[0016] The present invention provides a kind of preparation method of aviation high toughness cable, wherein, described preparation method comprises:
[0017] 1) Stir and mix the fiber, nano-calcium carbonate, tetrahydrofuran and ethanol at a temperature of 120-140°C under the condition of nitrogen protection, and then take the precipitate M1;
[0018] 2) mixing chloroprene rubber and butadiene rubber to obtain mixed rubber M2;
[0019] 3) mixing the precipitate M1, the mixed rubber M2, phosphate, rare earth oxide and anti-aging agent, and then pressing it into a tablet to form a film prototype M3;
[0020] 4) Vulcanize the film prototype M3 prepared above with a vulcanizing agent to obtain a film M4;
[0021] 5) Coating the film M4 prepared above with a metal wire to obtain a high toughness cable for aviation.
[0022] In the present invention, the fiber, nano-calcium carbonate, tetrahydrofuran and ethanol are reacted at a certain temperature under the condition of nitrogen...
