  • Patent number: 10858554
    Abstract: Most processes currently being proposed and/or used for the production of lignin from kraft or soda black liquors are capable of producing two main types of lignin: high residual content (HRC) lignin and low residual content (LRC) lignin. Surprisingly, it was discovered that HRC lignin, is a suitable ingredient in alkaline adhesives, particularly wood adhesives of the phenolic type (e.g. resole resins). This biomaterial is environmentally green and remarkably low cost, which makes it an industrially viable material to be used as a novel and major ingredient in phenolic adhesives for the manufacture of exterior grade plywood, laminated veneer lumber, oriented strand board (OSB) and other wood products—this was successfully demonstrated in a number of laboratory experiments as well as several different mill trials. The composition, preparation and application of such wood adhesives are hereby disclosed.

    Abstract: The invention relates to a method of manufacturing a heat storage material that contains heat storage capsules. The heat storage capsules include a phase change material that absorbs and/or discharges latent heat in response to a change in temperature. The phase change material resides within outer shells of the heat storage capsules. The method involves binding abutting peripheral portions of a plurality of heat storage capsules with a molding binder, so as to form an intermediate granular molded heat storage material. An outer peripheral surface portion of the granular molded heat storage material is coated with a coating binder. The coated granular molded heat storage material is then subjected to a treatment that causes the coating binder of the coating layer to polymerize. The invention also relates to heat storage adsorbent materials, and articles (e.g., canisters) that include such heat storage adsorbent materials.

  • Patent number: 6464813
    Abstract: A laminating and coating system is employed with a gravure or flexographic set up using an enclosed doctor blade system with recirculation to coat adhesive onto a film and then laminate it to another film. The preferred adhesive is a two-stage epoxy consisting of a zero VOC 100% solids laminating adhesive having a mixed viscosity of 200-400 cps with the viscosity remaining within a desired range of 50-110 degrees F for up to 3 hours that will cure at ambient temperature. The adhesive is solventless and is unaffected by moisture. The adhesive consists of ingredients which make it permissible for use as an adhesive for laminations of films designed for food packaging pursuant to F.D.A. Regulation 175.105.

  • Patent number: 6461469
    Abstract: A finished product from lignocellulose, such as a length of wood or chipboard, is impregnated with a composition containing a thermosetting resin in a nonaqueous solvent, and a styrene polymer in a nonaqueous solvent. Excess impregnating composition is removed from the impregrnated material. The solvent or solvents are also removed. The thermosetting resin may thereafter be subjected to temperature conditions for polymerization to form a finished product.

  • Patent number: 6440255
    Abstract: A process is provided for producing fast curing bonded with phenolic resin, which comprises pulverulent phenolic resins mixed with or applied to the substrate to be adhered together with pulverulent addition polymers selected from the group consisting of polyvinyl alcohols and addition polymers, stabilized by hydroxyl-containing protective colloids of at least one monomer selected from the group consisting of the vinyl esters of branched or unbranched carboxylic acids of 1 to 12 carbon atoms, the esters of acrylic acid and methacrylic acid with branched or unbranched alcohols of 1 to 12 carbon atoms, vinylaromatics, vinyl halides, olefins and dienes, and subsequently, by the employment of elevated temperature and optionally elevated pressure, cured and processed into a shaped article.

  • Publication number: 20020114968
    Abstract: The disclosed invention is a dimensionally stable laminate prepared by layering resin saturable sheets, treating the layered sheets with a polymeric resin, pressing the treated layered sheets together under high pressure and high temperature to form a laminate and then subjecting the newly manufactured laminate to high humidity (greater than 65%) at relatively low temperatures (32°-45° C.) before exposure to ambient conditions.

  • Patent number: 6432254
    Abstract: A method for making a consolidated wood product comprising coating wood components with a B-stageable, phenol-formaldehyde resole resin; heating the coated wood components to about 80 to 140° C. for a time sufficient to advance the resin to a B-stage; forming a mat or stack of the wood components coated with the B-stage resin; exposing the mat or stack of coated wood components to a saturated or superheated steam atmosphere in a hot press; and compressing the layup to form the consolidated wood product. The phenol-formaldehyde resole resin used in the method has a number average molecular weight of between about 200 and 600, has a F:P mole ratio of about 1.3:1 to 2.0:1, and has been modified with 0 to about 5.5 wt % of caustic based on resin solids.

  • Patent number: 6402869
    Abstract: The invention relates to a method of gluing veneers to form LVL and plywood boards from veneers laid one over the other in several layers by curing the adhesive placed between the single layers in a heated press. The invention consists in the fact that the gluing and pressing of the outer layers of a veneer pack to form LVL and plywood boards is performed by high-temperature adhesive and the inner layers by low-temperature adhesive, so that the amount of heat to be put into the veneer pack decreases from the outside in.

  • Publication number: 20010051247
    Abstract: A flame retardant article produced by forming a thermoplastic material around at least a portion of a core of partially cured phenolic resin is disclosed. The article has reduced flammability and improved dimensional stability when exposed to flame compared to an article consisting solely of the thermoplastic material. By positioning the thermoplastic between the core and at least all surfaces of the article which may become directly exposed to fire or heat when the article is in use, it is possible to impart the flexibility, colorability and impact resistance characteristics of thermoplastic materials to the article. At the same time, the inner core of the phenolic resin reduces the flammability and improves the dimensional stability of the article when the article is exposed to flame.

  • Patent number: 6306241
    Abstract: There is provided a method for producing lignocellulosic composites. This method is useful in reducing the thickness swell of these composites on their exposure to water. This method also is useful in reducing the hot-press times required to make lignocellulosic composites. Furthermore, there is provided a method by which wax sizing may be used without the previously expected reduction in physical properties. Also, there is provided a method by which caul plate sticking may be reduced when hydrogen peroxide is used as a furnish add-on.

  • Patent number: 6132549
    Abstract: Discloses compositions of urea dissolved in aqueous, polymerizable phenolic resole resins, wood-product laminated composite products produced with such resins, with or without the urea, and methods for the production of wood-product laminated composites with such resins. The resins contain the alkaline polymerization product of (a) formaldehyde polymerized with phenol and aliphatic hydrocarbylphenol or (b) aliphatic hydrocarbylphenol dissolved in the resin containing the polymerization product of phenol and formaldehyde, wherein the hydrocarbylphenol has from 9 to 17 carbon atoms in the hydrocarbyl group and the quantity of hydrocarbylphenol is from about 0.2% to 5% based on the weight of the aqueous resole resin. Wood-product laminate composites bound with the above resole resin, after curing, exhibit unexpectedly low water absorption, good internal bond strength and reduced thickness swell properties.
