摘要

The invention relates to a process of wood mineralization using carbonates and / or hydroxides to improve the essential properties of wood, i.e. fire properties, fungal resistance and mechanical properties. The wood mineralization method is a two stage process; namely in the first stage the wood is impregnated with an impregnating solution, such that it penetrates deep into the structure of the wood. The solution may contain at least one metal acetoacetate or a mixture of metal acetoacetates in any weight ratio in a solvent up to 30 wt%. Following the first stage, the impregnated wood is subject to a after-treatment phase, in which the metal acetoacetate(s) is converted into carbonate(s) and / or hydroxide(s) by regulating the temperature and humidity, and the time the impregnated wood is exposed to these conditions. The advantages of the mineralization process proposed over and above the processes used to date are that (1) carbonate(s) and / or hydroxide(s) are formed only when the impregnating solution penetrates deep into the wood's structure, (2) the process is more environmentally friendly, and (3) it is simpler.
