The phosphorescent chip (II) includes about 8 wt % to about 15 wt % of an unsaturated polyester resin (A), about 85 wt % to about 92 wt % of a silica-containing compound (B) based on a total amount of the unsaturated polyester resin (A) and the silica-containing compound (B) of the phosphorescent chip (II), and further includes about 2 parts by weight to about 10 parts by weight of a phosphorescent pigment (D) based on about 100 parts by weight of the unsaturated polyester resin (A). The silica-containing compound (B) includes about 20 wt % to about 30 wt % of a silica powder (b1) based on a total amount of the phosphorescent chip (II).

A self-cleaning composite material including the following composition: 50%-85% in weight of alumina trihydrate (ATH)-based mineral charges; 10%-30% of cross-linking polymer comprising polyester resin; photocatalytic Titanium Dioxide (TiO2) dispersed in the cross-linking polymer in a weight percentage from 0.05% to 5% with respect to the weight of the cross-linking polymer; compatibilizing agent for anchoring between the photocatalytic TiO2 and the cross-linking polymer, wherein the anchoring compatibilizing agent of the TiO2 is silane; and cross-linking monomers in order to obtain the reticulation of the cross-linking polymer by thermal or chemical polymerization.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.

Composites made of a cross-linked acrylic polymer and an inorganic aggregate and/or mineral, with the cross-linked acrylic polymer being present at a concentration of 5% to 17%, by weight, are disclosed. Processes of preparing the composites are also disclosed.

Disclosed are a functional Ecostone and a method for manufacturing the same, wherein the functional Ecostone is characterized in that, on the basis of 100 parts by weight of a raw material formed by mixing 30-60 wt % of gypsum, 20-40 wt % of calcium carbonate, and 10-30 wt % of water, 1-30 parts by weight of a rose geranium extract, 2-10 parts by weight of basalt fibers, 2-10 parts by weight of mulberry fibers, 1-30 parts by weight of phytoncide, 1-30 parts by weight of ocher, and 1-30 parts by weight of charcoal are mixed.

A system and method for installing tile includes the use of fasteners and washers that are installed into the interstitial gaps of the tiles or installed through the face of the tile. The washers and fasteners create a downward pressure on the tiles to align the edges of the tiles and to ensure that the tiles conform to the surface to which they are applied, thereby significantly reducing or minimizing the occurrence of gaps or voids between the installation surface and the tiles. Once the tiles are fixed in position and the adhesive has set or cured, the washers and fasteners are removed and the interstitial spaces or gaps between the tiles is grouted and the tile can be painted or stained. Additionally, the method of manufacturing decorative concrete tiles uses flexible rubber molds to achieve a variety of unique shapes, patterns, and textures.

Artificial stone having excellent mechanical and weatherability properties is prepared from a highly filled crosslinkable organosilicon composition where the filler comprises at least 20 weight percent of coarse fillers, the organosilicon component contains silicon-bonded alkoxy and or hydroxyl groups, with a catalyst containing a metal compound and an amidine or guanidine.

A composite material includes, in an exemplary embodiment a polyurethane foam and a plurality of inorganic particles dispersed therein. The polyurethane foam is formed from a reaction mixture that includes a first polyether polyol having a first molecular weight and a functionality of about 3 or less, a second polyether polyol having a second molecular weight less than the first molecular weight and a functionality of greater than about 3, and at least one isocyanate. The ratio of an amount of the first polyol in the reaction mixture to an amount of the second polyol in the reaction mixture is between about 1:1 to about 5:1.
