Embodiment 1

[0030] Embodiment 1: a kind of special fireproof rope, such as figure 1 , figure 2 As shown, the special fireproof rope is a double-structure braided rope, including a rope core 1 and an outer covering layer 2. The rope core 1 is braided by 12 inner core strands, and the inner core strands are made of ultra-high molecular weight polyethylene fibers. The outer covering layer 2 is braided by 24 outer covering rope strands, the material of the outer covering rope strands is polycrystalline refractory fiber, and the outer covering layer 2 is tightly wrapped on the surface of the rope core 1 .

Embodiment 2

[0031] Embodiment 2: a kind of special fireproof rope, such as image 3 , Figure 4 As shown, the difference from Embodiment 1 is that the rope core 1 is braided by three inner core strands, and the material of the inner core strands is polyester fiber.

Embodiment 3

[0032] Embodiment 3: a kind of special fireproof rope, such as Figure 5 , Figure 6 As shown, the difference from Embodiment 1 is that the rope core 1 is braided by 8 inner core strands, and the material of the inner core strands is polyamide fiber.

Abstract

The invention discloses a special fireproof rope. The special fireproof rope comprises a rope core and an outer coating layer, wherein the outer coating layer is made of polycrystalline fire-resistant fibers; and the rope core is made of one of polyamide fibers, polyester fiber and ultra-high molecular weight polyethylene fibers. The special fireproof rope has the advantages and effects that the rope core is made of the polyamide fibers, the polyester fiber or the ultra-high molecular weight polyethylene fibers, the outer coating layer is made of the polycrystalline fire-resistant fibers with excellent heat insulation and flame retardation properties, the special fireproof rope is formed, and therefore, the special fireproof rope has excellent flame retardation property and high strength, and can be used for fire rescue and escape of people in high-rise buildings.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a special fireproof rope. Background technique [0002] With the development of urban construction in our country, there are countless large-scale high-rise buildings, followed by various safety hazards. Among various disasters, fire is one of the most frequent and common low-threat threats to public safety and social development. One, when a fire breaks out in a high-rise building, the people in the building need to escape from the high-rise building by means of a fire rope. [0003] The Chinese patent "Fiber Rope for Fire Fighting and Its Preparation Method" with the authorized announcement number CN103510412A discloses a fiber rope for fire fighting, which includes a part of polyacrylonitrile pre-oxidized fiber strands with S twist direction, and another part of polyacrylonitrile pre-oxidized fiber strands. The oxidized fiber strands are rope sheaths braided in the Z twist direction and ...
