To deal with this A, the above-mentioned 1! It is made by blending phenol l! pus, melamine resin, epoxy stabilizing isocyanate, and other reefing agents to create a thermal adhesive, and then baked in a hardened or semi-hardened state to create a self-adhesive, non-stick adhesive. It is also a common practice to obtain a varnish, but with such a product, it is necessary to bake the base with loquat edge breakage and separate streaks. −
That shortcoming was rare. Also, polysulfo 788m etc.

The skin is mixed with a small vinyl formal Ili skin.
The temporary adhesion is good, but 1M~W&9 is inferior in properties. It could not be used as a closed trout for the motor used in the i#am mine, and the practical use of the I# was no longer available.

In view of the above-mentioned shortcomings, the inventors of the present invention, Ij1 et al., have developed a self-adhesive electric melting method that uses a straight-sided polyester imide that has excellent heat injection and coolness properties and is capable of falling over. However, the adhesive strength of this electric wire RIA8TMD-2519
When measured according to the method of No. 75, it shows an optical value, but it has been found that when both ends of a helical coil are pulled in the axial direction, it tends to cause peeling. This is FilI! It is thought that this is due to the small deviation of lIk when ll is increased, and the contact layer is small.As a result of intensive research to improve this point, we found that by mixing phenoxy additives, heat resistance and refrigerant resistance can be improved. It was discovered that the touchability was improved without reducing the sexiness.

The present invention was made based on this knowledge, and it is possible to apply linear polynisdelimide (am) expressed by the general formulas 1 and 4 on the conductor directly or through another insulating layer. Heat-resistant, cold-resistant g
Note: Adhesive self-skinned loquats are provided with electric trout.

In addition, as 1O~1 (307 Lψ) of the polyhydric alcohol component, 0.1 to 0.2 mole of the aromatic dicalphonic acid such as terephthal It or its V1 base is added to the above-mentioned polyhydric alcohol 0.1 to 0.2 mole. The use of φ-valent alcohol mixed with 1 l of varnish and 5 L of varnish in 3 to 10 mol gives a stronger effect, so the use of 7 is preferable.

Mix it with an organic barrier agent such as cresol or naphtha so that the mixing ratio is simple from /3 to 3/7, and then heat it directly on top, preferably using Tsukuda's loquat W pigeon, and then bake it in a lid. It is obtained by Furthermore, ridged mackerel-like polynisderimide 11I4JI11
The reason for limiting the ratio of the maple base of the phenoxy and phenoxy sides as mentioned above is that if the polyester side is more than this axis number, the M contact property will be insufficient, and if it is less than this axis number, the refrigerant resistance will be poor. It's because it becomes more.

The underlying insulating layer is preferably made of heat-resistant materials such as polyester, polyesterimide, aromatic polyamideimide, i*polymer polyimide, polyesteramideimide, etc., but polyvinyl formal or koshoki@totera may also be used. Note that the ratio of the thickness of the base insulating layer to the thickness of the additional layer is appropriately l:a, a to 1.2.

The inventive product thus obtained - N-type loquat-density - has heat resistance, refrigerant resistance, haze-coating and oxidation reaction when used during toileting. However, it has the advantage that electric and smoker custom orders are the same as above.Also, since it can be manufactured with the same baking rod as the base loquat layer, it has good seating properties.
