The preparation method of the sealing-ring of described horizontal spiral centrifuge thruster inwall may further comprise the steps:
(1) prepare raw material according to the material component of described each weight part, wherein modified nano zinc oxide only adds 2/3 of above-mentioned weight part, and each raw material is put into Banbury mixer, by the Banbury mixer synthetic rubber, and filters;
(2) synthetic rubber after detection is filtered is opened the type of being smelt with detecting qualified synthetic rubber by mill, the rubber after the moulding is put into the mould of vulcanizing equipment, at pressurization 175～180Kgf/cm again
2, be warming up under 165～170 ℃ the condition, add remaining 1/3 nano zine oxide, rubber is carried out sulfidizing, the time length is 6-7 minutes;
(3) rubber of step (2) sulfidizing being crossed carries out deburring, check, packing, warehouse-in.
The preparation method of described modified nano zinc oxide is: the oxalic acid take mass ratio as 1:1 and zinc acetate are raw material, at first synthesize precursor two oxalic acid hydrate zinc with solid-phase reaction, through 450-470 ℃ of thermolysis 2-3h, obtain nano zine oxide again; With the nano zine oxide ultra-sonic dispersion in the dehydrated alcohol of 5-10 times of its quality, obtain dispersion liquid, then the coupling agent dicumyl peroxide with its quality 3-5% adds in the above-mentioned dispersion liquid, back flow reaction is 1～2 hour under 80～90 ℃ of temperature, obtain the coupling agent modified nano zine oxide-alcohol suspension with reactive group after the reaction, then filter, centrifugation filtrate obtains modified nano zinc oxide.
Advantage of the present invention:
