Study on fire retardant treated wood.

Part2. Evaluation of adhesive properties.

Abstract

Adhesion is used flequently when we joint laminas to manufacture laminated woods. But in the case of adhering non fire retardant toreated wood, there is a problem of lowering the adhesive properties.　Therefore, we evaluate the influence by two factors to the adhesive properties when using a Phenol-Resorcinol　Adhesive. One factor is combination of tree species, and the other is surface treatment method. The results show that adhesive properties are strongly affected by tree species, and treating certain type of primer onto the nonconbustible wood enhances the adhesive properties.
