Problems solved by technology

[0002] At present, the heat-resistant conveyor belt used to transport high-temperature parts on the iron and steel smelting and casting production line in China has poor heat resistance and short service life, and when the conveyor belt is transferring high-temperature parts, the parts are prone to slip on the conveyor belt. Messy and disorderly, it is easy to cause the danger of scalding, which is not conducive to the production of the next process
The main reason is that during use, the heat of the high-temperature material is easily and quickly transferred to the inside of the belt, which causes the cover rubber of the belt to age and crack, and the rubber layer and the core layer of the belt are separated, resulting in a shortened service life of the belt.

Abstract

The invention provides heat-proof magnetic conveyor belt cover rubber. The cover rubber comprises the following components in parts by weight: 100 parts of ethylene propylene diene monomer rubber, 2-5 parts of anti-aging agent, 5-10 parts of zinc oxide, 2-8 parts of magnesium oxide, 1-3 parts of stearic acid, 25-50 parts of carbon black, 4-6 parts of dicumyl peroxide, 30-50 parts of asbestos fiber, 150-300 parts of magnetic powder, and 5-20 parts of paraffin oil. In addition, the invention further provides a preparation method of the heat-proof magnetic conveyor belt cover rubber. The heat-proof magnetic conveyor belt cover rubber meets the heat-proof property of high-temperature parts conveyed on an iron making and steel making production line, the heated aging damage rate of the conveyor belt can be reduced, and the service life of the conveyor belt can be prolonged; furthermore, metal parts falling on the conveyor belt can be effectively adsorbed, the slippage of the metal parts can be prevented, unnecessary damage can be reduced, the production of next procedure can be favorably carried out, and the working efficiency can be improved.
