Patent DE-4001504-A1 (DE)
Inventor: RODRIGUEZ RUBIO GONZALO
IPC: B28B17/02
Filed: 1990-01-19
Abstract: It consists of decanting ground frits in successive layers until a certain volume is obtained. White or colored clay can also be used in the decanting in intermediate layers as long as their melting point is the same as that of the frits. The decanting is effected for periods of time with intermediate downtime in order to let the material settle. In the event of using frits exclusively, it is possible to include a binder in the decantation bath. The product obtained is a muddy block from which slabs with a variable thickness are cut in the transversal direction of the block either for incorporation or a ceramic bisque or sandstone support or without support for decoration, which is subjected to firing for its crystallization.

Abstract: The invention relates to a process for producing a multi-layer coating in which use is made of a transparent aqueous covering composition containing polyacrylate resin as a binder. The polyacrylate resin is obtained by successively or alternately in partial quantities adding to an organic solvent a mixture of a carboxyl group-containing ethylenically unsaturated monomer (a1) and a carboxyl group-free monomer (a2) and a mixture (b) of carboxyl group-free (meth)acrylic acid esters, hydroxyl group-containing ethylenically unsaturated monomers and possibly other ethylenically unsaturated monomers and polymerising them in the presence of a radical-forming initiator and, after completed polymerisation, neutralising the polyacrylate resin obtained and dispersing it in water. The nature and quantities of (a1), (a2) and (b) are selected so that the polyacrylate resin has a hydroxyl number from 40 to 200, an acid number from 20 to 100 and a glass transition temperature (TG) of -40 to +60  DEG C.
