Abstract

The invention provides a preparation method for a super white ceramic vitrified tile produced by using magnesium aluminum silicate as a raw material. The super white ceramic vitrified tile comprises components of potassium feldspar, albite, calcined talc, black clay, a water reducing agent, a lithium feldspar, diopside, an intensifier, washed mud and quartz. The ultralow temperature fast firing vitrified tile belongs to a special ultralow temperature, high-strength, high-hardness, high abrasion-resistance, strong antifouling, low-radiation, environment-friendly, healthy and novel vitrified tile material and product. The technology can reduce firing temperature and shorten a firing period greatly and is favorable for energy conservation and emission reduction of ceramic industry, green manufacturing and low carbon production.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, more specifically, the invention relates to a method for preparing ultra-white ceramic vitrified bricks produced from magnesium aluminum silicate raw materials. Background technique [0002] The ultra-white bricks currently popular in the market should use high-quality feldspar and ball clay and add 2-10% of the radioactive zirconium silicate whitening raw materials. Large, high-quality feldspar, ball soil and other raw materials have become scarce raw materials. At the same time, the use of zirconium silicate whitening raw materials may cause excessive radioactivity, endanger human health, and limit the application of products. At the same time, the whiteness of this type of ultra-white brick is only about 50 degrees, and its texture, strength, and wear resistance cannot meet people's needs for green, healthy and high-quality ultra-white polished bricks. [0003] Chinese ...
