Abstract
The utility model discloses a polyurethane whole core fire resistant conveyer belt. The drawbacks of the thin coverage rubber layer, bad adhesive power, easy loose of rubber layer, not adaptive to large slope transportation place, and other drawbacks of the prior whole core fire resistant belt are solved. Polyurethane upper coverage rubber, polyurethane lower coverage rubber and polyurethane edge rubber are positioned around the belt core. The thickness of the upper coverage rubber and the lower coverage rubber can be adjusted between 1nm and 20nm, the belt core layer is protected well, the service life of the whole core fire resistant conveyer belt is prolonged, and the whole core fire resistant conveyer belt can be widely used in the places which have demands of fire resistant and antistatic.
Description
Affiliated technical field
The utility model relates to the load-transfer device that uses on a kind of conveyer, the whole belt core that relates to a kind of nylon fiber, poly-ester fibres, cotton fiber integral weaving or rather is through a kind of novel unitary-core flame-resistant conveying belt of vacuum-latexed and composite flame-proof polyurethane elastomer.
Background technology
Existing unitary-core flame-resistant conveying belt for radially, is a broadwise with nylon, cotton fiber with nylon, poly-ester fibres, and the warp loom braiding forms whole belt core, and through depilation and dry the processing, the PVC band is made in vacuum impregnation Welvic and high temperature gelling then.With the mixing sizing material of making of general purpose rubber, PVC, vulcanizator and fire retardant,, make PVG type band through the hot press moulding sulfuration again through calendering and PVC band rubberizing moulding.PVC, PVG unitary-core flame-resistant conveying belt be because belt carcass adopts integral weaving and vacuum-latexed, and fire-retardant, antistatic property satisfies coal mine downhole safety production demand, integral weaving belt body anti-pound wear, shock-resistant and tear resistance is good.But PVC type tape surface is for lacking elastomeric polyvinyl chloride layer, and friction coefficient is little, carries the inclination angle to surpass 12 ° of materials and skids at zone face, is difficult to satisfy transportation request; The whole core band rubber cover thickness of PVG type has surpassed 2.0mm; the friction roll Test item that flame retardance requires just be very difficult to by; and the bond strength between rubber cover and the core body descends significantly; the easy delamination of rubber cover in the use, upper and lower rubber cover protective cover are difficult to reach the good protection effect to core body.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of performance more excellent unitary-core flame-resistant conveying belt.
The technical solution of the utility model is as follows, comprises whole belt core, it is characterized in that being provided with around belt carcass rubber cover under rubber cover on the polyurethane, the polyurethane, polyurethane limit glue.
On the described polyurethane under rubber cover, the polyurethane rubber cover, polyurethane limit glue thickness be 1-20mm.
Polyurethane integral core fire retarding conveying band described in the utility model, make full use of existing unitary-core flame-resistant conveying belt anti-pound wear, the advantage of shock-resistant and anti tear, in whole core band impregnation plasticizing, stick on the thick flame resistance polyurethane elastomer of a bed thickness 1-20mm, make the total quality of load-transfer device obtain bigger raising, can satisfy the requirement of various abominable environments for use, compare wear resisting property≤100mm with the similar load-transfer device of prior art
3, be 1/2nd of traditional product, overplate can reach 7-10N/mm with the bond strength of belt carcass interlayer, has solved the delamination of traditional product overplate and has fallen the glue defective, is fit to the load-transfer device of the various fabric widths of intensity 680N/mm to 4000N/mm.Simultaneously in light weight, convenient for installation and maintenance, can cut use, be 2-3 times of existing product service life, fire retardant, antistatic satisfies the coal mine downhole safety demand fully.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1. rubber cover on the polyurethane, 2. belt carcass, 3. rubber cover under the polyurethane, 4. polyurethane limit glue.
The specific embodiment
As shown in drawings, polyurethane integral core fire retarding conveying band described in the utility model, comprise on belt carcass 2, the polyurethane rubber cover 3, polyurethane limit glue 4 under rubber cover 1, the polyurethane, flame resistance polyurethane elastomer is set around belt carcass 2 in the plasticizing of belt carcass impregnation.
Belt carcass 2 is selected for use excellent polyster fibre, nylon fiber, cotton fiber to pool capital in proportion and is twisted thread, be woven into whole belt core, handle through depilation and oven dry, in the thickener that PVC, plasticizer are made, flood, and gel plasticizing at a certain temperature, simultaneously under hot, extrude upper and lower rubber cover of polyurethane and polyurethane limit glue, make the polyurethane integral core fire retarding conveying band through pressing.
Claims (2)
1. a polyurethane integral core fire retarding conveying band comprises whole belt core, it is characterized in that at belt carcass (2) rubber cover (3) under rubber cover on the polyurethane (1), the polyurethane, polyurethane limit glue (4) being set on every side.
2. polyurethane integral core fire retarding conveying band as claimed in claim 1 is characterized in that rubber cover (3) under rubber cover on the described polyurethane (1), the polyurethane, polyurethane limit glue (4) thickness are 1-20mm.
