What use under the coal mine at present mainly is unitary-core flame-resistant conveying belt and flame-proof armored rope core conveyer belt.The hardness of unitary-core flame-resistant conveying belt is large, and the belt body compliance is poor, and fatigue life and wear-out life are all shorter, can not be used as the tubulose band.Steel core conveyor belt intensity is high, long service life, and core body becomes the pipe ability strong after respectively spreading up and down the horizontal fabric of one deck, is applicable to long-distance transportation.But rope belt band body weight, energy consumption is large, steel rope easy-to-rust under the wet environment under the coal mine, the joint time is long, requires larger to drive roller diameter.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art provides a kind of colliery with kevlar fabric lamination tubulose fire retarding conveying band, by selection, the core design of framework material, produces and satisfies the load-transfer device novel product that uses under the coal mine.
The technical solution of the utility model is as follows: it is characterized in that comprising upper and lower fire-retardant covering glue layer, limit glue, aramid fiber casing play, retardant adhesive glue-line, described aramid fiber casing play is arranged between the upper and lower fire-retardant covering glue layer, is bonded into an integral body by retardant adhesive glue-line and upper and lower fire-retardant covering glue layer.
