There are many examples being used alone, but these three ingredients are (3-5): (1-2): (1-2's) according to mass ratio
Not, and why applicant selects these three ingredients to be worthy of careful study to example, is obtained by many experiments, N- benzene
Base-beta-naphthylamine has to the good protection effect of the ion of poisonous metal；N- phenyl-N'- isopropyl-p-phenylenediamine is to ozone tortoise
Split, flex crack protective performance it is preferable；And 4,4' a pair ofs (2,2- dimethyl benzyl) diphenylamines can efficiently promote all kinds of rubbers
Therefore the environmental stress resistance of glue product is prevented experienced point and used time, not only having can be reduced its dosage but also capable of having improved protection effect when above-mentioned,
Play it is respective prevent old advantage, greatly improve the service life of silicon rubber protection pipe, be quite suitable for the invention material system；
If the ingredient of complex antiager of the present invention or/and the change of content, will lead to beneficial effects of the present invention cannot be good
It realizes, and has embodiment in above-mentioned comparative example 3.
(3) composite coupler: it is silane series coupling agent that electric power cable, which protects the common coupling agent of tube material, 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 protection pipe beneficial effect is unsatisfactory, therefore, Shen
It asks someone and have passed through a large amount of experiment, unexpectedly obtain tin coupled SSBR and vinyl three ('beta '-methoxy ethyoxyl) silane
And with the composite coupler of synthesis, the beneficial effect that this kind of composite coupler obtains is very prominent, considerably beyond other types and
The coupling agent assembled, it can efficiently niobium yttrium mine tailing, high-speed rail microballon be filled to polymer in adhesion promotion raw material, are improved above-mentioned
The physical property of filler and protection materials interface are damaged from environmental stress.If the ingredient of composite coupler 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 protection pipe of the present invention, remaining of the invention component selection and
Content selection is obviously also non-obvious, and 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 protection pipe of the present invention, in conjunction with the embodiment of the present invention it can be seen that, system of the invention
Using three step designs raw material is added, according to production material property settings technological parameter, step is simple in Preparation Method by several times in batches
And it is orderly, rather than (such as comparative example 5) is added at one time using prior art routine, this technique is and protection pipe of the present invention
What the special proportion of raw materials for production component was adapted, this technique is only used, just can guarantee protection pipe material reaction system
Smooth sequential carries out, and ensures the protection pipe 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.
