- a molded body is formed by embedding a reinforcing layer formed by extending a plurality of steel cords side by side in an unvulcanized rubber member, and this molded body is then added.
- the unvulcanized rubber is vulcanized by applying pressure at a predetermined pressure while heating at a predetermined temperature. Thereby, the rubber product in which the reinforcing layer composed of the steel cord is embedded is completed.
- An object of the present invention is to provide a reinforcing layer for a rubber product that can effectively reduce the energy required for manufacturing and using the rubber product without impairing the reinforcing function of the reinforcing layer.

- a rubber belt reinforcing layer 5 (hereinafter referred to as a reinforcing layer 5) according to the present invention is embedded in the conveyor belt 9 illustrated in FIGS.
- the reinforcing layer 5 functions as a core layer that bears tension when the conveyor belt 9 is stretched between pulleys.
- the conveyor belt 9 includes a reinforcing layer 5 and an upper cover rubber 6 and a lower cover rubber 7 that are arranged with the reinforcing layer 5 sandwiched between them, and these are integrated.
- the reinforcing layer 5 is composed of a large number of steel cords 1.
- a large number of steel cords 1 are arranged side by side in the belt width direction, and are embedded in rubber that extends in the belt longitudinal direction to form the conveyor belt 9.
- each steel cord 1 is covered with a cushion rubber 8, and the steel cord 1 and the cushion rubber 8 are joined by vulcanization adhesion.
- the cushion rubber 8 is a rubber having excellent adhesiveness.
- the cushion rubber 8, the upper cover rubber 6 and the lower cover rubber 7 are integrated by vulcanization adhesion.
- the conveyor belt 9 is configured by appropriately adding other components such as ear rubbers disposed at both ends in the belt width direction.
- the upper cover rubber 6 and the lower cover rubber 7 a rubber composition made of a diene rubber containing at least natural rubber and having good wear resistance with carbon black or the like is used.
- the thicknesses of the upper cover rubber 6 and the lower cover rubber 7 are appropriately determined depending on the performance required for the conveyor belt 9.
- the steel cord 1 is formed by twisting a plurality of steel wires.
- the steel cord 1 is substantially straight without being brazed. That is, the steel cord 1 is not so crimped.
- the structure of the steel cord 1 will be described later. It is preferable that the S-twisted steel cord 1 and the Z-twisted steel cord 1 are alternately arranged side by side.
- the outer diameter D of the steel cord 1 is set to 0.35 mm or more and 6.0 mm or less.
- the strength of the steel cord 1 is, for example, not less than 500 kN and not more than 5000 kN.
- the horizontal pitch P of the steel cord 1 is set to more than 0.35 mm and less than 7.0 mm.
- Cushion rubber 8 is interposed between the adjacent gaps of the side-by-side steel cords 1 so that they are not in contact with each other. Therefore, the gap between the steel cords 1 that are adjacent in a row is more than 0 mm. This gap is preferably less than or equal to the outer diameter D of the steel cord 1, for example, 0.2 mm or more and 1.5 mm.
- the weft thread 4 passes between the steel cords 1 in a side-by-side state so as to sew up and down.
- the weft yarns 4 are arranged at an interval L in the longitudinal direction of the steel cord 1.
- the weft 4 is subjected to RFL dipping in the manufacturing process.
- the weft 4 is immersed in an RFL (resorcin / formalin / latex) treatment liquid and then dried to form a film of the RFL treatment liquid on the surface of the weft 4.
- the steel cords 1 are connected to each other by the weft 4.
- the weft 4 can be provided arbitrarily. Providing the weft 4 makes it difficult for many steel cords 1 to be arranged side by side in the manufacturing process to be disturbed, so that the handleability of the reinforcing layer 5 is remarkably improved and the productivity of the conveyor belt 9 is improved.
- the distance L between the wefts 4 is set to 16 mm or more and 500 mm or less, for example. If the distance L is less than 16 mm, the number of steps for manufacturing the reinforcing layer 5 becomes excessive. On the other hand, when the distance L is more than 500 mm, the effect of preventing the steel cord 1 from being disturbed by the weft 4 becomes too small.
- the positions where the steel cords 1 are sewn up and down are offset between the wefts 4 adjacent to each other with an interval L therebetween. That is, in the steel cord 1 in which one adjacent weft 4 is disposed on the upper side with a gap L, the other adjacent weft 4 is disposed on the lower side of the steel cord 1.
- the weft 4 is not only traversed so as to sew up and down between each steel cord 1, but also as shown in FIG. 5, every two steel cords 1. It can also be crossed so as to sew up and down. Alternatively, the weft thread 4 can be traversed so that three or four steel cords 1 are sewn up and down.
- resin fiber for example, resin fiber is used. Specifically, polyester fiber, nylon (6 nylon, 66 nylon) fiber, rayon fiber, aramid fiber, vinylon fiber, polyurethane fiber or the like is used as the weft 4.
- the weft 4 is formed by knitting a plurality of long fibers and has a fineness of 300 dtex or more and 5000 dtex or less.
- the weft 4 has a smaller diameter than the steel cord 1.
- the steel cord 1 can adopt various structures.
- the configuration code of any one of the codes is adopted.
- the twist multiple of the steel cord 1 is a value T / D indicating the ratio of the twist pitch T of the steel cord 1 to the outer diameter D of the steel cord 1. If the twist multiple is less than 9, the strength of the steel cord 1 becomes insufficient, and if it exceeds 14, sufficient fatigue resistance cannot be ensured.
- a steel cord 1 having a 1 + 6 configuration illustrated in FIG. 6 has an open structure in which six steel wires serving as side wires 3 are twisted on the outer peripheral surface of one steel wire serving as a core wire 2.
- the steel cord 1 having the 3 + 6 configuration illustrated in FIG. 7 has an open structure in which six steel wires serving as the side wires 3 are twisted on the outer peripheral surface of the three steel wires serving as the core wires 2.
- a steel cord 1 having a 1 + 19 configuration illustrated in FIG. 8 includes six steel wires serving as side wires 3 on the outer peripheral surface of one steel wire serving as the core wire 2, and 12 wires serving as side wires 3 disposed on the outer peripheral surface thereof. Steel wires are twisted together to form an open structure.
- a steel cord 1 having a 1 + SeW (19) configuration illustrated in FIG. 9 has six steel wires serving as side wires 3 on the outer circumferential surface of three steel wires serving as the core wire 2, and side wires 3 disposed further on the outer circumferential surface thereof. Twelve steel wires are twisted together.
- the outer diameter of the relatively small diameter steel wire is 60% or more of the outer diameter of the relatively large diameter steel wire. It may be set to 90% or less. Thereby, the permeability of rubber is improved.
- the steel cord 1 has a small diameter of 0.35 mm or more and 6.0 mm or less as compared with the conventional one, so that the rubber product (conveyor belt 9) in which the reinforcing layer 5 is embedded is also included. Along with this, the thickness and weight are reduced. Thereby, when conveying the conveyor belt 9 to a use site, the energy required when operating on a use site can be reduced.
- the vulcanization time of the conveyor belt 9 is shortened by reducing the thickness of the conveyor belt 9 as the reinforcing layer 5 becomes thinner. Therefore, the energy required when manufacturing the conveyor belt 9 can also be reduced. Therefore, by using the reinforcing layer 5 of the present invention, it is possible to effectively reduce the energy required for manufacturing and using a rubber product in which the reinforcing layer 5 is embedded.
- the strength per steel cord 1 decreases.
- the horizontal pitch P of the steel cords 1 is set to be more than 0.35 mm and not more than 7.0 mm, which is much shorter than the conventional one. Therefore, the number density of the steel cords 1 per unit belt width is improved. Therefore, the number of steel cords 1 that can be embedded per unit belt width is increased, and the total strength as the reinforcing layer 5 can be sufficiently obtained, which can be ensured without impairing the reinforcing function.
- the bending rigidity of the conveyor belt 9 is reduced, and energy loss that occurs when traveling around the pulley is reduced.
- the reinforcing layer 5 constituted by the steel cord 1 is embedded in the conveyor belt 9. The reason for this is that when a plurality of reinforcing layers 5 are embedded, when the conveyor belt 9 travels around the pulleys, a compressive force acts on the steel cord 1 constituting the reinforcing layer 5 embedded on the inner peripheral side, and seats. It is because it becomes easy to bend.
- the outer diameter D of the steel cord 1 is set to 0.35 mm or more and 6.0 mm or less, the energy required for manufacturing and using the rubber product in which the reinforcing layer 5 is embedded is ensured while the reinforcing function as the reinforcing layer 5 is secured. This can be further reduced.
- the rubber product in which the reinforcing layer 5 of the present invention is embedded is not limited to the conveyor belt 9, and examples include various rubber products in which the steel cord 1 is embedded as a reinforcing material, such as tires, rubber hoses, marine hoses, and fenders. it can.
- the thickness of the equivalent performance (the total strength of the reinforcing layer is made substantially the same) with one reinforcing layer embedded by changing only the outer diameter and the number of steel cords constituting the reinforcing layer 5.
- the weight of the conveyor belt and the vulcanization time are estimated.
- a specification in which the outer diameter D of the steel cord is 10.4 mm, the side-by-side pitch P is 16 mm, and the number of buried cords is 59 is a conventional example.
- a specification in which the outer diameter D of the steel cord is set to 6.0 mm, the side-by-side pitch P is set to 7.0 mm, and the number of embedded cords is 135 is taken as an example.
- the weight of the conveyor belt of the example can be reduced by about 18% and the vulcanization time can be shortened by about 15% with respect to the conventional example.
