Stone cultural relic reinforcement and protection method based on fluorapatite materials
A stone cultural relic reinforcement and protection method based on fluorapatite materials. The method includes the steps of firstly, mixing calcium hydroxide and anhydrous monocalcium phosphate, and dispersing the mixture in short-chain fatty alcohol to form a homogenous dispersion system, wherein the total concentration is 5.0-10.0 g/l; secondly, making the prepared dispersion system permeate a stone cultural relic to be reinforced and protected; thirdly, conducting permeation on the stone cultural relic to be reinforced and protected again through a ammonium fluoride solution with the concentration of 0.4-0.6 g/l. By means of the processing, calcium hydroxide, monocalcium phosphate and ammonium fluoride which permeate cracks and holes in the stone cultural relic can react to generate a fluorapatite reinforcement phase. Due to the extremely-low solubility, high acid resistance and firm bonding force of the fluorapatite, good overall reinforcing and surface sealing and protecting effects can be achieved for the stone cultural relic through fluorapatite.
