Description
Technical field
The invention belongs to wire enamel and preparation field thereof, particularly a kind of self-lubricant lacquer coated line paint and preparation method thereof.
Background technology
Along with scientific and technical development, the improving constantly of living standards of the people, convenience, the stability requirement of people to electric product improves day by day.Therefore, the miniaturization of electrical equipment and electrical, lightness are important development trends, that is to say that the kinetic energy of output of onesize motor is larger, require in other words onesize motor to have larger power.Just having there is a problem in this, because the operating voltage of motor is generally constant, make output rating increase the working current that just must increase motor, and this will make the energy consumption P=I of motor
2r increases rapidly, causes the temperature rise of motor to increase, and working temperature raises.This has just accelerated the weathering process of insulation system indirectly.If the working temperature of motor exceedes the highest permission working temperature of insulation system, insulation system is will be rapidly aging and damage, and motor was lost efficacy.So in order to reduce the volume of motor, in improving the current capacity of conductor, must adopt the insulating material of high-quality more to improve the temperature classification of electrical machine insulation system.Therefore, development heat-resistant enamelled wire is the inevitable requirement of electrical equipment and electrical miniaturization, lightness trend.
Enameled wire is in insulated wire numerous kinds.Insulated wire is the electric wire for generation of electromagnetic induction.When the practical application of electromagnetic phenomenon, the conductor with insulation layer need to be coiled into winding, winding produces magnetic field by electric current or makes winding cutting magnetic line generation current, to realize the mutual conversion of electric energy and magnetic energy.For example electric motor changes electric energy into kinetic energy by electromagnetic induction exactly.And the purposes of insulated wire is carried out coiling winding exactly, be exactly the insulated wire of paint film as insulation layer that insulate so insulated wire is called again winding wire (winding wires) enameled wire.The insulation layer (being enameled wire coat) being coated with on enameled wire, should have good heat, electricity, machinery and chemical resistance.
Wire enamel is of a great variety, mainly contains acetals wire enamel, polyester wire enamel, polyurethanes wire enamel, polyamide-based wire enamel, polyamideimides wire enamel, polyester-imide class wire enamel, polyimide wire enamel etc.
In US Patent No. 3929714 by German Karl Schmidt and Beck application, introduce the polyester-imide paint that contains pyromellitic dianhydride component in formula.Thermal shock resistance, the heat-resisting solvent nature etc. of the enameled wire that this paint vehicle coats are all greatly improved.In addition in the example of this patent, introduce in the time manufacturing polyester-imide paint by single stage method, add cerium naphthenate and the cadmium acetate of minute quantity, can make high solids content, low viscous polyester-imide paint.
In the US Patent No. 4115342 of Rea insulated wire company of U.S. application, release a kind of low temperature scolding tin insulating lacquer layer.This enameled wire can be at 285 ~ 315 DEG C scolding tin within 1 second, at least 230 DEG C of thermoplastic flow dynamic temperatures.
Japan is more extensive to the research of polyester-imide paint modification, and the patent of announcement is maximum, and its method of modifying roughly can be summarized as following a few class:
The one, in polyester-imide paint, add polymeric amide or epoxy, its effect is water-fast, the wet-heat resisting that improves polyesterimide wire enamel, resistance to refrigerant, resistance to be full of cracks and resistance to electrified corrosive nature.
The clear 57-17904 of Japanese Patent Publication that changes into company application by Hitachi introduced the said firm's research to overcome insulating lacquer layer water-fast, the method of resistance to galvanic etching poor performance is: by terephthalic acid, m-phthalic acid or its lower alkyl esters, in 100 parts of weight of polyester imine resin that polyprotonic acid and di-imidogen carboxylic acid reaction make, add the macromolecular thermoplastic polyamide resin of 3 ~ 25 parts of weight, after mixing in organic solvent, the paint vehicle that obtains be directly coated with conductor on or be applied on other isolators, the enameled wire making resistance to cracking (5% extends) in water is good, water tolerance is (to time to rupture, hour) can reach 240 ~ 800, the imines of resistance to conventional polyester enameled wire only has 80 left and right.
Second method is in polyester-imide paint, to add melamine resin or phenol formaldehyde resin, or the two adds simultaneously, object is to improve the tack of insulating lacquer layer, improves the depainting performance jerking when disconnected, improve resistance to twisting performance, the insulating lacquer layer of especially large specification paste paint film.
The third method to polyester-imide modification of Japanology is blocked isocyanate etc. in polyester-imide paint.Its Main Function is to make insulating lacquer layer have straight weldering, resistance to high frequency performance, and improves heat punching and the stretching pin hole performance of enameled wire.
Polyimide (PI) enameled wire is the organic polymer enameled wire that current thermotolerance is the highest, can meet the requirement of life-time service at 220 DEG C.A large amount of stable five-membered ring on its molecular chain, has protected hydrocarbon key, makes it have good chemical-resistant resistance, resistance to solvent and radiation resistance, and especially aromatic polyimide contains the PI of phthalimide structure.
Yu Xinhai, [the development of polyimide high temperature-resistant wire enamel and enameled wire thereof such as Fan Liangzi, insulating material, 2011, 44 (5): 17-20] preparation method of a kind of polyimide high temperature-resistant wire enamel and enameled wire thereof is disclosed, be primarily characterized in that: in DMAc by 4, 4'-diamino-4 " hydroxyl tritane and 2, 2-pair-[4-(4-amino-benzene oxygen) phenyl] propane and 3, 3', 4, the polycondensation of 4'-benzophenone tetracarboxylic dianhydride obtains polyamic acid solution A, then by A and by 4, the polyamic acid solution B blend of 4'-diaminodiphenyl oxide and pyromellitic acid anhydride polycondensation obtains polyimide varnish, the enameled wire second-order transition temperature making is 293 DEG C, be expected to develop the enameled wire that temperature classification exceedes 240 grades.Meanwhile, the paint film making has low surface energy, low water absorption.
