Abstract

The invention discloses a preparation method of a corrosion-resistant conveyor belt. The preparation method is characterized in comprising following steps: (1) reaction kettle pretreatment; (2) preparation of modified rubber; (3) rubber material mixing; and (4) milling and sulfuration. A fluorine-containing rubber used for preparing the conveyor belt is prepared via the preparation method; molecular weight distribution is ideal; plasticity is excellent; acid and alkali resistance is excellent; sulfuration speed and fluidity are increased effectively; the obtained conveyor belt possesses excellent heat resistance, wear resistance, and acid and alkali resistance, and is especially suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt production, and in particular relates to a preparation method of a corrosion-resistant conveyor belt. Background technique [0002] Isoprene rubber has good elasticity and wear resistance, excellent heat resistance and good chemical stability. The strength of raw isoprene rubber (before processing) is significantly lower than that of natural rubber, but its quality uniformity and processing performance are superior to natural rubber. Ethylene-propylene rubber is synthesized with ethylene and propylene as the main raw materials, and has outstanding aging resistance, electrical insulation properties and ozone resistance. Ethylene-propylene rubber can be filled with a large amount of oil and carbon black, and the product price is low. Ethylene-propylene rubber has good chemical stability, and its abrasion resistance, elasticity, oil resistance and styrene-butadiene rubber are close. [0003] ...
