Abstract
The invention relates to a process for manufacturing artificial stone boards especially suitable for outdoors comprising the phases of: grinding of the different materials with varied granulometry forming the filler, containing the resin with the catalyst and optionally the resin, a moulding and compaction phase of the obtained paste by vibro-compression under vacuum, and a hardening phase by polymerization of the resin by means of heat, ending with a cooling and polishing phase.
Claims25
A process for manufacturing artificial stone boards suitable for outdoors comprising:
- (A) grinding materials having a varied granulometry so as to form a filler,
- (B) admixing a polymerizable resin with a catalyst and optionally a colorant,
- (C) mixing the products of steps (A) and (B) until homogenization of the materials with the resin is achieved and so as to obtain a paste,
- (D) moulding and compacting the paste of step (C) by vibro-compression under vacuum,
- (E) hardening the resulting product of step (D) by polymerization of the resin by means of heat, and
- (F) cooling and polishing the resulting hardened product of step (E),
- wherein the polymerizable resin is a liquid methacrylate resin having a viscosity of between 200 and 2000 centipoises
