Determination of the influence of some boric acid added adhesives on combustion properties of beech wood
Abstract
Wood is a material that is always sympathized by human beings due to its naturality and used for very different
purposes in many areas. In this study, beech wood samples were prepared according to ASTM-E-69 and TS 3891
standards and laminated with boric acid added phenol-formaldehyde, urea formaldehyde and PVAc adhesives. Then,
the combustion properties of wood material that was obtained from lamination were researched.
For the combustion test, the air dried (12 %) samples were prepared in size of 4,5x19x1016 mm and then
laminated. For that purpose, 5% solution of boric acid was added in the rate of 5% to phenol-formaldehyde, urea
formaldehyde and PVAc adhesives. Combustion value was determined according to ASTM-E 69.
In combustion case, it is determined that boric acid has a fire retardant efficacy. Bonding strength samples were
prepared in size of 5x18x150mm. Then, gluing process was carried out.
