Embodiment 1
[0028] A kind of shielded cable material, its preparation method comprises the following steps:
[0029] Step (1): Add 12 parts by mass of glycerol tribenzoate to 55 parts of acetone and stir evenly, then add 6 parts of trioctyl phosphate, stir at 70-80°C for 30-60 minutes, and adjust the pH at 8 -9, the temperature dropped to 45°C, added 4 parts of p-toluic acid and 4 parts of isocyanate, kept at 0.15-0.2MPa, 40-50°C for 2-4 hours, then lowered to room temperature, added vinyl triethoxy 6 parts of silane, stirred for 10-20 minutes to obtain plasticizer,
[0030] Step (2): First, clean the steel fibers in an ultrasonic machine. After cleaning, immerse the steel fibers in the roughening solution for 5-10 minutes, and then rinse with cleaning water; then put the steel fibers into the activation treatment solution for activation. Then put the activated steel fiber into the copper plating solution and soak for 10-20 minutes, and the temperature is controlled at 30-40°C to obtain ...
Embodiment 2
[0037] A kind of shielded cable material, its preparation method comprises the following steps:
[0038] Step (1): Add 13 parts by mass of glycerol tribenzoate to 70 parts of acetone and stir evenly, then add 7 parts of trioctyl phosphate, stir at 70-80°C for 30-60 minutes, and adjust the pH at 8 -9, the temperature dropped to 48°C, added 5 parts of p-toluic acid and 3 parts of isocyanate, kept at 0.15-0.2MPa, 40-50°C for 2 hours, then lowered to room temperature, added vinyltriethoxysilane 7 portion, stirred for 10-20 minutes to obtain plasticizer,
[0039] Step (2): First, clean the steel fibers in an ultrasonic machine. After cleaning, immerse the steel fibers in the roughening solution for 5-10 minutes, and then rinse with cleaning water; then put the steel fibers into the activation treatment solution for activation. Then put the activated steel fiber into the copper plating solution and soak for 10-20 minutes, and the temperature is controlled at 30-40°C to obtain coppe...
Embodiment 3
[0046] A kind of shielded cable material, its preparation method comprises the following steps:
[0047] Step (1): Add 14 parts by mass of glycerol tribenzoate to 75 parts of acetone and stir evenly, then add 8 parts of trioctyl phosphate, stir at 70-80°C for 30-60 minutes, and adjust the pH at 8 -9, the temperature dropped to 40-50°C, added 4.5 parts of p-toluic acid and 2.5 parts of isocyanate, kept at 0.15-0.2MPa, 40-50°C for 2-4 hours, then lowered to room temperature, added vinyl triethyl 7 parts of oxysilane, stirred for 10-20 minutes to obtain a plasticizer,
[0048] Step (2): First, clean the steel fibers in an ultrasonic machine. After cleaning, immerse the steel fibers in the roughening solution for 5-10 minutes, and then rinse with cleaning water; then put the steel fibers into the activation treatment solution for activation. Then put the activated steel fiber into the copper plating solution and soak for 10-20 minutes, and the temperature is controlled at 30-40°C...
