Description
Technical field
Material of the present invention relates to a kind of heat resisting unsaturated polyester modified epoxy, the multi-functional heat resistant unsaturated polyester resin modified epoxy that a kind ofly specifically be adapted to sink, drip, roll, multiple motor dippings such as rotation, VPI requires.
Background technology
Unsaturated polyester resin is a kind of common resins, obtains in the electric insulation field to use widely, and especially common as solvent-free immersion paint, it is cheap, has medium electric and mechanical property, and big but its shortcoming is a shrinking percentage, cohesive force is relatively poor; The advantage of Resins, epoxy is that cohesive force is strong, electric and physical strength is high, it is lower that but its shortcoming is a shrinking percentage, and price is also higher, and the leeway that temperature classification is regulated is little, if unsaturated polyester and Resins, epoxy are mixed use, do not make them that chemically crosslinked takes place mutually, then be difficult to reach the complementation on the performance, industrial method commonly used is that unsaturated polyester and vinylbenzene are crosslinked, and Resins, epoxy and amine or anhydrides curing both sides only are miscible, rather than crosslinked.
Summary of the invention
The present invention proposes a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy, it is big to have overcome in the prior art unsaturated polyester shrinking percentage, and second-order transition temperature is low, simultaneously hard the and crisp problem of Resins, epoxy, it is big to have brought into play unsaturated polyester thermotolerance adjustment leeway, flexibility is good, and Resins, epoxy is good advantage electrically, has realized the grid IPN, performance complement, cooperate various enameled wires, thereby make temperature classification reach the B level, be adapted to sink, drip, roll, the various needs of VPI to the C level.
In order to solve the problems of the prior art, technical scheme provided by the invention is:
A kind of multi-functional heat resistant unsaturated polyester resin modified epoxy is characterized in that: comprise phthalic anhydride, cis-butenedioic anhydride, propylene glycol, the mol ratio of described phthalic anhydride, cis-butenedioic anhydride, propylene glycol is 1:1:2.2, handles through epoxidation after synthesizing again, and has more versatility.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy is characterized in that: described multi-functional heat resistant unsaturated polyester resin modified epoxy acid number scope is at 20 mgKOH/g-50mgKOH/g.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy is characterized in that: the synthetic back of described multi-functional heat resistant unsaturated polyester resin modified epoxy adds HG type solidifying agent end-blocking.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy, it is characterized in that: acid number adds HG-1 type solidifying agent end-blocking at the multi-functional heat resistant unsaturated polyester resin modified epoxy of 20 mgKOH/g, the package stability of resin is prolonged, be suitable for VPI and use.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy, it is characterized in that: acid number adds HG-2 type solidifying agent end-blocking at the multi-functional heat resistant unsaturated polyester resin modified epoxy of 50 mgKOH/g, have quick-setting performance, help occasion such as soaking and using dripping.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy is characterized in that: also add oxirane value at 0.5 dihydroxyphenyl propane or bisphenol f type epoxy resin, can use in VPI, its viscosity is low, seepage force is strong, and package stability is strong, can keep life-time service.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy, it is characterized in that: acid number adds HG-1 type solidifying agent and oxirane value at 0.4 novolac epoxy end-blocking at the multi-functional heat resistant unsaturated polyester resin modified epoxy of 50mgKOH/g, its cohesive force is strong, the second-order transition temperature height.
Aforesaid a kind of multi-functional heat resistant unsaturated polyester resin modified epoxy is characterized in that: described acid number is 1:1:0.05-0.10 at the multi-functional heat resistant unsaturated polyester resin modified epoxy of 20 mgKOH/g, oxirane value at the weight percent of 0.5 dihydroxyphenyl propane or bisphenol f type epoxy resin, HG-1 type solidifying agent.
The invention has the beneficial effects as follows:
1, the present invention at first is synthetic a kind of heat resistant unsaturated polyester resin, second step was to realize the grid IPN with the Resins, epoxy that is fit to, the 3rd step was a controlledization processing, the synchronization that realizes unsaturated polyester and Resins, epoxy is solidified, the thermopositive reaction of unsaturated polyester is steady for epoxidation heat absorption institute effectively, reduces shrinking percentage and internal stress.Package stability solves by effective latent; Curing speed is implemented by the decomposition of complex compound.
When 2, solid in synthetic unsaturated polyester, acid number≤20mgKOH/g, it and the crosslinked deficiency of HG-1 type solidifying agent, so its mechanical property is partial to polyester and epoxy mixed type; When acid number 〉=50mgKOH/g, behind it and HG solidifying agent crosslinked, still remaining too much carboxyl, its result has quickened the reaction with epoxy group(ing), has shortened the change time with fixed attention; Only between 20mgKOH/g-50mgKOH/g, with dihydroxyphenyl propane and bisphenol f type epoxy resin best reaction effect is arranged, and during with the phenolic aldehyde epoxy reaction, has only acid number when 50mgKOH/g55 mgKOH/g, just filled up between bisphenol-A epoxy and the phenolic aldehyde epoxy, because of lacking the deficiency that hydroxyl causes, reach effective solidified purpose.
3, when the use oxirane value was 0.5 Resins, epoxy, its viscosity was lower, and optimum joins in the unsaturated polyester of acid number 20-50mgKOH/g, add oxirane value at 0.2 Resins, epoxy, suitable use, should not use, but increased the toughness of coating as solvent impregnated resin as topcoating.
4, unsaturated polyester acid number of the present invention is at 20 mgKOH/g-50mgKOH/g, and oxirane value all can add HG-1 type solidifying agent at the Resins, epoxy of 0.2-0.5, or HG-2 type solidifying agent, and the former is a heat-curing type, and the latter is a quick-dry type.Both temperature classifications, electric and mechanical property does not have significant difference.
