Also contain calcined kaolin micropowder, the content of calcined kaolin micropowder is 0.1-0.2%.
4. the wear-resisting resistance to erosion rubber lining of Rotating fields according to claim 1 preparation method it is characterised in that include with
Lower step:
1) pull into diameter after aramid fiber glass and nylon fibre being melted respectively and be less than 0.1mm filament, then according to claim 1
Described ratio weighs composition rubber substrate and each component of surface abrasion resistance rubber, then will constitute rubber substrate and surface abrasion resistance rubber
The component of glue skeleton mixes into material a and material b respectively in different proportions, resistance to be respectively used to preparation rubber substrate and surface
The skeleton of rubber milling；
2) will be used in step 1) preparing the material a and material b feeding two of rubber substrate and surface abrasion resistance rubber skeleton respectively
Once kneaded in banbury, melting temperature be 150-170 degree Celsius, pressure be 25-30mpa, rotor speed is
60rpm, kneads 30s-60s, and before mixing, first adds additional in the material b for preparing surface abrasion resistance rubber skeleton
Silicon carbide micro-powder in agent or zirconium carbide micropowder and alumina powder, are re-fed into mixing in banbury after stirring；
3) material a is added thereto to extraordinary anti-corrosive rubber after once kneading, and is kneaded again, melting temperature is 150-
170 degrees Celsius, pressure be 40-42mpa, rotor speed be 60rpm, knead 30s-60s, natural cooling obtains rubber substrate, standby
With；
4) will be used for preparing remaining additive of surface abrasion resistance rubber and extraordinary anti-corrosive rubber mixing, melting temperature is 160-
170 degrees Celsius, pressure be 35-45mpa, rotor speed be 90rpm, knead 30-60s, standby；
5) by extraordinary anti-corrosive rubber and step 2 after kneading in step 4)) middle knead after material b mix after knead again,
Melting temperature is 165-170 degree Celsius, pressure is 40-42mpa, and rotor speed is 90rpm, kneads 2-3min, after mixing terminates
Natural cooling obtains surface abrasion resistance rubber；
6) by the surface abrasion resistance rubber being obtained in the rubber substrate being obtained in step 3) and step 5) pass through hot vulcanization process glue and
Form and obtain product.
