A fire-retardant wood-based composite is formed by treating a green wood furnish with an amount of a phosphate/borate fire retardant treatment effective to increase the fire retardancy of the resulting wood-based composite, compared to the fire retardancy of the corresponding wood-based composite lacking the fire retardant. The fire retardant treated green wood furnish is blended with a binder and then bound, as by pressing the furnish, to form a non-leaching fire-retardant wood based composite. Another aspect of the invention is the product formed according to the preceding process. The fire retardant may also act as a catalyst to cure the binder and thus promote binding. Also, the addition of the fire retardant to green wood chips, without the need to dry them to a low moisture content, is believed to be novel.

Methods of incorporating phosphate/borate fire retardant formulations into wood based composite products

The specification describes preserved solid wood or wood composites including a copper ammonium acetate complex wood preservative and a drying oil. The wood preservative is present in the wood in an amount effective to improve the resistance of the treated wood to at least one type of decomposition, such as decay or insect attack. The drying oil is present in the wood in an effective amount to accomplish at least one useful end, such as reducing the water absorption or thickness swell of the treated wood or increasing its mechanical strength, even in a wood composite made using less binding resin than usual. Yet another aspect of the invention is a method of making the treated wood from green wood in solid or flaked form. A copper ammonium acetate complex wood preservative and optionally a drying oil are added to the green wood.

Reactive oil/copper preservative systems for wood products

A method of tempering composite fiber panels eliminates a need for a bake oven during the tempering step. Both the front and back surfaces of the panels are sprayed with a tempering oil including a mixture of a drying oil and a dryer or catalyst. The drying oil may include a linseed oil refined to minimize low molecular weight and a conjugated oil. Sometimes the drying oil is further mixed with either a conjugated oil, a catalyst, a low molecular weight isocyanate resin (Imw-MDI) or another additive. The sprayed panels are stacked preferably in face-to-face contact inside a curing chamber heated only by the residual heat in the hot panels. A number of additives to the tempering oil are considered. A number of different forms of commercial panels are considered, such as: hardboard, oriented strandboard, fiber board siding, wafer board, medium density fiber board, particle board, and other similar boards.

Method of tempering composite board panels without use of a bake oven

The invention provides an adhesive system comprising a blend of resin and a co-adhesive conjugated triglyceride drying oil acting as a internal release agent which is mixed with fibers for bonding composite panels such as oriented strand board, particle board, plywood, MDF, hardboard, and similar panels. The resin is a fast acting bonding material which forms a mat of fibers into a self sustaining panel within a time limit during which a press may be economically utilized. The triglyceride acts slower so that, after the panel is formed, there is enough time to penetrate the fibers to a depth that results in a superior bonding. The conjugated drying oil is a release agent that provides an internal release agent that prevents the composite panel from sticking to the press that bonds it.

Co-adhesive system for bonding wood, fibers, or agriculture based

Fiber-reinforced protein-based biocomposite particulate material containing a legume-based thermosetting resin and cellulosic material, and rigid biocomposite pressure-formed materials produced therefrom, are provided. The particulate material and resultant pressure-formed materials contain the legume-based resin and fibrous cellulosic material in amounts such that the ratio of cellulose solids to resin solids is about 0.8:1.0 to about 1.5:1.0. Particularly preferred pressure-formed materials also include a secondary thermosetting binder, such as an isocyanate.

Biocomposite material and method of making

The invention provides an adhesive system comprising a blend of resin and a co-adhesive conjugated triglyceride, which is especially well suited to bonding composite panels such as oriented strand board, particle board, plywood, MDF, hardboard, and similar panels. The resin is a fast acting bonding material which forms a mat of fibers into a self sustaining panel within a time limit during which a press may be economically utilized. The triglyceride acts slower so that, after the panel is formed, there is enough time to penetrate the fibers to a depth that results in a superior bonding.
