Reactive liquid ceramic binder resin
View Patent ↗A reactive liquid ceramic binder suitable for the production of ceramic products from ceramic powders is provided. The reactive liquid ceramic binder contains organo-modified siloxane compounds, wherein the liquid organo-modified siloxane compounds contain organoalkoxysiloxane units according to general formula (I) wherein R 1 =alkyl radical and/or aryl radical, R 2 ═H and/or alkyl radical with 1 to 4 carbon atoms, a≧0 and ≦2, and b<0 and ≦3, with the proviso that a+b≧1 and ≦4.
1. A ceramic mix comprising ceramic particles and at least one organo-modified siloxane compound which is a liquid at 25° C., said at least one organo-modified siloxane compound binds said ceramic particles together forming said ceramic mix and has organoalkoxy-siloxane units according to general formula (I)
wherein
R 1 =an alkyl radical having from 1 to 4 carbon atoms,
R 2 =an alkyl radical with 1 to 4 carbon atoms,
a≧0 and ≦2, and
b>0 and ≦3,
with the proviso that a+b≧1 and <4, and R 2 is not H.
2. The ceramic mix as claimed in claim 1 , further including nanoscale metal oxides.
3. The ceramic mix as claimed in claim 1 , wherein the ceramic mix has a powder density of 500 g/l to 2000 g/l.
4. The ceramic mix as claimed in claim 1 , further including at least one additive, said at least one additive is selected from an organic binder, an inorganic binder or mixtures thereof.
5. The ceramic mix of claim 1 wherein no water is added to the ceramic mix.
6. A ceramic mix comprising ceramic particles and at least one organo-modified siloxane compound which is a liquid at 25° C., said at least one organo-modified siloxane compound binds said ceramic particles together forming said ceramic mix and has organoalkoxy-siloxane units according to general formula (I)
wherein
R 1 =methyl or ethyl,
R 2 =an alkyl radical with 1 to 4 carbon atoms or a mixture thereof,
a≧0 and ≦2, and
b>0 and ≦3,
with the proviso that a+b≧1 and <4, and R 2 is not H.
7. The ceramic mix of claim 6 wherein no water is added to the ceramic mix.
