Problems solved by technology

However, the organic components in the weathered bone and tooth relics have been completely degraded, leaving only the inorganic component carbon hydroxyapatite, and the cracks in the residual body are developed, making it extremely decayed

Embodiment Construction

[0007] Below in conjunction with specific embodiment the present invention is described in detail:

[0008] 1. Preparation of simulated test blocks of weathered bone cultural relics

[0009] Mix the hydroxyapatite and distilled water evenly, add to the cylinder mold, and demould after compaction. The obtained test pieces were cured at room temperature and constant humidity for one week. The performance parameters of the test block are shown in Table 1.

[0010] 2. Preparation of calcium and phosphorus sources

[0011] (1) Add calcium oxide or calcium hydroxide fine powder into propanol (analytical pure), and disperse evenly by ultrasonic to obtain a stable suspension dispersion system with a mass percentage of 2.0%-15.0%, that is, the calcium source. When the mass percentage of calcium oxide or calcium hydroxide is between 2.0% and 15.0%, the amount of calcium introduced and the stability of the suspension dispersion system can be guaranteed.

[0012] (2) Add ammonium hydr...

Abstract

The invention provides a weathered bone cultural relic reinforcing protection method. The weathered bone cultural relic reinforcing protection method is characterized in that according to animal bone growth principles, a calcium resource and a phosphor source are introduced into weathered bone cultural relic and undergo a mineralization reaction at a normal temperature to produce a porous crosslinked apatite reinforcing phase in the weathered bone cultural relic. The reinforcing phase can realize re-consolidating of weathered and loose bone cultural relic and produces good protection effects.

Description

technical field [0001] The invention relates to a method for strengthening and protecting weathered bone cultural relics. Background technique [0002] The unearthed bone cultural relics can provide necessary information for paleoenvironmental, biological, geological and other research and civilization exploration projects, so its protection work also has important scientific significance and application value. However, the protection technology of such cultural relics at home and abroad is far from mature [Chadefaux C, Vignaud C, Menu M, Reiche I. Effects and efficiency of consolidation treatments on Palaeolithic reindeer antler. Multi-analytical study by means of XRD, FT-IR microspectroscopy, SEM, TEM and ??-PIXE / PIGE analyses. Applied Physics A: Materials Science & Processing, 2008, 92(1):171-177.]. At present, organic polymer materials such as acrylic resin and silicone resin are still commonly used reinforcement and protection materials for such cultural relics. Howev...
