Rubber material of strong acid resistant rubber roll for non-ferrous metal chemical mineral processing equipment and preparation method

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.
