Composite wood particulate products with aldehyde-free adhesives and method for making same |
摘要 |
The disclosed composite wood particulate products, adhesives contained in such wood particulate products, and methods of making the adhesive and the wood particulate products employ an aldehyde-free adhesive, and more specifically a formaldehyde-free adhesive. The aldehyde-free adhesive includes an inert additive that extends a resin, such as an isocyanate resin, and forms an evenly dispersed, less expensive polymeric adhesive admixture. The extender-filler of the resin is mixed with water to form a slurry. The slurry can then be mixed with a resin, like the isocyanate resin, to form the adhesive. Various rheology modifiers can be added, if desired, to the extender-filler or the slurry. The adhesive can be blended with wood particles to form a mat that is then pressed into a composite wood particulate product. |

1. A method of producing an adhesive system for use in manufacturing composite wood products comprising:
introducing water to a mixing container; introducing an interactive extender-filler material that has been subjected to a controlled aging process for a time period of about 3 weeks to about 8 weeks to the mixing container; mixing the aged interactive extender-filler material with the water to form a slurry; and mixing the slurry with an aldehyde-free isocyanate adhesive to form the adhesive system. |
