Example Embodiment
[0025] Example 1
[0026] This embodiment relates to a corrosion-resistant and flame-retardant cable material, including the following raw materials by weight: 20 parts of low-density polyethylene, 10 parts of natural rubber, 8 parts of polypropylene, 12 parts of ethylene-vinyl acetate copolymer, and modified talc. 6 parts of powder, 2 parts of zinc borate, 3 parts of antimony trioxide, 1 part of calcium stearate, 2 parts of polyethylene wax, 2 parts of coupling agent, 1 part of antioxidant, 2 parts of antioxidant.
[0027] Wherein, the preparation method of described modified talc is as follows:
[0028] (1) Weigh talc, bentonite, jade powder and boron mud in a weight ratio of 6:3:2:1 and mix them evenly to obtain a mixture;
[0029] (2) To the mixture obtained in step (1), add 1.5% of triethanolamine, 2% of sodium polyacrylate, 1.5% of calcium lignosulfonate, 0.6% of vinyl tris (β-methoxyl group) by total weight. Ethoxy) silane, high-speed grinding at 2000rpm for 15min, dr...
