Embodiment approach 1

[0038] Embodiment 1: The polyvinyl chloride sheath can use 95 parts of polyvinyl chloride resin, 45 parts of dioctyl phthalate (DOP), 1 part of epoxy soybean oil (ESO), and 1 part of calcium-zinc composite Stabilizer, 1 part of processing aid, 0.1 part of antioxidant, 35 parts of calcium carbonate (live light), 1 part of flame retardant, 1 part of rodent control agent, 1 part of anti-termite agent, 1 part of ZnO·B2O3·2H2O, 15 parts of Al(OH)3. The polyvinyl chloride sheath made of the raw materials designed above has the effects of anti-rat, anti-termite, low-smoke and low-halogen, lead-free and flame-retardant.

Embodiment approach 2

[0039] Embodiment 2: The polyvinyl chloride sheath can use 105 parts of polyvinyl chloride resin, 55 parts of dioctyl phthalate (DOP), 8 parts of epoxy soybean oil (ESO), and 8 parts of calcium-zinc composite Stabilizer, 5 parts of processing aid, 0.3 part of antioxidant, 45 parts of calcium carbonate (live light), 5 parts of flame retardant, 5 parts of rodent control agent, 5 parts of anti-termite agent, 3 parts ZnO·B2O3·2H2O, 25 parts of Al(OH)3. The polyvinyl chloride sheath made of the raw materials designed above has the effects of anti-rat, anti-termite, low-smoke and low-halogen, lead-free and flame-retardant.

Embodiment approach 3

[0040] Embodiment 3: The polyvinyl chloride sheath can use 100 parts of polyvinyl chloride resin, 50 parts of dioctyl phthalate (DOP), 5 parts of epoxy soybean oil (ESO), and 5 parts of calcium-zinc composite Stabilizer, 3 parts of processing aids, 0.2 parts of phenolic antioxidant, 40 parts of calcium carbonate (living light), 3 parts of Sb2O3 flame retardant, 3 parts of environmentally friendly capsaicin rodent-proof agent, 3 parts cypermethrin low toxicity anti-termite agent, 2 parts of ZnO·B2O3·2H2O, 20 parts of Al(OH)3. The polyvinyl chloride sheath made of the raw materials designed above has the effects of anti-rat, anti-termite, low-smoke and low-halogen, lead-free and flame-retardant.

Abstract

The invention relates to the technical field of cables and in particular relates to a cable for elevators, and provides a rat-proof termite-proof low-smoke low-halogen leadless flame-retardant control cable for elevator shafts, which comprises a sheath and a cable core arranged in the sheath, wherein the cable core comprises a conductor and an insulating layer arranged outside the conductor, the sheath is a polyvinyl chloride sheath made of a polyvinyl chloride insulating material, and the polyvinyl chloride insulating material has rat-proof, termite-proof, low-smoke, low-halogen, leadless and flame-retardant properties. By using the technical scheme, the cable has the rat-proof, termite-proof, low-smoke, low-halogen, leadless and flame-retardant effects, and also has the advantages of flexibility, elasticity and firm structure.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable used for elevators. Background technique [0002] The cores of today's elevator cables are mostly composed of steel wires, nylon ropes and fibers. The sheath is made of PVC material. Although the tensile strength and flexibility are very strong, it cannot prevent the bite of white mice and termites, nor can it prevent the burning of flames. [0003] When there is a fire situation, the sheath is easy to burn, and the gas produced by the combustion will contain toxic gases such as halogens. After the human body inhales these toxic gases, it will cause suffocation and death in a short period of time, reducing the chance of people escaping in a fire. In addition, because gases containing corrosive components such as halogens are likely to be generated during a fire, they can cause corrosion to buildings, equipment, instruments, etc., and cause secondary losses.
