Abstract
PURPOSE: To provide a particle board which is useful for a structure material having a water-proof and less bulging caused by suctioned water by a method wherein as a binding agent is used a phenol resorcin cocondensation resin which a part of phenol is replaced with resocin and sulfomethylene.
CONSTITUTION: In a method for manufacturing a particle board in which wooden chips are combined with each other by a binder agent, mol ratio of the phenol and the resocin is set at a range of 1.95:0.05W0.5:0.5, a combined formaldehyde has 0.75W1.5mol for a total 1 mol of the phenol and resorcin, 2W15% of the combined formaldehyde is sulfomethyle radical. As a binder agent is used a phenol resorcin cocondensation resin which is soluble in the water even if alkali having a value of pH of substanttially a range of 7.0W9.0 is not existed. The produced particle board has a superior water-proof and weather-proof characteristic and at the same time has a less bulging caused by a water absorption and moisture absorption.
