Method of making articles in form of slabs or blocks using acrylic binder / 2421422
Invention relates to a novel method of making articles in form of slabs, porous slabs, blocks made from a conglomerate consisting of pieces of stone. The method is based on the existing technology of compaction by means of vacuum compression and involves preparation of a mixture consisting of a granulate and binder which is an aqueous dispersion of an acrylic prepolymer. The granulate is selected from stone-like materials. The mixture also contains a finely dispersed inorganic aggregate. The mixture is deposited in form of a layer onto a substrate or inside a mould and is compacted via vacuum vibro-compression. Further, the binder which is present in the moulded article is hardened. At the step for compaction using vacuum vibro-compression, the article hardens in conditions which enable to prevent removal of water from the mixture due to evaporation. When making porous slabs, at the compacting step, the article hardens in conditions which enable to remove water from the mixture. When making blocks, the mixture is deposited only inside the mould. When using the method, blocks can also be made, which can then be sawed.
