preparation example Construction

[0015] The invention provides a method for preparing an anti-corrosion and oil-resistant cable, wherein the preparation method comprises:

[0016] 1) Mixing silicon dioxide in an acid solution to obtain acid-etched silicon dioxide;

[0017] 2) In the presence of a solvent, the acid-etched silicon dioxide and nano-zinc oxide are mixed and filtered to obtain a mixture M1;

[0018] 3) mixing and melting polypropylene resin, mixture M1, polyurethane resin, mica powder, magnesium oxide, curing agent and accelerator, and extruding to obtain a wire sheath;

[0019] 4) Coating the wire sheath with the wire core to obtain an anti-corrosion and oil-resistant cable.

[0020] In the present invention, silicon dioxide is mixed in acid solution, then mixed with nanometer zinc oxide, filtered, and then polypropylene resin, mixture M1, polyurethane resin, mica powder, magnesium oxide, curing agent and accelerator are mixed and smelted and extruded forming to obtain a wire sheath, and then w...

Embodiment 1

[0031] 1) Put 30 parts by weight of silicon dioxide in 100 parts by weight of an aqueous solution of hydrochloric acid (the content of hydrochloric acid is 35% by weight) and stir and mix at a temperature of 40° C. to prepare silicon dioxide after acid etching;

[0032] 2) In the presence of water, 10 parts by weight of acid-etched silicon dioxide and 3 parts by weight of nano-zinc oxide are mixed and filtered to obtain a mixture M1;

[0033] 3) 100 parts by weight of polypropylene resin, 30 parts by weight of mixture M1, 50 parts by weight of polyurethane resin, 3 parts by weight of mica powder, 5 parts by weight of magnesium oxide, 1 part by weight of curing agent and 1 part by weight of accelerator are placed at a temperature of After mixing and melting at 180°C, extrusion molding is made to obtain the wire sheath;

[0034] 4) Cover the wire core with the wire sheath to prepare the anti-corrosion and oil-resistant cable A1.

Embodiment 2

[0036] 1) Put 50 parts by weight of silicon dioxide in 100 parts by weight of an aqueous solution of hydrochloric acid (the content of hydrochloric acid is 35% by weight) and stir and mix at a temperature of 60° C. to prepare silicon dioxide after acid etching;

[0037] 2) In the presence of water, 10 parts by weight of acid-etched silicon dioxide and 5 parts by weight of nano-zinc oxide are mixed and filtered to obtain a mixture M1;

[0038] 3) 100 parts by weight of polypropylene resin, 60 parts by weight of mixture M1, 60 parts by weight of polyurethane resin, 10 parts by weight of mica powder, 20 parts by weight of magnesium oxide, 5 parts by weight of curing agent and 5 parts by weight of accelerator are placed at a temperature of After mixing and melting at 220°C, extrusion molding is made to obtain the wire sheath;

[0039] 4) Cover the wire core with the wire sheath to prepare the anti-corrosion and oil-resistant cable A2.

Abstract

The invention discloses an anti-corrosive oil-resisting cable and its preparation method. The preparation method includes steps of 1), placing silicon dioxide in acid fluid to mix, and preparing the silicon dioxide after acid erosion; 2), mixing and filtering the silicon dioxide after acid erosion with nano-zinc oxide in the presence of solvent, and preparing a mixture M1; 3), mixing and melting polypropylene resin, the mixture M1, polyurethane resin, mica powder, magnesium oxide, curing agent and accelerant, and then extruding and shaping; preparing a cable skin; 4), coating a cable core by the cable skin, and preparing the anti-corrosive oil-resisting cable. Through the methods of placing silicon dioxide in acid fluid to mix, mixing and filtering the silicon dioxide, and then mixing andmelting polypropylene resin, the mixture M1, polyurethane resin, mica powder, magnesium oxide, curing agent and accelerant, and then extruding and shaping to prepare the cable skin, and coating the cable core by the cable skin, the cable has good oil-resisting and anti-corrosive performances.

Description
