Technical Field

The invention relates to the technical field of artificial stones, in particular to a full-body pearly-luster artificial stone and a preparation method thereof.

Background

The artificial stone is a composite material with stone texture, which is processed by using resin, cement or other adhesive materials as a binder, using natural/waste stone crushed aggregates and other additives as main aggregates through the working procedures of bonding, stirring, mixing, vacuum pressing, vibration molding, condensation, solidification and the like. It has the advantages of no toxicity, no radioactivity, oil resistance, stain resistance, bacteria resistance, mildew resistance, wear resistance, impact resistance, easy maintenance and the like, and is widely applied to the decoration of indoor and outdoor floors, walls and table tops. The artificial stone not only has the incomparable advantages of natural stones such as various colors, fine textures, gorgeous patterns and the like, but also can simulate or even surpass the appearance of the natural stones in a manual intervention mode, so the artificial stone can gradually replace the natural stones.

At present, an acrylic pearlized panel is sold in the market and generally comprises a base material, a pearlized layer and an organic glass layer, wherein the pearlized effect is provided by a layer of uniformly distributed pearlized pigment, and the organic glass on the surface plays a role in light transmission and protection. Although the artificial stone has a certain pearly-luster effect, the artificial stone has strong plastic feeling, the organic glass on the surface of the artificial stone has low hardness and is not wear-resistant, the artificial stone is not easy to repair after scratching, and the artificial stone has poor stability of a multilayer structure, is easy to crack and has low market acceptance.
