Embodiment 1
[0022] A kind of aramid cord rubber conveyor belt, such as figure 1 , including an upper cover layer 1, an upper adhesive layer 2, an intermediate layer 3, a lower adhesive layer 4 and a lower cover layer 5, the intermediate layer 3 is arranged in the middle of the conveyor belt, and the upper adhesive layer 2 is located between the intermediate layer 3 and the upper Between the covering layers 1, the lower adhesive layer 4 is located between the intermediate layer 3 and the lower covering layer 5;
[0023] The middle layer 3 includes core rubber 31 and aramid rope 32. The core rubber 31 wraps the aramid rope 32, and the aramid rope 32 is evenly arranged in the middle layer 3. Compared with the ordinary fabric whole core conveyor belt, the conveyor belt has improved the strength of
[0024] Aramid rope 32 is composed of 1 set of rope core and 6 sets of rope strands, the arrangement is 1+6, the way of jointing is left or right, the twist is 50±5 turns / m, the rope core is cotto...

The invention particularly relates to an aramid fiber rope core conveying belt which comprises an upper covering layer, an upper bonding layer, a middle layer, a lower bonding layer and a lower covering layer. The middle layer comprises core glue and an aramid fiber rope, the aramid fiber rope is wrapped by the core glue, the aramid fiber rope is evenly distributed on the middle layer, the aramidfiber rope is composed of one group of rope cores and six groups of strands, the arrangement mode of the aramid fiber rope is 1+6, the stranding mode is leftward or rightward, the twist is 50+ / -5 turns / m, the rope cores are cotton yarns, and the strands are the plied yarns of the aramid fibers and the cotton yarns. A fiber cloth is arranged in the upper bonding layer and is formed by weaving polyester yarns through warps and wefts, and a non-woven fabric is arranged on the upper covering layer. According to the conveying belt, the aramid fiber rope formed by stranding the cotton yarns and thearamid fibers is used as a framework material, so that the strength of the fabric whole-core conveying belt is improved, and separation of the aramid fiber rope and the core glue is avoided. Fiber canvas is arranged in the upper bonding layer of the conveying belt, so that the transverse tensile strength of the conveying belt is increased, and the transverse tearing phenomenon is avoided.
Description
technical field [0001] The invention belongs to the field of conveyor belts, in particular to an aramid cord conveyor belt. Background technique [0002] At present, there are mainly two types of flame-retardant conveyor belts used in underground coal mines in my country: one is a flame-retardant steel cord conveyor belt for coal mines, and the other is a fabric whole-core flame-retardant conveyor belt for coal mines. Flame-retardant steel cord conveyor belt, with steel cord as the longitudinal skeleton material, has poor chemical corrosion resistance, heavy weight, high energy consumption, and is easy to tear in the longitudinal direction. The fabric whole core flame retardant conveyor belt mainly adopts the integral belt core woven with polyester and cotton yarn as the warp and weft. Compared with the steel cord conveyor belt, it is light in weight and good in tear resistance, but weak in strength. [0003] Aramid fiber is the strongest among the currently used organic fi...
