Application performance is more preferable, and useful life longevity is longer.
In conjunction with the excellent effect of the present invention, applicant is illustrated the constituent part and preparation method of the present invention:
(1) composite flame-retardant agent;Zinc borate is common inorganic combustion inhibitor, and originally, applicant singly utilizes it as the present invention's
When fire retardant, the effect that discovery obtains is not obvious, and finally by many experiments, is had been surprisingly found that organic matter tricresyl phosphate (2,3-
Two chloropropyls) ester, phosphoric acid (2- ethylhexyls)-diphenyl ester and zinc borate be according to mass ratio (1-2):(1-2):(2-3) combination profit
Fire retardant more conforms to the material system of the present invention, and finished sheath tube material is enabled to have excellent high temperature resistant
Property and anti-flammability;In development process, it is found for example that as other inorganic combustion inhibitors such as aluminium hydroxide, iron oxide red and above two have
The effect that the present invention is not achieved, the even change of organic matter and each component content is used in combination in machine object, and can not achieve
The technique effect of the present invention has unobviousness.
(2) complex antiager;Applicant has been surprisingly found that the association of antioxidant 4010NA and antioxidant MB in development process
With being used in combination, more suitable for protecting pipe material preparation reaction system of the invention, above two composition is used according to quality
Than (3-5):(2-3) is blended utilization, can significantly improve the inoxidizability, stability and service life of product;If this kind
The content ratio of each composition changes in complex antiager, then can lead to the decline of protecting pipe material property;If this kind compound anti-
In old agent, antioxidant 4010NA or antioxidant MB are substituted for antioxidant 264, antioxidant 4020 etc., can cause the present invention
Advantageous effect cannot be realized preferably.
(3) composite vulcanizing agent;Zinc oxide, sulphur, dual-tert-butyl peroxy isopropyl base benzene are provided with certain cross-linking vulcanized work
With, but in order to adapt to the formation of reaction system of the invention, applicant dexterously uses above-mentioned composition according to mass ratio (1-2):
(1-3):(3-5) collaborative combination uses, and preferably makes to realize cross-linking reaction between raw material, and then reach space network, not only
The mechanical performance of sheath tube material is significantly improved, the stability of product is also preferably improved, service life greatly prolongs;If
It is the change of certain composition and its content in this kind of composite vulcanizing agent, can influences the embodiment of advantageous effect of the present invention.
(4) composite coupler:Silane series coupling agent is most common coupling agent in cable material preparation process, is most being started
Research and development in, applicant is the coupling agent separately as the present invention by it, but obtained finished sheath tube material performance is inadequate
It is ideal, it is difficult to reach beneficial effects of the present invention, then, applicant after considering various reasons, determine to change coupling agent at
Part, look for another way, using rare-earth coupling agent as the present invention coupling agent because its not only Costco Wholesale is cheap, but also very fit
The preferably reaction preparation system of the present invention, it is possible to which obtaining effect can get well than silane series coupling agent, however coupling agent obtains after improving
To the advantageous effect that obtains of finished sheath tube material do not highlight, later, applicant is again unexpected to expect tin coupled SSBR, passes through
By tin coupled SSBR and rare-earth coupling agent, cleverly collaborative combination uses, and obtains unexpected effect so that finished product cable
Sheath tube material has in mechanical properties to be obviously improved, and the combination of above-mentioned composition is non-obvious.
Certainly, because of the requirement of the mentality of designing and goal of the invention of cable jacket tube material of the present invention, remaining group of the invention
Component selections and content selection are obviously also non-obvious, and those skilled in the art combine the prior art that can think easily absolutely not
It arrives.This has further embodiment in the preparation method of sheath tube material of the present invention, in conjunction with the embodiment of the present invention it can be seen that,
The preparation method of the present invention is designed using I-III three step, and raw material is added by several times in batches, and step is simple and orderly, rather than is used
The prior art is conventional to be added at one time, and this technique is the special proportioning phase with sheath tube material raw materials for production component of the present invention
It adapts to, only uses this technique, just can guarantee the excellent specific property for the sheath tube material finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference 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 recorded in example is modified or equivalent replacement of some of the technical features.All essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
