Embodiment 1
[0032] A method for manufacturing a nano-zirconia ceramic LED filament, comprising the steps of:
[0033] Step 1, raw material blending: 92 parts by mass of nano-zirconia and 8 parts of rare earth element oxides are uniformly mixed in a mixer to obtain a blend;
[0034] Step 2, preparing organic colloid: the organic colloid includes the following raw materials in parts by mass: 40 parts of paraffin, 20 parts of polyethylene, 20 parts of ethylene-vinyl acetate copolymer, 3 parts of Span 60, and 8 parts of oleic acid , according to the mass ratio, mix the raw materials, and melt at 200°C to obtain the organic colloid;
[0035] Step 3, mud preparation: According to the number of parts by mass, mix 60 parts of the organic colloid and 100 parts of the blend evenly, heat up to 180°C and mix for 160 minutes, then cool down to 50°C and continue stirring. Until the discharge particle size is not greater than 3mm, mud is obtained;
[0036] Step 4, injection molding: prepare the mud ma...
