The biological resistance and fire endurance are important to the particle board for interior and furniture materials. To obtain basic informations concerning those properties. we manufactured boards of treated particles with boron compound as wood preservatives and investigated effects of boron compounds on the mechanical and physical properties of particle board. The results were as follows ‘ 1. The optimum borax treatment was approximately 0.1 % for oven dried weight of particles. Treatment wi th O. 1 % content of borax showed increased internal bond strength of 117% and increased bending strength of 76% ‘ 2. When treated with borax and boric acid. bending strength of board showed about 25% increase at the mixture ratio of borax and boric acid of 3 to 7. However. the effects of bonding was poor than those of sole borax 3. The treatment of boron compound had not effects on dimensional stability of board. Addition of paraffin wax emulsion is necessary to manufacture of the board. 4. The treatment of boron compound can be expected for the manufacture of special particle board wih biological resistance. fire endurance and good bonding properties.
