Embodiment
Below, with reference to Fig. 1, the related flat rubber belting of a mode of execution of the present utility model is described.As shown in Figure 1, the flat rubber belting 10 of present embodiment is using PA membrane 1 as core body, and set rubber layer 3 on two surfaces of core body, be formed with concavo-convex (not shown) of cloth pattern on the surface of at least single face of described rubber layer 3, wherein, be equipped with polyamide canvas 2 between described PA membrane 1 and rubber layer 3, being provided with phenolic resin between described rubber layer 3 and polyamide canvas 2 is sticker layer 4, and being provided with resorcinol between described PA membrane 1 and polyamide canvas 2 is sticker layer 5.
The core body of flat rubber belting 10 of the present utility model that is described PA membrane 1 consist of a kind of nylon of polyamide synthetic resin, for example, the mixture, nylon 66 of enumerating nylon 6, nylon 66, nylon 6/66 copolymerization, nylon 6 and nylon 6/66 copolymerization and the mixture of nylon 6/66 copolymerization etc.
It should be noted that, suitably add the affixs such as heat-resisting stabilizing agent, anti-live agent, plasticizer, impact improver, intensifier, processing aids in the above-mentioned material that also can use to PA membrane 1.
As shown in Figure 1, being respectively equipped with resorcinol on two surfaces of described PA membrane 1 is sticker layer 5, and is equipped with polyamide canvas 2.
This resorcinol is that sticker layer 5 is bonding securely by PA membrane 1 and polyamide canvas 2.Resorcinol is that the main component of tackiness agent is resorcinol.
As described polyamide canvas 2, do not limit especially, enumerate such as the mixture of nylon 6, nylon 66, nylon 6/66 copolymerization, nylon 6 and nylon 6/66 copolymerization etc.
As shown in Figure 1, described rubber layer 3 is positioned at the outermost surface on two surfaces of flat rubber belting 1, as the carrying of load, via the transmission of the drive after pulley and main shaft.Surface at least single face of this rubber layer 3 is formed with the concavo-convex of cloth pattern 31 described later.
The rubber used as this rubber layer 3 is restriction especially not, for example, by the rubber composition that has used natural rubber, chloroprene rubber, nitrile butadiene rubber, acrylic rubber, urethane rubber, ethylene propylene rubber, styrene butadiene rubbers, butyl rubber, chlorosulfonated polyethylene rubber, silicone rubber etc., formed.
As shown in Figure 1, being provided with phenolic resin between described rubber layer 3 and described polyamide canvas 2 is sticker layer 4.
This phenolic resin is that sticker layer 4 is bonding securely with described polyamide canvas 2 by described rubber layer 3.
In addition, in flat rubber belting 10 of the present utility model, thickness does not limit especially, but the thickness of preferred polyamide film 1 is 0.2～2.0mm, and preferably the thickness of one-sided rubber layer 3 is 0.1～3.0mm.
As described above, using PA membrane 1 as core body and in two surfaces of this core body set rubber layer 3 and set the flat rubber belting 10 of polyamide canvas 2 between described PA membrane 1 and rubber layer 3, being provided with phenolic resin between described rubber layer 3 and polyamide canvas 2 is sticker layer 4, being provided with resorcinol between described PA membrane 1 and polyamide canvas 2 is sticker layer 5, each layer be by bonding securely thus, thereby can prevent that each layer easily peeled off in the using process of band.
The concavo-convex rubber at rubber layer 3 of the cloth pattern 31 on the surface of the rubber layer 3 shown in Fig. 1 adds in the sulphur operation and forms.
In the situation that described cloth pattern 31 is located to the surface of rubber layer 3, described rubber layer 3 is not adding under the state of sulphur, surface bears cloth pattern raw material at this rubber layer 3, then pressurize sulphur and described cloth pattern raw material are suppressed at rubber covering, keep this state to continue to add sulphur and peel off described cloth pattern raw material adding after sulphur finishes, cloth pattern concavo-convex can be located on the surface of rubber layer 3 thus.
Above-mentioned rubber material add the sulphur operation, if be needed on the cloth pattern raw material on the surface of described rubber layer 3 form concavo-convex, weave cotton cloth or nonwovens all can, but be preferably any in the TAFFETA cloth of the flat fabric of thick eye or thin eye.
The eye (concavo-convex formation interval) of the cloth of the pattern that uses the flat fabric of thick eye and form in the cloth pattern 31 on the surface of described rubber layer 3 is thick and friction factor is high.Therefore, the pattern of at least transmission of power face of described rubber layer 3 is used the pattern of thick eye to get final product.
In addition, in the cloth pattern 31 on the surface of described rubber layer 3, use the TAFFETA cloth of thin eye and the eye of the cloth of the pattern that forms is thin and friction factor is low.Therefore, can in the carrying face such without the height of friction factor, use.
It should be noted that, in the situation that described cloth pattern 31 is located at two surfaces of described rubber layer 3, this cloth pattern can be two surfaces all identical, also can be that two surfaces are different.
Adjusted as any the concavo-convex difference of height of 31 pairs of cloth eyes of described cloth pattern in the TAFFETA cloth of the flat fabric of above-mentioned thick eye or thin eye, can be adjusted thus the friction factor on described rubber layer 3 surfaces.
The concavo-convex difference of height of above-mentioned cloth pattern 31 is preferably 0.01～0.10mm.
As shown in Figure 2, above-mentioned flat rubber belting 10, by its both ends of the surface being docked mutually and to carry out joint by sticker layer bonding, can form ring-type thus.
As shown in Figure 2, the both ends of the surface of flat rubber belting 10 are processed into inclined plane shape.This processing does not limit especially, and grinding to form slope (b/a) is that 1/20～1/60 left and right gets final product.
The rubber layer 3,3 of flat rubber belting 10 is each other by isocyanate-based sticker layer 6 and bonded, and in addition, it is sticker layer 7 and bonded by resorcinol each other that the PA membrane 1,1 of flat rubber belting 10 reaches polyamide canvas 2,2 each other.
As described above, if the both ends of the surface that make flat rubber belting 10 are sticker layer 7 and be bonded into mutual the docking by described isocyanate-based sticker layer 6 and resorcinol, become the flat rubber belting that is bonded into ring-type.In this case, connector portions is sticker layer 7 and by bonding securely by isocyanate-based sticker layer 6 and resorcinol.
