Abstract:
An inorganic modified phosphate adhesive for repairing fractured pottery relics was developed, and the comparison in adhesion between the modified phosphate and commonly used epoxy resin was investigated. After hygrothermal aging and dry heat aging, the adhesive strength,micro-morphology and FTIR were determined to evaluate adhesive performance, the breathability, water permeability and SEM were used to evaluate compatibility between adhesive and pottery body. The tests of breathability and water permeability and SEM are to evaluate the compatibility between adhesive and pottery body. The results revealed that inorganic modified phosphate adhesive with strong anti-aging properties and good compatibility is a novel and approving material for pottery preservation.
