  • Patent number: 8951634
    Abstract: The present invention relates to a filler material for a floor, comprising a natural base material and a mixture containing loess and a resin in powder or pellet form, as well as to a method for producing the filler material. The filler material of the present invention uses the natural base material and is thus environmentally-friendly and not harmful to the human body. Further, in the event rice husks are used as the natural base material, a person slipping on the floor is protected from burning caused by friction as the rice husks have a high moisture content. In addition, the loess contained in the filler material keeps the floor from becoming moldy and emits far infrared radiation, and therefore is beneficial to the human body. The resin emulsion of the filler material prevents the natural base material from generating dust, thus preventing dust from entering the human body via the respiratory organs of the human body.

  • Publication number: 20140141239
    Abstract: Provided herein are multi-layered structures comprising coated substrates, and methods for producing the layered structures provided. Coatings according to the disclosure are provided in greatly reduced time frames as compared to coatings of the prior art. Coating structures as provided herein can be applied to a substrate such as a garage floor, a truck bed, railcar, seatainer, tractor-trailers and the like within a single day, and are sufficiently cured to withstand heavy traffic such as motorized vehicle traffic in as little as two hours after application of the polymer precursor layer material employed.

  • Patent number: 8722198
    Abstract: The present invention is directed to wood preservative compositions, methods of treating wood, and wood that has been treated with the preservative, which includes injectable particles comprising one or more sparingly soluble copper salts. The copper-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Exemplary particles contain for example copper hydroxide, basic copper carbonate, copper carbonate, basic copper sulfates including particularly tribasic copper sulfate, basic copper nitrates, copper oxychlorides, copper borates, basic copper borates, and mixtures thereof. The particles typically have a size distribution in which at least 50% of particles have a diameter smaller than 0.25 ?m, 0.2 ?m, or 0.15 ?m. At least about 20% and even more than 75% of the weight of the particles may be composed of the substantially crystalline copper salt.

  • Publication number: 20140113155
    Abstract: Disclosed is a window profile provided with a skin layer which a co-extrusion resin composition is dual-extruded on one surface of a profile extruded from a main extruder, wherein the co-extrusion resin composition contains wood fiber. The co-extrusion resin composition comprises a first raw material for forming a base color, a second raw material for forming a mid-tone color, and a third raw material for forming a high-tone color. According to the present invention as described above, the skin layer is integrally formed with one side of the profile by the co-extrusion, and thus it is possible to provide the texture of natural wood and thus a luxurious atmosphere. Further, in the window profile, various colors can be naturally expressed on the skin layer of the window profile so as to be distinguished from each other, the embo-patterns are formed into two steps, the repetition period of the patterns becomes long and the like, and thus it is possible to provide the graphicness similar to natural wood.
