Embodiment 1

[0026] 15% slag powder

[0027] 8% metakaolin

[0028] 3% titanium dioxide

[0029] 10% sodium phosphate solution

[0030] 5% sodium hydroxide solution

[0031] 59% calcium carbonate aggregate

[0032] Put the above materials into the mixer one by one, after mixing evenly, seal and vacuumize, when the vacuum degree reaches -0.095MPa, unload the materials into the mold, vibrate and form in a vacuum state, and after curing at room temperature, cut, After grinding, polishing and protection treatment, the non-cement based inorganic artificial stone plate is prepared. The artificial stone plate belongs to the natural color series, mostly white or off-white. In actual use, various pigments can be added for color matching according to different decoration requirements. The pigments involved in the present invention have no effect on the performance of the plate.

Embodiment 2

Abstract

The invention discloses a novel non-cement-based inorganic artificial stone slab and a preparation method thereof. The novel non-cement-based inorganic artificial stone slab consists of inorganic micropowder, emulsion, an inorganic pigment and an aggregate. The preparation method comprises the following steps of: stirring and mixing the components uniformly, sealing, vacuumizing, releasing into amold when the vacuum degree reaches a certain value, vibrating and pressing in the vacuum state to form a big blank, demolding, processing by procedures such as dragsaw cutting, polishing and protecting, and preparing the inorganic artificial stone facing slab at normal temperature. The gelling system of the non-cement-based inorganic artificial stone slab has a three-dimensional netty macromolecular structure with certain gelling performance and main Al-O-Si bonds, which is formed under the coaction of the inorganic micropowder and emulsion. Through data detection, the non-cement-based inorganic artificial stone slab has the advantages of stable structure, no combustion, ageing resistance, and resistance to corrosion of salt mist, salinization, seawater and other chemical media, has the appearance and texture of resin artificial stones after polishment, also has the advantages of good decoration effect, no toxin, environmental protection and long service life, and can be widely applied to various interior and exterior decoration projects related to natural stones and resin artificial stones.

Description

technical field [0001] The invention relates to a novel inorganic artificial stone plate in the field of decorative building materials, in particular to a non-cement based inorganic artificial stone plate and a preparation method thereof. technical background [0002] Stone is a commonly used bulk decorative building material, which can be divided into natural stone and artificial stone. Natural stone has always been popular due to its special decorative effect and its wide application range. However, due to the problems of limited resources, large-scale paving, color difference and different degrees of radioactivity exceeding the standard, its full range is limited to a certain extent. Orientation development. Artificial stone has the advantages of adjustable color, no color difference in large-scale paving, use of leftovers mined from natural stone, and environmental protection. It has become the current development direction of the decorative stone industry. [0003] Ac...
