Problems solved by technology

[0005] The existing elevator belt products mainly use steel mesh and steel wire rope as the skeleton material, and the protective structure for drilling is single, and there are few high-temperature-resistant products for the special working conditions of cement high-temperature powder, because it is difficult to resist high temperature for a long time. The belt body is damaged, the service life is short, and the replacement is frequent

Embodiment 1

[0034] Such as Figure 1~2 As shown, a high temperature and wear-resistant hoist belt includes an upper cover rubber layer 1, an upper canvas layer 2, an upper steel mesh layer 4, a middle skeleton layer 5, a lower steel mesh layer 6, a lower canvas layer 7 and a lower cover rubber layer Layer 8: The high temperature and wear-resistant hoist belt is sequentially provided with an upper cover rubber layer 1, an upper canvas layer 2, an upper steel mesh layer 4, an intermediate skeleton layer 5, a lower steel mesh layer 6, and a lower canvas layer 7 and the lower cover glue layer 8.

[0035] It also includes an adhesive rubber layer 3; the upper and lower surfaces of the upper canvas layer 2 and the lower canvas layer 7 are compounded with a layer of adhesive rubber layer 3.

Embodiment 2

[0037] (1) Preparation of the upper cover rubber layer 1 and the lower cover rubber layer 8: the formula ratio is as follows in parts by weight, 100 parts of ethylene propylene rubber, 30 parts of carbon black N234, 15 parts of carbon black N220, and 2.5 parts of vulcanizing agent DCP Zinc oxide is 8 parts, stearic acid is 2 parts, accelerator TAIC is 2 parts, accelerator CZ is 1 part, antioxidant 4020 is 2 parts, antioxidant MB is 2 parts, paraffin oil is 10 parts, carbon 5 Petroleum resin is 3 parts, polytetrafluoroethylene is 25 parts, and basalt fiber is 2 parts. The above raw materials were kneaded at 130°C for 6 minutes, and then extruded at 50°C after standing for 8 hours to prepare a 10mm upper cover rubber layer 1 and a 5mm lower cover rubber layer 8.

[0038] (2) Preparation of the upper canvas layer 2 and the lower canvas layer 7: a high-temperature-resistant canvas woven with basalt fibers in the warp direction and polyester fibers in the weft direction;

Abstract

The invention relates to a high-temperature-resistant wear-resistant lifter belt and a preparation method thereof and belongs to the technical field of rubber products. The high-temperature-resistantwear-resistant lifter belt is successively provided with an upper cover rubber layer, an upper canvas layer, an upper steel net layer, a middle framework layer, a lower steel net layer, a lower canvaslayer and a lower cover rubber layer from top to bottom. The high-temperature-resistant wear-resistant lifter belt also comprises adhesive rubber layers which are compounded to the upper and lower surfaces of the upper and lower canvas layers. The high-temperature-resistant wear-resistant lifter belt product is prepared by the following steps: mixing, calendering, extruding, forming and vulcanizing a conventional conveyor belt. In a continuous high-temperature working condition, the belt body can keep high strength, and does not stretch after long-term use; the steel nets are paved above andbelow the framework, so that the belt body is effectively prevented from being damaged by a hopper after the lifter belt is perforated and the hopper is mounted; the high-temperature-resistant canvaslayers play roles of isolating heat and buffering, so that the framework layer of the belt body is further protected, and bolts are favorably fastened when the hopper is mounted; the high-temperature-resistant canvas layers adopt a rubberizing formula of pure ethylene propylene rubber, so that the high-temperature-resistant wear-resistant lifter belt has a good temperature-resistant characteristic. The canvas layers and the cover rubber are adhered together well at continuous high temperatures.

Description

technical field [0001] The invention relates to a high-temperature-resistant and wear-resistant hoist belt and a preparation method thereof, in particular to a conveyor belt suitable for bucket elevator conveying systems in domestic and foreign cement and steel industries, and belongs to the technical field of rubber products. Background technique [0002] The bucket elevator is used for conveying powder, granular and small block materials when vertically inclined. The bucket elevator has a small cross-sectional dimension, a compact conveying system, a large lifting height, and good sealing. However, the hopper and traction components of the bucket elevator are easily damaged. [0003] Bucket elevator conveyor belts are widely used in the industrial transportation fields such as steel and cement at home and abroad, especially in the cement industry, which has a huge demand. The bucket elevator is used to transport cement, which has a large volume and less powder flying, bu...
