Random Variegated Coloring During Molding Patents (Class 264/73)
  • Patent number: 9174358
    Abstract: During the manufacture of slabs with a veined effect a liquid or powder coloring agent is deposited on the surface of a thin layer of starting mixture by means of at least one dispensing device (40) and the resultant mixture is supplied, falling freely, from one end of an extractor belt (30) forming the bottom of a mixture metering/distributor unit, following which the mixture is transferred, falling freely, onto a temporary molding support (14). This results in the production of slabs provided with veining extending through the entire thickness of the slabs and also visible along the whole edge of the slab, even after it has been machined.

  • Patent number: 9017585
    Abstract: A method for decorating a composite placed in a mold in a resin transfer molding process includes selectively depositing unbonded pigments on one or more areas of a preform of the composite, and injecting a resin into the mold via one or more resin input ports operably connected to the mold. The injected resin carries the selectively deposited unbonded pigments on a path on one or more areas of the preform of the composite along a direction of flow of the injected resin, thereby creating ornamental pigment flow patterns in the composite for decorating the composite. The method also creates bands of ornamental pigment flow patterns by depositing the unbonded pigments on a transfer medium positioned on the composite, positioning the transfer medium in proximity to the resin input ports, and selectively injecting the resin onto the transfer medium deposited with the unbonded pigments, via the resin input ports.

  • Patent number: 8980149
    Abstract: The present invention relates to a method and device for manufacturing artificial stone. More specifically, the method includes the steps of: (a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material for artificial stone mixed with the chips into a mold; (c) applying primary vibration using a vibration device such that the raw material is uniformly dispersed in the mold; (d) applying vacuum to eliminate bubbles in the raw material; and (e) molding artificial stone by applying a secondary vibration using the vibration device. According to the method and device for manufacturing artificial stone of the present invention, the deposition rate of chips exposed at a surface of artificial stone is maximized, and thus the external appearance of artificial stone can be more naturally expressed and resistance against abrasion and staining can be improved.

    Abstract: The invention provides novel marble-like composite materials and methods for preparation thereof. The marble-like composite materials can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production. The precursor materials include calcium silicate and calcium carbonate rich materials, for example, wollastonite and limestone. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as pigments (e.g., black iron oxide, cobalt oxide and chromium oxide) and minerals (e.g., quartz, mica and feldspar). These marble-like composite materials exhibit veins, swirls and/or waves unique to marble as well as display compressive strength, flexural strength and water absorption similar to that of marble.

  • Patent number: 6910796
    Abstract: A process and equipment for producing multi-color concrete products, including architectural concrete blocks, concrete bricks, modular concrete products that are suitable for use in landscaping applications, such as retaining wall blocks, concrete pavers, and concrete slabs. The invention includes a spray mechanism that sprays liquid pigment onto concrete discharged from a hopper. The concrete then proceeds to a blending mechanism which blends the pigment into the concrete to produce a multi-color concrete blend. The concrete blend is then used to produce multi-colored concrete products.

  • Patent number: 6815042
    Abstract: A floor covering made up of at least two layers bonded to one another, including a bottom layer (2) of electrically conductive rubber arranged under a light-colored top layer (1) of rubber, where the top layer (1) is interrupted in partial areas distributed over its area in a pattern, and formed by electrically conductive rubber there. The top layer (1) is produced from a powder (1.1) of first particles (1.2) that are light in color and made of electrically insulating rubber, as well as second particles (1.3) embedded in it, which are made of electrically conductive, at least partially vulcanized rubber. The second particles (1.3) have a diameter D, determined by screen analysis, that is at least as great as the thickness D1 of the top layer and, for practical purposes, not greater than the total of the thicknesses of the top layer and the bottom layer D2. The first (1.2) and the second (1.3) particles are pressed together and to the bottom layer (2), without pores, and bonded by vulcanization.

  • Patent number: 6790393
    Abstract: An article and method of preparing a synthetic solid surface material having a simulated burled wood effect in a pattern formed by preparing a resin matrix with iron oxide pigments and pearlescent mica pigments, adding a darker mica pearlescent pigment and/or an iron oxide pigment composition with a slightly less specific gravity than the matrix for the creation of a burling effect, pouring into a flat substrate in paths, and applying vibration or agitation which generally allows or speeds the darker pigment to rise and bubble to create a burling effect on the back side of the solid surface. The back side of the slab, the surface generally not in contact with the mold, is then sanded to the desired thickness on a wide belt sander.

    Abstract: A process for the production of a manufactured article for coatings, for components of sanitary ware, kitchen fittings, etc., in polymerized transparent resin in which marble and other stones are embedded. The surface of the product is worked by brushing with abrasives, so as to obtain depressions corresponding to the resin, and slight projections with substantially uniform distribution corresponding to the inserts; advantageously, the inserts are “decapitated” to give smoothed surfaces.
