Microcrystalline glass with strong breaking resistance and preparation method thereof

Abstract

The invention discloses microcrystalline glass with strong breaking resistance, which is formed by the following raw materials in parts by weight: 25-30 parts of coal gangue, 20-30 parts of quartz sand, 15-20 parts of fly ash, 10-15 parts of silicon dioxide, 10-15 parts of calcium carbonate, 10-15 parts of alabaster, 6-8 parts of zinc oxide, 5-7 parts of aluminum oxide, 5-7 parts of barium oxide, 3-4 parts of potassium oxide, 3-4 parts of table salt, 2-4 parts of magnesium fluoride, 2-3 parts of calcium fluoride, 2.5-3 parts of wood charcoal, 3-4 parts of clay, 2-3 parts of boron oxide, 2-3 parts of lithium oxide, 2.5-3 parts of tree ash, 2-3 parts of plant ash, 2-3 parts of sodium oxide, 0.25-0.4 part of potassium feldspar, 0.15-0.3 part of sodium tetraborate, 0.15-0.3 part of vanadium pentoxide and 0.15-0.2 part of zirconium dioxide. The microcrystalline glass disclosed by the invention has the advantages of good flatness, high mechanical strength, great hardness, and good heat resistance, bending strength, corrosion resistance and wear resistance; and the product can be made into various types of pipes and sheet materials and can be widely applied to wear-resisting and corrosion-resisting materials and building decoration materials of buildings.

Description

technical field [0001] The invention mainly relates to a glass-ceramic and a preparation method thereof, in particular to a glass-ceramic with strong bending resistance and a preparation method thereof. Background technique [0002] Glass-ceramic, also known as glass-ceramic, is a new type of material developed by combining glass and ceramic technology. Such as high mechanical strength, corrosion resistance, heat resistance, wear resistance, good oxidation resistance, excellent electrical properties, adjustable expansion coefficient, good thermal stability, etc., and is superior to natural stone and ceramics, and can be used for building curtain walls and indoor high-end decoration , can also be used as structural materials for machinery, insulating materials for electronics and electricians, bottom plate materials for large-scale integrated circuits, heat-resistant series of microwave ovens, chemical and anti-corrosion materials and mine wear-resistant materials, etc., ...

AI Technical Summary

Problems solved by technology

Because glass-ceramics can use ore, industrial tailings, metallurgical slag, fly ash, coal gangue, etc. as the main raw materials for production, and there is no pollution in the production process, and the product itself has no radioactive pollution, so it is also called an environmentally friendly product or green material. , the surface layer and inner layer of traditionally produced glass-ceramics often have a large number of technical pores, and the flexural strength and water resistance are not strong, which limits the application field of glass-ceramics
