Being injection molding possible with the injection molding converted timber charge for porous ceramic production, and production mannered null

摘要

PROBLEM TO BE SOLVED: To provide an injection molding material for manufacturing a porous ceramic, having excellent flowability when injection-molded, and hardly generating a crack when degreased and when fired.SOLUTION: This injection molding material for manufacturing the porous ceramic is obtained by blending silica powder having 50 μm of average particle size, a polyethylene gylcol and a paraffin wax at 80:10:10 of weight ratio, and by adding a coupling agent (3-methacryloxypropyltrimethoxysilane) of which the functional group is methacryl group, at 0.1-3 wt.% with respect to the silica powder, and then kneading at 120°C for 1-3 hours.
