  • Patent number: 11685692
    Abstract: The present invention relates to a composition for manufacturing artificial marble including a first preliminary composition and a second preliminary composition which include an acrylic-based monomer, an acrylic-based resin, a polymerization initiator, a crosslinking agent, a coloring agent, and a gelling agent and have a viscosity of 100,000 Ps to 5,000,000 Ps and/or a storage modulus of 100,000 Pa to 1,000,000 Pa. A viscosity of the second preliminary composition is higher than a viscosity of the first preliminary composition. Coloring agents of the first preliminary composition and the second preliminary composition have different colors. A weight ratio of the first preliminary composition to the second preliminary composition is in a range of 1:1 to 500:1.

  • Patent number: 11254805
    Abstract: Described herein is flooring formed of an eco-friendly material, where the flooring has excellent heat resistance, durability, abrasion resistance and dimensional stability, and is formed of a non-PVC material and thus is recyclable via an extrusion processing at the time of disposal after use. Specifically, eco-friendly flooring is described in which a coating layer, an overlayer having ionomers, a printing layer, at least one middle layer, and at least one underlayer are laminated in order, where the overlayer of the flooring has ionomers, at least one of the middle layer and the underlayer has a thermoplastic polyolefin-based resin, a styrene-based resin, oil, and a filler, the thermoplastic polyolefin-based resin is contained in an amount of 50 to 150 parts by weight with respect to 100 parts by weight of the styrene-based resin, and the styrene-based resin may contain 25 to 45% styrene.

  • Publication number: 20190217582
    Abstract: A heat radiation sheet includes a low-hardness insulating heat-radiation layer and a high-heat-radiation insulating layer. Each of the low-hardness insulating heat-radiation layer and the high-heat-radiation insulating layer is formed by mixing a thermoplastic elastomer (TPE), a thermally conductive filler, a flame retardant additive, a process oil, and an additive. A method of manufacturing a heat radiation sheet having a double-layered insulating structure, includes: a first step of forming a mixture by mixing a thermoplastic elastomer (TPE), a thermally conductive filler, a flame retardant additive, a process oil, and an additive; a second step of melt-extruding the mixture at a temperature of 120 ? to 300 ? by a melt extrusion apparatus to from a melt extrudate; a third step of cutting the melt extrudate into a pellet form; and a fourth step of sheeting through melt-extruding the pellet into a sheet form by a melt extrusion apparatus.
