Description
The invention relates to the pliability epoxy resin powder coating composition.Composition of the present invention, particularly in the occasion of using as powder coating, because it has invested wet fastness, thermotolerance, resistance to chemical reagents, bond strength, the good coating of thermal cycling, thereby suitable electronic unit, for example the insulated enclosure powder coating of coil components such as ceramic condenser, impedance network, hybrid integrated circuit, inducer done.
Up to now, insulation as ceramic condenser or inducer-coil is coated with the epoxy powder coating of carrying out usefulness, open the blending epoxy and the bisphenol derivative that constitute by bisphenol-type epoxy resin and phenolic resin varnish type epoxy resin that proposes in the flat 1-210419 communique the spy, and the coating formed such as promotor.
Yet the performance of this composition can't be very satisfied, and particularly weather resistance and the thermotolerance aspect for mechanical shock and thermal shocking is still waiting to improve.
Wet fastness, excellent heat resistance have been the objective of the invention is to provide, especially for mechanical shock and the good epoxy resin composition of thermal shocking weather resistance in order to solve existing the problems referred to above in the prior art.
Include bisphenol-type epoxy resin 40～80%(weight according to epoxy resin powder coating composition provided by the invention by epoxy equivalent (weight) 180～2500) and phenolic resin varnish type epoxy resin 60～20%(weight of epoxy equivalent (weight) 180～230) blending epoxy 100 weight parts formed and contain the formula I
(n is 0～8 integer in the formula)
The solidifying agent of shown bisphenol derivative (the epoxy group(ing) 1 equivalent curing dose with respect to this blending epoxy is 0.6～1.5 equivalent), curing catalyst 0.2～5 weight part, fusing point is more than 200 ℃, median size is nylon fine powder 5～30 weight parts of 18～50 μ m, and silica fine powder 100～200 weight parts of median size 1～50 μ m.
Used blending epoxy is the mixture of bisphenol-type epoxy resin and phenolic resin varnish type epoxy resin among the present invention, is solid state at normal temperatures.The melting point of blending epoxy, usually in 50～90 ℃ of scopes for well, when using as powder coating under this scope, melt viscosity is suitable, appearance of film is good, the surface does not produce crowfoot cracks or the limit of collapsing (ダ レ), all level and smooth everywhere the filming in surface.
Bisphenol-type epoxy resin is a bisphenol diglycidyl, bis-phenol as this class uses known A type and F type bis-phenol, the bis-phenol that particularly uses the A type is for well, phenolic resin varnish type epoxy resin is a novolac glycidyl ethers, resol as this class uses known phenol phenol aldehyde type or cresols phenol aldehyde type etc., particularly uses the cresols novolac type phenolic resin for well.The epoxy equivalent (weight) of blending epoxy, the cooperation ratio by regulating both also is adjusted in 350～1000 scopes.Preferred blending epoxy is bisphenol A type epoxy resin 40～80%(weight of epoxy equivalent (weight) 180～2500 among the present invention) and cresols phenol aldehyde type epoxy resin 20～60%(weight of epoxy equivalent (weight) 180～250) the average epoxy equivalent (weight) of composition be 350～1000, fusing point is 50～90 ℃ Resins, epoxy.
Bisphenol derivative shown in the formula I before composition of the present invention contains.In the bisphenol derivative shown in this formula I, copolymerization is right to be generally 0～8, is preferably 0～6.Because cooperated the solidifying agent of this class, it is good to obtain pliability, cross-linking density is high simultaneously, the high cured article of second-order transition temperature more than 100 ℃.The usage quantity of this solidifying agent is 0.6～1.5 equivalent with respect to the every epoxy equivalent (weight) of blending epoxy, is preferably 0.7～1.2 equivalent.
