摘要:
The present invention provides marble chips produced by hardening resin composition containing binders and reactive monomers, wherein said binders contain halogenated alkoxylated diacrylate oligomers. The marble chips of the present invention can be formed into a uniform pattern, regardless of the time taken for hardening or molding. Therefore, an artificial marble using the marble chips of the present invention may have an outer appearance and texture the same as those of engineered stone, and also present theremoformability and workability characteristics which are advantages of an artificial acrylic marble.

The invention relates to a method for coating a stone substrate, a board made of stone material and a composition for coating said board, consisting of the formation of a layer over a stone substrate to increase its hardness, chemical resistance, wear and scratch resistance, comprising applying on the substrate a coating matrix incorporating an organic material and fillers including inorganic nanoparticles and/or microparticles; chemically binding said matrix to the substrate by a self-assembly process and/or a binding process by covalent bonding, electrostatic bonding, van der Waals bonding or hydrogen bonds; and finally drying said matrix. The mentioned organic material is selected from organosilanes, organophosphates, polycarboxylic compounds, compounds based on triazine heterocycles and said nanoparticles are nanoparticles of oxides, carbides, borides, nitrides of metals or of semimetals.

An engobe for working ceramic and earthenware articles constituted by marble dust, clay diluted in water and fine-grained sand and a method of application of an engobe onto a ceramic and earthenware wherein on an article a first engobe is applied, said engobed article is placed in a dryer where a first phase of desiccation takes place, the article is baked in a ceramics kiln at a temperature of between 900° C and 960° C, at the end of baking the article is placed in a covered area and dried to age the engobe for 60/80 days, for the natural and spontaneous falling away of the engobe.
摘要:
Method for consolidating slabs (11) of stone material by impregnation of the slab with hardenable fluid resin, comprising the steps of: providing a support tray (15); placing a slab (11) of stone material to be consolidated on said support tray (15); associating with the slab (11) a peripheral containing barrier (19; 19') impermeable to the fluid resin and adhering to the slab substantially without interruptions, so as to prevent the fluid resin from flowing outside said peripheral barrier; pouring the resin from the top onto the exposed face of the slab (11) inside the perimeter defined by said barrier (19; 19'), until the corresponding exposed face of the slab is completely covered; causing hardening of the resin.
摘要:
Agglomerated stone products consisting of powders and granules of marble or limestone in general, granite, quartz and silica or feldspathic sands mixed with resins, wherein nanometric particles of titanium dioxide are incorporated therein and process for their manufacture. Tiles and slabs for flooring, wall covering or work surface are able to interact with the surrounding environment by reducing the chemical and biological pollutants in the air and the bacteria with which the surfaces come into contact, because a photocatalytic preparation of nanometer-sized titanium dioxide is added to its composition.

摘要:
The method for preparing an artificial marble having a crack pattern is disclosed. The method includes preparing a first and a second polymeric compositions of different viscosities; pouring the first polymeric composition into a molding cell; pouring the second polymeric composition onto the first polymeric composition; inducing migration of the first polymeric composition to the upper part of the second polymeric composition due to the difference in viscosity between the first and the second compositions; and curing the two polymeric compositions to form a crack pattern, wherein the viscosity of the first polymeric composition is lower than that of the second polymeric composition.
