Abstract

The invention belongs to the technical field of preparation of novel building materials, and provides single-layer durable building heat insulation Low-E glass and a preparation method thereof. The preparation method comprises the steps of melting at high temperature in presence of auxiliary agents such as a fusing assistant and a clarifying agent under the protection of nitrogen; then, adding silver powder and evenly dispersing to form coating liquid; evenly coating the surface of a glass plate with the coating liquid to form a functional film, and tempering. The preparation method not only simplifies the coating process of the Low-E glass, but also enables the silver powder to be sealed in the glass so as to greatly improve the durability of the Low-E glass; after the preparation methodis adopted, the Low-E glass is effectively protected from mechanical damage and external erosion, and the service life of the Low-E glass is prolonged. Furthermore, the preparation method is simple inpreparation technology and lower in cost, and can realize large-scale production.

Description

technical field [0001] The invention relates to the field of preparation of new building materials, in particular to a single-layer durable building thermal insulation Low-E glass and a preparation method. Background technique [0002] The development of building materials is constantly enriched with the development of society and the continuous improvement of the level of science and technology, from its most basic to meet the needs of life to today's light weight, high strength, high durability, non-toxic and environmental protection, energy saving and environmental protection, earthquake resistance, etc. Many new functional requirements have changed the direction of building materials from passive research and application to the development of new materials with new functions and new uses. [0003] "New building materials", referred to as new building materials, is a new type of building material that is different from traditional building materials such as ash, sand, bri...
