Production method for particle board and fiber board

摘要

Provided is a production method for particle boards or fiber boards which achieves production efficiency greater than that of conventional production methods. A production method for a particle board or a fiber board, comprising the step of adding polycarboxylic acid into a plant-derived product that has been segmented or formed into fibers, and further comprising the step of adding a small amount a compound having one or more types of an isocyanate group to the plant-derived product and/or the polycarboxylic acid.

1. A method for manufacturing particleboard or fiber board comprising a step of adding a polycarboxylic acid to plant-derived matter that has been turned into small pieces or fibers, further comprising a step of adding a small amount of one or two or more of an isocyanate group-containing compound to the plant-derived matter and/or polycarboxylic acid, wherein a weight ratio of the plant-derived matter to the isocyanate group-containing compound is 100:0.1 to 100:3.0, and wherein a weight ratio of the polycarboxylic acid to the isocyanate group-containing compound is 100:0.2 to 100:30.
