Moisture-proof coating composition for antimoist coating of glass beads for road pavement manufacturing method of the composition and forming method of moisture-proof glass beads for road pavement

摘要

The present invention is a moisture-proof coating liquid for moisture-proof coating of glass grains for road marking paint, tetraethyl orthosilicate (Tetraethyl orthosilicate); At least one material selected from the group consisting of phenyl trimethoxysilane and dimethyl methoxysilane; Acid; Water (H ₂ O); And an organic solvent, wherein the at least one material selected from the group consisting of phenyltrimethoxysilane and dimethylmethoxysilane and the tetraethyl orthosilicate form a molar ratio of 0.1:1 to 1:1. It relates to a moisture-proof coating solution, a method for manufacturing the same, and a method for forming a moisture-proof coating glass grain for road sign paint. According to the present invention, when exhibiting excellent water repellent properties and coated on the glass grain for road sign paint, the glass grain can be uniformly sprayed from the nozzle during the lane operation.
