Description
Technical field
The present invention relates to a kind of steel cable core conveying belt, specifically a kind of cold-resistant fire-retardant steel cable core conveying belt.
Background technology
Steel cable core conveying belt is mainly used in heavy duty, remote mass transport; The steel cable core conveying belt of prior art mainly contains general applications steel cable core conveying belt (GB/T9770-2001), colliery wire rope core fire retarding conveying band (MT668-2008); The former is used for the conveying of common material; Neither fire-retardant, also not cold-resistant.The latter is used for the conveying of colliery underground coal, has fire-retardant and antistatic property, but not cold-resistant.The open coal mine of northeast, the Northwest uses the Steel cord fire retarding conveying band in a large number; Because the temperature in winter is everlasting below-40 ℃, even is lower than-60 ℃, and the permission environment for use range of temperatures of the Steel cord fire retarding conveying band of prior art is-10 ℃-40 ℃; In case ambient temperature is lower than-10 ℃; Can make the rubber cover hardening, reduce the elasticity and the groove forming character of load-transfer device, effect and service life are carried in influence.When ambient temperature is lower than-30 ℃, can make that rubber cover sharply becomes fragile, shattered crack, the binding power of steel rope and rubber reduces significantly, has a strong impact on to carry effect and service life.Thereby the Steel cord fire retarding conveying band of prior art can not satisfy the operating needs of extremely frigid zones open coal mine.
Summary of the invention
In order to satisfy the operating needs of extremely frigid zones open coal mine, the invention provides a kind of cold-resistant fire-retardant steel cable core conveying belt, both met the requirement of MT668-2008 " colliery wire rope core fire retarding conveying band ", again can long-term use under-60 ℃ of environment.
The technical scheme that the present invention takes is: a kind of cold-resistant fire-retardant steel cable core conveying belt is provided; Comprise Steel cord, intermediate gelatine layer, last covering glue layer, following covering glue layer; It is characterized in that; Described upward covering glue layer, following covering glue layer are cold-resistant fire-retardant polysulphide rubberss, and sizing compound formula is by weight:
India rubber 30-50 part, butadiene rubber 25-35 part, chlorinated scoline 25-35 part, Sulfur 1-2 part; Zinc oxide 6-8 part, stearic acid 1-2 part, accelerator 2-4 part, aging inhibitor 2-4 part; Paraffin 1-2 part, conductive black 8-15 part, high wear-resistant carbon black 25-35 part; Solid flame retardant 25-55 part, liquid flame retardant 15-25 part, flame-resistant lubricant 5-10 part.
In the prescription of said sizing material, accelerator can select for use dibenzothiazyl disulfide, zinc diethyl dithiocarbamate, zinc dibutyl dithiocarbamate, 2-benzothiazolyl mercaptan, N-to encircle ethyl-2-[4-morpholinodithio sulfenamide, tetramethylthiuram disulfide or its combination; Aging inhibitor can select 2,2 for use, 4-trimethyl-1,2-dihyaroquinoline, N-PBNA, N-PA, 2,2
,,-di-2-ethylhexylphosphine oxide (4-methyl-6-tert butyl phenol), N-isopropyl-N
,-phenyl is to aniline or its combination; Solid flame retardant can be selected antimony oxide, deca-BDE, Firebrake ZB, APP, 70% chlorinated paraffin or its combination for use; Liquid flame retardant can be selected triaryl phosphate, three (β-chloroethyl) phosphate, three (3,2-two chloropropyls) phosphate, 45% chlorinated paraffin, 52% chlorinated paraffin or its combination for use; Flame-resistant lubricant can be selected MB-202, MCA-2 for use.
For realizing cold-resistant effect better, between described intermediate gelatine layer and the last covering glue layer and between intermediate gelatine layer and the following covering glue layer layer of glass canvas heat-insulation layer is being set respectively.
At first through plasticate, mixing, upper and lower rubber cover, middle glue film are processed in calendering or fibrous glass is wiped the rubberizing canvas; Through the flat board of colding pressing upper and lower rubber cover, intermediate film, steel rope or fibrous glass are wiped rubberizing canvas cold isostatic compaction together then, at last logical vulcanizing press sulfidization molding under permanent tension state.
Advantage of the present invention and beneficial effect are: 1, described upper and lower covering glue layer have good cold tolerance and flame retardance, can guarantee not delamination under-60 ℃ of low-temperature conditions, not chap, do not harden, do not become fragile, can long-term use.2, because at upper and lower rubber cover and contain between the middle glue of Steel cord and respectively laid layer of glass canvas heat-insulation layer; And fibrous glass has good heat-insulating property; Thereby can stop Cryogenic air effectively to middle glue and wire rope transfers; Guaranteed that the bonding strength between steel rope under the psychro-environment temperature and middle glue does not descend; Thereby solved effectively of the prior artly come unstuck, problem, cold tolerance, flame retardance, conveying effect and the service life of having improved load-transfer device such as embrittlement, change split.
