US Patent:

56267053, May 6, 1997
Filed:

Jun 7, 1995
Appl. No.:

8/482512
Inventors:

Jack G. Winterowd - Puyallup WA
Harvey H. Cox - Seattle WA
Roland E. Kreibich - Auburn WA
Stanley L. Floyd - Enumclaw WA
Hans Gross - Auburn WA
Assignee:

Weyerhaeuser Company - Federal Way WA
International Classification:

B29C 6500
US Classification:

1563045
Abstract:

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.

Filed:

Dec 16, 1994
Appl. No.:

8/357378
Inventors:

Jack G. Winterowd - Seattle WA

Assignee:

Weyerhaeuser Company - Tacoma WA
International Classification:

B29C 4406
B29C 4412
US Classification:

264 455
Abstract:

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.

International Classification:

C07C 3720
C08G 1402
US Classification:

528129
Abstract:

A process for preparing phenol-formaldehyde novolak resins and molding compositions in which portions of the phenol normally contained in said resins are replaced by a phenol/neutral fractions extract obtained from fractionating fast-pyrolysis oils. The fractionation consists of a neutralization stage which can be carried out with aqueous solutions of bases or appropriate bases in the dry state, followed by solvent extraction with an organic solvent having at least a moderate solubility parameter and good hydrogen bonding capacity. Phenolic compounds-containing/neutral fractions extracts obtained by fractionating fast-pyrolysis oils from a lignocellulosic material, is such that the oil is initially in the pH range of 2-4, being neutralized with an aqueous bicarbonate base, and extracted into a solvent having a solubility parameter of approximately 8. 4-9. 11 [cal/cm. sup. 3 ]. sup. 1/2 with polar components in the 1. 8-3.
