Description

Technical Field

[0001] The utility model belongs to the technical field of phosphating steel wires, and in particular relates to a heat-resistant and flame-retardant phosphating steel wire. Background Art

[0002] The patented technology of phosphate coated steel wire rope, also known as manganese phosphate wear-resistant coated steel wire rope, referred to as phosphated steel wire rope, is to phosphate the rope-making steel wire. The phosphate film makes the steel wire surface more wear-resistant and improves its corrosion resistance. The porous structure of the phosphate film can increase the storage amount of grease on the surface of the rope-making steel wire, reduce the friction factor to promote sliding, delay the occurrence of micro-wear damage on the steel wire surface, and inhibit the initiation of fatigue micro-cracks, thereby greatly extending the service life of the steel wire rope.

[0003] The existing phosphated steel wire is not heat-resistant. When it is partially subjected to high-temperature calcination, it will soften, causing the phosphated steel wire to break easily, shortening the service life of the phosphated steel wire. At the same time, the strength of the phosphated steel wire is insufficient and its bending resistance is poor, causing it to break easily due to excessive bending.

[0004] Therefore, a heat-resistant and flame-retardant phosphated steel wire is needed to solve the problems of poor heat resistance and poor toughness of the steel wire in the prior art. Utility Model Content

[0007] It should be noted in the scheme that the protective layers are respectively a silicon carbide ceramic fiber layer, a manganese phosphating coating, and an alumina ceramic layer from the inside to the outside.

[0008] It is further worth noting that the outer steel wire strand includes a filling layer, the inner wall of the filling layer is provided with outer layer isolation wires in a cross distribution, the inner layer of the outer layer isolation wires is provided with inner layer isolation wires, and the center of the inner layer isolation wires is provided with a second steel wire.

[0009] It should be further explained that the inner steel wire strand includes a flexible rubber layer, the inner wall of the flexible rubber layer is provided with a third steel wire distributed in a circular pattern, a flame retardant layer is provided at the center of the flexible rubber layer, a high-temperature calcium silicate layer is provided on the inner wall of the flame retardant layer, and a fourth steel wire is provided at the center of the high-temperature calcium silicate layer.

[0010] As a preferred implementation, the second steel wire, the fourth steel wire and the third steel wire are made of carbon steel.

[0011] As a preferred implementation, the first steel wire is a high-strength polyester fiber steel wire.

[0012] Compared with the prior art, the heat-resistant and flame-retardant phosphating steel wire provided by the utility model has at least the following beneficial effects:

[0013] (1) The alumina ceramic layer can withstand high temperatures and has excellent thermal insulation and corrosion resistance. The manganese phosphating coating is made of calcium silicate, which can resist high temperatures and corrosive substances and has high pressure resistance. At the same time, the silicon carbide ceramic fiber layer can further withstand high temperatures and has good mechanical properties, corrosion resistance and low thermal capacity, making the heat resistance of the steel wire even better.
