CS245256B1 - Wood modification compound - Google Patents

Abstract

The solution concerns a mixture for obtaining wood mass modified with synthetic resin and is intended for use in the woodworking industry. The aim is to develop a mixture for modifying wood mass that allows for the preservation of the physical and mechanical properties of the modified wood mass during long-term use in an environment with fluctuating temperatures and humidity due to the reduction of the destruction of the modified polymer in the wood mass. The mixture for modifying wood mass is prepared on the basis of phenolfurfuralformaldehyde resin. The new feature of the solution is that ferrocene or monoacetylferrocene is added to the known mixture as a stabilizer for the process of destruction of the modified polymer. The starting ingredients are taken in this ratio /wt. %/: phenolfurfuralformaldehyde resin 98.5 to 99.5 and ferrocene or monoacetylferrocene 0.5 to 1.5.
