Definitions
- the invention relates to a composite laminate, in particular material to be conveyed, consisting of a carrier which essentially determines a mechanical stability of the composite laminate and at least one cover plate made of rubber, thermoplastic elastomer and / or plastics which have a high resistance to mechanical damage Has the shape of notches, cuts or the like.
- a particularly important example of a composite laminate according to the invention is a conveyor belt.
- the conveyor belt as an integral part of belt conveyor systems has two main tasks. One is to transmit a belt tensile force in order to build up sufficient normal forces in the belt between the drive drums that are suitable for transmitting the drive force by means of the friction on the belt. The tensile force for overcoming the resistance to movement is absorbed by the mechanical reinforcement arrangements located in the belt.
- the conveyor belt is also intended to transport material to be conveyed. The material to be conveyed is regularly thrown onto the conveyor belt from a height of up to 10 m. Since the material to be conveyed also has sharp-edged rock or the like. may be, the conveyor belt must be designed so that the impact of the material to be conveyed on the conveyor belt does not damage the belt.
- the conveyor belt is provided with a cover plate, which in particular has the task of protecting the mechanical reinforcement arrangement in the tension member layer serving as the carrier from damage, since such damage impair or cancel the functionality of the belt.
- Steel cord arrangements or arrangements of several fabric layers are common for the reinforcement arrangement.
- the cover plate of a conveyor belt suffers a graining of the upper layer due to the constant sprinkling of the bulk material particles, possibly with the formation of smaller notches.
- the notches or scars can be the starting point for incisions or hairline cracks, which are dependent on the operating conditions (belt speed, trough of the conveyor belt, distance of the drive rollers), the goods to be conveyed and the belt properties due to the constantly changing tension states and propagate concentrations at the crack tip. This can lead to punctures up to the tension member layer, which puts the functionality of the conveyor belt in question. For this reason, a conveyor belt that has been exposed to the bulk material for a long time is renewed in practice if the surface of the cover plate has numerous scars and notches due to the continuous impacts of the bulk material.
- a known measure for increasing the service life consists in increasing the cover plate thickness. This increases the energy required for the breakdown. However, it cannot be prevented that notches and cuts lead to breakdown even through the greater cover plate thickness. The effect achieved with the increased cost of materials is therefore limited.
- Transverse reinforcement consists in absorbing high energy inputs of the falling material by itself absorbing forces, distributing the stresses and thus preventing direct strikethrough on the tension member layer. Above all, it prevents longitudinal cuts that can lead to the unraveling of steel cables. However, the risk of notches and incisions cannot be eliminated.
- REPLACEMENT LEAF It is also known to introduce fibers into the cover plate material in order to increase the service life of belt cover plates.
- the fiber distribution must be unoriented so that there are no different properties of the cover plate in the longitudinal and transverse directions.
- the usual processing (calendering) of the cover plate results in a preferred direction of the fibers, which does not make it possible to build up a closed fiber network.
- the introduction of fibers into the cover plate is therefore only of limited use.
- Another example of a composite laminate mentioned at the outset is a roller with a cover layer applied to a metallic core which is subjected to similar loads to the cover layer of a conveyor belt due to granular and sharp-edged rolling stock.
- a composite shoe body designed as a conveyor belt of the type mentioned is known from DE-OS 17 50 410.
- several tension-absorbing layers are provided, the cover plates closing the tension-absorbing layers from the outside being constructed in one layer.
- EP 0 431 907 A2 discloses a roller coated with rubber, on the metal core of which two rubber layers are applied, the two rubber layers being formed from essentially the same base material and the outer rubber layer merely adding an additive, for example to increase the abrasion resistance in the form of a zinc salt.
- DE 33 42 560 A1 discloses a multi-layer roof sealing membrane in which an EPDM rubber which is advantageous per se is provided with a glass fiber reinforcement, but is covered on the outside by a SEBS rubber layer which favors the usual laying of the roof sealing membrane.
- the multilayer structure therefore results from the usual laying technology for roof sealing sheets and is not to be increased.
- This has an outer wear layer with a Shore A hardness of 45 to 75, an underlying soft rubber layer with a Shore A hardness of 45 to 55, a support layer and a fourth layer of soft rubber with a Shore A hardness of 45 to 75 75.
- the support layer consists of a steel layer, a fabric layer or a hard rubber layer with a Shore D hardness of approximately 70 to 80.
- the corresponding coating should have a high resistance to chemically aggressive materials which are used in flue gas desulphurization plants enable.
- the problem on which the invention is based is to improve the cover plate of a composite laminate of the type mentioned at the outset in such a way that longer service lives against mechanical damage in the form of notches, cuts or the like are possible.
- the composite laminate of the type mentioned at the outset is characterized according to the invention in that the cover plate is formed from at least two layers with different properties which are connected to one another and form a clear phase boundary between them, which prevents crack propagation, in that the outer first layer of the cover plate has a hardness which is at least 10% higher than that of a second layer of the cover plate adjacent to the inside of the first cover layer, the hardness of the first layer being between 50 and 80 and the second layer between 35 and 60 Shore A, and wherein the second layer adjoining the first layer is larger than
- the cover plate of the composite laminated body according to the invention which has the protective function, is constructed in several layers, the formation of the multiple layers with the different hardness and elasticity properties creating a clear phase boundary in the composite. As a result, if a crack is formed in the outer layer of the cover plate, the propagation of the crack at the phase boundary is stopped or at least inhibited. With the cover plate having the same thickness, the multilayer structure with the layers designed according to the invention can therefore achieve a significantly improved protective function with the cover plate.
- the cover plate consists of three layers with two distinct phase boundaries.
- the material of the cover plate is preferably a rubber material based on natural and / or synthetic rubbers.
- the first, outer layer of the cover plate preferably has at least 30% of the thickness of the cover plate if the total thickness of the cover plate is, for example, 15 to 20 mm. If the total thickness is significantly smaller, the outermost layer should have a larger relative thickness up to 50%.
- the first layer is expediently carried out with the greatest hardness and serves as an "armored layer".
- the second layer is preferably more elastic than the first layer in order to be elastic, that is, energy introduced via a crack tip or a notch. to be able to record without material destruction.
- the hardness of the first layer should preferably be 65 to 72 Shore A and the hardness of the second layer should preferably be 50 and
- the first and second layers should have a strength of greater than 20 MPa and preferably greater than 25 MPa and an elongation of greater than 400%, preferably greater than 500%.
- An essential parameter for the first layer is a high abrasion resistance.
- the abrasion - measured according to DIN - should be less than 120 mm 3 , preferably less than 100 mm 3 '.
- the elasticity essential for the second layer should preferably be greater than 60%.
- the initiation and propagation of cracks in the cover plate can be reduced in that at least the first layer with active filler, e.g. Carbon black or silica.
- active filler e.g. Carbon black or silica.
- the first layer is preferably formed with a low-sulfur or sulfur-free crosslinked system.
- the differences between the first and the second layer which cause the phase boundary can also include networking with different systems.
- An inner third layer is preferably present, which adjoins the second layer on the inside and has a hardness of 55 to 70 Shore A, preferably 60 to 65 Shore A, which lies between the hardnesses of the first and the second layer.
- FIG. 1 shows a section through a steel cable conveyor belt
- Figure 2 shows a section through a multi-layer rubber conveyor belt
- FIG. 3 shows a section through a cover plate structure with three layers
- Figure 4 shows a section through a roller structure.
- a steel cable belt consists of an outer, i.e. support-side cover plate 1, a tension member layer 2 and a cover plate 3 on the running side.
- the support layer 3 has, as a mechanical reinforcement arrangement, twisted steel cables 4 which are embedded in a rubber material forming the tension support layer 2.
- Cross reinforcements 5, 6 can be introduced between the tension member layer 2 and the cover plates 1, 3.
- FIG. 2 shows a tension member layer 2 ', the mechanical reinforcement arrangement of which consists of three fabric layers 7. Between the fabric layers there are binding layers 8 made of a rubber material based on natural or synthetic rubber. The connection to the cover plates 1, 3 takes place by means of adhesive layers 9 applied to the respectively adjacent fabric layers 7.
- FIG. 3 illustrates that the cover plates 1 according to the invention consist of several layers.
- an outer first layer 10 which functions as an armor layer, is followed by a highly elastic second layer 11 and a third
- SPARE BLADE Layer 12 which can optionally be provided with a transverse arming as a protective layer.
- All three layers 10, 11, 12 are formed from rubber materials or thermoplastic elastomers.
- the first layer 10 has the greatest hardness, the second layer 11 the lowest hardness, however the highest elasticity and the third layer 12 an average hardness.
- FIG. 4 shows a roller, consisting of a metal core as a support 2 ′′, on which a third layer 12 ′, a second layer 11 ′ and a first, outer layer 10 'are applied, which have the same features as the layers 10, 11, 12 of the conveyor belts described above.
