Rock sheet and plate mix based on volcanic rock particles useful for building and decoration

A mix of for manufacturing a rock laminate, which comprises:

• volcanic rock particles having diameters between 1 micron and 5 mm present in an amount of greater than 50% of the mix;
• an agglutinating agent comprising a polymer mixture in an amount sufficient to act as a binder for the rock particles, with the mixture comprising a water dispersible block copolymer and a vinyl polymer in a weight ratio of 1:4 to 3:2, wherein the block copolymer is a butyl acrylate and styrene co-polymer, and the vinyl polymer comprises a vinyl acrylic co-polymer present in an amount of about 3 to 10% by weight of the mix;
• and a polyvinyl acetate resin present in an amount of about 1 to 5% by weight of the mix;
• a silicate compound in an amount sufficient to stabilize the mix;
• and
• water in an amount to moisten and fluidize the mix.

A mix for manufacturing a rock laminate, which comprises:

• volcanic rock particles in a plurality of different size fractions having diameters between 1 micron and 5 mm and present in an amount of 58% to 88% by weight of the mix, wherein the rock particles are present in at least three fractions including a first fraction having a particle size of 1 to 5 microns and being present in an amount of 18 to 28% by weight of the mix;
• a second fraction having a particle size of 0.25 mm to 1.75 mm and being present in an amount of 10 to 20% by weight of the mix;
• and a third fraction having a particle size of 2 mm to 5 mm and being present in an amount of 30 to 40% by weight of the mix;
• an agglutinating agent comprising a polymer mixture in an amount sufficient to act as a binder for the rock particles, wherein the agglutinating agent is emulsified, is present in an amount of 8 to 25% by weight of the mix and comprises a water dispersible block copolymer and a vinyl polymer in a weight ratio of 1:4 to 3:2;
• a silicate compound of a magnesium hydrosilicate in an amount of about 1 to 5% by weight of the mix to stabilize the mix;
• and
• water in an amount of about 15 to 30% by weight of the mix to moisten and fluidize the mix.
