Description

Technical Field

[0001] The present invention relates to the field of braided ropes, and more particularly to a polyethylene multi-strand composite braided rope. Background Art

[0002] A polyethylene rope is a polyethylene rope that can withstand high-temperature environments, and it has a relatively high melting point and heat resistance. High-temperature polyethylene ropes are commonly used in high-temperature working scenarios, such as the metallurgy and oil refining industries, and can maintain stability and safety in high-temperature environments. After searching, the prior art (application number: CN202122298698.8) records that "through the mutual cooperation of the elastic layer and the connecting sleeve, the flame-retardant layer is fixed at the central position of the elastic layer and the connecting sleeve, and the elastic layer and the fixing sleeve are used to isolate and protect the flame-retardant layer. The elastic effect of the elastic layer can effectively prevent the impact of the external force, ensuring the overall toughness of the composite rope and preventing the fracture of the flame-retardant layer from reducing the flame-retardant ability of the rope." However, in the prior art, both the flame-retardant layer and the elastic layer produce harmful gases when burned, which is harmful to human health. Summary of the Invention

[0003] To overcome the defects of the prior art, the present invention provides a polyethylene multi-strand composite braided rope to solve the problem that both the flame-retardant layer and the elastic layer in the prior art produce harmful gases when burned, which is harmful to human health.

[0004] To achieve the above object, a polyethylene multi-strand composite braided rope is provided, including: a braided rope body, A rope core is arranged inside the braided rope body. The outer surface of the rope core is braided with polyethylene rope strips, nano rope strips, and polyarylate rope strips. An inorganic fiber layer is wrapped outside the polyethylene rope strips, nano rope strips, and polyarylate rope strips. A nylon outer layer is wound around the outer surface of the inorganic fiber layer.

[0005] Further, the polyethylene rope strips, nano rope strips, and polyarylate rope strips are alternately braided outside the rope core.

[0006] Further, an adhesive layer is coated on the outer surface of the rope core; and the adhesive layer is adhered to the polyethylene rope strips, nano rope strips, and polyarylate rope strips.

[0007] Further, the rope core is an elastic rubber strip placed at the middle inside the braided rope body.

[0008] Further, nano magnesium hydroxide filler is mixed and added into the nano rope strips.

[0009] Further, the polyethylene rope strips, nano rope strips, polyarylate rope strips, and the rope core form a multi-strand composite braided rope body.

[0010] Furthermore, the inorganic fiber layer is reticularly attached to the inner side of the nylon outer layer.

[0011] The beneficial effects of the present invention are as follows. The polyethylene multi-strand composite braided rope of the present invention is formed by braiding and winding polyethylene rope strips, nano rope strips, and polyaryl ester rope strips to form a multi-strand composite braided rope. The inorganic fiber layer is wrapped around the outer side of the multi-strand composite braided rope to achieve an environmentally friendly flame-retardant polyethylene multi-strand composite braided rope, which is convenient for preventing the outer flame from burning the inner braided rope strips, avoiding the generation of harmful gases during flame retardancy, and improving the environmental friendliness and durability of the multi-strand composite braided rope.
