5. the preparation method of the wear-resisting resistance to erosion rubber lining of the Rotating fields according to claim 1,2,3 or 4, is characterized in that, comprise the following steps:
1) pull into diameter after aramid fiber glass and nylon fibre being melted respectively and be no more than 0.1mm filament, then ratio in accordance with claim takes each component of composition rubber substrate and surface abrasion resistance rubber, again formation rubber substrate is mixed into material A and material B with different ratios respectively with the component of surface abrasion resistance rubber skeleton, to be respectively used to the skeleton preparing rubber substrate and surface abrasion resistance rubber;
2) respectively by step 1) for the preparation of the material A of rubber substrate and surface abrasion resistance rubber skeleton and material B send into carry out once in two banburies mixing, melting temperature is 150-170 degree Celsius, pressure is 25-30MPa, rotor speed is 60rpm, mixing 30s-60s, and before mixing, first to for the preparation of the silicon carbide micro-powder added in the material B of surface abrasion resistance rubber skeleton in additive or zirconium carbide micropowder and alumina powder, send in banbury mixing after stirring again;
3) material A adds extraordinary anti-corrosive rubber wherein after once mixing, again carries out mixing, and melting temperature is 150-170 degree Celsius, pressure is 40-42MPa, and rotor speed is 60rpm, mixing 30s-60s, and cooling obtains rubber substrate naturally, for subsequent use;
4) by for the preparation of all the other additives of surface abrasion resistance rubber and extraordinary anti-corrosive rubber mixing, melting temperature is 160-170 degree Celsius, pressure is 35-45MPa, and rotor speed is 90rpm, and mixing 30-60s is for subsequent use;
5) by the extraordinary anti-corrosive rubber after mixing in step 4) and step 2) in mixing after material B mix after again mixing, melting temperature is 165-170 degree Celsius, pressure is 40-42MPa, rotor speed is 90rpm, mixing 2-3min, and mixing end naturally cools afterwards and obtains surface abrasion resistance rubber;
6) surface abrasion resistance rubber obtained in the rubber substrate obtained in step 3) and step 5) is sticky and form and obtain product by hot vulcanization process.
