Disclosed are an artificial marble composition having a natural marble texture, and a method for producing artificial marble using the same. The artificial marble composition according to the present invention comprises: a first resin mixture; and a second resin mixture which is added to the first resin mixture and has a viscosity different from the first resin mixture, wherein each of the first and second resin mixtures comprises a base resin and an inorganic filler, and wherein the second resin mixture further comprises a thixotropic agent.

A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

A molding machine for synthesizing a stone by means of beats of a heavy hammer includes a base, a heavy hammer mounted on the base, and a driving device for driving the heavy hammer. The base is provided with a material-load zone, and the heavy hammer is configured to beat the material-load zone. A processing method for synthesizing a stone by means of beats of a heavy hammer includes the following steps: burdening; material distribution; shaping; and solidification.

The invention relates to a moulded part of a composite material comprising a main body (10) of polymer concrete or of reaction resin, which has at least one adhesion bonding surface (11) for adhesively bonding to an article, wherein the adhesive bonding surface (11) is detachably connected to a laminate layer (12) texturing the adhesive bonding surface (11).

In a method for manufacturing articles in the form of a slab or block, the articles are obtained from an initial mix comprising aggregates and a binder. Synthetic aggregates and fillers have a hardness greater than or equal to 5 Mohs, and contain silicon dioxide substantially only in amorphous form, the silicon dioxide in crystalline form being present in quantities of less than 1% by weight.

The present invention involves a multiplayer artificial stone and its preparation method. The decorative layer comprises the following components in percentage by weight: 80%-90% of a decorative stone, 5%-15% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1%-5% of a pigment filler. The bottom layer comprises the following components in percentage by weight: 65%-78% of a calcium carbonate stone, 10%-18% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1-15% of a pigment filler. The preparation method involves preparing the decorative layer and the bottom layer separately and then binding the two layers together by pressing. This arrangement allows the multilayer artificial stone to have good decorative effect and product quality; in addition, each layer contains only one type of stone, therefore its preparation is easier and can be more precisely controlled, lowering production cost.

A method for manufacturing an engineered stone comprising the steps of: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and printing a printed pattern on at least a top surface of the engineered stone.

A method of forming a polymer concrete CNG tank by forming an inflatable liner member composed of high density polymer impermeable to CNG; providing column forms as part of the liner member, the column forms having open tops and open bottoms and extending completely through the liner member; providing an outer form; positioning the liner member within the outer form with the column forms vertically oriented, the liner member being positioned to provide a gap between the liner member and the outer form; inflating the liner member; pouring polymer concrete about the liner member and through the column forms; and allowing the polymer concrete to cure. Reinforcement members may be positioned around the liner member and within the column forms prior to the step of pouring the polymer concrete.

A process for the production of an article for the cladding of floors or walls, comprising the steps of, in a mold: a) optionally applying a gel coat layer, based on a first curing polymer resin, on the inside of the mold in order to obtain a coated mold, and b) introducing into the core of the mold or into the core of the coated mold from step a) a filling composition which is based on a second curing polymer resin supplemented with at least one mineral filler, wherein core contains at least 5% wt and at most 20% wt of curing polymer resin, relative to the dry amount of filling composition, and the filling composition contains only one single initiator in a concentration of 0.5% wt to 5.0% wt relative to the amount of curing polymer resin in the filling composition.

A process (method, system, etc.) for the manufacturing of slabs made of resin-bonded mineral grits comprises at least the phases of: supply of at least one mixture made of mineral grits and resins; compaction of the mineral grits and resins to obtain a compacted slab; hardening of the compacted slab to obtain a finished slab provided with at least one exposed surface and having an intrinsic degree of porosity; decoration with ink by digital printing of the exposed surface according to at least one predefined design; and, prior to the decoration and subsequently to the hardening, at least one phase of increase in the intrinsic degree of porosity of the finished slab, adapted to promote the penetration of the ink in the finished slab.
