1) 4 parts of 5 parts of aluminium nitride and silicon nitride are poured into nano grinder together and carry out pulverization process, nano powder is made End, it is standby；
2) 54 parts of polysiloxanes and appropriate moisture are poured into reactor together and are heated to 100 DEG C or so, Ran Houjia Enter 14 parts of sulphur, and continue to be heated to 165 DEG C, thick liquid is made, it is standby；
3) by 110 DEG C of thick liquid heating water bath made from step 2) and holding so that the company of addition after moisture evaporating completely 17 parts of 4 parts of sodium sulfite and ethylbenzene, are sufficiently stirred, and gluing shape liquid is made, standby；
4) by 6 parts of polycrystalline mullite fibre, 2 parts of magnesium chloride, 3 parts of viscose rayon, 2 parts of polypropylene fibre and glass fibre 5 Part is poured into gluing shape liquid made from step 3) together to be stirred, and paste is made, standby；
5) by paste made from nanometer powder made from 8 parts of strontium chromate, 6 parts of antimony oxide, step 1) and step 4) 4 parts of polyacrylamide of addition after being stirred 3 hours in ultrasonic stirrer is poured into together, is then heated to 350 DEG C, and mixing is made Lotion, it is standby；
6) mixing paste made from step 5) is poured into the mould for being injected into mixing paste in injection moulding machine and having closed Intracavitary, product is obtained after cured sizing, you can use.
Experimental example：
The pre-branched cable of the present invention is surveyed as a control group as experimental group, existing common pre-branched cable Examination, concrete outcome are as shown in the table：
By being detected to 2 groups of experiments, the pre-branched cable of experimental group is electric compared with existing common pre-branched cable Magnetic wave shielding properties and fire protecting performance are outstanding.
Beneficial effects of the present invention are：There is outstanding heat resistance and insulating properties by being provided with fire-proof insulation sheath Can, it can prevent bifurcations from drain conditions occur and cause potential safety hazard, and scribble electromagnetic wave screen paint on clamping Effectively by electromagnetic wave shielding Electromagnetic Wave Propagation can be prevented to the external world, by being provided with single copper on the second branch cable Line, cylindrical silver bar is provided with single copper cash, and cylindrical silver bar is embedded in cylinder shape groove setting so that the second branch cable It can be rotated with the rotation of rubber cap, flexibly and easily, multidirectional cabling can be carried out.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any The change or replacement expected without creative work, it should all be included within the scope of the present invention.
