Abstract

The invention discloses a preparation method of environment-friendly lead-cadmium-free red glass. Basic components and a stable colorant are used as raw materials. The method includes the steps that firstly, the stable colorant and sodium silicate are mixed evenly and subjected to low-temperature pretreatment, and then the mixture and the basic components are mixed evenly to obtain a mixed raw material; the mixed raw material is molten at a rising temperature to form a melt, and after temperature reduction, forming and natural cooling to the room temperature, basic glass is obtained; the basicglass is calcined for secondary color development, and then the environment-friendly lead-cadmium-free red glass is obtained. Besides, the invention discloses the product prepared by the preparationmethod of the environment-friendly lead-cadmium-free red glass. The preparation method is simple and easy to implement, the technological process is stable and reliable, the problems that in the priorart, a founding technology is complex and color development is not stable are effectively solved, and the obtained product has high visible light transmittance and can be widely applied to many fields such as building materials, artistic decoration and optical application.

Description

technical field [0001] The invention relates to the technical field of glass materials, in particular to a method for preparing an environment-friendly lead-cadmium-free red glass suitable for the fields of building materials, art decoration, and optical applications, and the prepared product. Background technique [0002] Red is the color of celebration. Red glass is not only commonly used in building materials and optical applications, but is also currently used in art decoration, jewelry necklace products, imitation rubies and other fields. It has very broad application prospects and market potential. However, as people pay more and more attention to environmental protection issues, traditional red glass has attracted more and more attention regardless of its material, components or production process. As we all know, in order to obtain bright red glass, it is necessary to add a colorant to the components of the glass to achieve stable coloring of the glass. At present, ...
