The preparation method of the sealing ring of described horizontal spiral centrifuge propeller inwall, comprises the following steps:
(1) prepare raw material according to the material component of described each weight portion, wherein modified nano zinc oxide only adds 2/3 of above-mentioned weight portion, and each raw material is put into banbury, by banbury synthetic rubber, and filters;
(2) detect the synthetic rubber after filtering, open by mill the type of being smelt by detecting qualified synthetic rubber, then the rubber after moulding is put into the mould of vulcanizing equipment, at pressurization 175～180Kgf/cm2, be warming up under the condition of 165～170 DEG C, add remaining 1/3 nano zine oxide, rubber is carried out to vulcanizing treatment, the duration is 6-7 minutes;
(3) rubber of step (2) vulcanizing treatment being crossed carries out deburring, inspection, packaging, warehouse-in.
The preparation method of described modified nano zinc oxide is: the oxalic acid taking mass ratio as 1:1 and zinc acetate are raw material, first synthesizes predecessor two oxalic acid hydrate zinc with solid-phase reaction, then through 450-470 DEG C of thermal decomposition 2-3h, obtains nano zine oxide; By in the ultrasonic nano zine oxide absolute ethyl alcohol that is scattered in 5-10 times of its quality, obtain dispersion liquid, then the coupling agent cumyl peroxide of its quality 3-5% is added in above-mentioned dispersion liquid, back flow reaction 1～2 hour at 80～90 DEG C of temperature, after reaction, obtain the coupling agent modified nano zine oxide-alcohol suspension with reactive group, then filter, centrifugation filtrate, obtains modified nano zinc oxide.
Advantage of the present invention:
The present invention, by adding modified nano zinc oxide as vulcanizing agent, has accelerated curingprocess rate, has improved crosslinking degree, has increased the mechanical property of rubber product, has greatly strengthened stability and the ageing resistance of rubber; Modified nano zinc oxide particle is small, and large with the bonding area of sizing material, additive capacity is little, has saved the consumption of resource, and modified nano zinc oxide can also be served as reinforcing agent, makes rubber have good wearability, resistance to tearing and elasticity.
