Abstract
The invention discloses a kind of underground mine use kevlar fabric core fire retarding conveying band, it is made up of upper caldding layer, upper cushion, tensile layer, bottom breaker, lower caldding layer, tensile layer is upper caldding layer above upper cushion, is lower caldding layer below bottom breaker between each one layer of cushion up and down.The fire retarding conveying band of the present invention, the physical and mechanical properties of upper lower caldding layer meet 4.5 requirements in MT668 2008.Inhibiting tape plunger bond strength >=10N/mm.The flame-retarding performance of inhibiting tape meets the requirement of the standards of MT668 2008.
Description
Technical field
The present invention relates to a kind of underground mine use kevlar fabric core fire retarding conveying band, belong to conveyer belt formulation art.
Background technology
Steel wire rope is the critical piece of underground coal mine coal conveying, be mainly suitable for it is long away from
From the Work places of, large conveying quantity.Therefore steel wire rope does not require nothing more than at a relatively high fire resistance, also
Need that there is very high mechanical mechanics property.MT668-2008《Steel wire rope》Standard applies to coal
The highest ranking requirement of the antistatic steel cable core conveying belt product of mining flame-retardant.The standard will to the steel wire rope bonding strength of band
Ask and improve 20%~35% than primary standard MT668-1997, while new standard also add dynamic steel wire rope bonding fatigue resistance
Energy, rubber osmosis performance, static joint stretch breaking strength, the requirement of dynamic joint stretch breaking strength.
The bonding layer sizing of existing steel wire rope is typically using rubber, vulcanizing agent, age resistor, resistance
The materials such as combustion agent, reinforcing agent, adhesive, which are kneaded, is made sizing material, after calendering bottom sheet is compound with rubber cover, is carried out with steel wire rope cold
After overlaying conjunction vulcanization, there is the fire retarding conveying band that steel wire rope does framework material among formation.
As described above, the bonding layer sizing of existing steel wire rope, though have to a certain extent
Certain fire-retardant and bond properties, but sizing material is relatively low to the penetrating power of steel wire rope, and combination property does not reach MT668- much
The requirement of 2008 standards.Substantial amounts of inorganic combustion inhibitor is particularly with the addition of, is disperseed although the method that can be kneaded by multistage improves
Performance, but due to the hydrophily of material surface, inorganic filler is difficult to be dispersed in the discrete phase of rubber hydrocarbon.
The content of the invention
The technical problems to be solved by the invention are：A kind of New Coal Mine underground kevlar fabric core fire retarding conveying band.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
Underground mine use kevlar fabric core fire retarding conveying band provided by the invention, by upper caldding layer, upper cushion, tension
Layer, bottom breaker, lower caldding layer composition, tensile layer is upper covering above upper cushion between each one layer of cushion up and down
Layer, it is lower caldding layer below bottom breaker.
Upper cushion and bottom breaker collectively form cushion.
In the conveyer belt of the present invention, the material of tensile layer is aramid fiber, and structure is for the straight latitude of diameter or directly through knitting latitude canvas or curtain
Cloth.
Preferably, upper lower caldding layer uses flame retardant rubber in conveyer belt.
Preferably, the material of cushion is glass fibre or aramid fiber, and structure is eyed structure.
Beneficial effects of the present invention：
The fire retarding conveying band of the present invention, the physical and mechanical properties of upper lower caldding layer meet 4.5 requirements in MT668-2008.
Inhibiting tape plunger bond strength >=10N/mm.The flame-retarding performance of inhibiting tape meets the requirement of MT668-2008 standards.
The conveyer belt of the present invention uses specific structure, i.e., using kevlar fabric as tensile layer, completed belt tensile strength is high, with
The steel cable core conveying belt ratio band body of equality strength is light, is suitable for underground coal mine use.
