METHOD OF GLUING A WOOD PRODUCT AND A GLUED WOOD PRODUCT
20230219252 · 2023-07-13 · ·

The present invention relates to a method of producing a glued wood product for use in construction, comprising the steps of: providing at least two wooden pieces each piece comprising at least one joining face; creating a groove in at least one of said joining faces where the groove is arranged between a pair of peripheral edges; applying adhesive onto at least one of the joining faces of at least a first of said two wooden pieces; arranging said first wooden piece so that the joining face which comprises the applied adhesive meets a corresponding joining face of said second wooden piece, wherein at least one of said two joining faces comprises said groove; pressing the two joining faces towards each other so that the adhesive is compressed between said two wooden pieces, and maintaining said pressing for a sufficient time to bond the wooden pieces to each other; wherein the applied pressing force is strong enough to force the wood tissue to collapse at a contact area until the pressure force is transmitted primarily through the adhesive, wherein said contact area is defined by the surface area whereat the two joining faces of said wooden pieces contact each other upon being pressed together.

Adhesive compositions containing (1) one or two adhesive compositions produced from the fruit but not the seeds of Osage orange fruit and (2) a known adhesive. The one or two adhesive compositions produced from the fruit but not the seeds of Osage orange fruit are produced by a process involving drying the cut peel and mesocarp but not the seeds of the fruit of Osage orange to produce dried peel and mesocarp, milling the dried peel and mesocarp to produce milled peel and mesocarp, extracting the milled peel and mesocarp with an organic solvent (e.g., hexane) or a polar aprotic solvent (e.g., ethyl acetate) to produce the first adhesive composition, and optionally wherein the amorphous layer between the polar aprotic solvent and the milled peel and mesocarp is the second adhesive composition.

Disclosed is a composite floor, comprising a wear-resistant layer, a polyvinyl chloride patterned fabric layer, a base material layer, a balance layer, and a muting layer that are sequentially arranged, the wear-resistant layer being a melamine wear-resistant paper layer. The composite floor has a clear and vivid pattern, and the wear and scratch resistance is far better than that of a conventional floor, the manufacturing process comprising laying, hot pressing, demolding and tempering steps. The manufacturing process has simple steps, and the obtained composite floor has high dimensional stability and good wear and scratch resistance.

ADHESIVE COMPOSITION
20220017797 · 2022-01-20 · ·

An adhesive composition comprising a silane-modified epoxy resin, a dicyclopentadiene novolac epoxy resin and a curing agent. The composition shows good oily steel bonding, even in the absence of CTBN rubber or rubber adducts as toughening agents, with good Tg values of the cured resin and good Tg retention after hot wet aging.
