Abstract
The utility model provides a whole core fire resistant conveying belt with a transitional layer, and solves the problems in the prior art that a rubber surface delaminates and blisters. The whole core fire resistant conveying belt adopts the structure that the transitional layer is arranged between a framework material and a cover layer; the framework material adopts a dense entirety formed by dipping a fabric entire belt core in plastic and plasticizing the fabric entire belt core; the transitional layer adopts a fire resistant thermoplastic elastic body; and the cover layer adopts fire resistant antistatic cured rubber composite material. As the transitional layer adopting the thermoplastic elastic body is additionally arranged between the entire belt core and the cover layer, the cover layer is tightly bonded together with the belt core through the transitional layer; and as the cover layer and the transitional layer form entire cover glue, and the thickness of the entire cover glue is 6 mm, which is four times of that in the prior art, the service life of the fire resistant belt is prolonged.
Description
Technical field
The utility model relates to a kind of colliery fire retarding conveying band, relates in particular to a kind of fabric unitary-core flame-resistant conveying belt with cambic horizon.
Background technology
Unitary-core flame-resistant conveying belt is the main tool of transportation coal under the present coal mine, stipulate according to MT914-2008 " colliery fabric unitary-core flame-resistant conveying belt ", unitary-core flame-resistant conveying belt divides two types: a kind of is the plastics unitary-core flame-resistant conveying belts, be called for short the PVC type, it is to soak the plasticizing rear surface by the fabric whole belt core to apply one deck Vinyl chloride resin again and form, its advantage is that technology is simple, cost is low, production efficiency is high, flame retardance is good, shortcoming be easily skid, groove forming character is poor, carry that the inclination angle is little, conveying efficiency is low; Another kind is the rubber face unitary-core flame-resistant conveying belt, be called for short the PVG type, it is to soak the plasticizing rear surface by the fabric whole belt core to cover one deck flame retardant rubber again and form, its advantage is good springiness, easily grooving, carry that the inclination angle is big, conveying efficiency is high, and shortcoming is that the bond properties of rubber and belt carcass is poor, easily delamination, foaming, service life are lacked.
Summary of the invention
In order to overcome the deficiency of existing PVC, PVG unitary-core flame-resistant conveying belt, the utility model provides a kind of unitary-core flame-resistant conveying belt with cambic horizon, it has not only satisfied the requirement of MT914-2008 " colliery fabric unitary-core flame-resistant conveying belt " fully, and the bond strength and the service life of having improved the rubber face unitary-core flame-resistant conveying belt significantly.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be:
A kind of unitary-core flame-resistant conveying belt with cambic horizon is provided, comprises framework material, overplate, it is characterized in that between framework material, overplate, cambic horizon being set; Described framework material is the closely knit integral body after the plasticizing of fabric whole belt core impregnation, and cambic horizon is fire-retardant thermoplastic elastomer, and overplate is the polysulphide rubbers combination material of flame-retardant and anti-static.
Compared with prior art, the utlity model has following beneficial effect is: owing to increased the cambic horizon of thermoplastic elastomer between framework material and overplate, and thermoplastic elastomer and rubber and plastics all have very high bond strength, make that overplate is that polysulphide rubbers combination material is bonded together securely by cambic horizon and framework material, thereby solved delamination, the bubble problem of rubber face of the prior art effectively, prolonged the service life of inhibiting tape; In addition, owing to used thermoplastic elastomer, can take extruder for shaping and dynamic vulcanization technology, from and the purpose that can reach energy savings and enhance productivity.
Description of drawings
Accompanying drawing is a cross-sectional structure scheme drawing of the present utility model.
Among the figure, 1-framework material, 2-cambic horizon, 3-overplate.
The specific embodiment
The utility model example structure as shown in drawings, it comprises framework material 1, cambic horizon 2, overplate 3.Framework material 1 is the closely knit integral body of fabric whole belt core after soaking plasticizing, and whole belt core is by cotton and syntheticfibres (terylene, nylon) Split Down zygonema respectively, is woven into fabric integral structure more than three layers or three layers with parallel then; Cambic horizon 2 is flame-retardant thermoplastic elastomers, 0.5 to 3 millimeter of thickness; Overplate 3 is polysulphide rubbers combination material of flame-retardant and anti-static, 0.5 to 3 millimeter of thickness.
Manufacture craft is at first the fabric whole belt core to be soaked plasticizing, then by two extruders with flame-retardant thermoplastic elastomer with the plasticizing after whole belt core be pasted together, by two extruders rubber cover is sticked on the surface of flame-retardant thermoplastic elastomer more at last.
