    摘要: A method of producing a surfaced composite panel of cellulosic particulates, such as wood flakes, involves the application of polymer forming foamable material to at least one of the first and second major surfaces of the panel, contacting said at least one of the first and second surfaces with a pressure applying surface to apply pressure thereto, foaming the polymer forming foamable material while pressure is applied and curing the applied foam material to produce a polymeric coating on the panel with the desired surface, which is typically extremely smooth. One or both surfaces may be surface treated in this manner. A skin formed on the surface of the panel is believed to add to the strength and stiffness of the coating on the panel. A wide variety of foaming systems may be used to accomplish this surface treating. By avoiding sanding the surface treated panel, the skin remains intact. The resulting panel, in addition to being extremely smooth as desired, resists water penetration when subjected to water or high humidity conditions. The resulting panel is receptive to adhesives for purposes of securing overlaying materials such as vinyl, reduces formaldehyde emissions when a panel formed of the resin which emits formaldehydes is surface treated.

    摘要: A rapid curing adhesive for wood finger jointing and laminating and a method of its use are disclosed. The adhesive consists of two parts that are used as a honeymoon system. One part is used on one side of the joint being formed and the other part on the other side. When the parts are joined under pressure a very rapid reaction occurs resulting in a durable weather resistant joint. Wood finger joints bonded with the adhesive can be handled for further processing within as little time as 15 seconds. The first part of the adhesive is a conventional resorcinol-formaldehyde or phenol-resorcinol formaldehyde resin containing a hardener such as an alkylene group donor. The second part is a similar resin lacking any hardener but containing a modifier which is a heterocyclic oxygen and nitrogen containing compound. Morpholine has proved to serve well as the modifier. The hardener in the first part is used in a sufficient amount to effect a thermosetting cure for the resin used in both parts. Despite the rapid reaction when the two parts are combined, the adhesive has a significant closed assembly time tolerance before application of full pressure to the joint.

    摘要: A process for making engineered lignocellulosic-based panels with superior strength and dimensional stability. The process comprising adding to green lignocellulosic particles a low-nitrogen content, high molecular weight, phenol-formaldehyde resin before the green particles are dried. The resin is added in an amount from about 1 to 25 weight percent based on the dry weight of the green lignocellulosic particles. The resin has a nitrogen content of from about 0 to 3%, a viscosity of from about 20 to 2000 cps at 20° C., and a molar ratio of formaldehyde/phenol of from about 1.2 to 3.0. The green lignocellulosic particles treated with the resin are dried until the particles have a moisture content of from 1 to 8%. A second resin is added to the dried particles and then the dried particles are consolidated under heat and pressure to form the engineered panel.
