Abstract

The invention discloses a surface protecting coating of a stone. The coating is composed of the following components in parts by weight: 1000 parts of cyclohexane, 5-15 parts of triethylene glycol methyl ether, 10-100 parts of nano silicon dioxide, 80-180 parts of vinyl blocked dimethyl siloxane, 2-15 parts of perfluoromethyl vinyl ether and 20-60 parts of a polystyrene-polybutadiene-polystyrene block copolymer. After applying the surface protecting coating of the stone disclosed by the invention, effects of blocking moisture migration and diffusion of salt and alkali can be exerted, so that various diseases such as water spots, saltpetering, rust and cracks after a natural stone is in contact with cement mortar can be avoided better, the bonding strength can be increased, and the service life of the natural stone, in particular of the natural stone for building decoration, is greatly prolonged. The coating has quite good economical benefit and application prospect.
