The first warp yarns, the second warp yarns and the weft yarns are all made of nylon 66 fibers, and are subjected to primary twisting and secondary twisting to form ropes of rope-shaped structures.
The diameter of the first warp is 3-4mm, and the diameter of the second warp is 1-1.5 mm; the diameter of the weft yarn is 1-1.5 mm.
Selection of materials: compared with the performance difference of chinlon and polyester fiber, especially the polyester fiber is damaged by amine additives in rubber at high temperature, so that the strength is reduced, and the service life is influenced. This scheme has adopted nylon 66 fibre as the substrate.
The mould canvas is produced by processing nylon 66 industrial yarns through the processes of stranding, twisting, weaving, dipping a release agent, heat setting and the like, and can be used for pressing herringbone patterns.
The application of the mould canvas for pressing herringbone patterns on the surface of the conveyer belt is to use the mould canvas for pressing the herringbone patterns on the surface of the conveyer belt.
The method comprises the following specific steps:
(1) preparing warp and weft yarns:
first warp yarn A: as main warp yarns for forming the positive and negative concavo-convex effect: firstly twisting 940dtex nylon 66 industrial yarns with single strand into a primary twisted wire with 180 twists/m and the twisting direction being S, then twisting 12 strands of nylon 66 industrial yarns by 120 twists/m through plying, twisting in Z direction, then plying and twisting the 3 strands of twisted yarns, twisting with 120 twists/m and S direction, and plying: 940dtex X12X 3, 3-4mm diameter thread;
second warp yarn B: as a matrix for forming the mould canvas, nylon 66 industrial yarns are adopted, single ply 940dtex nylon 66 industrial yarns are subjected to primary twisting of 120 twists/m, Z-direction twisting is adopted, then the 4 ply twisted yarns are subjected to plying and compound twisting, the twist degree is 120 twists/m, S-direction twisting is carried out, and plying is carried out: 940dtex X1X4, 1-1.5mm diameter thread;
weft yarn C: firstly twisting single-stranded 940dtex nylon 66 industrial yarns by 120 twists/m, twisting by S, then plying and twisting the 4 strands of twisted yarns again, twisting with the twist of 120 twists/m and Z into twisted yarns, twisting the 3 strands of twisted yarns in the Z direction by 120 twists/m, and plying into 940dtex X1X 4X 3 threads with the diameter of 1-1.5 mm;
(2) weaving: adopting a double-beam let-off system, wherein a first warp yarn A is fed by adopting a bobbin creel, and a second warp yarn B is fed by adopting the bobbin creel or a beam; during weaving, the width of the grey cloth is ensured to be more than 5% of the required width;
(3) dipping a release agent: before the drum vulcanizer, a water bath is arranged for impregnating the aqueous release agent, and then the aqueous release agent enters a vulcanizing roller of the drum vulcanizer, the steel belt is dried without pressurization by using a heating roller of the drum vulcanizer, the heating temperature is controlled between 150 ℃ and 175 ℃, the running speed of the drum vulcanizer is suitable for drying the mould canvas, and meanwhile, the traction tension in the vulcanizing process is required to be low, and the tension per meter is required to be less than 100 kilograms. Or a vulcanized flat plate can be used as a heating and drying part, after a water bath is arranged for dipping a water-based release agent, the canvas of the mold is introduced into the middle of the flat plate, after the mold is closed, a gap of 20 cm is left between the flat plates for removing water vapor, and the temperature and the time are subject to canvas drying; if the demolding effect is poor, the process of impregnating the demolding agent can be repeated for many times;
(4) and (3) vulcanization: the rubber can be coiled together with a belt blank of the conveying belt as a cloth liner in the forming process of the conveying belt, or can be synchronously fed into a drum vulcanizer or a flat vulcanizer together with the belt blank of the conveying belt in the vulcanizing process, the vulcanizing pressure is controlled to be 1-2MPa, the rubber is prevented from penetrating through canvas of a mold to cause difficulty in demolding, and the rubber is also prevented from being incapable of filling in woven pattern gaps of the mold cloth and effectively forming patterns; when the flat plate is vulcanized, the gap between the upper flat plate and the lower flat plate is 8-10mm, the vulcanization temperature is 150 ℃ and 170 ℃, and the opening tension is 50-80 kg during drying;
(5) demolding: after the conveyer belt is vulcanized, the conveyer belt is properly cooled, and when the temperature of the belt body is reduced to be below 60 ℃, the conveyer belt is separated from the mould canvas, thus obtaining the conveyer belt with the herringbone patterns pressed on the surface.
The invention has the beneficial effects that: the invention uses canvas as a mould, the canvas of the mould is stretched on the surface of the conveyer belt in the vulcanization process, the canvas of the mould is separated from the surface of the conveyer belt after vulcanization, and the canvas of the mould forms a complex organization structure with the herringbone twill of woven fabrics as the main part, thereby forming the surface with obvious concave-convex effect and obviously increasing the friction force on the surface of the conveyer belt.
