Abstract

The invention discloses glass substrate ceramic dielectric layer glaze. The dielectric layer glaze is prepared from the following raw materials: 50-60 wt% of low-melting-point lead-free dielectric powder, 20-30 wt% of an inorganic metal oxide pigment, 12-18 wt% of water-soluble environment-friendly varnish and 0.5-3 wt% of an auxiliary agent. The ceramic dielectric layer glaze for the glass substrate is high in adhesive force, good in hydrophilicity, high in hardness, scratch-resistant, high-temperature-resistant and corrosion-resistant.

Description

Technical field[0001]The invention belongs to the technical field of coatings, and specifically relates to a ceramicized dielectric layer glaze of a glass substrate and a preparation method thereof.Background technique[0002]The deep processing technology of tempered glass has a long industry history in the fields of construction, home appliances, and automobile protective glass. Tempered glass has flexible plasticity and workability, excellent mechanical and aesthetic properties, but has the following shortcomings:[0003]The traditional decorative processing of transparent tempered glass mainly considers the color and functional processing of the back of the glass, but the surface of the glass body also cannot restrain its reflectivity and smoothness, which limits its wide application;[0004]Traditional home appliance tempered glass decoration generally can only choose to have the glass surface exterior, which is unprotected and does not have a better touch.[0005]By constructing a lay...
