Abstract
The present invention provides high density artificial stone with physical properties similar to those of natural stone and having excellent and beautiful external appearance as well as a method to produce same. More particularly, the present invention provides high density artificial stone consisting of 10 to 70 mesh inorganic fine particles from natural stone and the like which are mixed with 100 mesh or above inorganic very fine particles to the weight ratio ranging from 0.5:1 to 5:1, jointly accounting for at least 85% of the weight of the final product, containing 15% or less resins, wherein each raw material component is uniformly distributed and the fine particles from natural stone and the like are exposed on the surface of the product.

High density artificial stone consisting essentially of acrylic or methacrylic resins and 10 to 70 mesh inorganic fine particles and inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, which particles jointly account for at least 85 wt % of the final product, and wherein said particles are exposed on the surface of the final product.
High density artificial stone consisting essentially of acrylic or methacrylic resins and 10 to 70 mesh inorganic fine particles and inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, jointly accounting for at least 85 wt % of the final product and which also contains glass fibers equivalent to 1 to 15 wt % of the inorganic fine particles, and wherein said particles are exposed on the surface of the final product.
A method of producing high density artificial stone by preparing a mixture of acrylic or methacrylic resins and 10 to 70 mesh inorganic fine particles and inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, jointly accounting for at least 85 wt % of the final product, placing said mixture into a mold for forming and removing the resins on the surface of the molded product by softening or melting said product in an organic solvent, or mechanically, in order to allow the particles to be exposed on the surface of the molded product.
A method of producing a high density artificial stone by preparing an acrylic or methacrylic mixture of resins and 10 to 70 mesh inorganic fine particles and inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, jointly accounting for at least 85 wt % of the final product, placing said mixture into a mold for molding, and exposing the particles on the surface of the molded product by applying a water jet to the surface of said molded product.
High density cylindrical artificial stone consisting essentially of acrylic or methacrylic resins and 10 to 70 mesh inorganic fine particles inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, jointly accounting for at least 85 wt % of the final product, said mixture being molded and solidified in a cylindrical form, wherein the end product has a polished or roughened surface.
A method of producing high density cylindrical artificial stone which comprises preparing a mixture of acrylic or methacrylic resins and 10 to 70 mesh inorganic fine particles and inorganic very fine particles of 100 mesh or above mixed to a ratio ranging from 0.5:1 to 5:1 by weight, jointly accounting for at least 85 wt % of the final product, placing the resultant mixture into a rotating cylindrical molding box for centrifugal molding and solidification to produce a molded product, followed by polishing or roughening the surface of the molded product.
