Novel wear-resistant and heat-resistant rubber conveyor belt

Abstract

The invention discloses a novel wear-resistant and heat-resistant rubber conveyor belt which comprises a framework, a covering layer and an adhesive layer, and consists of styrene-butadiene rubber, highly wear-resistant carbon block, ethylene propylene diene monomer, zinc oxide, stearic acid, terpene resin, calcium carbonate and an accelerant. A preparation method of the conveyor belt comprises the following steps: adding the styrene-butadiene rubber into an internal mixer, and adding the highly wear-resistant carbon block, the ethylene propylene diene monomer, the stearic acid and the terpene resin to perform internal mixing; adding zinc oxide, calcium carbonate and the accelerant to perform internal mixing, thereby obtaining a rubber compound; performing reprocessing on the rubber compound on a mixing mill; and putting the rubber compound subjected to reprocessing into a calender to perform cloth sticking operation, thereby obtaining a product for the covering layer of the heat-resistant conveyor belt. The novel wear-resistant and heat-resistant rubber conveyor belt disclosed by the invention can meet requirements on oil resistance and heat resistance, can meet conveyance of special materials in special environments, and broadens the application range of the conveyor belt.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, and in particular relates to a novel wear-resistant and heat-resistant rubber conveyor belt. Background technique [0002] Conveyor belt, also called conveyor belt, is a composite product of rubber, fiber and metal, or a composite product of plastic and fabric, which is used to carry and transport materials in belt conveying. Conveyor belts are mainly used for solid material transportation in mining, metallurgy, steel, coal, hydropower, building materials, chemical, food and other enterprises. The conveyor belt is generally composed of a skeleton, a covering layer and an adhesive layer. The skeleton is mainly used for guiding, loading and extending the conveyor belt; the covering layer is mainly used to protect the skeleton, protect the conveyed material and increase the friction coefficient; the adhesive layer is mainly used In order to have good bonding strength between the skeleton and...

AI Technical Summary

Problems solved by technology

[0004] At present, conveyor belts with various special properties have been widely used, but in many kinds of conveyor belts with special properties, the requirements for heat-resistant conveyor belts and wear-resistant conveyor belts cannot be shared, that is, conveyor belts with wear-resistant properties Not heat resistant, whereas belts that are heat resistant are not wear resistant

The heat-resistant conveyor belt makes the conveyor belt have good heat resistance, and avoids early aging phenomena such as hardening and cracking of the conveyor belt during high-temperature and high-heat use. In the process of use, a large amount of wear and tear will inevitably occur phenomenon, which in turn affects the service life of the conveyor belt; wear-resistant conveyor belts are usually used to avoid early wear and tear of the conveyor belt during use, resulting in a shortened service life of the conveyor belt

However, in actual use, high temperature and high heat often exist. If it is used under high temperature and high heat for a long time, there will inevitably be early aging phenomena such as hardening and cracking due to poor heat resistance of the conveyor belt, which will affect the conveying belt. With service life

Therefore, it can be seen that there is an urgent need for a conveyor belt with good wear resistance and heat resistance in the market, but in the national standard, the general conveyor belt standard makes requirements for wear resistance, but does not specify heat resistance. Requirements are made, or in the heat-resistant conveyor belt standard, only heat-resistant performance is required, but no wear-resistant performance is required. It can be seen that the conveyor belt with both performances still lacks technical support. Therefore, both Wear-resistant and heat-resistant conveyor belts have become the focus of research
