  • Publication number: 20110287263
    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.

The composites are further advantageously protected against weathering and color formation by the incorporation therein of at least one light stabilizer and at least one compound selected from the group consisting of the oxides, hydroxides or silicates of Ca, Mg, Al and Zn. The light stabilizers are selected from the group consisting of the ultraviolet light absorbers and the sterically hindered amines. The metal oxide is for example CaO. The natural products are for example wood flour, flax, hemp, jute, kenaf, or rice husk. The thermoplastic resin is for example polyethylene or polypropylene. The antifungal agent and potential coadditives are incorporated via melt processing such as extrusion, co-kneading, pultrusion and injection molding.

  • Patent number: 6942829
    Abstract: The present invention provides a method of forming a polymer-wood composite structure and additive systems for use therein. The method of the invention includes extruding a heated mixture that includes from about 20% to about 80% by weight of a thermoplastic polymer, from about 20% to about 80% by weight of a cellulosic filler material, and from about 0.1% to about 10% by weight of an additive system. The additive system according the invention includes a blend of from about 10% to about 90% by weight of a nonionic compatibilizer having an HLB value of from about 9 to about 19 and from about 10% to about 90% by weight of a lubricant. Use of the method and additive system according to the invention facilitates the production of highly filled polymer-wood composite structures at a very high output rate while maintaining commercially acceptable surface appearance.

  • Patent number: 6869989
    Abstract: Disclosed is a process for modifying cashew nut shell liquid (CNSL) which involves the steps of subjecting the CNSL to ozonolysis to form ozonolysis reaction products, followed by reduction of the ozonolysis reaction products to give a mixture of phenolic components and aldehydes. In a preferred embodiment, the process involves reacting CNSL with ozone to form a mixture containing ozonolysis reaction products, and then treating the mixture under reducing conditions to form a further mixture containing phenolic components with an eight carbon chain having a terminal —CHO group and alkyl components of varying lengths with either one or two terminal —CHO groups. The resulting CNSL aldehydes may be used to form adhesives for use in the manufacture of composites such as wood particle board.

  • Patent number: 6787245
    Abstract: Sulfonated aliphatic-aromatic copolyesters are provided. The copolyesters are produced from a mixture of aromatic dicarboxylic acids, aliphatic dicarboxylic acids, ethylene glycol, other glycols, and components containing alkali metal or alkaline earth metal sulfo groups, such as a metal 5-sulfoisophthalic acid derivative. The copolyesters have lower sulfonation than known sulfonated polyesters, and provide advantageous thermal properties for some end uses. The sulfonated aliphatic-aromatic copolyesters are useful in forming coatings or films on various substrates, and in packaging. Some compositions comprising the sulfonated aliphatic-aromatic copolyesters are biodegradable, as are some of the sulfonated aromatic-aromatic copolyesters.
