Abstract
The present invention relates to bimaleimide modified heat resistant unsaturated polyester resin which comprises the components of the following weight percentage: 40 to 65% of unsaturated polyester resin, 1 to 5% of bismaleimide, 10 to 25% of epoxy resin, 10 to 25% of tung oil estolide and 12 to 35% of styrene. The resin has the advantages of strong adhesive force, good heat resistance and insulating performance, strong mechanical strength, favorable moistureproof and mildewproof performance, good compatibility with electromagnetic wires and superior performance of refrigerant resistance.
Description
Technical field
The present invention relates to a kind of solvent-free insulated paint, particularly relate to a kind of solventless impregnating insullac.
Background technology
In the prior art, impregnated insulating paint is the important insulating material during motor, electric equipment products are made.Solvent-free paint and non-solvent paint are drawn together in varnished insulation, and non-solvent paint dipping cures that the time is long, and the needs that have are dipping lacquer repeatedly, and solidifies slowly, and solvent is volatile.
Along with the progress of expanding economy and science and technology, motor, electrical apparatus industry will be to reduced volume, weight reduction, increase capacity, improve the direction of exerting oneself, strengthening reliability and increase the service life develops.This just requires impregnated insulating paint and must improve temperature classification as early as possible and develop to the direction of solvent-free impregnating resin.And at present, because of the domestic solventless impregnating insullac that lacks, impregnated insulating paint is how with solvent type E, B level lacquer, and insulating property are poor, and physical strength is low, and the moisture resistance fungicidal properties is not high, and the consistency of insulated wire relatively poor, temperature classification is not enough.
Summary of the invention
The object of the invention provides a kind of solventless impregnating insullac, insulativity height, physical strength height, and resistance toheat is good.
Technical scheme of the present invention is: a kind of solventless impregnating insullac, it comprises m-phthalic acid unsaturated polyester resin, bismaleimides, Resins, epoxy, tung oil acid anhydride, vinylbenzene, and wherein the weight percent content of each component is: m-phthalic acid unsaturated polyester resin 40-65%, bismaleimides 1-5%, Resins, epoxy 10-25%, tung oil acid anhydride 10-25%, vinylbenzene 12-35%.
It also comprises initiator, stopper, initiation promotor, and the weight percent of described initiator is 0.1-2.0%, and the weight percent of described stopper is that the weight percent of 0.1-1.0%, described initiation promotor is 0.05-0.50%.
Described initiator is the oxidation diisopropylbenzene(DIPB).
Described stopper is a Resorcinol.
Described initiation promotor is cobalt naphthenate.
The present invention compared with prior art has the following advantages: this resin-bonded power is strong, resistance toheat and good insulation preformance, physical strength height, moisture resistance fungicidal properties are good, and its and insulated wire have the consistency of getting well, and have good cold-resistant matchmaker's performance.
Embodiment
Among the present invention, a kind of solventless impregnating insullac, it comprises m-phthalic acid unsaturated polyester resin, bismaleimides, Resins, epoxy, tung oil acid anhydride, vinylbenzene, and wherein the weight percent content of each component is: m-phthalic acid unsaturated polyester resin 50%, bismaleimides 3%, Resins, epoxy 12%, tung oil acid anhydride 12%, vinylbenzene 21%.
It also comprises initiator, stopper, initiation promotor, and the weight percent of described initiator is 1.0%, and the weight percent of described stopper is 0.5%, the weight percent of described initiation promotor is 0.5%.
Initiator is a dicumyl peroxide, and its molecular formula is C

2Co, molecular structural formula is as follows:
Cobalt naphthenate is for absorbing the compound of oxygen, and oxygen has inhibition to the initiated polymerization of unsaturated polyester, adds cobalt naphthenate and absorbs oxygen, has overcome the inhibition of oxygen, has promoted the carrying out of initiated polymerization.
The present invention is a solventless impregnating insullac, has quick solidifying, and viscosity varies with temperature soon, flowability and the good advantage of impregnability, insulation integrity is than the non-solvent paint excellence, and fugitive constituent is few during curing, can improve the whole heat conduction and the anti-moisture performance of electrical equipment and electrical, reduce materials consumption, shorten the production cycle.Its cure shrinkage is low, and mechanical property, moisture resistance anti-excellent property such as mould have good consistency, have good cold-resistant matchmaker's performance with insulated wire.Because of the m-phthalic acid unsaturated polyester resin is a heat resistant unsaturated polyester resin, through UL authentication (ULFile:E228349), spiral winding method evaluation heat-resistance index of the present invention is 212 ℃, twisted wire is 192.5 ℃ to method, be H level solvent-free impregnating resin, the vacuum and the normal pressure varnished insulation that can be widely used in B, F, H level military project, lifting, metallurgy, frequency conversion and cold-resistant matchmaker's motor, electrical equipment are handled.
