(3) in the compound in step (2), add tackiness agent, utilize afterwards stirred vessel to stir 3-4 hour, break into slurry, again slurry drying equipment is dried to 20 minutes, when dry, vacuumize, vacuum tightness is 12Pa, and dry disposed slurry becomes the porous particle of 0.1-0.2mm;
(4) particle in step (3) is put into mould, then mould is put into hot pressing furnace, in stove, temperature is controlled at 1000-1200 ℃, pressure remains on 40MPa, heat-insulation pressure keeping 4 hours, along with temperature in hot pressing furnace is cooled to room temperature, gets final product to such an extent that contain carbon fiber false tooth blanks.
The invention has the beneficial effects as follows: a kind of carbon fiber false tooth blanks that contains of the present invention, due to contain its intensity of carbon fiber good, corrosion-resistant might as well, high temperature resistant and low weight, carbon fiber can be well and zirconium dioxide, alchlor mechanical bond.
In order to obtain better effect, above scheme can also be done following improvement:
Further, described carbon fiber is to carry out surface treatment dry carbon fiber.
Further, described surface treatment is that liquid-phase oxidation+anodised compound surface facture is carried out electrochemicial oxidation to carbon fiber.It is that 60 ℃, concentration are in 5% aqueous nitric acid bath that carbon fiber is imported to temperature by the deflector roll of pottery system, on carbon fiber, add positive voltage, negative plate is set in bath, and betwixt by the electric current of 1A, approximately 2 minutes, the above-mentioned carbon fiber through electrochemicial oxidation is washed, and in vacuum drier, temperature is at 200 ℃, to carry out drying treatment within 1 minute, to obtain surface treatment dry carbon fiber.
To carbon fiber carry out oxidized surface process be for improve its binding property and and the carbonization phenomenon of metal oxide compound tense, although carbon fiber comparatively speaking erosion resistance is relatively good, but its surface is imposed to strong corrosion, process, surface still can corrosion and also internal structure also may be destroyed.Through adopting liquid-phase oxidation+anodised compound surface facture, carbon fiber is carried out after electrochemical treatment, the surface corrosion-resistant erosion of carbon fiber has improved, the physical strength of carbon fiber also can brought into play larger effect with other materials compound tense, carry out compound tense with zirconium dioxide, aluminium sesquioxide like this, the phenomenons such as metallic carbide can not occur again.
Further, described tackiness agent is PP tackiness agent.This tackiness agent good corrosion resistance, bounding force are strong, can with metlbond and insoluble molten, waterproof, nondiscoloration.
