For technical scheme of the present invention, inventor has carried out mould to the cable material prepared using different weight part raw material
Quasi- experiment, test result are as shown in the following Table 1.
The simulation test table of comparisons of cable material prepared by 1 different weight part raw material of table
Wherein：The cable material of experiment 1 to experiment 9 is the raw material and through the invention using different weight part in the present invention
Preparation method be prepared；Then cable material is made to the tablet rubber of 1.8~2.2mm after compression molding, in temperature
88 hours are placed in the environment that degree is 21~25 DEG C, humidity is 40~60%, tablet rubber sample preparation is finally grown into 99.8~
The sample that 100.2mm, width are 9.8~10.2mm, thickness is 1.8~2.2mm is tested.
Experiment 10 using different weight part in the present invention raw materials, in the raw rubber mill 5~raw material is added after ten minutes, and
Sample preparation is carried out after mixing at a temperature of 50 DEG C or so；It is subsequently placed to vulcanizing press to be vulcanized, sulfide stress
120T, 110 DEG C, vulcanization time 10min of curing temperature finally obtain the sample of 10 experiments of experiment.
In table 1, ceramic performance -1. indicates that impact strength, ceramic performance -2. indicate three-point bending strength, ceramic
Performance -3. indicates sintering linear shrinkage, ceramic performance -4. indicate mass loss rate；In compression molding performance, OK is indicated
Vulcanization is uniformly full, and NO indicates overcuring or local vulcanized excessive.
Inventor has found through overtesting：
1, according to experiment 2 and 10 comparison of experiment it is found that Ceramic silicon rubber ratio present invention preparation side prepared by common process
Ceramic silicon rubber rigidity higher prepared by method, and material dispersion is poor, local vulcanized phenomenon is serious, there is also toughness in addition
Difference, the shortcomings of tearing strength is low, shrinking percentage is high.
And the cable material made by preparation method using the present invention, there is high fire-retardance, preferable fire resistance, and
Have 2.0mmV0 grade flame retardant effects；In addition in high-temperature calcination, which discharges without toxic and harmful gas, and energy
The ceramic protection layer for enough forming higher mechanical strength effectively improves conducting wire and is exposed to outer short circuit, to make line
Cable can preferably protect conducting wire when fire occurs.
2, according to experiment 1, experiment 2 and experiment 3, with the increase of cosolvent and ceramic powder ratio, the drawing of cable material
It stretches intensity and ceramic performance is continuously improved, but tearing strength and elongation at break can be gradually reduced simultaneously.
With the increase of ceramic powder, the rigidity of material is continuously improved, and ceramic effect is become better and better, but rigidity
Raising can reduce the lear energy of material and anti-surrender ability.For cable material, especially cable material, toughness and
Resilience is more demanding, and the rigidity of material is easy by force very much to be broken off, therefore the toughness of material of experiment 2 is optimal.
3, according to experiment 2, experiment 4 and experiment 5, increase has halogen fire retardant, can improve the toughness of cable material, but simultaneously
Tensile strength can reduce；
And the rigidity of cable material can be improved by increasing halogen-free flame retardants, however according to experiment 2, experiment 5 and experiment 6, nothing
The flame retardant effect of halogen fire retardant is poor, and a large amount of halogen-free flame retardants of need can be only achieved the flame retardant effect of V0 grades, but material at this time
Material rigidity is excessively high, and toughness drastically reduces.
4, according to experiment 2 and experiment 7, the content of vulcanizing agent has a significant impact for the curability of cable material, excessive
Vulcanizing agent can make cable material overcuring or local defect occur.
5, according to experiment 4, experiment 8 and experiment 9, with the increase of sinter additives, cable material rigidly improves, toughness drop
Low, ceramic effect has reached peak at 0.2 part, and the reduction of material tensile toughness can be made by continuing growing.
According to the test result of table 1, in an embodiment of the present invention, it is preferable that using experiment 2 and 8 raw material number and
Cable material prepared by preparation method, fire resistance is more preferable, and the mechanical strength for the excess that burns is more preferably.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
