Description

Technical Field

[0001] The invention relates to an artificial stone, in particular to an artificial stone with a 3D texture effect and a preparation method thereof. Background Art

[0002] Stone materials used as decorative materials are generally divided into natural stone and artificial stone. Natural stone, such as marble, also known as marble, has beautiful textures and bright colors, and is widely used in building interior walls. The radioactive element content of natural marble often exceeds the standard, which will cause harm to the human body, but artificial stone does not have this problem; natural marble is easy to break and difficult to process, while artificial stone uses resin with high elongation at break and good toughness (such as acrylic resin) as the base material, which is easy to process and not easy to break. At present, artificial stone has been widely used in living rooms, conference rooms, offices, lounges and bathrooms in many places such as civil aviation airports, banks, hotels, hotels, companies, office buildings, etc. It is also widely used in home decoration, such as artificial stone countertops, kitchen cabinets, sanitary ware and other fields.

[0003] The representative varieties of Chinese artificial stone solid surface patterned plates include netted stone, phoenix tail stone, wood grain stone, multi-color artificial textured stone, etc. Most of its production processes are: pouring the mixed slurries of various colors into the mold in sequence or at one time with the help of equipment, and then pushing them into the vacuum box to evacuate, and then curing and forming them after leaving the box. The artificial stone patterned plates produced by the above process have the disadvantages of low simulation degree and insufficient three-dimensional texture, which leads to the current artificial stone not having a good 3D texture effect and concave and convex texture, which can bring consumers a good sense of reality and comfort in experience in use.
