ALKOXYSILANE-BASED FUNCTIONAL CONSOLIDANTS INCLUDING PRE-TREATMENT FOR STONE CULTURAL HERITAGE

摘要

The present invention to a functional reinforcing agent for repairing stone cultural heritage which is exfoliated due to natural weathering or an artificial reason. An alkoxysilane based functional reinforcing agent including pre-treatment for preserving stone cultural heritage has a feature of comprising: an alkoxysilane based pre-treating agent which has reactor to react with epoxy group; a functional filler which has epoxy group and is applied on the upper side of the alkoxysilane based pre-treating agent; an alkoxysilane based reinforcing agent which comprises by including alkoxysilane based resin which has epoxy group. Additionally, the present invention has an effect of increasing an interaction between the stone and the functional reinforcing agent; preventing a second damage of the stone which is caused by insufficient interaction between the functional reinforcing agent and the stone and friable property of alkoxysilane based reinforcing agent by treating with the alkoxysilane based reinforcing agent after treating with alkoxysilane based pre-treating agent which has reactive group to stone to increase reinforcing effect, after mixing the functional additive which has an epoxy group which is a reactive group in the alkoxysilane which is a main component of the alkoxysilane based reinforcing agent. The present invention has an effect to of preventing a big damage of stone heritage in which a part of weathered stone is destroyed in case the reinforcing part is destroyed by using a nano cluster filler which has a reactivity and granting a high mechanical stability of the alkoxysilane based reinforcing agent thereby having a less interaction between alkoxysilane based reinforcing agent and stone.
