SYNTHESIS AND APPLICATION OF HYDROPHOBIC ORGANOSILICONE COMPOUNDS BASED ON TETRAETHOXYSILAN
Keywords:
hydrophobic organosilicon compound, tetraethoxysilane, urea-formaldehyde adhesive, reed-shavings boards, sol-gel process, formaldehyde emission, mechanical strength, environmental safety.Abstract
This article describes the process of synthesizing hydrophobic organosilicon compounds based on tetraethoxysilane using the sol-gel method and their addition as a modifier to urea-formaldehyde adhesive. The modified adhesive was tested in the production of reed-stem panels. As a result, the water resistance of the panels increased by 20-30%, mechanical strength by 15-25%, and formaldehyde emission decreased to a level below 0.1 ppm.
