Leadless cadmium-free reinforced glass pigment flux

Abstract

The invention relates to a lead and cadmium free toughened glass pigment flux, which can be prepared into glass pigment for decorating toughened glass. The composition of the burden by weight proportion is: 15-40% of SiO2, 5-30% of B2O3, 1-5% of Al2O3, 1-10% of TiO2, 5-20% of ZnO, 1-5% of ZrO2, 1-5% of SnO2, 1-15% of Li2CO3, 1-5% of K2O, 1-5% of Na2O, 1-5% of CaCO3and 0-5% of Ba2CO3. The pigment flux has the advantages of no lead, no cadmium, non-toxicity, safety, reliability, good chemical stability, pure color generation, gorgeous color, high glossiness and high quality, which is suitable for red, blue, green and yellow agent and can be manufactured into glass pigment for decorating toughened glass or other glassware. Since the cost is low, the pigment flux is beneficial for large-scale popularization.

Description

technical field [0001] The invention relates to a lead-free and cadmium-free tempered glass pigment flux, which is made into a glass pigment for tempered glass decoration. Background technique [0002] Tempered glass pigments are pigments printed on the surface of glass during the tempering process of glass (tempering temperature 680-720°C). The tempered glass pigment is similar to the melting point of glass, and when it melts on the glass, its color is mainly black and white, and there are other colors such as red, blue, green, and yellow. Tempered glass is mostly used in automobile glass, architectural glass, refrigerator inner partition, microwave oven glass screen and tempered glass utensils, etc. [0003] The flat glass produced by the fluorine process has low strength and is easy to break. Especially when it is used in the fields of automobiles and construction, the chance of people colliding with the glass is relatively high, and the broken glass is easy to hurt peop...

Problems solved by technology

On the other hand, during the mining, smelting and application of lead, the harmful gas of lead is discharged into the atmosphere, causing pollution to the environment and causing harm to human health

And the main raw material lead oxide in the existing toughened glass pigment flux has accounted for 30-55% of total weight, its harm can be imagined, the same as developing lead-free and cadmium-free ceramic pigment flux, research is suitable for the use of tempered glass without Lead and cadmium-free pigment flux is imperative
