Abstract
The present invention relates to an artificial marble having a total transmittance of 6 or greater and 20 or less when the total transmittance is measured using a turbidimeter (NDH 5000 available from Nippon Denshoku) for an artificial marble sample with a size of 7 cm in width, 7 cm in length, and 1.5 cm in thickness.
Claims14
An artificial marble comprising a binder resin, inorganic particles and quartz powder,
- wherein the quartz powder has a SiO2 content of 99.5 to 100% by weight and an alumina content of 0.5% by weight or less,
- wherein the artificial marble comprises 550 to 650 parts by weight of the inorganic particles and 250 to 350 parts by weight of the quartz powder on the basis of 100 parts by weight of the binder resin, and
- wherein the artificial marble has a total transmittance of 6 or greater and 20 or less when the total transmittance is measured using a turbidimeter (NDH 5000 available from Nippon Denshoku) for an artificial marble sample with a size of 7 cm in width, 7 cm in length, and 1.5 cm in thickness.
An artificial marble comprising 550 to 650 parts by weight of inorganic particles and 250 to 350 parts by weight of quartz powder on the basis of 100 parts by weight of a binder resin,
- wherein the binder resin comprises an unsaturated polyester resin, and
- wherein the inorganic particles comprise one or more selected from the group consisting of amorphous silica particles, glass particles including a barium element, crystalline quartz particles, and fused silica particles, and
- wherein a region in which the quartz powder has a SiO2 content of 99.5% by weight or more and 100% by weight or less is included.
