Abstract
The invention discloses a flame-retardant belt core for conveying belts. The flame-retardant belt core comprises an upper flame-retardant layer, a lower flame-retardant layer and a core layer between the upper flame-retardant layer and the lower flame-retardant layer. The upper flame-retardant layer and the lower flame-retardant layer are flame-retardant glass fiber cloth layers, and the core layer is made of warps and wefts by interweaving. The warps and the wefts are structurally identical, and each warp is made by combining and twisting at least three nylon fibers, at least three cotton fibers and at least three jute fibers. The flame-retardant belt core for the conveying belts has excellent flame-retardant performance and is capable of fully meeting high requirements of the conveying belts.
Description
Technical field
The present invention relates to load-transfer device technical field, particularly relate to a kind of fire-retardant belt carcass for load-transfer device.
Background technology
Load-transfer device is conveyer belt again, is the rubber for playing carrying and the effect of transport material in belt conveyor and fiber, metal composite goods, or the goods of plastics and fabric compound.Load-transfer device is widely used in the occasion that in the industries such as cement, coking, metallurgy, chemical industry, iron and steel, fed distance is shorter, operational throughput is less.Load-transfer device generally comprises skeleton (belt carcass) and overplate, and knitting skeleton is a kind of skeleton conventional at present, but the flame retardance of existing this skeleton is bad.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of fire-retardant belt carcass for load-transfer device, has good flame retardance, fully meets the high request of load-transfer device.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of fire-retardant belt carcass for load-transfer device, comprise: upper flame-retardant layer, lower flame-retardant layer and the sandwich layer be arranged between described upper flame-retardant layer, lower flame-retardant layer, described upper flame-retardant layer is combustion-proof glass fiber layer of cloth, described lower flame-retardant layer is combustion-proof glass fiber layer of cloth, described sandwich layer adopts warp thread and weft yarns to form, described warp thread is identical with weft yarn structure, and described warp thread merges twisting by least three nylon fibers, at least three cotton fibers and at least three flaxen fibers and forms.
In a preferred embodiment of the present invention, the thickness of described upper flame-retardant layer is 1 ~ 5 millimeter, and the thickness of described lower flame-retardant layer is 1 ~ 5 millimeter.
In a preferred embodiment of the present invention, the thickness of described sandwich layer is greater than the thickness of flame-retardant layer, and the thickness of described sandwich layer is greater than the thickness of lower flame-retardant layer.
In a preferred embodiment of the present invention, the fineness of described nylon fiber is 70D.
The invention has the beneficial effects as follows: the present invention is used for the fire-retardant belt carcass of load-transfer device, has good flame retardance, fully meets the high request of load-transfer device.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
