Abstract
The present invention provides a halogen-free environmental-friendly elevator balance compensating chain and a preparation method therefor and an application thereof. The compensating chain comprises one or more strands of steel wire rope inner cores and a rubber layer, wherein the rubber layer is prepared from the following raw materials in parts by weight: natural rubber, an ethylene-propylene-diene monomer and an ethylene-octene-pentene copolymer, a maleic anhydride grafted ethylene-acetic acid ethenyl ester copolymer, a maleic anhydride grafted ethylene-octene copolymer, a maleic anhydride grafted ethylene-butene copolymer, high-density filler, epoxy soybean oil, a lubricant and a flame retardant. By combining various copolymers, in particular, the ethylene-octene-pentene ternary copolymer as one of raw materials, the copolymerization effect is better when the rubber layer is prepared; the density of the rubber layer is smaller, so that the molecular surface of the rubber layer is arranged more closely, and the performance of wear resistance and tear resistance can be better.
Description
Technical field
The present invention relates to elevator technology field, particularly relate to a kind of halogen-free environmental elevator balanced compensated chain, also relate to a kind of manufacture method of halogen-free environmental elevator balanced compensated chain, and use the express elevator of this elevator balanced compensated chain.
Background technology
Elevator balanced compensated chain, for connecting car and the counterweight of elevator, is mainly used in the weight balancing hoist ropes and trailing cable, plays poising action to the operation of elevator, requires that it has bearing load large, runs noise little, flexibly the feature such as bending.At present, for the chain of elevator lifting balanced compensated chain, one is use metal light chain, and in the operational process of elevator, mutually directly clash between chain, noise is large, easily gets rusty; Two is metal light chain overcoat one deck plastic jackets, although the shock of chain interannular can be slowed down, but this compensated chain plastics jacket is easy to crack, come off, work-ing life is short, and three is add at metal light interchain to wear the rope made of hemp or wireline, this compensated chain is easy distortion in operational process, come off, work-ing life is short, and noise is large, poor safety performance, can only be applicable to slower elevators.
Recently; the Plastic coated steel chain balanced compensated for elevator lifting has occurred, this compensated chain, based on iron chains, adds the firm plastic protective layer of last layer on the surface of each ring of iron chains; layer is moulded in each chain link Surface coating one deck leaching of this compensated chain, and it is PVC material that layer is moulded in leaching.Each chain link contacts with each other a little or interviews the surface that layer is moulded in leaching, and it can reduce noise when elevator runs.But during this compensated chain traction car, bearing load is large, each chain link is through the slide-bar of vertex, and chain link changes direction of motion, is subjected to displacement and violent distortion between chain link, and layer wear resisting property is moulded in its leaching and resistance to performance of tearing is not good yet.
Such as Chinese patent 0331665.4 discloses a kind of Elevator balance compensation chain and Manufacture Method.It comprises iron chains (1), rubber cylinder (2), layer of fibers (3), above-mentioned iron chains (1) is placed in above-mentioned rubber cylinder (2), and above-mentioned rubber cylinder (2) is wrapped with layer of fibers (3).This manufacture method is: iron chains (1) eliminates rust; Sizing material is expressed in mould to be wrapped on iron chains (1) and makes rubber cylinder (2); Rubber cylinder (2) is inserted mould, then fiber material is expressed in mould be wrapped in rubber cylinder (2) outside surface form layer of fibers (3); After sulfuration, cooling and shaping, deburring arranges and namely makes.When the elevator balanced compensated chain of this technical scheme runs, noise is low, wear resistance good, tear strength and elongation at break high.But this elevator balanced compensated chain making work is complicated, and the auxiliary material of use is more, require higher to starting material, therefore cost of manufacture is higher, and performance does not reach desirable level.
For another example Chinese patent CN104140600A discloses a kind of halogen-free environmental high-speed elevator compensation chain material, it is characterized in that, with parts by weight, the composition of raw materials of described elevator compensation chain material is as follows: ethylene-propylene diene copolymer 40 ~ 60 parts, ethylene-octene copolymer 20 ~ 40 parts, maleated ethylene vinyl acetate copolyme and/or maleic anhydride grafted ethene-octene copolymer 10 ~ 30 parts, high-density stopping composition 250 ~ 450 parts, epoxy soybean oil 15 ~ 25 parts, 1 ~ 2 part, oxidation inhibitor, lubricant 2 ~ 5 parts, wherein: in ethylene-propylene diene copolymer, ethylene content is 60wt% ~ 70wt%, Third monomer content is 2wt% ~ 10wt%, mooney viscosity is 20 ~ 60, the Shore A hardness of described maleated ethylene vinyl acetate copolyme and/or maleic anhydride grafted ethene-octene copolymer is between 65 ~ 85.The hardness about 85 of the elevator balanced compensated chain that this technical scheme provides; Have good intensity and elongation, can ensure that cable is in operation can not rupture; Softness can meet the bending back and forth requirement that elevator runs; By the impact of temperature, greasy dirt erosion, not easy to wear, damage, noise is little, have longer work-ing life.But this elevator balanced compensated chain making work is complicated, and the auxiliary material of use is more, require higher to starting material, therefore cost of manufacture is higher, and performance does not reach desirable level.
