Problems solved by technology

[0003] However, the current magnesite products on the market are prepared by flow injection molding, rolling, extrusion, etc., and the existing flow injection molding method is limited by the fluidity of the slurry, and the preparation process is single. The pattern texture design of magnesia bricks is difficult to control, resulting in the random uncertainty of the pattern texture of the prepared magnesite bricks, which cannot be precisely controlled, resulting in unqualified decorative effects. The phenomenon of high cost and waste of resources, and the problems of low bulk density, uneven hardness, low flexural strength and high water absorption rate of magnesite bricks produced by slip injection molding, so the quality of magnesite bricks is difficult to control and Can not meet consumers' high-quality requirements for magnesite bricks

Abstract

The invention provides a magnesite green brick and a preparation method thereof. The preparation method includes the following steps: step 1), evenly mixing raw materials of magnesite boards into slurry, initially curing the slurry, and subjecting the initial curing material, obtained from initial curing, to crushing and sieving to obtain powder particles for board forming; step 2), distributing the obtained powder particles for board forming, and subjecting the powder particles to compression molding to obtain a magnesite board blank. The magnesite green brick prepared according to the method has high strength, green bricks with preset patterns and textures can be formed while magnesite materials are mixed with powder in different colors, and only random textures with blurry edges can be formed while conventional magnesite-material slurry flowing based molding is adopted.

Description

technical field [0001] The invention relates to the technical field of magnesite materials, in particular to a method for preparing magnesite adobe and the prepared adobe. Background technique [0002] Magnesite material is a pure inorganic adhesive material, which has excellent properties such as environmental protection, non-toxic, non-radiation, fire resistance, aging resistance, acid and alkali resistance, etc. It is easy to realize special-shaped shapes, solidifies at low temperature, and does not require high-temperature sintering, so it is widely used in production. . [0003] However, the current magnesite products on the market are prepared by flow injection molding, rolling, extrusion, etc., and the existing flow injection molding method is limited by the fluidity of the slurry, and the preparation process is single. The pattern texture design of magnesia bricks is difficult to control, resulting in the random uncertainty of the pattern texture of the prepared mag...
