Detect example 1
In embodiment 1-3 and comparative example 1-2, it is divided into activity duration and actual operating time.Activity duration is according to system
The effective operation time that Preparation Method carries out, and actual operating time includes because cleaning sticks the time of the shutdown such as roller, for from going into operation
To the total time for preparing completion.
In sheath preparation process, the mixing situation in embodiment 1-3 and comparative example 1-2 is observed, to occurring sticking roller phenomenon
Cleaning is shut down in time, continues operation after cleaning, downtime is not counted in the activity duration.
It was found that in embodiment 1-3, comparative example 2, substantially without glutinous roller phenomenon, material is uniform, mixes all right, embodiment 1-
3, the activity duration in comparative example 2 is actual operating time.And in comparative example 1, repeatedly occur sticking roller phenomenon, phenomenon is material
At bulk, sticking cannot fall on roller, need operating personnel repeatedly to shut down and clear up, according to statistics, the practical behaviour in comparative example 1
Making the time increases 50% than activity duration, and operating efficiency is obviously low.Repeatedly occur sticking roller phenomenon in comparative example 3, phenomenon is object
Expect into bulk, sticking cannot fall on roller, need operating personnel repeatedly to shut down and clear up, according to statistics, the reality in comparative example 1
Operating time increases 40% than activity duration, and operating efficiency is obviously low.
Detect example 2
Composite cable sealing sheath material in embodiment 1-3 and comparative example 1-3 is according in national standard GB/T1040-2006
Method tested for tensile strength, the AG-20KNG of puller system model Shimadzu Corporation production；Rate of extension is 500mm/min, test
Temperature is 23 DEG C.According to the composite cable sealing sheath material in GB/T 2423-2001 testing example 1-3 and comparative example 1-2
Maximum operating temperature.
It was found that tensile strength is relatively uniform between each sample of composite cable sealing sheath material in embodiment 1-3, not only
In this way, tensile strength is also superior to the tensile strength in comparative example 1-3.Specifically, the tensile strength highest in embodiment 3, can reach
To 23.8N/mm2, the tensile strength in embodiment 2 is better than embodiment 1, and the tensile strength in embodiment 1 is 22.1N/mm2.And it is right
The tensile strength of sample is very uneven in ratio 1,3, and especially highest tensile strength can reach 22.2N/ in comparative example 1
mm2, still, the tensile strength of individual sample is very low, only 18.8N/mm2, the tensile strength in comparative example 3 can reach 22.5N/
mm2, minimum for 20N/mm2；Although the tensile strength of the sample in comparative example 2 is uniform, relatively low, highest only 18.5N/
mm2。
Moreover, the maximum operating temperature of each sample in embodiment 1-3, comparative example 2 is between 105-120 DEG C,
And the maximum operating temperature difference of the sample in comparative example 1,3 is larger, and it can be up to 113 DEG C although highest, minimum is only
85℃。
It can be seen that the present invention not only solves the glutinous roller phenomenon in preparation process, and obtained composite cable
The tensile strength and heat resistance of sealing sheath material are preferable, and the performance of sample is more uniform, this is kneaded in preparation process
It is even make it is inseparable.
And stick roller phenomenon in comparative example 1,3 and repeatedly occur, the compound electric for causing actual operating time not only to be grown, but also obtaining
The tensile strength and heat resistance of cable sealing sheath material are uneven, the tensile strength some of sample have greatly it is small, this with preparing
Raw material is blocking in the process, cannot be uniformly mixed and be undivided.Moreover, although addO-on therapy is not much different with embodiment 3,
But the tensile strength of sample and maximum operating temperature are traced it to its cause compared with being declined in embodiment 3, it may be possible to practical behaviour
The extension for making the time, causes raw material to be cracked in high fever.
Although and the not glutinous roller in preparation process of comparative example 2, the tensile strength of sample are relatively low, it is seen then that simple tune
The additive amount for saving solvent, can not obtain the composite cable sealing sheath material of better performances.
The preferred embodiment of the present invention has been described above in detail, still, during present invention is not limited to the embodiments described above
Detail can carry out a variety of simple variants to technical scheme of the present invention within the scope of the technical concept of the present invention, this
A little simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the present invention to it is various can
The combination of energy no longer separately illustrates.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should also be regarded as the disclosure of the present invention.
