MAINTENANCE-FREE STONE TILE, COATING AGENT THEREFOR, AND METHOD FOR PRODUCING THE TILE

摘要

A maintenance-free stone tile is provided in which a super hard coating film having a pencil hardness corresponding to 12H or more (preferably to 12 to 15H) is used to produce a finish having a deep material feeling and a high quality, and glossiness of 80 or more, and be further able of keeping the coating layer good in water resistance, antifouling property, slipperiness, adhesiveness and no crack, over a long term, on a surface of a stone tile, such as a marble, artificial stone, terrazzo or ceramic tile. The tile is a stone tile having an inorganic coating layer causing a surface of the stone to have a pencil hardness of 12H or more and a mirror surface glossiness of 80 or more.

主权项

1. A maintenance-free stone tile, comprising a stone tile and an inorganic glassy protective coating layer formed on a surface of the stone tile,
wherein the layer has an outer surface having a pencil hardness of a value corresponding to 12H or more in the case of measuring the outer surface on the basis of correlative data between a pencil hardness test and an abrasion resistance test; a thickness of the coating of 20 to 50 μm; a surface roughness Rmax of 0.8 s or less; a mirror surface glossiness of 80 or more; dry slip properties of 0.6 or more; a wet slipperiness of 0.5 or more; and a surface resistance value of 1011 Ω or less.
