AQUEOUS STRIPPING COMPOSITION HAVING IMPROVED HEAT-RESISTANCE AND MANUFACTURING METHOD THEREOF

PURPOSE: An aqueous stripping composition is provided to show an excellent heterogeneity, heat resistance and rust prevention on the surface of an inorganic material, and to show no degradation of the strippability at a high temperature of 500-600deg.C. CONSTITUTION: An aqueous stripping composition with an excellent heat resistance comprises silica powder, colloidal silica, aluminum hydroxide, magnesium hydroxide, a binder and a cross-linking agent. A manufacturing method of the aqueous stripping composition with an excellent heat resistance comprises a mixture manufacturing step (S101) by mixing silica powder, colloidal silica, aluminum hydroxide, magnesium, a binder and a cross-linking agent; a heating and stirring step (S103) of stirring and heating the mixture manufactured through the mixture manufacturing step; a polymerization step (S105) of polymerizing the mixture passed through the heating and stirring step; and a monomer removal step (S107) of removing un-reacted monomer contained in the polymerized product with a vacuum decompression after cooling the polymer passed through the polymerization step.
