Table 7
By upper table 6 and table 7, it can be concluded that, insulating materials of the invention is in electric property, mechanical performance and freeze proof resistance to old
It is promoted significantly in the property changed, comprehensive performance is more excellent, and application field occasion is more extensive, long service life.
In conjunction with the beneficial effect of the present invention, applicant illustrates constituent part and preparation method of the invention as follows:
(1) complex antiager；6- ethyoxyl -2,2,4- trimethyl -1,2- dihyaroquinoline, N- phenyl-N'- isopropyl -
P-phenylenediamine, 4,4' a pair of (2,2- dimethyl benzyl) three kinds of ingredients of diphenylamines all have the anti-aging effect of different characteristics,
The many examples being used alone are had existed in the prior art, but these three ingredients are (3-5) according to mass ratio:
(1-2): not, and why applicant selects these three ingredients to be worthy of careful study to the example of (1-2), is by a large amount of
Experiment obtains, 6- ethyoxyl -2,2, and 4- trimethyl -1,2- dihyaroquinoline thermo oxidative aging performance is strong；N- phenyl-N'- is different
Propyl-p-phenylenediamine is good to ozone-induced cracking, flex crack protective performance；And 4,4' a pair ofs (2,2- dimethyl benzyl) diphenylamines energy
Therefore enough environmental stress resistances for efficiently promoting all kinds of rubber products prevent experienced point and used time when above-mentioned, both can be reduced its dosage
Protection effect can be improved again, and performance is respective to prevent old advantage, greatly improves the service life of Electric insulation material, is quite suitable for
Material system of the invention；If the ingredient of complex antiager of the present invention or/and the change of content, will lead to of the invention has
Beneficial effect cannot be realized well, and have embodiment in above-mentioned comparative example 2.
(2) composite coupler: the common coupling agent of electric power insulating polymeric material is silane series coupling agent, for that will have
Machine macromolecule and inorganic filler reaction fusion, applicant are initially to make vinyl three ('beta '-methoxy ethyoxyl) silane list composition
It is added to for coupling agent in material system of the invention, but obtained finished product insulating materials beneficial effect is unsatisfactory, therefore,
Applicant have passed through a large amount of experiment again, unexpectedly obtain aluminum-zirconium bimetallic coupling agent and (the 'beta '-methoxy second of vinyl three
Oxygroup) silane and with the composite coupler of synthesis, the beneficial effect that this kind of composite coupler obtains is very prominent, considerably beyond it
His type and the coupling agent assembled, it can efficiently calcium titanium mine tailing, ferric trichloride be filled to polymer in adhesion promotion raw material,
The physical property and protection materials interface for improving above-mentioned filler are damaged from environmental stress.If composite coupler of the present invention at
Point or/and content change, will lead to beneficial effects of the present invention cannot realize well, and have in above-mentioned comparative example 3
It embodies.
(3) cross-linking aid: rubber insulation material mostly uses cumyl peroxide to carry out in existing preparation process
Vulcanization crosslinking, but with the development of material science, material system of the present invention makes peroxidating diisopropyl to vulcanization crosslinking demand
Benzene list composition is difficult to meet, and therefore, applicant has developed a kind of novel compounding cross-linking aid, this kind specifically for the present invention
Cross-linking aid is cooperateed with and is used in combination by three kinds of cumyl peroxide, polyethyleneglycol diacrylate, divinylbenzene ingredients, can be very
Beneficial effects of the present invention and purpose are realized well, can make quickly to be formed between framework strand in insulating materials of the present invention
Largely and the bridged bond that is evenly distributed, the 3 D stereo reticular structure being built into is form compact and stable, and the collaboration of the other raw materials of compatibility is made
With the physical property and stability of material can be significantly improved.If the ingredient of cross-linking aid of the present invention or/and the change of content,
Will lead to beneficial effects of the present invention cannot realize well, and have embodiment in above-mentioned comparative example 4.
Certainly, because of the requirement of the mentality of designing and goal of the invention of insulating materials of the present invention, remaining component selection of the invention
And content selection is obviously also non-obvious, those skilled in the art combine the prior art that can readily occur in absolutely not.This
Have further embodiment in the preparation method of insulating materials of the present invention, in conjunction with the embodiment of the present invention it can be seen that, the present invention
Preparation method using the design of three steps, raw material is added by several times in batches, according to production material property settings technological parameter, step
It is simple and orderly, rather than use the prior art is conventional to be added at one time (such as comparative example 5), this technique is exhausted with the present invention
What the special proportion of edge material raw materials for production component was adapted, this technique is only used, just can guarantee insulating materials reactant
The smooth sequential of system carries out, and ensures the electric insulation product excellent characteristics finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
