Claims24
An engineered stone artificial marble comprising a base and a pattern provided in the base,
- wherein the pattern comprises a vein pattern,
- 50% or more of the vein pattern has a width of 5 mm to 50 mm on a surface where the vein pattern is most present of surfaces of the artificial marble, and
- wherein in a cross section including a maximum thickness of the vein pattern among cross sections in a direction perpendicular to a plate surface of the artificial marble, an area of the vein pattern in which a thickness of the vein pattern is 10% or greater of a total thickness of the artificial marble is 50% or greater of an area of the entire pattern.
An engineered stone artificial marble comprising a base and a pattern provided in the base,
- wherein the pattern comprises a vein pattern, and
- wherein when an arbitrary square region is equally divided into 20×20 surfaces on a surface where the vein pattern is most present among surfaces of the artificial marble and then a straight line traversing the vein pattern in a width direction and having both ends located on the base is drawn, or if it is not possible to draw a straight line whose both ends are located on the base, a straight line with one end on the base and the other end on the vein pattern is drawn, an area of divided surfaces having a vein pattern having two or more peaks on a graph of 5-section moving average values of a gray value measured along the straight line is less than 30% of an area excluding the divided surfaces, on which only the vein pattern is present or only the base is present, in the square region.
An engineered stone artificial marble comprising:
- a first region formed by first distribution on a surface;
- and
- a second region formed by second distribution after the first distribution,
- wherein the first region and the second region are different in composition from each other, and the first region and the second region are not substantially mixed.
A screening mask comprising a flat plate portion and one or more openings.
A manufacturing method of an artificial marble comprising:
- molding a base composition into a mold;
- placing a screening mask and a pattern mold over the base composition, the screening mask including a flat plate portion and one or more openings, the pattern mold including a concave portion and one or more convex portions, the convex portions corresponding to the openings of the screening mask and being insertable into the openings;
- pressing the pattern mold to compress the base composition;
- removing the pattern mold to form one or more grooves in the base composition;
- putting a pattern forming composition into the grooves and removing the screening mask;
- manufacturing an artificial marble flat plate by compressing the composition in the mold while applying vacuum and vibration to the composition;
- and
- applying heat to the artificial marble flat plate before curing, and curing the artificial marble flat plate.
