摘要:
The present invention relates to an aqueous phenol-formaldehyde resole resin prepared by reacting phenol and formaldehyde in the presence of a source of calcium ions, to a curable powdered (particulate) resole resin made by spray drying the aqueous phenol-formaldehyde resole resin, to a method of preparing a wood composite using the curable, powdered resin, and the related wood composite bonded with the curable, powdered resin.

Fiberglass products and methods for making same are provided. The fiberglass product can include a plurality of fibers and a two phase binder composition comprising a mixture of an aqueous polymer and a powdered polymer.
摘要:
The invention comprises an aqueous phenol-formaldehyde resole resin liquid fortified with powdered (e.g., spray dried) phenol-formaldehyde resole resin, preparing wood composites, particularly oriented strand board (OSB), waferboard, particleboard, medium density fiber board, and hardboard, using the solids-fortified liquid resin, and related wood composites bonded with the solids-fortified resin.
摘要:
The present invention relates to a method for preparing a wood composite, and the related wood composite itself formed by steam injection pressing using a phenol-formaldehyde resin binder composition capable of rapidly curing in a saturated or superheated steam atmosphere.
