A kind of high temperature resistant steel wire rope core hoisting belt

Abstract

The invention provides a high-temperature-resistant steel wire rope core lifting belt, which comprises an upper anti-tearing layer, a lower anti-tearing layer, a core rubber layer and a plurality of longitudinal steel wire rope cores, wherein the core rubber layer is positioned between the upper anti-tearing layer and the lower anti-tearing layer; a plurality of the longitudinal steel wire rope cores are arranged uniformly and are wrapped in the core rubber layer; an upper heat-insulating layer is formed above the upper anti-tearing layer; a lower heat-insulating layer is formed below the lower anti-tearing layer; ethylene-propylene-diene monomer is adopted between the upper heat-insulating layer and the lower heat-insulating layer; and asbestos fibers, aramid short fibers and a bonding agent are added into the ethylene-propylene-diene monomer. Compared with the prior art, the high-temperature-resistant steel wire rope core lifting belt has the advantages that aging and cracking of the rubber layer can be effectively prevented, the core rubber layer and the steel wire rope core are protected from aging and breaking away, the service life of a conveying belt is prolonged, the damaging rate of the conveying belt is effectively reduced, the production cost is lowered, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a hoisting belt, in particular to a hoisting belt with a high temperature resistant steel cord core. Background technique [0002] Elevating belts are widely used in close-distance vertical material transportation such as building materials, mines, ports, steel, etc. It is convenient and fast, and has high production efficiency. [0003] At present, the general high-temperature-resistant lifting belt has poor heat resistance and short service life. The main reason is that during use, the heat of high-temperature materials is easily transferred to the inside of the belt, which causes the cover rubber of the belt to age easily and crack. The adhesive layer of the belt and the skeleton rope core are detached, resulting in a shortened service life of the belt. [0004] Therefore, it is necessary to make further improvements to the prior art. Contents of the invention [0005] The object of the present invention is to provide a ...
