Abstract
The present invention relates to a vacuum continuous impregnation insulating varnish, its main composition includes epoxy resin, unsaturated polyester resin, elaeostearic acid, BPO, DMP, DCP and hydroquinol. It is extensively applicable to various vacuum continuous insualting varnish impregnation treatment of various transformers and small-size transformer coils for car, motorcycle, electric tool motor, micromotor, small type motor and domestic equipments, and can greatly raise quality of products.
Description
The present invention relates to a kind of insulating impregnating varnish, relate in particular to a kind of electric winding insulation solvent-free immersion paint.
For a long time, in electrician trade, little for workpiece, in batches big, require general electric winding insulation dip treating, for example motor for washer stator, power tool rotor etc. often adopt common the immersing continuously or a soaking technology normal pressure under.And to some are little in batches, workpiece is big, demanding electric winding insulation dip treating, for example nuclear power then adopts the higher technique of vacuum pressure for dipping electrical of tooling cost with yoke coil, high-voltage motor winding etc.
Development along with modern science and technology progress and electronics and information industry, the product innovation of the electric winding that those workpiece are little, batch is big, have relatively high expectations continues to bring out, a lot of old products are also because of the market requirement upgrades, requires to improve, there is a sharp increase in output, for example micro-wave oven transformer, computer transformer, electric motor of automobile, motorcycle motor or the like.Original impregnation technology can not satisfy the requirement of product innovation and the demand in market.Therefore, produced a kind of new insulation-impregnating process----vacuum continuous impregnation technology.Original insullac that uses can not be applicable to new impregnation technology.This be because: 1. the common insullac that immerses, in vacuum environment, be easy to produce " foamization " and " atomizing " phenomenon, make solvent or a large amount of volatilization of reactive thinner in the lacquer liquid, cause these insullac can not solidify at last or can not reach final state of cure; 2. drip and soak insullac,, should not carry out mass-impregnation workpiece because of its lacquer fluid viscosity is bigger; 3. the vacuum pressure varnished insulation lacquer is long because of its lacquer liquid infiltration time again, also should not flood fast workpiece.So those original insullac that use all can not satisfy the requirement of vacuum continuous impregnation technology.
At present, the external vacuum continuous impregnation of insulating paint of producing as Toshiba Corp, because their lacquer fluid viscosity is very low, the vacuum volatilization of lacquer liquid divides very big, so, also only limit to the application of computer transformer and micro-wave oven transformer coil, but just can not be suitable for the insulation impregnating of those small and special electric machines, electric motor of automobile, motorcycle motor.
Purpose of the present invention provides a kind of special isolation impregnating varnish of vacuum continuous impregnation technology.This insulating impregnating varnish, have that the lacquer fluid viscosity is suitable, vacuum volatilization divides less, lacquer liquid wettability is good, gelation rate is fast, set time is short and working life advantage such as length, micro-wave oven transformer and computer transformer winding insulation impregnating can be applicable to, electric motor of automobile and motorcycle motor winding and other small and special electric machine, miniature transformer coil insulation dipping can be applicable to again.
The vacuum continuous impregnation of insulating paint of the present invention's design, be to be body material, carry out epoxide modifiedly, mix with reactive monomer and dilute with Resins, epoxy and unsaturated polyester resin, adding coupling solidifying agent and resistance join agent, and make by certain proportioning and production technique grouping mixing.
The vacuum continuous impregnation of insulating paint of the present invention's design, its major ingredient is:
1. Resins, epoxy;
2. unsaturated polyester resin;
3. eleostearic acid;
4. vinylbenzene;
5.BPO；
6.DMP；
7.DCP；
8. Resorcinol.
According to above-mentioned major ingredient, for different products, different workpiece and different insulation systems and different technical indicators, prepare, but just producing in serial form goes out the vacuum continuous impregnation of insulating paint of different size and kind according to different ratios.Can make the single-component product, also can make two component products, for user's different choice.
Through lacquer sample to exemplary embodiments, every test and the detection carried out, the testing data result who is obtained shows: the insulating impregnating varnish of the present invention's design, the overall target of aspects such as electric property after its vacuum characteristic, viscosity-temperature characteristics, wettability, perviousness, storage period, working life and the curing and physical strength, all obviously being better than other lacquer plants, satisfy processing requirement, can be used as the special isolation lacquer of vacuum continuous impregnation technology.Owing to possess characteristics such as vacuum volatilization is few, solidification value is low, set time is short, so it is again a kind of energy saving and environment friendly insulating impregnating varnish.
The insulating impregnating varnish of the present invention's design, be widely used in automobile, motorcycle, power tool motor, small and special electric machine, with other micro-machine, electric apparatus coil, and the vacuum continuous dipping insulation of home electric, electric transformer and miniature transformer coil is handled, the quality of product is improved greatly, tangible economic benefit is arranged.
