Abstract
A preparation method of a screw pump screw pump screw rod rubber lining mould includes: mixing a high strength wear-resistant material with a binder to obtain a mixed slurry; injecting the mixed slurry into a female die for solidification and taking out to form a screw rod rubber lining mould preform; drying and sintering the screw rod rubber lining mould preform to obtain a screw rod rubber lining mould; immersing the screw rod rubber lining mould into a surface treatment liquid for surface heat treatment to form a wear-resistant layer, and cooling down to obtain a final mould. The high strength wear-resistant material is prepared by using a ZnFe2O4 nano-particle reinforced Ti(C,N)-based metal ceramic composite material; the surface treatment liquid includes an aluminum borosilicate whisker/polyimide composite material solution; the high strength wear-resistant material having good strength, good hardness, good fracture toughness, and good wear resistance is prepared and applied.
