Abstract
The invention relates to a rubber material of a strong acid resistant rubber roll for non-ferrous metal chemical mineral processing equipment and a preparation method. The rubber material has resistance to strong acid corrosion and wear, high elasticity (low compression deformation), and good mechanical property, self-adhesion and mutual adhesion. The rubber material comprises 100 parts of ethylene-propylene-diene monomer, 10-25 parts of masterbatch, 29-31 parts of N-33 carbon black, 49-51 parts of N-770 carbon black, 1.9-2.1 parts of antioxidant RD, 1.4-1.6 parts of antioxidant MB, 24-26 parts of 2280# paraffin oil, 4.4-4.6 parts of di-2,5 and 1.4-1.6 parts of triallyl isocyanurate. The rubber material has the advantages that firstly, the rubber material of the roll can withstand the corrosion of ore pulp fluid; rubber is free from oxicracking and thermal aging by the action of acid leaching liquor; the damage of the rubber roll cannot be accelerated; the rubber roll is long in service life; furthermore, the material has the highly reliable wear resistance; and secondly, the material has the good mechanical property, self-adhesion and mutual adhesion.
Description
technical field [0001] The invention relates to a strong-acid-resistant rubber roller for non-ferrous metal chemical beneficiation equipment, which not only has strong acid corrosion resistance and wear resistance, but also has high elasticity (low compression set), good mechanical properties, and good self-adhesive and mutual-adhesive properties. The rubber material and the preparation method belong to the field of strong acid-resistant rubber roller rubber material manufacturing. Background technique [0002] Chemical beneficiation is based on the differences in the chemical properties of minerals and mineral components, using chemical methods to change the mineral composition, and then using corresponding methods to enrich useful components. The processing objects of chemical beneficiation are generally difficult-to-separate mineral raw materials that cannot be processed or are uneconomical by physical beneficiation or traditional smelting methods under the current techni...
