[Prior art] Conventionally, insulated wires used in speaker sound coils, motor coils, etc. have been made to have self-adhesive properties. As shown in the first figure, a fused coating is formed on the surface of the insulating coating covering the wire. . The insulating coating 2 is formed of an insulating paint such as polyester, and the fused coating 3 is formed of an alcohol-soluble polyamide-based resin coating dissolved in an organic solvent. Nowadays, with the increase in the performance of electric machines in recent years, for example, the load on sound coils for motors and motor coils has become larger, and the insulated wires constituting the above-mentioned coils are required to have high financial performance. In the conventional insulated wire, the heat-resistant temperature of the insulating coating material such as polyester forming the insulating film 2 is about 350 ° C. When the temperature is higher than 350 ° C, the characteristics of the insulated wire are deteriorated. Therefore, there is a conventional method for forming an insulating film from a material having heat resistance. However, a new problem arises in that the insulating film and the fused film are easily peeled. [Summary of the Invention] The main object of the present invention is to solve the problems of the existing insulated wires and self-adhesive insulated V wires, which are poor in heat resistance, and the insulation is easily peeled by the acid-fused coating. In order to achieve the above-mentioned object, the present invention forms an insulating coating on the outer peripheral surface of the lead wire, and forms a primer on the outer peripheral surface of the 200404310, and the edge film, and forms a coating on the outer peripheral surface of the silk coating. In the present invention, a heat-resistant material is used to form an insulating film, and then a material with good male connection between the insulating film and the fused film is used, and a primer is formed between the insulating film and the fused film to increase the insulating film. Peel strength to the fused film. [Embodiment] Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. The second figure is a perspective view showing a state in which each film of the insulated wire according to one embodiment of the present invention is peeled off, and the third figure is a cross-sectional view of the insulated wire. In this example, the insulated wire 10 is made of copper or! The outer peripheral surface of the lead wire i i made of a conductive metal such as g is covered with a ceramic insulating film 12. The diameter of the lead 11 is, in this example, 0.02 to 0.6 mm. An outer peripheral surface of this insulating coating film 12 is covered with a primer coating 13, and an outer peripheral surface of the aforementioned primer coating 13 is covered with an adhesive coating film 14. The ceramic insulation coating 12 is a coating composition composed of a compound containing zirconium and a compound containing silicon in a proportion not shown in the fourth figure. The coating is applied to the outer peripheral surface of the lead wire 1 and then thermally cured to thereby harden it. The wrong, Shi Gui formed. The thickness of this ceramic insulating film 12 is 3 to 12 // m in this example. The fifth figure discloses the chemical structural formula of the ceramic insulating film 12. The ceramic insulating film 12 will be described below. The ceramic insulating film 12 is formed by using the following coatings (including (a) + (b) + (cM00 parts by weight)) composed of the following composition (a) (b) (c). 12 200404310 (a) is a general formula (R12si) n (〇R2) 2 (where ri is an organic group having 1 to 8 carbon atoms; R2 is an alkyl group having 1 to 5 carbon atoms or a carbon atom; At least one selected from the group of polyorganosiloxanes represented by the number of 丨 ~ 4), which is 5 to 55 parts by weight in terms of solid content; (b) is based on the general formula Zr (0R) 4 (in the formula, R is a hydrocarbon residue having 1 to 5 carbon atoms) a hydrolyzed product of the four pyrotechnic oxy hammer and tetranicotinyl hydrazone represented by jin and a partial shrinkage of the hydrolyzed product I At least one kind of selected b compound selected from the ethnic group of the compound, or the compound and the formula Si (0R) 4 (wherein, r is a hydrocarbon residue with a carbon number of 丨 ~ 5) The mixture of at least one kind of Wei compound selected from the group consisting of the hydrolysate of the tetrahydrocarbyl thiophene and tetrahydrocarbyl hydrazine and the partial polycondensate of the hydrolysate, and the lysine weight thereof is converted into W ~ 15 parts by weight; (c) is organic Agent, accounting for 30 ~ 94 · 5 parts by weight; for coating ▲, and the product 'contains very fast reaction to polyorganic stone sintering, and has heat resistance, recording resistance, and resistance to silk or The composition of the Wei-fusing compound is also made into a flexible, highly heat-resistant insulating film, so it can be suitably used in the ceramic insulating film 12 described above. "Axial parts (a), (b), and (e) caps can be added. Additives such as organic acids, inorganic acids, various surfactants, chelating agents, chelating agents, inorganic compounds, etc. = ⑷ 成 财 's polyorganic appearance is used as a pure, thermally flexible and flexible, edge-covering agent. ΚOrganic The hydrodecomposed product of sillicon sintered silicon or oxidized sintered silicon is used for dehydration 13 200404310. It is a substance formed by polycondensation using pure silicon paint. It is based on the combination of silicon oxide L0-Si-) and has An earthen spout with methyl and phenyl as side chains 疋 The early ride formed by mixing early methyl or early triclosan with dimethyl, diethyl, or disilane is dissolved in 溶It is to further advance the polycondensation side of the hydroxyl group in the residual polysiloxane burning, thereby forming A substance with a body mesh structure. The methyl group in the fired group has the highest heat resistance and excellent water repellency. Therefore, 'this' inspection shot has a green color, which is mainly Gu Erjiao resin. _ Serving amount of 45 to 6 ⑽ (mass percentage #%), preferably 50 to 55% (mass percentage). The ratio of the ⑷ component in the coating composition can be 5 to 55 weight in terms of solid content. 25 to 50 parts by weight. When it is less than 5 parts by weight, the coating film is too thin, and the osmium component increases, so the coating rate is deteriorated. When it exceeds 55 parts by weight, An excessive increase is not suitable because the operability is deteriorated and the coating film is too thick to cause cracking. In the wound, the tetrahydroxanthine will be hydrolyzed when there is a trace amount of water, and _ will become the hydrolyzed tetrahydrofuran, and this hydrolyzed product will re-ride and produce some polycondensates. Since it has a high molecular weight and produces a thin film over time, it acts as a highly heat-resistant coating agent together with the aforementioned rhenium component, and has the effect of promoting the hardening, high density, and high heat resistance of the rhenium component. The above (bM parts of ton oxygen silk) has a very fast hydrolysis and heavy polycondensation reaction. Therefore, it can be hardened by heating with low temperature by using (a) Miron materials. 14 200404310 R is, for example, an alkyl group having 5 carbon atoms, and may be methyl, ethyl, η-butyl, sec-butyl, η-propyl, or the like. Specific examples include tetramethanol, tetraethanol, Tetra-n-butanol, tetra-sec monobutanol, tetrapropanol, etc., and one or two or more of the foregoing can be used simultaneously. As the component (b) above, especially tetra-n-butanol is The above-mentioned oxygen-seeking secretion of the plutonium component, in addition to the alkoxy group, also includes its hydrolyzate and a partially heavy polycondensate of the hydrolyzate. The hydrolyzate and part of the heavy hydrolyzate can be prepared from the mixture. The shellfish produced in the tetrahydrocarbylamine may also be a substance that is pre-mixed when the mixture is adjusted. The tetrafluorene-based silicon fluorene of the tritium nuclear towel may also have the same purpose as the tetrahydrocarbyloxy group described above. The water is slowly decomposed by the presence of water, and it is called a tetrapeptide hydrolyzate, and this hydrolyzate is re-contracted. Part of the heavy polycondensate is produced to produce a film with a higher molecular weight, so it can be used as a highly heat-resistant coating agent to promote the hardening, high-density, and high heat-resistance of the rhenium component. Tetrahydrocarbyl oxide has a very slow hydrolytic and heavy polycondensation reaction. Therefore, 'by mixing the two, the hydrolytic rate will be moderated to improve operability' and by adjusting the hardness of the coating film (soft It is possible to implement measures such as anti-cracking. R in the tetraalkoxy group is, for example, an alkyl group having 5 carbon atoms, a methyl group, an ethyl group, a t-butyl group, an η-propyl group, or a p-propyl group. Examples include tetramethoxy thief, tetraethoxy weir, tetrabutoxy thief and tetrakispropoxysilane, etc., which may be one kind of these substances or use two or more of them at the same time. 15 200404310 As the above ( b) component, preferably tetraethoxysilane. In addition to the tetraalkoxysilane, the tetraalkoxysilane in the component (b) also contains hydrolysates and partial condensation polymers of these hydrolysates. The hydrolyzate and part of the polycondensate can be in the group In the product, a substance composed of tetraalkoxysilane may be used in advance in the adjustment of the composition by using a hydrolyzed product or a partially heavy polycondensate. As the component (b), a tetraalkoxy hammer is used. The mixing ratio in the case of a mixture with tetraalkoxysilane is preferably 20 to 70, 30 to 80 parts by weight, and more preferably 30 to 60: 4 to 70 parts by weight (wherein the total of the two is 1). (0 parts by weight). The proportion of the component (b) in the coating composition is 0.5 to 15 parts by weight, preferably 1 to 5 parts by weight in terms of solid content. When it is less than 0.5 parts by weight, The hardening reaction will be slowed down, which will make it heat resistant. If it exceeds 15 parts by weight, the reaction will be too fast, and the hardening reaction will proceed excessively, which will cause cracks and peeling on the coating film. And therefore not very good. The organic solvent in the component (c) is a mixed dispersant of the component (a) and (b) and a concentration adjusting agent ', and is also used as a curing rate adjusting agent for the component (a) (b). Examples of the organic solvent in the component (c) include low-boiling organic solvents, ethylene glycol derivatives, and alcohols. Specific examples include xylene, xylene, methyl ethyl ketone, ethylene glycol, vinyl acetate, ethylene glycol, monoethyl ether, diethylene glycol monobutyl ether, n-butyl alcohol, methanol, and ethanol Wait. Moreover, one kind or two or more kinds of the aforementioned substances may be used simultaneously. The organic solvent of the component (C) may include the organic 16 200404310 solvent contained in (a) and (b). The ratio of the hafnium component in the coating composition is 30 to 94.5 parts by weight, and preferably 80 to 80 parts by weight. When it is less than 30 parts by weight, the composition will become high and the workability will be deteriorated, and the coating film will be too thick, which may cause cracking. -On the other hand, if it exceeds 94.5 parts by weight, the coating film will be too thin, and insulation will not be achieved, so it is not good. Next, the primer 13 will be described. The undercoat 13 is made of organic resin-modified silicon. The organic resin-modified Shigui is a cold-mixing method in which Shigui paint and organic resin are mixed in a non-volatile content ratio of 50 to ⑽: 忉 to 50 (total 100), or an organic resin and a solvent are mixed. In the case of introducing nitrogen, weaving was performed to remove water and condensate, so that the same proportion of varnish as in the case of the cold mixing method was added, and the temperature was raised. After removing the condensed water, add a solvent to adjust its dryness. Degree, etc., so as to make it by cooking. In the case of the aforementioned hybrid, the cold-mixing method uses chlorooxy group as the functional group, while the cooking method uses fluorenyloxy group and hydroxide group. As for the organic nano's, one kind or two kinds of resins such as epoxy group, acrylic group, polyester group, alkyd group, urethane group and epoxy modified group are used. In the description, the ratio of the impurities to the organic resin in the 'undercoat 13' is 5Q to ⑽: 1 () to 50 (total 〇) and 60 to 80 · 20 to 40 (total ⑽) is more preferable. In the above, in order to improve the heat resistance and reactivity of the primer layer 13, in organic resin modified materials 17 200404310 hydrolysates of alkoxy metal and alkoxy metal are added, and partial condensation polymers of the hydrolysates Yes. These metal alkoxides may be, for example, tetraalkoxysilane, tetraalkoxy hafnium and tetraalkoxy zirconium. Examples of the organic resin-modified silicon material include the following. 1.

The thickness of the fusion surface 14 is 3 to 10 in this example. 18 200404310 The reason for forming the undercoat layer 13 between the ceramic insulating film 12 and the fused film 14 on the insulated wire 10 is as follows. That is, the silicon oxide oxide forming the ceramic insulating film 12 has poor adhesion due to the resin paint such as a polyamide resin or a polyimide resin which forms the coating film 14. Shu Jing was carefully covered. For example, when the insulated wire is used as a sound coil for a speaker, when the high-power axis of the speaker H is operated, due to the large amplitude action of the speaker lion, the ceramic insulation film and the fusion film will peel off. This may cause the wires to fall off from the mandrel on the speaker. Moreover, the fused film is an insulated wire formed directly on the surface of the ceramic insulating film, which is under high temperature conditions. _The influence of the force will melt the coating and Tao Wei Yuanguan will peel off, which may cause the sound of the insulated wire. The insulated wire 10 ′ is between the aforementioned mutual _ miscellaneous difference _ Yuan Yuan Na 12 and the fused blanket ㈣ by organic resin with good adhesion between the insulating coating 12 and the fused coating u of Tao Jing. The formation of the primer 13 ′ can prevent the fused film 14 from being peeled off from the ceramic insulating cover 12. —In addition, because this insulated wire 1G is formed of an organic resin modified material of a 咼 density film with a good heat resistance and a high degree of resistance due to its undercoat 13, it can ensure heat resistance and flexion during use. The thickness of the coating 13 is about 1 to 5 " m. 19 200404310 This primer is 13 and its ceramic insulation film 12 is made of a hydrolyzed product of a silicon varnish and a silicon varnish, in addition to oxidized stones (a coating composition containing a compound of zirconium and silicon). When the hydrolyzate and molecular mixture of tetraalkoxytitanium and tetraalkoxysilane are mixed with the above-mentioned materials with ceramic particles such as insulating particles or fibrous powder of about 3 to 50% of various mixtures , Also applicable. The insulated wire 1G formed by the primer 13 between the ceramic insulating film 12 and the fused film 14 of the insulated wire 10 can be experimentally described by the methods described above. (1) The sixth image of the MMP experiment of the speaker reveals that the insulated wire with a primer layer formed between the Tao Weiyuan film and the fused film and the insulated wire without a knuckle are used as the MMP of the speaker when the speaker coil is made. Experimental data. Among them, the undercoat of the insulated wire used in this experiment was polyacetate. This MMP test is as shown in the seventh figure, and the insulated wire with the undercoat diameter and the insulated wire without the undercoat diameter of 025 are wound on the mandrel 21 as the speaker-off sound coil 2 (). A resistance value of 3 · 5 _ was made to be heated at 2 (rc for 3 () minutes, so that the entire coil of the wire self-adheres to the mandrel 21. This experiment uses _ with a primer line and without The primer coated insulated wire 20 200404310 is coated with polyamine based paint. # ^ $ 亚 “轴 21 疋 is formed by coating a glass fiber cross tube with a polyamine resin material. The eighth picture shows the group with The seventh figure is a cross-sectional view of the sound of the loudspeaker and the side of the high-output speaker. A vibrating plate 34 is arranged at the edge. ^ Is a plate body, 36 is a cymbal body, 37 is a magnet, and the magnetic circuit of the speaker is formed by these items. The caliber of the two output speakers in this example is a gourd. The ninth picture is The eighth _ of the high-end losers shoes, the actual turn of the shoes. At this ninth time, 'pink noise generated by the pink noise oscillator NG (By the weighted network and standard), the high-output speaker% is driven by the noise canceling circuit CL and amplifier A. Then, the voltage is measured by an actual value type voltmeter 7. Calculate its power value. MMP experiments start with the input of watts and drive the high-output speaker% for one minute, and then _ wood ~ two knife clock repeats ten times in this mode, and the impedance added from the speaker's voice coil at various points in time Use the value to find the temperature, and repeat the experiment with the turn-on watts increasing every time until the sound coil 20 for the speaker is destroyed. The results of this MMP test are shown in Figure 26. In the case where the voice coil for a speaker has a primer coated insulated wire (indicated by 〇), it is more obvious than when the insulated coil without a primer is used (indicated by △). The disconnection temperature is relatively high. 21 200404310 And in this MMP experiment, at the end, the polyimide-based varnish film was thermally melted, causing the speaker voice coil 20 to fall off the mandrel 21, and this speaker is used for The sound coil 20 is disconnected due to contact with the plate body 34 or the carcass 35. However, when the speaker sound coil 20 is disconnected, the ceramic insulation film is not melted and the covered state of the wire is maintained to maintain its insulation performance. (2 ) Fiber ribbon separation test: A copper oxide coating, a primer, and a polyamine-based varnish were sequentially applied on a copper plate, and a heat stripping test was performed using the fiber ribbon. As a comparative example, a copper plate was sequentially coated with After oxidizing hammer silicon insulating coating and polyamine paint and heating and curing, peel test using fiber tape is performed. The heating temperature, time and film thickness of each film are as follows. Heating temperature / time · 250 ° C / 30 minutes (oxidation Staggered baby insulation coating) 200 ° C / 30 minutes (primer and polyamine paint) Film thickness: 5 / zm (common to all coatings) As a result of this peeling test, the film forming the primer does not peel from the fiber tape. On the other hand, a film without a primer is peeled off by attaching a film formed of a polyamine paint to the fiber ribbon. (3) Sound coil mandrel-coil peeling experiment. For the ceramic transformer insulation line 'Nuosi_Chengdu Dujiu', which uses oxidized zeolite as a ceramic insulating coating and polyamine paint as the fusion coating 22 ^ UU4U431〇 Coupled, the amount of film peel strength. Among them, polyester silicone paint is used as the primer. The test method is as follows. -First, wind the ceramic with a diameter of 0.15 on a cylindrical polyimide mandrel with a straight diameter of 20 mm. The ceramic insulation is deleted by the pie wire 5 and wide. C is heated for 3G minutes, and the whole winding wire is integrated on the mandrel. Thereafter, as shown in the tenth figure, after the mandrel 40 and the winding wire 41 are cut along the axis together into one #half, the winding wire 41 is reduced along the mandrel 4G _ the line direction _ and the winding direction thereof. -Side peeling. The measurement results of the peel strength at this time are shown in Fig. 11. From the tenth figure, it can be seen that the formation of a primer-coated lead wire has a peeling strength that is approximately 50% higher than that of an insulated wire without a primer. At the end of this peeling test, the coating was broken on the ceramic-coated insulated wire that formed the primer, and in the case where the ceramic-coated insulated wire that did not form the primer was on the interface between the Tao Wei margin film and the fused film spring. Peeling occurs. As in the above-mentioned example of the embodiment of the insulated wire according to the present invention, an insulated wire is formed on the outer peripheral surface of the wire and a primer is formed on the outer peripheral surface of the insulated film. The implementation type is its superordinate concept. Insulated wires in the implementation form of this higher-level concept, for example, the insulation film is formed of hafnium oxide, and the situation is formed by the amide fine grease or polyimide grease paint. 23 200404310 When the adhesion between the forming materials of the coating film is not good, by using a material with good adhesion to the two, a primer is formed between the insulating coating and the fusion coating, which can increase the insulation coating and the fusion coating. Peel strength between. As a result, the insulated wire and the self-adhesive insulated wire, for example, in the case where the insulated wire is used as a voice coil for a speaker, can prevent the insulating coating and the fused coating from being caused by a large amplitude operation during high-power operation of the speaker. Stripping, so as to avoid the situation where the wire is loosened from the speaker's mandrel.
