Abstract
The invention provides a shock resistant high wear-resistant conveyor belt made of natural rubber. The conveyor belt is composed of natural rubber, toughened zirconia, butadiene rubber, zinc oxide, stearic acid, activating agent, reinforcing agent, softening agent, anti-ageing agent and aramid short fiber. The preparation method comprises the following steps: adding the natural rubber, toughened zirconia and the butadiene rubber in an internal mixer to pre-press and mix, adding the stearic acid, the activating agent and the anti-aging agent to mix, and then adding the zinc oxide, the reinforcing agent, the softening agent and the aramid short fiber to mix, processing into a section of rubber compound; parking the above rubber compound, and then adding in the internal mixer to continuously mix, and then adding the cross-linking agent, uniformly mixing and then discharging rubber, processing into middle rubber; finally heat cooking and rolling the above final rubber as a rubber plate, gluing and molding the rubber plate and a tensile body belt blank, rolling up and vulcanizing, finishing and checking as a finished product.
Description
Technical field
The present invention relates to a kind of conveying belt, particularly relate to a kind of natural rubber impact resistance high wearing-proof conveyer belt.
Background technology
Conveying belt is the integral part of endless belt conveyor, ancillary engineering facility rubber item, and Leather Belt Conveyance material has continuous and efficient feature.Though be long-distance with short distance, field and indoor, heavy and light-duty, level with bend, tilt with vertical, can use under various different transport condition.Its figure can be seen from mine to harbour, from supermarket to airport.It is physical dispersion and the important means concentrated.Conveyor application universal, reflect the modernization water product in a province, city or area to a certain extent in China, compared with automobile, transportation by railroad, it can improve the gradient, shortens haul distance, reduce construction costs and transportation cost.Along with construction industry high speed development, drive the conveying belt market requirement.
The structure of existing conveying belt comprises: upper caldding layer, lower caldding layer, the limit glue skeleton protective layer being arranged on belt carcass casing ply between upper caldding layer and lower caldding layer and being separately positioned on the two ends of upper caldding layer, belt carcass casing ply and lower caldding layer.The conveying belt of said mechanism is at chemical industry, smelt, casting, when using in the industries such as cement, need the material carrying the large bulk of large discharge, material directly contacts the tectum of conveying belt, the surging force produced in course of conveying is delivered to belt carcass casing ply through tectum, the bonding cohesive strength between the tectum of conveying belt and belt carcass casing ply is caused sharply to decline, conveying belt is easily bubbled layering, tear, the work-ing life of conveying belt is shortened greatly, in use need often to change conveying belt, add the labour intensity of operator, can cause producing in the process changing conveying belt interrupting, directly impact uses production cost and the efficiency of enterprise.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of natural rubber impact resistance high wearing-proof conveyer belt.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
By natural rubber, toughened zirconium oxide, that cis-1,4-polybutadiene rubber adds Banbury mixer precompressed is mixing, adds stearic acid, activator, anti-aging agent carry out mixing; Add zinc oxide again, strengthening agent, tenderizer, aramid fiber short fibre carry out mixing, be processed into one section of rubber unvulcanizate; Then adding Banbury mixer after being parked by above-mentioned rubber unvulcanizate continues mixing, then add linking agent through mixing evenly after binder removal, be processed into middle glue; Finally above finished composition is rolled into film through heat refining, film and tension element made-up belt assembly, through rolling sulfuration, finishing verifies as finished product.
Compared with prior art, the beneficial effect of this product:
(1) to bend oar good in the present invention, and groove forming character is good, shock-resistant, and in use conveying belt is not easy foaming layering, tears, long service life, uses convenient, improves production efficiency.
(2) have that warping strength, shock resistance, sticking power are high, the conveying of custody transfer material, material environment bidirectional protective, high spud angle, transport inclination angle can reach 30 degree usually, delivery conduit can spatially arrangement of curves advantage.
(3) aramid fiber short fibre brute force is extra-high, very not easy fracture, be subject to that bulk mineral aggregate impacts, tearing type is radial at conveying belt working face rubber cover, broadwise is arranged alternately in aramid fiber short fibre not easy fracture inside rubber cover, play the cracking that protection delays working face rubber cover, protection tension element belt carcass is not easily destroyed; Meanwhile, the snappiness of rubber cover, high-tenacity, high tear-resistant performance, protect aramid fiber short fibre more not easy fracture again.
Specific embodiment
Particular content of the present invention is described in detail below in conjunction with specific embodiment.
Embodiment 1:
Its preparation method is: by natural rubber, toughened zirconium oxide, that cis-1,4-polybutadiene rubber adds Banbury mixer precompressed is mixing, adds stearic acid, activator, anti-aging agent carry out mixing; Add zinc oxide again, strengthening agent, tenderizer, aramid fiber short fibre carry out mixing, be processed into one section of rubber unvulcanizate; Then adding Banbury mixer after being parked by above-mentioned rubber unvulcanizate continues mixing, then add linking agent through mixing evenly after binder removal, be processed into middle glue; Finally above finished composition is rolled into film through heat refining, film and tension element made-up belt assembly, through rolling sulfuration, finishing verifies as finished product.
The present invention bends that oar is good, and groove forming character is good, shock-resistant, and in use conveying belt is not easy foaming layering, tears, long service life, uses convenient, improves production efficiency.
Embodiment 2:
Preparation method is the same.
Have that warping strength, shock resistance, sticking power are high, the conveying of custody transfer material, material environment bidirectional protective, high spud angle, transport inclination angle can reach 30 degree usually, delivery conduit can spatially arrangement of curves advantage.
Embodiment 3:
Preparation method is the same.
Aramid fiber short fibre brute force is extra-high, very not easy fracture, be subject to that bulk mineral aggregate impacts, tearing type is radial at conveying belt working face rubber cover, broadwise is arranged alternately in aramid fiber short fibre not easy fracture inside rubber cover, play the cracking that protection delays working face rubber cover, protection tension element belt carcass is not easily destroyed; Meanwhile, the snappiness of rubber cover, high-tenacity, high tear-resistant performance, protect aramid fiber short fibre more not easy fracture again.
