Production method of ceramic ferrule

[0038] The embodiment of the present invention discloses a preparation method of a ceramic ferrule, comprising the following steps:

[0039] Step a) mixing strontium oxide, molybdenum oxide, cerium oxide and zirconia, pre-calcining, then adding oleic acid, magnesia and nano-silicon oxide, mixing by ball milling, and obtaining partially stabilized zirconia powder after sieving;

[0040] Step b) The partly stabilized zirconia powder, dibutyl phthalate, ethylene-vinyl acetate copolymer, zinc stearate, 3-methacryloxypropylmethyldimethoxysilane, poly Olefin elastomer, polypropylene, microcrystalline wax, polyethylene wax and oleic acid are mixed, added to a mixer for mixing, and a gelatinous substance is obtained;

[0041] Step c) compressing the gelatinous substance into tablets, pulverizing it, and obtaining a blank after injection molding;

[0042] Step d) immersing the blank in gasoline, and then performing degreasing treatment and sintering treatment in sequence to obtain a cera

[0087] Example 1

[0088] Step 1. Mix 1 part by weight of strontium oxide, 1 part by weight of molybdenum oxide, 3 parts by weight of cerium oxide and 93 parts by weight of zirconium oxide, pre-calcine at 1000 ° C, add 10 parts by weight of oleic acid , and then add 1 weight part of magnesia and 1 weight part of nano-silicon oxide, carry out ball milling and mixing, and sieve to obtain partially stabilized zirconia powder.

[0089] Step 2. Mix the partially stabilized zirconia powder prepared above with an organic carrier in a certain proportion. The raw materials used in this step include in parts by weight:

[0091] Partially stabilized zirconia powder, dibutyl phthalate, ethylene-vinyl acetate copolymer, zinc stearate, 3-methacryloxypropylmethyldimethoxysilane, polyolefin Elastomer, polypropylene, microcrystalline wax, polyethylene wax, and oleic acid were added into a mixer according to the ratio for mixing. The mixing temperature was 180° C., and the mixing time
