Description

本発明は、圧縮機と圧縮機駆動用モータとが一体となった圧縮機において、耐冷媒及び冷凍機油性に優れ、かつ巻線性に優れた駆動モータ用自己融着性絶縁電線をコイルに用いた圧縮機駆動モータ(以下、「ハーメチックモータ」と記載する。)に関する。   The present invention relates to a compressor in which a compressor and a compressor drive motor are integrated, and a self-fusing insulated wire for a drive motor that has excellent refrigerant resistance and refrigerating machine oil resistance and excellent winding properties is used as a coil. The present invention relates to a compressor drive motor (hereinafter referred to as “hermetic motor”).

空調機器や冷蔵庫などの冷凍機器に使用されるハーメチックモータは、冷媒及び冷凍機油環境下で運転されるものであり、特にモータ出力が大きい場合は、コイル振動を抑制するために巻線後ワニス処理を行うのが一般的である。しかしながら、ワニスには揮発性溶剤を使用しており、ワニス処理工程の環境悪化やワニス工程に負荷がかかり生産性の悪化を招くなどの課題がある。   Hermetic motors used in refrigeration equipment such as air-conditioning equipment and refrigerators are operated under refrigerant and refrigeration oil environments. Especially when the motor output is large, post-winding varnish treatment to suppress coil vibration It is common to do. However, since a volatile solvent is used for the varnish, there are problems such as deterioration of the environment of the varnish treatment process and load on the varnish process, leading to deterioration of productivity.

前記課題を解決する一つの方法として、ポリウレタン、ポリエステル、ポリエステルイミド、ポリアミドイミド、ポリイミドなど少なくとも1種以上の樹脂を塗布、焼付けしてなる絶縁皮膜の最外層に融着性を有した樹脂を塗布、焼付けしてなる融着皮膜を設けた自己融着性絶縁電線が用いられている。   As one method for solving the above-mentioned problem, a resin having fusion properties is applied to the outermost layer of the insulating film formed by applying and baking at least one kind of resin such as polyurethane, polyester, polyesterimide, polyamideimide, and polyimide. A self-bonding insulated wire provided with a fusion-bonded film formed by baking is used.

融着皮膜には、ポリビニルブチラール樹脂、ポリアミド樹脂、ポリビニルホルマール樹脂、ポリヒドロキシエーテル樹脂などの塗料を塗布、焼付けし、熱可塑性型融着皮膜を形成させる手法と、熱可塑性樹脂にフェノール樹脂、アミノ樹脂、イソシアネートなどの架橋剤を添加した塗料を半硬化の状態でエナメル焼付けし、熱硬化型融着皮膜を形成させる手法がある。   A coating method such as polyvinyl butyral resin, polyamide resin, polyvinyl formal resin, or polyhydroxy ether resin is applied to the fusion coating and baked to form a thermoplastic type fusion coating. There is a method of forming a thermosetting fused film by baking enamel in a semi-cured state to which a crosslinking agent such as resin or isocyanate is added.

前者の自己融着性絶縁電線は、融着皮膜が熱可塑性であるため、樹脂の融点を超える温度で再度融解させて融着させる必要がある。逆に、モータ運転中の温度では融解してはならない。従って、高温雰囲気下で使用されるハーメチックモータは、高融点の樹脂を使用せざるを得ない。   In the former self-bonding insulated wire, the fused film is thermoplastic, so it is necessary to melt and fuse again at a temperature exceeding the melting point of the resin. Conversely, it must not melt at temperatures during motor operation. Therefore, a hermetic motor used in a high-temperature atmosphere must use a high melting point resin.

これらの状況から、熱可塑性型融着皮膜を有する自己融着性絶縁電線の融着温度は、一般に200℃以上が必要となる。200℃以上の加熱を行った場合、モータの鉄心絶縁樹脂やリード線被覆樹脂などのポリエステル系材料(ポリブチレンテレフタレート、ポリエチレンテレフタレート、ポリエチレンナフタレートなど)を劣化または融解させ、モータの絶縁性能を低下させる問題がある。   Under these circumstances, the fusion temperature of the self-fusing insulated wire having a thermoplastic type fusion coating is generally required to be 200 ° C. or higher. When heating at 200 ° C or higher, polyester materials (polybutylene terephthalate, polyethylene terephthalate, polyethylene naphthalate, etc.) such as motor core insulation resin and lead wire coating resin are deteriorated or melted, and the insulation performance of the motor is reduced. There is a problem to make.

このため、ハーメチックモータには、後者の熱硬化型融着皮膜を有する自己融着性絶縁電線が選択される。従来、熱硬化型融着皮膜を有する自己融着性絶縁電線は、皮膜の可撓性に優れた分子量20,000以上の熱可塑性樹脂(樹脂基材)にアミノ樹脂の架橋剤を添加した塗料を半硬化状態でエナメル焼付けし、熱硬化型融着皮膜を形成可能な材料が使用されていた。   For this reason, the latter self-fusing insulated wire having the thermosetting type fusion coating is selected as the hermetic motor. 2. Description of the Related Art Conventionally, self-bonding insulated wires having a thermosetting fused film are paints obtained by adding a crosslinking agent of an amino resin to a thermoplastic resin (resin substrate) having a molecular weight of 20,000 or more, which is excellent in film flexibility. A material capable of forming a thermosetting fused film by enamel baking in a semi-cured state has been used.

また、架橋剤を過剰量加えることにより樹脂基材と架橋剤の重合だけでなく、架橋剤間の重合反応も進め、より密な分子構造を実現していた。これにより融着皮膜の耐熱性が向上し、ハーメチックモータ用途として使用可能な特性を得ることができる。
本発明に関する従来技術としては、例えば特許文献1,2が挙げられる。

Moreover, by adding an excessive amount of the crosslinking agent, not only the polymerization of the resin base material and the crosslinking agent but also the polymerization reaction between the crosslinking agents has been advanced to realize a denser molecular structure. As a result, the heat resistance of the fusion coating is improved, and characteristics that can be used for hermetic motor applications can be obtained.
Examples of conventional techniques related to the present invention include Patent Documents 1 and 2.

しかしながら、前述した従来の自己融着性絶縁電線を使用した場合、余分に含有されている架橋剤および架橋剤の未反応基が、ハーメチックモータに使用される冷凍機油のリン系極圧添加剤と反応し、スラッジを形成したり、極圧添加剤を減少させてしまう欠点があった。   However, when the above-described conventional self-bonding insulated wire is used, the extra crosslinking agent and the unreacted group of the crosslinking agent are added to the phosphorus-based extreme pressure additive of the refrigerating machine oil used in the hermetic motor. There were drawbacks in that they reacted to form sludge and reduce extreme pressure additives.

一方、モータの効率を向上するには、モータ鉄心のスロット内により多くの絶縁電線を巻線する(高占積率化する)必要がある。しかしながら、前述した従来の自己融着性絶縁電線の融着皮膜は、半硬化の状態で焼付けられており、融着皮膜の硬度が低く、融着皮膜表面の滑り性が悪いことから、巻線時に融着皮膜が削れ易い欠点や高占積率仕様のモータでは巻線できない欠点があった。   On the other hand, in order to improve the efficiency of the motor, it is necessary to wind more insulated wires in the slots of the motor core (to increase the space factor). However, the above-described conventional self-bonding insulated electric wire fused film is baked in a semi-cured state, the hardness of the fused film is low, and the slipperiness of the surface of the fused film is poor. At times, there are drawbacks that the fusion coating is easy to scrape, and that a motor with a high space factor specification cannot be wound.

本発明は前記事情に鑑みてなされ、冷媒及び冷凍機油環境下でも信頼性が高く、高占積率仕様のモータでも優れた巻線性を有する自己融着性絶縁電線を使用することにより、極圧添加剤が減少したりスラッジが形成されることなく信頼性の高いハーメチックモータの提供を目的とする。   The present invention has been made in view of the above circumstances and is highly reliable even under refrigerant and refrigeration oil environments, and by using a self-bonding insulated wire having excellent winding properties even in a motor with a high space factor specification, It is an object of the present invention to provide a highly reliable hermetic motor without reducing additives or forming sludge.

前記目的を達成するため、本発明の第1の発明(以下、「第1発明」と記載する。)は、少なくとも分子量20,000以上のポリヒドロキシエーテル樹脂及びポリサルホン系樹脂からなる樹脂基材、並びに1分子中に2個の官能基を有する架橋剤からなり、ポリヒドロキシエーテル樹脂とポリサルホン系樹脂との質量比が、不揮発分で20/80〜90/10の範囲であり、ポリヒドロキシエーテル樹脂とポリサルホン系樹脂の不揮発分換算合計量100質量部に対する、1分子中に2個の官能基を有する架橋剤量が不揮発分換算で10〜40質量部である樹脂を有効成分として含有する熱硬化型絶縁材が、導体上に絶縁皮膜を介して塗布焼付けされてなる融着皮膜を有し、耐冷媒及び冷凍機油性を有する自己融着性絶縁電線をコイルに用いたことを特徴とする圧縮機駆動モータを提供する。 In order to achieve the above object, a first invention of the present invention (hereinafter referred to as “first invention”) includes a resin base material comprising at least a polyhydroxy ether resin having a molecular weight of 20,000 or more and a polysulfone resin, and Ri Do crosslinking agent having two functional groups per molecule, the weight ratio of the polyhydroxy ether resin and polysulfone-based resin is in the range of non-volatiles 20 / 80-90 / 10, polyhydroxyether Heat containing, as an active ingredient , a resin in which the amount of a cross-linking agent having two functional groups in one molecule is 10 to 40 parts by mass in terms of nonvolatile content with respect to 100 parts by mass of the resin and polysulfone-based resin in terms of nonvolatile content A curable insulation material has a fusion coating that is applied and baked on a conductor via an insulation coating, and uses a self-fusing insulated wire with resistance to refrigerant and refrigerating machine oil as a coil.

前記目的を達成するため、本発明の第2の発明(以下、「第2発明」と記載する。)は、前述した第1発明のハーメチックモータにおいて、融着皮膜の少なくとも最外層に、巻線の滑り性を向上させる滑剤を配合したハーメチックモータを提供する。   In order to achieve the above object, a second invention of the present invention (hereinafter referred to as “second invention”) is the above-described hermetic motor of the first invention, wherein at least the outermost layer of the fusion coating has a winding. Provided is a hermetic motor containing a lubricant that improves the slipperiness.

It is also possible to use a resin produced by a polymerization reaction of bisphenol A, bisphenol S and epichlorohydrin.

ポリヒドロキシエーテル樹脂とポリサルホン系樹脂との質量比は、不揮発分換算で20/80〜90/10の範囲であることが好ましく、30/70〜80/20の範囲であることが特に好ましい。該質量比が20/80未満であると、融着皮膜は十分な融着性が得られなくなり、90/10を超えると、高温雰囲気下及び冷媒・冷凍機油中での融着性が低下する。   The mass ratio between the polyhydroxy ether resin and the polysulfone-based resin is preferably in the range of 20/80 to 90/10 in terms of nonvolatile content, and particularly preferably in the range of 30/70 to 80/20. When the mass ratio is less than 20/80, the fusion film cannot obtain sufficient fusing property, and when it exceeds 90/10, fusing property in a high temperature atmosphere and in refrigerant / refrigerant oil decreases. .

また1分子中に2個の官能基を有する架橋剤としては、2価の安定化イソシアネート、尿素樹脂、ベンゾグアナミン樹脂、2価の有機酸、2価の有機酸の誘導体が挙げられる。具体的には、2価の安定化イソシアネートとして、テトラメチレンジイソシアネート、ヘキサメチレンジイソシアネート、パラフェニレンジイソシアネート、2,4−トリレンジイソシアネート、2,6−トリレンジイソシアネート、キシリレンジイソシアネート、ジフェニルメタン−4,4”−ジイソシアネート、ジフェニルエーテル−4,4’−ジイソシアネート等をフェノール性水酸基、アルコール性水酸基等を有する化合物でマスクしたものである。   Examples of the crosslinking agent having two functional groups in one molecule include divalent stabilized isocyanate, urea resin, benzoguanamine resin, divalent organic acid, and divalent organic acid derivatives.

より具体的には、市販のミリオネートMS−50、コロネート2501、2507、2513、2515(いずれも日本ポリウレタン工業社製)、デュラネート17B60−PX、TPA−B80X、MF−B60X、MF−K60X、E402−B−80T(いずれも旭化成社製)等を例示することができる。   More specifically, commercially available Millionate MS-50, Coronate 2501, 2507, 2513, 2515 (all manufactured by Nippon Polyurethane Industry Co., Ltd.), Duranate 17B60-PX, TPA-B80X, MF-B60X, MF-K60X, E402- Examples thereof include B-80T (all manufactured by Asahi Kasei Co., Ltd.).

また、尿素樹脂としては、市販のUFR65、UFR300(いずれも日本サイテック社製)、ベンゾグアナミン樹脂としては、市販のサイメル1123、マイコート102、105、106、1128(いずれも日本サイテック社製)を例示することができる。   Examples of the urea resin include commercially available UFR65 and UFR300 (both manufactured by Nippon Cytec Co., Ltd.), and examples of the benzoguanamine resin include commercially available Cymel 1123, Mycoat 102, 105, 106, 1128 (all manufactured by Nihon Cytec Co., Ltd.). can do.

ポリヒドロキシエーテル樹脂とポリサルホン系樹脂の不揮発分換算合計量100質量部に対する、1分子中に2個の官能基を有する架橋剤量は、10〜40質量部の範囲であることが好ましく、15〜30質量部の範囲が特に好ましい。架橋剤量が10質量部未満の場合、高温雰囲気下および冷媒・冷凍機油中における融着力が低下しやすくなり、冷媒抽出率も増大する。架橋剤量が40質量部を超える場合、融着が困難になる。   The amount of the crosslinking agent having two functional groups in one molecule is preferably in the range of 10 to 40 parts by mass with respect to 100 parts by mass of the total amount of the non-volatile content of the polyhydroxy ether resin and the polysulfone resin. A range of 30 parts by weight is particularly preferred. When the amount of the cross-linking agent is less than 10 parts by mass, the fusion force in a high-temperature atmosphere and in the refrigerant / refrigerant oil tends to decrease, and the refrigerant extraction rate also increases. When the amount of the crosslinking agent exceeds 40 parts by mass, fusion is difficult.

以上説明した通り、例示した化学物質をそれぞれ任意に選択し、所要量を配合し、シクロヘキサノン等の有機溶媒に溶解することにより、本発明に使用した自己融着性絶縁電線の融着皮膜の材料となる樹脂塗料が得られる。次いで、前記の樹脂塗料を定法により導体に他の絶縁皮膜を介して半硬化状態にエナメル焼付けし、本発明に使用した自己融着性絶縁電線が得られる。   As described above, each of the exemplified chemical substances is arbitrarily selected, blended in a required amount, and dissolved in an organic solvent such as cyclohexanone, thereby making the material for the fused film of the self-bonding insulated wire used in the present invention. A resin paint is obtained. Subsequently, the resin paint is enamel-baked on the conductor in a semi-cured state through another insulating film by a usual method, and the self-bonding insulated wire used in the present invention is obtained.

図1は、本発明で使用した自己融着性絶縁電線の構成を例示する断面図である。この自己融着性絶縁電線は、導電率が良好な電気銅からなる導体1と、該導体1上に設けられた絶縁皮膜2と、該絶縁皮膜2上に設けられた融着皮膜3からなっている。   FIG. 1 is a cross-sectional view illustrating the configuration of a self-bonding insulated wire used in the present invention. This self-bonding insulated wire includes a conductor 1 made of electrolytic copper having good conductivity, an insulating film 2 provided on the conductor 1, and a fusion film 3 provided on the insulating film 2. ing.

次いで、この自己融着性絶縁電線を巻線してコイルを作製後、加熱処理を施すことで余分な残基の少ない3次元構造が形成されたコイルとなり、ハーメチックモータに要求される耐冷媒及び冷凍機油性が得られる。   Next, after winding this self-bonding insulated wire to produce a coil, a heat treatment is performed to form a coil in which a three-dimensional structure with few extra residues is formed. Refrigerator oiliness is obtained.

第2発明は、第1発明で使用した自己融着性絶縁電線の融着樹脂塗料に滑剤を配合し、導体に他の絶縁皮膜を介して塗布して焼付けた自己融着性絶縁電線を使用した他は、前記第1発明と同一である。   The second invention uses a self-bonding insulated wire obtained by blending a lubricant with the fusion resin coating of the self-bonding insulated wire used in the first invention, and applying and baking the conductor through another insulating film. The rest is the same as the first invention.

但し、前記ポリヒドロキシエーテル樹脂とポリサルホン系樹脂との質量比は、不揮発分換算で20/80〜90/10の範囲であることが好ましく、30/70〜80/20の範囲であることが特に好ましいことは第1発明で使用した自己融着性絶縁電線の融着樹脂と同一であるが、該質量比が90/10を超えると、自己融着層の皮膜強度が低下するため、十分なすべり性が得られない。   However, the mass ratio between the polyhydroxy ether resin and the polysulfone-based resin is preferably in the range of 20/80 to 90/10 in terms of nonvolatile content, and particularly preferably in the range of 30/70 to 80/20. What is preferable is the same as the fusion resin of the self-bonding insulated wire used in the first invention. However, if the mass ratio exceeds 90/10, the film strength of the self-bonding layer is lowered, so that it is sufficient. Slip properties cannot be obtained.

ポリヒドロキシエーテル樹脂とポリサルホン系樹脂と1分子中に2個の官能基を有する架橋剤の不揮発分換算合計量100質量部に対する、滑剤量は、1〜5質量部の範囲であることが好ましい。滑剤量が1質量部未満であると、高占積率仕様モータ巻線が可能なすべり性が得られず、5質量部を超えると融着率が低下してくる。   The amount of lubricant is preferably in the range of 1 to 5 parts by mass with respect to 100 parts by mass in terms of non-volatile content of the polyhydroxy ether resin, the polysulfone-based resin and the crosslinking agent having two functional groups in one molecule. If the amount of lubricant is less than 1 part by mass, the slipperiness that enables high space factor specification motor winding is not obtained, and if it exceeds 5 parts by mass, the fusion rate decreases.

この滑剤としては、ポリエチレン系ワックス、マイクロクリスタリンワックス、ポリテトラフルオロエチレン等のフッ素系ワックス、ステアリン酸アミド等のアミド系ワックス、ミツロウ、カルナバワックス、モンタンワックス等およびこれらワックスの分子末端を変性させたものを単独もしくは複数選択して配合することができる。   As this lubricant, polyethylene wax, microcrystalline wax, fluorine wax such as polytetrafluoroethylene, amide wax such as stearamide, beeswax, carnauba wax, montan wax, etc. and the molecular ends of these waxes were modified. A thing can be mix | blended by single or multiple selection.

以下の実施例中の例1〜例24において、ポリヒドロキシエーテル樹脂はPKHH(商品名;UCC社製)、ポリサルホン系樹脂はYPS−007(商品名;東都化成社製)、2価のイソシアネートはミリオネートMS−50(商品名;日本ポリウレタン工業社製)、アミノ樹脂はサイメル370(商品名;日本サイテック社製)、滑剤はポリテトラフルオロエチレン(ダイキン工業社製)である。
