Problems solved by technology

However, commonly used pozzolanic fillers, such as fly ash, blast furnace slag powder, silica fume, etc., can only react with calcium hydroxide in large pores above the micron level, which is not enough to effectively block the efflorescence channel
Therefore, the improvement of the ubiquitous alkaloid problem is very limited

Abstract

The invention discloses an anti-efflorescence high-strength inorganic artificial stone material and a preparation process thereof for a decorative plate. The anti-efflorescence high-strength inorganicartificial stone material is prepared from the following components in parts by weight: 0.5-1.5 parts of an inorganic cementing material, 1.5-3.0 parts of sandstone aggregate, 0.003-0.025 parts of awater reducing agent, 0-0.1 parts of inorganic pigment, 0-0.1 parts of special fiber and 0.16-0.25 parts of water. When the anti-efflorescence high-strength inorganic artificial stone material is usedfor preparing a decorative plate, the efflorescence resistance of a cement-based material plate can be greatly improved, the cement-based material plate has ultrahigh strength and good weather resistance, decorative plates with various stone textures and colors can be easily obtained, and the manufacturing process is simple and efficient.

Description

technical field [0001] The invention belongs to the field of new building decoration materials, and in particular relates to an anti-pantherine high-strength inorganic artificial stone material and its preparation process for decorative boards. Background technique [0002] Panels made of natural stone are widely used to decorate floors and walls. As the country vigorously promotes the construction of ecological civilization, the development of stone materials along the coast, along the lake, along the river, and along the forest has been gradually banned. Some provinces and cities have issued the "Ecological Red Line", and a large number of stone mines have been closed. As a substitute for natural stone, artificial stone has developed strongly in recent years. Artificial stone is divided into two categories from the type of material: resin-based artificial stone and cement-based artificial stone. [0003] Resin-based artificial stone uses unsaturated polyester resin as th...
