Boron addition to non- or low-formaldehyde cross-linking reagents to enhance biological resistance and dimensional stability of wood

New alternatives for wood preservation based on thermal and chemical modification of wood— a review

“…Boric acid and phenylboronic acid have been added into aqueous solutions of DMDHEU to improve wood durability (Yalinkilic et al 1999). DMDHEU reduced boron leachability, while boron appeared to decrease cross-linking efficacy of DMDHEU.…”

Some Physical and Mechanical Properties of Borate-Treated Oriental Beech Wood

“…Most existing fi re retardants are effective in reducing different fi re parameters of wood such as ignitability, heat release, and fl ame spread. In recent years, there has been a rapid increase in the application of chemicals to wooden materials in order to improve their physical, mechanical, biological, and fi re properties (Brelid et al, 2000;Chao and Lee, 2003;Su, 1997;Yalinkilic et al, 1999). Borates have several advantages as wood preservative in addition to imparting fl ame retardancy, providing suffi cient protection against wood destroying organisms and low volatility.…”

Wood Property Improvement of Siberian Pine by Combination of Boric Acid Impregnation and In-Situ Polymerization of Ԑ-Caprolactone

“…Boron compounds as a wood protection agent are known to be an active fire retardant and effective against both insect and fungi attacks [3]. Effects of boron compounds on mechanical, biological and dimensional stability of wood and wood products have already been investigated in detail [4]. In addition, it is well known that boron compounds can be leached out when used for outdoor purposes, thus wood products become vulnerable to biological organisms [5].…”

“…In addition, it is well known that boron compounds can be leached out when used for outdoor purposes, thus wood products become vulnerable to biological organisms [5]. To overcome this problem researchers have studied to keep boron compounds into the wood cell wall and tried to fix it inside [4][5][6][7][8]. In those studies, the general purpose was in-situ polymerization of various polymers to fix boron compounds into the cell walls.…”
