Various isocyanate and polyurethane adhesives were used in the experiment. The effects of adhesive composition and sizing amount on the particleboard material were investigated. The results showed that the isocyanate structure, the isocyanate content (NCO), and the structure of the polyol were all stable to the size of the particleboard. Sex has an effect. When the amount of sizing is 8%, in order to obtain good sheet properties, the NCO content in the adhesive must be above 10%. The performance of the board increases as the NCO content increases. For the same NCO content conditions, the use of an adhesive incorporating a polyol in an isocyanate provides better particleboard performance than a simple isocyanate adhesive.
